This simply an easy task, where you just need to apply the PIC microcontroller and connect it with your Ericsson T18 series phone (You can also test this stuff with the A1018 and T28 series as well).
This method only good for own personal use, if you want it to be commercialized, it’s meet the difficulty of finding the suitable connectors in large amount (Go on and try to commercialize it if you did found a good supplier, which can provide you those needed connectors in low price).
