Important accuracy note
Bangladesh mobile prefixes identify the original mobile operator, not a city or district. A number used in Chattogram can have any valid Bangladesh mobile prefix.
For location-sensitive cases, treat caller location as unknown unless the caller voluntarily provides it or it comes from a trusted business directory. Do not assume a person's district from a mobile number.
