# How to set up a burner iPhone for everyday privacy

> A burner iPhone keeps a second number and account apart from your real one; it's a privacy tool, not a way to become anonymous.

## Quick answer

A burner iPhone is a second number kept apart from your main one. The simplest setup is a prepaid eSIM line, either as a second line on your own iPhone with Dual SIM or on a spare iPhone with its own Apple Account. Then share little data: separate email, limited location and tracking. Your carrier still knows who pays.

- **Easiest option:** Add a second eSIM line to your own iPhone: Settings -> Cellular -> Add eSIM.
- **More separation:** A spare iPhone with its own prepaid line and its own Apple Account.
- **Privacy settings:** Limit Location Services, turn off Allow Apps to Request to Track, use a private Wi-Fi address.
- **Not anonymous:** Your carrier, Apple and your apps still hold the details you gave them.

It depends on how much separation you need. For most people, a burner iPhone means a second phone number kept apart from their real one: either a prepaid eSIM line added to the iPhone they already carry, or a spare iPhone with its own prepaid line and its own Apple Account. Add a separate email, tight location and tracking settings, and the people you meet through online marketplaces, dating apps, a side business or travel never get your main number or your iCloud data. What it isn't is anonymity: your carrier, Apple and your apps still hold the details you gave them, and a burner doesn't change what's legal.

We checked these steps against Apple's iOS 27 documentation and T-Mobile's prepaid eSIM page in October 2026.

## What a burner iPhone is, and what it isn't

A burner is a number and, ideally, a device that you can give out freely and drop later without changing your real number. Good reasons to want one:

- **Selling online or meeting strangers** from listings and dating apps.
- **A side business or volunteer role** you want kept off your personal line.
- **Travel**, where a local number is cheaper and easy to discard.
- **Leaving a bad relationship**, where a fresh number and account the other person has never touched is safer. If that's you, also run Safety Check on your current phone; see [how to tell if someone went through your iPhone](/blog/signs-someone-went-through-your-phone).

It isn't a way to hide from carriers, Apple, apps or legitimate legal processes. Signing up for a phone line means giving the carrier information, and every app you install sees what you allow it to see.

## Option 1: a second number on your own iPhone (Dual SIM)

You don't need a second phone to get a second number. Apple's Dual SIM feature gives one iPhone two active numbers, with a physical SIM and an eSIM, or two eSIMs on iPhone 13 and later. It works on iPhone XS, XR and later.

1. Buy a prepaid plan from a carrier that supports eSIM.
2. Activate it in **Settings -> Cellular -> Add eSIM** using the carrier's QR code, app or eSIM Carrier Activation.
3. **Label your plans**, for example Personal and Burner, under **Settings -> Cellular**, then tap the number and **Cellular Plan Label**.
4. Choose your **default number**, which iPhone uses for anyone not in your contacts, and which numbers iMessage and FaceTime use.
5. For a contact who should only ever see the burner, open the contact, tap **default** and pick the burner line.

Apple notes that to use two different carriers, your iPhone must be unlocked by your carrier, or both plans must come from the same carrier. The phone uses one cellular data network at a time.

## Option 2: a separate iPhone with its own line and account

A spare iPhone gives real separation: different number, different Apple Account, different photos and contacts. It's the better option when the burner shouldn't sit next to your real life on the same device.

1. **Get a phone that can take any carrier's eSIM** Use an iPhone XS, XR or later that's unlocked for use on other carriers' networks. If it came from a carrier, ask them to unlock it.
2. **Erase it if it was used before** Go to Settings -> General -> Transfer or Reset iPhone -> Erase All Content and Settings so nothing from a previous account remains.
3. **Create a separate Apple Account during setup** When asked to sign in, tap Forgot password or don't have an account?, then Create a Free Apple Account. Use an email address you keep only for this phone, set up two-factor authentication and choose None for payment if you don't plan to buy anything.
4. **Activate a prepaid eSIM line** Buy a prepaid plan from a carrier that supports eSIM, then activate it with the carrier's QR code, app or eSIM Carrier Activation: Settings -> Cellular -> Add eSIM.
5. **Tighten privacy settings** In Settings -> Privacy & Security, limit Location Services per app and turn off Allow Apps to Request to Track. In Settings -> Wi-Fi, set Private Wi-Fi Address for each network.
6. **Keep it separate** Don't sign in with your main Apple Account, don't restore a backup from your main iPhone, and add only the contacts you need on this number.

