This phone was never run through a cash register, Tracfone does not ecognize it as valid. You could put an active Tracfone sim card in it and it will work for awhile. I went online to see what can be done and here's what I got:
If a Tracfone branded phone was never scanned at a retail cash register, the phone's internal IMEI number is legally locked in Tracfone’s central database. Retailers use a dual-scan system: the first scan processes the financial payment, and the second scan transmits the phone's serial number (IMEI) to the carrier to whitelist it for activation. This is an anti-shoplifting measure implemented by the carrier. [1, 2, 3]
Because the IMEI is "unscanned," no SIM card from any carrier will work initially—the phone itself will reject activation or block network connection. [1, 2, 3]
The Solution: "Bring Your Own Phone" (BYOP) Workaround
The only way to use a different SIM card in this phone without returning to the store of purchase is to treat the BLU phone as an unlocked/third-party device rather than a Tracfone-branded device. [1]
You can attempt the following process to get service on the device:
Purchase a Universal SIM Kit: Buy a generic Tracfone Bring Your Own Phone (BYOP) SIM Kit (typically available at stores like Best Buy or Walmart for around $5). [1, 2]
Select the BYOP Activation Route: When you go to the Tracfone Activation Page, do not select "Activate a Tracfone Phone". Instead, choose the "Bring Your Own Phone" option. [1, 2, 3]
Register the SIM: Enter the SIM card number from your newly purchased kit. [1]
Bypass the IMEI Check: If the system asks for your phone's IMEI number, the system may flag it as "not scanned" or "not eligible". In many cases, selecting a T-Mobile-compatible SIM from the kit or stating you have an "unlocked GSM phone" will allow you to complete the online activation using only the new SIM card number. [1, 2, 3]
Important Compatibility Notes
Network Bands: Since it is an older 4G BLU device, ensure the network provider you choose still actively supports your specific phone's 4G LTE bands. Most carriers require VoLTE (Voice over LTE) compatibility to complete calls.
Legitimate Proof of Purchase: If the phone cannot be activated online using the BYOP method, you will need to take the phone and its receipt back to the retailer where it was bought so customer service can manually scan the barcode and release the IMEI lock.
This procedure may not fix it. Has charger and in great shape
