Three Unlimited 5G Data SIM Card - No Contract or Credit Check - £25/Month Rolling 30-Day Subscription

Bought for my mobile Mifi device as in a property that can’t have cable. Easy set up, works great on my Apple TV etc. no problems so far.

I was getting tired of my broadband supplier locking me into a contract with built-in price rises, so I took a chance on buying a 5G router and this unlimited data sim. It was one of the best purchases I've ever made. I'm now getting upwards of 300 meg speed in the day, and 500 meg (sometimes) late at night, when the phone network is obviously less well used. That matches and exceeds my previous 250 meg broadband speed, which is a fibre line to the house. Fantastic. And if I go on holiday anywhere (UK only), or move house, I can take my super-fast broadband with me. As I've never been on the Three network before, I did check online to see if I was in a good area for Three, and it was fine. If you're still unsure, try a one-month sim to make sure it's a good network for you. But always come back to this company for your long-term deal - they do sims for all the other networks too. The cost per month is incredibly low, and I'm the kind of person who likes to pay once, up front, so now I don't have to pay again until July 2027. No internet bills for 19 months! Customer support was excellent. I needed the 'mature content block' removed, and that happened in less than 24 hours. There are more blocked sites than you think, not just the obvious ones, so you may need that. It's very easily removed, you just ask. Unlimited actually means 1000 GB of data, after which your connection is slowed until the month rolls over again. For me that's not a problem. The router is telling me how much I've used and I probably won't even break 500 GB this month. And that's with me watching a huge amount of internet TV, and doing a lot of downloads and uploads. Not a lot of 4K TV in that though, so if you have a big household and everyone wants to watch lots of 4K movies all day every day you might reach the 'limit'. Even then, the company contacted me and offered a 'truly unlimited' deal, but I didn't need it to pay the extra for that. One small niggle was that my IP address kept changing, sometimes every minute, and that made my banking site constantly log me out, and there were problems staying logged into my web-based email too. Looking online I found that you can change the default APN to '3internet' and that will give you an IP address which stays fixed for longer. My problems disappeared as soon as I did that. You'll need to check online how to do that with your router - mine is a Cudy 5G router, also bought from Amazon. From what I've seen this seems to be specific to the Three network. APN = 3internet, leave the username and password blank, and set 'Authentication type' to PAP. I bought this sim to test it until my fibre contract runs out, and it's so good that I've switched off my old box altogether, and use this sim card for 100% of my internet now, with 3 computers, a TV, tablet, and mobile phone wifi all connected to the same router, powered by this Three sim. Highly recommended.

Very good deal, though Three coverage is poor in my area and it can't find any Vodafone signal at all.

Absolutely useless. Constantly freezes, riddled with error codes, but yet hot spot from phone works without issue on another provider. A waste of money. Lesson learned.

My second purchase of these - I really wish I had discovered them years ago, instead of paying a small fortune for "normal" broadband. After having to move into rented accomodation after selling my house, I needed immediate wifi and using a mobile hotspot was just too expensive for the amount of data I use. So I bought a Cudy router for about £30 (B08W2XZ6KM) - nothing spectacular, but it does the job. With that, you literally just slot this nano sim in the bottom and you've got wifi in less than a minute. So easy to set up ! As I write this, I have the following devices connected : One laptop Two Desktops Amazon Echo Two mobile phones Two tablets A projector Two Printers And a partridge in a pear... Quality ? Well, it came well packaged and no damage, so all good there. It took less than a minute to activate. No connection problems in my neck of the woods, and all in all less than a tenner a month. Not really much else I can say - other than my last SIM ran out last night. I didn't realise until about 12.30am this morning, so I quickly logged on with my mobile, bought another... and it arrived less than 12 hour later. Can't fault that at all. Speed wise - well, I'm not a gamer so I cannot comment on that kinda thing. It is fast enough for me and the devices I use. I can seemlessly go from Netflix on the computer to the projector without any lag and upload Amazon and eBay listings without a hitch. Data coverage ? I am in East Lancs and have no problems there. Naturally, I can't say what the rest of the country will be like, but I'll test it when I take the camper on the road in a couple of months :)

quickly dispatched, well wrapped, easy to set up.

Arrived quickly - very easy to install. Works perfectly in my internet router providing high speed internet access. A great value for money product

Arrived promptly. Simple as popping the SIM into 5g router and away you go. Speeds are same if not more stable than smarty which was the network used previously.
