Why does my SIM show “No Service” in a new device?

If your SIM card works fine in your old phone but shows “No Service” when inserted into a new device, this is usually because many carriers (including Good2Go, Assurance, and Metro) link a SIM card to one specific device IMEI (the phone’s unique ID).

When you insert the SIM into a different phone (such as the Eclipse L1), the carrier’s system still sees the SIM registered to your old device and blocks service.

How to fix it:

• Please call your carrier’s customer service:
  • e.g., Assurance: 1-888-321-5880 Metro: 1-888-258-1974
  • Tell them you need to move your SIM service to a new device.
• Before calling, prepare the following:
  • Your phone number
  • The new phone’s IMEI
  • Your account PIN
• The carrier’s support team will:
  • Remove (unbind) your old device IMEI.
  • Update your account with the new phone’s IMEI.
  • Reactivate your SIM card on the new device.

Once this update is complete, your SIM will work normally in the new phone.
