In the ever-evolving landscape of telecommunications, change is inevitable. As we march towards the future of connectivity, older technologies must make way for newer, more advanced ones. One such transition that is set to reshape the mobile network landscape is the impending shutdown of 3G services in 2024 by EE, one of the leading telecommunications providers in the UK. For users of roaming SIM cards, this development carries significant implications. In this blog post, we’ll delve into the background of 3G technology, understand why EE is bidding farewell to it, and guide our readers on what steps they should take to ensure seamless connectivity in a post-3G era.

The Evolution of Mobile Networks: A Brief Overview

1. 1G to 3G: The Rise of Mobile Data

The journey of mobile networks began with 1G, which facilitated basic voice calls. The subsequent iterations, 2G and 3G, introduced text messaging and mobile data capabilities, respectively. 3G, in particular, marked a significant milestone by enabling faster data transfer speeds, video calling, and mobile internet access.

2. 4G LTE: The Dawn of High-Speed Connectivity

The introduction of 4G LTE (Long-Term Evolution) further revolutionized mobile communication, providing faster data rates, lower latency, and enhanced overall network performance. This advancement laid the foundation for the widespread adoption of smartphones and data-intensive applications.

The Sunset of 3G: Why Now?

As technology advances, older networks become outdated and inefficient in meeting the growing demands of consumers. The decision to phase out 3G is rooted in the pursuit of more efficient and advanced network technologies. The spectrum that 3G occupies will be repurposed for newer technologies like 4G and 5G, offering users a more robust and future-proofed network experience.

Implications for Roaming SIM Card Users

1. Assessing Current Network Compatibility

For users of roaming SIM cards, it’s crucial to assess the compatibility of their devices with the newer network technologies. While most modern smartphones support 4G and 5G, older devices may only be equipped with 3G capabilities. Upgrading to a 4G-compatible device ensures continued connectivity and takes advantage of the enhanced features offered by newer networks.

2. Transitioning to 4G Roaming

As 3G services wind down, roaming SIM card users should consider transitioning to 4G roaming services. Many providers already offer 4G roaming options, delivering faster data speeds and improved overall network performance. Contacting your roaming SIM card provider to understand their 4G offerings and making the switch is a proactive step toward maintaining seamless connectivity.

3. Future-Proofing with 5G

While 4G offers substantial improvements over 3G, the future of mobile networks lies in 5G technology. Users who wish to future-proof their connectivity should explore 5G-compatible devices and roaming options. Though 5G networks are still expanding, staying ahead of the curve ensures a cutting-edge mobile experience.


The sunsetting of 3G services by EE in 2024 marks a pivotal moment in the evolution of mobile networks. Roaming SIM card users must adapt to these changes by assessing their device compatibility, transitioning to 4G roaming services, and considering the possibilities offered by 5G. Embracing these advancements ensures uninterrupted connectivity and positions users at the forefront of the ever-changing telecommunications landscape. As we bid farewell to 3G, let us welcome the next era of mobile communication with open arms.
