If you're an AT&T customer, you might wonder why your internet isn't working even though you have full bars. There are a few possible explanations for this: 1. AT&T's network is notoriously finicky, so your phone may be just having trouble connecting to the internet. 2, Even if your phone is connected to the internet, AT&T's speeds are often very slow, so you might be unable to load websites or use apps correctly. 3. AT&T may be experiencing an outage in your area. If that's the case, the best thing to do is wait it out and try again later. Hopefully, one of these solutions will help fix your issue!
