Hi i'm new here but i recently got a Nokia 8890 With Att wireless. and i have a couple of questions. At my house i get horrable reception with ATTWS but on my phone theres a function that allows me to select different networks and cingular is on there. usually its on automatci and it chooses ATTWS but when i switch to Cingular manually i get much better reception and less dropped calls. So my question is if i use the Cingular network will i get charged more? Will i still be able to use my ATT unlimited mobile to mobile while i'm using the cingular network? Thank you!
