“Insufficient balance. Please top up to continue using services.” – Do you remember entering codes like *#123# to check your mobile balance or manage your telecom services? These short, text-based messages are powered by Unstructured Supplementary Service Data (USSD), a communication protocol that allows mobile devices to interact with a network's computers.
When a user dials a USSD code on their phone, it sends a signal to the mobile network, which then processes the request and delivers an instant, text-based response. This simple yet powerful technology is still widely used across the globe, even as more advanced digital solutions are becoming the norm.
In Europe and North America, USSD was once the go-to solution for tasks such as balance checks, mobile top-ups, and account management. However, with the rise of smartphones and widespread internet access, telecom operators have shifted to feature-rich mobile apps. These apps provide an interactive and visually appealing user experience, allowing for advanced functionalities such as real-time notifications, data usage tracking, and seamless integration with other digital services.
The Evolution of USSD: A Brief History
USSD technology was first introduced in the 1990s during the rapid expansion of mobile networks. It evolved from the Unstructured Supplementary Service Indicator (USSI), which was part of the second-generation (2G) mobile networks. The primary purpose was to provide quick, text-based communication between users and network servers, enabling a variety of tasks such as balance inquiries, call forwarding, and mobile recharges.
Unlike SMS, which stores and forwards messages, USSD creates a real-time session between the user's mobile device and the network. This makes it a faster and more reliable method for two-way communication. Its speed and simplicity have ensured its continued relevance, particularly in regions where smartphones and high-speed internet connections are not yet widespread.
Global Relevance and Continued Importance of USSD
In Europe and North America, USSD has largely been replaced by mobile apps that provide enhanced user experiences with interactive interfaces and advanced features. However, in emerging markets across Africa, Asia, and Latin America, USSD remains an indispensable technology. It provides a vital link to mobile banking, financial services, and essential communication tools for users with limited access to the internet or advanced smartphones.
USSD in Financial Inclusion:
USSD is not just a tool for checking balances or buying prepaid credits; it is a game-changing technology that drives financial inclusion. By enabling basic banking transactions, such as money transfers, bill payments, and balance inquiries, USSD breaks down barriers that have historically excluded underserved populations from financial services. This capability is especially valuable in rural or remote areas, where traditional banking infrastructure is limited.
Bridging the Digital Divide:
USSD and SMS technologies are device-agnostic, meaning they work on any mobile phone model, from the most basic feature phones to the latest smartphones. This ensures universal accessibility, bridging the digital divide and enabling financial institutions to provide services to every customer segment.
The Future of USSD: Evolving with the Times
Despite the growing popularity of mobile apps and internet-based solutions, USSD is unlikely to disappear anytime soon. It still has a vast and loyal user base, especially in emerging markets where mobile penetration is high but smartphone adoption is relatively low. However, to stay relevant, USSD must continue to innovate and adapt to changing customer needs.
Integration and Innovation:
One potential future for USSD is to integrate with other platforms, such as mobile apps, web browsers, and chatbots. This hybrid approach would allow users to switch seamlessly between traditional USSD sessions and more interactive, internet-based experiences. Additionally, USSD can be combined with AI-driven services to provide intelligent customer interactions and personalised user journeys.
New Use Cases:
The versatility of USSD lends itself to innovative applications beyond traditional banking and telecom services. Potential use cases include:
- Identity verification for secure transactions.
- Digital receipts and loyalty programs for enhanced customer engagement.
- Social impact initiatives, such as healthcare reminders or educational notifications.
Unstructured Supplementary Service Data (USSD) has proven its resilience and adaptability over the years. From its inception in the 1990s to its continued relevance in global financial inclusion, USSD remains a critical communication tool that meets the needs of diverse markets.
While Europe and North America are shifting towards app-based solutions, emerging markets continue to rely on USSD for essential services. Its unique combination of speed, simplicity, and accessibility ensures that it will continue to play a significant role in the telecommunications landscape.
As technology evolves, so too will USSD, integrating with new platforms and leveraging innovative use cases to remain relevant. Whether enabling mobile banking in rural communities or supporting complex telecom operations, USSD is set to influence the future of global mobile communications for years to come.
This enduring technology is a testament to the power of innovation that meets real-world needs.
USSD for MVNOs
Mobile Virtual Network Operators (MVNOs) looking to provide USSD services to end users require a USSD Menu Browser Solution. For example, Lifecycle Software offers a comprehensive MVNO-in-a-Box solution that includes USSD options for mobile services. This USSD offering is integrated with WDS-SICAP, a company specialising in mobile connectivity.
