4G S8 to be disconnected with 3G shutdown - here is what you can do

If you own a Samsung S8 starting with model number G955U or G950U, and you have received a text/letter from AT&T saying they will disconnect you in February for using a 3G phone, take note.

FIRST: Your phone is 4G and should is supported. Samsung has confirmed this for me and showed me an AT&T web page that doubly confirms it (see

SECOND: AT&T is ignoring complaints about unilaterally disconnecting 4G phones under the guise of dropping 3G service. Some are speculating that AT&T is railroading you into upgrading your phone when it is not necessary.

THIRD: You should make your concerns heard by the following interested parties:

SAMSUNG: They should be concerned that AT&T is misinforming customers about Samsung product capabilities. Here is a shortcut to voicing your concern

FTC: Since AT&T is providing customers fraudulent information, telling the Federal Trade Commission about it will get a response. Visit

FCC: Since AT&T rents the public airwaves, and since the FCC has many consumer protection rules, they too should be made aware at

Be sure to note that (a) you have a 4G phone, (b) AT&T is incorrectly identifying it as 3G and (c) is preparing to kill your service in February (and maybe scaring you into upgrading).

FYI that Samsung just rolled out a software update at the end of April that seems to have fixed this problem for me! I now have LTE service and can make calls/use data when not connected to wifi.

The problem is that some s8 models that are 4 g capable use 3g and 4g simultaneously.  There’s no way to turn that feature off.  So any of those s8 models will not work.  Only the specific ATT model with volte will work after 3g shutdown

It is not just 4G capable. It must be 4G LTE for VoLTE. Basically, the 4G without the LTE is essentially enhanced 3G.

AT&T has a strict certification list. A phone not being on it means either it failed certification so did not meet all technical requirements or it wasn't submitted for certification in the first place.

AT&T has no obligation to let everyone try to use all phones in existance just because it 'might' or "should" (according to individual's opinion) work. If it doesn't pass the test, or didn't go through the test, get a different phone or change carriers.
