Hi. My unlocked unbranded s9 plus on latest firmware will not roam to foreign networks while travelling. My note 9 will and if I switch sim cards, the sim from the note 9 to the s9 it still will not allow roaming. There are no other issues with the s9 so this error is strange. Any help would be great thanks.

I had exactly same issue with my Samsung S9 plus. I was at USA on roaming (had Airtel postpaid connection from India, roaming plan was activated.)
I had no issue with incoming and data while roaming, but the outgoing wasn't working. I tried several solution like rest network setting, manually selecting network operator (AT&T in my case), diabling VOLTE etc.... nothing worked.
Note: My SIM was working on other Handsets (non Samsung), and Other working SIm had same issue when I plugged them in. This means, issue is not woth network or service provider but with handset.
One fine day, I tried putting my SIM to SIM-SLOT#2....and wondered...it worked.
I don't know the root cause....but here is the solution.... PUT your SIM into SIM#2 slot. (No other setting change needed).
Let me /others know if it worked for others too.
