Can I use the same Apple ID for two iPhone's?

You probably want different Apple IDs for iMessage and FaceTime; otherwise, you will get each other's messages

Here is how I solved that problem (iOS 11.1 and iPhone 8 ). We do not get each other's messages.

Settings > iMessage turned ON, below is Send & Receive > make sure that only the iPhones actual phone number is checked. Other iPhone should be unchecked.

FaceTime is also turned on.

FYI, Once the above is done it doesn't seem to matter that both numbers are listed under "a phone number I can be reached at" in iCloud. Settings > Name (at the top) > Phone Numbers, Email

I did separate our previous iPhones for about six months. I later put both phones on the same account and I like it much better. It just makes it easier for me to do maintenance and other sharing tasks when my wife and I are on the same account.

Yes, but there will be quirks. See: http://support.apple.com/kb/HT1495

What isn't obvious is that you can use different Apple IDs for different functions on your iPhone; for example iCloud, iTunes & App Stores, Game Center, iMessage and FaceTime can all have different Apple IDs from each other.

• If you use the same Apple ID for Find my iPhone then both phone's locations will show up at https://icloud.com/find. Which can be good or bad, depending on your situation.
• If you use the same Apple ID for iTunes & App Stores you can have the same apps and music on both phones; some or all of them.
• You probably want different Apple IDs for iMessage and FaceTime; otherwise, you will get each other's messages
• Also different for Game Center.

You can use the same Apple ID for purchases. But each should have your own iCloud account. iCloud account will allow you to sync your email, messages and other personal information to your phone.

You can use FaceTime (and iMessage) using your mobile number, but you will need to configure the phones to use it rather than your Apple ID.

To share purchases, use the same Apple ID in

Sttings > iTunes & App Store > Apple ID: > same Apple ID here

Am I right that you can use Facetime using your Mobile Number?

Yes

You have to use iCloud for email, calendar and other personal information if you use the same Apple ID.

If you use all the same information, same Apple ID and don't use the cloud, you will have all of each other's information on both phones. The phones will mirror any information synced with Apple ID.

You can use your phone number to use FaceTime on the iPhone. IMessage is also the texting application. You can use phone number for iMessage.

No. Only if you want to have an me.com or icloud.com email account.

How do you set up two phones to share one Apple ID? I’m trying to set up my husband’s phone and mine so we can share messages and FaceTime etc.
