What should I put before sending a message to an American mobile phone card?

1. China Mobile: Users can use the international SMS service without applying. After editing the short message, enter: international code (00)+ country code+user number at the sending number to send international short messages.

China mobile communication customers send international short messages to operators outside Chinese mainland, and the tariff standard is 1.00 yuan/message.

After roaming to countries and regions outside Chinese mainland, the tariff standard for China mobile communication customers to use international short message service is: roaming short message sending tariff standard ×115%+1.00 yuan/article.

China mobile communication customers receive international short messages for free.

Second, China Unicom: China Unicom's short message international interoperability service, whether GSM users or CDMA users of Unicom, can send short messages to mobile phone users in 100 countries and regions including Hong Kong, Macao and Taiwan.

Domestic Unicom users do not need any opening procedures, as long as they fill in the sending number in the format of 00+ country code+user number, they can send short messages to foreign mobile phones. For example, when a Unicom user sends an international short message to a mobile phone user in the United States, the American country code "00 1" should be added before sending the number.

Similarly, foreign users can send it to China Unicom, fill in the international code 0086+ China user number, and it can be sent to China Unicom's mobile phone users.

Charge: 0.8 yuan/article, free of charge.

Different countries have different tariffs.

Sending peer-to-peer messages is the most economical way to travel.

Near the summer vacation, many citizens choose to go abroad or travel abroad. How do they roam abroad with their mobile phones and how much do they charge? Many citizens still don't understand this.

It is more expensive to receive text messages from the secretary desk.

A senior tour guide of a travel agency in Jiangsu said that many tourists choose to turn off their phones or not answer their phones when they go abroad, but they set themselves a "set". It turns out that many tourists don't answer their phones or turn off their phones after leaving the country. They usually open voice mail or manual secretary service desk before leaving the country, and then receive calls and text messages after leaving the country. If necessary, they can buy a local calling card to call back. But in fact, when a visitor's voice goes to voice mail, the charge is higher. Because the outbound mobile phone of domestic users has to be dialed to the network of overseas operators first, then the call is transferred to China, and finally it is sent to you by SMS, which is equivalent to charging international calls twice.

Different countries have different tariffs.

It is reported that the tariff standard for mobile phone roaming abroad is generally determined by domestic mobile companies and overseas companies through consultation, which leads to different telephone and SMS charges for roaming to different countries or regions, and even different companies' networks are used in the same area, and the charges are different. Generally, it is "local call × 1 15%, plus 0.8 yuan RMB × 1 15% every 6 seconds". Generally speaking, the "local call charges" here will be surprisingly more expensive than domestic charges after being converted into RMB. For example, in Thailand, the cost of answering a domestic call is about 13 RMB per minute. Therefore, it is suggested to know the roaming tariff standard of the destination you want to go to before going abroad, so as to be aware of it. In foreign countries, the cost of making a domestic call is generally "local phone call ×115%+ID-D ×115%/minute". For example, in Thailand, the cost of making a domestic call is about 12 yuan-15 yuan per minute.

Sending peer-to-peer text messages is cheaper.

"It's cheaper to send peer-to-peer messages. For example, the charging principle for China mobile users to send short messages abroad is: local short message fee × 1 15%+0. 1 RMB per message. For example, in Hong Kong, China, the cost of sending a text message to mainland mobile users using Hong Kong Telecom's network may be close to 4 yuan RMB. " The outbound tour guide told reporters that at present, the cheapest way to travel abroad is to communicate by SMS.
