Unwanted texts from someone you know: a calm, step-by-step response plan

Spam is easy: block, report, move on. Unwanted texts from someone who actually knows you (an ex, a former coworker, a neighbour after a dispute, a buyer from a deal that fell through) are harder, because they already have your number and blocking feels like it might escalate things. Here is the plan I use and recommend to friends. It is boring on purpose: boring keeps you safe and keeps a clean record.

1. Send one clear message, then stop replying

If it is safe to do so, send a single, short, neutral message:

"Please stop contacting me. I won't be replying to further messages."

No explanations, no apologies, no arguing. One message gives you a timestamped point where you clearly asked them to stop, which matters later if you need to show a pattern. After that, every reply you send restarts the conversation, so don't.

If you feel unsafe, skip this step entirely and go straight to documenting and getting help.

2. Document before you block

Blocking on some phones hides or deletes the thread, so save it first:

• Screenshot each message with the sender and the date visible.
• Export the thread if your messaging app supports it, or back it up.
• Keep a simple log: date, time, what was said, how you felt or what it affected (missed work, changed your route home, and so on).

Store the copies somewhere other than the phone, such as an email to yourself or a cloud folder.

3. Block on every channel, not just SMS

People who ignore a "stop" message usually switch channels. Block or restrict them on SMS, WhatsApp, Telegram, Instagram, and email at the same time, and tighten who can see your profile details.

4. Close the gaps that let them find you again

Your number is often the key that links your accounts together. A short audit helps:

• Remove your number from public profiles, old marketplace listings, and group chats you've left.
• Turn off "find me by phone number" in social and messaging apps.
• Change passwords and turn on app-based two-factor authentication if they ever had access to your devices.

5. When you still have to send something

Sometimes you can't go fully silent: you need to tell a former landlord where to send a deposit, or confirm a final detail with someone from a sale. In those cases, send a one-way message that doesn't hand over your personal number again. On Android, Ghost lets you send an SMS without showing your real number. It is send-only: it does not give you a second number and you cannot receive replies or codes on it, which is exactly the point when you don't want a conversation to restart. It's free to download and uses in-app credits for sending.

6. Know when to escalate

Get outside help if the messages include threats, show up at your home or workplace, involve explicit images, or keep coming from new numbers after you've blocked them. Your saved screenshots and log are what police, a lawyer, HR, or a support organisation will ask for first.

Short version: one clear "stop", save everything, block everywhere, close the gaps, and only send one-way messages when you truly must. None of it requires confronting anyone, and all of it puts you back in control of your own number.
