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.

Great deal for the money, perfect for LTE tablets/laptops
I bought this data sim to use with my LTE version of Surface Pro 2017. Since I wasn't willing to take on another monthly contract just for my Surface I looked for options without a monthly fee. This was the best option that I found and I believe that it's the best one out there at the moment in the UK.24GB is plenty of data and will last months when used for normal internet browsing and emails if you avoid videos and large file downloads. So far after a month of almost daily use I still have almost 23GB left.I also like the fact that the data can be used over a period of 2 years, which is plenty of time. The only downside (and the reason for 4 stars instead of 5) is that once you run out of data, the top ups are a bit pricey and any unused top-up data expires after 30 days. I would really like for top-up data to last for 2 years, just like the data that's initially preloaded on the card. I think that once I run out of the 24GB of initial data I will just buy a new card, since that works out cheaper than having to top-up the existing one, which is a bit of a shame.In regards to connection quality, I'm getting excellent coverage and speeds in Glasgow. Speeds above 30mbps are nothing unusual and I've measured 60mbps on some occasions.Overall, if you're looking for a data card for your secondary mobile device (i.e. ipad or laptop) and you don't want to pay any monthly fees then this is the best option out there.

Works Great!
I use this 24gb Data SIM in my ZTE Travel Router and it works great.I activated the SIM once I had created my "My3" account (as detailed in the instructions) and popped it into router - all worked immediately with no hassle.I have used a GiffGaff (O2) SIM previously and that was trickier in that you had to set up the APN etc. That's not necessary with this '3' SIM. This one is also more economical as the data lasts for up to 24 months whereas I was topping up my GiffGaff account every 30 days. I seem to get a good signal in most locations I travel to and transfer rates are excellent.I hope to be able to try the SIM out abroad in the summer (if we can travel). Once the data allowance is used up, I will simply buy another SIM (as top ups are more expensive). In the meantime, I am very pleased.

At least the 4G of my Kindle Fire is in use again.
As we are going away for a Spring Break I decided to buy a 3g sim for my Kindle Fire HDX. Some kind person mentioned this sim worked in a Kindle Fire so I ordered a trio one as I did not know which size sim I needed for the Kindle Fire.Our Spring Break is at Minehead first for a few days and then we go on to Devon Cliffs, Sandy Bay for a week. Minehead is ok for WiFi and internet but Devon Cliffs post code EX8 5BT is not. All other coverage maps said "No No" for Devon Cliffs but 3 said postcode EX8 5BT was in the 3% they have not covered but the map shows possibility of 2G in the outside air. This is how I chose 3's sims at least we might have one phone working.I also had just bought a Mobile WFi and found that that needed a standard sized sim so I ordered 2 standard size 3g sims. The standard sized ones were cheaper.When they arrived I discovered had been sent 3 x 3G Trio data cards which were identical so it meant I had paid more than I should for the two so-called standard sized ones as they were the cheaper trios.Now the standard size has gone up to over £13.Completely confused now I punched out the Nano size out of one of the trio cards and put it in my Kindle Fire and managed to activate it without registering. I put a standard sized sim from another Trio card into the Mobile WiFi and charged it.Of course at home with good internet the 4G Kindle Fire achieves 4G very easily and I found it did the same using the new sim instead too.The Mobile WiFi does not mention 4G in its description but my laptop and a Kindle Fire without 4G worked well on WiFi using the mobile wifi. For a few minutes I put the 4G Kindle Fire on to the Mobile WiFi as well with its own sim out of action and I used all three devices at the same time with no loss of speed etc..I am still a bit bewildered wondering if I was sent the actual 3 trio sims this review is about or whether I was sent three different trio one.I decided to send for 2 more standard sized sims the ones now priced at £13-70. and those have arrived as trios identical to the others I already have.My daughter wants a couple for her son's Ipad in case we find Devon Cliffs' WiFi is not as bad as we are led to believe so we decided to order two of these Trio's again at £12-75 and see what we get sent this time as these still cost less than the others.The mobile wifi and the sim has changed my Kindle wifi devices into 3G modelsAfter our break I will add to this review about what internet activity we got for the sims.

Virtually impossible to check the amount of data used/remaining on newer sim cards
whilst this is easy to use and provides reasonably good mobile internet, if you want to check how much data you have used / left or when it will expire its virtually impossible since they stopped assigning a mobile number to the SIM cards. I have had many of these in the past and they always had mobile numbers printed on them .... but not any more, just an ICCID. This means you cannot use the app, the website or even the online chat to check the data status - they just tell you to visit a shop which is not at all comvenient - so beware if you have a newer one without a number on it - keep track of when you last used it (must use at least once every 180 days) and how much you are using ..... I have mine in an iPad and I hope the usage that is showing me is correct - time will tell.

works very well, with a little difficulty to start
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'm giving thus full blown stars bc 2 EZ
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.

16か国、全く問題なし
・Android(ASUS) / iPhoneにて使用・わしは1か月のヨーロッパ旅行で以下の国やエリアに行ったが、設定も楽で、速さもストレスなく問題なく使用できました。もちろん多少電波が弱いところはあるけど、フィンランドの田舎で山奥の家の中や、国境の何もないところや山間部くらいで、概ねつながっている状態でした。・対応エリアはサイトが見づらいのはさておき、記載の通りで、対応外の国(ベラルーシ、ボスニア・ヘルツェゴビナ、セルビア)に入国したときは、SMS通知は来るもののネットはつながりはしません。・むちゃくちゃ安くはないんでしょうが、わしのように多めの複数カ国を回るならおすすめ!- デンマーク(コペンハーゲン)- ノルウェー(オスロ、フロム)- スウェーデン(マルメ、ストックホルム)- フィンランド(トゥルク、ウーシカウプンキ、ピュハマー、ヘルシンキ)- エストニア(タリン)- ラトビア(リガ)- リトアニア(シャウレイ、トラカイ、ヴィリニュス)- ポーランド(クラクフ、オシフィエンチム)- チェコ(キヨフ、プラハ)- スロバキア(ブラチスラバ)- ハンガリー(ブダペスト)- フランス(パリ)- ルクセンブルク(ルクセンブルク)- ベルギー(ブリュッセル)- オランダ(ドルトレヒト、アムステルダム)- ドイツ(ケルン、ベルリン)*( )内は主に滞在したエリア
