       1. Network conditions:
       The frequency band of the live network does not match.
       The signal is not stable.
       The signal is weak.
       Network saturation
       2. Parameter configurations such as APN, user name, password, and authentication type are incorrect.
       3. SIM card issues:
       The SIM card is out of service.
       The SIM card is bound to a device.
       The SIM card is locked.
       The SIM card is damaged.
       The SIM card is not in good contact with the connector.
       4. The firmware of your device does not have a complete abnormality processing mechanism that can determine the dialup conditions or have proper timer requirements.
       5. The device is configured incorrectly.

Q3: What factors will cause the disconnection of N720 TCP client?
       Network saturation, network mode switch, network latency, unstable signal, incorrect SIM card configurations, incorrect logic of server software, incorrect logic of MCU software, etc.

Q4: The N720 module cannot connect to the server. What might cause this issue?
       1. The SIM card is out of service of the data quota is used up.
       2. The network signal is weak or there is no signal.
       3. The IP address is released after the module obtain it. For example, the base station releases the IP address after the module restarts.
       4. The APN or username and password are incorrect so that the obtained IP address is not in the same network segment with the server.
       5. The firewall on the server is not set correctly.
       6. Though you enable the roaming service, the data services of two private networks are not reachable to each other.

       1. The SIM card does not have good contact with the card holder.
       2. There is dirt on the SIM card holder.
       3. Some component is damaged in the SIM network or some pin is not soldered properly or short circuit.

       1. Logs of UART AT
       2. Logs printed by device
       3. Modem logs, server logs

N21
Q1: Does N21 support the Bluetooth function?
       Yes. it supports BT4.2 for data transmission.

Q2: Which kind of package does N21 adopt?
       The N21 module adopts 22-pin LGA package. After it is mounted onto a PCB board, all its pins are hidden. This package enhances the product safety by reducing the risk of oxidation and short circuit.

Q3: Does N21 support remote wakeup from the PSM mode?
       No, it does not support remote wakeup by commands. In PSM mode, N21 wakes up automatically after TAU times out or can be wakened locally.

       Yes. N21 supports 3GPP Release 14 and is also compatible with Release 13 and earlier versions

Q6: Do I need to set APN for the network registration of N21?
       APN is optional for the network registration of N21.
       If you set an APN, ensure that you set it correctly. The APN you set must match the SIM card you use. Otherwise, the module might fail to attach a network.

Q7: How long does it take the N21 module to attach a network in an environment with good signal coverage after the module is started?
       It depends on your network. Please consult your carrier.
       It is recommended to extend the waiting time for the module to access a network since the network conditions might change in the future.

Q8: Which kind of startup does N21 support?
       N21 supports automatic startup triggered by powerup and startup controlled by MCU.
       The 5th pin PWRKEY_N of N21 is used to control the startup function and it is connected to the 1.1V power domain through a pullup resistor.
       If you connect the PWRKEY_N pin to the ground through a 1.5kΩ resistor, the module automatically starts up after power is supplied.
       If you adopts the schematics of button or MCU control for PWRKEY_N, the module starts up after the pin is pulled low for 2 seconds.
