Three Business Launch Large-scale UK eSIM Trial for 50,000+ Businesses

Three Business, the business-to-business arm of mobile network operator Three UK, this morning claims to have launched the “UK’s first large-scale eSIM trial” for over 50,000 business, albeit initially only available to those in the Birmingham and Bristol areas. The trial will allow customers to test Three’s network before making the commitment to switch providers.

Unlike physical SIM cards, eSIMs embed an electronic SIM into your device (Smartphone) that could – once fully implemented – make it easier and quicker to switch between operators (e.g. not having to wait for a SIM card to arrive) and to use additional networks alongside your main mobile service (e.g. eSIMs for travel when abroad).

However, so far eSIM based services have tended to be more focused on consumers, but Three Business are looking to change that. Switching mobile networks can be a big decision for businesses too, with coverage and service quality varying significantly by location. Traditionally, businesses have relied on coverage maps, external reports, and third-party analysis to make their choice, but these tools don’t always reflect real-world conditions.

The goal of the new eSIM trial, which will be delivered in partnership with eSIM Go, is to allow businesses to experience the Three network first-hand for 30-days alongside their existing provider. This will allow such firms to make a more informed decision based on actual performance.

Snehal Bhudia, Director Three Business, said:

“Choosing the right mobile network can feel overwhelming with conflicting information and the risk of getting it wrong. That’s why we’re offering businesses a free trial of our market-leading 5G network – alongside their current provider. It’s a simple, hands-on way to experience the difference for themselves, helping them make a confident, informed decision that drives real productivity gain for their business.”

The two cities were selected by Three Business due to their rapidly growing business ecosystems and status as major UK tech hubs. But it’s currently unclear how long the new trial will run for or when the final service might launch.
