Phone not working

[Danley13]

Hi my phone is not working I can't get any signal at all. I've turned my phone off and back on and I've also turned off my mobile data and back on and I'm still having the same problems, can someone help me, as this has been going on for two days now and I rely on my phone for business and I've lost a few jobs because of this.

We’re just customers like you but it sounds like you’ll need someone to access your account which can’t be done from here. If you message O2 using the links below, they should be able to help you with this

@Danley13 Could be a faulty sim. If you have an O2 store nearby, call in and they'll swap it for you. Be sure to bring photo ID with you.
