New PrePaid Europe SIM Card 16GB Data Unlimited Minutes/Texts for 30 Days with Free Roaming/USE in 71 Destinations Including Europe, South America and Australia (ThreeAIO16GB)

I've purchased this SIM most recently for a three week trip to Peru in March/April (and in 2019 for a trip to Germany and France.) I've found them to be an excellent, economical solution. This past trip it's worked seamlessly with the networks in Lima, Cusco, and in smaller towns such as Chincha and Ollantaytambo.It's not perfect but the good far outweighs any issues. I purchased from TravSIM because unlike another retailer, it's my understanding that if needed I can purchase additional data via their website using a US credit card (by contrast the UK Three site only allows payment in British pounds.) The minor downside to purchasing through TravSIM is that activation took a few hours, about four hours, as I recall (I think they advise it may take up to 24 hours). Also, when activating on their website (which I did in the US), you need to state both the start and end date yourself. They appear to be on German time so if, for example, you specify activating 11 p.m. the same day, the site advises that you can't activate for a date that has already passed.Once activated, I tried the SIM in the US and downloaded the UK Three Pay as You Go app (I'm using an Android 11 phone.) It takes a few minutes to find the signal. There have been comments here stating you won't receive the full data if it's not being used in the UK. This was not my experience. The app showed the whole 25 GB as available. (However, when my wife tried using the app on her phone, it never showed the available data. But she had no trouble using the data.) Initially, I'd emailed TravSIM about how much data I'd actually receive, and they never comprehended my concern and eventually stopped responding.Having a functional phone is a necessity for me, as there are matters I need to stay on top of back home in the US. I believe the included minutes are not available for use outside the UK, but with the included data, I used Google Voice to make/receive free calls/texts from the US, Skype prepaid to make local calls in Peru and WhatsApp for additional communication (LATAM Airlines uses it for communication, for example.)Overall, this SIM has repeatedly served my needs very well.

Installed the sim on my phone as it say on package in US prior to leave the country and it worked, so I Removed and went back to my network. When arrived abroad , installed the sim back in , and it worked for 3 hrs until quit. I recognize signal but it doesn't work, it ask to register, and we can't register an three account without a phone number. Tried an online chat with three , which they didnt want to help. Waste of money, don't buy this sim card. I will request a return of my money.

I just completed a vacation through Czech Republic, Hungary, Austria, Germany, and the Netherlands. I never had any issues with the sim card working in any of those regions. As stated in the product description, it will not make calls or allow texts back to the U.S. without extra charge - nor will it allow access to those numbers even if the phone with American numbers is in Europe. However, I did find that I could circumvent that issue by hotspotting my telephone to my wife's Samsung Galaxy 10 plus (which had the sim card). While connected through the mobile hotspot, my phone was able to act completely as if I were back in the U.S. including allowing calls and texts through wifi. During the trip, we primarily did basic searches and used google maps extensively - the 25 GB was well in excess of what we needed for the 3 weeks that we were there. It was well worth having for the peace of mind wile traveling.

I was expecting to get a sim card that would be through three, but what I got was one using the three network and serviced by travSIM. This was NOT mentioned in the listing. If this is expected the listing should be updated.I got three cards for my family, one didn't work, one sent me an array of crazy text messages that I was about of data and then gave me 50Gb, and the third seemed fine.I tried getting in touch with customer service about the one that didn't work and they didn't respond.I would just go to a mobile shop when traveling and buy and install a sim card directly from a retailer.

We bought this for a cruise in Italy, Greece, Croatia, and also for flight connections in Germany and France. It worked great with high speed data everywhere and calls too.Before I left home in the US I plugged in the SIM card to test it. It immediately connected to the AT&T network and data worked fine. However, I could not call the test number in the UK for calling. So I was worried if it would work in Europe, and sent an email to the seller UK Sims. They quickly responded that it would work fine in Europe and calling from the US only works if you connect via T-Mobile, not AT&T. So I was still a bit worried, but when I arrived in Europe it worked fine.Great price for much more data than I could possibly use in 2 weeks of travel. Will happily buy another SIM card from this seller for my next trip.
