I'm planning on taking a solo trip to the UK and France in a few weeks. Since I'll be solo and seeing some of the country side, I'd prefer to have phone service of some kind.
I currently have a Tmobile iPhone 7, but I may be upgrading for an iPhone XR right before I go. I've considered both buying a SIM card and paying for a personal WiFi hotspot.
Does anyone have any experience with this? Is a SIM card worth it, or a wifi hotspot? Will my tmobile phone even be compatible with a new SIM card?
