Works as advertised
I am finishing up a 17 day trip to Europe, where I used this Sim card during the entire trip. It certainly performed as advertised! I used it in a Nexus 6P android phone, which has the capability to work on a GSM cell network (most of Europe), as well as the CDMA network in the states, depending on the Sim card used. Couple minor hickups I'll mention later, but it provided excellent coverage and reasonable speed throughout Spain and Southern France. I followed the instructions on setting it up in the U.S., and it was good to go from there once I reached Europe. Something to note- don't initially set it up until your entire European visit is within the 30 day usage period. The 30 day clock starts when you initially set it up in the states. Couple additional notes and hickups. We traveled directly from the U.S. to Spain, and the 444 call for updates on balances (talking minutes, texts, and data) worked well. However, when we traveled through Andorra, and I no longer got any data connectivity. Cell service seemed to work, but no data available. Not sure that totally meets the advertisement of "works in every country in Europe", but our Andorra adventure lasted only for a stop for lunch, so it was not a big deal. Driving into France, it connected to the France cell network cleanly, but I still couldn't get data. Maybe it would have eventually connected for data, but I was impatient, and restarted my phone. Both cell and data connections were reinstated once the phone finished it's power up. Another slight hickup after that though, is that I could no longer get balance updates by dialing 444. It kept asking for a 16 digit Voucher number (which I didn't have), and would auto hang-up after I failed to enter a valid voucher number. Even after driving back into Spain later in the trip, it did not allow me to get my Sim balances, and continued to ask for a voucher #. Not sure if that was a ploy to get me to add minutes/data, or just a system malfunction, but it was only a minor annoyance for me because my phone keeps track of my data usage, and I could tell my data balances with my phone. Although I mainly bought the Sim card for data, I did have reason to make some phone calls within Europe, and it connected fine. Just remember to dial your number as though you are always calling from the UK, not the local country you happen to be in. Overall, it was a valuable addition to my trip accessories, and allowed me to research hotels/attractions/travel options as though I was in a big city in the U.S. It ended up being a good investment for my Europe trip!

No data
PrePaid Europe (UK THREE) sim card 12GB data+3000 minutes+3000 texts for 30 days with FREE ROAMING Seller travSIM GmbH Germany I had this activated May 13, 2023 while I was still in the USA. On this day, I received an SMS from Three saying I have 50 Gb of data (see screenshot) which was a surprise to me since the Amazon product listing said that data is just 12 Gb. On the same day, though, within minutes, Three also sent an SMS that said “You’ve run out of cash credit” (bottom portion of the screenshot). Huh?! There wasn’t supposed to be cash credit. This Amazon-sold product was supposed to just have data. In the USA, my phone connected to T-mobile. I had roaming on. There was no working cellular data which I didn’t have time to look at. I thought it would work better when I get to Europe. Fast forward to May 20, 2023. I’m in Vienna with no data. The top status bar of my iPhone shows 3AT 4G (often switches to 3G). There’s no cellular connectivity (data) - see screenshots. The messages in my phone are - Could not activate cellular data network. Safari cannot open the page because your iPhone is not connected to the internet. The Network Analyzer app shows the carrier is Three, network type is LTE but there’s no connectivity. I tried to send a text (BALANCE) to 50272 but it didn’t send. I got Failed Delivery If your travel date is on a weekend then you’re out of luck getting hold of TravSIM’s customer service. This SIM card is going back to Amazon. Fortunately, my 30-day return period has not run out yet. TravSIM, what are you doing selling a SIM card that doesn’t work outright as the product listing says it should? It’s a good thing I have a backup SIM card - Vegolink PRO. This one worked without a hitch. My iPhone status bar shows Magenta T LTE which I think means T-mobile.

