With internet evolving at a breakneck pace, the elderly are becoming increasingly unfamiliar with mobile phones. Many of them are unable to use E-maps, GPS navigation, and ride-hailing apps, even smartphones, which puts them at a competitive disadvantage of being difficult to hail a cab on the roadside for a long time. The “Digital Travel Dilemma” traps the lifestyle and restricts the quality of life and the consumption level of the elderly. Due to the difficulty in locating users and the high costs and low efficiency of human customer service or audio order listening by taxi drivers, the current use and promotion of ride-hailing service hot line are very challenging. TeleNavi is the world’s first "Voice-Only Location and Navigation Tech and Service ", designed for elderly users, international travelers, and those in low-network-coverage areas, delivering seamless travel assistance through voice positioning. Leveraging TMF Open API, GSMA Open Gateway API and AI LLM, TeleNavi enables voice-only positioning and ride-hailing services via phone calls, making travel more convenient and inclusive. No apps, no GPS, no 4/5G mobile data, no smart devices and no complicated steps, just a basic feature phone to make a simple phone call can solve it all.
