Two sims in use

[Guest carmel]

I've just Sim unlocked my c500 and I have an o2 sim with free texts that i want to use in it.

Trouble is all my calls will be on Orange contract.

Will i need both sets of network settings installed on the phone. What is the easiest way to do this,and how do i set it up to make it as easy as possible to use.

When you put a SIM in it will use those settings for voicemail and SMS etc. You cannot enter two seperate settings at the same time.