The card works fine, but 3’s UK coverage is rubbish
The 5 stars are solely for the purchase/activation experience for this card. I don’t actually recommend this card at all, at least for use in the UK. The card I got was from a German reseller called TravSIM. To activate it you have to fill out a short form on their website and indicate the date you want the card activated. The printout that came with the card recommended choosing a date 2-3 days before the date of travel, which I found strange. I emailed them asking if it was really necessary to activate it this early and they responded, not really answering the question but saying I should choose the first date I will actually need to use the card as the activation date. I chose to activate it the day before I traveled. I got the activation confirmation about mid-day on the activation day, so I would recommend activating at least 24 hours in advance to ensure the card is useable when you arrive. Data and text messages worked immediately upon landing in London, but people were not able to call me using the SIM’s number. It turns out that in order to activate calling, you have to make at least one outgoing call first. The first call failed but gave me a recording stating calling would be activated within 5 minutes. A second call placed 2 minutes later went through and I was able to make/receive future calls without issue. Now the bad part: 3 has absolutely abysmal coverage in the UK. The second you walk into any building, the signal generally drops completely. Outdoor coverage is somewhat better, but there are still tons of dead spots. I’ve ended up mostly just using my US Mobile provider’s roaming coverage, which primarily uses the O2 or Vodafone networks, both of which have vastly better coverage. This card is cheap, but what good is 12gb of data if you never have service? I will definitely not buy a 3 SIM Card again and would recommend any other mobile provider in the UK, as they all appear to have much better coverage.

Product as per description. Easy to register and use.

The card only allowed user to use about 20MB instead of 10GB and it started asking for registration and and cash top up. It was totally disappointing and imagined you caught under the situations that you need to use the data plan to check information. This is totally not the good card to be used in Europe but i am not sure about uk.

I bought four of these SIMs for the family to use on two European vacations we have coming up this summer. They provide a decent voice and text allowance with a large data allowance and English web site and customer service. We plan to use the service in Scotland, England, Norway and Greece. I activated one of the SIMs here in the USA to verify it worked, which it did. I also registered on the Three web site which appears to continue the proud tradition of unbelievably horrible web sites established by Vodafone and Orange. At least it allows me to see something about the account status and perhaps contact customer service if I need to. Topping up needs to be done with either a credit card that has a UK address, or a voucher. So if you are not a UK person to top up you need to either have such a credit card, or know someone in the UK who will let you use their card, or get someone to buy you a voucher there. If you can make do with the initial loaded service credit (expires 30 days after first use) then you don't need to top up. I'm using an iPhone 6s and it did not require manual APN setup -- it just worked straight away after inserting the SIM. Currently roaming on AT&T's network in the US it gets HSPA+ service (not LTE) but using speedtest.net I get 8Mbits down 1 Mbit up which I think is pretty reasonable for International roaming. If I remember I will update this review once I've tried the service in Paris next week. Update: In France these SIMs worked nicely roaming initially on Orange, then mysteriously switching to Bouygues after a few days (we didn't change location). No LTE service of course but that was expected. Service via HSPA+ was certainly adequate.

I see there are a lot of bad reviews on this product which made me weary of buying it. But when we arrived in Greece I followed the instructions that came with it. I am in Italy now and it is still working flawlessly. Off to France and Spain next hopefully it continues to work. I think the issue a lot of people are having is that either their phone is not carrier unlocked, or they do not have data roaming option turned on. If your phone is not carrier unlocked this sim will not work at all. If you don’t have the data roaming option turned on, it will only work in the country that you activate the sim, and will not work in any other countries. Hope this helps people looking for a affordable option for roaming throughout Europe. There is a list on the Three Uk website of which countries their “Go Roam” roaming works in. Also the data connection is 4G speed only, not LTE but that wasn’t such a big deal.. it is fast enough to send emails and use navigation and Facebook and Instagram videos. I don’t think you would be able to watch Netflix or anything. Also I was able to setup a wifi hotspot so my wife could tether the connection to her phone. 12 GB data included in the package. I am 2 weeks in and only used 1.5 GB. Plenty of data for the 30 days that the card is valid.
