Q: find my iphone button not response in setup

Hello there, EdmundLow.

It seems you're having issues with setting up your new iPhone 6s. The following Knowledge Base article offers up some great guidelines for troubleshooting setup issues:

If you can't activate your iPhone

Before you begin

• If your iPhone uses a SIM card, make sure the card is in your iPhone. Even without an active contract, your iPhone might still need the SIM card to activate.
• If you see a No SIM card error, follow other steps. No SIM or Invalid SIM alerts appear when a SIM card is damaged, locked, or missing. 
• If a message says to sign in with an Apple ID to activate, learn about Activation Lock.

Follow these steps 

1. Find the list on the system status page. If the box next to iOS Device Activation isn't green, try activating your iPhone later.
2. If asked for a password, enter it. A password prompt means Activation Lock might be enabled in Find my iPhone.
3. Restart your iPhone.
4. If you're using a cellular data connection, try connecting to a reliable Wi-Fi network instead. If a Wi-Fi connection doesn't work, try connecting to iTunes.

Get more help

1. Contact your carrier to check for network or activation issues, or if necessary, to replace your SIM card.
2. Use recovery mode to restore your iPhone. 
3. If restoring your iPhone still doesn't work because of an activation error, contact Apple Support.
