The esim worked well for me in Qatar. I was connected to the internet from when the airplane landed at the airport.
They have the most affordable prices for all their tiers (1/3/5/10/15 GB) on esimdb.
The team is friendly and I recommend them.
You just have to scan the QR code before flying and don't forget to enable data roaming.
The esim did not even install, and when I tried asking for a refund the provider did not agree. Worst esim provider. I do not recommend.
It was not a device issue as I have used multiple esims on the same device before.
