A UK customer says they return from a five-week trip to Thailand and find a mobile phone bill from O2 for £159,230.06. The report says the charge appears linked to phone use during the period of the trip, and the customer describes being shocked by the size of the bill.

The article presents the case as a warning and says the customer spends hours trying to resolve the issue with O2. It also frames the story around steps readers can take to reduce the risk of unexpected roaming or billing charges while abroad. Other details of the underlying cause of the bill—such as how roaming was enabled, what services were used, or whether the provider has issued a formal explanation—are not included in the provided excerpts.

Overall, the sources presented here focus on the same reported figure and the customer’s attempt to address it with the operator.
