Three Unlimited Data SIM - Uncapped 5G - Preloaded MONTHLY Until August 2026 - Plug & Play for Routers & Phones - Access to Three & Vodafone - Connects to the Strongest Signal available

Purchased the Three Unlimited Data SIM - Uncapped 5G with 11 months remaining - works straight away - simply put the SIM card into your 5G router and within 2 minutes it registers itself and works.I checked the signal strength on the 3 Mobile website before making the purchase, and it's incredibly good and fast.Highly recommend checking the signal before purchasing.

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 support@scancom.co.uk 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.

I bought this Scancom SIM for a mobile router to replace landline Broadband at home.Scancom provide images on the Amazon website that provide product information.One of those images has the Scancom name printed on a red background top left corner, with a list of product descriptions.At the top are 4 Network logos with names EE O2 Vodafone '3'.Included in the product description is stated :-"strongest Signal - 4 Networks preloaded on one SIM"What I received was a clearly marked '3' Network SIM with no other Networks loaded. I had hoped to use the O2 Network because I already have an O2 SIM and get a strong 5G signal.I also checked 3s Network coverage using my postcode, which reported as "Excellent". However, signal strength was 2-4mbps indoors and outdoors. I tried the SIM in 2 devices with same result.Excellent customer service from Amazon, who issued a full refund.

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.

As expected. Smooth transition and set up. Easy to use and it works well.

Good product best deal but Mr's wanted broadband instead

This is a great option for broadband, woks brilliantly and saves the extra pressure of monthly bills, works for my business as we are a new start up.
