Another layer of protection using a dedicated text message is being worked out by telcos to protect mobile phone users from financially devastating number porting fraud which could cost up to $30,000, Stuff reports. Starting Thursday, mobile phone users who switch providers and want to keep their phone number – a process called number porting – will receive a dedicated text message to help prevent fraud. The dedicated text message is part of a series of protective measures from the mobile phone industry, and a more advanced solution is expected to be launched in October.
