Soracom Air

Soracom Air for Cellular is a network connectivity solution that enables device connectivity to public and private network services, as well as cloud services, using ubiquitous 2G, 3G, and 4G/LTE cellular networks.

Air for Cellular allows you to utilize robust cellular networks for IoT applications where signal strength is an important factor, and where traditional wireless communications (such as Wifi or Bluetooth) are insufficient.

Unlike typical 2G, 3G, and 4G/LTE IoT connectivity services, Soracom works with mobile network operators all over the world to provide global coverage, all with a single SIM card or Embedded SIM (eSIM). In addition, the Soracom platform provides tight integration between mobile network operator infrastructure and cloud services, to simplify IoT application development and help overcome common challenges with integration, security, and scale.


Soracom Air Features

Integrating Soracom Air for Cellular with your IoT application begins with a Soracom Air IoT SIM module (SIM card or Embedded SIM). Much like the SIM cards you receive from mobile network operators, an IoT SIM module authorizes your device to connect to cellular networks and establish data connections.

By simply inserting or integrating an IoT SIM module into your device, your device automatically gains global cellular data coverage, and is able to start sending and receiving data.

Soracom Air Architecture

In addition to a basic data connection, the Soracom platform gives you visibility into your Air for Cellular device's data usage, session status, cell location, and more. Soracom's platform and network services also help simplify the process of collecting, forwarding, or processing data, as well as implementing various security methods according to your IoT application requirements.

Unlike other connectivity solutions, Soracom's platform infrastructure gives you the power to integrate your Air for Cellular devices directly with private or cloud-based network services, such as AWS and Azure. While a typical cellular device may require exposing a private server to the Internet or configuring firewall exceptions in order for your devices to access the server, Soracom provides multiple network services that connect cellular devices directly to private networks, with transmitted data never traversing the open Internet.


Each Soracom SIM is composed of several nested components, each of which play a different role when establishing cellular network connectivity. While some terms may be used interchangeably, the component that you interact with may change depending on context, such as using an ICCID number when registering a SIM card, or identifying which device is connected by its IMSI number.

Soracom uses the following standard telecommunications terminology to identify the different SIM components:

Purchasing IoT SIMs

IoT SIMs can be purchased directly from Soracom via the User Console, or from select Amazon stores.

From Soracom

When purchasing a large number of IoT SIMs for your IoT application, we recommend purchasing directly from Soracom using the User Console. By doing so, the SIMs in your order will be pre-registered to your Soracom account. This allows you to easily register the SIMs to your Soracom account once you receive them without the need to manually register each SIM individually.

All IoT SIMs are available for purchase from the User Console.

In addition to simplifying the registration process, purchasing SIMs directly from Soracom also allows you to customize the initial Group, Speed Class, and Tags settings that will be applied to all SIMs in the order upon registration. This is especially useful if you are scaling up your IoT application and want to quickly apply the same settings to your new SIMs.

When customizing initial settings, the same settings will be applied to all SIMs in the order on a per-subscription basis. For example, if you purchase 100 IoT SIMs, the same initial Group, Speed Class, and Tags settings you choose will be applied to all 100 SIMs upon registration. However, while you cannot divide the SIMs in order to apply different initial settings, you can still modify these settings on each SIM individually after registration is complete.

In order to apply different initial Group, Speed Class, or Tags settings, you must place separate orders and configure the initial settings for each order separately.

For more information on customizing initial settings, refer to the Registration: Registering IoT SIMs from an Order documentation.

From Amazon

For small IoT applications or when developing proof-of-concepts, purchasing an IoT SIM from Amazon may be faster and cheaper. IoT SIMs purchased from Amazon stores still require a Soracom account. Additionally, such SIMs must be manually registered to your Soracom account, one at a time. For more information on manually registering SIMs, refer to the Registration documentation.

Certain IoT SIMs in SIM card form factor are available from Amazon stores. Embedded SIMs (eSIMs) are not available on Amazon stores.
