Well, I guess that rules out the Pixel 8 as my next phone. My telecom, as with most in my country, only issues eSIMs to phones that they officially support - in other words, Samsung Galaxy phones and iPhones only.
Unless they have some fancy/magical way to install the esim remotely on your phone (which I highly doubt), they will just send you an email with a QR code to scan. And guess what, the Pixel can totally handle that.
