"URGENT" Using iPhone 5 Abroad

[Anonymous]

Hi, I am currently an iPhone 5 user, pay monthly with 1GB data.

I am currently abroad in South Korea and I have switched off my cellular data by putting my phone into an airplane mode. However I have my wifi switched on, and have been using my home wifi since. On "My O2" application, it states no additional charges on "Recent Charges" banner due to Data or International. 

Yet, I am not sure if by the end of the month, I will be charged for wifi usage. 

Please contact me as soon as possible to confirm it to me and make it absolutely clear so that I can not spend my time worrying about this.

Many thanks.
