Quick Overview

What Is a Programmable Blank SIM Card?

A programmable blank SIM card is a writable SIM module made for technical work rather than everyday retail use. It uses a rewritable EEPROM and a pre-installed COS, allowing developers and test teams to write supported data fields with a SIM card reader and software tools.

The HKCARD writable programmable blank SIM card – 2G/3G/4G compatible is suitable for mobile R&D, prototype devices, SIM application testing, and controlled lab work. It is not a pre-activated consumer SIM. Users need suitable programming knowledge, tools, and authorized test data.

Key Features of the HKCARD Programmable SIM Card 4G LTE

Fully Writable SIM Profile

The card allows users to configure supported fields such as IMSI, Ki, ICCID, OPC, and other data used in SIM testing. Access to these fields depends on the card, programming software, reader, and project requirements.

Multi-Network Compatibility

The HKCARD programmable blank SIM card works with GSM (2G) and UMTS (3G), and with some LTE (4G) networks. Actual 4G LTE access depends on carrier support, network parameters, device compatibility, and correct SIM configuration.

High Rewrite Durability

With a rated endurance of more than 100,000 write cycles, the card is suitable for repeated lab use, firmware testing, configuration changes, and long-term development work.

3-in-1 SIM Format

The card comes in a full-size SIM body with breakable cuts for standard, micro, and nano SIM sizes. This helps developers test across different devices, modules, and sockets without ordering multiple card sizes.

Developer-Friendly Design

The card is suitable for mobile communications R&D, SIM toolkit (STK) development, IoT prototyping, M2M communication testing, and network testing in authorized environments.

Pre-Installed COS

Each card includes a pre-installed COS. The flash area is used for the COS and user data, making the card suitable for SIM application development and test work.

Technical Specifications

Programming and Network Notes

The HKCARD programmable SIM card 4G LTE is made for custom telecom testing and development. Before using the card on a live network, confirm that you have permission to do so and that your SIM data is authorized by the network operator.

Network results can vary by country and carrier. For projects in Lebanon, Chile, Brazil, and South America, check the local network frequencies, carrier authentication rules, device compatibility, and SIM profile requirements. HKCARD can discuss technical details and product options with your team before ordering.

This card is not a “plug-and-play” consumer SIM. It requires a reader, software, and suitable programming knowledge. 4G LTE support should always be tested and confirmed for the exact carrier and device configuration in your project.

Common Use Cases

Telecom R&D and SIM Development

Engineers use programmable blank SIM cards to build and test SIM profiles, authentication parameters, STK functions, and device behavior in a controlled lab.

Mobile Device and Module Testing

The card can support development testing for phones, modules, modems, trackers, and IoT hardware that need configurable SIM data.

IoT Prototyping and M2M Communication

IoT and M2M teams can use writable SIM cards during prototype builds, network registration tests, roaming tests, and device validation.

Network Testing in Authorized Environments

Teams working with GSM, UMTS, or selected LTE networks can use the card for controlled test programs where network access is permitted.

QA, Repeat Testing, and Lab Work

With high rewrite endurance, the HKCARD programmable SIM card suits repeated writes, configuration changes, and batch testing.
