In peshawar, abbottabad, mansehra and some other KPK regions, PTCL is using different frequency than other cities.
So Wingle will not work there. And only 450MHz EVO will work there, which won't work in rest of the country.
As per my information, PTCL is in contact with other operators to overcome this limitation and may soon be able to uniform the network. But as of now, you can't use single EVO dongle.....
