Mint Mobile has quietly increased the data allowance on three of its four prepaid plans without raising prices, the low-cost carrier confirmed this month — and the extra data applies to both new sign-ups and existing subscribers. The move lands in the middle of a prepaid price war in which nearly every major budget carrier now sells “unlimited” service for about $25 a month.
Mint, which runs on T-Mobile’s network, bumped its entry plan from 5GB to 6GB, its mid-tier plan from 15GB to 17GB, and its higher-data plan from 20GB to 23GB. The Unlimited plan is unchanged. Prices stayed flat, so the change is effectively a free upgrade for current customers.
What the new Mint Mobile plans cost
Mint sells service in prepaid blocks, and its headline rates require paying 12 months up front. Here is the updated lineup:
| Plan | Old data | New data | Price (12-month) | Effective monthly |
|---|---|---|---|---|
| Entry | 5GB | 6GB | $180 / year | $15 |
| Mid | 15GB | 17GB | $240 / year | $20 |
| High | 20GB | 23GB | $300 / year | $25 |
| Unlimited | Unlimited | Unlimited | $360 / year | $30 |
New customers can also start on a lower introductory rate for the first three months before the plan renews at the standard price, a promotion Mint runs to pull switchers away from the big three carriers.
How Mint’s new plans compare to the $25 field
The upgrade matters because Mint’s rivals have converged on the same price. At roughly $25 a month, a budget shopper can now choose between very different data structures:
| Carrier | ~$25 plan | Network |
|---|---|---|
| Mint Mobile | 23GB (annual prepay) | T-Mobile |
| Visible | Unlimited, taxes & fees included | Verizon |
| Boost Mobile | 30GB “Forever” (AutoPay) | Own network + partners |
| Metro by T-Mobile | Unlimited high-speed | T-Mobile |
The takeaway for prepaid users: if you consistently use less than ~23GB and don’t mind paying a year in advance, Mint’s upgrade makes it one of the cheapest ways to stay on T-Mobile’s network. Heavy users who want a true unlimited bucket without an annual commitment still get more from Visible or Metro at the same monthly price.
Who should switch — and who shouldn’t
Existing Mint customers don’t need to do anything; the extra data is applied to the matching plans. For anyone shopping around, the decision now comes down to whether you value Mint’s low annual cost or a rival’s no-commitment unlimited data. Either way, the days of paying $40 or more for a basic prepaid plan are effectively over.
