My Aria was stolen last week so I bought an Inspire. After activating it I could not connect to the internet(mobile network) I get a "connection failed due to incorrect APN setting" message. I called AT&T tech and they said my unlimited data plan is only 3G and the Inspire will not work with 3G only 4G. They want me to switch from my unlimited data plan ($20/month) to a 3GB plan($30/month) and then they say my mobile network should work. I am happy with 3G and don't want to spend another $10/month for less data even if it is faster. Can I make the Inspire work with 3G?
