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

I have used mobile broadband for years, and while it is generally a little less reliable than landline broadband, it is generally faster overall, at least for downloads. I wouldn’t recommend for gamers who play online, even with the lower latency of 5G, as it still won’t be as good as landline, but for everything else, it is great. You can buy 4G routers cheaply for this SIM card, and even 5G routers are becoming affordable now. Just don’t cheap out on a slow CAT 4 router, as your speeds will be slow. CAT6 or 7 and above will give you carrier aggregation, which means your download speeds will be significantly faster. I noticed that some people said their internet was slow. Make sure you have a 4G router that is at LEAST CAT 6. You can get them for between £50 and £70 on eBay. Preferably go for CAT 11/12 upwards, which generally costs the £100 mark, although sometimes they can be had for £50 if you are willing to buy second hand. They are far faster than routers less than CAT 6. Avoid any router that is CAT 4 at all costs, as they will be slow in this day and age, and not fast enough for 4K ultra HD streaming. About the fastest 4G router you can get is the Huawei B818 which is CAT 19, but given the price these go for (£150 to £180), you are entering the price zone where you could get a 5G router for the same money, which is worth doing if you know the coverage of 5G is available where you are. I am using a ZTE MF286D, which is a CAT 12 4G router that can be bought cheaply off eBay (around £60), but mine is from my previous Three data contract. I am averaging 125mbps and about 20mbps upload speeds with it in the evening time. Also, check the coverage of what you can expect with Three network before you buy. A cheap option would be to buy a Smarty SIM card and buy one of the cheaper data packages for one month, as it uses Three network, and you can figure out if this Scancom deal is fast enough for you with a good signal. Also check out CellMapper website to see where the cell base stations are in relation to your home. Remember that if you want to turn off the content block which filters out 18+ websites, you need to contact Scancom via [email protected] with the number of your SIM card and/or the code off the Scancom envelope it was in when you received it, and ask them to turn it off. It will take about 24 hours for them to do it. They run the business account for the bulk Three business SIM cards, so you can’t just contact Three to remove the adult content lock. Scancom need to be the ones who remove it. They removed mine 24 hours after I emailed their support email address. Also, remember these business plans have a fair use policy of 1,000GB a month. If you exceed that speed in a given month, the connection will be slowed down by traffic management until the next month when it refreshes with a new 1,000GB allowance. I paid £199.99 for my deal, which works out at £8.30 per month for the 24 months I’ve paid for, which is insanely cheap. You wouldn’t get any landline broadband plan for anywhere near as cheap as that, especially once you add line rental. The only negative thing, which is nobody’s fault, is the price went down to £149.99 a few days after I bought it, which works out at just £6.25 which is an insanely good deal. My Dad was happy though, as he just bought one at that price to replace his Three 24 month contract for mobile broadband which ends in a few weeks. The only downside of mobile broadband packages like this one I can see, is for those who are very heavy users. While it is described as unlimited in the listing, and it technically is, the speed will be slowed/capped via traffic management until it refreshes the following month with a fresh 1,000GB of data. For 90% of people, 1,000GB per month is plenty, and equal to about 300 hours of nonstop streaming YouTube/Netflix in 1080p full HD, or 100 hours of 4K ultra HD streaming. Remember there are 168 hours in a week so work your usage out from that. If you streamed YouTube/Netflix for 6 hours a day in 1080p full HD, you’d use 540GB per month. If you streamed the same length of time each day but at 4K ultra HD, you’d use 1,800GB per month so you’d go over that 1,000GB cap, but who watches 6 hours streaming EVERY day, especially at 4K resolutions? Not many. Just remember that mobile broadband is a little less reliable overall compared to landline broadband, and more prone to bad weather, but don’t let that put you off. It is far more reliable nowadays than when I first started using mobile broadband 18 years ago. It is very rare that the connection doesn’t work. You can also take this connection with you if you holiday anywhere in the UK, such as a caravan and so on.

Product arrived on time with secure delivery. Bought a tp link mr 600 and Poynting XPOL 01 5g antenna (backwards compatible to 4g) to boost signal. Used router with smarty data SIM (which is on 3 network) for 5 months and it worked flawlessly. I used 200-300gb a month on this deal and it was £18 a month. So, with delivery and the SIM being £205 for 25 months it's a no brainer as the cost will work out at £8.20 a month. This will save £245 over the 25 months compared to smarty, in the current cost of living crisis savings like this cannot be missed. The performance seems exact same as smarty - 20-40 down and same upload. As both networks are on 3 I expected performance to be the same. Had to email Scancom to have adult block lifted - this wasn't a problem. The only niggle is there is no online way to monitor usage, so I have gone into the router settings and set the counter to zero and max at 1000GB. The counter resets on the 8th of each month (which is the refresh date). This is a bargain, considering similar speed basic fiber is now around £27 per month and this works out at £8.20 - £18.80 saving every month. ==September Update== All is good, everything working fine, streaming lots of TV programs, internet radio on Alexa, browsing etc, this SIM has performed flawlessly. I have been putting £9 per month into a sinking funds account so that the funds are there to purchase another prepaid plan from scancom when this one runs out. This is a great way to cut cost by a large margin. Usage has been between 200-300GB a month so well within the fair usage limits. ===February 2025 update=== Everything working fine - streaming on firesticks, radio on echo dot, browsing on phone & tablet, video doorbell, internet hive boiler are all working perfect. Great value for money - many wired internet connections are near £30 now - big savings are being made month after month!!! ===July 2025 update=== Works flawlessly, I've had absolutely no problems, my mate and my dad have ditched landline based internet and set up their own 4g networks now with scancom sims, they've gone for 500gb & 350gb deals respectively meaning they are paying £3.50 and £2.97 per month. My dad in his late 80s was asking "what's the catch?" Lol. There's no catch, just money saving month after month.

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.

Quick delivery. Plug and play. It just works. Good pricing

Been using one of these since Feb '23 with rare exception. Unlimited isn't entirely true, it's an 800GB monthly allowance though I never did figure out the "reset" dates, messages are sent to indicate your approaching this cap though if you have this slotted into a router like myself those are easily missed. For browsing and web apps this cap might as well not exist but if you are downloading multiple modern video game releases/updates you may have to take this into consideration and have a back-up plan, i have a seperate pay as you go Sim on standby just in case, even with that extra cost your still getting better value for money than a non-fibre broadband line. Content Filter was enabled by default and I did have to contact support to have that removed. This was through the seller as I didn't have the necessary details to go to three directly. Service has been fine, only one outtage that wasn't fixed by a router reset or waiting 10 minutes and even that exception occurred late at night, everything was fine by morning. Very happy with my purchase and will likely do it again come expiration of this current sim. Update Novemeber '25: Final month on this SIM, has held up just fine, will be purchasing a new one

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.

The ease with the purchase experience and installation into the phone was great. From there it goes down hill a bit as the 3 signal is quite patchy in my area despite 3s signal map stating I'd get good 5g service outside. No 5g when in use and 4g+ fluctuates constantly. I even placed the Sim in my home router and purchased an external omni directional aerial, but the fluctuations remained and speeds were not improved. Disappointing but you don't know about these things unless you actually try it rather than relying on signal maps from the various providers.
