Message platforms Signal and Telegram have both seen a huge surge in downloads around the world following a controversial change in WhatsApp's terms and conditions.

WhatsApp has told its two billion users they must allow it to share data with its parent company Facebook if they wish to continue using it.

The change does not apply to users in the UK and Europe.

However, the notification has been sent to everyone.

All WhatsApp users will be unable to continue with the service unless they accept the new terms by 8 February.
