i see, cos some devices support A-GPS but not standalone GPS
so when there is no network coverage, then no more GPS
i think you don't fully understand what A-GPS means. so when there is no network coverage, then no more GPS
if you read from the wiki i posted the link earlier, you should be able to understand what is A-GPS is all about.
basically the A in front of GPS is an added service to "standalone" GPS. if you turn on the "A" then your GPS will lock your location faster than when you turn it off. if you chose to turn the "A" off, it may slow down the locking process from the cold start but you'll still be able to use your GPS.
the only difference is the initial start of GPS, locking process is with or without assistance.
or in other words:
A-GPS : a standalone GPS with added service during the locking process.
standalone GPS normally doesn't come with GSM receiver/internet connectivity to make use of "assisted" locking process.
A-GPS will work with or without network coverage since it is using satellites to get your location once the location is locked.
it may lock your location slower if there's no network coverage or if you choose not to use it for some reasons.
