Great value
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.

Three Unlimited Data SIM - Uncapped 5G - Great Buy provided you have a strong signal!
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.

Regret purchase
Internet access is VERY UNRELAIBLE. I cannot get internet in daytime hours ,,, been like this for 3 weeks. Not great when you work fr home . They offered to send a new SIM that hopefully works, BIT VERY slow to respond resulting in me having to purchase extra daily internet . It’s NOT FOY FOR PURPOSE . It is obviously corrupt that Three have received ‘Best This, , Best That Award ‘ … As in photo . WHO is awarding & are they asking actual customers like me ????

Jitter and latency issues but does the job.
I bought the yearly uncapped SIM at a good price. It took a few days for the adult content filter to be removed by contacting Scancom. However, I noticed on Youtube that my videos were stalling and stuttering usually at around 11pm to midnight. I done ADSL speed tests a few times and often get very high readings for Jitter and latency. This doesn't affect the videos I watch very often, but if you are gaming you might have trouble with these SIMs. Generally upload and download speeds are good so I am happy enough with my purchase.

Does the job well.
It does the job I expected and supports my need for our own wifi in temporary office space.

3 Unlimited SIM - good value for money
Thank you. I received the 3 Unlimited SIM card last week and have been using it with a Netgear Nighthawk 5G Mobile Router, along with a Poynting antenna to enhance signal quality. The 3 SIM card has been performing quite well. In my area, it appears to be better than another Unlimited SIM card I had used for the past two years. I have noticed that the signals are more stable and of higher quality, and, most importantly, there have been no interruptions (unlike with the previous SIM card). The testing results are quite good, except for the upload speed, which is a bit low. I believe the upload speed could be improved by positioning the antenna outdoors instead of indoors. Based on the testing results so far, I am pleased with the 3 Unlimited SIM.
