Recently, I purchase a Unimax U670C cell from Kroger Iwireless. It's not the latest greatest, but that's okay since I'm not a heavy cell phone user. I even got the lowest prepaid plan which is $10, 100 minutes monthly, 50mb of data. My goal is to try to make free wifi calls and text. It's running android 2.3 and GrooveIP and Talkatone aren't compatible with my cell. Some other free wifi apps are available that are compatible with my phone, but I'd like to hear what others are using, especially any Iwireless customers. Thanks.
