Why can i not download the eSIM on my iPhone 11?

Hi,

I’ve moved to the Netherlands and I wanted to acquire an eSIM for my usage. I’ve decided to get a prepaid eSIM from Simyo as my friend’ suggestion. I’ve opened my account and from the website I’ve confirmed my phone(iPhone 11) is eligible for eSIM usage. My login details came with email and I’ve downloaded Mijn Simyo app from App Store. But, when I tried to logging in, the app says that my phone is not support eSIM service as you can see from the screenshot below.

I’ve searched the internet about it, I’ve checked that my phone is sim unlocked and it’s unlocked. I’ve also changed my store country to the Netherlands as well, it didn’t work. I’ve tried to remove my physical sim and it didn’t work either. Rebooting phone, reinstalling app didn’t work either.

Please help me with this problem because I’ve just moved here and I cannot use my physical sim and I don’t have time for getting a new physical sim either.

I’m looking for your replies, thanks in advance.
 

Have a nice day.
