Kyocera Wild card circuitry layout

Hi i recently came into possesion of a wild card my friend busted. the bottom still seems to buzz upon being turned on and off and after wire resodering i got the sound working but i cant call or text or receive texts. I was wondering if anyone knew the location of the antenna or the best place to connect a new one. thanks

How busted up was the phone?

Was it able to send/receive data or do the same with calls when you got it?

Did you disassemble the case before removing the circuit boards?

Were you familiar with the functions of everything mounted to them?

Was the area around where you soldered thoroughly protected from the molten stuff dripping through? Soldering can be very tricky on components that small.

The problem may not have been from just the loose speaker.
