Suggestions please - Giving old iPhone 4 to a distant relative. I can activate it fine after wiping it because it has an old SIM in it (inactive) with my phone number. Question: How do I, after activation, make sure that phone number can't be used for iMessage/Facetime? I don't want the poor kid receiving iMessages and facetime calls sent to my phone number when he's on WiFi (my phone number is still active with the carrier on my iPhone 5S and tied to iMessage/Facetime) Anyone had any experience with turning an iPhone into an iPod Touch while also making sure the phone number tied to the installed dead SIM doesn't enter Apple's facetime/imessage ecosystem? Thanks in advance!
