T-Mobile started selling cellular iPads in 2013. When it launched the cellular model, it also launched a new plan which promised iPad customers 200MB of free LTE data per month, for the life of the tablet. It has been running this promotion for more than three years but it appears that T-Mobile is doing away with it. T-Mobile is going to stop offering 200MB of free LTE data to new iPad customers.
T-Mobile has updated its Free Data for Life support page to reflect that it will no longer offer this program for new activations starting May 7th, 2017. This means that customers who signed up for Free Data for Life on or before May 6th will receive 200MB of free data with their iPads as long as they continue on T-Mobile.
Since this free data plan is not tied to the account but to a specific device, customers who have this plan will lose it if they switch from their existing tablet to a new iPad.
The carrier has also pointed out on the support page that from now on, no new tablets that T-Mobile sells will be eligible for the Free Data for Life plan. It has decided to end it for good, even though it was one of its much-touted uncarrier initiatives back in 2013.
T-Mobile customers who want unlimited data can now subscribe to T-Mobile One and add their tablet to the plan for $20 per month.
