Prophet driving me crazy

[spinny]

I have a Prophet G4 which appears to be unlocked - however I put my Orange sim in no problem works like normal. I put my pay as u go 3 Sim in and I can make and recieve calls but tells me the service provider is Orange !!!! I know it's 3 because I dial to check my balence. Ok when i put my 3 contract sim in the phone it tells me there is no sim! The sim works ok in my 3 phone. Where am i going wrong? What do I need to do I want to use my 3 contract sim in the Prophet!!!

Please advise, I wait in anticipation

Phone is a SPV M600 ruinning Windows Mob 5 and SPL 2.20 IPL 2.20 if i try to add a new rom it just keeps going to three colours bootloader.

Hi Spinny, I'm not sure if this is right but I think the prophet is not a 3G phone ( which uses the UMTS connection) but is a 2G phone running on GSM. Your phone is probably unlocked and able to use sims from T mobile ,Orange ,O2 and Vodafone etc.
As far as I know , 3G phones run on UMTS when there is an available connection but will switch to GSM when the UMTS not available. Therefore it connects to your Orange network and works but you will be getting billed by 3 network and you wouldn't be able to use video calling.Hope that helps. There is a lot of info here too http://www.pdadb.net/index.php?m=specs&id=456&view=1 :)
