"Unsupported Phone" Error When Using an Old CDMA SIM Card to Activate a Phone Not Bought Directly From Republic Wireless


  • Unable to activate a phone not directly purchased from Republic Wireless using an old SIM card
  • Receives a message the phone is unsupported when inserting the SIM card
  • Phone may be a manufacturer replacement phone or a phone a member purchased on their own


  • Bring Your Own Phone (BYOP) activation
  • Original SIM card is CDMA


  1. Order a GSM SIM card from the Republic Wireless Online Store
  2. Once you receive the new SIM card, activate your phone using the new SIM card


A CDMA SIM card cannot be used to activate a phone that was not received directly from Republic Wireless, even if the new phone is an identical model to the current one 

Additional Information

If you'd like to use CDMA service with the new phone, open a Help ticket and provide the following information for Republic Help to review

  • The IMEI of the phone
  • From where it was obtained (retailer or manufacturer, used, etc.) 
  • Shipping address for CDMA SIM card

NOTE: Republic Help may require additional information regarding the phone.  Additionally, the phone must be compatible with CDMA service.
