P1’s WiGGY is not a mobile broadband service, yet. Until P1 expand its coverage, especially in building coverage, we can only say that WiGGY is something portable that offers you a wireless connection, similar to WiFi.
I strongly recommend that you consider Maxis, Celcom, DiGi or U Mobile for a mobile broadband service.
If you notice, P1 does not brand it as a mobile broadband service, they call it personal broadband service.
