Our experts have dug deep into this concept and generated a comprehensive guide outlining every single aspect of the Cell Broadcast you need to know. In addition, the guide also contains a step-by-step guide to enable and disable these messages on Android phones. So, shall we begin?

Cell Broadcast – A Complete Introduction

First thing first!! Before we move on to the step-by-step guide to enable/ disable the cell broadcast, let’s first highlight the base factor, CB, and what’s it all about.

Cell Broadcast, formerly known as Short Message Service – Cell Broadcast (SMS-CB), is a sort of SMS message you can send to multiple users living in a given area. This service is used as a form of an emergency broadcast about missing children, severe weather, terrorist activity, or anything faulty.

CB is a part of the GSM standard set by the ETSI GSM Committee and is referred to as a helpful broadcast medium. It is way more trustworthy than other emergency alerts and will work even when cellphone networks crash owing to getting overloaded in emergencies.

These messages are included in all bandwidths, including 2G, 3G, 4G LTE, and 5G standards. Unlike short message service – Point to Point, CBs is a one-to-many geo-fenced and geo-targeted service. It was first demonstrated in 1997 in Paris and has been widely deployed since 2008 by major Asian, Canadian, European, US, and South American network operators.

The modern-gen cell broadcast message can be sent to a whole mobile network of around 1,000,000 cells in less than 10 seconds. Amazing, isn’t it?  However, you must know that CB is a non-confirmed push service, which means that the sender doesn’t know who has actually started the thread, thus allowing for services based on anonymity.

The CB message parameters contain the broadcasting schedule. If the start time is left open, the CBS system will assume an immediate start, and if the end time is left open, the cell broadcast message will be repeated indefinitely. The CB message page is composed of 82 octets and can encode 93 characters.
