How to disconnect iPad from verizon phone number

Question

I gave my old iPad to my son and would like to disconnect it from the verizon number it is associated with, so that he only uses wireless. How do I do this? Thanks!

Answer 1

1.  If the iPad has a cell module, you'll first need to disconnect the cellular service through Verizon.  Second, be sure Cellular Data is disabled on the iPad.  Then disassociate other services (such as those below). 
2.  If the phone number is associated with the iPad only for FaceTime and iMessaging:
Settings - for each of the following, be sure your phone number is no longer populated:
Phone - "My Number" should be blank (or not available, depending on iPad model)
Messages 
If he won't be using iMessaging turn the option 'OFF'.
If he'll be using iMessaging, turn this option 'ON', then
Scroll down to 'Send & Receive' and touch the field: 
Your phone number should not be included.  If it is, UNcheck the field
You should have an option of using an Apple ID or another email address - enter the information you wish to have the iPad use to send & receive iMessages
FaceTimeUse the same guidelines as above, for iMessaging
3.  If your son will use his own Apple ID on the iPad, be sure to decide whether or not to change settings for Find My Phone (iPad).  If you change the settings for this feature, you'll need to log onto www.icloud.com with your Apple ID and disassociate the iPad from your iCloud account.
Hope this helps!
