Question about using with T-Mobile

"I'm planning to transfer my eSIM from my iPhone 14 to a Google Pixel 9a. Has anyone run into issues using GrapheneOS with T-Mobile?"

GLinux you realize T-Mobile is a global Telco operator right?

yes I do

I have a physical T-Mobile sim and have no issues with running GOS.

I wanted to check I new to this type of OS and wanted to make sure that before I had my number transfered

I switched from AT&T to T-Mobile about 2 months ago with Graphene with no issues.

FYI: This question has been discussed numerous times on here. A search of the forum will provide those threads.
