Frequently Asked Questions

What is an IoT SIM card and how does it work?

An IoT SIM card is a specialised SIM designed to provide mobile connectivity for Internet of Things (IoT) devices. It enables equipment such as sensors, trackers, alarms, and smart meters to securely send and receive data over UK mobile networks—without relying on Wi-Fi or fixed broadband connections.

Why should I choose PurpleUC for IoT SIM solutions?

PurpleUC delivers IoT SIM cards with flexible data plans, nationwide UK network coverage, and enterprise-grade security features. Our SIMs are designed for maximum reliability and scalability, making them the perfect choice for businesses that need secure, always-on connectivity across a wide range of IoT deployments.

Can IoT SIM cards replace broadband or Wi-Fi connections?

Yes, in many cases. IoT SIMs can either replace or complement traditional broadband and Wi-Fi connections, especially in remote locations or mobile environments. They are ideal for critical systems that need failover connectivity to prevent downtime and maintain continuous operations.

What is the difference between single-network and multi-network IoT SIMs?

Single-network IoT SIMs connect exclusively to one UK mobile provider, making them suitable for areas with reliable, consistent coverage. Multi-network IoT SIMs automatically switch between major networks to maintain the strongest available signal, ensuring more resilient connectivity in locations with variable or patchy coverage.

What types of devices use IoT SIM cards?

IoT SIM cards power a wide variety of connected devices, including vehicle trackers, environmental sensors, security alarms, point-of-sale (POS) systems, smart meters, and industrial machinery. They are designed for both high-data and low-data applications, offering reliable performance across diverse use cases.
