Frequently Asked Questions (FAQ)

Q1: What is a blank SIM card?
A: A blank SIM card (or empty SIM card) is a smart card that has not yet been programmed with subscriber data like IMSI or Ki. It is used by developers and operators to customize network credentials.

Q2: Can I change the IMSI on your SIM cards?
A: Yes, we offer Writable IMSI SIM Cards that allow you to rewrite the IMSI as needed for testing or roaming simulations.

Q3: Are your 5G SIM cards compatible with 3GPP standards?
A: Yes, our 5G USIM Cards are fully compliant with the 3GPP Release 16 standard, making them ideal for 5G Stand alone and NR testing.

Q4: Do you support Sysmocom-style setups?
A: Yes, we provide Sysmocom Compatible cards, including sysmoISIM-SJA5 and sysmoISIM-SJA2 compatible programmable SIM cards.

Q5: What is the difference between a dummy SIM and a blank SIM?
A: A dummy SIM card is a non-functional plastic piece used for physical testing. A blank SIM card is a functional, electronic smart card ready for programming.

Q6: Can I get custom branding for my MVNO?
A: Absolutely. We offer Blank White Label MVNO SIM Cards with full Custom Printing & Packaging in 2FF, 3FF, and 4FF formats.
