Quick Note:
Scenario#1:
DUAL DSL wan links are connected with mikrotik [modems are in bridge mode], Configured as PCC along with the pppoe server. USB modem is attached with the Mikrotik via USB port. The OP need an script which can daily send sms or email specific information to admin cell, or whenever admin require on urgent basis via sending sms to mikrotik and it can return back the info to the admin cell.
Dirty Solution:
Following script will collect information from Mikrotik system such as active pppoe users, CPU load, dsl links status etc and send this information to admin via SMS or Email either via scheduler or as receiver command on mikrotik. [I am already using much more advance version of this script in other networks in linux system as BASH is the best ground to support scripting but since linux was not available at this spot, i had to use Mikrotik only with usb modem attached] it can be set as receive command too so that admin can send sms to mikrotik and mikrotik will reply back the current info to the admin mobile. Sometimes its very useful for remote admins.

Sample Image of SMS:
Enable Mikrotik to Receive SMS and run script
Use following command to enable SMS receiving on mikrotik.
#:delay 60 /tool sms set keep-max-sms=10 port=usb3 receive-enabled=yes secret=12345 channel 0 #:delay 3 #/tool sms set receive-enabled=no #:delay 3 #/tool sms set receive-enabled=yes
From your mobile you can send following message to run script on remote mikrotik.
:cmd 12345 script test
Explanation:
- :cmd to let mikrotik know that its command
- 12345 is secret which you configured in /tool > sms,kind of password / authentication
- script to let mikrotik know that its script related command and
- test is script name you want to run.
