Can't access my mobile data on a new device following the loss of the original phone.

[Wombat]

Hi, my son lost his phone, we acquired a new sum for the number and a new device, however haven't been able to access the mobile data since it was all reactivated. Can't get through to o2 support on either the phone or chat service. Any ideas please?

You will need to check the Mobile Data Settings.

Full details as to what should be used can be found in the link below:

You'll need to call customer service.

There will be a bar on the account from when phone was reported lost or stolen.

O2 place two bars so I guess only one was lifted when sim was activated.

Numbers here Guide: Coronavirus Community Help and Support 
Or advice from an O2 Guru regarding a way to get through:
If you call 202, when it comes to the reason you are calling stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
Say "Upgrade", "Lost/Stolen" or "Fraud" if you have to, to get put through to someone.
