Ultra Mobile and Mint Mobile are two of the most talked-about budget prepaid carriers, and both run on T-Mobile's network with nationwide 5G. Coverage and speeds are effectively identical, so the choice comes down to pricing structure, international perks, and how you want to pay. Here's the category-by-category breakdown.
TL;DR: quick picks
- Minimal data: Ultra Mobile 250MB: $15/mo, month-to-month.
- Light data: Mint 5GB: $15/mo with multi-month commitment.
- Moderate: Mint 15GB: $20/mo (12-month rate).
- Higher needs, no prepay: Ultra 25GB.
- Heavy data on a budget: Mint Unlimited: ~$20–30/mo depending on term.
| Need | Mint Mobile | Ultra Mobile |
|---|---|---|
| Light data | 5GB: $15/mo with a multi-month commitment | Tiered plans, no prepay required |
| Moderate data | 15GB: $20/mo on the 12-month rate | 25GB, month to month |
| Unlimited | About $20–$30/mo depending on term | Not the strength here |
| Billing | Headline prices need multi-month prepay | No prepay commitment |
| Congestion | Slows heavy users around 35GB | Slows heavy users around 35GB |
| Support | Online only | Online only |
| Network | T-Mobile | T-Mobile |
Pricing: winner: Mint
Mint's bulk model (pay 3, 6, or 12 months upfront) buys the lowest effective rates: 6GB at $15, 17GB at $20, Unlimited at $30/mo on annual terms. Ultra runs month-to-month from $15 (250MB) through $49–59 for its unlimited tiers. Ultra wins for casual or short-term use; for anyone on a multi-month plan, Mint delivers more savings.
Coverage and speed: tie
Both ride T-Mobile's towers, the country's largest 5G footprint. Real-world 5G runs roughly 150–230 Mbps on either, dropping to ~50 Mbps when deprioritized. Mint states reduced speeds past 35GB/month; Ultra doesn't publish a cutoff but behaves similarly under congestion. Your experience depends on T-Mobile in your area, not the MVNO.
Features and perks: winner: Ultra
Ultra's signature perk is free international reach: every plan includes unlimited calling and texting to 90+ countries, with calling credits for high-traffic destinations like India and China. Mint includes free calls only to Mexico, Canada, and the UK (plus free texting to 190+ countries and paid rates to 160+). Ultra also runs a family deal, 3 unlimited lines for $85, and its Unlimited+ tier carries a 40GB hotspot vs Mint's 10GB cap. Both support BYOD, eSIM, Wi-Fi Calling, and phone financing.
Customer support: draw
Neither has stores, and both have rough support reputations — hard-to-reach live help, billing complaints on Trustpilot and BBB for both brands. Mint's 7-day money-back guarantee and solid online help center are modest advantages. Either way, expect to self-serve.
If you value international perks and pay-as-you-go flexibility, go with Ultra. If you want to maximize data for the lowest monthly spend, go with Mint.
— ShopCellPlans verdict
Final verdict
Ultra Mobile for short-term service, ultra-low-data plans, month-to-month billing, or unlimited global calling. Mint Mobile for the cheapest high-data service and flashier phone deals. If you can stomach paying a year upfront. Coverage is a wash either way.
Mint's 7-day trial kit, or T-Mobile's own 30-day trial, lets you verify coverage at your address before prepaying anything.
