Pricing Comparison

O2 has the lowest entry point at £7.50/month for 5 GB on a 12-month contract. This makes O2 attractive for businesses that want flexibility without committing to a 24-month deal.

Vodafone offers better value for unlimited data at £16/month compared to O2’s £25/month. For data-hungry businesses, Vodafone saves £108 per line per year on unlimited plans.

Roaming Comparison

Vodafone is the clear winner for international business use. Their business plans include roaming in 83 destinations at no extra cost, covering most of Europe, the Americas, and popular business destinations in Asia and the Middle East.

O2 includes EU roaming but charges daily rates for destinations outside Europe. If your team travels globally, Vodafone could save you significant roaming fees.

Business Portal & Management Tools

Both networks offer online management portals, but they differ in capability:

Feature	My O2 Business	Vodafone Business Hub
View/pay invoices	Yes	Yes

Block premium numbers	Yes	Yes
Add/remove lines	Yes	Yes
Data usage monitoring	Per-line breakdown	Per-line + alerts
