I have a Galaxy S3 running android version 4.3. I want to unlock it to give it to my daughter. I have tried *#197328640# but nothing happens. I have read that this code does not always work on version 4.3 software. Is there another way round this?
Welcome to the forums. You can try contacting your carrier to unlock the phone for your. What carrier is your S3 on and what carrier does your daughter have?
The phone is on o2 but it is an old work phone on a business account. I would have to go through too many managers to get it unlocked. I have got a SIM from the Carphone Warehouse which is their own ID network (based on Three). Its only £5 for a rolling 1 month contract which includes 1GB of data, 5000 texts and 250 minutes. I need to unlock the phone so I can use the SIM.
