If you've blocked someone's messages—or suspect you have—getting unblocked is usually a straightforward process. The exact steps depend on your device type and which messaging app or service you're using. This guide walks you through the main platforms and explains what happens when you unblock someone.
Message blocking prevents a specific contact from reaching you via text, call, or in-app messages. When you block someone, they typically can't see that you've read their messages, and they may not receive delivery confirmations. Depending on the platform, they might not even know they're blocked—or they might receive a notification.
Unblocking reverses this restriction, allowing the person to contact you again normally.
On iPhone, blocked contacts are managed through the Settings app or directly within the Messages and Phone apps.
Via Settings:
Via Messages or Phone app:
Once unblocked, the person can text or call you normally, though any messages sent while they were blocked won't be delivered retroactively.

Important: Messages they sent while blocked won't appear in your inbox retroactively. Many platforms don't preserve blocked messages, so you won't see a backlog of their attempts to reach you.
Your choice to unblock someone depends on your specific circumstances:
| Platform | Blocks SMS/Calls? | Blocks App Messages? | Retroactive Messages Visible? |
|---|---|---|---|
| iPhone (native) | Yes | Yes (iMessage) | No |
| Android (native) | Yes | App-dependent | No |
| No* | Yes | No | |
| Facebook Messenger | No* | Yes | No |
| No (routing to spam) | Effectively yes | Yes (in spam folder) |
*These apps don't block calls or SMS—only in-app communication.
If you've blocked someone due to harassment, threats, or safety concerns, unblocking may not be the right choice—regardless of technical ease. In those cases, consider speaking with a counselor, trusted advisor, or legal professional before reinstating contact.
Unblocking is reversible, so if you unblock someone and realize it was premature, you can block them again using the same steps.
