Can I make an international call directly from a domestic ordinary telephone?

Ordinary mobile phones can't make foreign calls directly, and they need to open international long-distance service in the business hall, but they can answer foreign calls and send and receive foreign short messages.

Four ways to make international calls:

1. Direct dial. Use the operator's network to make international calls directly. This function can only be used after applying to the operator. When using, directly enter the area code+telephone number of the country to be dialed.

Take the United States as an example The international area code of the United States is 00 1, and the telephone number of the United States is ten digits, so if you want to call the United States, enter 00 1? xxx？ xxx？ xxxx(xxx？ xxx？ Xxxx is a ten-digit telephone number). Direct dial telephone has almost no disadvantages, but it is very expensive.

2.IP phone dialing Now many communication operators support IP phone dialing. IP telephone dialing means that the operator gives you an IP (for example, 1795 1, 17909). After dialing this number, enter the international number you want to dial according to the prompt and you can make a call. This method is cheaper than direct dialing, but it is still very expensive.

3. Calling card dialing is a relatively cheap dialing method. At present, there are two kinds of calling cards on the market, one is a physical calling card and the other is a virtual calling card. The dialing method of the two cards is the same. Dial an access number first, and then enter the international number to be dialed according to the prompt.

The disadvantage of calling a phone card is that it is more troublesome. However, one calling card is different from other calling cards. The name is "Shanshan Card". The difference between Shanshan card and other cards is that Shanshan card uses callback method, that is, after you dial the access number, the system will automatically hang up and call you back.

Then you answer the phone and enter the international number you need to dial according to the prompt. This function is mainly to make the call network more stable. Moreover, Shanka system can also record the number you dialed, and you only need to enter the last four digits next time, which reduces a lot of trouble. It is the best international long-distance telephone card in the industry.

VoIP is the cheapest way at present. IDD calls are made through specific VoIP software, but Internet support is needed. At present, there are many kinds of VoIP in China, and the quality and tariff are also uneven. VoIP is limited by network signals.

When the network signal is not good, the call quality is not very good. Of course there are exceptions. There are two kinds of VoIP software that do not need to go through the internet during the call. Namely IDD and totospeaker. The main feature that distinguishes these two softwares from other softwares is that they only need a little traffic (about 1kb) when dialing.

During the call, the Internet is not used, but the original operator's network is directly used, and the cost is only the cost of VoIP, which not only ensures the call quality, but also does not have to pay high communication fees. These are two products that are currently in the leading technology in the industry.
