We know how frustrating signal issues can be, especially for business customers and although network coverage is better than ever, temporary faults can occur.

More than any other usage type, text messages can affected by issues of high demand on a particular cell  tower, so the issue may only manifest itself at certain times of the day. Urban areas can be particularly affected.

If you're experiencing drops in service in more than one postcode area, a loss of or drop in signal strength is unlikely to be the cause of the problem.

Check the current status of the O2 network for the affected postcode, here: https://status.o2.co.uk/

If a fault is recorded, the network will be doing everything possible to rectify the problem, quickly. It's a hard fact, but there is no magic resolution and we ask for your patience and cooperation while service is fully restored. 

If you're experiencing drops in service in more than one postcode area, to determine if the problem is related to your phone or SIM card, switch off your phone, remove the SIM, reinsert and switch on.

No improvement? Insert your SIM card into an unlocked phone or another plan.com user's phone. If service improves, the fault is with your handset. If not, you require a replacement SIM.

In both scenarios, your sales account managers will be able to provide the resolution.
