Modify AT:run() function in the user library as follows and post what you get in LM Logs tab.

Code:

function AT:run()   local res, err, cmd, pos, sms   res, err = self:read()   if err then     if err ~= 'timeout' then       log('run error', err)     end     return err == 'timeout'   end   -- check for incoming command   if res:sub(1, 1) ~= '+' then     return true   end   pos = res:find(':', 1, true)   if not pos then     return true   end   -- get command type   cmd = res:sub(2, pos - 1)   -- check only for incoming sms   if cmd ~= 'CMTI' then     log('run cmd', cmd)     return   end   -- read from sim   sms = self:incsms(res)   -- sms seems to be valid, pass to handler if specified   if sms and self.smshandler then     self.smshandler(sms)   end   return true end
