Microsoft Steps In To Investigate Mystery Windows Phone 7 Data

Microsoft is to investigate its Windows Phone 7 software after reports emerged that it is sending and receiving mystery data.

The BBC has reported (opens in new tab) that users have complained that the phone is consuming data without their knowledge, resulting in their data plan allowances being quickly spent.

One concerned user wrote on Microsoft advocate Paul Thurrotts’ website (opens in new tab): “I received an e-mail from AT&T saying that I was close to my 2GB data limit which truly shocked me as I feel I do not use data that much. I went and looked at my AT&T account online and noticed that my phone was sending huge chunks of data seemingly in patterns.”

According to the BBC, some users are experiencing idle data usage of around 2-5MB per hour.

"We are investigating this issue to determine the root cause and will update with information and guidance as it becomes available," a Microsoft spokesperson told the BBC.

It has been speculated that the cause of the problem could be due to the phone’s software sending performance data to Microsoft, or from the devices accessing 3G even if a Wi-Fi service is available

At CES this week Microsoft CEO Steve Ballmer announced a range of upcoming updates for his company’s new smartphone operating system, including a long awaited copy/paste function.

It is not yet known whether this problem is affecting users in the UK, or if it is limited to the US.
