Tiptop Keep in Touch helps you to stay in touch.
You call a correspondent but a message tells you that you have no more credit. All you have to do is redial your correspondent’s number, followed by #. An SMS will then be sent to the person in question asking him or her to call you back.
This procedure is clearly notified to you by a voice message.
You do not need to ask for the Tiptop Keep in Touch service, it is now available for all Tip Top customers.
Simple and free.
