Error description:
If you "Google" for this "Network out of order" error message you'll most likely find the following description.
- Cause no 38: "Network out of order"
This cause indicates that the network is not functioning correctly and that the condition is likely to last a relatively long period of time; e.g., immediately re-attempting the short message transfer is not likely to be successful.
Possible cause:
This problem usually isn't caused by a malfunctioning GSM box, defective SIM card or a bad network signal. It can never hurt to check though. So make sure there are no defects and that the signal strength is high enough.
The most common cause is a forced limit by the mobile network operator.
Possible reasons for this limit:
- The operator wants to reduce the load on its network.
- The operator thinks that your SIM is spamming messages.
- Contract for you SIM card changed from "heavy use" to "normal use"
Solution
Things to do:
- Check if you have a special SIM card for heavy usage or not.
- Does the operator know that this SIM is used for a lot of traffic?
- Talk to the mobile network operator, inform them about your problem and ask what can be done about it.
