Bangladesh Telecommunications Company Limited (BTCL) has started converting telephone numbers in three growth centres, including Sylhet and six upazilas.
When a subscriber transfers a telephone number within zones, it will remain unchanged. However, if transferred beyond its zone, only the first digit, in other words, the code will be changed, a BTCL press release said on Tuesday.
