SORACOM Air for Cellular


SORACOM Air for Cellular ("Air Cellular”) is a service that provides Air SIM, a data communications SIM card intended specifically for IoT devices.
Air Cellular lets you change various settings, monitor traffic, and more through its web console (user console) or API, facilitating central management of your IoT devices.

Features of Air Cellular

LTE/3G Mobile Data
Air Cellular provides data communications services over LTE/3G networks in a broad service area globally, which is necessary for IoT.

Metered Use
Air Cellular's usage rate plan has been optimized for IoT devices. The base rate is 0.05 USD~ per card per day, with metered usage from 0.073 USD~ per 1MB of data traffic. Pay only for what you use.
Please see the price page for detail

Control Multiple SIM Cards from the User Console or API
With Air Cellular you can control the Air SIM cards of multiple IoT devices. Pause and resume communication, change the speed of communication, or monitor traffic through the user console or API.

Purchase 1, 1000, or More SIM Cards Right Away
You can purchase as many Air SIM cards as you need right now, whether you want 1, 1000, or even more.
You can purchase Air SIM viaamazon.comfrom 1 SIM card.


You can purchase a single Air SIM card for a small initial expense and start using it as soon as it arrives and there is absolutely no hassle in setting it up. Air SIM does not impose restrictions with contract periods, making it perfect for device manufacturers and hardware start-ups prototyping new ideas.

Air SIM Sizes

Air SIM Sizes
Air SIM cards are available in all three sizes normally used by IoT devices, nano, micro, and standard. Most modern smartphones now use nano-sized SIM card, but many IoT devices still require the standard size. Air SIM cards can be used with any IoT device.

Intricate Control of Data Communications Through the API

Manage the data communications of your IoT devices with Air Cellular. From the API or the user console accessible via web browser you can change data communication speed, start or suspend use of an Air SIM card, monitor data usage, obtain an Air SIM card's ID (ICCID: Integrated Circuit Card ID, IMSI: International Mobile Subscriber Identity), and communication module IMEI (International Mobile Equipment Identity), and more.
This allows you to collectively configure the Air SIM cards of multiple IoT devices in remote locations.

The API can be called from IoT devices equipped with Air SIM cards or from other servers online.
You can use the API to set controls on data communication in order to lower data costs. You can increase data speed at night when you want your devices to send and receive data and pause data communication during the day.
In addition, by obtaining devices' ICCID, IMSI and IMEI codes, you can manage all your devices that use Air SIM cards.

Please refer to theDeveloper Sitefor more information on the API.

Settings can also be configured manually through the user console.

Data Usage Monitoring

Air Cellular lets you check for yourself how much data is being transmitted by each of your devices with Air SIM cards via the user console (an administrative web application) or the API. From the user console, you can view charts displaying how much data each Air SIM card is using and download detailed information as CSV files.

You can also obtain the URL to download the detailed data when using the API. Usage fees can be kept from getting out of hand by using this traffic data to mechanically check that none of your devices are using more data than you expected or to lower transmission speeds when traffic is higher than you planned.

Data traffic values are updated approximately every 5 minutes.

IMEI Lock feature

You can only allow Air SIM communication with the specified IMEI (terminal identification number: International Mobile Equipment Identifier).
IMEI is a unique identification number given to the 3G / LTE communication module. By using this function, it becomes possible to set that only the specific terminal can communicate. For example, you can use it if you are using an Air SIM in a remote IoT device is stolen, you can use it such as to prevent the use, use only a specific business terminal.
For details on how to set the IMEI lock function, please check thewebsite for developers.

CHAP authentication function

In common with AirSIM's APN setting, it is the following setting.

By using the CHAP authentication function, the customer can arbitrarily set Username and Password. With the CHAP authentication function, data sessions can only be established if Username, Password set on the terminal side matches the value set by the customer on SORACOM Air side.

For example, this function is useful when you can not identify the IMEI(*) or when you want to limit the connection to the group unit (the terminal with the same APN information), not the terminal unit lock like the IMEI lock.

(*) Depending on the Roaming Carrier (MNO) used, IMEI information may not be reported from the MNO to the SORACOM platform when a 3G / LTE session is created, in which case the IMEI is displayed as 0.

Configuring Custom DNS

Devices using Air SIM cards can be set up to use your own DNS servers.
This lets you control access from the device through DNS filtering and change the DNS to switch access points. The DNS can also be configured through the API to change when triggered by an event.
You can specify up to two DNS servers.
Please refer to theDeveloper Sitefor more information on the Custom DNS.

Metadata Service

Air's metadata service lets you obtain and update device Air SIM card information over HTTP. You can also change data speeds, add tags, and more if write access has been enable.
The API can be called with a simple code without needing to use the SDK even when calling the API on a single device. The device will also not need credentials.
Metadata service usage is configured in group units. Air SIM cards belonging to the authorized group will use the metadata service.
Please refer to theDeveloper Sitefor more information on the Metadata Service and its usage / use case.

* Send only to Air SIM owned by your account (OperatorID).

Send an SMS to a device using the API

You can send SMS using API. This makes it possible to send SMS to IoT devices using Air SIM from servers outside the mobile phone communication network, or to incorporate them into programs to automate transmission.
Since this function can only be sent to Air SIM owned by your account (OperatorID), you can prevent unauthorized access by SMS from outside and use secure SMS function.

Data size Message size 140 bytes
Unread message storage period maximum 25 hours
Messages that have passed the storage period are automatically deleted.
Resend Resend at intervals of tens of seconds to one hour.

SMS transmission / reception between devices

You can send and receive SMS from Air SIM held by your account (OperatorID) to Air SIM also held by your account.

Cloud collaboration using SMS

SMS transmission from the IoT device to the external server is also possible. The transmitted data can be transmitted and accumulated easily to your server by using in combination with data transfer support serviceSORACOM Beam, cloud resource adapterSORACOM Funneland data collection / storage serviceSORACOM Harvest.


You can use each service by sending SMS from the device using Air SIM to the following destination. (Group setting is required.)

For NAI, NPI, please use the following.


USSD stands for Unstructured Supplementary Service Data. On smartphones, you can use USSD to send data by dialing a special number in a phone application or the like. It can also be sent from the device using the AT command.
Using this function, you can transfer from device to Bev / Funnel via USSD or accumulate in Harvest.

When using USSD, it is not necessary to create a data communication session, and it is possible to send data quickly and easily. Also, data communication charges do not occur (USSD, Beam / Funnel / Harvest usage fee will be charged separately). Also, it is possible to return from the network side the response to the USSD sent by the device side.

It is a communication method suitable for the purpose of uploading a small amount of data from the IoT device at a relatively low frequency.

For more information please check website for developers.

SIM local info report

* This function is offered as Public Beta.
* SIM for global (plan 01s, plan 01s - Low Data Volume) is the target.

Use the Air SIM applet to get the device location information, IMSI, ICCID, IMEI, SIM battery information.
