Citycell uses the following numbering scheme for its subscribers: +88 011 XXXX XXXX
Where, 880 is the ISD code for Bangladesh and is needed only in case of dialing from outside Bangladesh.
11 is the prefix for Citycell as allocated by the government of Bangladesh. Omitting +880 will require to use 0 in place of it instead to represent local call, hence 011 is the general prefix.
An example phone number of Citycell (when calling from inside Bangladesh) would be 01190000001.
