What is the T-Mobile extended Network? I switched to an unlocked S10e and boost site made me upgrade my phone plan. now i cant switch back to my LG G6 because after I enter my IMEI it says "Unable to use this device. You must swap to a device that is compatible on the T-Mobile Extended Network."
So I understand that I am using the Tmobile network now and that does not use the Sprint network.
1. Will Tmobile utilize the Sprint network? How long will that take to combine them?
2. Is my phone able to use both networks?
