Having 2 phones on one line, does it make the phones slower?

Having 2 phones in one line does it make the phones slower

If you have 2 phones in one line does it make the phones internet run slower or is it the same because I heard having a family plan can make the phones slower because your sharing data? Is it true or false

Haven't seen this on AT&T Family Share Plan. Can you mention your carrier?

A line is the actual phone number you're using so it is not possible to have two devices on the same line. You can have 2 devices on the same account but that will in no way affect your internet speeds.
