Three Mobile Unlimited Pay As You Go SIM - Save £15 with our Go Unlimited Sale.

Unlimited for 20.EDIT:Been using two months nearly in my 4G Router and it has been 100% rock solid with an average of 25MB-30MB/s. Never had a dropout and my connection is lighting fast - as good as home broadband.First Three service is useless but you shouldn't need it. Yes it will say credit balance of zero, that is because your plan is activated and the initial balance taken off once you put the SIM in the phone, it starts then and counts down from that time. Calls and data should work OK but bear in mind I needed to try in two devices as the first Android phone wouldn't even connect to three.I tried in a second Android phone and it worked great (this was on the advice of Three Customer service but it took three chats to find this out - they are clueless).So if it doesn't even connect on one device try another. I have no idea why the first phone didn't work as it was a 4G phone (Android Moto X Play)., the second device (Kindle with SIM slot) worked great for access, and latterly my 4G Alexa Router (Huawei AI Cube 4G) works fine with the card.Speed:Usually 20-25 MB/s, sometimes 35MB/s, peak I saw 50MB/s which was fast.Far better than my old GiffGaff (useless) and O2 (not much better) data and almost indistinguishable from EE speeds (which are fast).

I purchased this SIM as it was supposedly an Amazon Exclusive of Unlimited Data, Texts & Minutes PAYG deal. The SIM had a trial period on it (it only lasted a couple of hours in my phone) but once this finished I was told that I had to purchase a Top Up. As I had already paid £18 I was unamused at this so contacted Three to find out what was going on. During a chat with Three rep I was told". . . currently I do not see the Prelaoded data pack on the account and hence the only option is to do a Topup on the account and we can help to get a data pack" Unhappy with this I informed them that I would be taking the matter to the ASA for misleading advertising. I was informed that "It seems that the SIM is faulty with no allowances" and they made me an offer that was not the pack that I paid for. It took me a wee while but on once again invoking the ASA, a few more minutes of chat & sending of Proof of Purchase to Three I now have the bundle I paid for.

with the reviews being both good and bad i really was unsure,after talking to amazon on the phone i was reassured that if id been miss sold i could get a refund so i went ahead and ordered....mine arrived and straight away iv loaded it on to my phone uploaded older three mobile app so I can auto renew data pack £20 a month for12 months and up and running, put in home WiFi box and we have Internet access throughout, can't say weather be good for gaming but we'll be running devices and laptops unlimited, and guessing ps4 will be okay also

I had to contact Theee because I could not send texts but tha issue was resolved immediately and all is good now worth every penny

I’ve been purchasing this pre paid sims for months and I’ve never had any issues!I just pop it into my phone received a welcome text! Then transfer the sim to my Wi-Fi router and I have unlimited data ( internet)for 30 days!I have 4 bar signal in my areaValue for money especially when the promotion is on £20.00 instead of £35.00 unlimited data! I believe that’s a prime exclusive offerWould definitely recommend

The auto renew option to secure the 6 monyh 20 pound deal was not working. After contacting three they advised the service was down and they could not assist

Good.

Very good value for money and good very connection no problems at all
