Controlling Roaming charges?

Hi,
Just about to go abroad with my N1 for the first time.
Any tips for controlling roaming charges (other than obviously to limit my use)? Are there any apps that can help?
Cheers.

I'm in Vancouver, Canada, and recently drove down to Seattle. Usually, when I get to the border I just turn my phone off to avoid any issues. This time though, I left it on to see what my N1 would do when switching networks. Once I connected in the US, to Tmobile, my data services automattically turned off, and I never had any additional charges.
Make sure in Settings - Wireless and Networks - Mobile Networks, Data Roaming is UNchecked, and your data services should automatically be disabled once you're roaming.

Thanks. I will be doing that.
But I will need to use it sometimes, and I'm scared that loads of background stuff will start using up data.

GPS question

Hey guys quick question would the GPS still work on the n1 if you use it with only wifi. I was thinking of getting an offline map program and then using the GPS on the already downloaded map.

I heard that google will provide an offline navigation soon. Very soon.
So you don't have to go looking for anything.

GPS can work without any data at all, WiFi or cellular. It'll just take much more time to lock on the position.
Assistance data can be downloaded on WiFi as well as cellular data.

GPS = Provides a location. Besides speeding up an initial fix over data (AGPS) to get ephemeris data it doesn't care about data. And if you don't have any data available, it will download the ephemeris data itself after a few minutes anyway over the sat link.
What YOU mean is navigation... Google Maps? Waze? Those do require data. New Google Maps 5 coming out will not in certain circumstances, and there are other offline mapping programs out there, but most rely on data to download maps, routes, and create routes.

GPS still terrible on 2.3.4 sprint tab

First of all, yes I searched the forum, and google, and tho I might have missed something, I think I've tried most of the reccommendations out there (short of a custom rom because those are in short demand for the sprint tab.)
I did a wipe / odin to 24, updated to 28, then 2.3.4. Gps still sucked, so I flashed rooted 2.3.4 and tried 3 or 4 gps "fix" apps for this thing, none of which have made any difference. I can get gps but it takes FOREVER, usually around 5 minutes. Often it will find 6 or more satellites too, but just sit there and not lock on or whatever to any, then randomly it works. I've tried every combo of toggling gps, soft reset, and hard reset.
In texas I had the same problem on froyo, now I'm in Costa Rica... I'm assuming since gps stands for GLOBAL positioning sys that where I am shouldn't affect it. But its just SO darn slow ilby the time it starts working its useless.
and I test it outside on sunny days with open sky, so I know that's not the culprit. Nor ia it in a case when I try
Any thoughts or ideas at all would be MUCH appriciated as I really need to start using my tab for mapping.
Thanks!!!

I think you're doing it wrong son. Try these settings. In wireless and network, mobile networks, uncheck 3g data. In location and security, check both use wireless networks and use GPS satellites. I assume you are using wireless tether from phone to give tab internet. Turn wifi on obviously. You do have the modded wpa_supplicant file for ad hoc for the tab right? I tried timing myself after doing all those settings I said and how long with GPS tools app and Google maps to get a lock and it was immediate. This is coming from never have using the GPS since the complete back to stock with ea24 all the way up to rooted gb.
People are saying to put the tab into airplane mode. If you want to use the GPS or things like weather bug or radar now, you at least need to have location from network enabled for it to assist in finding your location. You're not pulling data from the tower, the tower is helping the apply to locate where you're at, along with the GPS. GPS alone and wifi didn't work for me. When I enabled the settings I told you about, the GPS apps immediately came to life and worked great.

I'm in costa rica with a cdma sprint tab, so 3g is always disabled, and because there is no service I disabled network location because I figured it couldn't get that data with no signal, and my location kept going to some random location around the world. And when I need gps I'm out far away from wifi hotspots too, so not worried about that setting I don't think.
Wifi hotspots only, no tethering, and I don't have the wpa supplicant file, but again no tethering so I'm assuming that is not nessicary.
And in Airplane mode it never gets a lock. At least on froyo it never would. I would turn airplane on then activate gps and it never ever found a satellite. I researched it and I thought in airplane the gps couldn't function until airplane mode was disabled again, even if gps toggled...
I appriciate your input, but I don't think its going to work given my circumstances.
Thanks!

[Q] pls answer. tq

Hi, I Live in malaysia. Was wondering is there any GPS Navigation app in the market that doesnt requires a mobile internet or WIFI while on the road? Thanks

Sygic aura, that having malasia coverage
Others are navigon, ndrive but i dont know these having malasiya coverage

Dude or dudette..get your data plan..no meaning having such smartphone without the data plan ;P

Im Using a unlocked one. dont rely on data plans that much

ya, sygic aura wont need data plan once you install n download map.
and as per my experience Sygic is best among other i have used e.g. MapMyindia, Ndrive, Navigon

use wifi to cache over all the data in google maps and then u can use it offline

Though it requires active data connection. Try it by data off n wifi off, it will say 'data connection lost'
It just helping to reduce data consumption

Note drains faster on wifi when not roaming

Hi, when I'm abroad using wifi (so no cellular data), my battery lasts longer compared to being at home, also on Wifi. how can this be possible? shouldnt cellular data be deactivated as soon as i activate wifi?
thanks in advance

Depends on what Wi-Fi network you're connecting to. In theory - 5Ghz network takes more battery than 2.4Ghz or a/b/g network. Also, signal strength also plays it's role - constant low signal forces the antenna to work harder - and at home you always get good signal.
Who knows, maybe that's the reason.

Maybe when you are home the data connection stays in the background waiting for you to drop off wifi network and therefore eats up the battery
but when you are on roaming the data connection is turned off completely to save on data bill
this is just an assumption...
what I usually do is when am at home or work, I turn off data and turn on wifi manually instead of letting the phone choose for me. I've found that this helps in conserving battery

No, thats not how it works.. Your cellular data connection is active, just unused.

I do this too, in fact I use Llama to do it for me. It saves a lot of battery.

Thanks, that's what I thought. But why can't android simply deactivate data when connected. I don't get why there is no such option.
