MOST SIM - T-Mobile USA SIM Card 18 Days, Unlimited High Speed Data/Calls/Texts, T-Mobile SIM Card US United States

I was nervous ordering this because of mixed reviews but I weighed it all up and asked questions on here first to double check. I ordered early to give me time to sort the Activation out.All the instructions were straight forward and I waited 2 days for activation which was fine.The card comes with a PIN to release your other SIM in phone so that was handy. I put in SIM night before flying at home to check it was fine and then switched it over before landing on US.My phone is an iPhone 6s and I had no issues using in Miami and New York US.I needed the data and I used 32gb on my holiday for Google maps, UBER, Whatsapp, Whatsapp video call (to UK), Facebook, Instagram, airBnB, texting.... lol you name it the lot. It all worked. All my contacts were still the same on phone when I switched SIM too.I was very happy to have this SIM and has saved a lot of money for me. I would definitely recommend this product and I will definitely be buying again.

I used this for a 14 day trip to Florida with my Samsung Galaxy S7 Edge That was on 02.I did lots of research and basically found out i had 3 things to do before leaving the UK.- Samsung products are apparently locked in the box to work in the UK only - Making just 1 standard 5 minute phone call stops this- Unlock my phone so it can work on a different provider (t mobile) - rang up 02, got an unlock code - borrowed a friends (non 02) sim card put it in my phone and typed the unlock code in- Register the SIM Online with MOST SIM (described in the instructions)Filled out the online form 3 or so days before, got into america turned the phone on with the new sim, and it started working perfectly, did not receive any spam texts or phone calls the whole time i was there unlike some of the other comments below.+ Came with Sim Remover+ Came with Instructions+ Came with All 3 types of Sim's+ Zero phone calls/texts+ Worked on time as expected+ Easy to set up onlineWould highly highly recommend this to anyone who is thinking of going. Hopefully my review will convince other people to try it and hopefully you won't have to look up as much information as i did.Saved myself over £70.. when 02 wanted Around £110 for my 2 weeks away.:)

I bought two of these to use in an iPhone 6S and OnePlus 6. Activation was easy through the website an I did this a week before I travelled to the West Coast. You'll need to be careful entering the SIM number and the phone IMEI since each SIM is activated for that phone.We used these mainly for data, so wasn't that bothered with voice calls. Data worked well in Washington state, Oregon and California. We used Google Maps, WhatsApp phone calls, Facebook etc with no problems.The downside was that both SIM cards have re-issued numbers, so one had several automated phone calls from Nevada, which we didn't answer then just blocked each number so it wouldn't bother us again.Would have given it 5 stars apart from this.

I ordered this product to use in an unlocked iPhone in the Manhattan area of NY. I did all my research (regarding compatibility) prior to my order and my phone was compatible with the plan and area. I received the SIM with no issues and had no difficulty activating per the instructions. When I arrived in NY and put in the SIM: It didn't work. I followed all the instructions to the 'T' and the card still would not work. I contacted MOST SIM customer service (which can only be done by email) to correct the problem. When MOST SIM investigated they found that the SIM had 'already been activated before they (MOST SIM) set up my plan'. That, to me, translates as the SIM was either used or stolen or jacked etc. MOST SIM did refund me but this did me NO good when I was stranded at the airport with no phone and NO way to contact them as you have to email them. Strongly advise not buying.

The card arrived very quickly after order. All the instructions were easy to follow. The activation happened on the requested date and stated time. On arrival in USA the card worked immediately on Huawei P Smart for both calls and data. I am very satisfied with the service. It would be nice to be able to get an area code appropriate to the area visited but the out of area code did not present any problems for either sending or receiving calls or data. Very good show, SNW

Went for a three week road trip holiday with my family. We started in LA then went 2700 miles all round the south west. I wanted to have emergency phonecall capability, be able to make calls to hotels, restaurants etc and maintain social media connectivity for the family. Wary of being bankrupted by overseas call and data charges by my UK service provider I paid for a 21 day US sim with unlimited calls and data. Followed the straightforward instructions with the purchase and found on landing sim functioning perfectly as described. Was able to tether phones of wife and son to my phone so they could use my data as we travelled around much more convenient than relying on public WiFi . All in all an absolute must have for any road trip holiday and unless money is no object only alternative to using tour uk sim and remortaging the house. Highly recommended.
