Metro by T-Mobile’s $40 Period plan is the entry-level tier of Metro’s three-plan unlimited lineup ($40 / $50 with AutoPay / $60 with AutoPay), and the most common starting point for new Metro customers. Despite frequent online confusion calling it a “promo,” Metro’s own page confirms this is the carrier’s permanent base unlimited rate — and Metro’s 5-year price guarantee locks the rate for current and new customers.
After evaluating Metro $40 Period against the rest of Metro’s lineup, Metro’s competing 6-Month Unlimited bulk-pricing tier, and competing T-Mobile-network MVNOs (Mint Mobile, US Mobile), here’s what the $40 plan actually delivers — and where the alternatives win.
At a Glance
| Network | T-Mobile (5G + 4G LTE; potential slowdown after 35GB during congestion) |
| Price (1 line, all-in) | $40/mo (taxes and fees included) |
| Pricing nature | Permanent rate (not introductory) — 5-year price guarantee |
| High-speed data | Unlimited (potential slowdown after 35GB during congestion) |
| Hotspot | NOT included |
| Video | Standard definition (~480p) on cellular |
| 5G access | Yes (compatible device required) |
| AutoPay | No discount on $40 tier |
| Companion offer | 6-Month Unlimited at $20/mo ($120 upfront, BYOD, new customers) |
| Contract | None |
| Pricing model | All-in (taxes/fees included) |
Why “$40 Period” Isn’t a Promo
This is the most important detail to understand correctly: Metro’s $40 plan is NOT a promotional or introductory rate. Many reviews and aggregators describe it as a promo because Metro frequently bundles it with new-customer offers (free phones, port-in incentives) — but the underlying $40/month rate is Metro’s permanent standard pricing for this tier.
Per Metro’s own product page: “This monthly price is not an introductory rate and does not require a yearly contract. Does not include AutoPay or other discounts.”
The 5-year price guarantee: Metro guarantees that “the price of talk, text, and 5G smartphone data on our network for at least 5 years while you are on an eligible plan.” Your guarantee starts when you activate or switch to an eligible plan and doesn’t restart if you add a line or change plans after that. Per-use charges, plan add-ons, third-party services, and network management practices aren’t included.
Practical implication: Unlike Mint Mobile’s renewal pricing tiers (which step up dramatically if you don’t commit annually) or US Mobile’s first-year promo pricing (which converts to higher rates in year two), Metro’s $40 rate is locked. You won’t experience rate shock at month 12 or year 2.
Pricing: Simple All-In Structure
Metro’s $40 Period structure is straightforward — one of the simplest in prepaid:
Monthly rate: $40/month
Taxes and regulatory fees are included — the $40 you see at checkout is the $40 you pay each month. No surprise charges on your bill.
No AutoPay discount on this tier. AutoPay enrollment doesn’t change the $40 rate. (AutoPay does affect Metro’s $50 and $60 plans differently — $50 with AutoPay vs $55 first month, for example.)
Multi-line discounts: Metro’s multi-line structure on the $40 plan tier is less aggressive than the unlimited tier — verify on metrobyt-mobile.com if you’re considering 2+ lines, since Metro often runs promotional multi-line pricing that varies by month.
Companion offer — 6-Month Unlimited at $20/mo: For new customers who can prepay $120 upfront and bring their own compatible device, Metro offers a 6-Month Unlimited plan at half the $40 monthly rate. Same network access, same general feature set, but with 6-month commitment requirement and BYOD restriction. For users who can commit, this is dramatically better value.

What “Unlimited” Actually Means on $40 Period
Metro’s $40 plan is marketed as “unlimited talk, text, and data” — and the practical structure has an important threshold to understand.
The plan includes unlimited data with a 35GB monthly threshold. Per Metro’s own footnote: “If you use more than 35GB/mo. ($40 Period), you may temporarily notice slower speeds for the rest of the billing cycle when our network is busy.”
