Hi, I will be traveling to Europe in a few days and I want to take my phone with me but I want to avoid getting a bunch of extra charges. I already called TMobile and the told me to turn the phone off when I'm not using it, because I'll get charged for any incoming calls even if I don't answer them. I'm wondering though, if there's any way of turning off the "phone" without turning off the actual phone. I'd still like to use the alarm and calculator, etc but I don't care about using the phone or internet. Help!
