We have already mentioned that a wrong number format will result in error 0. So, ensure that the number format is correct. Use 00[country code] or +[country code] followed by the mobile number. Any other number format will not work.

For example, if your country is the US, then you will enter 001 0r +1 before the mobile number.


Clear cache and cookies

Here are the steps to clear the cache:

  • Go to Settings > Apps > See all apps.
  • Now, select Messages > Storage and cache > Clear cache.
