eSIM is great 👍

I’m useless and Carl from eSim helped me to set it up step by step and works beautifully. Was very easy to understand the steps and bang worked immediately. Very please customer. Also the eSim works very well in UK - I came here regularly and makes my life so much easier. Thank you

Try it and see...mine worked out great.

I saw an advert in the Times to try this eSim when I was going to Georgia. It is not a country that my current mobile network provider (EE) offer a reasonable package.

The installation was simple and I got message that it will work when I arrive. And it did!

The speed of download was good and eSIM-On has partnered with some good providers that offered reliable 4G pretty much throughout our trip in Tbilisi. One of the speed tests showed 199Mbps download 4Mbps upload.

When I had to ask for support via WhatsApp, they were very responsive. I was concerned that even though it said I had installed the eSIM, you are not going to know if it is going to work until you land.

It was a good price for the 4 days we were there. The 1Gb offer was reasonable. I didn't think I was a big data user, but perhaps if they had a few more variety of packages rather than jump 1Gb to the next band, that would be better.

All in all, v happy. Will use them again when I go on the next trip.

This apps is very useful and helpful. Easy to use and install and top up the balance. And I could use it again later in future by toping up the balance. The support whenever you have an issues or problem also quick response and helpful. Thanks

Stunning customer service

I had trouble starting the process installing the esim. I had an immediate response to my email and was put through to Carl. Using WhatsApp and screenshot he had me up and running very quickly. I have no problem awarding 5 stars.

I had a great experience with Nems…

I had a great experience with Nems while setting up my eSIM. They guided me through the process step by step, and everything was activated quickly and smoothly. The service was not only efficient and hassle-free but also affordable. Highly recommend their service and support while traveling anywhere around the world.

Not sharks, good guys!

The big telecom companies are sharks feeding off people who don’t know about, or daren’t try eSIM/eSIMs. If we had used EE we would have paid, in a day, what eSIM deliver for 15 days. Even more impressive, when I stuffed up the install they walked me through it, instantly, online, making everything quick and easy to get up and running properly. Compare that with EE ‘support’ ….takes hours to respond, gives you duff info, etc., etc., etc.

PS: Big shout out to tech support wizard Nems, great technical info communicated extremely well.

Great customer service!

Great customer service!! I am not very tech savvy and had some difficulty knowing which SIM on my phone was my actual eSIM. I immediately got support through WhatsApp, where I was very patiently walked through the entire process of getting everything set up. So appreciate the help Nems gave me!