For example, T-Mobile's prepaid eSIM page lets you activate on the web if the device is unlocked: you check compatibility, pick a plan, enter your name, email, ZIP code and payment method, then scan a QR code to install the eSIM. Your new number appears on the confirmation screen and in a welcome email. Apple adds that in some countries and regions, activating an eSIM requires an in-person ID check at a carrier store.

## Which setup should you pick?

| | Second line on your iPhone | Separate burner iPhone |
|---|---|---|
| Extra hardware | None | A spare unlocked iPhone |
| Apple Account | Your main one | A new, separate one |
| Photos, messages and contacts | Shared with your main number on one phone | Kept apart |
| Who sees which number | You choose per contact and per message | Only burner contacts ever see it |
| Risk of mixing them up | Higher: one Messages app, one call log | Low |
| Easy to drop later | Erase the eSIM | Erase the phone and the eSIM |

## Create a separate Apple Account

On a separate burner iPhone, don't sign in with your own Apple Account. Everything that syncs, from iCloud Photos to Messages in iCloud, would land on the burner.

During setup, tap **Forgot password or don't have an account?**, then **Create a Free Apple Account**. Enter a birthday and name, then an email address that becomes your sign-in. If you don't have a spare address, Apple offers a free iCloud email at that step. Set up two-factor authentication, and choose **None** for payment if you won't buy anything.

Apple will ask for a phone number to verify your identity and recover the account. Use the burner number itself if you want the account fully separate, and keep the password somewhere safe: without it, you may lose the account and the ability to reactivate the phone.

## Privacy settings to change on a burner iPhone

| Setting | Where | Why |
|---|---|---|
| Location per app | Settings -> Privacy & Security -> Location Services | Give apps location only when needed; turn off **Precise Location** where approximate is enough. |
| App tracking | Settings -> Privacy & Security -> Tracking | Turn off **Allow Apps to Request to Track** so apps can't ask to track you across other companies' apps and sites. |
| Private Wi-Fi address | Settings -> Wi-Fi -> More Info next to a network | Choose **Rotating** or **Fixed** so the phone uses a different Wi-Fi address on each network. |
| Notification previews | Settings -> Notifications -> Show Previews | **When Unlocked** keeps messages off the Lock Screen. |
| iMessage numbers | Settings -> Apps -> Messages -> Send & Receive | Confirm which number and email iMessage uses. |
| Hide My Email | Sign in with Apple, or iCloud+ settings | Sign up for services with random addresses that forward to your inbox. |

## Who can see your burner number and data

| Who | What they can see | Why |
|---|---|---|
| People you contact from the burner | **The burner number**, plus anything you send | Calls and texts show the line they came from. |
| Your main contacts | **Nothing**, on a separate iPhone | The burner never touches your main account. With Dual SIM, a slip in the number picker can expose it. |
| The carrier | **Your account details and usage** | You gave them a name, email, ZIP code and payment method to sign up. |
| Apple | **The account information you entered** | Email, phone number and any payment method on the new Apple Account. |
| Apps on the burner | **What you allow** | Location, contacts, photos and tracking are all permission-based. |
| Wi-Fi networks you join | **A per-network address** | Private Wi-Fi Address makes it harder to link your activity across networks. |
| Anyone who picks up the burner | **Everything on it**, if they know the passcode | Set a strong passcode, as on your main phone. |

## Keep what's on the burner from leaking back

Separation fails in small ways. Don't restore your main iPhone's backup onto the burner, don't AirDrop between the two, and don't sign in to the same social or email accounts on both. Photos taken on the burner can carry location data, so [remove location from photos](/blog/remove-location-from-photos-iphone) before you post or send them, and use [disappearing messages](/blog/disappearing-messages-iphone) where a conversation shouldn't stay around.

