If you can’t purchase music from the iTunes Wi-Fi Music Store
To purchase songs from the iTunes Wi-Fi Music Store (only available in some countries),
you must have an iTunes Store account, and you must have been signed in to that
account when you last synced iPhone with iTunes. If you get a message that no
account information is found when you try to purchase music, open iTunes on your
computer, sign in to your iTunes Store account, then connect and sync iPhone.
If you can’t make a call or send a text message over Wi-Fi
iPhone doesn’t support calling or texting over Wi-Fi.
Removing the SIM Card
If you need to send your iPhone in for service or if you want to loan your iPhone to
someone and you still want to be able to make calls, you may be able to use the SIM
card inside iPhone with another GSM phone.
Remove the SIM card
Insert the end of a small paper clip (or the SIM eject tool if it came with your iPhone)
into the hole on the SIM tray. Press firmly and push it straight in until the tray pops out.
