The Prepaid subscription PIN is by default 1234. Prepaid with normal SIM card: Retain your Prepaid starter kit, as the Prepaid PUK code can only be found on the SIM card frame. Prepaid with eSIM: retain your Prepaid order confirmation, as as the Prepaid PUK code can only be found there. It is not possible to get the PUK code for a Prepaid subscription via OmaElisa or Elisa’s customer service. If your phone requests a PUK code and you no longer have access to the card frame, the Prepaid subscription can no longer be used.