On your main iPhone, the opposite applies: photos you've shared with a new contact, such as listing photos or ID scans for a rental, don't need to sit in your camera roll forever. VaultForYou, the iPhone vault app we make, keeps files you choose outside the Photos library in a vault opened only by a pattern you draw. Files are encrypted on your iPhone, and no account is needed. It doesn't replace a second number; it keeps what you've already collected out of sight.

## When you're done with the burner

Dropping a burner is quick. On your main iPhone, go to **Settings -> Cellular**, tap the burner plan and tap **Delete Plan**. On a separate iPhone, sign out, erase the phone and choose to erase the eSIM too; our guide to [wiping an iPhone before selling it](/blog/wipe-iphone-before-trade-in) has the full steps.

One catch: Apple says deleting an eSIM doesn't cancel your cellular plan. To cancel it, contact the carrier.

## Frequently asked questions

### How to set up a burner phone?

Decide how much separation you need. For a second number only, add a prepaid eSIM line to your own iPhone with Dual SIM. For a separate device, erase a spare unlocked iPhone, create a new Apple Account during setup, activate a prepaid eSIM, and restrict location, tracking and notifications. Never restore your main iPhone's backup onto it.

### What is a burner eSIM?

It's an ordinary carrier eSIM, usually a prepaid plan, that you use as a separate number for a specific purpose. iPhone XS, XR and later support eSIM, and Apple says iPhone 13 and later can run two eSIMs at once. You activate it with a carrier QR code, app or eSIM Carrier Activation, and you can erase it when you're done.

### Can I have a burner number on my iPhone without a second phone?

Yes. Dual SIM lets one iPhone hold two active numbers, for example a physical SIM and an eSIM, or two eSIMs on iPhone 13 and later. Label the lines, pick a default number, and choose which line each contact uses. Both numbers live on the same phone and the same Apple Account, so it's less separate than a second iPhone.

### Does a burner number make me anonymous?

No. A second number keeps your main number away from people you deal with, but it isn't anonymity. Carriers ask for details such as your name, email, ZIP code and payment method when you sign up, and some places require an in-person ID check to activate an eSIM. Apps also collect whatever data you allow them.

### Is setting up a burner phone legal?

Owning a second phone or prepaid number is ordinary: people use them for work, dating, selling online and travel. A burner doesn't change what's legal, though. Rules on prepaid activation and ID checks vary by country, and using any phone to harass, threaten or defraud people is illegal regardless of the number. If you're unsure about your situation, check local rules.

### Do I need a new Apple Account for a burner iPhone?

If you want a separate phone, yes. Signing a burner in to your main Apple Account would sync your photos, messages, contacts and more onto it, defeating the purpose. Create a free Apple Account during setup with an email used only for that phone. For a second line on your own iPhone, you keep your existing account.

### Can I use iMessage with a burner number?

Yes. On a separate iPhone with its own Apple Account, iMessage uses that phone's number and account. With Dual SIM on your main iPhone, you choose which numbers iMessage and FaceTime use, and you can switch the number at the top of a conversation. Check Settings -> Apps -> Messages -> Send & Receive so new conversations start from the number you intend.

## Bottom line

A burner iPhone is a second number plus as little shared data as possible. For most people, a prepaid eSIM line on their own iPhone is enough; for real separation, use a spare unlocked iPhone with its own Apple Account. Tighten location, tracking and Wi-Fi settings, keep it away from your main account, and remember the limits: it hides your real number from people, not your identity from your carrier or the law.
