Do you know what does the E (or 3G) next to the AT&T logo on your iPhone stand for ?
- AT&T E means your phone is using EDGE network signal.
- AT&T 3G means your phone is using 3G Network signal.
EDGE is a third-generation technology. EDGE is a slower network, but with EDGE network you can watch video, listen to music clips etc. 3G is the faster network, it gives you the accelerated data speeds and simultaneous voice and data capabilities. With 3G you can use voice and data at the same time.
If 3G network is not available in your location, you will receive service on the AT&T EDGE network in your phone.
