sms sending failed

Without the package the modem won't switch to the required mode. Install the package again then run this script once:

Code:

data = [[
return {
  messages = {
    "55534243123456780000000000000011062000000100000000000000000000"
  },
  devices = {
    ['12d1:1f01'] = {
      ['*'] = { msg = {0} }
    }
  }
}
]]

io.writefile('/lib/usbmode/data.lua', data)

This will use a different switch message for your modem. Seems that different modem firmware versions require a different message. You can try different messages from the post that you've linked before.
