MOST SIM - T-Mobile USA SIM Card (21 Days Unlimited)

Used this product in Florida for 28days and it was pretty much faultless. As said in previous reviews you do get the odd call from strange numbers but i only received maybe 3 in total and as I was using it mainly for data I cancelled incoming calls on my phone. I found the data perfect, perfectly quick (which was what I was worried about) and no loss of signal.I setup the phone as per instructions and picked the date I wanted to it to activate when I was away. By the time I woke up on my 2nd morning, the day I had it activated for, i had full signal.I was able to use my mobile like at home for the full time and I would definitely be getting one of these again when I travel to the USA.

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.:)

This was really important and useful to our holiday - it meant we could use maps to travel, access timetables etc. Everything we needed to do we could do because of the unlimited internet access. We got another cheaper "calls only" SIM for my wife to keep in contact and used this one for all the internet needs. It also allowed us to video call back home and also access online apps for Disney / Universal.It worked perfectly in San Francisco, Sacramento, Santa Barbara and Los Angeles and it even worked in Yosemite National Park (in the main park area by the falls / El Capitan) although there were spots in the park such as where we stayed (El Portal) where it didn't work but that's to be expected in remote places.This was worth every penny for me - saved a fortune compared with using "roaming" and guaranteed no "surprise" charges once you've bought it. Will do this every time if I'm lucky enough to head back to USA.DO follow the instructions carefully to activate it at the right time and ensure your phone (mine was iPhone 7 Plus) is unlocked to use the SIM BEFORE you go. If you follow the instructions it should work fine.

I wish I had know about these pre-paid SIM cards earlier as I am often in the USA visiting family as well as holidays and my UK mobile phone bills ends up being enormous. I brought this on the recommendation of a friend for a 5 day visit to NYC at the end of January. It was fantastic. Arrived in the post very quickly. Very easy on the website to set it up and as soon as I arrived in the USA and put it into my spare iPhone it was up and running. So useful for using the map on the phone to get around and was able to call and chat with family members in other parts of the USA. Had to go to Tampa a few weeks ago and got a 7 day SIM card, again worked like a dream. Have now purchased a 21 day one for a family trip to Honolulu in April. Can't recommend it highly enough.

This item works well, and certainly saved us a lot of wasted time on our recent holiday in the USA. The SIM has to be linked to one specific mobile however before activation, so sharing it is not possible. In some areas, such as New York City, we only had GPRS data, so using Maps was a slow process, but it did work. In Chicago, 4G worked flawlessly and we could surf to book restaurant & hotels easily.Overall a very good product for the price, but setup a bit complicated, and the lack of 4G in some areas would lead me to give it 4.5 stars if I could.

I bought this for a 10 day break and thought maybe it’s too good to be true. Before flying out questions I had were swiftly answered by the MostSim team and gave me confidence I made the right decision. It was the easiest thing in the world. I activated it the day before Arriving in Florida and it was amazing. Before I got off the plane my phone was pinging away with messages. I never had at connection issues and had access to data with no problems at all. The best find I’ve ever had and I have encouraged friends to do the same.

When I landed at JFK, I switched it on - having activated it as set out in the helpful guide - but it wasn't working: no voice or data. I tried to call our hotel and was switched to the T-Mobile help line. The woman tried very hard to work out why the sim wasn't working and brought in someone else on the call from another section to see if he could help. However, after 30 mins, we were no further forward and it was clear that she couldn't help. Interestingly, neither of the people had ever heard of Most SIM.I looked for contact details to get tech support, but couldn't find anything other than an email address - and, given that I had no data, it was kinda hard to send an email!!!In the end, because I needed data, I ended up going into a Vodaphone store - they had the cheapest on-the-ground offer for tourists - despite someone in a T-Mobile shop telling me that I wouldn't find a deal of less than the $60 they were about to charge me.Moral of this story - if it works, great! Many people here are happy. If it doesn't, you've wasted your money....

Ich war geschäftlich für 2 Wochen in den USA und habe mir dafür diese SIM Karte für 40€ gekauft.Da das Internet unlimitiert und super schnell war habe ich nicht mal das Hotel WLAN benutzt.Auf dem Screenshot sieht man alle wichtigen Informationen zur Geschwindigkeit.Insgesamt hatte ich ca 8 Spam Anrufe in 14 Tagen was sich leider nicht vermeiden lässt da die Rufnummer immer wieder benutzt wird. Auch war die Registrierung z.B. bei Uber mit der Nummer nicht möglich da das schon mal jemand gemacht hat. Hatte dafür aber noch ein zweites Handy mit deutscher Nummer. Sollte man dran denken wenn man in die USA fliegt und sich so eine Mehrweg Nummer zulegt.Aber ich habe mir die Karte nur geholt damit ich mobiles Internet habe und dies hat durchgehend super funktioniert mit 5G obwohl glaub in der Beschreibung nur LTE stand UND obwohl ich ein nicht USA iPhone Model habe ohne die Spezial 5G AntenneWenn diese Informationen hilfreich waren dann gerne auf Nützlich tippen 😁

good item, it worked for me the way I wanted it.easy to install and activate, you wouldn’t go wrong with it!the delivery was fast and as promised while purchasing

