📌  Q&A

🟢 What is the difference between 4G Nano+NFC Factory Sim Card 1.8v and 3.6v?

Answer:
The main difference is voltage compatibility.

  • 1.8v cards are typically used for low-power IoT or legacy hardware.
  • 3.6v versions are common in modern telecom smartphones.
  • 1.62v–5.5v provides broadest compatibility, ideal for large-scale, cross-market deployment.

🟢 What is sim swp and how does it work in NFC SIM cards?

Answer:
SIM SWP (Single Wire Protocol) connects the secure element in an NFC SIM directly to the smartphone’s NFC controller, enabling secure mobile payments, access control, and transit functions without a separate chip.

🟢 Can I order nfc white blank cards with my own design?

Answer:
Yes! We produce high-quality nfc white blank card batches with your logo, QR code, or personalization. It’s perfect for telecom operators, B2B launches, and custom branding. MOQ: 1,000 cards.

🟢 Do you offer developer-friendly test sim card kits?

Answer:
Absolutely. Our test sim card kits support comprehensive OTA testing, custom APNs, and are pre-configured with cryptographic profiles. Bulk developer packs are available worldwide.

🟢 How are NFC SIM cards different from regular SIMs?

Answer:
NFC SIM Cards have an embedded secure element that supports contactless services (payments, metro access, digital ID), unlike regular SIMs that only provide carrier connectivity.
