Independent speed testers

Independent testers inform our network reviews

When it comes to mobile phone coverage and the 4G speeds you can expect with a particular network, you can't just take the provider's word for it at face value.

For that reason, for all our reviews of mobile network speeds and signal strength, we look at the results provided by independent network testing companies.

That way, you can be sure you're getting the full picture when it comes ratings on coverage.
