What message are you getting on the screen when you turn the phone on? Is it recognising there is a sim card there but not letting you use it? The most common reason for this is often a 'Locked' handset. Most networks set the phones the sell to only work for their sim cards. Most specialist phone retailers can usually Unlock the handset for a small fee.
If it isn't recognising that there is a card there it will either be a faulty sim card or a faulty phone.
This phone was first released in 2008 and Sony's support for mobile phones by an agent is discontinued. In short, calling Sony for support won't help. The T700's technology was GMS/HSPA. T-Mobile and AT & T are carriers which access such. Whether either would assist you with setting up network connections is unknown to me. It sounds like your query involves the basic setup. I would review that in relation to the feature you are attempting to access and then query your carrier. But that route may offer no joy. The user manual has a troubleshooting section Here is the user manual for the T700 but there is a real question of your access to software updates for a 2008 release phone. I have no idea of the veracity of the service that claims to offer repairs or unlocking for this phone. This looks like an exercise in frustration. Sorry.

Unless you had an app like LookOut or Prey (highly recommend both) it is highly unlikely. Try talking to your service provider and see if they can track the GPS, otherwise you are SOL.
