How to send an message to more than one with RD2030
This is the only way I found
Preset the phone, to save a copy in sent folder.
Go, to zero signal zone, or create one by removing antennae in weak signalzone.
When there is no signal, phone will not send an sms but save and defer it till it has signal.
Keep, piling up messages in sent folder, doesnt take much time if your sent folder is empty. It saves quickly.
Once you have saved some ten messages or more, (takes 20secs) put on the antennae or go to signal zone,
Now lay back and watch as the handsets SHOOTS one message after the other into the network.
