Three by Three Mobile Data Pay As You Go SIM, Unlimited

Perfect

( I am using in a unlocked Wi-Fi device)Great sim as there is no sim number on packet u have to try to find what the number is so u can activate it but other than that it has great signal once first set up is done

Bought these 2 cards for my brother who was travelling to UK for 1 month.After inserting cards couldn't get anything working, after about an hour of trying to get in contact with customer support we finally got activation for about an hour on one of the sim cards. Other didn't work.Signal/connection seemed really bad and often only got 3G service.Next day both cards not working.More problems getting any help from customer support.One more day with connection 3G then 4G and then no service.We do not want this kind of service when on holiday, don't want to waste our time.No refund offered.DO NOT BUY THESE SIM CARDS.

Value for money with good connectivity. Easy to set up and use.

Came to the UK to visit for a few months in the south west so needed a pay as you go sim. Worked well as it can, good price, and allowed me to travel with less worry. Just check your coverage before purchasing.

It's quite a good deal with unlimited downloads etc, but the Three website stated my signal strength was excellent.... It's not. When I moved the router or phone to another postcode area, it was good. Maybe check with a friend etc first who has three mobile etc.

Purchased to use in a sim WiFi router unit, works fine. Only problem is you do not get a phone number on the pack. So you have to put into a mobile 1st to open and register the sim, you then get a phone number associated to the sim. You need this to be able to register the sim so that you can then check usage and purchase top ups.

I’m from the United States and staying in Britain for 2 months. This SIM card was the perfect way to be able to use my phone while traveling. I have a new phone number and I can use my phone here without needing to be on Wifi. But everything else on my phone is the same.
