PTA’s SIM Registration Limit
According to regulations, a maximum of 5 SIMs can be registered against a single CNIC, across all cellular networks combined (Jazz, Zong, Ufone, Telenor). If you already have 5 SIMs registered and want to activate a new one, you’ll first need to block or disown an existing SIM.
This limit was introduced in the early 2000s after telecom growth led to a sharp rise in easily obtainable SIM cards, which were sometimes used for fraud and illegal activity. In 2009, the SIM Information System was launched, giving every citizen a way to verify the SIMs registered under their own CNIC.
