SIM verification
To see every Zong connection on your CNIC, use PTA's 668 service. If you find a SIM you didn't buy, visit an official Zong franchise or service centre with your original CNIC and ask for it to be blocked. Biometric (fingerprint) verification is required for new SIMs, ownership changes and duplicates — do it only at an official outlet.
Internet packages
Zong changes bundle prices and volumes often, so we don't list them here. For current daily, weekly and monthly offers, use the My Zong app or the official website. Before subscribing, check the validity period, fair-usage limits and whether social or video data is counted separately.
Balance checking
Dial *222# for your main balance. Bundle resources (MBs, minutes, SMS) are shown in the My Zong app. A small service charge may apply to some balance enquiries.
SIM replacement (lost, stolen or damaged)
- Call 310 or visit an outlet immediately to block the lost SIM.
- Visit an official Zong service centre or franchise with your original, valid CNIC.
- Complete biometric verification — the SIM must be registered in your name.
- Pay the replacement fee (if any) and receive a new SIM with the same number.
- Update OTP-linked accounts (banking, wallets) once the new SIM is active.
Zong 4G and data tips
Make sure your phone supports the 4G bands used in your area and that "4G/LTE preferred" is enabled in mobile network settings. If data is slow, check remaining MBs in the My Zong app before contacting support.
