In a private 4G/5G network, the SIM is small, but it controls everything: who can attach, how the device is authenticated, and which subscriber profile the core network sees. If the network belongs to you, the SIM profile should also be under your control—not locked to a generic template.
At HKCARD ELECTRONICS CO.,LIMITED, we provide programmable and customized SIM solutions for private LTE and 5G, including physical SIM, eSIM, and chip SIM (MFF2). Our focus is simple: stable profiles, correct provisioning data, and smooth deployment from lab to rollout.
What the SIM does in a private LTE/5G setup
A SIM securely stores the credentials and identifiers that your RAN and core network (EPC/5GC) use to:
- identify the device/user
- authenticate access
- establish a data session
In public networks, SIMs are often treated as “authentication only.” In private networks, many customers also use SIM capabilities to support stronger control, identity checks, or specialized applications (project-dependent).
What we can program and customize (typical items)
We can support SIMPersonalization based on your network design, including:
- Ki
- OP / OPc
- MCC/MNC (PLMN-ID)
- IMSI / SUPI / SUCI
- SPN / PNN
- and other operator- or project-specific parameters
If you already have a subscriber database format or provisioning process, we can align the SIM data output to match it.
Built for private networks of any size
Private networks don’t all look the same. Some customers need a few cards for a proof of concept, others need thousands for rollout. We support both, and we can keep profiles consistent across batches so your field teams don’t have to fight “same label, different behavior” problems.
Integration with EPC / subscriber management (optional workflow support)
For many customers, the hard part isn’t writing one SIM—it’s managing SIM data across provisioning, operations, and device onboarding.
We can support workflows where SIM profile data is prepared in a structured way so it can be transferred into your subscriber management system more smoothly. If you tell us which EPC/5GC you’re using, we’ll suggest a practical approach for profile preparation and delivery.
Available SIM types and form factors
We offer multiple options depending on your hardware:
- Physical SIM cards: 2FF / 3FF / 4FF
- Overlay SIM cards (project-dependent)
- eSIM
- Chip SIM (MFF2) for solder-down IoT / M2M devices
If you’re unsure which form factor you need, share the device model or SIM tray type and we’ll confirm.
How to start (the info we typically need)
To quote and prepare the right profile, we usually confirm:
- private 4G or 5G (SA/NSA)
- core network type (EPC/5GC vendor or stack)
- required identifiers (IMSI/SUPI ranges, ICCID rules if needed)
- authentication method (Ki, OP/OPc, algorithm requirements)
- form factor (2FF/3FF/4FF, eSIM, MFF2)
- quantity + whether you need printing/artwork
