10GB Add-on

So, this prepaid SIM card makes the most sense for those who are traveling to one or more various European countries in the 30 day period. Having the data part also work in the US (uses T-Mobile network) is a great bonus with a SIM from a company that operates first in English and doesn't require a lot of registration that is otherwise common throughout the world. In most countries on 3's GoRoam program, you can get LTE coverage, but some countries specifically have only 3G coverage negotiated. The data isn't super fast, but very usable and better than most public WiFi networks which is the alternative. However, I also found having a European phone number for voice and native texting very valuable especially if you want to use ridesharing or taxi services. Having this SIM definitely made my trip much easier to manage. In the UK, 3's network is definitely less overbuilt than O2 or Vodafone, but not bad enough to consider those options instead. We all understand the business model here, try to get as many paying subscribers to use existing network investment.

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.

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.

I ordered this SIM card for a trip to Germany, Italy, Spain and back to Germany. The card included more than enough talk and text time and I figured enough data for the duration of the trip. I activated the card in the US and hoped it would work as I arrived in Germany although I was not sure what to expect. When I arrived in Germany, the phone I bought for the trip literally died upon arrival. I bought a new phone in Germany andinstalled the SIM card and voila, it picked up a signal, started up the data and I was good to go. As I travelled to Italy, Spain and back to Germany, the Sim card connected with a local wireless provider upon arrival. Connection was always good and it turned out the data was more than sufficient for the 2 week trip (I used it to check email, read the news, searched for travel and other info, as well as used Google map for driving and walking directions, but kept video watching to a bare minimum). This was a great value and I will consider purchasing a prepaid SIM card from this provider again.

I bought it for recent trip to Switzerland and Singapore. Set it up a couple days before with a designated activation date. Was able to test with data in US. Was able to use LTE in SF Bay Area (but no calls or texting allowed as indicated.) When I arrived in Switzerland, my phone automatically switched to Salt which has really bad connection. Eventually, I figured out in the iPhone Cellular->Network selection, there are more than one networks available. And when I switched to Sunrise, it was excellent. Was able to use it in Singapore too. Multiple networks are available in Singapore as well and of course there is no difference since it's a small country. Too bad it does not work in Malaysia. It will be excellent if it covers Malaysia as well. 5G is more than enough since Wifi is usually available in most places.

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.

Die SIM Karte kann online aktiviert werden, in welchem Land man sich dabei befindet spielt keine Rolle. Bei der Aktivierung kann bzw. muss man angeben, ab welchem Tag die SIM Karte aktiv sein soll. Ab dem angegebenen Tag laufen dann die 30 Tage. Bei mir hat die SIM Karte ohne Probleme in Deutschland, Panama und Costa Rica funktioniert.

La utilicé en Reino Unido, Holanda, Bélgica, Francia, Italia, Austria sin ningún problema de cobertura o funcionamiento. Automáticamente al cambiar de pais llega un SMS notificando la cobertura y listo.

Urgh, same thing happened with my other phone. Lost my account, not able to sign in to check, weird! Spent weekend testing to see if it was my phone that was the problem. Eventually completely lost all signal on Sunday - no account and no signal! Staff member at a sim provider store suggested I try to get a PAYG sim from Tesco, said she was not surprised about my problems with Three sim but wasn't going to elaborate. A Tesco staff member at the Glasow Queen St branch , possibly a manager - took the time to help find me the right sim. Got the £20 GiffGaff sim with 80GB data - although the credit seems to go quite fast if you make quite a number of calls - so while not a complete solution, it is still better than NO SIGNAL - here's looking at you Three - dishonest business practice.

Excelente precio calidad. Muchos gb 12 de datos y llamadas ilimitadas. Sobra para un mes. Toda union europea

This was a great way to save money and not give Rogers Canada any extra money for using my phone in Europe. When my plane landed in Paris I put in this new SIM card. My phone restarted and it automatically configured the sim to work. Had data before I left the airplane. When I took the train to London the card continued to work as expected. A perfect sim for traveling around Europe
