SLK-E940 upgrade method

Dear customers

We are truly sorry that the US version of SLK-E940 may not be able to connect 4G network.

The reason is that to be compatible with 4G modules from different carriers, the AT command of the dialer is incorrect.

Customers who have bought SLK-E940-US must upgrade the latest firmware we offer.

(Upgrade configuration file would be invaid if you reset the router.)

Once again, we apologize for any inconvenience caused.

Yours sincerely

Shenzhen Shifang Communication Technology Co., Ltd.
