In Bangladesh, phone numbers starting with the prefix 017 are originally assigned to Grameenphone. Grameenphone is one of the largest mobile network operators in the country.
However, due to the Mobile Number Portability (MNP) service, users can retain their phone numbers while switching to a different operator.
This means a 017 number could potentially be used on networks like Robi, Banglalink, or Teletalk if the user has ported their number.
