Keeps your contacts up to date
We cannot stop people from moving or changing their phone number. We also cannot expect them to inform everyone that their contact information has changed. When a contact info is updated in Dubb, or someone changes a person's contact information you will be notified and be given the option to update their info.
With Dubb your contacts are always relevant, up to date and useful. Social messaging apps such as WhatsApp and Viber work based on phone numbers, so get the most of them by leveraging Dubb to expand your contact list!
