G1 Data Always Connected = Roaming $$$

Sounds like a Google thing. Very scary stuff.

THANKS LRRR IT WORKED =DD

My understanding of the problem is that even with Data Roaming disabled, sometimes your G1 thinks it is on its home network when it is actually roaming. Let's assume you are a T-Mobile USA user. The problem occurs when your are on, say, the UK T-Mobile network. The G1 thinks it is your home network (because they are both T-Mo) and thus disabling Data Roaming has no effect.

There does seem to be a solution: Disable all data connections on your G1:

1. Use Anycut to create a shortcut to "Testing"
2. Click on Testing.
3. Click on Phone Information
4. Hit Menu button
5. Click on More
6. Click on Disable data connection

This turns off all data access. Note that GPRS service switches to "disconnected". Now you should have a phone that does voice calls, but no data access.

Follow-up: After disabling the data connection, you can, of course, use your wifi without incurring data charges. However, when you turn off your wifi, your G1 will automatically re-enable the data connection. So, after you use wifi, don't forget to re-disable your data connection.

I always get the message "com.android.phone crashed" when I click the testing link -> Phone information, but only if there is an active EDGE/GRPS connection. After that the sim is locked again and I have to input the PIN again... no way for me to turn off that stupid data connection? :( can't believe it crashes for me and nobody else.

Thanks. Works and vastly improves battery life!

Thanks a lot, It was driving me crazy. But, why is the G1 always maintaining an open connection, either in your own network?

LRRR, this is what I want:

"After disabling the data connection, you can, of course, use your wifi without incurring data charges."

I just want to be able to use my phone for email over wifi. No phone calls, no IMs, no apps. Can you review what exactly I do to make this possible without roaming charges? How do I get to "testing" without Anycut?

memphisto, I have the same problem as you, have you figured it out yet?

what is anycut??, im trying to use the g1 with at&t but i do not want the data charges too, plz specify how to disable the data sync, because i do not know what is anycut is

THANKS. I have lost all the credit on my sim. Huge help.

The best solution I have found is to remove the APN's, if you don't want Data connections. With no APN defined, it won't make a GPRS connection and saves you the connection costs. Only works if you don't use the GPRS for connections, just the WiFi

Just got a 1,048 data roaming charge. Had NO idea I was supposed to turn off data! On the phone now...

If I disable data connection, that means no 3G right? hence signal and speed goes down?
