Im new to this so I hope Ive got the right Forum.
We have been asked to take a cheap entry-level phone and modify its functionality in the following way.
1. To create an ‘SOS’ function invoked by pressing
simultaneously two buttons on the phone. Or by pressing two buttons in quick succesion. The phone would automatically dial a pre programmed number stored on the SIM.
2. To reduce the outgoing call capability to a list of say five pre-programmed
numbers which the ordinary user would be unable to change.
I need to get a feeling for which low cost phones I could use to modify their functionality as required.
Phones like the 1101 and 1600 are cheaply available in this country
All help is greatly appreciated.
