do i need to be on T-Mobile to get oneui beta. i have an unlock s26 ultra purchase from Samsung store. I am currently on oneui 9 beta. I want to try MVNOs services. Will I qualify for maybe new oneui 9.5 or 10 in the future if I go with tello.com or mint mobile or any MVNOs. My understanding is you need to be tmobile and unlock phone. Thanks.
If you have a factory unlocked phone (which you do), mobile carrier doesn't matter. You can switch to whichever one you want.
The only instance where T-Mobile matters is if someone has a carrier-locked phone (model name ends in U). T-Mobile is typically the only US carrier that participates in Samsung betas.
