YES!! - no worries

You can have 2 phone numbers assigned to 1 ESN. For whatever reason.
(Different plans, a business and a personal line, different areas, whatever...)
This is done all the time. Been there, done that - I have done it for years.

You CANNOT have 2 ESNs assigned to 1 number, repeat - CANNOT!!

So, using your below 'example', IF (and I mean if) someone were to somehow
successfully do an ESN change (your ESN to their number), YES your number
would be immediately deactivated and the new number activated.
This is how it's ALWAYS worked.

Key here is because it is a DIFFERENT ESN. Get it??

But, if I am not mistaken, there is verification done, preventing the 'hijacking' of
an ESN to prevent fraud.
