Auto Forward Texts: How to Set It Up

Auto-forwarding texts lets you automatically send incoming SMS or iMessage to another phone number, email, or device. You set it up in your phone’s settings or with a carrier feature, and after that, every new message arrives in both places without you doing anything. This guide covers the main ways to do it on iPhone and Android, what each method can and cannot do, and the privacy trade-offs to know about.

Formula

The calculator above is a simple helper: it estimates how many setup steps you will need based on the method you choose. The formula is:

Steps = 3 + (Method − 1) × 2

• Steps – approximate number of menu taps or settings changes (unit: steps)
• Method – 1 for iPhone, 2 for Android, 3 for carrier-based forwarding

This is not a physical law; it is a rough planning tool. The real number varies by phone model and OS version.

Worked Example

Using the defaults: Method = 1 (iPhone), Time = 5 minutes.

1. Plug in: Steps = 3 + (1 − 1) × 2 = 3 + 0 = 3
2. So on an iPhone you will touch roughly 3 settings screens to enable forwarding.

The calculator shows 3 steps, matching the example.

What “Auto Forward� Actually Means

People use “auto forward texts� for two different things:

• Forward to another device you own – e.g., getting your iPhone texts on your iPad or Mac, or your Android texts on a tablet.
• Forward to another person or number – e.g., a work phone that sends all personal texts to your personal number, or a parent monitoring a child’s phone.

Both are possible, but the setup and limits are different. The first is built into both major phone OSes; the second usually requires a carrier service or a third-party app.

iPhone: iMessage Forwarding and SMS Relay

On an iPhone, Apple’s built-in feature is called Text Message Forwarding. It works with iMessage and with regular SMS/MMS, as long as the other device is signed into the same Apple ID and is on Wi-Fi or cellular.

1. On your iPhone, go to Settings → Messages → Text Message Forwarding.
2. Turn on the toggle for each device (iPad, Mac, iPod touch) you want to receive texts.
3. On the other device, you may see a six-digit code appear. Enter it on the iPhone to confirm.

After that, all new texts arrive on both devices. Existing conversations do not sync backwards; only new messages forward. If you turn off the toggle, the other device stops receiving new texts but keeps the history it already has.

This only works when the iPhone is on and connected to the internet. If the iPhone is off or in airplane mode, the forwarded device will not get the message either, because the iPhone is the one doing the forwarding.

Android: Using Your Google Account or Manufacturer Tools

Android does not have one universal forwarding setting. The most common built-in method is Google Messages for web, which mirrors your texts to a browser on any computer.

1. Open Messages on your Android phone.
2. Tap the three-dot menu → Device pairing → QR code scanner.
3. Go to messages.google.com/web on your computer, scan the QR code, and your texts appear there.

This is not exactly forwarding – it is mirroring, and it only works while the phone and computer are online. Some manufacturers (Samsung, Xiaomi, etc.) also offer their own “Continue on other devices� or “Link to Windows� features that do a similar thing.

If you want to forward texts to a different phone number (not just another screen), Android has no native setting. You will need a carrier feature or a third-party app.

Carrier-Level Forwarding and Third-Party Apps

Mobile carriers in many countries offer call forwarding for voice calls, but SMS forwarding is less common. Some carriers provide it as a paid add-on, often marketed as “message forwardingâ€� or “SMS relay.â€� You usually activate it by dialing a code like **21*number# or through the carrier’s app/website. The exact code and availability vary by carrier and country, so check with your provider.

Third-party apps like MightyText, Pushbullet, or Join can forward SMS from Android to a computer or another phone. These apps typically require:

• An Android phone with the app installed and given SMS permission.
• A companion app or web dashboard on the receiving device.
• A data or Wi-Fi connection on both ends.

Free tiers usually limit how many messages you can forward per month, and they may show ads. Paid tiers remove limits. Privacy is a real concern: the app’s servers see your messages, so read their privacy policy before using one.

