Three Mobile 30GB Data Pay As You Go SIM

Ordered a 10Gb and 30Gb card for a trip to UK and Germany. Shipped to US, arrived on time. Activated both cards in the US prior to the trip. Within 30 seconds of turning on phone, got a text that included the phone number. Logged into Three app and could verify that each card had the proper amount of data. Was great to have our numbers before traveling so that we could give to airlines / hotels / family members, etc ahead of time. I was worried that if the card wasn't activated in UK that something wouldn't work right, but it was great. If you activate before the trip, be aware that it expires 30 days later, so don't activate too early. I did confirm that both cards could connect to 4G since I read some negative reviews about that. I guess we got lucky. Highly recommend!

Poor network coverage in UK and Abroad I bought this after reading on a money saving website that it was the best for roaming. As soon as I received and activate it I noted the network coverage whiles here in the UK was very poor. However, I was hopeful that when abroad (I went to the USA) as the connection would be with the 3rd party network it would improve. To my disappointment this wasn't the case. When I manage to logon to the network (either T-Mobile or Verizon) it was still a "hit and miss", mostly "miss". My main purpose for needing the roaming was to have internet whiles I'm out and about for navigation, chatting etc. but I couldn't rely on this roaming so I was force to find an offline navigation App and download the maps I needed. But it also means I couldn't communicate as I had very limited or no connection most of the time. I bought a 30GB data pack and only get to use about 600MB not because of low usage but the network. I will not be recharging this SIM at all. If your sole purpose for buying this is same as mine, then don't. Waste of money.

I have only good opinions about this SIM. I bought this SIM travelling to Europe and I activated the SIM being in Netherlands with no problems at all (just insert SIM and you receive your new number and data pack in a few minutes). I used it all around Europe including UK, with the best cost - benefit ratio and a great service. The internet service is good, reaching connection in 4G and 5G most of the time, depending on the country. There are some inconveniences to call and receive calls, I suppose it's due to being connected to roaming networks, but overall service is good. One last thing, when travelling abroad, remember to activate roaming on your phone.

Bought 3 for a trip to New York. Worked for Internet etc but struggled to make calls.

I liked the fact that has a rolling month to month with data and calls included it's fast light and easy to connect great for medium to heavy use

This did not work in my phone it asked for code but none supply so it did not work. going to try an other ipad to see if that works.

The SIM is super easy to set up if you do it from the UK. Just unwrap the card, insert it into your phone and you are good to go. No activation process, no waiting time, and no extra configuration required (at least with my iPhone 13). For the price you can definitely get better deals (more gigabytes) with other providers, but if you need something super easy and very quick to setup this is it.

DO NOT BUY - especially if you want short term fixed amount for overseas visiting relatives The SIM card arrived on time and did not activate. I reached out to the supplier and the card did not work when tested in another handset either. During activation attempt a text was received saying account ready with 100Gb and £0 balance (I purchased £30Gb for £14.99) It was too difficult to try and get working (0 bytes of information used) and more helpline support offered when tried to return for refund. This was an utter frustrating waste of my time and money. I will definitely not buy again
