Cannot connect to 3G network using supplied app. Can someone help?

Question

I am resubmitting this question reworded for clarity, I hope.
I'm in Nicaragua for several months and as a non-resident can't get wired internet to my house. Most people I know use a 3G or 4G dongle from Claro, one of two providors in Nicaragua. I bought a 3G dongle today, plugged it in, installed the Turbonett Movil app, and... nothing. Deleted the app, restarted and installed again but still nothing.
Can anyone help me with this? I can't afford to throw away the $70 it cost for the dongle and one month's service.
Thank you for reading this.

Answer 1

Sorry to tell you but this is a real problem with Mac OS X.
Apple suggests that the printer be connected to the computer Via USB port while installing it.
Yes you heard me right.
Read this article.
http://support.apple.com/kb/HT4670
From that article.
If the printer is a wireless capable printer and it is connecting to a wireless network, make sure it is properly connected to the wireless network first. The printer may have to be connected to the Mac initially via USB.
Although it states that if the printer has wireless capabilities but it really doesn't matter if it does or doesn't. If it is a networked printer you may still have problems connecting to it
