17. Problems • No debug tools, all testing is done on the phone • long edit/compiler/debug cycle • lack of simulator • disassembler for PDU’s • Script language is extremely limited • hard to use syntax • lack of instructions (swap arrived too late in the update) • no variables • Suspect card to miss ESMS processing when phone is busy • Instruction set SIM card and security info is kept secret • we reversed engineered it partly at great cost of time

18. Future • Limited application area for SIM Application Toolkit in the future after 3-5 years: • WAP • IP connectivity • Very convenient today for accessing many different services • Operators need to make it more open to make it useful for third party developers • Cell identifier is a very interesting possibility for location based services
