লক্ষ্য করুন এই ডিভাইসটি এ্যকটিভেট করতে সক্ষম হয়েছি উবুন্টুতে। Dear bloggers I have got one laptop (Toshiba M505-S4945) few days back bought from usa. There is a mobile broadband device in it. I inserted the SIM card of GP and Aktel in it and tried to use it. But the WWAN Connection Manager application always says "No signal available". I guess the device is locked that can be used only in USA and needs to be unlocked. Did anyone faced such problem or have any idea how to use that device to use internet using our local GSM network. Please note, the modem type is HSPA.
