Worked in the USA
I bought this item to use the internet in Las Vegas when I was there for a couple of weeks in September. It worked perfectly and whilst there was only 12gb available for use in America out of the 30gb I only used a couple of gb during the whole period. I didn't need make any of the free phone calls. I could have got away with a 10gb or 20gb simcard but I am a cautious person. It was easy to set up on my phone. It probably been even easier if I had a dual sim phone.

Update to Update .... Yeah Initial comments were right - BUYER BEWARE!!!
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.

Not What Was Advertised
I purchased this for a friend visiting UK , I purchased 10 G as advertised however the "3" pack had a sticker on the outside from TSIM saying 4 G of data, after 1 day of use we were told our allocation had been used up and we needed to top up with another credit. I do not know how much was in the sim but certainly not the 4 G let alone the 10 G advertised. The phone no longer worked . lucky I was with my friend and called to complain advising if we did not get satisfaction we would take up with Amazon and after speaking to an Indian call center we got the 10 G for 30 days as originally advertised credited to the card. There is nothing wrong with 3 but I would not buy a card through Tsim.mobi.services again. Perhaps an admin error but then again make your own judgment .

Great price
Seems fine so far and I like the fact it lasts 12 months.

Perfect for a US Trip!
We bought this before our Florida holiday, 3 network allows free roaming in the US and this SIM card comes pre-loaded with 8 GB which was more than enough for our 10 days stay. Delivered the next day by Amazon and was very easy to set up, literally only took a couple of minutes. This was a perfect solution for us and saved us a small fortune on roaming charges. The one drawback is that 3 do not allow tethering (mobile hotspot) so you can only use this sim in one device.

Does not include calls to non-UK numbers
Although offered as unlimited calls, texts and data, that ONLY applies in the UK. If you want to use this product overseas then firstly you MUST make at least one call in the UK before you leave for overseas locations. If you don’t then the SIM will not activate correctly. Additionally, you will be limited to 12GB of data so not unlimited in any way. Thirdly and very importantly you cannot make calls to non-UK phones, or send SMS texts to them. You will have to buy a top-up to use this function. This is not well explained in the packaging, but does appear on Three’s website IF you know where to look. Calls in both Abu Dhabi and Australia (both are Go Roam destinations) to non-UK numbers are £3/minute so beware. I only discovered these limitations once overseas and after becoming very ill. Threes support desk were hopeless and told me that it should all work so even they clearly don’t understand their own products which doesn’t inspire much confidence.

3 Unlimited Data 3 Month Sim
Excellent product and performed as advertised. Good coverage even though we are presently anchored off the Southern English coastline. Used extensively for studying and Netflix, lots of Watsapp and could also enjoy Minecraft(ing) with my son. Thank You

Best option for mobile net for international travel
It’s a great solution if you need mobile data and internet while traveling abroad. Worked great in US and across Europe. Got a suggestion to purchase one on the airport while going to US. And I buy now for my international travel. Best deal to stay connected online.

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.

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.

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
