I just got my Zpad t6 and the 3G works fine. Just had to add in my network APN settings.
The query I have is if I can enable my Zpad to make calls. I got it to send SMS by using GO SMS and I have 3g coverage for the net but I'd like to a add in the feature to make calls but zpad seem to have restricted this.
I downloaded Go Contacts which had the dialer as well but when I dial out it comes up call ended straight away.
