About Us
As Internet of Things (IoT) becomes increasingly popular, more and more devices, including open (SIM free) devices that uses cellular module, are expected to be connected to a carrier’s network.
To help promote such devices to a wider audience. To enable an ever easier connection to our network.
Bearing in mind the goals above, we provide all the necessary information to conduct our connectivity verification (IOT: Interoperability Testing) on this site.
- ※A part of this site requires member registration to be accessed.
- ※The information provided on this site does not guarantee the quality of a product and its functions. For questions regarding a product’s function and quality, please directly inquire to the manufacturer of the product.
Overview
- ①：Products that have passed IOT (IOT-verified products) are listed here
- ②：Products offered by KDDI are listed 「here」 (in japanese only)
- ③：Customers who wish to use IOT-verified modules are advised to read the Guideline for Embedding Communication Module～KDDI LTE Network Specification Outline and Legal Compliance～ available in our Member's Page
Connectivity Verification (IOT : Inter-Operability Testing)
IOT is a test to confirm the connection compatibility between a manufacturer’s product and KDDI’s network.
Test Outline
| 1 | Pre-IOT | Tests conducted using simulator |
| 2 | IOT-L (Lab Test) | Test(s) conducted in KDDI's lab (※1) |
| 3 | IOT-F (Field Test)(※2) | Test(s) conducted in KDDI's commercial network. (Parts of the test are conducted using simulator) |
- ※1: KDDI's lab is located in Tama, Tokyo.
- ※2: Technical Regulations Conformity Certification or Attestation of the Construction Design of Specified Radio Equipment is required to conduct field test.

Basic Requirement for Connection
To connect to our network, your product shall comply with 3GPP/RFC specifications and fulfill the following requirements.
| Category | Requirements | Remarks | |
|---|---|---|---|
| Frequency (E-UTRA band) |
LTE | 2.1GHz (B1) 800MHz (B18/B26) 1.8GHz (B3) 1.5GHz (B11) 700MHz (B28) 3.5GHz (B42) |
Emergency call uses SUPL2.0 protocol. LPWA (LTE-M) uses 800MHz (B18/26). LTE anchor for 5G uses B1 and B3. |
| 5G | FR1(n77) FR2(n257) |
Smart Watches cannot use 5G systems. | |
| Supported system | Data communication | LTE / 5G | UMTS/GSM is not supported, CDMA2000 is outside the scope of IOT. LPWA is supported only LTE-M. |
| Voice call | VoLTE | CS call (CDMA/UMTS/GSM) is not supported. VoLTE is not supported in LPWA (LTE-M). |
|
| SMS | SMS over IMS | Excluding LPWA (LTE-M) Smart Watches cannot use SMS service. |
|
| SMS over SGs | Only for LPWA (LTE-M) Smart Watches cannot use SMS service. |
||
| SIM Card | LTE / 5G | Nano SIM Card(4FF) | Voice call requires Nano SIM Card(4FF) |
Products that comply with standard specifications still may not connect correctly with our network. Therefore, we strongly recommend conducting connectivity verification to avoid problems.
