Re: Galaxy S9 ATT unlocked?

JUMP TO SOLUTION

You can unlock your phone after you bought it from ATT. I have read how to do this here, and it have been very helpful.

Just use Att.com/deviceunlock to request a code. This works for customers and non-customers. If you use an unlock service you can try swiftunlocks or attunlocker.us to buy a code for your Samsung Galaxy

Call dropping

JUMP TO SOLUTION

Calls will be dropped. More than 10 plus calls you will miss daily.

I Brought s9 plus sm-g965u  from Att with fully paid. 

I unlocked it using ATT portal.

 

 

Issue starts now, once i unlocked i changed my network to Tmobile. 

 

After few weeks, daily few calls  are dropped and goes to voicemail. (Dont tell network issues for T mobile) 

 

I am facing nearly 10 plus daily calls are dropped. I tried reset network settings. Factory reset. Change the sim. None of them worked

 

There are lot of people facing it 

With this device model

https://support.t-mobile.com/thread/138538

 

No technician knows whats going on. 

Some says maybe problem with sim, signal most stupid answer is maybe you put Tmobile sim in att device. When i say its unlocked  no response. 

 

I tried to contact samsung they says our technician will solve it

 

If ATT PEOPLE ARE HERE OR TMOBILE.. SAMSUNG PEOPLE TRY TO RESOLVE IT. 

 

 

 

WHY CANT I RETURN THIS MALFUNCTION DEVICE AFTER USING 2 MONTHS.....SAMSUNG?  EVENTHOUGH IT HAS ONE YEAR WARRANTY? 

 

 

DONT EVER BUY ATT PHONES....

So i bought a Att S9+ unlocked it and went to verizon. Immediately when the sim car is added the builds will update to a Verizon build.

All models of S9 carrier and unlocked have the same radios. If you are having issues with your phone check the APN as you may have to adjust the settings.

It's best to purchase thru your carrier than thru samsung  (to get an unlocked device)? Trying to best the Note 8 at the cheapest rate possible.

Carrier/sim Unlocked is NOT the same as getting a Truley unlocked Phone from Samsung..Samsung Unlocked has all Radios in it and has No carrier bloatware..
