Setup the LG-E900 on AT&T

The LG-E300 is very much like the LG-C300 from AT&T. I like the phone. However, since it is not an AT&T phone, getting it to work on the AT&T network is not as simple as plugging in the SIM. I’ve compiled your steps:

Get 3G Working

1. Open Settings
2. Choose ”Cellular“
3. Scroll to “Set or Edit APN”
   APN:  wap.cingular

   Password:  CINGULAR1
4. Save, Click Start

Cheers to here for this information.
