What should I do if my Tenda MiFi cannot detect SIM card?

Here we take MF3 as an example:

If the System Information shows “No SIM Card ” such as the screenshot below, please try the troubleshooting steps in this article.

Step 1: Reinsert the SIM card, make sure it is inserted correctly and try to press the SIM card slot to make sure there is good contact between the slot and the SIM card

You need to choose the corresponding model of SIM card, MF3/MF6 usually use the following Nano SIM card

Step 2: Restart the 4G router while the SIM card still inserted into the device

Remember to check the SIM card status again on the System Information

Step 3: Test the SIM card on another 4G device or smartphone to make sure the SIM card itself is working fine.

Step 4: Try to insert a different SIM card if you have

Step 5: Try to factory reset the device by holding the reset hole for about 10s until the mobile Wi-Fi device reboots automatically

If the problem still exists after the above troubleshooting, please contact Tenda Support
