WAAS only works in North America. I don't know details elsewhere, but the
PMTK313 message says it turns searching for SBAS satellites on and off.

==================================

Thanks for the information on the messages, Jim.

For your information, in Europe we have EGNOS, which works in the same was 
as WAASfrom a different set of geostationary satellites.

I have not WAAS/EGNOS tested on the MT3339 chipset, but it does work on my 
Garmin GPS 60 CSx.  I don't know whether the iPad uses WAAS/EGNOS, or my 
Moto-G phone, but the latter can see GLONASS as well as GPS, which I didn't 
know until I checked it after the recent GLONASS outage.

Cheers,
David
