One of the things that makes Mint Mobile stand out against the competition is its unique pricing structure; instead of paying for one month of service at a time, you buy months in bulk. Each plan comes with unlimited talk, text, and 2G data, and you simply select your 4G data allotment and bulk amount — three, six, or twelve months at once — and pay a lump sum that's sometimes even cheaper than a single month with a major carrier.

Starting January 29th, Mint will be refreshing its plans with higher data allotments and slightly higher pricing. Mint's baseline three-month plan, which previously netted you 2GB of LTE each month for $23/mo, is being bumped up to $25/mo with 3GB, while the 5GB plan is going from $30/mo to $35/mo with 8GB. The top-end 10GB plan is moving from $38/mo to $45/mo with a whopping 12GB of LTE data. Presumably, Mint's lower introductory rates for first-time customers will stay the same.

The six-month plans are also increasing a bit in both price and data provisions. The previous $18/mo 2GB plan is now $20/mo for 3GB. $24/mo for 5GB becomes $25/mo for 8GB, and $30/mo for 10GB becomes $35/mo for 12GB. If you're buying your service a year at a time, the prices actually aren't changing at all — you'll get the higher data allotments for the same $15/mo, $20/mo, and $25/mo bundles.

The good news is that if you already have Mint service, you'll be grandfathered into the current pricing and still get the new, higher data allowances. That also applies to new customers that sign up before the changeover on the 29th — meaning this is a great time to sign up for Mint if you've been considering it. So long as there's solid T-Mobile coverage in your area, it's a great option to save you a ton on phone service.
