I am currently trying to send stealth SMS from one mobile phone to another using AT-commands and setting PDU header field TP-DCS to "discard message" as well as "Set Indication Inactive". This seems to work on most phones, but on Nokia 6600 it works partially. The first few sms messages are invisible at the receiving phone, but then a visible sms pops up and is stored in the inbox on the receiving phone, followed by a few invisible sms, before it all is repeated again. Does anyone have an idea what the reason may be for Nokia 6600? All the SMS messages are set up identical, and are sent every 30 seconds.
Or may there some other way to accomplish this?
