is it possible to send wap settings to handsets via sms using //SCKL1581 or //SIAP11 instead of the WBXML approach.
In case it is possible may I send it using simple text sms or I have to encode it in a PDU aso in binary mode?
I've tried with a string like this but it didn't work
As the interface you operator is providing is not a interface provided by Nokia, I can't say if there is any way to go around this. You need to contact your operator if they are able to open your a binary interface.
