Metro by T-Mobile is running a web-exclusive offer: one line of unlimited talk, text and 5G data for $15 a month for the first three months, then $25 a month with AutoPay. Taxes and fees are included at both prices, there is no activation fee when you order online, and you can bring a number or take a new one. The offer is real and the arithmetic is simple, but two things about it are worth knowing before you sign up — what the $25 renewal does not include, and the fact that Metro sells a different plan that costs exactly the same over six months.
What the $15 actually buys
| First 3 months | Month 4 onward | |
|---|---|---|
| Price | $15/mo | $25/mo with AutoPay |
| Data | Unlimited 5G | Unlimited 5G |
| Talk & text | Unlimited | Unlimited |
| Taxes and fees | Included | Included |
| Hotspot | None | None |
| Included extras | T-Mobile Tuesdays, Scam Shield | T-Mobile Tuesdays, Scam Shield |
| Activation fee | None when ordered online | — |
Metro's own plan grid labels this record “Metro by T-Mobile BYOD $25 UNL.” That is the plan you are buying; the $15 is a limited-time discount applied to the first three billing cycles. Judge it on $25, which is what you pay from month four for as long as you keep the line.
The six-month total is identical to Metro's prepaid plan
Three months at $15 is $45. Three months at $25 is $75. Six months costs $120. Metro also sells a six-month unlimited plan for $120 due today, which it advertises as $20 a month against a $40 list price. The two offers reach the same number by different routes.
| $15 intro offer | 6-month prepaid plan | |
|---|---|---|
| Cost of first 6 months | $120 | $120 |
| Paid | Monthly | $120 upfront |
| Price after 6 months | $25/mo | Renews at Metro's then-current rate |
| Eligibility | New number or bring yours | New customers who bring a phone |
| Taxes and fees | Included | Included |
| 5-year price guarantee | Yes | Yes |
The $25 tier includes no hotspot
This is the detail most likely to matter. Metro's $25 BYOD plan lists unlimited 5G data, unlimited talk and text, T-Mobile Tuesdays and Scam Shield. Hotspot data is not among them. The next rung up carries it.
| Plan | Price | Hotspot | Notable |
|---|---|---|---|
| $25 BYOD unlimited | $25/mo AutoPay ($15 first 3 months) | None | Web exclusive |
| $30 unlimited | $30/mo AutoPay, $35 first month | 10GB | Web exclusive |
| $35 unlimited | $35/mo AutoPay, $40 first month | 10GB | Unlimited Mexico & Canada calls and texts, up to 5GB roaming data |
| $40 Period | $40/mo, no AutoPay requirement | None | Web exclusive |
| $50 unlimited | $50/mo AutoPay, $55 first month | 8GB | Phone upgrades included, 100GB Google One |
| $60 unlimited premium | $60/mo AutoPay, $65 first month | 25GB | Amazon Prime, HD video, unlimited texting to 210+ countries, $5 watch and tablet lines |
Two things stand out reading down that ladder. Five dollars above the $25 plan buys 10GB of hotspot, and the $35 tier is the only one that includes Mexico and Canada calling in the price rather than as a $5 monthly add-on. The $35 tier is also the one plan in the grid whose benefit list does not mention the 5-year price guarantee.
Where the unlimited data stops behaving like unlimited
Metro's footnote is specific: if you use more than 35GB in a month, you may temporarily notice slower speeds for the rest of the billing cycle when the network is busy. Video streams in SD on this tier. Metro runs on T-Mobile's network and may be slower than T-Mobile itself during congestion, which Metro states directly.
One line of unlimited 5G with taxes and fees included, then $25/mo with AutoPay. Web exclusive, no activation fee online.
See the offer at Metro →Who should take it
The $15 offer is a good deal for someone bringing a phone who wants unlimited data with taxes already in the price and no commitment. At $25 standing it stays competitive, and the 5-year price guarantee on talk, text and 5G data is unusual at this end of the market. Skip it if you tether — the plan has no hotspot allowance, and $30 fixes that. And if you already know you are staying six months, compare it against the $120 prepaid plan rather than against other carriers, because Metro's better offer here is its own.
