to the router. The router will turn on automatically and search for

available mobile networks.

network.

this may damage the SIM card.

5FAQs

How do I restore factory settings?

When the router is turned on, press the reset button for approximately

3 seconds using a pointed object until the indicator starts to blink.

Restoring factory settings will restore the settings to the default. You

can reconfigure them after the router is restored.

What should I do if I forgot the Wi-Fi password or the login

password for the web-based management page?

Restore the router to its factory settings and then use the default Wi-Fi

password and login password to try again.

What should I do if the indicator is red or an Internet

connection cannot be established?

1. Check if the SIM card is inserted. Refer to the Getting started section

for the right size of SIM card and the right way to insert it into the slot.

2. If the issue persists, restore the router to factory settings and try

again.

3. Contact your carrier to check if your SIM card is out of service. If it's

a new card, check if it has been activated.

What should I do if the Internet speed is slow?

1. Check the signal indicator on the router. If it shows weak

signal, adjust the router’s direction or move it close to a window to

improve signal reception.

2. If your device is connected to the router over Wi-Fi, adjust your

device’s position to receive better signal.

3. Restart the router and your device, and try again.

4. Check if you have reached your data traffic limit for the month. If so,

your carrier may limit your Internet speed.
