Telnyx is pleased to unveil the release of our IoT SIM card v4. This update signifies our commitment to continuous improvement and our dedication to leveraging the best roaming agreements available, ensuring our customers benefit from unparalleled connectivity and service reliability.
Upgraded operating system: Following our SIM vendor's latest recommendations, the new SIM card version features an enhanced OS for optimal performance and security.
Enhanced HTTPS OTA applet functionality: We've upgraded the OTA update functionality, enabling more timely and secure OTA updates for your devices.
GID1 & GID2 files for seamless APN configuration: We’ve added GID1 and GID2 files (ETSI 4.2.10-11) to support the automatic population of Telnyx MVNO details in devices. This means that APNs for data connections are set automatically in newer versions of major operating systems, including Android, iOS, and Windows.
NCP-IP file addition: To further simplify connectivity, the NCP-IP file *(ETSI 4.2.90) *has been added to assist devices in selecting the correct APN (Telnyx APN) for data connections. Please note that the availability of this feature is device-dependent.
Updated IMSI account selection: v4 SIM cards benefit from an updated multi-IMSI solution that continues to expand our coverage and increase our multi-carrier redundancy.
IMSI fallback capability: The v4 cards are optimized to leverage our multi-IMSI technology by automatically switching to another IMSI if connectivity via the active IMSI is lost, giving an extra layer of redundancy and reliability. This functionality will be disabled by default and can be enabled via OTA. Note: Some devices may lose the existing APN settings when the IMSI used for connectivity services is changed.
Environmentally friendly design: In line with our ongoing commitment to improved sustainability, the new SIM cards are a triple-half design, using less plastic to reduce environmental impact.
IoT devices equipped with new Telnyx SIM v4 cards will automatically enjoy enhanced performance, more reliable connectivity, and seamless integration with the latest device operating systems.
Plus, with our focus on environmental sustainability, you can feel good about choosing Telnyx.
Stay tuned for more information on how to access these new SIM cards and take full advantage of the improved features and connectivity.
