Checking if Redmi’s latest flagship works with UK 5G networks

The Redmi K90 Pro Max has sparked strong interest among UK smartphone buyers looking for flagship-level performance at a much lower price. But before considering an import, one of the most important questions is whether the device fully supports 5G connectivity on British networks. Understanding its band compatibility is key to knowing how well it will perform in real-world use.

The Redmi K90 Pro Max supports a wide selection of 5G frequencies, including n1, n3, n7, n8, n28, n38, n77, and n78. These cover the majority of global 5G standards, meaning the phone can connect to both mid-band and low-band 5G signals used in most regions. This wide range of support gives it strong potential to perform effectively on multiple UK networks.

In the United Kingdom, the main 5G bands used are n78 and n28. Band n78 operates around 3.5GHz and is used extensively by EE, Vodafone, and Three for high-speed coverage in urban areas. Band n28, which operates at 700MHz, is used for extended coverage and better indoor reception. Since the Redmi K90 Pro Max includes both of these crucial bands, it should have solid compatibility with most UK 5G networks.

For users on networks like O2, which also use n1 and n3 in some areas, the Redmi K90 Pro Max remains compatible. Its wide coverage of mid-band frequencies means users can expect reliable 5G service, though performance may vary slightly between carriers depending on region and network rollout.

It’s also worth noting that the Redmi K90 Pro Max supports a comprehensive set of 4G and 3G bands. This ensures strong fallback coverage when 5G signals are not available, an important consideration for rural or suburban users where 5G is still expanding.

However, there are a few practical points for UK buyers to consider. Since the Redmi K90 Pro Max is designed primarily for the Chinese market, the global variant has not yet been confirmed. Imported models might lack official certification for UK networks, which could limit access to certain carrier-specific features like VoLTE and Wi-Fi calling. Additionally, warranty and after-sales support for imported units may not be available locally.

Another factor is software optimisation. The Chinese version of the device typically runs MIUI with preloaded regional apps and settings that may not be ideal for UK use. While switching to the global ROM can help, it may not be officially supported until Xiaomi launches the model internationally.

Despite these caveats, the Redmi K90 Pro Max remains technically compatible with the key 5G bands used in the UK. Users who import it can expect to enjoy fast data speeds and stable coverage on most networks, provided they configure the correct settings and choose compatible SIMs.

In conclusion, the Redmi K90 Pro Max offers full 5G support for the UK’s essential frequency bands, including n78 and n28. It should deliver excellent connectivity and download speeds comparable to local flagships. The only caution for buyers is ensuring they get the correct variant and understand the potential limitations around warranty and software updates. For those comfortable with importing, it stands as a powerful, 5G-ready option at a fraction of flagship prices.
