Hi everybody,

I unlocked my phone 2 days ago and I'm successfully using it here in Serbia on the Telenor network, everything is working fine except the messages which you get from your operator telling you which numbers called you while your phone was out of signal. As I travel a lot in areas where signal is weak i really need this feature and I don't like voice mail as most people just hang up when they hear the secretary.

I tested this a few times in the last two days, i turn of my phone and call from as many other phones as I can, I wait a while and turn it on but I haven't received a single missed call message yet.
I called the service center and they said that i shouldn't be having any problems, and they reset my missed call service just in case. I tested again and still nothing.

Is this a problem with the iphone or should i pester my operator more?

Any solution is welcome. Thank you in advance.

-=EDIT=-
I've just dialed *#61# on my phone and amongst other things it says
Setting interigation Suceeded
SMS Call Forwarding
When Unanswered
Disabled

Is this the problem? Any thoughts?

-=EDIT no.2=-
I have just tried to use the web2sms service on my operators site to send a message to my phone and it inst arriving.
It seems that I can't receive any messages from my operator?! All other messages come in just fine!

Anyone help please, this is really getting on my nerves.
