Tool boosts interoperability of eSIM, iSIM services
The Trusted Connectivity Alliance (TCA) has released a free tool to boost the interoperable deployment of SIM-based value-added services.
The TCALoader tool enables mobile operators and application developers to download, install and manage applications on the UICC / eUICC to test interoperability across different deployments. This supports increasing industry demand for the delivery of various services through eSIM and iSIM technology.
The wizard-based tool has been extensively tested against TCA member implementations which collectively represent the majority of the global market. This can significantly reduce the complexity of launching new services.

- First remote provisioning of iSIMs
- 5G and iSIM drive for IoT says report
“TCA has a proven record over decades promoting interoperability across the SIM ecosystem,” comments Bertrand Moussel, Chair of the TCA Board. “Developing and releasing the TCALoader as a publicly available tool reflects our organisation’s continued commitment to consistency and reliability. This is increasingly crucial as eSIM adoption builds and demand grows to leverage its advanced security and flexibility to host multiple applications, unlocking new opportunities for consumers, enterprises and industry.”
The TCALoader is an evolution of the CAT Loader tool first released by SIMalliance in 2007 (which became the TCA in 2020) and has been widely used by mobile operators and application developers to test and implement new services. The TCALoader introduces enhanced features to support different SIM form factors such as eSIM and integrated iSIM.
The tool has support for 3GPP Release 15 (5G) and the GlobalPlatform Card Specification Version 2.3, including HTTPs protocol and SCP03 as well as support for SCP02, CAT-TP and SMS protocols to maintain backwards compatibility.
There is Java Card application compilation and loading of applications based on the latest ETSI and 3GPP Java Card APIs as well as application and security domain auditing and management of secure element services.
TCA members include Giesecke+Devrient Mobile Security Germany GmBH, IDEMIA, Kigen, Linxens, NXP Semiconductors, Oasis Smart SIM, Qualcomm, STMicroelectronics and Thales.
The tool is available to download from the TCA website.
