No texts coming through to verify phone number on Apple Account
Traveling out of the country, I used an esim. iMessage stopped working and was showing me only my email address in my Apple account. I try to add the phone number but it wants me to verify it via text, which I can't get because iMessage doesn't work! I can't figure out what happened and how to fix it.
