“My phone does not prompt for a network unlock code.”
In this situation, it could be one of the following reasons:
– Phone is already unlocked
– Sim card slot is defective
– IMEI is blacklisted by the original carrier
– The phone requires an alternative way to unlock
If your device does not prompt for a code, please contact us for help to diagnose the problem.
“I input the code and received “Code Error” or “Sim Network Unlock Unsuccessful.”
In this case, you want to make sure you gave us the correct information pertaining to your device. Please check the following:
– IMEI when dialing *#06#
– Model number of the device
– Network the phone is locked to
If there are any discrepancies, contact us immediately with the correct information.
If all the information is correct, try the following troubleshooting steps:
– Check if your device has enough attempts left: Sony devices with 0 attempts left will still prompt for a code but will not unlock.
– Factory reset the phone: This will wipe the device but may fix the issue. Back up any important data from your phone before proceeding.
– Check to make sure your device is not rooted (ie. Custom ROMs/firmware installed): The device must be running stock ROM to accept the unlock code. Once it’s unlocked, you can root the phone again.
If you are still getting an error message, contact us for further assistance.
“I unlocked the phone but I’m not able to use data or send/receive MMS.”
In this case you will need to adjust what’s called the APN settings. The APN settings vary depending on the service provider you are trying to use. Please contact your service provider and they can assist you with setting this up. There is no separate unlock for data/internet or MMS. If you can call or text, your phone’s network is fully unlocked.
My Phone is asking for the “PUK” or “Security Pin” or “Password”:
If your phone is asking for one of the above, it is requesting a device or sim card passcode lock set on the phone by the user. Once you input this code, you will then be able to input the network unlock code provided by CellUnlocker.net
