I've seen other post regarding issues with esim where it just stops working and needs to be replaced.
I'm too am having this issue, the new esim worked for about 1 week, then it's unable to connect to the network. A replacement esim resolved the issue, however after another week, it stopped again. I've ordered another replacement esim (3rd one) and I've only been a customer for about 1 month and only been able to use the service for about 2 weeks.
Is there a general issue with esims or maybe its compatibility with the Pixel?
I have had an esim in my Motorola Razr 5G for over a year, and have over 100 in the fleet of devices I manage, for over 6months and the rate of failure is about 0.01%
It is probably one to ask Google as the Pixel 6 Range is full of bugs, and in December last year Google admitted connectivity issues.
