T-Mobile is back with some very aggressively priced packages on data plans, including one offering almost a year of free data. But more impressively, customers also have a chance to buy a 4G LTE-equipped tablet for the same price as a Wi-Fi only version.

T-Mobile’s Simple Starter Plan – $40/mo Unlimited Talk, Text + 500MB 4G LTE data

Simple Starter provides an affordable $40 unlimited talk and text offer with a 500MB entry-level data allowance with no overlimit fees. T-Mobile is intending to shame AT&T and Verizon to ditch overlimit fees on their data plans by demonstrating that a mobile carrier can automatically shut off data when a customer reaches their allowance, inviting them to voluntarily pay extra for continued service instead of slapping overlimit fees on the bill automatically. T-Mobile’s “data pass” resets the allowance, but often for only a limited time, such as $10 for one extra gigabyte, expiring after one week.

Still, the plan may be a comfortable fit for anyone unlikely to run a lot of data applications on their phone and prefer the convenience of having access to 4G speed when they need it. Some other carriers force value-priced plan customers to use 3G-only service, especially in the prepaid market.

The biggest problem wireless carriers have selling tablets is justifying the cost of 4G-equipped models that typically run at least $100 more than a Wi-Fi only version. As a result, 4G-equipped portable devices like these just don’t sell well. T-Mobile is tackling that problem by discounting the MSRP of their 4G tablets to the same price one would pay for a Wi-Fi only equipped device.

T-Mobile is also offering trade-in deals for tablet customers who want something new.

“Now you can come to T-Mobile, trade it in and upgrade to a 4G LTE-enabled model and pay no more than you’d pay for the cheaper Wi-Fi-only model,” said T-Mobile’s Mike Sievert. “For example, you might choose to pay the Wi-Fi price of $499 instead of $630 for the 4G LTE-enabled iPad Air (16GB). Or pay the Wi-Fi price of $200 instead of $312 for the 4G LTE Samsung Tab 3. And remember, on all of these tablets you might qualify for no interest financing with nothing down.”

T-Mobile will also cover any early termination fees charged by your current carrier if you purchased one on contract.

Customers will also find good deals on tablet data plans. Beginning April 12, new and existing postpaid voice customers can add tablets to their plans and get nearly 1.2GB of data per month free for the rest of this year. In 2015, customers can keep that data plan for $10 a month or revert to T-Mobile’s 200MB for life data plan, free of charge. Customers who want a 3 or 5GB data plan will find them priced $10 off for the rest of 2014. Be aware that the free 1GB data offer does seem to require at least one voice plan, whether that’s an existing one or one you sign up for in store when you get your tablet.
