According to research from CCMI, an information source for the telecommmunications industry, most Fortune 1000 companies are exploring options to control high wireless bills incurred from international business.

"These survey findings highlight the fact that among the biggest organizations in the country, the cost of roaming is a genuine pain point and significant expense item," says Gary Cohen, senior vice president and general manager of Truphone Americas, which commissioned the survey. "There is also evidence that small- and mid-sized companies are burdened with the same challenges."

The report finds that 40 percent of respondents are banning or restricting business usage of wireless devices while abroad to help control costs. Another 24 percent of respondents say they have lost business as a result of roaming costs, and 37 percent of respondents cite spending an average of $1,000 or more per month per user for wireless roaming costs for their international travelers. In some cases, there have been single monthly bill charges ranging from $10,000 to $200,000.
