Q: What shall be noted if 3G wireless module is used for dial up?
A: If built-in wireless module WCDMA or EVDO is selected, the
module settings are different and also depend on the model used;
thus, please check the consistency between the module used and SIM
card. Do not use Telecom Card in WCDMA-enabled devices.
2. Check if the server IP or port is correctly set, if 3G/4G signal
is intense enough for dial up, and if dial up via 3G/4G is
successful.
3. Please check if the 3G/4G antenna is properly contacted when
dial up fails. Weak signal may result in failure to dial up; in
addition, check if the SIM card has sufficient traffic; if not,
dial up will also fail.
Q: What shall we do when no video is reported via 3G/4G?
A: press the "INFO" key to enter the System Information page, where
you can check if the SIM card is present, inspect signal intensity
and dial-up status, and check if the antenna is properly contacted.
Then, check if the SIM card has traffic and replace it will a new
one to re-check it. This
is a most basic judgment criteria. If a signal is available, while
dial up fails, check if the center number and port are set
correctly. Then, check if the device number is unique.
