The simplest way to think of a pager is as a one way, text only mobile phone – a small device that can receive and display a short message.

To send that message needed a third party – the sender would call up a number assigned to that pager and either enter a message on their phone keypad or speak it to an operator, which would then enter it into the system and send it out to that particular pager.

Similarly to mobile phones there were multiple generations of the technology with different features. Some would only display a short numerical message such as a phone number for the owner to call from a payphone or other land line, others could display short messages in full text.

Generally they have been completely replaced by mobile phones on common use – a text message can pretty much do everything a page can and more. They are however still used in some situations where the simplicity of them is appreciated, or where the signal had been found to be more reliable than a mobile phones – in hospitals for example where the structures often cause issues with phone reception, and doctors want a simple, reliable way to be sent a message such as ‘go to room x’ without getting lost in the clutter of phone calls, messages and WhatsApp.
