Hello everyone,

I will be driving around Europe sometime next year. I would like to use some smartphone navigation apps (e.g., Google Maps and Waze), but unfortunately, from my experience, data roaming charges can drain my pre-paid credits quickly (e.g., Germany to Switzerland).

My current solution is to stop before crossing a border, turn off the phone, and switch SIM cards. I do know about dual SIM smartphones, but it also requires turning off the phone and inserting a new SIM card especially when crossing multiple borders.

I have seen Global SIM cards, and it looks promising. However, most of the reviews that I've read seem to point to such international SIMs do not provide the coverage as advertised. As a traveler, have you used such a SIM card? If so, which one has lived up to your expectations by far?

Thanks!
