How to set up Dual SIM

1.    Connect PC to router and log into the router. Go to Network => Cellular.

2.     Check “show advanced Options” and “Dual SIM enable”.

3.  Scroll to the bottom, and create 2 profiles, ask the provider of your SIM cards about the APN, and fill in the blanks. If there's no special APN then it's just blank space.

Example: For example, if you have Verizon SIM at SIM1, and AT&T at SIM2, you are supposed to do this:

4.     Scroll up and set up SIM1 Network Provider/ SIM2 Network Provider according to the SIMs you put in. (If both SIMs are same carrier/APN, just pick profile 1 for both)

5.      Everything else could be left on default, then click apply at the bottom to save the change.

note: if the primary sim got disconnected, the router will redial 5 times before switch to the secondary sim. The redial number is controlled by "max number of dial". Each failed redial will cost about 2 minutes. If you need the sim switch happens faster, please lower the redial number accordingly.
