What’s it like to have three different region Apple IDs signed in on one iPhone at the same time?

Ever since going overseas, I’ve been using more and more apps like Hong Kong banking and US stock trading ones. With so many accounts, apps downloaded from different regions require repeated logins and verifications during updates.

Recently, I discovered a handy little trick officially supported by Apple—it’s super simple and super useful:

My Hong Kong version iPhone running iOS 17 has three region Apple IDs signed in

• Main China region: iCloud sync enabled (photos, contacts all here)
• US region + HK region: Dedicated to managing apps from their respective regions, updates are seamless

How to do it? Done in 10 seconds—check the next post.

Setup steps (works on both old and new iOS):

1. Open Settings and use the search bar at the top to search for Mail.
2. Mail Accounts → Add Account → Select from list.
3. Key step: Choose iCloud, don’t pick the wrong one.
4. Enter another region’s Apple ID and password, then tap Done.

This way, your device simultaneously “trusts” multiple accounts:

• Updating apps under these accounts no longer prompts for verification codes—very smooth.
• To download a new app from a specific region, you still need to switch accounts at the top of the App Store—but you won’t have to enter a verification code again, which is much faster than the old method.
• Small reminder: Only sign in with your own accounts, don’t sign in with random unknown Apple IDs.

If this is useful, tap like + save, and share with your iPhone-using friends.

You don’t need to, after you download the app, you can just update it directly later.

Actually, the core principle of this method is to add the device to the Apple ID’s trusted device list and make it permanent; everyday App Store account switching stays the same.

As a long-time Apple fan, I have multiple region Apple IDs, but for iCloud I still trust the China region. Speed and stability are what matter most.

Bro, this has actually been an old Apple trick for a long time—just signing in with multiple accounts on the device, no risk of getting banned.

Yeah, having to verify every time is still a hassle. But 2FA is important, so you can’t turn it off.

It’s a headache if you have multiple devices.

After setting it up, switching is much better. Before, I had to use another device for two-factor verification every time—that was even more annoying.
