How do i get sim unlock code

[Anonymous]

My father bought a phone at Asda due to needing larger buttons and wanted to put existing pay as you go sim into it.   However phone is locked to “pay monthly” sim which came with phone.

How do we go about getting the code to unlock phone as father does not need pay monthly charge of 10.00 he only has phone so we can get him in emergencies.  

Thanks

If it's locked to O2 the advice you need is here https://community.o2.co.uk/t5/Other-Products-and-Services/Unlocking-an-O2-phone-to-use-a-different-S...
If he is putting another O2 sim in there is no need to unlock it though.

If it's an Asda phone, it's most likely locked to EE though.

10. Mobile locking

Asda Mobile handsets are already unlocked, unless otherwise specified. Those handsets bought that are locked, you must not insert another operator’s SIM card into the Mobile without an unlocking code (which is not your PIN code). Asda Mobile cannot guarantee we will be able to provide you with an unlocking code for your locked Asda Mobile handset, as this is dependent upon the manufacturers. If we can provide you with an unlocking code, Asda Mobile will charge you a £15 fee to unlock the handset which will be deducted from your credit. Failure to enter the correct unlocking code may result in your Mobile becoming permanently blocked. We can accept no responsibility for Mobiles being blocked in this way. Contact the ASDA Mobile Helpline for further information on the qualifying period, applicable conditions and charges. This clause does not apply if you have purchased a SIM Only Pack or an unlocked Mobile and wish to use the SIM in another operators locked handset. If your screen shows "blocked", "barred" or "locked" then you will need to contact your previous operator for their unlocking codes.
