Here’s what you need to know: That voicemail from your mom isn’t stored on your phone. It lives on your carrier’s server, and your carrier treats it like leftovers in the office fridge.

 The clock is already running

• AT&T: Basic voicemail keeps messages 14 days. Visual voicemail, 30.

• T-Mobile: 14 to 30 days, and once it’s deleted, their own support page says it “cannot be retrieved.”

• Verizon: Doesn’t publish an exact number, but their FAQ flat out says they’re not liable for deleted messages, “even if you saved them.”

• Consumer Cellular: Doesn’t publish a countdown. But their support is 100% U.S.-based, and they’ll walk you through saving a message step by step. Dial 611 from your phone, or call 1-888-345-5509. Do it before you need it, not after. Full disclosure: Consumer Cellular is a sponsor of my national radio show.*

 Save it forever (takes one minute)

I tested the steps below. Yours might be different, depending on your phone’s make, model and operating system. 

1. iPhone: Open Phone > Voicemail. Tap the message, then tap the Share button (the box with the arrow). Choose Save to Files, or tap More, then pick iCloud Drive or Google Drive. Done. It’s now an audio file you own.

2. Android: Open the Phone app > Voicemail. Tap the message to expand it, hit the Share icon and save it to Google Drive. It exports as an MP3.

3. Samsung: In Visual Voicemail, click and hold the message you want to save, tap Archive. FYI, archiving removes it from the server, so move that file somewhere safe right away.

4. Old-school or landline voicemail: Play it on speaker and record it with another device. Nobody’s judging. The recording is the point.

Pro tip: If you’re ever closing a loved one’s account, save the voicemails before you call the carrier.
