  • It worked all over the UK for my son!
Model: 30 Days - 20GB
My son just got home from a 2 week trip to Europe. He used this particular SIM for the first leg of his trip, which was in the UK. We did activate it before he went - and honestly that was super easy. You just need to confirm the dates of use and a few more details, and that's it. He put it in when he arrived, and it gave him zero issues. He was using a global GSM phone, by the way, so I can't speak to specific phone types or country specific GSM bands, etc. He had no issue using it for data voice calls (like WhatsApp, Telegram), and seems to stay connected everywhere he went. Speed was acceptable, and as I already said, easy to setup. This card did come with a phone number - but I don't think he used that feature at all - just the data aspect of the card. He's not a gamer, heavy video watcher, etc. So, I can't really comment on the real speeds and such, but for him he was able to take photos and videos and have them upload to Google Photos without delay or issue, use web-apps of all sorts, and multiple messaging and call applications. All of them seemed to work. The way you receive this is a bit tricky - not labeled super well - but easy enough to activate and get started with. Just use the QR code on the the little page of instructions and you'll be off and running. I was honestly surprised at how easy this was for him to use - he's not much of a techie at all. I highly recommend for your short trips to the UK - a great value for the money and something you can check off your list before you go! ... show more

  • "3" SIM worked well in Lonon and the US
Model: 30 Days - 20GB
Setting up the "3" SIM didn't involve registration or jumping through any hoops, but this could because the phone had been used with a temporary "3" SIM before. Data connection was good in central London (Knightsbridge and South Ken). Surprisingly the data also works back in the US where it switches between an AT&T connection at JFK and T-Mobil in my home state. The connections in the US are maybe a little slower/lower priority. ... show more

  • A Godsend for Travellers to the UK
Model: 30 Days - Unlimited
I am relatively new to the world of eSIMs, and did a lot of research prior to ordering this. I was pleased to find that an eSIM allows the user to keep his or her phone number. I travel to the UK at least once a year. Usually I inform T-Mobile beforehand, and add a plan to keep phone calls and data usage at their cheapest rates while I am there. With this eSIM, I will not have to. This product is a pamphlet with a QR code, in an envelope. I first checked to make sure that my Samsung Galaxy S23 even accepts eSIMs. It does. The instructions are to: 1) Access the SIM Card Manager by opening the Settings app, navigating to Connections, and selecting the SIM card manager; 2) 2. Add a Mobile Plan (eSIM) by tapping on 'Add mobile plan.' Options to add an eSIM will then be presented. 3) Select 'Add using QR code' and then scan the code with the phone's camera. 4) Add the provided activation code (it is included on the pamphlet). Given that once activated, the number of days begins to run, I would not activate this until the day before the trip. I will report when I learn any new information. My next trip to the UK is in the next few months, but I wanted to leave a review now, to relay my findings. I will update if anything changes. ... show more

  • Effortless Connectivity Across the UK – Unlimited Data with Zero Hassle
Model: eSIM 30 Days - Unlimited
The travSIM UK eSIM is a game-changer for travelers needing unlimited data without the trouble of switching physical SIM cards. I activated it instantly by scanning the QR code before landing, and it worked immediately upon arrival in London. Coverage was reliable and fast across England, Scotland, and Wales — consistent 4G/5G speeds even in rural areas. Streaming, navigation, social media, and video calls all ran smoothly with no throttling noticeable throughout the 30-day use. It’s a data-only eSIM, so for calls/texts I used apps like WhatsApp and Signal without any issues. If you’re traveling for work, school, or tourism in the UK and want a worry-free, truly unlimited data experience, this eSIM is an excellent choice. No roaming charges, no SIM swapping — just solid, uninterrupted connectivity. ... show more

  • Great travel option
Model: 30 Days - 150GB
I had a member of my family who had to travel to the UK with only a few weeks’ notice. We were excited to find this travel SIM card to make it possible for him to remain in touch without having to figure out how to travel with a US sim. The trip got postponed, so we did not get to use it, but we are holding onto it since we expect the need to travel to the UK to happen again. I would have preferred to use the SIM card before reviewing, but there is a short period during which these reviews must be made. We look forward to having the opportunity to use it in the future and are encouraged by the positive reviews from others who have used it during travel. ... show more

  • Better Than Quite A Few Carriers Used Previously
Model: eSIM 30 Days - 150GB
Good overall. Price, ease of activation and porting though you have to activate the phone first and get a new number. Afterward you will fill out a form in your acct for porting. Took about 15 minutes to switch over from Spectrum Mobile. The website is user friendly and instruction straight forward. The account is also easy to navigate and they have a variety of packages for every type of users with good prices. Found a plan for $7 a month for a light use phone. Will see how the signal coverage is after some traveling. ... show more

  • Easy and worked perfectly
Model: eSIM 30 Days - 150GB
I used this on a recent trip to London, and provisioning and setup could not have been any easier. I ran into a minor hiccup (my fault, I missed a step) and an email to support was answered promptly and solved the issue. Traveling from the US on a T-Mobile plan limits you in a lot of countries to about 256k of bandwidth, which is near useless anymore. With this sim, I’m seeing speeds ranging from 50Mb/sec to well over that, depending on my location, which is just fantastic. ... show more
