I'm trying to send a plain text message with special characters in 8-bit using CIMD. But I get a "Message cannot be displayed here" in my phone.
I'd like to test sending special characters in 8-bit because the telco i'm connected to hav problems in sending special characters in 7-bit format. I tried sending _Oa but I got _Oa instead of @ sign in my phone.
The packet i sent is below. Pls comment what is wrong.
Don't know about the CIMD protocol, but I'd assume there's some problem in the headers you're sending. Are the bits right to indicate that your data is indeed 8-bit? See the SmartMessaging FAQ and perhaps GSM SMS spex to clarify.
