Ref new AT&T Plans (port in from TMobile)
Coming from Tmobile carrier unlocked galaxy S9 to AT&T $65 unlimited plan ($45 with auto pay). Lots of questions but want to be fully informed and feel many people can benefit from these answers! Please note these questions are specific to working with an unlocked tmobile device.
-Will the following features work and are there steps to provision my existing tmobile branded S9 that will be unlocked:
1. HD voice calling
2. Voice over LTE (VoLTE)
3. WIFI calling
4. Visual voice mail
-How do I get future Samsung updates? Since the phone was once developed for Tmobile
-Is phone flashed at AT&T store for AT&T features?
-Does prepaid have an account management app?
-On the $65 plan (45 with auto pay) is data subject to prioritization at ALL times or just after 22GB. And is it just slowed occassionally at times of congestion?
-Multi line discount:
If line 1 is $45 and line 2 is $35... say I one day decide to move line 2 to another carrier... does line 1 keep the $20 autopay discount and remain billedthe same monthly($45 total)?

Hello @ant1171984,
We can definitely answer these questions for you.
Unfortunately, there's no guarantee that those features will work properly on your cell phone because it isn't an AT&T branded device.
You may need to contact the original carrier, or manufacturer, to download the latest software updates if your device is not AT&T branded as well.
A cell phone that isn't AT&T branded cannot be flashed with AT&T features at one of our store locations.
You can use the myAT&T app to manage your AT&T PREPAID account. The app can be downloaded free of charge from the device App store, or by texting App to 8758.
All data usage may be temporarily slowed during times of network congestion on our $65 AT&T PREPAID plan.
Once a member of an AT&T PREPAID Multi-Line account is removed from the account, the account owner will no longer receive a Multi-Line discount for that member.
Please let us know if you have any further questions or concerns.
Sean, AT&T Community Specialist
