I tried to reach my voice mail, but dialing 123 didn’t work. What should I do?
Dialing 123 to reach voice mail will only work if you are in your local T-Mobile network. You can use the Speed
Dial shortcut key 1 to reach your voice mail when you are out-of-area.
Where is the antenna located? I’d like to make sure I’m not covering it while on a call.
If you’re looking at the back of the device, the antenna is dead center. The best way to hold your device is
illustrated below, with your fingers holding the edges and your palm not covering the back of the device.
The listening sound is best when you hold the phone tight against your ear and the “mouthpiece” slightly away
from your face, as shown in the illustration above. The microphone is sensitive enough to pick up your voice
even if you hold it at this angle (about 20-30 degrees relative to your face).
Can I search for a person quickly in the Look Up screen? I don’t want to scroll.
Just start typing part of the person’s name and the Match pane will open automatically, narrowing your search.
I tried to make a phone call, but the screen read NO GSM SERVICE. What does this mean?
It means your device is not connected to the network that delivers voice service (the GSM service). Your device
will connect automatically, as soon as it can pick up a signal. Read more in the answer to
When I’m on the
phone, the “G” in the title bar disappears. When I hang up it comes back. Why?
on page 223.
Can I disable outgoing caller ID when placing a phone call from my device?
Yes, you can disable outgoing caller ID by typing #31# before typing a phone number in the Phone application.
Your caller ID info will not be passed to the person you're calling (it’s just like using *67 on the American PSTN).
