I purchased a N900 here in the US. I started using it on the AT&T network (with 2g speeds) and assisted GPS worked without any problems.
I changed to T-mobile and now A-GPS is not working. If I swap the simcard to my old N95, A-GPS does work. If I connected via wifi or GPRS, it does not work for my N900
Therefore, I beleive that my N900 is not receiving cell tower location data from Tmobile towers. It can successfully from AT&T towers, so not sure what the difference is. I don't think it's a data connection problem when contacting the location server using wifi or gprs as I can successfully perform other web functions.
Anybody have any ideas or advice on how I can resolve this problem?
Did you get a new SIM when you joined t-mo? Quite a few folks have seen issues when sim hopping (swapping sim cards between devices), these have ranged from battery drain, poor reception, not switching from 2.5 to 3G...etc.
If you have a new sim for t-mo... you need to clear out the old AT&T settings. AT&T is a pain in the butt cuz they write a ton a setting to the device as part of provisioning.
Same problem here. Tried it with a T-Mobile USA sim with 3G data enabled. Access point epc.tmobile.com.
Outdoors in clear area. GPS not connecting in Ovi maps app.
Tried an AT&t card & gps finds location in under 5 secs!
Put back t-mo card & gps worked briefly but then went out & never back again.
Assisted GPS network connection is independent of that used by OVI Maps, You must have an internet access point defined in the device to retrieve assistance data from the Nokia A-GPS service over a packet data connection. You can define the access point for A-GPS in network positioning settings. It only asks what connection to use the very first time GPS is used so if SIM changed you need to alter it manually.
Network positioning settings Select from the following: Enable — Activate the network-based positioning service (including A-GPS). Location server — Enter the location server address = "supl.nokia.com"
I had the same issue.
I went to Setting -> Location and disabled network positioning restarted the device. Enabled network positioning, restarted the device. Now it works perfect.
I did a little (okay, a lot) of googling and came across this:
Since the N900 isn't a supported device on T-Mobile (yet?) I'm not entirely sure that we'll see GPS support in the near future.
Using the N900 for navigation is a waste of time whether is it a-GPS or normal GPS. Of the 3 phones the 5800, N97 and the N900, GPS navigation on the N900 is the worst. There are fewer features on the N900, the search is slow, rendering the map is slow, A-GPS inaccurate and there are no voice instructions available. Even though I own the N900, I still use my 5800 for navigation. It is faster, easier to use, and more reliable. One of the major problems of both the N97 and N900 is speed. Most times even in city driving you are beyond the point where you are supposed to turn when you are instructed visually or verbally to turn.
same with me the GPS are very bad in coparison with E71 and E75 and even N97 ,i was used them foer the klast 2 monthes consequently but at least there is arrow in the navigation you can look at or even voice assistant while you are driving ,
sorry for that i buy it and I expect it to work more efficient in navigation while I am driving
I just tried the supl.google thing and it worked. Why doesn't it show a more accurate location, though? It places me about 5 blocks downtown.
Can anyone offer an explanation? Is there a way to increase the accuracy?

N900/T-Mobile: Do you need data plan for this? My wife's 5800 works super w/o data plan.
