Traveller faces 160000 phone bill after Thailand trip

A London businessman returned from a five-week holiday in Thailand to find a bill for £159,230.06 from O2. The charge was for mobile data usage during his trip to Phuket and a health retreat where he trained in Muay Thai. At first, he assumed it was a billing error, but the telecommunications giant confirmed the amount was correct.

The unexpected invoice threatened the future of his plumbing and heating services operation. He had used the phone for just six days of the trip, relying on information provided before he traveled that a £7.50 daily charge would cover his usage. He spent hours trying to resolve the issue with O2 and ICE Comms, the third-party company responsible for his contract, but felt passed between them without a solution.

A Massive Data Overhang

Records indicated he had used 27GB of data while abroad. To put that figure into perspective, that amount of data might be consumed by streaming just nine hours of high-definition programming. For the same sum, he could have purchased a brand-new Porsche 911 GT3 sports car or ten Rolex Datejust watches.

He remains adamant that he checked in advance with ICE Comms and was assured the roaming package had been applied to his account. The irony here is that he was wary of paying even the extra daily pass charge, which is why he limited using his phone to just six days of his trip. When neither company could explain why the daily pass had not been applied, he sought outside assistance to mediate the dispute.

This situation highlights a recurring vulnerability where small business owners are caught between mobile carriers and the third-party brokers that manage their contracts. When administrative settings slip through the cracks in that chain of communication, the customer often bears the immediate financial shock while the two companies dispute responsibility.

Carrier Intervention

Upon review, O2 stated that it could find no record of a request for optional spending caps to be actioned. However, within 24 hours of the case being escalated, the firm agreed to wipe most of the bill. The final charge was reduced to about £50 on top of his usual monthly payment.

“We always aim to do the right thing by our customers,” a spokesman for O2 Business said. “As soon as this matter was brought to our attention, we acted swiftly to review the case, spoke directly with Mr P and reached a resolution he was happy with.” ICE Comms did not respond to requests for comment regarding the failure to apply the roaming package.

Preventing Shock Charges

O2 urges customers to regularly check spending controls and account settings on mobile devices, particularly before traveling. Tourists can limit roaming to navigation apps and make use of free Wi-Fi to avoid high bills. Another option is to temporarily replace a phone’s physical SIM card with a cheaper local version.

Modern phones also support eSIM, which allows users to purchase a plan online and install it, typically using a QR code. Regardless of the method chosen, the phone must be unlocked to access other networks. Apple devices usually display “No SIM restrictions” under network provider lock settings. For Android users, tapping settings, then network and internet, will show if the device is unlocked or restricted to a specific carrier.
