The BlackBerry Storm 9530 is an international and worldwide electronic communicating device, featuring CDMA with EV-DO Rev. A data, UMTS with HSDPA, and quad-band GSM with EDGE data access speed. [...] However, the BlackBerry Storm only has European, Oceania, Asia and Brazil UMTS and HSDPA frequency bands. Therefore if the BlackBerry Storm is used with GSM wireless carriers in North America, the BlackBerry Storm will only be able to access wireless internet at EDGE data speed maximum. This is because GSM carriers in North America, namely AT&T, T-Mobile, Rogers and Fido do not operate on the same frequency bands for 3G as the rest of the world. If BlackBerry Storm is used in Europe, Africa, Asia, Oceania or Brazil, HSDPA wireless data speed can be achieved, provided that the local GSM network supports it. The phone will use the primary network technology of its intended carrier domestically, and rely upon the GSM/UMTS/HSDPA networks mainly when traveling abroad.
