I experienced problem with 9210 when receiving messages sent from application through SMS-C.
If I use some alpha origin e.g. "Nokia", Answer button is not shown which is OK behavior. But if I put numeric origin in international format e.g. +41791234567 Answer button is still not shown. If I send same message to other phones (other Nokias, or other manufactures) it works OK and I can reply to message.
I've tried testing with several 9210 phones and got same problem on all of them.
Anyone experienced same problem? Any idea what could be the reason ?
