EMnify SIM Specification

Information regarding the barcodes printed on the new SIM cards

EMnify has launched a new SIM version, born out of a conscious effort to reduce plastic production. Any pluggable SIM shipped from July 2021 on (production date 09.06.2021 or newer) will come in the smaller frame format, cutting plastic production by 50 percent.

Please consider that The Barcode-128 for ICCID is smaller on the new SIM frame - 35mm x 4mm.

• It is printed vertically on the left-hand side of the frame.
• The barcode no longer embeds the six-digit PIN code, which is now printed below the EAN-13 BAR code.

If you still have older SIM versions in stock (Credit card size), please consider that they embed the PIN code when using an industrial reader (ICCID+PIN)

Storage guidelines

As long as the SIM cards are stored in their original packaging, you can store the SIM cards for long periods of time (up to 1 year) under these conditions:

• Temperature: 25°C +/- 5°C
• Humidity: 40% - 60%
