With the help of the Walt Disney Co, parents can make sure it’s still a small world for their children, at least when it comes to their cellphone use.

On Wednesday, the company will introduce a wireless phone service that will allow parents to set limits on their children’s cellphone use as well as track them on a map using Global Positioning System technology.

Parents can determine what hours and days of the week children can use phones, blocking school hours for example, and what numbers they can dial. They will also be able to set spending limits on their phone bills.

The new service, called Disney Mobile, has not been priced yet, and will be available in June.

Disney, like many media companies, is hoping to take advantage of the proliferation of cellphones by offering services of its own, like ring tones and wallpaper. “This is very much about putting control in the hands of the parents,” said Steve Wadsworth, president of the Walt Disney Internet Group.

As part of the mobile service, parents can set up a monthly allowance of minutes, text messages or other services for each child to use. Once a monthly allowance is reached, both the parent and the child receive an alert on their Disney Mobile phones. The parent then can decide either to increase the allowance or restrict the phone’s use.

Parents can also use an online tool to designate when phones can be used and what numbers can be dialed. Certain numbers, like the home number, can be programmed to always be available in case of an emergency.
