What phone do you have?
What plan are you on?
Does your plan include data, or just talk & text?
My wife has a Moto G4 and I just bought a Moto G7. When we are at my in laws home I cannot even text or make any calls unless I jump on a WI FI network. My wife can with her older phone. Is there a way to check if the phones are trying to access a different cell tower or is there something else that would make the G4 connect and not my G7?
