Erik Lyneborg is angry after receiving a phone bill for thousands of dollars.

Lyneborg recently returned from a trip to Mexico.

He used his Apple iPhone for about four hours during his vacation to keep in touch with clients back in Canada.

When he received his bill, he was shocked to discover that he had been billed six thousand dollars for the service.

Rogers tells CTV that roaming rates are the same for all phones and iPhones have a setting to switch roaming on or off.

But if the phone is switch to roam internationally, it may be accessing the network without its user's knowledge.

All the major cell phone carriers have different plans designed to limit charges for people using their phones overseas.

Anyone thinking of using their phone on a trip should check with their provider before making a call.
