I have Toshiba Excite 10LE Tablet with Android 4.0(ICS). Purchased this in USA and using in India. I want 3G on this but seems this is not 3G enabled. can I get Browsing/Internet using 3G in this by using a external 3g usb modem? Have seen the device in ebay with name "3G HSDPA USB MODEM DATA CARD 7.2MBPS With Android OS Support" can someone please let me know ASAP?
