Operating Instructions
After inserting the unlocking card and your SIM, the phone should attempt to unlock directly. Follow any on-screen prompts that may appear.
- Initial Unlock Attempt: The device is designed for "Plug-unlock directly." This means upon powering on, the phone should recognize the unlocking card and attempt to bypass the carrier lock.
- ICCID Update (If Needed): If the initial unlock attempt is unsuccessful, you may need to update the ICCID number. This process typically involves navigating through specific menus that appear on your phone after inserting the unlocking card. Refer to online resources or support forums for detailed steps on updating ICCID for your specific Phone model and carrier.
Troubleshooting
- "No Service" or "Invalid SIM" Error:
- Ensure the unlocking card and your SIM card are correctly seated in the SIM tray.
- Restart your Phone.
- Verify that you know your phone's original carrier. Incorrect carrier information can prevent unlocking.
- Attempt to update the ICCID number as described in the Operating Instructions.
- Phone Not Recognizing Unlocking Card:
- Check for any physical damage to the unlocking card.
- Ensure the SIM tray is fully and correctly inserted into the phone.
- Unlocking Process Fails Repeatedly:
- Confirm your Phone model is listed as compatible (Phone 11/12/13/ProMax/XR).
- Seek assistance from online communities or the seller if the issue persists.
