What phone do you have?
What plan are you on?
Does your plan include data, or just talk & text?
Just talk and text
The problem of not being able to text, when not on WiFi has been going on for years. Was sent a different sim card, but that didn’t work. Although I do not have a data plan, I have mobile data turned on.
Once in a while I can text when I’m out and about, and not using a WiFi signal. And like yesterday, when I could not text, I was able to make a phone call to the same number I was trying to text to.
I thought texting took less of a signal than calling.
