How to make a phone call if you want to go abroad and roam internationally?

When roaming in international, Hong Kong, Macao and Taiwan regions, the dialing method is as follows: 1. Call roaming local phone: dial the local user number directly. 2. Calling international fixed telephone in non-roaming places: international access code+country code+area code+fixed telephone. For example, roaming to the United States requires dialing 018610 fixed telephone (Note: 0 1 1 is the international access code of the United States, and GSM network countries are also required. 3. Calling international mobile phones in non-roaming places: international access code+country code+mobile phone number. For example, when roaming in the United States, you need to dial 0 1 186 mobile phone number to call the mobile phone users in Beijing, China. International roaming means that mobile phone users can continue to use their mobile phones for voice, SMS and Internet communication in other networks in other countries and regions after leaving their home networks. At present, China Telecom has opened CDMA and GSM international roaming services with operators in more than 200 countries and regions around the world, and the roaming access range is still expanding. In these countries and regions, you can continue to use CDMA or GSM mobile phones for communication.
