Start by checking Text Message Forwarding in your iPhone's Messages settings: it lists the Apple devices your iPhone currently sends text messages to, and you can switch off any device you no longer want included. Do this first because it is the most direct control over unwanted delivery. Treat Messages in iCloud and screen Mirroring as related but separate topics, and do not assume that turning forwarding off deletes every saved copy on another device.

Why the three settings can blur together
People often describe every message appearing on another Apple device as "forwarding." In practice, an iPhone can share text messages with selected Apple devices through Text Message Forwarding, and messages can also be shared through Messages in iCloud. Screen Mirroring is a display feature, not the same channel as message delivery, so observing a message on a shared Mac or iPad does not by itself tell you which mechanism produced it. Keep those observations separate before you change anything, because each has different controls and different limits. [Apple iPhone Guide: Set up Messages]
- Write down what you actually saw—which device, which kind of message, and whether the iPhone was nearby—before touching settings.
Start with Text Message Forwarding on your iPhone
On the iPhone that owns the phone number, open Messages settings and review the Text Message Forwarding screen. Apple's guidance says forwarding sends messages to the Apple devices you select and that you can review this from the owner's Messages settings. Switch off any listed device you do not want receiving your text messages. This is the most relevant protective action for this kind of delivery concern, and it works from your own signed-in account rather than anyone else's. [Apple iPhone Guide: Set up Messages]
| observation | limit | next step |
|---|---|---|
| A shared Mac shows iPhone text messages | Forwarding status alone does not explain every route a message can take | Review the Text Message Forwarding list on the iPhone first |
| A device you do not recognize appears | The label may be an old device or a duplicate name | Switch it off unless you can identify it as yours |
| Messages also appear through iCloud | Messages in iCloud is a separate sharing path | Check it separately; do not assume one switch covers both |
Check Messages in iCloud separately
Messages in iCloud can also share messages across your signed-in Apple devices. Follow the current options on your own device. If you have already reviewed Text Message Forwarding and still see messages syncing, look at your Apple account and Messages settings for iCloud-related options in your own account. Do not assume a single toggle governs both forwarding and iCloud syncing; they are distinct features with distinct descriptions. [Apple iPhone Guide: Set up Messages]
Review devices only inside your own account
Inspect the devices listed in your own Apple account and your own Messages settings rather than asking anyone else to report what their device shows. A device name in a list is an administrative label, not proof of who has used it, where it is, or what someone intended. It also is not a verdict about a relationship. Limit yourself to your signed-in devices and your own account controls; do not attempt to access another person's account, and do not treat a shared device's silence or a privacy setting as evidence of anything.
- Remove or switch off devices you do not recognize or no longer use, then re-check the list after a short wait.
What revoking does and does not do
Turning off forwarding or removing a device stops future delivery through that path. It does not establish that every message already saved on that device, in a backup, or in a screenshot has disappeared. Apple's forwarding guidance describes sending messages to selected devices and reviewing that selection; it does not promise retroactive deletion everywhere. So plan around two separate questions: stop new delivery, then decide, calmly, whether you need to address existing copies—without expecting settings changes to reach files you cannot see. [Apple iPhone Guide: Set up Messages]
- After revoking access, send a test message and confirm where it appears before concluding the change worked.
Keep the review proportionate
A forwarding review is a maintenance task, not an investigation. Repeat it when you change devices, share a household device, or notice messages appearing somewhere unexpected. If what you see suggests a compromised account rather than a delivery setting, treat that as a separate security matter and use the account-recovery paths offered by the platform rather than guessing at causes from a device list.
- Set a personal reminder to review the forwarding device list after any device change.
A couple more questions
Does turning off Text Message Forwarding delete messages already on the other device?
No. Switching off forwarding stops delivery through that path; it does not establish that messages already saved on another device, in a backup, or in a screenshot are removed. Treat stopping future delivery and addressing existing copies as separate steps.
Is Messages in iCloud the same as Text Message Forwarding?
They are distinct. Text Message Forwarding sends text messages to Apple devices you select, while Messages in iCloud is a separate syncing feature. Changing one does not necessarily change the other.
Can I review forwarding for someone else's iPhone?
Only within your own signed-in account and your own devices. This review is for your own iPhone's settings; it is not a way to audit another person's phone, and a device name in a list is not proof of identity, location, or intent.
If a device keeps showing messages after I switch things off, what should I do?
Confirm which path is delivering them—forwarding versus iCloud—by checking each setting separately, then retest. If messages persist unexpectedly and you suspect account compromise, use the platform's own account-security and recovery options rather than guessing from the device list.
