Call Block Service enables subscribers to easily block unwanted calls to their mobile phones anytime, anywhere through its Blacklist feature. Recently, Grameenphone has also introduced the Whitelist feature to allow only certain numbers to be able to call the subscriber, keeping all other callers blocked.
Any GP subscriber can subscribe to the Call Block service.
SMS: Type Start CB and send to 5678
USSD: Dial *111*1*1#
IVR: Dial 5678
SMS: Type Stop CB and send to 5678
USSD: Dial *111*1*4#
IVR: Dial 5678
To make it easy for the subscribers, GP has introduced a fully functional USSD menu for this service, which will guide the subscriber through all the features of this service. This can be done by dialing *111# and follow the instructions.
A GP subscriber can block/allow as many numbers as s/he wants starting with first 10 free slots. For example, a subscriber blocked 10 numbers by using first 10 slots. After a period, s/he can delete one number from the slot and add another number with no additional charge. In this way, the subscriber can remove any number from the first 10 slot to add new numbers in the Blacklist/Whitelist. After free first 10 number slots, subscribers have to pay for each number he wants to block/allow from 11th to 20th slots.
For your convenience, Grameenphone Ltd. has introduced “Weekly charging” feature for Call Block service, applicable for eligible prepaid subscribers only.
