As of Feb. 12, 2020, AT&T pulled this plan from its website and it is no longer offered or available. This plan is officially retired, but the plan has been grandfathered for existing customers who adhere to the plan terms of service for use in tablets, which prohibit use in unauthorized devices like hotspots and routers.

This plan has been replaced by AT&T with a 25GB plan for $34.99/mo. More info on this plan is available here.

AT&T Prepaid is AT&T's own prepaid brand. For several years, they offered an unlimited tablet based plan that was of interest to nomads seeking unlimited data on a tablet device.

We have an in depth guide to all of AT&T Prepaid's many offerings, here. This guide focuses solely on the AT&T Prepaid Unlimited Tablet Plan, a popular option for AT&T coverage.

Tablet DataConnect Prepaid Unlimited Plan

The plan was a session-based prepaid plan designed for tablets, cellular-enabled cameras, and gaming devices. It was first released in 2010 with the launch of the cellular iPad, and quickly retired (but customers were grandfathered in as long as they continued to renew).

AT&T brought the plan back in June 2017 and made it available to all tablet devices. Later, cellular-enabled cameras and gaming devices were added as options, but tablets remain the most useful device for this plan.

The plan includes truly on device unlimited data, subject to network management after 22GB of usage, but does not include any mobile hotspot use.

The plan price was increased by $5/month in May 2019 and currently costs $40/month ($34.99 with auto-renew).

Many were using this plan on routers and hotspot devices, and since the retirement of the plan AT&T has continued to terminate accounts doing so.

In February 2020, AT&T officially retired the plan - grandfathering in those who utilize the plan as intended:
