To see if you have access to the data network, you should try to access a website using your mobile
browser. You may also switch on Wi-Fi if a Wi-Fi network is in range.
If you want to reconnect only to the cellular data network, then turn off Wi-Fi in the settings. See the
Menu on page 35 settings section for more information.

User Busy
When you make a one-to-one PTT call to another person and they are engaged in another PTT call or
a regular cellular call, you see a message indicating that the person is busy. If you receive this
message, you can try your call later or send an alert. See the
Sending an Alert on page 76 section for
details.

User Unreachable
In rare cases, a contact might be shown as Available in your contact list, but might be temporarily
outside the range of service coverage. In this case, your PTT call cannot go through. The called
person’s status updates to Offline until they reconnect to PTT service. If this happens, you should
wait for their status to be shown as Available and try your call again.

Login Failures
Login to the PTT service may fail if the phone is in Airplane Mode or if you do not have a data
connection. Please check the data connection and try to log in again later.
22.16
Presence Status Does Not Update
If you attempt to change your presence status from “Available” to “Do Not Disturb” or vice versa, and
you do not see your status updated, there may be a communication problem between your phone and
the PTT server. Logging out and logging in again should solve the problem. To log out, see the
Logout on page 155 section.

Quick Group Calls I Receive Are Shown in History as a One-to-
One Call
When you receive a Quick Group call, you notice that the call history shows a call received from the
originator of the call, which is normal. You cannot call a Quick Group that was created by someone
else. Any Quick Group calls that you make show in the call history with the names of the participants.
You can call that group again from your history. For more details on Quick Groups, please refer to the
Making Quick Group Calls on page 57 section.

Wi-Fi Connection Problems
Using the PTT application over Wi-Fi requires that the phone can access the Internet through the Wi-Fi
connection. While your phone is connected to Wi-Fi if the PTT application gives you the message
Data connection is unavailable, ensure that the Wi-Fi service provider does not require a
username and password and that the Wi-Fi application setting is enabled.
