What is OTA?

Over-the-air (OTA) in SMS refers to a type of SMS messaging that is sent and received wirelessly over a cellular network, rather than over a dedicated SMS gateway. OTA messages are sent directly to a mobile device, eliminating the need for manual intervention. 

Over-the-air (OTA) in SMS allows messages to be delivered quickly and efficiently to a wide range of users. As the messages are sent directly to the mobile device, they are not subject to delays associated with traditional SMS gateways. 

Furthermore, OTA messages are more secure than traditional SMS messaging, as they are not vulnerable to interception or manipulation by third parties. Additionally, OTA messages can be used to reach users who may not have access to traditional SMS gateways, such as those living in remote areas. 

OTA messages are also more cost effective than traditional SMS messaging due to their direct delivery method.

How does it work?

Over-the-air (OTA) in SMS works by sending a message directly from the sender’s device to the recipient’s device via a cellular network. The message is then delivered to the recipient’s device, usually within seconds. The message is encrypted, meaning it can only be read by the intended recipient. Once the message is received, the recipient can either read it immediately or save it for later. OTA messages are also stored on the sender’s device in case the recipient does not immediately read them.

What is it used for?

This type of SMS message is frequently used by Mobile Operators to provide or modify core network settings on your handset. These messages are used to optimize configuration settings e.g. SMS Service Center, Web settings, or to provide new services such as MMS.
