lastest Firmware update question

[TonyV5]

When a firmware update is sent to the mobile that has the WiFi enabled will use it, OR is it sent as mobile data at the users expense?

Welcome to the forum @TonyV5
The OTA (FOTA) update will be downloaded over WiFi for as long you have the WiFi connection. But if by some reason you lose the WiFi connection, than the update will still be downloaded through your mobile data allowance...

Thank you Smokey,
Data & roaming are never set, the first JB BTU i8160XXMF1 update lost the APN settings & depleted my credit, this one this week BTU i8160XXMK2 the APN ok but again now low on credit.
