Welcome to Android Central! First, you need to make sure the phone supports your carrier's network bands. Which exact G3 model do you have? Is it a Verizon/Sprint model (CDMA), T-Mobile/AT&T (GSM), or unlocked (usually GSM)? Which carrier do you have?

Assuming the phone is compatible with the carrier's data network, you should also check to make sure the APN settings are correct. What is an APN, and how do I change it? | Android Central
