Duplicate Text Messages AT&T Note20

[Christie14]

Almost every text message I sent sends duplicate text messages. It's very annoying!

I also have issues where I don't receive group messages and can't send picture messages to certain people.

Overall very frustrating.  Had these types of problems with my Samsung Note 9 too!

Was told it's a system error nothing they can do

When did this started to happen? Do you have or had any ios device before?

Try changing the APN under network settings. Worked for me on ATT

[Christie14]

How do I do that? What do I change it to?

[Cyberwasp]

Settings

connections

mobile networks

access point names

hit add and enter the ATT settings below, save and select when done

one note, where it says apn type, those are commas, not periods. hard to se

[Christie14]

I also have the following options:

APN Roaming Protocol (Same options as APN protocol)

Turn APN on/off (Currently On)

Mobile Virtual Network Operator Type (None, SPN, IMSI, or GID - Currently on GID)

Mobile Virtual Network Operator Value (Currently 53FF)
