Replace the USIM or reissue the eSIM

A new USIM or a reissued eSIM comes with a new authentication key, so a SIM copied from the leaked key no longer works on the network.

How to do it

  1. Ask your carrier for a USIM replacement or an eSIM reissue through its app, website or a store.
  2. Take your ID card if you go to a store.
  3. After the switch, check that calls, texts and mobile data work with the new SIM.
