3 Mobile Three 4GB data Pay As You Go SIM

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.

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.

I bought this for my husband. He installed it and it worked briefly and then stopped (weird, given what happened later...). We contacted Three who refused all knowledge and said Amazon had not passed on the money to them. You essentially get a free, empty PAYG SIM card with no pre-paid top-up and the money you've paid Amazon seemingly hasn't been credited to the SIM card. Not sure if it's Three or Amazon or the two in cahoots, but someone is running a scam here or has set up a faulty chain of revenue transfer. Buy directly from the company so they can't deny knowledge of the top-up money. Luckily, Amazon have agreed to a refund.

We have terrible broadband reception and needed to run a WiFi camera for lambing from a shed. It worked a treat although reception was occasionally a bit on and off but that’s rural areas not the fault of the sim

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.

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.

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.

Arrived same day, easy to set up (I recommend setting up in country of purchase before travelling). Had 12GB data for a 2-week trip to USA and didn’t have a problem with the signal (only in thunder storms of course!) but it was worth the money for the convenience!
