Hi new family. I have US Mobile (up until today with an iPhone 13 PM, but it's battery went dead after a good 5 years.) I haven't been on Android in decades, but I vaguely remember custom ROMing some phone on Sprint. I work in IT Mngmt so I get it.
Anyways, I became very enamored with the privacy community so I looked on US Mobile and behold, a Pixel 10 for about half the price you'll see at most places (including Amazon). Just got it yesterday, and I'm about to eSIM activate it and try flashing GrapheneOS through this morning/afternoon.
Edit: The new Android 17 Graphene too. Phone came with Android 16, it had the option to upgrade to 17, which I'm about to do unless anyone wants to stop me in the next 5 minutes.
I did speak to their support briefly and (subtly) about it and they essentially said as long as payments are being made, your "carrier" lock won't get extended past the 60. I've got a strong feeling the bootloader will be good to go here in a moment when I start.
Anyways, regardless, they did confirm the "carrier" lock for 60 days as long as you have kept up with any bill or invoice you have with US Mobile during that tenure, otherwise they extend the "carrier" lockout for an entire year.
Plus they give us QR codes to authenticate eSIMs ourselves, which Perplexity tells me is like the cream of the crop, no Google authentication or verification or servers whatsoever.
