How to activate new device without access to other devices and SMS? I am going to travel to the USA next month and I'm willing to buy a new iPhone. Currently, I have a Mac and an iPad and an Android smartphone. When in the USA, I will have neither my Mac nor my iPad with me, and I won't be able to receive SMS through my Android device.

I have two-factor authentication turn on. I don't see how to turn it off on Apple ID page. Is there any way I set up my new iPhone without carrying, let's say, my iPad with me for the trip?
If the new iPhone is set up with the same Apple ID as your other devices you need to turn off Two Factor Authentication for the Apple ID.
If you're using iOS 10.3 or later:

Go to Settings &gt; [your name] &gt; Password &amp; Security.

Tap Turn Off Two-Factor Authentication.

Tap Continue.


If you're using iOS 10.2 or earlier:

Go to Settings &gt; iCloud.

Tap your Apple ID &gt; Password &amp; Security.

Tap Turn Off Two-Factor Authentication.

Tap Continue.