Practical implications:
- Below 35GB monthly: You experience standard T-Mobile-network performance with potential MVNO deprioritization during major congestion peaks
- Above 35GB monthly during congestion: Speeds may be reduced for the rest of the billing cycle when the network is busy
- Above 35GB monthly without congestion: Speeds remain at full T-Mobile-network levels
For users who stay reliably under 35GB monthly, the threshold rarely matters. For users who heavily depend on cellular data (rideshare drivers, mobile professionals, heavy streamers on cellular), stepping up to Metro’s $50 plan with AutoPay raises the threshold to 50GB and adds 8GB hotspot.
Video streaming on cellular is capped at standard definition (~480p) per Metro’s documentation. This affects Netflix, YouTube, and other streaming services on cellular. Wi-Fi streaming is unaffected by this cap.
Network and Coverage
Metro by T-Mobile is owned and operated by T-Mobile and runs on T-Mobile’s nationwide 5G and 4G LTE network — the same towers as direct T-Mobile postpaid customers. Coverage is strong in major metros and increasingly competitive in suburban areas, with continuing expansion of T-Mobile’s Ultra Capacity 5G in many markets.
5G access is included with all Metro plans, but requires a compatible device. T-Mobile’s network coverage has improved substantially in recent years and now ranks competitively with Verizon and AT&T for many markets.
Network priority is the standard MVNO trade-off. For routine daily use in non-congested areas, performance is essentially identical to T-Mobile postpaid. During major congestion peaks (stadium events, airport peak hours, downtown cores at busy times), Metro customers may see reduced speeds.
For users in T-Mobile’s stronger markets, this rarely matters in practice. For users in T-Mobile-weak markets or rural areas where coverage is marginal, no Metro plan can fix that.

What You Get
Every Metro by T-Mobile $40 Period plan includes:
- Unlimited talk and text on T-Mobile’s network
- Unlimited data (potential slowdown after 35GB during congestion)
- 5G access where available (compatible device required)
- All-in pricing (taxes and regulatory fees included)
- 5-year price guarantee for talk, text, and 5G data
- Metro retail support at thousands of locations nationwide
- Phone support and online chat
- Metro app for self-service account management
- T-Mobile-owned customer support infrastructure
- Bring-Your-Own-Device flexibility
- No contract or early termination fees
- Eligibility for current promotional offers (free phones, port-in incentives)
What You Don’t Get
The $40 Period plan has substantial gaps versus higher Metro tiers and competing plans:
- No mobile hotspot — must step up to $50 plan with AutoPay (8GB) or $60 plan (25GB)
- Standard-definition video on cellular — no HD or 4K cellular streaming
- No bundled streaming services — no Amazon Prime, Disney+, Netflix, etc.
- 35GB threshold — heavy users may experience slowdowns during congestion
- No AutoPay discount — flat $40 regardless of payment method
- No multi-line aggressive scaling on $40 tier — verify current multi-line structure
- No watch lines bundled — separate add-on required
- Metro retail variability — quality of in-store experience varies by location
- No premium customer service tier — standard MVNO-level support
Real-World Performance
In daily use within typical conditions, Metro $40 Period delivers solid T-Mobile-network performance for users who don’t push the plan’s limitations.
Calling and texting. Identical to direct T-Mobile service — voice quality and text reliability unchanged.
Web browsing and social media. Smooth on standard 5G during off-peak hours. May feel slightly slower during peak congestion in dense areas as Metro is deprioritized below T-Mobile postpaid.
Navigation and rideshare. Maps load instantly. Real-time traffic and ETA calculations stay current. Location services aren’t bandwidth-dependent, so deprioritization rarely matters here.
Streaming. Music streams at full quality. Video on cellular is capped at standard definition (~480p). On Wi-Fi, streaming quality is unaffected.
Video calls. Zoom, FaceTime, and Google Meet maintain stable quality during off-peak hours. Quality may dip during congestion peaks.
Heavy data usage. Users approaching or exceeding 35GB monthly may notice slowdowns during congestion. For users consistently using 35GB+ monthly, Metro’s $50 plan with AutoPay raises the threshold to 50GB and adds 8GB hotspot — the natural upgrade path.
Hotspot tethering. Not included on $40 plan. Users who tether at all need to step up to $50 with AutoPay (8GB) or $60 (25GB).
