LtAP Dual SIM Setup

Hi guys, can you please enlighten me as to how to setup Dual SIM on the LtAP? I would like to insert two SIMs from two different mobile providers and then if the main SIM (Sim Slot 1) loses connection then it should automatically connect using SIM 2 (Sim Slot 2).

What would I need to do to make it work like mentioned above?

You can paste that script in System - Scripts menu also in Winbox. Just read the commands that are specifed, and click on appropriate menus in Winbox.

other clarification please .. I have two sims and I have created two APNs. how can I tell SXT “use APN1 for SIM # 1 and APN2 for SIM # 2”?
I read wiki https://wiki.mikrotik.com/wiki/Dual_SIM_Application but I do not think there is an explanation for my request. can you help me?

Add APN profile selection line together with changing SIM slot line:

/interface lte set lte1 apn-profiles=...
