Unable to make calls from abroad

[JazzCoops]

I’m in Greece and cannot make any calls. Please tell me what I need to do to resolve this.

Thank you.

Make sure you are connected to a Greek Network
Change the Network to another one

Check your TIme Settings

If none of the above work  you’ll need someone to access your account which can’t be done from here. if you send them a message on Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG), or you can call 202 from your o2 phone

Just to add to the above

          *Make sure data roaming and mobile data is turned on in your phone's settings.

          * If you have an iPhone change your data APN to "mobile.o2.co.uk"

           * Try toggling Airplane mode on/off (it often helps kickstart things)

           * Drop down to 3G and see if that helps.

           * Contact O2 to see if there are any roaming bars on your account.obile on +44 7860 980 202.

You can call them from abroad for free from your mobile on +44 7860 980 202.

If nothing works, then think about using a local PAYG sim.

Best of luck.
