You'll need to post a bit more information than that if you want assistance from the Community Forum.
What do you mean by "reactivate my phone number"?
What are the symptoms of the problem?
When did you last successfully buy a membership plan?
What happens when you use this link to try to buy one now?
Any error messages?
If your account/number has become suspended because you didn't buy a membership plan for 6+ months then you'll have to contact 48 support for assistance with getting it working again.
See the links in my signature below.
Is this issue related to your previous one last year by any chance?
