MMS issues after switching -Unlocked Samsung Galaxy S21 Ultra 5G
Please help! I've gone through the DIY MMS settings changes, restarted phone, etc. I have an unlocked Samsung Galaxy S21 Ultra. My sister can receive MMS from me, but my best friend can't.
Did you setup the device with your SIM in it.or with no SIM in it? Setting up the device without a SIM during the setup prevents the device from downloading all of the correct APN and IMS information.
