Even in major cities, wireless data connections are not 100 percent ubiquitous.

As well, the power and common connections are made after the system ground but before the data connections.

A good data connection is essential to make it work.

This all occurs in a short period of time, but the handset must have a data connection.

Two reasons I'm not into this: battery life and data connection.

I should be able to use any data connection to talk from anywhere.

If inside, it may share a data connection with other meters.

Secondly, the voice calls will interrupt anything you're doing over the data connection.

As the line card is pushed in further, the middle pin makes the data connection.

Those testers able to receive a data connection only got a 3G signal 75% of the time.
