What happens if I go over the fair usage policy in Glasgow?
It depends on the network. As of August 2026, Three is more flexible and lenient with its fair usage policy, and it is rare that we need to warn customers. Vodafone and O2 are much stricter: if you go over more than twice, you will be notified to monitor your usage.
