iPhone not receiving texts
In my town there is no cell phone service available. I can connect to wifi in my home in order to make or receive calls or to send or receive texts to other iPhone users. Recently, however, my phone is no longer receiving either texts from users of android phones or texts from any automated systems (for example any 2-step security ID system). These texts will arrive on my phone once I have gone to another location that has cell phone coverage. This wasn't the case in the past, and I didn't change any of my settings. Can someone help me figure out how to fix this? Now that many sites require 2-step security ID texts this is becoming increasingly problematic.
Thank you.