Customer Experience
Metro by T-Mobile is owned and operated by T-Mobile and benefits from T-Mobile’s customer infrastructure:
- In-store retail support at thousands of Metro retail locations nationwide (more than most MVNOs)
- Phone support with traditional 1-800 customer service
- Metro app for self-service account management
- Online chat through metrobyt-mobile.com
- T-Mobile ownership benefit — Metro has the financial backing of T-Mobile’s parent company
What works well:
- Walk-in support at Metro retail stores nationwide
- Metro app well-designed for self-service
- All-in pricing with no surprise taxes/fees
- Strong promotional structure (free phones, port-in deals)
- 5-year price guarantee for predictable long-term costs
- T-Mobile-equivalent network access without postpaid pricing
Where it falls short:
- Metro retail experience varies by location quality
- Phone support hours and quality vary by region
- T-Mobile network outages affect Metro service identically (no separate guarantee credits)
- Some advanced features (eSIM transfers, complex porting issues) may have more friction than direct postpaid
- No direct line to T-Mobile premium customer service
How Metro $40 Period Compares
Metro $40 Period has natural alternatives within Metro’s lineup, in Metro’s own bulk-pricing tier, and across competing T-Mobile-network plans. Here’s how the comparison shakes out.
Metro $40 Period vs. Metro 6-Month Unlimited
| Feature | $40 Period | 6-Month Unlimited |
|---|---|---|
| Effective rate | $40/mo monthly | $20/mo ($120 upfront) |
| Annual cost (12 months) | $480 | $240 (if renewable; verify) |
| Eligibility | All customers | New customers only |
| Device | BYOD or purchase | BYOD required |
| Billing | Monthly | Single 6-month prepayment |
| Threshold | 35GB | Verify (likely same) |
| Hotspot | None | None |
The 6-Month Unlimited at $20/mo is dramatically better value — half the cost with comparable features — but requires $120 upfront commitment, BYOD, and is restricted to new customers. For users who fit the profile, the bulk pricing wins comprehensively. For monthly billing users or those without compatible BYOD devices, $40 Period is the right pick.
Metro $40 Period vs. Metro $50 Plan with AutoPay
| Feature | $40 Period | $50 Plan with AutoPay |
|---|---|---|
| Effective rate | $40/mo all-in | $50/mo all-in (AutoPay required) |
| Threshold | 35GB | 50GB |
| Hotspot | None | 8GB included |
| Video | SD only | SD only |
| Network | T-Mobile (deprioritized) | T-Mobile (deprioritized) |
For $10/month more, the $50 plan with AutoPay adds 8GB hotspot AND raises the data threshold from 35GB to 50GB. For users who tether at all OR consistently approach 35GB monthly, the $10 upgrade is genuinely worth it. For users who stay reliably under 35GB and never tether, the $40 plan saves money.

Metro $40 Period vs. Mint Mobile Unlimited
| Feature | Metro $40 Period | Mint Mobile Unlimited |
|---|---|---|
| Effective rate | $40/mo monthly all-in | $30/mo (12-month bulk; $360 upfront) |
| Renewal rate | Same $40 (5-yr guarantee) | $35-45 at 3-mo renewal |
| Network | T-Mobile (deprioritized) | T-Mobile (deprioritized) |
| Threshold | 35GB | 50GB before potential deprioritization |
| Hotspot | None | Up to 20GB |
| Mexico/Canada | Verify (limited) | Free MX/Canada talk/text + 3GB Canada data |
| In-store support | Yes (Metro retail) | No (digital-only) |
Mint Mobile Unlimited at $30/mo (12-month bulk) on the same T-Mobile network delivers more high-speed threshold (50GB vs 35GB), 20GB hotspot, and Mexico/Canada features at $10/month less than Metro $40 Period — at the cost of $360 upfront commitment versus monthly billing. For users committed to T-Mobile’s network who can commit annually with BYOD, Mint is dramatically better value. Metro $40 Period wins for users wanting monthly billing flexibility, retail support, or the 5-year price guarantee.

