Help me, how to active 4g signal with BlackBerry z10 in indonesia
Check your model Z10. you posted STL100-3, against this chart to see what LTE (4G) brands and frequencies your device supports: http://forums.crackberry.com/blackbe...encies-775253/
Then check your cell carrier to see what bands and frequencies they transmit on.
If your Z10 doesn't match your carrier's bands/frequencies, then you wont get 4G (LTE)
