PITTSBURGH -- Cell phone companies and their service providers have a real marketing blitz under way to promote camera cell phones.

Consumer Reports tested five camera cell phones and their service providers: T-Mobile, AT&T, Cingular and Sprint.

All of the phones let you take pictures and store them on the phone and you can send the pictures to any e-mail address.

You can also send pictures to another camera phone, but only if it has the same service provider.

While the pictures looked OK on the tiny phone display, when the photos were enlarged even slightly on the computer, they weren't clear.

Another drawback is that sending pictures to an e-mail address can be tricky.

Chris Bucsko, of Consumer Reports, said, "All of the service providers but Sprint sent the e-mail with a phone number instead of a name as the return address."

And spam filters can block an e-mail address that's made up of a number.

Still, if a camera cell phone suits your needs, Consumer Reports said your best bet is the Sanyo SCP-8100 phone with Sprint service.

Its streamlined design makes it the easiest to use.

Consumer Reports also said there are other advantages to the Sanyo camera cell phone with Sprint service -- if you want to store your photos online, Sprint has a Web site where you can keep your pictures.
