We will be traveling to Iceland and the Baltic region (including Norway, Sweden, Denmark, and Germany) next month, and I will need a virtual sim (sorry that "sim" is not capitalized, as the system thinks I am shouting and will not post if capitalized) for my phone. My use will be very light, such as occasionally checking email, looking something up on the Web, etc.
I am wondering about what the easiest-to-install sim might be. The last time I traveled to Europe, I was able to successfully install a sim, but it was very complicated, and I could not be sure that it worked until I arrived, which was rather stressful. I am willing to trade cost for something simple, straightforward, and easy to install.
If there are any recommendations by non-technical people, then I would greatly appreciate the pointers.
