CMU200/CMW500 Nano Test SIM Cards: Pre-Configured or Custom IMSI/Ki/OPc from HKCARD

In the high-stakes environment of mobile phone manufacturing and RF testing, every component matters. Yet there is one piece that rarely gets the attention it deserves until something goes wrong: the test SIM card. If you have ever lost an afternoon debugging a failed call setup on a CMW500 only to trace it back to a faulty or misconfigured SIM, you already know why this guide exists. At HKCARD ELECTRONICS CO., LIMITED, we design and manufacture Nano Test SIM Cards specifically to eliminate that headache — delivering robust, pre‑configured authentication for Rohde & Schwarz CMU200 and CMW500 platforms right out of the box.

Why the Right Test SIM Card Is Critical for Your CMU200 and CMW500

Engineers naturally focus on the vector signal generator, the DUT, RF cables, and shielding. The SIM sits in the tray, silently expected to authenticate perfectly across thousands of cycles, over every generation of network simulation — 2G, 3G, and 4G — without a single failure. In high‑volume factories across China, Vietnam, India, and Mexico, where hundreds of handsets flow through test bays daily, a SIM that just works is not a luxury; it is a production‑line requirement.

HKCARD Nano Test SIM Cards are built for exactly that expectation. Pre‑matched to the default network simulation profiles of both the R&S CMU200 and CMW500, they eliminate authentication troubleshooting so your team can focus on what really matters: device performance, throughput, and yield.

 Product Overview – HKCARD Nano Test SIM Card at a Glance

The card arrives ready to insert into any CMU200 or CMW500 test station. No parameter adjustment, no manual key entry, no wasted time. The authentication handshake completes cleanly on the first attempt, every time.

 Full Network and Test Coverage – 2G, 3G, 4G All on One Card

2G GSM Testing

Despite the global shift toward LTE, GSM testing remains mandatory for regulatory and roaming compliance — especially in markets across Africa, Southeast Asia, and Eastern Europe where legacy infrastructure still carries traffic. Our Nano Test SIM supports:

• GSM 850 / 900 / 1800 / 1900 MHz
• CS voice call setup (MO/MT) on CMU200 and CMW500
• GPRS/EDGE data bearer tests
• SMS functional verification

3G WCDMA / HSPA Testing

Most 4G handsets still require 3G fallback capability. Production lines need a SIM that authenticates seamlessly across both 3G and 4G without profile switching. Our card handles:

• WCDMA Bands I, II, IV, V, VIII and more
• HSPA / HSPA+ data bearer setup
• CS voice over WCDMA
• Inter‑RAT handover scenarios (3G ↔ 4G)
• IMS registration for VoLTE fallback testing

4G LTE Testing

The bulk of modern test time is spent on LTE. The SIM must support EPS‑AKA authentication without a hitch. Our card delivers:

• LTE FDD and TDD mode operation
• VoLTE / IMS registration and call setup
• Data bearer establishment and throughput measurement
• Inter‑frequency and inter‑RAT handover
• Carrier aggregation test scenarios (with appropriate CMW500 licensing)

For labs that need to push boundaries with custom IMSI, Ki, and OPc values, HKCARD offers a fully configurable variant — we program the parameters before shipping, so the cards arrive precisely matched to your private network or custom simulation profile.

The Nano Form Factor – Engineered for Factory‑Floor Reliability

Modern smartphones almost universally use the Nano SIM (4FF) form factor. Trying to use an adapter or a cut‑down card on a high‑cycle automated test line introduces mechanical risk: tray damage, intermittent contact, and premature wear. HKCARD’s Nano Test SIM Cards are:

• Native 4FF – no adapters, no cutting, no risk
• Dimensionally precise – fits every standard SIM tray without force
• Gold contact plated – stable resistance values across thousands of insertions
• Reinforced substrate – resistant to cracking and delamination in robotic handling

For factories employing robotic SIM insertion on fully automated lines, we offer high‑durability variants specifically rated for extreme insertion‑cycle demands. Contact us directly to discuss your production volume and we will recommend the right card configuration.

 Who Depends on HKCARD Nano Test SIM Cards – and How to Order

📱 Mobile Phone Factories

From flagship smartphone assembly lines to mid‑range handset production, factories across China, Vietnam, India, and Mexico use our test SIMs daily. They trust the cards to be consistent, durable, and maintenance‑free.

🔬 RF & Protocol Labs

When you need to reproduce a field failure or validate a pre‑production firmware build, flexibility matters. Our cards support the full CMW500 parameter space and can be supplied with custom security credentials to match your specific lab network.

📋 Device Certification Centers

Carrier acceptance testing (GCF, PTCRB, and operator‑specific programs) demands repeatability. HKCARD supplies known‑good test SIMs to certification houses worldwide — ensuring that authentication is never the variable.

🛠️ After‑Sales Service

Repair centers use CMU200 and CMW500 benches for post‑repair verification. Our durable Nano Test SIM survives the handling of a busy service center, delivering consistent authentication run after run.

Ordering Options at a Glance

• Custom Profiles: Specify your IMSI, Ki, OPc and any special file structure requirements. We program before shipping.
• Bulk Factory Orders: Competitive pricing and guaranteed batch‑to‑batch consistency.
• Evaluation Quantities: Small batches available for compatibility testing before you commit to a full production order.

Frequently Asked Questions

Will your Nano Test SIM work on my existing CMU200 without any changes?
Yes. The standard configuration is pre‑matched to the default internal network simulation parameters of the CMU200.

Can the same card be used on both CMU200 and CMW500?
Absolutely. The authentication parameters are compatible with both platforms. Many customers use the same SKU across mixed test environments.

Do you support custom Ki and OPc values?
Yes. Send us your target values and we will pre‑configure the cards accordingly.

How many insertion cycles can the card withstand?
Standard cards are rated for several thousand cycles. For robotic lines, ask about our extended‑durability variant.

Is LTE band support limited by the SIM card?
No. Band support is determined by the CMW500 license and the DUT. Our SIM authenticates across all licensed bands.
