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

Very happy! I used this SIM card during my backpacking trip to Italy, Bulgaria, Greece, and France. I was very impressed with how the SIM card provided quality connectivity even in the more rural areas. I was a little worried that it wouldn’t work but it worked right away once my plane landed. The other person I was traveling with used another international travel plan the entire time and had much difficulty getting good connection but I had no problem. I would recommend this SIM card and I plan to use it again next time I’m in Europe!

My family had a plan to travel in London from June 19, so I ordered two 25G sim cards. I activated them on June 16 online when I was in USA following their instructions. On the airplane to London, I switched the ATT sim to this Three sim, on my two 5G unlocked android phones. In London Gatwick airport, I received messages to show all my two Three Sim cards are working now and get a UK phone number, great. 👍But when I checked these messages, they gave me a big Surprise 😔. I ordered two 25G Sim cards, as said in their ads, with unlimited talk and text, fast 5G network. One Sim had only 50 G data, need pay 10p per minute talk or per message. The other Sim had only 5G data with 3000 minutes for talking and 3000 text messages. What 😮? Ordered two same cards, eventually got different service packages? No sense 😲.The worst things are coming.1) During the trip from Gatwick airport to London eye, most of places only show one to two or zero bars. In the under-ground subway stations, definitely out of service.2) In the London eye area, signals were good but internet speed was slow 😔.3) CANNOT make a phone call to my daughter, who has a UK Three phone service. Both cards on different phones failed to call out my daughter. The voice told us that we didn't have enough money on it?!4) But we can call each other with the two phones. ????I wrote an email to customer service, asked for explanation and fixation, still waiting for their solutions. Based on my experience for only half day in London, I definitely not recommend it to my friends.

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.

We bought this card twice, once for a trip to Greece, where it worked very well, with good 4G coverage even in relatively small towns of Peloponnese, and then we bought it again for a trip to France, but there we found that while the calls and texts work, the data coverage is very poor over a large area, even in center of cities such as Caen. The phone will show "4G" on top but cannot really access any internet site. The coverage is very hit-and-miss, for example, in Chartres, which is a relatively large city, the 4G works only around the catheral, and not in places 1km away. This lack of coverage greatly reduces the value of this card for France.

Works well when in UK, 300 mins, texts, data, just swop out your SIM card and UK number comes up, can top up on line or in Three stores if need more. Very easy and good price

It was easy to install and uninstall. The only problem is that this SIM car did not work in one of the countries I visited. So, it would be nice to list all the 72 countries Three claimed to support.

Disappointing Experience with an International Prepaid SIM CardI recently had an incredibly frustrating experience with an international prepaid SIM card that I purchased for my trip to Europe and London. Unfortunately, my overall impression of the service was overwhelmingly negative, and I regretted my decision to rely on this particular SIM card provider.To begin with, the setup process seemed promising. The SIM card claimed to be easy to install, and it did live up to that expectation. However, my initial excitement quickly turned into disappointment when I realized the abysmal data speeds I was experiencing. It was nothing short of horrific, rendering the SIM card practically useless.Having bought the SIM card to stay connected during my travels, I found myself constantly struggling with slow or non-existent internet access. Basic tasks such as browsing the web, checking emails, or using messaging apps became a painstaking ordeal. It was incredibly frustrating to witness such subpar performance, especially considering the reliance we have on digital connectivity in this day and age.Ultimately, the poor speeds of the prepaid SIM card forced me to abandon it altogether and purchase a different one as soon as I arrived in Europe/London. Not only did this inconvenience waste my time and money, but it also left me feeling let down by the product's false promises.While I understand that network performance can vary depending on location and other factors, I expected a reliable and efficient service given the international nature of the SIM card. Unfortunately, it failed to deliver even the most basic level of connectivity, leaving me questioning the provider's claims of global coverage and high-speed data.In conclusion, my experience with this international prepaid SIM card was highly disappointing. Its initial ease of setup was overshadowed by the horrendously slow speeds, making it practically unusable. I would strongly advise others to explore alternative options when it comes to purchasing a prepaid SIM card for their international travels, as this particular provider failed to meet even the most basic expectations of reliable and efficient data connectivity.
