China Mobile Communication Group Company, still under preparation for establishment, opened at 9:00 am, December 2, a 1.9G GSM network automatic roaming business to 13 states of the United States. As a result, the scope of access for China's mobile communication GSM international roaming business has extended from the original Asia, Europe, Africa and Oceania to five continents including North America. Because American GSM operators use the 1900 MHz frequency, therefore, while traveling in the United States, Chinese mobile communication subscribers, in addition to the use of SIM cards which remain unchanged, need to have mobile phones to adapt to the American 1900 MHz frequency. |
