I have a Motorola with Verizon service. I don't even know how to send a text message, but I can take a photo (I have an extra data card for the phone) and transfer it to the computer. I couldn't phone it to anyone though!
When our contract (which is through my husband's work) is up we'll choose phones we can use in Europe. Apparently there's some kind of chip that is compatible with their systems..... my husband is the digital wonk! I just handle the cooking.
