what is cb messages on samsung

CB messages on Samsung phones refer to Cell Broadcast messages , a special type of SMS‑style alert sent to many users in a specific area at once.

What “CB messages” means

  • CB stands for “Cell Broadcast” , a standardized feature built into GSM/3G/4G/5G networks that lets authorities or networks push the same short message to all phones in a given cell area.
  • On Samsung devices, these show up as “CB SMS” or “CB messages” in your Messaging app, often labeled with things like “EMERGENCY ALERT,” “WEATHER WARNING,” or “PRESIDENTIAL ALERT,” depending on your country.

What kind of messages you see

  • Emergency alerts : Government‑issued warnings for severe weather, natural disasters, terrorist threats, or other public‑safety events.
  • Public‑service alerts : Special traffic, safety, or civic notices (for example, in some countries, these are used for nationwide warning channels).

Unlike regular texts, CB messages are one‑way broadcasts and cannot be replied to.

Why you might be getting them

  • Location‑based broadcasting : If you’re in a cell area where an alert is active, your Samsung phone will receive it automatically as long as the CB feature is enabled.
  • Carrier or government policy : Some countries or networks require Cell Broadcast for emergency‑warning systems, so these alerts appear even if you didn’t manually subscribe.

How to manage or turn off CB messages on Samsung

On most Samsung phones, you can tweak or disable CB inside the default Samsung Messages app :

  1. Open Samsung Messages.
  2. Tap More (three dots) → Settings → Advanced or “More settings”.
  3. Look for “Cell Broadcast” / “CB messages” / “Emergency alerts” or similar.
  4. Toggle off “CB activation” or deselect unwanted categories (e.g., test alerts or certain warning types).

Exact wording varies by model and Android/One UI version, but the path is usually under Messages → Settings → Advanced / Emergency alerts.

Should you keep CB messages on?

  • Keep it on if : You want immediate, reliable emergency warnings (especially useful when traveling or in regions prone to severe weather or disasters).
  • Turn it off if : You find the alerts too frequent or annoying, and you rely on other channels (TV, apps, radio) for alerts.
