I’m traveling to Ireland and the U.K. twice over the next several months. My iPhone 7 is on a Cricket plan. I only see international options available for data through Cricket if traveling to Canada or Mexico. Can anyone recommend a way I could use my phone while not on wifi? I anticipate I’d like to have access to online maps and Yelp while walking around. I figured there might be a way I could swap a SIM card, but I’m not sure where to look. I’ve seen things on eBay but would prefer to get guidance before buying anything. And if I did swap the SIM card, is it a plug-and-play kind of thing?
