Review: 4G / LTE worked well in Montreal - This worked well in Montreal. There were usually lots of networks / providers to choose from and I left it on automatic network selection. Occasionally there was no data, that was always when connected to Videotron, so I would have to switch manually to one of the others. LTE speed was always pretty good for general use (didn't run a speed test; used IPlayer radio, skype voice calls). On the last day at the airport I tried downloading some Netflix to use up the remaining allowance but it seemed to throttle it somehow (other stuff still worked; the Airport wifi also blocked / limited / throttled Netflix). Easy enough to do the registration step before leaving (but try to do it in advance because it takes a day or two). I used it in the other sim slot in my Android phone and that worked fine; I just enabled the sim slot on landing. Maybe took a few minutes for the data to start working but then fine all week. I had intended to look around for cheaper alternatives locally in Montreal but I bought 5Gb allowance and used less than 1Gb in 8 days so I never bothered. Did get some spam calls but never answered them as I didn't give out the number. Didn't even try calling home with it (tells you not to); I just used Skype to Phone which was fine over LTE if a bit laggy. Probably a bit expensive (~Β£30 for 10 days 5Gb data in Canada) compared to buying something locally but worth it for the convenience of having it right from landing. Not aware of receiving any further spam from Mostsim so far (2 weeks after buying). Review: That the product did exactly what it said it would do! - Did exactly what it said on the tin! I travelled 1300 miles in 4 days - Boston, Niagara Falls, Toronto, Montreal, Vermont, New Hampshire, Boston and this sim worked perfectly! It never let me down once! Never had to change networks or anything between the US and Canada. Just popped it in the phone after I arrived (had already verifed that it worked back in the UK - make sure you do that) and was able to order my Uber instantly! The only time I wasn't able to get a signal was in the mountains in New Hampshire. Well I don't think that was down to the sim! So if you need it for Google Maps, Sending untold pictures of everything back to the UK, calls on Skype or WhatsApp, then I can only praise this! For just over Β£20 for 10 days - Was in the States for 8 days so bought the 10 day Sim just to cover two Saturdays. I very rarely have the time to leave feedback on items purchased, but this item definitely warranted it. I'm in Florida in November for 7-10 days! Will be back with a comment on coverage down there. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07F77S8J7 | | Customer Reviews | 4.2 4.2 out of 5 stars (81) | | Date First Available | 14 Mar. 2018 | | Item Weight | 20 g | | Manufacturer reference | IT EZ LRL Watch 0208 521 | | Other display features | Wireless | | Package Dimensions | 14.4 x 11 x 0.4 cm; 20 g | ## Product Details - **Brand:** MOSTSIM - **Cellular technology:** LTE - **Service provider:** T Mobile - **UPC:** 602798996727 ## Images ![MOST SIM - T-Mobile SIM Card for USA, Canada and Mexico, High Speed Data and Unlimited Calls/Texts - 10 Days - Image 1](https://m.media-amazon.com/images/I/51gC7Kojv6L.jpg) ![MOST SIM - T-Mobile SIM Card for USA, Canada and Mexico, High Speed Data and Unlimited Calls/Texts - 10 Days - Image 2](https://m.media-amazon.com/images/I/51pdCX1NWvL.jpg) ![MOST SIM - T-Mobile SIM Card for USA, Canada and Mexico, High Speed Data and Unlimited Calls/Texts - 10 Days - Image 3](https://m.media-amazon.com/images/I/61Zcalwr5yL.jpg) ![MOST SIM - T-Mobile SIM Card for USA, Canada and Mexico, High Speed Data and Unlimited Calls/Texts - 10 Days - Image 4](https://m.media-amazon.com/images/I/71RNO49RssL.jpg) ## Questions & Answers **Q: Does the sim work with Samung s8, s9 and iphone8?** A: Works with s7 edge **Q: I have completed the form online two days ago, but I haven’t received the email notifying number, or do I get the number on the activation day?** A: Yes **Q: Does this work in a Samsung galaxy 7edge** A: yes it will **Q: Can it be activated in UK?** A: Yes, you can appoint the activation date when you're in the UK.

It was used in a spare phone and the phone used as a Wifi hotspot. The SIM was easy to set up, you go online to register and set your activation date. it was activated on time and worked perfectly. Not the SIMs fault but remember it is like having a Mexican phone, calls to UK phones are overseas calls which aren't covered in the plan. Calls and texts to Mexican (or other North American) numbers are fine. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/75179088-most-sim-t-mobile-sim-card-for-usa-canada-mexico](https://www.desertcart.vn/products/75179088-most-sim-t-mobile-sim-card-for-usa-canada-mexico) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-24*