Common Problems and How to Fix Them

People often hit the same issues when setting up forwarding:

• Forwarded device does not get texts – Check that both devices are on the same Wi-Fi or have cellular data. On iPhone, verify that the Apple ID is the same on both devices and that “Text Message Forwardingâ€� is toggled on for the specific device.
• Verification code never appears – On iPhone, restart both devices and try again. On Android, make sure the phone and computer are on the same network, or try a different browser.
• Forwarding stops after a few days – Some Android apps lose background permission. Go to battery settings and allow the app to run in the background.
• MMS (picture messages) do not forward – On iPhone, MMS forwarding requires that “MMS Messagingâ€� is enabled in Settings → Messages. On Android, some apps only forward SMS, not MMS.
• Forwarded texts show the wrong sender – When forwarding to another number via carrier, the recipient sees the original sender’s number, not yours. This is normal; it is not a bug.

Privacy and Security Considerations

Auto-forwarding means your messages exist in more than one place. That has real consequences:

• Anyone with access to the forwarded device can read everything. If you forward to a work computer, your employer may see personal texts.
• Third-party apps see your messages. Even “end-to-end encryptedâ€� apps like WhatsApp do not forward SMS; the SMS themselves are not encrypted when sent over the cellular network.
• Carrier-level forwarding can be abused. If someone gains access to your carrier account, they could redirect your texts to their own number. Use strong, unique passwords on your carrier account.
• Two-factor authentication codes are texts too. If you forward them, the receiving device also gets the code. That can weaken account security if that device is not as protected as your phone.

If you are forwarding a child’s phone for parental monitoring, be aware that the child may notice and that some jurisdictions require consent from the child or the other party. This is a legal gray area, not just a technical one.

Alternatives to Auto-Forwarding

Sometimes auto-forwarding is not the best tool. Consider these alternatives:

• Cloud sync – Use an app like WhatsApp or Telegram on both devices; they sync messages across devices natively without forwarding.
• Email-to-SMS gateways – Some carriers let you send an email that arrives as a text. This is one-way (you can send to a phone, but the phone’s replies do not come back to your email easily).
• Manual forwarding – Simply copy-paste the text you want to share. It is slower but gives you full control over what is shared.
• Dual SIM or second line – If you need a separate number for work, a second SIM or eSIM keeps messages separate without forwarding.
• Number porting – If you are permanently switching numbers, port your old number to the new carrier so all texts arrive directly.

Each alternative has trade-offs in convenience, privacy, and cost. Auto-forwarding is best when you genuinely need to see every text on another device immediately, and you trust that device.

Frequently Asked Questions

Can I forward texts from my iPhone to an Android phone?

Not directly through Apple’s built-in feature. Text Message Forwarding only works between Apple devices signed into the same Apple ID. To get iPhone texts on an Android phone, you would need a third-party app that reads your iPhone’s notifications (which has limitations) or a carrier service that forwards SMS to any number. There is no clean, free, built-in way.

Does auto-forwarding work when my phone is off?

No. Both iPhone’s Text Message Forwarding and Android’s web mirroring require the phone to be on and connected to the internet. The phone receives the SMS first, then forwards it. If the phone is off, the message waits in the carrier’s system and is delivered when the phone turns back on – but it will not forward to the other device.

Will forwarding texts use extra data?

Yes, a tiny amount. SMS messages are a few hundred bytes, so even hundreds of texts use less than a megabyte. MMS (pictures and videos) use more, but still small compared to streaming. If you are on a limited data plan, the impact is negligible for typical text volume.

Can I forward texts to an email address?

Some carriers offer an email-to-SMS gateway that works in reverse (email becomes a text). For forwarding incoming texts to email, you would need a third-party app like MightyText or IFTTT. Apple does not have a built-in setting to email your texts automatically.

Is it legal to forward someone else’s texts without their knowledge?

In most places, intercepting or forwarding someone else’s messages without consent is illegal. This applies to spouses, parents, and employers. If you are forwarding a child’s phone, you generally need to be the account holder and inform the child. For employees, company policy may allow monitoring, but it must be disclosed. When in doubt, get written consent.
