Lucky Mobile Number

The numerology number 9 resonates well with both the number 7 and the number 8

The number 9 also resonates well with your name number, which we refer to as the destiny number, the number 5. (What you're referring to as the destiny number, we refer to as the life path number.)

The number 9 is compatible with all single-digit numbers, as you can see in the compatibility table of the Compatible and Incompatible Numbers article.

Whether or not resonance is lucky depends on how you've defined lucky.

In numerology, lucky numbers are those that resonate with numbers in the person's numerology chart. A numerology number tends to attract events and circumstances that resonate with the energy it represents. If you wish to attract things that resonate with the energy the number 9 represents, then 9 is indeed a lucky number for your mobile.