Metro $40 Period vs. Cricket Smart Unlimited
| Feature | Metro $40 Period | Cricket Smart Unlimited |
|---|---|---|
| Price | $40/mo all-in | $50/mo standard / $45/mo AutoPay all-in |
| Network | T-Mobile (deprioritized) | AT&T (deprioritized) |
| Threshold | 35GB | None (unlimited high-speed) |
| Hotspot | None | 15GB included |
| Mexico/Canada | Verify (limited) | Full data roaming included |
| Cloud storage | None | 100GB |
| In-store support | Yes (Metro retail) | Yes (Cricket retail) |
For $5/month more (with AutoPay), Cricket Smart Unlimited on AT&T’s network delivers 15GB hotspot, full Mexico/Canada data roaming, 100GB cloud storage, and no 35GB threshold — meaningful upgrades for users on AT&T coverage. Metro $40 Period wins specifically for users who need T-Mobile’s network or want the 5-year price guarantee. For users without specific T-Mobile preference, Cricket Smart’s $5/month premium is worth it.

Metro $40 Period vs. US Mobile Unlimited Starter
| Feature | Metro $40 Period | US Mobile Starter |
|---|---|---|
| Effective rate | $40/mo monthly all-in | $22.50/mo standard / $16.60 first-year promo / $199 annual |
| Network | T-Mobile (deprioritized) | Pick one of 3 (VZ/T-Mo/AT&T) |
| Threshold | 35GB | Unlimited |
| Hotspot | None | 20GB separate bucket |
| In-store support | Yes (Metro retail) | No (digital-only) |
| Pricing transparency | All-in | All-in |
| Promo nature | Permanent rate | First-year promo only |
US Mobile Unlimited Starter at first-year promo pricing ($16.60/mo) dramatically beats Metro $40 Period — multi-network choice including T-Mobile’s Light Speed network, 20GB separate hotspot, no 35GB threshold, all at less than half the monthly cost. For first-year users prioritizing maximum value, US Mobile Starter is meaningfully better. Metro $40 Period wins for users who prefer the 5-year price guarantee predictability or want walk-in retail support.

Who Should Choose Metro $40 Period
Wi-Fi-first households on T-Mobile’s network. If you spend most of your day on home or office Wi-Fi and need T-Mobile-network coverage with monthly billing flexibility, Metro $40 Period delivers solid value.
Users wanting monthly billing without bulk commitment. Unlike Mint Mobile (which rewards annual commitment with lowest pricing) or Cricket Multi-Month (which requires 12-month BYOD commitment), Metro $40 Period delivers competitive pricing with monthly billing.
T-Mobile prepaid first-timers. Metro is T-Mobile’s official prepaid brand. The $40 Period plan is a natural starting point with retail support, app management, and the 5-year price guarantee for predictability.
Users who don’t qualify for the 6-Month Unlimited promo. If you’re not eligible for new-customer pricing (you’ve been a Metro or T-Mobile customer in the past 180 days, or you don’t have a compatible BYOD device), $40 Period is your default option.
Users wanting all-in pricing transparency on T-Mobile’s network. $40 is genuinely $40 — no surprise taxes or fees. Cleaner than Verizon Welcome ($65 + taxes ≈ $71 effective).
Light data users in non-congested markets. Users who stay reliably under 35GB monthly get full T-Mobile-network performance at the lowest postpaid-style price.
Users wanting 5-year price guarantee predictability. Unlike Mint’s renewal pricing tiers or US Mobile’s first-year promo conversions, Metro guarantees the rate won’t change for 5 years.
Users wanting Metro retail support. Walk-in support at thousands of Metro retail locations is a meaningful benefit versus pure-digital MVNOs.

Who Should Skip Metro $40 Period
New customers who can prepay 6 months upfront with BYOD. Metro 6-Month Unlimited at $20/mo ($120 upfront) is half the price for the same essential features. Don’t choose $40 Period if you qualify for the 6-Month promo.
Anyone who tethers at all. Metro’s $50 plan with AutoPay at $10/month more includes 8GB hotspot and raises the data threshold to 50GB. The $10/month upgrade is meaningful for users who tether at all.
