iPhone XS Dual SIM - SMS sent from ATT SIM number, not the number I specified!
I have an iPhone XS with a EU carrier physical SIM and ATT eSIM.
For the most part everything works as expected. However, every so often when I send an SMS and specifiy to use the EU sim for the message, I get an error from ATT that the SMS cannot be delivered, incorrectly formatted number, etc. when I specifically told the phone to use the EU sim.
It seems as if ATT for some reason is hijacking some of my SMS texts and trying to send them, even though I've told the phone to use the EU sim.
Has anyone else seen this, and more importantly, know of a fix? It's maddening, as I cannot send texts to friends and business people. It only seems to happen here and there at random, not always, but once a number/contact starts getting mixed up, it seems almost impossible to fix.
