got one issue to share.
Right now , we're building a smsc on fixed line interfacing with various mobile operators throughout Malaysia.
The problem is whenever we send sms to phone with Symbian OS (our test platform N91), sender number appeared on the phone goes something like this.
"?" sign appeared at the end.
But, when we send to other phone without Symbian likes Sony Ericson K510i, it works fine.
Could you give us some clues, why this thing happens ?
