Have searched the threads and can't find an exact answer to this, my ipad2 has 3G and has a "3" sim card in it and it shows on the top left of the main page, but there is no air time as I do not use 3. I shall probably ditch it. Question. can I get my iPad to use my android t- mobile phone unlimited Internet connection? If so how? Or/ Is the only way to use it as such is to purchase another separate sim card. I know I can use wifi if a hotspot is available but that is not what I want to do. Many thanks.
