“P” on an iPhone call usually means Primary — it’s the label for your main SIM or phone line, especially on dual-SIM iPhones. It can also reflect a custom line name, but Primary is the default.

What it means

  • If you have two lines on your iPhone, Apple uses letters to show which line was used for the call.
  • “P” commonly stands for Primary or sometimes Personal , depending on how the line is labeled.
  • If you renamed your lines in Settings, the letter may match that name instead.

Quick check

  1. Open Settings.
  2. Tap Cellular or Mobile Data.
