According to internal T-Mobile documents obtained and verified by Android Police, the company plans to drop mobile network support for 19 devices on January 29, 2021. Impacted devices include smartphones from Google, Samsung, Sony, and more, as well as older home security cameras and wireless routers.

Here is the full rundown, as per T-Mobile’s internal list:


Google Nexus 9
Huawei Mate 8
Huawei P9
HTC Desire 10 Lifestyle
HTC Desire 650
OnePlus 1
Quanta Dragon IR7
Samsung Galaxy Note 4 (both AT&T and Verizon models; The T-Mobile version of the Note 4 is not affected)
Samsung Galaxy Note Edge
Samsung Galaxy S5 Duos
Sony Xperia Z3
Sony Xperia Z3 Compact
Sony Xperia Z3 Orion
Sony D6616 Xperia Z3 Orion
Soyea M02

Other devices:

Mikrotikls SIA_R11e-LTE6 miniPCIe modem
Netgear Arlo Security Camera System

The change affects T-Mobile, MetroPCS, and Sprint customers, but the impact will depend on which carrier’s network your device originally uses. T-Mobile and MetroPCS devices will lose all network support starting January 29, while Sprint devices will lose T-Mobile roaming connectivity but can still use Sprint’s legacy 3G network until it’s shuttered in 2023.

It’s possible there are more unsupported devices, but T-Mobile has yet to make a public announcement as of writing so we can only go off Android Police’s information. That said, T-Mobile will reportedly alert customers via SMS text starting December 28, which gives those still using these older products just a few weeks to upgrade.