Users committed to bulk pricing on T-Mobile. Mint Mobile Unlimited at $30/mo (12-month bulk) saves $10/month versus Metro $40 Period AND adds 20GB hotspot AND raises the threshold to 50GB. For users committed to T-Mobile’s network who can prepay $360, Mint is dramatically better value.
Users on AT&T or Verizon coverage. No Metro plan can fix poor T-Mobile coverage. Cricket Smart Unlimited on AT&T or Visible+ Plan on Verizon are alternative networks at competitive pricing.
Users who want HD or 4K cellular streaming. Metro $40 caps cellular video at SD. For HD on cellular, Metro’s $60 plan or T-Mobile postpaid plans are required.
Users who need international features. Metro $40 Period has limited international structure. For Mexico/Canada inclusion, Cricket Smart Unlimited (full MX/Canada data) or T-Mobile postpaid plans (215+ countries) deliver more.
Heavy data users (35GB+ monthly). Users approaching or exceeding 35GB regularly may notice slowdowns during congestion. Metro’s $50 plan with AutoPay raises the threshold to 50GB; Mint Mobile Unlimited offers similar relief.
Users wanting promotional first-year pricing. US Mobile Unlimited Starter at $16.60/mo first-year promo is dramatically cheaper for first-year users — but converts to higher renewal rates. Metro’s pricing is more predictable; US Mobile’s is cheaper short-term.
Users wanting bundled streaming or cloud storage. Metro $40 has neither. Cricket Supreme Unlimited bundles HBO Max with Ads + 150GB cloud at $55 AutoPay; Cricket Smart Unlimited adds 100GB cloud at $45 AutoPay.
How to Switch to Metro $40 Period
The switching process is fast and can happen online or in-store:
- Check eligibility for the 6-Month Unlimited promo first. If you’re a new customer (haven’t been with Metro or T-Mobile in the past 180 days) AND have a compatible BYOD device, Metro 6-Month Unlimited at $20/mo ($120 upfront) is half the price for similar features. Don’t default to $40 Period without checking this first.
- Verify T-Mobile coverage at your home, work, and frequent travel destinations using T-Mobile’s coverage map. Metro coverage mirrors T-Mobile directly.
- Check phone compatibility. Most modern unlocked phones work; Metro’s website includes a compatibility checker. Use eSIM for fastest activation.
- Confirm you genuinely don’t need hotspot. If you tether at all, step up to Metro’s $50 plan with AutoPay or choose a different carrier with hotspot included.
- Consider current promotions. Metro frequently runs port-in promotions (free phones, virtual Mastercard rewards). Verify what’s available at signup.
- Get your account info from your current carrier — account number and Number Transfer PIN.
- Sign up via metrobyt-mobile.com or in-store. In-store activation may include device promotions and immediate eSIM activation.
- Activate your service. eSIM activation is instant on supported phones; physical SIM ships in 1-3 business days.
- Take advantage of the 5-year price guarantee — your rate is locked starting at activation.
Don’t cancel your old service before the port completes — Metro handles cancellation automatically once your number transfers.
Final Verdict
Metro by T-Mobile $40 Period earns 6.6/10 in our cross-carrier rankings — a solid entry-tier prepaid plan that fits a specific buyer profile but doesn’t suit users who can step up or commit annually.
The combination of $40/month all-in pricing, full T-Mobile-network access, 5-year price guarantee, and Metro retail support delivers genuine value for users who want predictable monthly costs on T-Mobile’s network. For users who don’t qualify for the 6-Month Unlimited promo (existing Metro/T-Mobile customers, or those without compatible BYOD devices), $40 Period is the right Metro entry point.
For nearly everyone else, alternatives exist:
For new BYOD customers who can prepay, Metro 6-Month Unlimited at $20/mo delivers half the cost for similar features — the best value path within Metro.
For users who tether even occasionally, Metro’s $50 plan with AutoPay at $10/month more includes 8GB hotspot and raises the data threshold to 50GB — meaningful upgrade.
For users committed to T-Mobile bulk pricing, Mint Mobile Unlimited at $30/mo (12-month bulk) is $10/month cheaper than Metro $40 Period AND includes 20GB hotspot AND raises the threshold to 50GB.
