Embedded SIM (MFF4)

Description

MFF4 embedded SIMs deliver the same global cellular connectivity as MFF2 in an ultra-compact, soldered package. At just 2 × 2 mm, MFF4 is the smallest discrete eUICC form factor available, freeing up valuable PCB space for sensors, batteries and radios. It is the perfect choice for size-constrained IoT devices such as wearables, asset trackers, e-bikes and compact gateways, including devices that move between cities and countries or are deployed in remote environments.

Features

• Management of your embedded SIM via a cloud-based self-service platform.

• Support of Monogoto Toolkit (MTK). This is a feature to manage multiple IMSI profiles for enhanced connectivity and roaming optimization for a SIM.

• Monogoto secure IoT SIM works on 550+ cellular networks in 180 countries offering all network technologies. You can check our coverage by following this link.

• With the use of API, integrate 3rd party cloud applications and automate processes across your organization.

• Cloud-based private network with hybrid local-breakout. Radio and CPE agnostic solution supports CBRS and any band.

Embedded MFF4 SIM in functions

MFF4 packaging

MFF4 uses the 8-pin no-leads USON-8-6 package (2 × 2 mm). Full mechanical drawings and package dimensions are available on the manufacturer's page: Infineon PG-USON-8-6.

What is ICCID and where to find it?

ICCID stands for Integrated Circuit Card ID. This is a globally unique identification number for the SIM itself. ICCID number consists of 19 or 20 digits and is printed on the back of the embedded SIM. You can read more about this in our published article following this link.

Checking physical embedded SIM

ICCID on Embedded Monogoto SIM can be found on the embedded SIM chip itself.

Using AT commands

If your device supports the use of AT commands, then you can also check the ICCID by using an AT command.

Device Manufacturer	AT Command
U-blox	AT+CCID
SIMCom	AT+CCID
Nordic Semiconductor	AT%XICCID
Telit	AT#CCID
Quectel	AT+QCCID
Cinterion	AT+CCID
Murata	AT%CCID

Please note that the mentioned AT Commands may differ based on the used device model, even when using the same device manufacturer, so it is always a good idea to check the device manual to see what exact command you should use.
