Mobile internet is evolving faster than ever before. The growing popularity of high-resolution video streaming, remote work, cloud gaming, and AI-powered services means mobile operators must continuously expand the capacity and performance of their networks. One of the key drivers of this technological transformation in Poland is the rollout of 5G in the so-called C-band.
In 2026, mobile operators are rapidly expanding infrastructure operating in the 3600 MHz frequency band. This also applies to the Plus network, which continues to receive new radio permits to deploy modern 5G base stations across the country.
What does this mean for users? Why is the C-band so important, and how does it improve the everyday mobile experience for Lyca Mobile customers? Here's everything you need to know.
What Is the 5G C-Band?
The C-band covers frequencies between approximately 3400 MHz and 3800 MHz and is widely regarded as the "sweet spot" between coverage and network performance. These frequencies allow modern 5G networks to deliver their full potential by providing:
- Ultra-fast download and upload speeds.
- Extremely low latency (ping), essential for online gaming and real-time applications.
- More stable connections, even while moving.
- Significantly higher network capacity, allowing thousands of users to connect simultaneously without congestion.
In practice, this translates into an entirely new level of mobile internet performance compared to previous generations of wireless technology.
Why Are Mobile Operators Investing in the C-Band?
Just a few years ago, most people used smartphones mainly for checking email, messaging apps, and browsing basic websites. Today, our devices constantly handle 4K video streaming, business video calls, AI-powered services, and smart IoT (Internet of Things) devices.
To keep up with these demands, operators are gradually shutting down older, less efficient technologies such as 3G while reallocating those frequencies- and newly available spectrum- to modern LTE and 5G networks. The C-band plays a crucial role in this transformation.
What Are the Benefits of 5G in the C-Band?
Lightning-Fast Speeds
Websites load almost instantly, high-resolution videos play without buffering, and downloading large files or applications takes only seconds.
No More Network Congestion
In busy locations such as city centers, shopping malls, stadiums, or tourist destinations, mobile networks have traditionally slowed down during peak usage. The new 5G infrastructure significantly reduces congestion and delivers consistent performance even in densely populated areas.
Reliable Connectivity Wherever You Go
Stable mobile connectivity is about much more than entertainment. It also improves navigation, mobile payments, video conferencing, and remote work from virtually anywhere in Poland.
Plus Expands Its Infrastructure - Lyca Mobile Customers Benefit
Lyca Mobile operates in Poland using the Plus mobile network infrastructure. This means every new base station, network upgrade, and C-band expansion carried out by Plus directly improves the quality of service available to Lyca Mobile customers.
As a result, users benefit from broader network coverage, faster mobile internet, and full access to modern 5G capabilities.
According to the latest data published by GSMOnline, Plus has already received 40 radio permits for 5G base stations operating in the 3600 MHz C-band. These new deployments cover both major cities and smaller towns throughout Poland.

5G Expansion and the 3G Shutdown Are Part of the Same Transformation
Mobile operators across Poland are gradually shutting down 3G networks to reallocate valuable spectrum for expanding LTE and 5G services. This transition provides users with faster internet, higher-quality voice calls, and a more reliable mobile network experience.
Do You Need a New Phone to Use 5G?
Not necessarily.
Most smartphones released over the past few years already support 5G. To enjoy the best possible performance, make sure that:
- Your smartphone supports 5G.
- Your operating system is up to date.
- 5G/LTE is selected as the preferred network mode.
- Your SIM card supports current network standards (replacing older SIM cards is recommended, especially during the nationwide 3G shutdown).
