Three Mobile 1 GB Data Pay As You Go SIM

...a 'Pay As You Go' sim card with the ability to load as little as £5 on it and just use it once in a while to keep the card 'alive'. I needed a second phone to receive both sms and calls from all those firms that want to continually plague you with follow-ups after getting insurance quotes/utility quotes etc etc. I had a spare phone and this is a great solution without clogging up my day-to-day mobile. Easy solution and ideal for my purpose - recommended by me

The SIM card worked out side ok but not in the house. The card snapped very easy when putting it in to the phone. I was using this for my spare phone . However my main iPhone works great in and out of the house so in view of my experience I have returned my phone and will see how the SIM card works when I get my new phone.

works fine after a nightmare2 hours trying to put credit on it website would not accept my password eventually spoke to someone who gave me instructions on how to do it without registering perhaps this should be made clearer on the website

Hey, it surprised me somehow. The SIM card needs to be actives through phone by turn off and turn on for the first time use. Then the SIM card can be plug in either phone or mifi devices(not a usb type). Comparing with other pay as you go data sim, it definitely is cheaper and more flexible.

This card appears to be out of date . Set up was easy but you get a message telling you the costs are now 10p per min and 10p a text and 5p data. Other than that pleased.

Bought for use on holiday in the USA as it wasn't included in my current mobile providers package. Worked with no problems at all in the USA, and a fraction of the price of using my current mobile provider. Bought another one for my wifes phone, again no problems

Seemed ideal for my situation. Delivered promptly. No Idea about quality of the network. Bought credit which was added, but then could not register and could not use for calls or texts. Speaking to Three it turned out to be data only sim. Three say they will refund credit. Three also said they are withdrawing this 321 sim.

This made our trip to Europe so much easier. It was a life saver in multiple situations. We were in five different countries and it worked great in each country. I just popped it into my iPhone 6 before landing and upon arriving in the UK, turned on my phone and it worked great. The only minor hiccup we had was when we went to Spain it didn't seem to want to work. Once I got to my hotel with wi-fi I chatted with 3 tech support on their website and they had me change the setting to turn on roaming and set Carrier from Automatic to manual and then they told me which carrier to select for Spain. It worked great in France, Italy and Switzerland as well. One thing to know is that if you are texting or calling a European number, you need to dial a + (on iPhone press and hold on the 0 to get a + sign) and then the country code and then the number. As for your phone number, it leads with a 0 for some reason, you need to omit that 0, so your number when you have the SIM will be +44 then the number on the back without the leading 0. It took us a bit to figure that out, but once we did everything was seamless. Make sure you buy enough minutes/data because you can't top off without a UK credit card. We had plenty of data for our 2 week trip.

This SIM worked as advertised in London, after some initial trouble setting it up. Luckily, online chat support is available 24/7, although the wait was over 30min, and it did get sorted out after a couple of hours of trying. Unfortunately, once purchased, this SIM card can only be topped using a UK credit card. I tried to get more data, but that doesn't appear possible for non-UK credit cards.

Not a card to buy as it does not work as described on the web site "Amazon.com" I was travelling to Spain and other europe countries and I could not use he card for making phone calls to USA and even in europe it was not easy to activate the card. I had to call UK customer service for any custoemr issues. Very poor activations instructions. Do not buy the online card, it is better to buy local country sim card just for peace of mind.

I just came back from a Belfast and Dublin vacation. On recommendation on a travel site, I decided to try getting a sim card before I travel. Usually I get a sim card when I arrive at my destination. Got this card. Pop it into an unlocked phone while here in the US. No problem setting up the phone. Got a +44 tel. number which is a UK number. Connected to T mobile here in the US. Got a welcome text stating that US is part of the Go Roam countries. Access the internet (looking up yahoo.com) and again it worked. Did not try to call someone though as US phone numbers incur a surcharge or top off but I was able to call the number for 3UK On arrival at Dublin Airport, got a welcome text again and the phone connected to 3 IRL. Went straight to Belfast which is in the UK. Did not work there.NO text, data or phone service. Chat was about as useful as a slingshot in stopping a charging rhino. Managed to go to a 3 store at Victoria Square and explained what I had already done (am a techie of sorts). He said that be believed this is a 3 Ireland sim card which definitely will not work in the UK. 3 UK and 3 Ireland are two separate entities! He tried one fix although he did not have hope for it. What he cannot explain is why I have a +44 tel. number. I asked him if he can sell me a sim that will work in Dublin and he said yes but he won't because he has very strong feelings that as soon as I get back to Dublin, the sim will work again. Besides, he said it is better to get a local sim since I would be in Dublin for a number of days. Guess What? When I got back to Dublin, I got that welcome text again telling me that Ireland is part of the Go Roam countries. Strange that the sim would not work in the Belfast which is in the UK. A UK sim not working in the UK. Re. the function of the card in Dublin. I would say just passable. Right in the city I had times of no data. Thank God there was a lot of free wifi. I would say, not recommended.

Purchased this before for a Paris trip. Worked in one phone and not the other (my wife and I). I didn't do a review but I wasn't completely satisfied but it's a UK company. Bought more for trip to London and we both have the same phone now (a Huawei model). Popped out the stateside sim on the plane upon landing and popped these in. Got some texts from Three that they were configuring the phones and we used the 4g data for 9 days or so to use for google maps and tube and bus apps to show us where and when to catch transit. The phone numbers assigned didn't seem to work for calls but I didn't pursue it very far because I really just wanted access to gmail, web broswers and maps and it worked for that. You basically can't get very lost if you have google maps and apps related to transit. I thought it was worth the purchase.
