Globe Visibility: Problem Connecting in Crowne Plaza

I was trying to connect using my newly bought Globe Visibility
Prepaid, Huawei E160 USB modem, but it seems like it having a hard
time connecting to Globe even if I'm getting a pretty decent signal.

I found the problem, the settings are set for PostPaid while I'm
using a prepaid USIM. Looks like I'm not getting enough signal in the
conference hall.
