Three 500GB Data SIM – Uncapped 5G Speeds – Preloaded EVERY MONTH Until 8th OCTOBER 2025 – No Contract – Plug & Play for Business Broadband, Routers & Phones

I have purchased a few of these Data Sim's over the past few years. All running on the Three network. I found them to be fast and reliable. So. IF...you have a decent strength signal from the Three network, these Data Sim's are great value for money. Delivery was next day. Excellent product

I bought this Three 500GB 5G SIM to use in a portable WiFi router at our martial arts academy and for travel across the UK — and I honestly wish I’d discovered it sooner. It’s preloaded with a huge 500GB of data every month until October 2025, which is phenomenal value, especially for anyone relying on mobile broadband for work or streaming.What I loved straight away:• Instant Activation: Pop the SIM in, wait a few minutes, and you’re online. No contracts, no registration hurdles, no top-ups to fiddle with. It just works.• Speed and Stability: I consistently get fast, reliable 5G and 4G coverage, especially in South Wales where we don’t always have the best signal. It’s been stable enough for Zoom meetings, streaming video, and multiple devices running at once via the router.• True Monthly Reset: Each month, like clockwork, the data resets. No hidden catches or rolling renewals — it’s exactly as advertised.What to keep in mind:• It’s a data-only SIM, so no calls or texts — which is perfect for routers and tablets, but worth knowing in advance.• If you’re using this in a phone, you’ll want to turn off automatic updates or background refresh if you’re a heavy app user — 500GB is a lot, but with 4K video or large downloads, it can disappear quicker than expected.Compared to pay-as-you-go options, this is dramatically better value. You’re essentially getting business-grade data at a fraction of the cost of regular rolling contracts, without the commitment. And unlike many data bundles, there’s no daily limit throttling — it’s full-speed access the whole time.Final verdict:If you work remotely, travel often, or just want a backup internet source that won’t let you down, this SIM is a no-brainer. It’s plug-in peace of mind until 2025 — and that’s rare these days.

Great little sim, slight issue, tried to put it into the sim tray on my ipad M4, the new pads don't have sim trays!!Emailed the company and they sent me a QR code to use as an e-sim, problem solved! 500gb per month = unlimited data really, I challenge you to use that amount of data in a month, and it automatically renews every month, in this case, for just over 2 years. Absolute bargain.

This SIM deal is awful. Sure, it's cheap, but it's definitely not cheerful. Somehow, 3, the (near) equal worst network in the UK, have exceeded their dismal reputation. Occasionally they deliver respectable data bandwidth, (I'm based in the premium inner-city suburb of Islington, so you'd think they had their best network infrastructure here), but almost always, the upload rate is so bad that the connection fails. My (various 4 and 5G) phones do not recognise that there is a server ready to respond - and they time out. This is not building or exact location-specific. It's really poor and unstable all around the area.Let me spell this out... If you need a SIM to do any professional activities, then this is definitely not for you. You absolutely cannot do video calls, because the network is so unstable, that your call will drop out and cut off. If you want a short-term SIM for downloading videos or large amounts of data in the background - and don't mind restarting the downloads multiple times, then (maybe) this deal might work for you.The bottom line is, this is a seriously low-grade product/service and you get very little for what you pay.

Worked instantlyNo issuesWell worth its moneyEasy to set up

So far working well, I have this connected to a personal hotspot and it works wellYou simply put it into your device and away you go, you can not make calls unless you use kinternet call services as this is a data only SIM card, you can the. Just simply get it unlimited texts and calls from elsewhere for around five to six pounds and it will work out to 500gb data plus your unlimited calls anod texts for just approx £10..Easy to use and set up you don’t need any additional set up just the sim you can use it on a duel sim or you can use it for your hotspot.

Use this at a site where there is no land line. The only limiting factor is that the local phone mast has a restricted data bandwidth but that's not the product's fault and I've tested it against O2, Vodafoen and EE and it's most reliable for our needs.
