Three Mobile Pay As You Go Data SIM

I took a 3 week trip to Europe in June 2017 and this card was great to have. I have an unlocked phone (Asus) using T-Mobile in the USA. I didn't want to pay roaming charge on my trip so I got this SIM card. Because this is 3GB of data (only, no voice or text) and last for 3 months, I tested it out in the US before my trip. It worked, and was plug and play (just put the SIM card into the phone and it worked, I was able to get my Whatsapp as well as surf the internet and my apps worked). It is only 3G in all countries, except for 4G in the UK...which is fine with me. The coverage was spotty sometimes (similar/relative to my T-Mobile coverage in the US), but again, for the price paid, it was more than adequate most of the time. It worked for my trip to UK, Germany, Ireland, Denmark, Poland, Estonia, Sweden. The only country it didn't work was in Russia. I was on a Baltic cruise ship and it even worked on the ship quite a bit as we were near the coast/land a lot of the time so it was able to pick up signal from shore and especially when we were in the ports (a big plus since internet on cruise ships are so expensive). So if you are going to travel to Europe, you should get this...can't beat the price for what you get!
