Unusual Charge

[BSPradhan]

Hi

I got an unusual charge in Sep2022 bill, that shows the followng:

31 Aug 22 04:30:00 idata.o2.co.uk IND 11310 66.277

This is under the data usage while abroad.

While I am abroad, my roaming data is OFF. Then how can this happen ?

Regards

I've seen some evidence over the years that iPhones, under some circumstances, can use data even if it is switched off. Usually it is associated with iMessages or Visual Voicemail
