  • Worked in Colombia
Style: 2) 10 GB
This is basically a prepaid data-only SIM card from UK's Three. Upon receiving the SIM card prior to my trip to Colombia from the US, I contacted the seller to activate the SIM card, and it worked in the US (also received a text message from UK's Three). The data also worked fine when I landed in Colombia, but the network speed was pretty slow and spotty (4G, around 1 Mbps on my unlocked iPhone 12). The amount of data (10GB) was more than enough for my short visit, and it continuously worked in the US for the remainder of the thirty days. Interestingly, I created my account on the Three UK website using the SIM card information I had after the trip, and it looks like I could renew the data plan if I wanted for only £10 per month. And I will even get 20GB if auto renewed every month including UK's unlimited minutes and texts. Overall, I was happy I had the data connection during the trip, and I think it's a great deal if I kept the SIM active and used it as a data-only plan in the US and 71 other countries, if only I could visit so many in the future. ... show more

  • Calls and text severely limited!! & cannot contact any US phone number
Style: 2) 10 GB
Despite being one of the advertised 71 countries, this sim did not work to contact ANY United States number via text or call within the US before I left, as well as outside of the US when I was in Europe. The whole point was to be able to stay in contact and I had to download a wifi messaging app. Super frustrating. Furthermore somehow after 30minutes of calls to a euro number, I got a notice that my card was out of credit and needed to be topped up?! It would no longer let me send or receive texts or make calls. Not the “unlimited” that was advertised! So disappointed!! The only star is for ease of installation and the fact that the data at least worked. I never came close to the limit so I can’t comment if it was the full advertised 10gb or not, but call and text was fully false advertising and I would not recommend to purchase this. ... show more

  • Works well and is economical
Style: 2) 10 GB
In the past I have bought a sim card at the airport in whatever country I was visiting. Prices and amount of data were all over the place, plus the service was always in the local language, making texts from the supplier difficult or impossible to understand. I bought this item from Amazon this fall and used it for a 17-day trip to Belgium and France. It worked in each country and during a transfer in Dublin. No problems other than it took an hour or more for the service to be re-established after crossing a border. I put it in my phone the day before I left, followed directions, and the next morning I was in business. Instructions are clear. I will buy this for my next trip if it is available. In addition to using email and browser, I use it with Google Maps and similar apps, and it was always available. (I did download local maps in U.S. before I left, just in case.) Like many or most of these sim cards, it doesn't give you actual telephone service, as far as I can tell, but you can use Skype to get around that. I usually just ask a local, e.g., a hotel clerk, to make a call if needed. ... show more

  • The features advertised do not work while you travel, DO NOT BUY THIS CARD
I bought this SIM card for European travel. It advertised 36GB of data for one month with an option to top up. The Three company fails to mention on Amazon that you can add the money ONLY if you have a UK based credit card. With a UK-registered address. I am a US customer with a US issued credit card. There is no way to pay with a non-UK credit card on the web site. Contacted customer service. I spent two long sessions with customer support, it turned out there is no way to add money to your sim card without a UK credit card (and a UK address). "I'm afraid you won't be able to use any card to top-up. Only Uk registered card." - was the response from my chat with the customer service. And, also, out of those 36GB data the company promises - you can use only 12GB, the remaining 24 GB require a 0.5 pence per MB charge which - guess what? - you can't pay if you don't have a UK credit card and a UK address!! That certainly feels like a carefully disguised scam for non-UK customers to me. If you sell SIM cards on Amazon to US customers without a way to such customers to even use the promised 36GB, there is something very wrong with the company and its product. DO NOT BUY THIS CARD unless you are a UK customer with a UK credit card and address. I just wasted my money on this product. ... show more

  • Easy to use, works well in some areas - not the best provider for Sicily
Style: 2) 10 GB
I bought this SIM for one of our two phones so I would have a working phone upon landing in Italy, although I knew Tre did not have the most extensive coverage in Sicily (the Wind network). Follow instructions to request activation of the SIM online before you try to use it. I didn't have time to test in the US before we left, but during our layover in London I put it in my phone and turned it on, it worked immediately. It also worked perfectly once we landed in Rome. I didn't have to change any settings or select a network, it just connected automatically. In Italy, we bought a Vodafone SIM for our other phone. Vodafone's network is better in Sicily, and there were times that SIM worked while the Tre didn't, or was much slower. The Vodafone also allowed tethering, so sometimes I tethered to it when Tre wasn't working for me. This SIM worked fine in Rome, Palermo and Trapani. Not at all once we drove south of Trapani, until we got to Ragusa where it started working again. Generally worked on the east coast of Sicily, but sometimes spotty/slow and the Vodafone was more reliable. I would buy this again if I was going to use it in areas where it has a strong network. It was great to have a working phone when we landed, especially since it was late and I didn't want to have to deal with buying a SIM at the airport. ... show more