Ich habe die Karte für einen Neuntägigen Aufenthalt im Raum Chicago gekauft und dort als zweite Karte in einem iPhone verwendet.Die Aktivierung wurde ohne Probleme am gewünschten Tag durchgeführt und die Karte hat sofort nach der Ankunft sowie im gesamten Reisezeitraum gut funktioniert. Der Empfang im T-Mobile-Netz war in der Stadt ausgesprochen gut, stabil und das mobile Internet meist ausreichend schnell. Bei Ausflügen weit außerhalb von Chicago wurde es dann schon mal dünn, aber ganz offline war ich nirgendwo. Auch die Nutzung des Internetzugangs über andere Geräte via persönlichem Hotspot war ohne Einschränkungen möglich.Hier werden von vielen Nutzern zahlreiche unerwünschte Anrufe und SMS beschrieben. Mostsim weist im Rahmen der Aktivierung auch selbst darauf hin, dass es durch die Wiederverwendung der Telefonnummern von T-Mobile zu solchen Anrufen kommen kann. Offenbar hatte ich an dieser Stelle Glück, denn mein Telefon hat während des gesamten Aufenthalts kein einziges Mal unerwünscht geklingelt.Als Tipp für iPhone-Nutzer kann ich noch empfehlen, das iPhone in den USA mit der eingelegten SIM noch einmal neu zu starten. Erst danach waren bei mir die Netzbetreiberprofile korrekt geladen.

J'ai pris cette carte pour un voyage de 8 jours à New-York City. Enregistrement de la carte SIM simple et rapide, on choisit le jour d'activation donc on peut le prévoir à l'avance. Avec mon iPhone X (attention à ce que votre téléphone soit bien débloqué), aucun souci de connexion, en LTE la plupart du temps, et 4G de temps en temps. J'ai pu utiliser le partage de connexion avec 3 autres smartphones connectés simultanément. Tout fonctionnait parfaitement : whatsapp, messenger, iMessage (qui apparaissait avec un numéro américain forcément), youtube, google maps, surf sur le web, etc. Consommation de 10 Go sur les 8 jours.Les seules pertes de réseau étaient dans le métro (normal :)), donc le réseau T-Mobile était très efficace !Quelques appels publicitaires mais comme je n'avais donné mon numéro à personne, c'était facile, il suffisait de ne pas décrocher :)

A causa delle recensioni negative ero molto indeciso sull'acquisto di questa SIM perche molti utenti avevano dato 1-2 stelle giustificando il giudizio negativo con il fatto che (a detta loro) la SIM non riuscivano a navigare del tutto o se lo facevano questo accadeva con velocità lentissime. Non volendo essere polemico ma volendo essere d'aiuto a chi si dovesse trovare nelle mie stesse condizioni di indecisione dico che: molti utenti danno giudizi affrettati e fuorvianti. Il problema è che prima di acquistare un prodotto andrebbero letti i requisiti. E' chiaramente specificato il requisito: "I telefoni devono supportare 4G LTE Band 2 e Band 4". Questo significa che se il vostro smartphone non supporta le reti Band 2 e 4, non potrete navigare. Dare una stella senza essere andati a controllare che il vostro telefono supporta queste reti è fuorviante per gli altri utenti e non è corretto nei confronti di un venditore seri ed affidabile che propone un prodotto validissimo ad un prezzo interessantissimo.Detto ciò... ecco la mia recensione:Ho utilizzato la SIM a New York dal 24.07.2019 al 03.08.2019 con un iPhone 6 plus (che supporta 4G LTE Band 2 e Band 4). Navigazione velocissima in 4G, tacche sempre massime ovunque, non l'ho utilizzata per chiamare perché non ho avuto la necessità chiamando e video-chiamando in italia tramite WhatsApp (oltre che messaggiare). In ogni caso è chiaramente riportato che si possono chiamare solo i numeri americani.Ottimo prodotto e ottimo prezzo, tenendo presente che comprare una SIM usa e getta in USA costa circa il doppio, che le eventuali opzioni italiane su SIM italiane sono molto più limitative (e solo alcuni gestori italiani offrono tariffe convenienti). Io l'ho anche utilizzata come com Hot Spot per far connettere i miei figli e mia moglie (in totale eravamo connessi in 4) senza alcun problema. L'attivazione è semplicissima (baste seguire le istruzioni della confezione). Io l'ho attivata in italia prima di partire e all'arrivo era già tutto pronto.Io la consiglio vivamente a chi non vuole rinunciare ad essere sempre connesso...
