According to internal T-Mobile documents obtained and verified byAndroid Police, the company plans to drop mobile data pipe 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-Mobiles internal list:

Phones:

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

ZTE ZMax

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 carriers internet your rig originally uses.

T-Mobile and MetroPCS devices will lose all data pipe support starting January 29, while Sprint devices will lose T-Mobile roaming connectivity but can still use Sprints legacy 3G data pipe until its shuttered in 2023.

Its 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 Polices 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.

The short notice is inconvenient, but wed recommend users upgrade from any of the smartphones listed above even if T-Mobile wasnt dropping support.

Not only are new phones faster and packed with better features and cameras, they also receive regular security patches that older phones do not.

If price is an issue, look into mid-range devices like the Pixel 4a and 5a, or Samsungs Galaxy A51.

As long as the phone is still supported by its manufacturer, itll be a huge jump in performance and security, and you could buy one for a lot less than a new flagship handset.
