How to use android phone # as apple ID

Hi chanya,

If you do mean "as" as Apple ID, you can only use a telephone number as an Apple ID in certain countries. See the document Use your mobile phone number as your Apple ID - Apple Support

If you do mean "with", I presume you mean in the context of two-factor authentication. And Android can't be used as a trusted device but you can use it as a trusted telephone number to get a verification code. This is from the section "About trusted phone numbers and trusted devices" in the article: Two-factor authentication for Apple ID - Apple Support :

To see, add, or change your trusted phone numbers use a web browser: Go to the Account Security section of https://appleid.apple.com .
