Single-use phone number designed for situations where you need to provide a contact number but wish to avoid giving out your permanent personal one. Think of it as a burner phone number, but without the need for a separate physical device or SIM card. These numbers are typically short-lived, ranging from a few minutes to a few days or weeks, depending on the service and the user’s needs. They are primarily used for receiving calls or SMS messages, particularly for verification codes or one-off communications.
SIM (Embd SIM) and iSIM (Integrat SIM)
These technologies are becoming increasingly japan phone number list prevalent in IoT. Instead of a physical! removable SIM! the SIM functionality is embd directly into the device’s hardware (eSIM) or even integrat into the device’s main chipset (iSIM). This offers greater flexibility! remote provisioning (over-the-air activation and switching of network profiles)! and increas durability for devices deploy in harsh environments. While an eSIM still has an associat identity and potentially an MSISDN! its primary purpose is seamless data connectivity and remote management.
LPWAN (Low-Power Wide-Area Networks)
Technologies like NB-IoT (Narrowband IoT) and LTE-M (Long-Term Evolution for Machines) are cellular standards optimiz for low-power! low-data- india number list rate IoT applications (e.g.! smart utility meters! environmental sensors). Devices using these technologies communicate over cellular networks but are design for extreme battery longevity! often sending handle objections gracefully small packets of data infrequently. They operate using cellular modules with associat identifiers! but typically not for voice calls.
