I'm hearing impaired and I won't be using 450 minutes at all. I cannot justify the expense of paying $39.99 for 450 minutes; not even 20 or 25 cents a minute if going prepaid. Can I go data-only and go with CallCentric for 2 cents a minute outgoing and 1.5 cents a minute incoming instead? That is, when I install sipdroid for Android. Currently, I'm with Sprint using Samsung Ace (Windows Mobile 6.1 with Fring for SIP calls) and my contract does not expire until November of 2010. I'm planning to switch over to Verizon and get Motorola Droid since my mom is with Verizon but if I go with the data-only plan, I won't be able to make mobile-to-mobile calls, unfortunately. It's not like signing up for a free SIP phone service for making only SIP-to-SIP calls, know what I mean? I'm cheap unfortunately, even though I want a Motorola Droid.
