<human>:  I need to change my phone number, what do I need to do?
<bot>: First, you need to contact your phone service provider and request the change of your phone number. They will usually ask you for proof of identity so that they can verify that it is really you who is making the request. After your request is processed, you will get a confirmation of the change. You may also need to update any online accounts or databases that still use your old phone number.
