How do I locate the 3G dialup failure on an AR
Solution

"Run the display cellular interface-number network command to check the value of the Current Service Status field.
- When the value of the Current Service Status field is Service Available, the 3G service is available. Check the following configurations:
1. Check whether the dialer number is configured correctly.
2. If the 3G interface is connected to the WCDMA network or a network that is compatible with the WCDMA network, check whether the APN is configured correctly.
3. Check whether the authentication mode, user name, and password are configured correctly.
4. Check whether the dialer ACL is configured correctly.
5. Check whether static routes are configured correctly.
- When the value of the Current Service Status field is No Service, the 3G service is unavailable. Check the following configurations:
1. If the 3G interface is connected to the WCDMA network or a network that is compatible with the WCDMA network, run the display cellular interface-number network command to check values of the Mobile Country Code (MCC), Mobile Network Code (MNC), and Mobile Operator Information fields and check whether the PLMN selected by the 3G modem is consistent with that of the carrier. If the 3G interface is connected to the CDMA2000 network or a network that is compatible with the CDMA2000 network, you can skip this step.
2. Run the display cellular interface-number radio command to check the value of the Current RSSI field.
3. Check whether the 3G data card is supported by the AR.
4. Run the display cellular interface-number radio command to check the value of the SIM Status field and check whether the SIM, USIM, or UIM card status is normal.
5. Check whether the 3G hardware (including the 3G data card/3G interface card/3G model), SIM/USIM/UIM card, or 3G antenna is damaged, not properly installed, or not fastened.
6. Check whether the angle of the 3G antennas is proper.
7. Check whether 3G/2G services are enabled on the SIM, USIM, or UIM card and whether the users owe fees.
8. Run the display cellular interface-number radio command to check the value of the PIN Status field."
