We have been notified by our readers (self tested as well) that there is a server crash on Zong’s end – hence Zong users are making free calls to any number, yes international numbers too, for free…!
We have notified Zong’s administration about this. Hopefully issue will get resolved soon.
Meanwhile you can enjoy free calls… but make sure that you have no balance in your SIM to avoid balance drop, as this error will get rectified any time.
Update: Issue has been rectified, and lucky Zong Users made free calls during past 50 minutes.
