There is a sim slot in my lenovo b470. so I insert an EVDO simcard but could not detect sim in windows 7. so will someone help me to surf internet using that simcard or other GSM data simcards. I also searched utilities and drivers related to it in lenovo's official site and also googled but couldnot find proper solution..
of course it is sim card slot and it is in inner part covered by battery cover and there is extra card reader slot. I am 100% sure it is sim slot. model of laptop is lenovo B470
