    Is my phone network locked?

    HI,
    I am trying to find out if my S4 is tied to Tesco Mobile in the UK.

    AP:I9505XXUEMKF

    CP:I9505XXUEMKF

    CSC: I9505BTUEMK5

    any help would be appreciated.

    The CSC has BTU in it.
    BTU is the Samsung code for an 'open' non network UK firmware.

    The only real way to check if your phone is locked is to insert your sim card.
    If you are not asked for a code, your phone is either unlocked or locked to your sim's network.

    If bought through Tesco mobile, unfortunately Tesco add another network lock. But again, you can check by putting in another (not Tesco) sim card.

    If you are asked for a network unlock code, it will be for Tesco.

    Thanks for that.

    But as for the firmware if BTU is none network firmware, does that mean that any updates are from Samsung and not network dependent?

    Then it is not locked to the network or you are updating with the Meteor firmware.
