UK SIM Card 30Days 30GB / Europe SIM Card 30Days 12GB, Unlimited Local Calls and SMS, Applicable to 72 Countries, Support 4G/5G Operating Networks, Easy Activation & 24/7 Whatsapp Support

I followed the instructions and had no problem using this SIM for 3 weeks in Scotland. The data worked with no interruptions or issues, except for a couple of times when I was in very crowded places (it was during the summer festival season). My friends with pre-paid SIMs by other providers actually had a much worse service than me in the same locations. I was unable to use the card in Turkey while the coverage was still on but it's my bad for not reading the list of covered countries carefully. The customer service answered my concern quickly and took the time to look into the issue and explain the reason to me via WhatsApp. I had a transfer in Italy afterwards and the data worked fine there. I did not use this card for calls, but texts seemed working fine, I just mostly use messengers when I travel. I will definitely buy it again if I go to Europe!

Amazon warned me, a lot of people return this item. I didn't listen. A bad review told me a customer had one not work straight out of the box. I didn't listen, instead I bought an extra for my wife and myself. After install I couldn't make calls until I added a new plan$$. When I crossed the border into N. Ireland it quit working. Evidently the 1% of the UK that isn't covered is the M1 highway. Time for purchase a new plan$$. How do you order a new plan without a working phone? Found a convenience store, bought 2 Vodafone cards and the clerk kindly used their phone to get my wife and I set up. Vodafone card was problem free. Worked in N. Ireland and the Republic of Ireland from Giants Causeway and back to Dublin. No issues crossing the border. I didn't listen. I hope you listen, don't buy UK3. I can't imagine how difficult the ordeal would have been if I wasn't English speaking or the store clerks didn't kindly help with their time and their phone.

The key is to order early and install a couple of days before heading to the UK. I received two SIM cards on Monday before heading to London on Wednesday. We have eSIMs for our regular service so I was able to just insert these SIM cards into our iPhones and add them as a second line. By following the instructions given, set up was easy. The day after starting the process, I got a series of texts from 3 that my service was up and running, but my wife only got part of a messages, so I was a bit nervous. When we landed in Heathrow, my wife's data didn't immediately work so I contacted the vendor. They responded within an hour, but by then her data was working fine. So, by the time we left Heathrow until today three and a half weeks later, we have had no problems at all. And the 30 GB that we got was far more than needed. I only used about 10 GB on mine and my wife's a bit less. Highly recommend the service.

from Glenn H's review on April 23. That will ease the setup experience. Overall, the card did what the company said it would do, for the most part. I activated it and installed it before I left and had my British number and was able to give the number to family and friends. It worked in Great Britain and it worked in Romania. Few problems with reception on calls. Few wifi dead spots. Just some glitches on a call in a Manchester airport hotel and some loss of wifi in the Underground. I was NOT able to call from Britain to Romania without "topping off." I elected not to do that. But you will not be able to call from Britain to there, at least, without loading up. Everything else was fine. My mobile data even worked in the U.S. (But read thoroughly, you will not be able to make calls or send texts to the U.S.). Good for letting people reach you but not the ideal solution if you want to call or text out of your area.

Purchased this in the U.S. for use in the U.K. I was able to register this mostly ok (took 2 times). The data worked fine, but I wasn't able to use any phone or SMS services while there. I tried in vain to get support to help, but gave up after spending too much time trying to figure out why any local phone call got me an error saying I needed to top up. It appears that although phone and SMS are "unlimited", you need to pay for minutes, which doesn't really make any sense to me.

I was very satisfied with this product!! Last month, I traveled to Europe for one month and bought this product ahead. I followed all the instructions that were clear and comprehensive. Once in Europe, I traveled to France, Belgium, Luxembourg, Germany and each time, I could get and send text messages, phone calls and check my emails and apps on my iPhone. At any time! I have never had a problem. Every time, I was crossing a country border, it would alert me and the phone calls/messages would resume without fail. I am not very knowledgeable in SIM cards but was SUPER happy with this product and will definitely buy it for my future travels.
