  • Tap on “General”
  • Tap onto “About”
  • Slide down and look next to “Modem Firmware” – these numbers will be your baseband version

    how do i get my baseband without unlocking the phone?
    when i start it, it says i need to insert a valid sim card inside. without which i cannot do anything on my phone.

    You can get a valid sim card at your local carrier. You don’t have to activate it after purchase, just stick it in and connect your phone to iTunes. The phone will activate and you can chec in Settings –> General –> About.
