The Bangladesh Telecommunication Regulatory Commission (BTRC) has mandated that individuals with more than 10 SIM cards registered under one national ID must de-register the extra SIMs by October 30. Previously, up to 15 SIMs were allowed, but the limit has been reduced to 10 to align with international standards and enhance national security. Customers can check their registered SIMs by dialing *16001#. Around 2.6 million users will need to deactivate a total of 6.7 million SIMs as part of this new regulation.
