Replacing your SIM

You need a replacement SIM if:

  • Your SIM is defective or was stolen.
  • Your SIM is obsolete and must be replaced (this applies to all SIM that were issued before 2002).
  • Your new phone requires a new MICRO SIM or a new NANO SIM.

You can obtain a replacement SIM from any Swisscom Shop. Ask the Shop staff to assist you with transferring the contacts from your old SIM / your old device to your new SIM / your new device.
