Therefore, for your convenience, before we jump straight to that, here are the reasons why users want to get their deactivated phones back. 

Why Does One Need a Deactivated Phone Number Back?

When a phone number isn’t used for a long time, it’s common practice to deactivate it. Even if the line with the number is kept active and not paid or recharged on time for the phone number, this can happen.

Most carriers have an automatic deactivation policy that operates on a 90-day basis. When a phone line isn’t utilized for a certain time, it is automatically deactivated. The phone number will be recovered after another window.

There are many reasons behind these restrictions, but it’s simple to conceive a situation where someone moves out of the nation permanently but forgets to disconnect their phone line.

Automatic payments can keep things going, but they aren’t beneficial to either party. The same might be stated about a line holder’s death and a variety of other scenarios.

A second case in which a phone number is disabled occurs when a phone line is effectively canceled. 

When a phone number is linked to a cancellation line, it is usually recycled more quickly. Depending on the circumstances, a phone number can be revived in a short duration of 30 days.
