Dear All,

Need some feedback from you guys, please assist (thanks in advance): -
- Am currently Maxis user (ported out from Celcom 2 weeks ago)
- Using 16GB iPhone 3GS with 3.1.2 and 5.11.7
- Problem discovered - while on GPRS/EDGE, Data has got higher priority than Voice.  I.e. while there is data connection established, your voice will be routed through Voicemail.  Of course this won't happen on 3G/HSDPA connection.
- To test the above - Turn Off 3G, then load any heavy website.  While it's loading, quickly use another phone to call your iPhone.

Would appreciate if Digi (iPhone) user can assist on the below as well: -
- Turn off 3G
- On your dial pad, please key in *3001#12345#*, then choose "GSM Cell Environment", then followed by "GPRS Information", then please advise the value of "Network Operating Mode".  If it's 002, I would assume you will have the same problem which I am facing.  If the NOM is 001, then I guessed the Voice should have higher priority than Data - LUCKY!
- Tested on some Celcom and Maxis transceiver tower, so far, all are running on NOM 002   sianz....

Thank you all and hope to have some feedback, enjoy your day ahead.

Regards,
Seb
