Three 25GB Data SIM – Uncapped 5G Speeds – Renewed EVERY MONTH Until 8th FEBRUARY 2027 – No Contract – Ideal for Business Mobile Broadband, Routers & Phones

After Vodafone informed me (and other previous customers) that they were stopping their Smart SIM service, which I originally signed up to provide 4G LTE connection to my BlackVue DR900X-2CH dashcam (using the CM100LTE unit), I contacted BlackVue for advice on an alternative and also carried out some research of my own.BlackVue’s eventual replacement data SIM for the UK did not seem like a good deal to me, but luckily I stumbled across this SIM. I had never heard of this service/type of SIM before, and there were mixed reviews about its reliability. However, at the price I got it, I thought I could give it a go.The set-up got me baffled, because the BlackVue app just wouldn’t move on to the next step after I had inserted the SIM card. It turned out that the app doesn’t like VPNs. So, after turning off the VPN on my phone, which I was using to set-up, it worked fine.The connection speed seems fine - I’m able to do a live stream from my dashcam, just as I did with the previous Vodafone SIM. Bear in mind, the CM100LTE module is capable to 4G only, so I can’t comment on the 5G performance of the SIM. This SIM is great value for money. I’ve not run out of data and I will surely get a new one when the current service expires.

These SIMs regularly come up on sale on Amazon, and I've managed to pick up a couple for under £50, both for over 2 years worth of data.Amazing value for tablets or for remote monitoring devices which is what I use them for.Data speeds are fast enough for my needs, and I can remotely login to Raspberry PIs over the connection without a problem - you do need to use a third party service like PI Connect or Dataplicity to achieve this kind of remote access as these SIMs don't provide static IP addresses for the device they are installed in (SIMS with static IPs are really expensive!)

If my business was this 'business grade' I'd be out of business... despite having a good signal, I can't actually use the data. It's excruciatingly slow to non-existent. There's a reason 3's business SIMs are cheap and that's because you won't be getting anything like you think you will. Wish I'd taken more notice of the reviews. My advice would be to avoid. I wish I had.

I purchased the 50Gb/month SIM. Been using it for 4 months now as a second sim in my mobile phone and I'm very happy with performance so far. As always, speed can vary, but in good 5G areas I get over 900Mbps download speeds. Upload speeds are always a lot less but perfectly good enough for Facetime, Teams, etc.

Easy to set up, just popped into my phone, works right away, job done.I do have a couple of issues though, firstly when does the data renew each month? I'm guessing maybe the 8th? Secondly there is no way of monitoring your data usage, you just have to hope for the best, that's a problem when your on such a small data bundle, it's very easy to run out. On the positive it is cheap and it works so I'm not gonna complain too much. I would buy again.

A Scancom Three SIM is all you need to connect your router to Three mobile for superb quality and value for money broadband. Nothing else comes close! It's very sinple to use as well, no logging in, no activation needed, just pop it in your router and it's working! If you are worried about using too much data then get a Huawei router which you can set up in the Tools section to show your usage, Forget all the other costly broadband providers using phone lines, cables and fibres, just buy a Scancom Three SIM and a Three 4g/5g router. I have been using a 500GB SIM for a year with speeds up to 500 Mbps and absolutely faultless costing me about £7 a month over 2 years. This is the best thing for the internet since Tim Berners-Lee!

This is such an easy solution if you need a small amount of data. For me, it's gone in a Zello POC "radio". It uses very little data, so I couldn't justify paying for a contract or expensive monthly SIM.This works out at around 65p per month at the time of purchase, as it was on offer at £19.99 for 30 months.Excellent value, easy to use.Connectivity is good. I have a full 4g signal at home.The only issue, as others have said, is you can't monitor your data use. It's not an issue for my purposes as these use very little overall. If putting in a dongle / hotspot, you may want to setup monitoring on your device. It's not clear if it just won't work until it renews if you do happen to use all data up.

This is the second 3 mobile data sim card I have bought and use it to connect Dr900s dash cam to the cloud.Speed and connection are good.This will depend on your area and wifi router you use.Works OK and getting a good picture on my mobile phone.Bought a 25gb data sim card as there was a great deal on at the time.Lots of negative reviews again but works for me.
