Need better set up instructions
The esim worked great - once I managed to get it working. They need to make it clear in the instructions that you need to set up your account and download their app before the esim will start to work. That is not included on the instructions, and it took me 48 hours of following various troubleshooting lists online to work out the issue.
Good value for money
I’ve been using Monty eSim for several months now. They are one of the cheapest regional sim plans I could find for Europe. The customer service is very responsive and their pricing I think is fair. Their service is generally good but can be patchy in places.
Works fine for me
So far I’ve purchased two esims, one for turkey and one for the Netherlands (it connected to Vodafone). Both worked fine. Bit of a faff to activate but once it’s done it’s fine.
I found that I had to turn off my main sim whilst using the eSIM for the data to work, but maybe there’s a way around that so you can still receive calls with your main number.
I did notice that the data went down very quickly, using Google maps for a lot of the day, but still quicker than it would in the UK. And it’s fairly cheap.

Works flawlessly for global travel
Works flawlessly for global travel. No disconnections and other issues. The data consumption can also be easily tracked via their app. 3 USD for 1 GB global data is the cheapest you can get.

esim is invalid and support doesn't exist
I ordered an esim service, the esim was invalid and didn't activate. I tried contacting their "24/7" support through email and whatsapp but never got any response back. Already ordered another esim from a different company which activated immediatly.

Runs out too quick
Easy to set up but data allowance disappeared much quicker than it should.
Just used for map directions, but 1gb gone in a day!
By far the best e-sim I have used - Montye-sim
By far the best e-sim I have used. Great coverage and super easy to set up
Great customer service and very understanding
Great customer service through whatsapp. 1st esim wasnt working properly so they end up helping me to set up new esim, which work really good. Unfortunately, I left the country early due to medical reason and montyesim was very understanding and refunded the full amount right away.
Great customer support // Hotspot doesnt work
Bought an eSIM, straight forward process.
Easy to activate and such, customer support very responsive via WhatsApp, and they've helped me set up the APN configs to have data working.
On the down side, before buying i got confirmation that hotspot would work, but that's not the case. Tried two interactions with Customer Support where they were dismissive and said the issue was on my end - it wasnt as others saying they experienced the same.
What a great customer service from…
What a great customer service from these folks at Monty. I had a small issue activating the eSIM. Ayman from Cust. Serv. replied instantly to my WhatsApp then took me step by step solving the problem (which by the way was my fault). In few steps he guided me through it. Now I have a great connection for the next 30 days all over Europe. Hope Monty will post this review to others to appreciate this terrific service. Ayman is truly an asset to Monty
Worked great, no issues.
Don't know why some people complain about the eSim not working, but for me and my partner it worked great. After purchasing and setup, the activation can take several minutes, in my case about 5 minutes and for my partner approxinately 3 minutes, so just have a bit of patience.
We used it mainly in Switzerland. Always good signal and even 5G supported. Also multiple providers/networks are contracted by Monty I noticed. When we went back to the Netherlands I forgot to turn my own SIM card on, so without realising I used the eSim for several days and it worked perfectly. So don't hesitate and choose Monty!

Worked great in 3 different Countries!!!
When I first purchased it and read all the reviews i felt like "oh god, what have I done?" Instead, I have used it in UK, Germany and North Macedonia and it simply worked great, no issues at all.
After that, I have referred my friend and I have even received 3 $ cashback straightaway.

Avoid this company
Avoid this company. After my order I noticed that eSim doesn't work on my cellphone. 10 min. after my order i asked them for cancellation. They answered to check that but actually never did. Never got a refund.
