$45 Sims4Travel Prepaid O2 UNLIMITED Data Plan. Unlimited 5G Data for use in the UK (Valid for 30 Days from Activation). Easy to Renew. (3-in-1 SIM Card). Stay connected whilst in the UK.

Sims4Travel hooked me up for the UK. Just wish i would of had them before i left the us. I left this same review on the Sims4Travel Vodafone sim. I talk about both sims. I purchased both at the same time and am fortunate to have found them.in the pictures is the O2 sim. but the wifi speed test is my simcard modem that is dual sim. this was the speed in this small town when the Vodafone and O2 sims were inserted and the connection was wifi to the laptop.the rest below is my experience with Sims4Travels which pertains to both their Vodafone and O2 unlimited data prepaid sims.Awesome product. I could not be happier. The best part about all this is the customer service is top notch. This company went above and beyond to get me running here in the United Kingdom. Their help phone number is beyond belief.I am writing this review with the aim of benefiting both travelers and my medical school colleagues who need to arrive in the UK with a functioning cellphone and plenty of data/Wi-Fi so they can stay on par with their colleagues, communications, and internet needs.I am a medical student from the United States. I flew to the UK in November 2023 to complete clinical rotations in the United Kingdom as part of my curriculum. Our rotations begin the same day which we arrive. Being properly prepared to switch cellphone carriers or make sure you have a plan in place for adequate Wi-Fi if needed will save you from a headache as you start the rotation in the hospital the same day you arrive. There are 300 or more Americans and Canadians from my school in the UK at any given moment. Hopefully this helps some of you and our colleagues that followMy visa application was pricey and came with a Sim Card. I thought that I had my phone situation solved “sorted.” I was wrong. The sim was slow and only allowed 2gb of data total. My apartment also came with Wi-Fi, but construction is mainly concrete where I am, and our Wi-Fi was only functional in our kitchen. My colleague, who also arrived in November, was assigned another region in the UK and his situation was more limited. His two cellphones were all locked. He was looking at having to buy a new phone. His apartment Wi-Fi was only functional from 5pm-8pm. The rest of the time it was lagging to the point it was unusable. You don’t appreciate what you have until you don’t have it.We both needed solutions to our cellphones to allow us to communicate with our preceptors and Wi-Fi that would allow us sufficient data to cover our medical resources online and also fast enough that we could attend the mandatory, weekly zoom/meetup meetings.With Clinicals having started the day we arrived in the UK. we were already going to be a week behind in studies. Playing catch up is never easy. I asked the locals what they used. some recommended Vodafone unlimited data plan and when you go to costa coffee, show them you are with Vodafone, you get a free coffee.I looked on Amazon so that I could have the Sim Cards delivered. (My recommendation is to get a proper Sim before you ever leave the country. Also, the Sim Card that comes with an expedited Visa should not be considered a solution.) I found the Sims4Travel site listing Vodafone and O2 sim cards that were prepaid and had unlimited data. I then checked their cell tower strength in London, our locations, and overall reception in UK. Both Sims looked like possible solutions to meI purchased both as I needed something that worked ASAP. I also purchased a sim card router to put them in. I showed my colleague who immediately purchased the Vodaphone sim and a mobile router the size of a phone that had a 13-hr. battery for just over a hundred bucks. His arrived first and He tested it in the basement. Using the sim card modem he was streaming a video on the laptop while simultaneously being in a what’s app video call with me. He had no connectivity problems... He was stoked. He had a functional solution. He just carries his sim card modem in his pocket, and it gives him wi-fi everywhere he goes and to multiple devices at a time.my experience with the customer support really means a lot to me.My Vodafone sim card arrived a few days after my buddy got his. I had ordered a different modem than my colleague and I was struggling to figure out how to set it up. I contacted the modem support chat who said, “Vodafone should work in the Wi-Fi 6 modem, please reach out to the carrier. Sims4Travel had a post card in the package with online activation, and tech support email and phone number. I called it and there was an immediate answer. He went through the settings with me while I was on the phone. He sent me a screenshot of how it needed to look. We eventually got it running. Two days later my other sim arrived, O2-sim. (I plan to use one sim in my phone, but my modem can also run dual sims. if needed, I can put both sims in my modem and then my connection becomes really fast... I called the Sims4Travel, and I got the same guy, and he remembered me. He treated me as a friend. Far better than I have ever been treated by a phone company in the United States. We initiated the 2-hour activation, I received a text that the sim was now active. An additional 3 hours passed before I tried the Sim in any application. At this time, I received a text not from a machine, but the tech support I spoke with prior, asking if the Sim was functioning properly. I confirmed that it was. Costumer service is top notch.I believe for those traveling to the UK, who require cellular and data connections, this product paired with its customer support is the best. Also, to the medical students coming to the UK, make sure you know if your carrier covers the UK and at what rate. I had other colleagues with coverage that their phones charged an additional connection fee of $5-10 per day. If you are in this situation, I would highly recommend that you sort this out before you leave the United States/Canada. It would have saved me a lot of time my first week of clinicals. If you are like my colleague and myself, not only looking for a solution for our mobile phones, but we also needing a mechanism of getting Wi-Fi without signing a cellular contract. These prepaid data sims became the solution for both. They will work in unlocked phone and the sim card modems. The costumer support is better than any other company I have worked with. I wish that I would have had this sim before I left the United States as it is an essential precaution for me as medical students. The loss is minimal if not needed and an essential time saver if needed.

