When will land line phones be unnecessary?

Please, note this question is not about why you may have a land line phone.

Many personal consumers still use a land line phone for many different reasons. Some do because there is no cell phone reception in their area. Some do for safety reasons, because a land line tells emergency dispatchers their location.

The vast majority of businesses use land line phones also for many reasons.

There are developing areas of the world where cell phones are growing greatly, because it’s easier to put up a cellular tower than it is to string lines.

How long do you think it will be before land lines are not needed?

Personally, I haven’t had a land line phone for a decade.
