1. Replace AT:read() function in user.sms with the following code.
2. Restart the SMS script.
3. Post what you have in Logs when this issue happens again.

Code:

function AT:read(timeout)
  local char, err, timeout, deftimeout, line

  -- default timeout is 1 second, converted to 0.1 sec ticks
  timeout = tonumber(timeout) or 1
  timeout = timeout * 10

  deftimeout = timeout

  -- read until got one line or timeout occured
  while timeout > 0 do
    -- read 1 char
    char, err = self.port:read(1, 0.1)

    -- got data
    if char then
      -- got LF, end of line
      if char == '\n' then
        -- convert to string and empty buffer
        line = table.concat(self.buffer)
        self.buffer = {}
        line = line:trim()

        -- return only lines with data
        if #line > 0 then
          log('read line', line)
          return line
        -- reset timeout
        else
          timeout = deftimeout
        end
      -- ignore CR
      elseif char ~= '\r' then
        table.insert(self.buffer, char)
      end
    -- read timeout
    elseif err == 'timeout' then
      timeout = timeout - 1
    -- other error
    else
      break
    end
  end

  log('read timeout', self.buffer)
  return nil, err
end
