Downloading updates using different carrier simcard

[Tre1300]

Hey guys,

I'm using MTN ZA as my carrier here in South Africa. They are very slow with system updates as Vodacom ZA are 2 updates ahead of MTN ZA. 

So I would like to know if I had inserted a Vodacom SIM card, will my XZ1 get the updates Vodacom ZA released and MTN had not?

Thanks guys!!!

Hi @Tre1300;

The updates are Costumization Version dependents (device's firmware), it will not make any diference replacing the SIM card.

Thanks for the reply.

My best bet is to flash using experifirm and the Xperia flash tool.

If I was to flash another region firmware. Would I get the updates according to that region as they release the firmware.
