Three UK Prepaid Europe SIM with up to 12GB data for 42 countries for 30 days

I shopped around for an overseas SIM card for travel in the UK and decided on this one. I didn't know if it would work or not, but I was tired of paying $10+ a day for my Verizon travel plan, which slowed my browsing WAY down after 250MB of use. I had a spare iPhone SE so I figured I'd try it out.I activated it prior to leaving overseas, and I was surprised that it picked up a T Mobile signal here in the US. I didn't want to have it go wonky on me, so as soon as I knew it was working, I shut off my phone. Upon arriving in the UK, I turned my phone on again and...viola! It worked!I had no issue with it for the week I used it. I wasn't able to use it while in business meetings during the day, but in the evenings, I had no issue at all with 4G browsing...streaming video, sending e-mail and the like. There were a few places on the train trip between cities where I lost signal, but that's because I don't think there was any signal there in the first place.I turned off my phone upon leaving the UK but figured I'd try out the SIM in the US for my mobile passport app. Once the plane touched down, it picked up 3G T Mobile, then it went to four bars, 4G AT&T, which I had for the remainder of my trip in the US.I finally reverted back to my US phone in the airport, but had to give major kudos to how well the SIM card worked during my trip.The only drawback I had was the lack of phone to US texting/calling capability. Maybe I just didn't figure it out, but I couldn't call or text US numbers, and vice-versa, they couldn't contact me. That said, I could text with friends who had iPhones from the US, which I thought was interesting - particularly since they were texting my OTHER iPhone (my US one) but the texts were showing up on the iPhone SE I was using, even though it's not on any of my calling plans in the US (we replaced it but kept the phone as an unactivated backup). I ended up using Facebook Messenger for my non-iPhone friends, and so it worked out, but that's just one thing to keep in mind as you use this in your phone.Overall, I was super happy with it and it was a bargain compared to what I normally pay for overseas phone service!

I bought this card to work with my unlocked BLU phone. SIM card arrived and activation was easy from the US. I made a call to our UK hotel to confirm a few things and the call worked great. Less than 5 minutes.I then tried to call the car rental company in the UK and the call would not go through. It said I had to "top-up" and that I had no data/minutes/texts left. So, I'm not sure what happened. It clearly states you have 9gb data and minutes/texts outside the UK, but now there is nothing on my phone and I have to pay to "top-up" to use it. I would not recommend.

UPDATE: After about 2-3 days, the content filter was able to be turned off and I can access the entire internet now. I gave an extra star and honestly still highly recommend this sim; it’s the best bang for your buck. I’ve done a lot of traveling around the world and this is the best price i have ever seen for this much data by far. I’ve also had great reception and speeds the entire trip so far in Munich (Germany) and Oslo, Moss and Son (Norway). I’ve had 4G with 5 bars almost the entire time and averaging about 30-40Mb/s.ORIGINAL REVIEW: So let me start by saying, this definitely works and I have received the 12GB data and actually unlimited call and text. I activated it in the US using the instructions on the back and it worked almost immediately and I have been using it the past few days in Germany and Norway with great reception and data speeds.That being said, the data service has a built in “adult content filter”. I went through all the steps to turn it off (it even confirmed the filter is off in my the account), but it still won’t budge. I spent some time on the phone with customer service and he assured me he reset it and within 24 hours the content filter will be turned off. It’s been 24 hours and i’ve tried multiple times again to turn the filter off. Nothing. I’m blocked from a site I need and it seems I will be blocked from it unless I get another service. The site I need does have some adult content so I understand why it’s blocked, it’s just extremely inconvenient and something I wasn’t planning on.Besides the filter, everything else works as advertised (hence the 3 star review and not 1 star).I will update my review if anything changes.
