4g not working or connecting

[Kels361]

Hi I was late paying my bill but paid it early today and normally within the hour my phone is back connected and I'm able to use it again. However it's been 12 hours and nothing has happened and I'm still not able to make phone calls or use any roaming data but I am able to still send text messages

You need to contact customer service

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
or give them a call on 202 or 0344 809 0202

As this sounds like a regular occurrence, you should set up a direct debit to pay on time @Kels361

How many times have you been late paying?

There comes a point where they will refuse to reconnect you.
