The best business iPhone deal this week is the iPhone 16 on EE Business at £37.99/month with unlimited 5G data on a 24-month contract. This beats O2’s equivalent offering by approximately £3/month and includes EE’s superior 5G network speeds.

For businesses on a tighter budget, the iPhone SE 4 on O2 Business at £22.99/month with 50GB data is an excellent alternative. You’ll get Apple’s latest chip, Face ID, and full iOS compatibility at £15/month less than the iPhone 16.

Our pick for iPhones: EE’s iPhone 16 deal for power users; O2’s iPhone SE 4 for cost-conscious businesses.

Our pick for Samsung: The Galaxy S25 on Three — flagship performance at a mid-range price point. Unbeatable for most business users.

What Is the Best Unlimited Data Business Mobile Deal?

If unlimited data is non-negotiable, the Samsung Galaxy S25 on EE Business at £34.99/month with truly unlimited 5G data is the best deal this week. EE doesn’t throttle speeds on its unlimited business plans, making this ideal for employees who tether frequently or use data-heavy applications in the field.

For unlimited data on an iPhone, EE’s iPhone 16 at £37.99/month remains the top choice.

Best for unlimited data: EE Business consistently offers the best unlimited data experience thanks to its superior 5G infrastructure. The £3-£5/month premium over Three and Vodafone is justified by noticeably faster speeds.
