Question

Hi,

Recently I faced a popular problem with the Sim Card NO INSERTED status on RUT240 router.
Changing the settings and firmware upgrade didn't work so I started to analyze a hardware side to find a problem there.

I've checked connection between Quectel EC25 chip and card sim holder I it's turned out that RST pin leg was not well soldered and hangs in the air. (pic attached)

Correcting the connection helped and router is working correctly.

It is probably a production defect, considering how many people have the same problem.

 

Hope this will be helpful!
