CORRECT DATA & MMS APN SETTINGS FOR SANSUNG S21 ANDROID

[cshenher1]

I've just spent about 3 hrs searching the correct APN settings for Android to make data & MMS work in the US.   Unfortunately, after Chatbot's recommendation did not work I tried about a half dozen other posted settings from here + internet searches and none worked.   

Does  someone have the current and correct settings to get this working please?

@cshenher1  Assuming you have data roaming turned on and have either a Canada/US plan or an appropriate roaming add-on with data (not just the US talk and text one), are you connecting to either AT&T or T-Mobile and selecting 4G/LTE instead of 5G?  5G doesn't work on AT&T so safest to start by trying 4G/LTE.  Some phones try to connect to Verizon but only AT&T and T-Mobile work for PM roaming.
