agreed, using warid for around 10 years, never had any issue regarding voice quality, connectivity, internet, coverage and helpline. Tried Zong once and its helpline service was pathetic, too much wait.. before warid was using jazz mobilink, and that time mobilink was called 'may-be-link',, very difficult connectivity most of the times..
but now i think ill have to switch if warid doesnt come up with something solid before other companies announce their 3G packages..
