T-Mobile announced today that beginning Nov 1, it's giving anyone with a tablet that can connect to the T-Mobile network 200 MBs per month of free data for the life of the tablet.
There are still some details that aren't clear yet but according to T-Mobile this is a no-commitment offer that's open to everyone regardless whether or not they are a paying T-Mobile customer.
It sounds like anyone with a compatible tablet can pop in a T-Mobile SIM, sign up as a free data user and immediately start getting 200 MB of data, including 2G, 3G, 4G HSPA+ and LTE, for the life of that tablet.
If use up your 200 MB and need more data, T-Mobile will offer daily, weekly and monthly passes. The following prepaid passes will be available:
$10 500 MB Day Pass
$15 1 GB Week Pass
$20 500 MB Month Pass
$20 Monthly Pass users can add an additional 2 GB of high speed data for $10 if needed.
Also beginning Nov 1, T-Mobile will begin selling the Wi-Fi + Cellular versions of the Pad Air and iPad Mini. The Wi-Fi + Cellular iPad Mini with Retina display will be available from T-Mobile later in November. T-Mobile is already selling the 2013 Nexus 7 and Samsung Galaxy Tab 2 10.1 and will be adding more tablets to its lineup soon.
T-Mobile is calling the free data program Tablets Un-Leashed. Many details of the program are still unclear including pricing and availability of SIMs and what devices T-Mobile recognizes as eligible tablets. This article will be updated as new details emerge.
Updated 10/23: clarified that the 200 MB of free data is available to all tablet users and that it includes all types of data, not just LTE.
