We didn't set up cell service at all, just turned on wifi calling and used Messenger and Line for most of our communications. Verizon does offer pay-as-you-go service in addition to the flat-rate $10/day or $100/mo international plans, and for us it was cheaper to pay the $0.25 per text and $2ish per minute for voice for the very limited bit we used our devices than it would have been to add a comprehensive international plan. But those rates and the availability of wifi both vary by country, so the destination could make a difference in how best to handle communication.
