China's mobile phone card can send short messages to China in the United States?

Hello, China mobile users can send short messages to domestic mobile when roaming abroad after opening the international roaming function, just enter the other party's mobile phone number and send them directly. Sending text messages every day in the United States 1.39 yuan, and receiving text messages in China is free. Text you in China 1 yuan per day. If your mobile phone is not tri-band, low-end mobile phones such as Nokia110 are dual-band-GSM 900 MHz/1800 MHz. I don't know what model and frequency of this low-end mobile phone you are using, so it can't be used in the United States. Please see the following explanation: In America, Canada and other American countries, most operators' networks are GSM 1900MHZ, and roaming in these countries requires a tri-band mobile phone (900 MHz/1800 MHz/1900 MHz). At present, most mobile phones on the market support tri-band. In the United States, in addition to using a tri-band mobile phone, you can also use an IDEN mobile phone. If you don't use a tri-band mobile phone, you can buy a tri-band mobile phone or rent an IDEN mobile phone from NEXTEL in China to roam in the United States. This kind of mobile phone can be used in China and the United States. Just insert the SIM card with international roaming function into the mobile phone. 1. Go through the formalities: show the customer's valid ID card and certificate, and pay the mobile phone deposit. Please contact 10086 for details. 2. Return the plane: you need to go to the business hall to rent the plane as soon as possible after returning home. China Mobile answers for you.
