Sorry,
it is in the SIM, which is programmed at the time of manufacturing the SIM.
Vodaphone acquires Hutch in India. But the older SIM still displays the TEXT in the select neighbours option of handset as Hutch, whereas the new SIM’s which are coming ti the market after the takeover took place, displays the same NCC/MCC/MNC or whatever key is the input is generating the output as Vodaphone instead of hutch.
