Followed instructions to make "cumulative 5 minute call" with middle east/north africa sim: regional unlock.
1st issue: wifi calling available?
Searched settings for wifi calling. Initially something pops up, such as an option but it asked for ?phone number? I dont recall, was too excited about getting ready to pop in sprint sim from edge6.
During this search i was waiting for smart switch to execute bringing files from edge6.
When its all done i see nothing about wifi calling on 955FD.
2nd issue: activating 955FD to Sprint network.
Called Sprint, they asked for HEX gave them the IMEI number, then informed phone is not compatible.
They informed me i could go into sprint store and have them flash the device to place it on sprint's system. But that didnt sound confident. The phone is not compatible but can be flashed.
I was told once before by sprint international they have special sims to be used on foreign devices. But after failed activation informed me the international sim would not work either. I am never satisfied with first tier help/information from sprint.
I am open any advice. Last hope is to switch to TMobile which i read in another xda forum it will work. But i am concerned about the wifi calling mainly.
