Both my husband and I have elderly parents, but his are not in the best of health. So, we want to be able to receive calls if it becomes necessary. (hoping it isn't). We have iphones and I'm with Verizon and husband is on AT&T. But his is a work phone, so his company will pay for any calls.
What do I need to tell Verizon about international calls, texts, etc. I hope to not make calls other than using What's App. But I'll probably want to text our daughters back in the States.
