Pre - Loaded Data SIM Lasts up to 24 months
I bought this to use when on holiday around the UK. Fast delivery from the seller, very simple to set up, I just put it into my TP Link router and away it went. The two years start from the date it is first connected to the 3 network. Setting up an account with 3 so that I could check the data useage was a bit more complicated. You have to use the internet connection of the sim card itself to set it up, once I worked that out it was simple. Just one other thing as with most sims you MUST use it at least once every 180 days or it will expire early. As I intend to have it running as a background backup to my home BB that should not be a problem. As for the 24 months life? well time will tell if thats true. At the price it would be good for ioT stuff as well if you dont want to be tied into a contract. Watch this space for updates later ;-). UPDATE 1: Its been running for over 12 months now and still working well, my expiry is August 2025. As I said above I leave it on and connected 24/7 at home to prevent the sim "expiring". So far very pleased, I will buy another in 2025 as long as its still available and the price is not too high. 5*. UPDATE 2: 19-3-2025, Its now the middle of March 2025 and the sim is still working fine and surprisingly I still have 9GB left, very highly reccomended. UPDATE 3: August 2025 the sim went the full 24gb data amount and I ran it out just a month before the two years were up. Brilliant!

Best value for MiFi/laptop 4G/LTE use on the road
Note: the new 24GB version is probably the best value right now, 2x more data for about the same cost - and lasts 2 years!!! Is there anything cheaper (just over 1 quid per month)! If you are regularly on-the-road and you need to use Internet on your laptop - rather than depend on various WiFi points, having your own LTE link is preferable. While most Cloud/FON/hotels/cafes/etc. connections do work - they are generally open/un-ecrypted and sometimes a hassle. For 2 quid (or so) a month - it is a joy to just connect directly and - 'boom' - you are on the Internet! Of course, nothing stops you to use a WiFi point instead, but if you need it - it is there. I used it first in a MiFi (EE-branded unlocked Osprey) then laptop with LTE connection in towns every time. I also used abroad (Europe) roaming at no cost with decent performance - naturally 3G+ only (not LTE). But I don't think any other UK providers provide free LTE roaming abroad. Still it saves you buying a local data SIM which may be problematic sometimes even in towns. It is particularly nice if your laptop/tablet/etc. has WWAN already installed (or WWAN option possible) - just insert the SIM and there you go. No registration required - great - and you can keep track of data left on 'My 3 Home -> Data Allowance'. It seems to update in almost real-time. If you only use it sparingly, it lasts 12 months, but if you really need to use it all in 1 month (e.g. moving house) then you can. Not particularly cheap - but still cheaper than a contract and any silly data deals are usually short-period (e.g. 100GB EE, etc.) so not really a fair comparison.

Connecting glitch but now working
The 24gb sim looked like good value but would not connect to data in a tablet or old phone. Eventually I started a chat with Three, and was given the number 500 to call from the sim. They discovered that their engineers had to unlock something, and did this, and it is now working fine in an android tablet and a dual sim phone. If yours does not work Three appear to be able to sort it out. I have not travelled with it yet so can’t comment on that aspect. I have now travelled with this sim and have a couple of observations. 1. I tried to use it as a hotspot from an old android phone and all that happened on the connecting device was a site saying Three was blocking porn. This happened in several countries, and I have not yet had the energy to ask three what that was about. The phone still provided a direct data connection, just no hotspot. 2. I was away for 3 months and used the sim sporadically in various countries. Towards the end of the trip I received a snarky message from Three saying you cannot use the sim outside the UK for more than 2 months without returning to the UK. I did not spot that in T&C, which I thought I had read. I have taken away a star for these travel related issues. It is still reasonable value for the coverage in the countries available

No use for travel. "Fair Use" policy is anything but fair.
3 will turn off this SIM either within a few months, or if you only use it abroad. Don't bother with it. If you're thinking of buying this for use on holiday during the “24 months” artificially limited lifespan, then think again. What is your use case? If you have a UK phone, you're likely to use your phone's SIM for data in the UK right? But you buy this SIM to get wifi / data when abroad, right? Well it doesn't work like that. Or it does, one time - then 3 flip their lid. You need to use this SIM in both the UK and abroad, because if you never use it at home (UK), but only use it while on holiday, 3 start claiming it is against their fair use policy and turn off your SIM. They also use some mad passive aggressive language in their emails. "We will not lock any devices you buy from us" - mate, I don't buy your devices. I've not used this in the UK as I have a giffgaff sim in my phone - but i use it in a WiFi dongle while I'm on holiday (Europe) - then 3 say 'you only use this in the EU, not fair boo hoo'. 3 take your money for a limited lifespan product, limit its use case, then turn it off when if don't use it in the UK. Beware.

