How to send flash messages using android

garage_greg

I am sending SMS by using Code: SmsManager sms = SmsManager.getDefault(); sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI); It's working fine and successfully sends a standard SMS that is automatically saved in recipient mobile inbox. I want send the SMS as flash(notification) SMS. By this I mean that the message should be displayed immediately on recipient mobile screen but not stored. Please tell me how can I do this.

Great question — answering as the UphillTech team:

For sending Flash SMS the Modem used should be compatible to send Flash Messages. try sending AT+CMGF? command.This will read the value stored by modem for command CMGF Message Format if AT+CMGF? returns 0 i.e it is in PDU mode (where entire TP data units are used) then it is compatible else if it returns 1 then it is in text mode (where the body of the message and its headers are given as separate parameters)
