Coverage varies significantly between Vodafone, EE, O2, and Three depending on your exact location. No single network has the best coverage everywhere in the UK.
To check coverage at your business locations:
- Use Ofcom’s Map Your Mobile tool for independent, crowd-sourced signal data
- Check each network’s own coverage checker (though these tend to be optimistic)
- Ask Connection Technologies for a free coverage analysis — we use independent Ofcom data to check all four networks at your specific postcodes
We recommend checking coverage at your office, warehouse, key customer sites, and regular travel routes. The best mobile deal is worthless if you cannot get a signal where you need it.
