Barring a hardware problem, I know of only two things that could cause this.
1. Wrong or incomplete APN settings. You already mentioned this, but make sure you have the right settings for HSPA+ (what the Infuse uses), and not LTE (for example).
2. The SIM is not properly provisioned for that phone class. AT&T can verify and/or replace your SIM at no charge if you are already a customer.