Needed to purchase a Sim card that was valid in the London area, my oldest granddaughter traveled to London for college courses. Wasn't familiar with how to activate the SIM in a dual Sim iPhone. I had the good luck of contacting Richie Lannon, the Managing Director of Sims4Travel Ltd. He was able to answer all my questions. Walked me through the process, everything went perfect. The O2 unlimited Sim card has worked out perfect for my granddaughter. Perfect product and great customer service experience. Would wholeheartedly recommend Sims4Travel to anyone looking for trouble free experience.

This is a great value for iPad use while vacationing in the U.K. We used it almost everywhere we traveled in Scotland. However it’s important to know that you must activate it through the O2 reseller, in this case Sims4Travel — O2 cannot do this for you even though you’re using their network. We activated via e-mail on a weekend, so it took a few hours for them to respond, but from then on no problem.

This didn't work.I brought it to a professional who tried it on 5 different phones, and it didn't work.Ended up having to buy a new one in person at the train station.

I tried to use this product for a week long trip to Ireland. Upon installation it takes 24hrs+ to start using it and you need access to Wi-Fi. I ended up giving up and payed for the more reliable travel service plan from my provider. Thankfully my rental car had a GPS included or I would have had a really tough time traveling. so don't bother getting this product for short trips.

Took forever to activate then I figured out it was data only my mistake it was over priced. Bought this to use on trip to UK everyone here said I paid way to much

What a great little device helping us save a bunch of money. We use Rogers in Canada and they offer wifi calling which allows you to use wifi data to eliminate Roaming fees.So the 3 of us just arrived in the UK where normally we would buy a paygo sim from 3 but we are using a little tp link 4g modem and this unlimited data SIM for a month. We activated it after landing and we had it up and running before we left the Airport. We did have to send an email using the airport wifi which was easy. So now instead of 3 phones x $15/day for a month we have this investment and a device we can use over and over for years which easily fits in one of our bags. This combined with wifi everywhere is super convenient and The big plus compared to buying local sims when you travel is we keep our phone number and talk and text as usual wherever we are. Great plan!

Reliable ,very happy with itWorked well in NetherlandsHelpful advice from company in setting it upgood coverage , good value.I can recommend

Good Customer Service: they forgot my mail but then they solved the problem and activated my Sim Card in an hour with a call.I used the Sim with a travel router and I could work online without any troubles.

We purchased this SIM card for our trip across England and Wales. We activated the SIM on arrival, as the instructions said to, and it initially worked great. We were able to use it for about 2 days and then the SIM card stopped working once we got into Wales. We were unable to get on to any cellular network and the data also did not work. We tried resetting all the settings and there was no change. We eventually had to buy a new SIM card from a different provider in order to get service. We are very disappointed with the performance of this card.

Worked for about 1 day then quit.Visited O2 store and they said they never sold this type of sim.Completely unknown to them.Bought a new sim from O2 and it works fine.Returned the SIM card to Amazon.
