O2 business mobile contracts: what to check
Before you sign any O2 business mobile contract, check these points in the written offer:
- Contract term. Business contracts arranged through Compare The Networks run for a minimum of 24 months. Handset contracts can be longer, so confirm the end date for every line.
- Handset or SIM only. A handset contract spreads the cost of the phone across the term. If your team already has suitable phones, a business SIM only deal usually means a lower monthly cost.
- Total contract cost. Add the upfront charge to every monthly payment over the full term, and compare that figure rather than the headline monthly price.
- Mid-contract price rises. New contracts must state any annual price rise in pounds and pence. Check the amounts and the month they apply.
- Roaming. Confirm what is included for the countries your team visits and what happens outside those destinations.
- Number porting. You can keep existing numbers by requesting a PAC code, for example by texting PAC to 65075. The switch usually completes on the next working day.
- Business support. Ask how faults, lost phones, new lines and SIM swaps are handled, and who your point of contact will be.
