T-Mobile Raised Prices, AT&T Lowered Them

If it seems like carrier data plans change every few months, that's because they do. As customers rely more and more on wireless data, carriers appear to be getting competitive with their data plans. Some are good deals. Others are not.

This week, T-Mobile raised the price of its unlimited plan, but offered some new benefits to others. AT&T lowered the price of its 2 GB data plan.

Here's what's changing.

T-Mobile

$50 per month gets you 1 GB of high speed data plus unlimited calls and texting. The plan used to give you 500 MB of data. So this could be a good deal for light data users. $60 now gets you 3 GB of data. It used to be 2.5 GB. That's also a better deal.

But the highest tier, the one that offers unlimited calls, texts, and high-speed data, is now more expensive. It costs $80 per month instead of $70. However, you do get 5 GB of tethering, meaning you can use your phone as a WiFi hotspot to access the Internet on your computer or other device. The top plan used to only give you 2.5 GB of tethering.

If you're already a T-Mobile customer, those new data tiers will kick in automatically. However, if you have the highest tier, you won't see a price increase. So don't worry. T-Mobile will "grandfather" you into the plan you originally signed up for.

AT&T

AT&T dropped the price of its 2 GB data plan. It now costs $65 per month, which is $15 cheaper than it was before. You get 2 GB of data per month, plus unlimited calls and texts. It costs another $25 per month if you want to share that 2 GB data bucket with another smartphone on your plan.
