I've changed my number and tried to register in one service, but they told that this number has been already in use. I tried to change it again, but received: request couldn't be processed.
Are there any limits on frequency of changing numbers?
this is what I found however there is no mention about a limit on the number of times you can change your phone number. However depending on how often you want to change your number there is a $15 fee and a few other side effects.