For users wanting maximum value with multi-network choice, US Mobile Unlimited Starter at $16.60/mo first-year promo delivers the strongest economics, with the trade-off of digital-only support and promo conversion in year two.
For AT&T-network preference, Cricket Smart Unlimited at $45 AutoPay is just $5/month more with 15GB hotspot, full Mexico/Canada data, and 100GB cloud storage included.
The honest takeaway: Metro $40 Period is a fair-value default for T-Mobile-network users who want monthly billing simplicity. It’s rarely the best Metro option, since the 6-Month Unlimited promo at $20/mo dominates on price for eligible users. It’s also rarely the best T-Mobile-network MVNO option, since Mint Mobile delivers more for less with annual commitment. It’s the right pick specifically for users who fit the narrow profile: monthly billing, no bulk commitment, T-Mobile network preference, no hotspot need.

Frequently Asked Questions
Is Metro by T-Mobile $40 Period worth it? For users wanting T-Mobile-network unlimited service with monthly billing flexibility and the 5-year price guarantee, yes. It earns 6.6/10 in our rankings as a solid entry-tier prepaid plan. For new customers eligible for Metro 6-Month Unlimited at $20/mo, the bulk-pricing tier is dramatically better value — verify eligibility before defaulting to $40 Period.
Is Metro $40 Period a promo? No. Despite frequent confusion, Metro’s own page explicitly states the rate is not introductory: “This monthly price is not an introductory rate and does not require a yearly contract.” Metro also offers a 5-year price guarantee on talk, text, and 5G data. The $40 rate is Metro’s permanent base unlimited pricing — not a promotional offer that converts to higher rates.
Does Metro $40 Period include hotspot? No. Hotspot is NOT included on the $40 plan and cannot be added as an add-on. For mobile hotspot capability, step up to Metro’s $50 plan with AutoPay (8GB hotspot included) or $60 plan (25GB hotspot). For users who need any tethering at all, the $10/month upgrade to $50 with AutoPay is genuinely worth it.
What happens after I use 35GB on Metro $40? Per Metro’s documentation: “If you use more than 35GB/mo., you may temporarily notice slower speeds for the rest of the billing cycle when our network is busy.” Speeds aren’t reduced unconditionally — only during network congestion. In non-congested periods, speeds remain at full T-Mobile-network levels. Heavy users in dense urban areas may notice the impact more than users in rural or suburban areas.
Are taxes and fees included in the $40 price? Yes. Metro uses all-in pricing — the $40/month rate includes taxes and regulatory fees. This contrasts with major postpaid plans (Verizon, AT&T) which typically charge 8-15% additional taxes on top of advertised rates. The $40 you see at signup is the $40 you pay each month, with no surprise charges.
What’s the 5-year price guarantee? Metro guarantees that the price of talk, text, and 5G smartphone data won’t change for at least 5 years on eligible plans. The guarantee starts when you activate and doesn’t restart if you change plans or add lines. Per-use charges, plan add-ons, and third-party services aren’t covered. This is a meaningful predictability advantage over Mint Mobile’s renewal tiers.
What’s the difference between Metro $40 and Metro $50 plans? Metro $40 Period ($40/mo all-in) provides unlimited data with 35GB threshold and no hotspot. Metro $50 plan with AutoPay ($50/mo all-in) raises the data threshold to 50GB AND includes 8GB high-speed hotspot. The $10/month upgrade is genuinely worth it for users who tether at all OR consistently approach 35GB monthly. For Wi-Fi-first users who never tether, $40 Period saves money.
Can I bring my own phone to Metro $40 Period? Yes. Metro is a Bring-Your-Own-Device carrier on T-Mobile’s network. Most modern unlocked phones (iPhones XS and newer, recent Samsung Galaxy and Google Pixel devices) work without issue. Use Metro’s free compatibility checker on metrobyt-mobile.com to confirm your specific device. eSIM-capable phones activate fastest. If your phone is locked to a previous carrier, request an unlock first.
Carrier offerings change frequently. Pricing, plan terms, network performance, and promotional offers verified at publication but may differ at time of reading. Always confirm on the carrier’s official website before signing up.
