>>you want both SIM's to be active at the same time??
Yeah- they call it "dual standby" meaning they're both active until one enters a call. If you look for "dual sim" on eBay there's heaps of options, though most have poor touchscreens and are using the Chinese Nucleus OS that allows some Java apps to run but none of the cool apps people want.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
