Hi, I need help changing the mobile network on my Cingular 8800 with OS 4.2.1.72, right now I'm roaming internationally and I've been trying to change the network in the Options -> Mobile Network menu and I don't have any way of choosing the network manually.

Can any of you let me know if this is a locked feature in the Cingular OS oor if by updating/upgrading the OS I would have the option in my 8800?

I also have Pearl 8100 from a local carrier that has this option and works fine with the different networks in this country I just don't know why Cingular would not allow this.

Thanks,

It's usually a provisioning thing through the sim card. Can you try your Cingular sim card in the local carrier Pearl (if it's not unlocked?)

Hi, thanks for your quick reply, I tried changing the SIM but it's locked. Any other suggestion?

Hi John I was able to unlock my 8800 and try it with the local SIM card which is BIS and it works I get the "Network Selection Mode" option that I'm missing with the Cingular SIM card.

I've called them (Cingular) several times and no luck, nobody seem to know what's wrong.

Any suggestions?
