This router is increasingly difficult to source - we recommend the Teltonika RUTX50 as a fast, reliable alternative.

The 5G CPE Pro 3 (H138-380) is the flagship 4G/5G router from Huawei, supporting 5G standalone (SA) and nonstandalone (NSA) networks, including all UK carriers. It supports up to 4x4 MIMO and 256QAM to achieve a maximum theoretical downlink rate of over 3.6 Gbit/s. It's one of the fastest routers available on the market today.

However, the 5G CPE Pro 3 (and its 4G sibling, the B628) make it very difficult to attach external antennas, which has made them challenging to use in areas of low 4G or 5G signal strength. To solve this, we've teamed up with router-mods.co.uk to offer a 5G CPE Pro 3 router pre-modified for use with external antennas.

All internal antenna connections have been re-routed to the outside of the case, and are exposed as eight secure SMA-female connections on the side of the router. This allows you to easily connect up to four Bluespot 4G/5G antennas and achieve blisteringly fast internet, even in remote areas.

For more information about the router modification service, take a look at the router-mods FAQ page.

This item is a brand-new modified router, and the manufacturer's warranty does not apply. Instead, we guarantee the router and workmanship for a period of 3 months after purchase. In the event of a technical fault, we will repair or replace it at our discretion, per our returns policy.
