What phone do you have?
What plan are you on?
Does your plan include data, or just talk & text?
My daughter’s phone is a Moto E and she is on the talk and text plan. No data.
Her phone will receive texts from everyone but me. She receives my texts if I turn the wifi on. I tried deleting my contact info and re adding my self but it is still not working. She can text me but she does not get my response.
