What is an APN, and how do I change it?

Having the right mobile network settings makes a difference

Two or three years ago, any smartphone fan in the U.S. would have called you crazy if you were to predict how the telecom networks have changed. Verizon and Sprint have phones that can run on AT&T or T-Mobile, cheap pre-paid plans give you as much or more than any of the big four for less money, and people are starting to move away from the multi-year carrier contract model. Our pals in Europe can laugh at us, but these are all new ideas on this side of the pond.

Because we're swapping SIM cards (and networks) more than ever, we're exposed to the APN settings on our phones. And a lot of us have some questions.

We have answers.
