Bests & Worsts Reviews from Amazon

Bought these for two Verizon iPhone 7s. They worked like a Charm and were way less expensive than adding a few days of International to my Verizon. When we arrived in Heathrow, we made our way to ground transport and installed the sims. All we did was turn the phone off, use a paperclip to pop out the Verizon SIM, and then pop in the Three SIM. We powered the phone back on, and within a minute we had received a text stating the SIM was initializing, and shortly after a text asking us to restart the phone. Upon restarting, a text arrived stating everything was working. It was! The SIM does come with Tethering, but I could not figure out how to tether over WIFI even though my iPad could see the phone. I could select the phone on my iPad, but would get a connection failed error instead of the password request. I was, however, able to get the tethering working over Bluetooth for the odd occasion when I needed my iPad and did not have wifi. I have no experience with tethering, so was unsure what was going on. Over the space of 17 days of normal use (for me) I think I got through about 5GB of data. I hardly used any phone minutes or texts because most of the time I was using Apple Messages. Interestingly, when I got back to Minneapolis and pulled the phone out once we had cleared customs I noticed that the phone was picking up T-Mobile and that a message had come in stating I could use the sim "internationally" and what Three Mobile's rates were. I did not bother testing it because I just popped out the Three Mobile SIM, Popped in my Verizon SIM, restarted the phone and I was instantly back to Verizon. I did see these SIMS in a SIM dispenser in the Heathrow Central Bus Station and noticed the prices were not unreasonable over there, but I calculated that I did save buying them before leaving. The SIM dispenser had a lot of choices from different mobile companies, but the Three Mobile SIM definitely seemed like the best value if Data is important to you. Overall, this was a great experience and I would recommend this SIM to anyone with an unlocked phone. Verizon is always unlocked, but I do not know about other US mobile companies. Apparently, you can check by taking the sim out and looking whether your carrier is still listed in the Cellular preference, but you are better off reading about that on Google!
