My iPhone XS 256 GB Gold has no carrier service. It’s new

I bought my cellphone in dubai, I was in India used 2 different local carriers and they work well. I came to South Africa and tested VodaCom, has no service.

already call my network carrier and the iPhone is not blocked by the carrier.

already did all the steps of the apple support.

tried to look after a carrier settings update, turned it off, remove and put the SIM card again, restart the fine, reseted the iPhone, everything...
