Love taking these SIM cards abroad as it allows for the use of internet without having to buy a local SIM, just be sure to activate it in the UK before you fly and keep it in your phone, otherwise you will lose internet connectivity! Found out the hard way when I placed it into a travel router and realised my mistake. Even when purchasing the 10GB pack, roaming will still give you the 12GB limit so the data allowance is very generous, provided you are not abroad for very long or are not consuming heavy amounts of data via streaming etc. At around 8-10 quid per SIM (depending if you buy it on a deal) these are a nice cheap alternative to roaming abroad or even some local SIMs in some countries, the fact it works in 71 countries is great as it would cover most popular holiday destinations for most people! Only downside is, you will not be able to make local calls in said countries if you need that functionality. But you can call & text UK numbers no problem.

I've used these sims several times, without problem, just make sure you activate the sim in the UK before you leave an make a call or send a text message (or both to be sure!). Don't forget to change settings for apps like Spotify if you normally download over cellular, (those auto update playlists will quickly eat your data!) Worked perfectly in USA and Brazil However, be aware of third party sellers, I purchased my latest card thinking it was from Amazon, only it wasn't Amazon it was a third party fulfilled by Amazon, rather than getting a preloaded data sim, you get a sim with no mention of data, and a sticker on the back to call, text or WhatsApp to get your credit, the data never arrived and Amazon refunded me, luckily I had time to reorder. If you get the card pictured you are good to go, anything else I wouldn't trust it, as if you get abroad to find it doesn't work it will be costly to use data.

- Bought the sim card a few days before my trip to the US. Inserted it into my phone to activate it. Got the text messages with the number and everything, even downloaded the app. - Data seemed to work within the UK. However, zero balance was showing on my account (after registering the number, of course). - Contacted customer support, which confirmed that if my data is working in the UK, even though the balance is zero, it should work in Go Roam countries like the US (where I was planning to go and the reason for this purchase). - Went to the US. Data wasn't working (even though it is a Go Roam destination). Kept receiving notifications from AT&T or Verizon about how there is no data available and they can help me top up. - No data throughout the whole trip. Customer support informed that should I need data, I would need to top up. My explanation was that, since this is a pre-loaded SIM card and whatnot, I shouldn't have to buy more. - 6 days after contacting customer support again while in the US and sending them proof of this purchase, all I got was the following in an email: "Thank you for contacting us and sending us the proof as requested. We have attached the proof on the account." Needless to say, I still had no data for the remainder of my trip. It was my fault that I didn't heed the warnings of some other reviews on this page. I rarely leave reviews on products, but this time I felt that people need a heads-up should they decide to purchase this and essentially test their luck. I believe you would be better off purchasing a SIM from a different carrier that, even though it may be more expensive, would give you the peace of mind you deserve.

Bought for use in America. It was easy to register and saved me lots of money on roaming charges. I found the data worked absolutely fine and had no problem sending texts. I had a problem with phone calls. For some reason I wasn't able to make calls abroad. I tested before going away and after coming back where it worked fine but not in America. I would buy again when traveling as the main thing I need this for is the data.

We buy a few of these when we travel to the USA as we've full dual sim phones(not esim). I figured this review may help as there are comments about ensuring you activate these in the UK before you leave. I would say that may not be entirely true or necessary because we're not in the UK and we activate these in the Republic of Ireland before we fly to the US and never an issue. We can't even download the 3UK app either as it's not available in our country. I did once side load the app but by the time I'd downloaded and created an account the SIM activated anyway. You can always create an account without the app on a browser and track your data that way. You get 30 days so don't activate it too early but if you're heading for 2 weeks let's say then you can give it a try maybe a week or 2 before you leave to get over any tech gremlins in advance. I know we do this, ensuring we have roaming turned on and set SIM 2 as data, you'll need your main number just in case your bank texts you for suspicious activity. As the cap is now 12gb for each trip we have 2 x 15gb cards and a backup 10gb card because my partner blows through data like nobodies business. When the 12gb on the 15gb card expires we'll throw it away and put in the new one. Wasteful I know, but they don't offer esims. Lots of new phones aren't fully dual SIM anymore. Three UK don't offer esim on these card types or plan types. So if you're device is sim + esim see if you're own main provider can't replace your SIM as esim then this throway SIM might suit you for travelling and/or possible nefarious reasons.

My mobile phone operator charges an arm and a leg to roam with data when abroad. I've bought these SIMs before, and went with these again for my latest trip. They connect straight away, give you a lot of data, and seem very reasonably priced. Calling UK numbers is included, but note that calling numbers in the foreign country where you are travelling is probably not included as these, bizarrely, are considered international calls despite you being right there. But I find these a real reassurance for those times when you are out and about and don't have free Wi-Fi within range. The signal quality is dependent on the local operator, of course, and I did have times in the mountains when my phone had no signal despite a phone of a local being able to connect, but this could just have been my phone or the particular network my phone had attempted to join. In most places it worked well, and the cost of data was around a pound per gigabyte, rather than my home (UK) operator's pound per megabyte.

This was by FAR the BEST purchase I made before going to the USA! For £10, I had 10GB of data and unltd texts and calls. My own provider (Vodafone) does not allow me to use ANY data in the USA and wanted to charge me £15 for 5GB data and 100 mins and texts. This SIM offers the best value by far. All you have to do is download the THREE PAYG app and fill in a couple of details. This then allows you to clearly see what you are using whilst abroad. In 8 days, I used 6GB of data and was able to make calls and text my family back home without worrying I was going to be charged. The other great thing about this SIM is that you get to keep your own number while you use it - it sends you a message and asks whether you want to use the new THREE number or your own number. I had great coverage too, whether on wifi or 3/4G. Cannot recommend this enough!!

Tested in San Francisco and Los Angeles. Works well and speeds are quite good too, 50-80MB download. All you have to do is insert it into your phone and enable roaming in the settings. These work in Ireland and UK too. Three offers two similar SIM cards on Amazon, I did not know which was better so I bought both. They are the same, speeds are the same. You don't have to register them, but if you want to find out how much data you have left, you have to. Registration process was not really straightforward for either. The 12GB was harder to register, I had to dig around in the Three's site but once registered the website for it is more updated. The only part I did not like about these SIM was that Hotspot functionality is disabled on them. You can't share your Internet with the others.

En la descripción del anuncio pone que es un pack de 3 tarjetas, sin embargo solamente viene una. De haberlo sabido no lo compro.

getestet in Südamerika, USA, Kanada, Australien, Indonesien

Sehr einfach und schnell zu aktivieren. Einsatzbereich in vielen Ländern gegeben. Für mich ging es hierbei mehr um den asiatischen Bereich. Werde die Sim weiterhin nutzen.

Hatten die SIM Karte auf Mittelamerika Tour . Bester Empfang überall außer Honduras und Belize . Ich kann Sie uneingeschränkt empfehlen . Das einzige man kann keinen Hotspot geben damit!!!

Funktioniert ganz einfach weltweit. Würde ich jedem zum Reisen empfehlen. Getestet in Costa Rica, Panama, USA, Canada und Deutschland.
