The device was quick to arrive, but no browsing yet as seems to some activation glitch. I was on a long call this evening and got an MCA from Daraz rep who delivered the device, called back but no reply, will check tomorrow.
Tried contacting Zong Helpline and when I press zero for CCR, the automated message says system cannot give this service and call is cut. WTH.
The good thing is that the web interface shows strong 4G signal in my patch. I live near the checkpoint before ACE, Bahria Phase II.
