“German Real-World Testing—Localized APN Nodes: “10-Second Login, Millisecond Latency”
The three-day PMR Expo 2025 in Cologne, Germany, has successfully concluded. YCTEL made its debut with its international IoT SIM card, receiving unanimous recognition from attendees—distributors and brand manufacturers. On-site testing of the YCTEL Green Card 2.0 (network coverage across Europe and North America) with its European localized APN node demonstrated seamless compatibility with terminals from various participating brands. In network testing,
the device achieved initial network registration time in the 10-second range and intercom latency in the millisecond range, fully showcasing the importance of localized APN nodes, a feature YCTEL has consistently emphasized. A faster, more stable, and more professional international SIM card standard has emerged!
This new international IoT industry standard also signifies the end of the era of global roaming with a single SIM card! More professional, faster, and more stable localized nodes will increasingly become the primary choice for domestic IoT terminals going global!
“Core Chain Card” – The Six-Pulse Divine Sword that breaks through the physical boundaries of time and space!”
With the evolving technological trends of IoT cellular modules towards “two lows and one high”
—low power consumption, low cost, and high coverage — CAT-1/CAT-M1 cellular modules will become the mainstream modules for IoT terminals globally, both now and in the future . This places new demands on international IoT SIM cards, limiting the application of traditional plug-in and patch SIM technologies in future scenarios. Consequently, the “MESHSIM” technology—the “CoreLink SIM”—has emerged , offering wider coverage, over-the-air (OTA) network switching, and lower power consumption . At the German exhibition, we tested the network capabilities of the CoreLink SIM, and the test results received unanimous praise from all attendees!
