I went on a month-long trip to Europe this June and found several surprises on my Verizon bill since.
I chose to have the international plan on my phone as I did not want to set up a forwarding service for my phone number. I know that you can get a free Google phone number that can receive calls and texts via the internet but I just didn't want to mess with that. Knowing that I may need to verify some transactions for my bank, I knew I would want to at least have texting.
I have learned several things since that I wish I had known beforehand...
1. The international monthly plan is $100 on top of your regular plan. So for me, that was $100 plus $50 (times 3 as there were three of us with Verizon on this trip).
2. The international monthly plan does not cover any calls made from the states. (I had a cancelled flight so I had to change a reservation in London so I called thinking that I would be covered as I was already on the international plan. Wrong.)
3. Service was frequently not fantastic. We were primarily in the big cities- London, Paris, Rome, Florence, and Venice, but we had unreliable service often. When you are using online maps to navigate, it is frustrating when you can't get a signal. (We knew the underground and subway would interfere with service so we had maps downloaded but we frequently couldn't get signals when we were up on the streets either.) Every phone seemed to respond differently as well. It was like playing roulette to see which phone would get service and when. Most of the time our kids without Verizon won.
4. If you choose to use an e-sim, as one of us tried, research how to stop Verizon from automatically connecting anyway. (Our kids are not on Verizon and we got e-sim plans for them and their service was better than ours with no hiccups.)
What I have learned for future travels.
1. Any trips over 10 days are worth setting up the Google phone number to forward all calls/texts to and just get an e-sim plan.
2. Figure out how to stop Verizon plan from interfering with that e-sim plan. (I know that starts with turning off the travel pass availability.)
I hope this helps others in their quest for a connected adventure.
