T-Mobile locked iPhone 5s, 6 and 6 plus
 

hi,

x-sim evo ultra works on iphone 5s, 6 and 6 plus locked on T-Mobile as long as the firmware is 8.2 or below...

if the firmware is 8.3 or higher, phone will be "ACTIVATION REQUIRED"...

i tested a working x-sim in a 8.2 iphone 6 plus and it's working as it should but the same x-sim cannot work on a 8.3 iphone 6...

hope the coder can do something about this...