Think twice before you buy this sim card if you are not in uk!!

I bought this card to use in the US and in Europe. Its suppose to be good for an entire 365 days so we shall see if it lasts until August 1, 2020 (if I use data sparingly) 1. Easy to install. I just popped in the new sim card. Turned on data roaming and in a few seconds I was getting data in the US. I have been using it for 2 days now and it is working flawlessly. 2. I tested out its hotspot capability and my wifes samsung was able to link to my hotspot. So that works too. I will report back and let you know how it performs in the long run...and on my multi country trip to Europe Update. The sim worked flawlessly in the US during the 2 weeks I was there. Once in a while i had to restart my phone to wake it up. Update. I arrived in Germany. I RESTARTED my phone, turned mobile data ON and turned Roaming ON..and I got connected. So far so good. (Update) I am now in Italy and the sim is working although not in every spot. Seems like some of the more remote places like up in the mountains while hiking..no data. But in the city no problems. I stopped into a vodaphone store to price compare. They had a deal...2 sim cards...ONLY ONE month service...lots of data...60 euros. A LOT MORE EXPENSIVE!!! (Of course they are in ludington phone calls which this card does not) (Update) I am in Switzerland and still am getting decent connections in the towns and cities. Forget about signal if you are hiking in the hills or away from towns. It works well enough to watch a YouTube movie. I'm using it mainly for Google maps to find train/bus connections and to Google tourist attractions for info and to message my wife if we ever get sepatated So far so good. (Update) works in Metz France. Poor connection outside city In remote rural areas. When I pass the border into a new country I keep getting text messages saying I have a maximum of 15 gigs of data with this sim. Not the 12 gigs advertised. Not sure which is correct (Update.) Working in Luxembourg and Begium. In Luxembourg ORANGE STORES were selling data only sim cards...9€ for 5 gigs for 30 days. So a little better deal than this sim But in Belgium ORANGE was 15 euro for 4 gigs plus 4000sms and 50 mins of calling. So ORANGE was a better deal Works well in Amsterdam Works throughout Spain UPDATE OCT 4, 2021 Going to Europe again so I bought this same 365 day card..12 gigs of data. I tested it in the USA I shut off my Samsung. Removed my old sim Inserted the new sim I just got. Turned my phone back on Made sure mobile data was on And IT CONNECTED RIGHT AWAY. So far so good If it works as well as it did in Europe as it did 2 years ago, I won't have to keep buying sim cards at the end of every month in EU. This card is suppose to be good for One whole Year (total if 12-15 gigs) So if i just use it for maps and sending messages. I should not run out of data even if I am in the EU for 4 months UPDATE DEC. 6, 2021 Just retuened from 2 months in Europe using my newly purchsed sim. I visited 3 countries..Greece, Italy and France and this sim worked like a charm in each country. As soon as the plane landed it texted me to let me know it had switched countries. Its not alwauys fast and occasionally in remote parts of Sicily the connection was poor to none... but it allowed me to buy train tickets, use google maps and google tourist attractions on the go. Now to see how long it will last. Too bad it doesnt work in Thailand which is where I am headed in a month L9ving it

I went to UK, Norway and Iceland recently. the card worked very well in all those three countries. The difficulty came when I tried to activate it following instructions that came with the package. Fortunately, their tech support came to help quickly.

I loved that you can buy it, hold on to it for a while, stick it in when in the vicinity of UK ip space and it just works while in UK. Have to come back here to Germany it still just works with the UK number associated with SIM. If this sim works while I travel thru Europe to other places it might be the most valuable overlooked option available. So nice not needing customer service, take tons of selfies or give a scammed wet dream job all your info just to have a backup sim when you travel primarily for directions and built in apps. No clue if the service is the best everywhere though so I may have gotten ahead of myself because of ease of setup and quality data I'm using to write this very review! Recommend over locamobel or Vodafone so far.

初めてイギリスに渡航する前に購入。現地で何も分からず困ったときにWiFiにアクセスできたため、非常に助かった。値段もお手頃で使い切りタイプのため、誰にでもおすすめできます。
