Old cellphone networks are being shut down and more than old phones will be affected.
On Tuesday, AT&T switched off its old mobile technology known as 3G. Other carriers including T-Mobile and Verizon plan to follow suit later this year.
While there may not be a lot of old 3G-only phones still in use, experts warn that home alarm systems, e-book readers and other devices that use cellular modems may need to be upgraded or replaced.
