Three Unlimited Data SIM Card UK – Preloaded Data SIM for Home Broadband Replacement, Routers & Mobile WiFi – No Contract, 30-Day Plan

Worked perfectly - used to provide internet to my laptop from a SIM enabled tablet - OK not the fastest connection as signal in the area was noted as flaky. Activated in well under the stated 48 hours - by email

Honestly, the description made me laugh — “No Contracts, No Credit Checks, No ID” — sounds so simple, right? But surprise! After you get the SIM, you have to send them an email just to activate it. No portal, no self-activation — just old-school email. And here’s the best part — they say the network will process it at midday and the service will go live within 48 business hours. In reality? From the time I sent the email to the moment it was actually activated, it was well over 48 hours. For something advertised as quick and easy, it feels more like waiting for a parcel from overseas. Not impressed.

Brought this data only sim for when I was put into temporary housing and I wasn't sure how long I'd be in there but I knew it wouldn't be long enough to have broadband wired in. I brought a device off Amazon to fit the sim in and activated the sim as per instructions. It was very simple to do and the sim activated in great time. I have 3 children who all use devices that need internet including our tv and I've not had a single issue connecting or staying connected even though 3 is not named in my post code as great signal. I also needed to extend after the initial month and that was sorted by a simple email, fast response back and voila...I am now sorted with another month of unlimited data. Very impressed and will use again in the future if I'm in the same position or need portable wifi.

Sims 4 home are OK however activation is a nightmare, signal quality is strangely enough very poor and price is more than through 3 themselves, you get better service and signal through 3 themselves with a hub all at £12 a month

Ordered a SIM as my contract with Three had ended. Didn't expect it to work without issues but wow absolutely fantastic, straight forward set up and connected to all my old devices effortlessly without having to re-enter passwords

Bought this on 19th of December, received it quite quickly BUT wasn’t aware it would take one day 24 hours to set up then I started to have mobile data. It should expire on 21st but it stopped working on 16th. I paid for unlimited data but clearly it didn’t work that way

Sim card had great coverage, but sadly was expensive for the low quality of service I got. 1mbps average, sometimes 2. At least it functioned.. somewhat, albeit with a slow signal strength. Won't be buying again. I'd recommend Lebara's great unlimited data plans, they have high 50mbps speeds and at times uncapped 200mbps.

Best move I ever made good value for money and brilliant performance and service and no buffering
