Dialing on 710 ZONG!

I am trying to call to 710 from my zong number to reedem free messages plus free air time but "Network Busy" error is coming again and again.Can you even call on this number ?

It mostly gives Network Busy error, "Mostly" not "Always".

Send a blank SMS to 710 instead. Works well for me.

always works for me

sometimes it shows networking busy...........
