I just got off the phone with ZTE, and as usual, they're completely worthless! What I'm trying to find out is if any of the ports behind the back case are external antennae ports. I'm having a problem getting a strong signal and am exploring ways to boost (no pun intended), but my Boost needs a boost. The ports I'm referring to have little plastic covers. If anyone could lend me their tech knowledge, I'd appreciate it....
