By Muhammad Shahid · · 4 min read
Quick answer
+[number]: The plus prefix works from anywhere, including abroad. The plus sign is a placeholder the network replaces with whatever exit code the country you are standing in uses. Because of that, a number stored as plus, country code, then the local number will dial correctly from the US, from Japan and from Germany without ever being edited.
