We just got a new phone for my son. It is an iPhone xr. Both my husband and I use Samsungs. We added my son to my icloud account as a family member and so he has his own apple ID. He can send and receive texts with other Apple products, but can't with androids. He uses the messages app that came with the iphone. I have made sure that the settings are set so that he can receive and SMS and MMS. But no luck at all. I am so frustrated. He needs to be able to send and receive normal texts . . .
