I think Zong really giving interesting packages (not the flood of packages like Ufone). The main reason why I like Zong more than Ufone is that any package Zong offers has truly "Unlimited" minutes (except for Flutter package) not like Ufone shouting UNLIMITED, UNLIMITED but giving only 100 minutes.
The only thing I really dislike about Zong is the limited number of SMS allowed. For weekly package 1,000 SMS are allowed, they are OK but I think at the time of re-subscription the remaining SMS should be added to the package just like Ufone offers.
Secondly for monthly SMS package, instead of giving 500 SMS/day they should offer 1,000 SMS.
What are your likes and dislikes about both companies?
