Great service.

When cellular service is bad, but Wi-Fi is available, it works great.

If you have no minutes left on your cellphone, Dingtone will still work.

Gives a real phone number that anyone can reach you at.

Excellent for having a second number on a cellphone.

Can use the same number among multiple devices.

Simple to maintain service, I have had the same Dingtone number for more than two years.
