Troubleshooting

1. Why am I unable to connect to a mobile service network?
The DWM-156 requires a SIM card registered with a compatible service network. For information about the services
that your SIM card provides access to, please contact your mobile service provider. The adapter will not connect to a
service network unless all relevant settings have been specified correctly. Please make sure that all connection profile
settings are accurate.
2.Why is the software asking for a PIN number?
For security, some SIM cards have a PIN number enabled. If the SIM was used in a previous device, the PIN will be
the same as it was before. If you did not set a PIN, please contact your mobile service provider.
3. Why are the connection speed and data transfer rates slow?
Please check the network signal strength. A low signal will result in poor performance.
4. Why am I unable to receive SMS messages?
This may happen with the SIM card memory is full. You may need to delete some messages to free up space.
5. Why is only part of the name saved when adding a new contact?
The SIM card can hold a maximum of 12 letters/characters for a contact name.
6. Why does the Windows connection icon display a speed of 115.2 Kbps?
115.2 Kbps is the data rate of the USB device, not the connection speed. Please refer to the connection statistics
shown within the Mobile Connection Manager for the actual connection speed.
