RB4011IGS model Mikrotik i want to use LTE interface

No way, that RB have not USB port or mPCIe with SIM slot... means you not have possibility to install usb or mPCIe lte module....
You can buy separate lte device who give you a internet via Ethernet... and MikroTik to other MikroTik can send ssh commnads and that way you can triger SMS from RB4011

Please create separate a topic at forum and they help you.

But, please study this one what I always recommend:

I really recommended to learn and do this one HowTo who have got the best way to use many WAN's at ones.
Next you can use any method netwatch/script/pcc etc to just flow the outgoing - then this is small stuff.
