Through Looking4U, the called customer will always be alerted in case your call will not be successful (busy, not reachable, off, voice mail).
Looking4U will alert the customer for you, by sending a text message via SMS or via WhatsApp from your mobile phone.
Moreover Looking4U allows you to customize the text message to be sent, so for example the called customer will receive a message like: "Hello, this is Dr. Joe Black, I tried to call you, could you please call me back".
Check with your mobile operator if you already have active a notification service and if you're paying.
Suggest Looking4U to your friends and your relatives and everyone can take advantage of this convenient service!
