O2 offers strong UK mobile coverage through the Virgin Media O2 network, with 4G and 5G available across many areas. For businesses, the most important thing is not just national coverage claims, but whether O2 performs well where your team actually works.
Before choosing O2, check coverage for:
your office or shop
staff homes if they work remotely
client sites
delivery routes
rural locations
event venues
regular travel routes
areas where mobile hotspot use matters
If your business depends heavily on mobile data speed, compare O2 against EE, Vodafone and Three using your actual locations.
O2 Business Mobile roaming
O2 is often appealing for businesses with staff who travel in Europe. O2 says that when travelling in Europe, roaming in its Europe Zone is included in your UK allowance unless you have a special tariff.
O2 also says Small Biz SIM-only plans have UK-to-EU minutes and texts depending on data allowance. For example, 20GB–50GB plans receive 500 UK-to-EU minutes/texts, while unlimited plans receive 2,000.

Their main strengths are value, EU roaming, small business tariffs and flexible plan options and their main drawbacks are mixed customer service feedback, recent complaint concerns linked to price-rise communications and lower suitability for complex enterprise mobile management.

you are a sole trader or small business
your team travels in Europe
you want SIM-only or handset options
you value O2 Priority and high-street support
O2 coverage is strong in your working locations
Consider alternatives if:
you need premium support
you want the fastest overall network performance
you need advanced MDM or compliance controls
you are concerned about price-rise terms
you want a managed business mobile provider
your staff work in areas where O2 coverage is weaker
Overall, O2 is a good-value business mobile provider for small businesses, but it should be compared against EE, Vodafone, Three and managed business mobile resellers before signing.
