very convenient app to buy an eSim for travelling, you can choose the countries you need and have it in one pack, you can filter the options by the GB space and sort it by price, so it takes less time then just manually comparing different eSim apps. Local 5G internet works well

It's the most easiest simplest way of taking data with you. A quick flick of the sim button and that's it. Highly recommended.

Purchased eSIM in Australia and set it up in Azerbaijan. Having never used an eSIM before, I had a few ‘user issues’. These were sorted out very quickly via email and me sending a screen shot of my ‘attempted’ setup. Technician got back to me in very short order with some simple instructions and now all good. Great efficient service.
