What does sharing plan mean.?

Does it mean it doesn't matter one of the phone can use for example -1 Gb sharing ?

If you have multiple phones on an account, they will all share a total combined amount of data. If the plan has 1GB as the included data, it doesn't mean each phone has 1GB to use. They all share the 1GB. For example: If one phone uses 750MB of data, in a month, the remaining phones will only have 250MB left to share assuming the first phone doesn't use any more data.
