"Code error" unlocking Nokia 6020b - Help please

I had tried the following codes from unlock code freeware but have received two "Code Error" message:

#pw+248275472664076+7#
#pw+235035472664076+7#

I connected a SIM card from another provider to get the "Enter restriction code" box. Otherwise without a SIM card, I get no messages after entering the code.

Thanks in advance for any assistance

Try this code only once and make sure it is entered correctly. Please let us know what the message was. If it says restrictions off, you will be given another code to complete the unlock.

 

Thanks! I guess it worked even when it displayed a Code Error. I was able to insert a sim from an another provider, so I assume it is unlocked now. Many thanks for your help.

 

Dont write noncense.If your phone can work with other provider,and you seen only-code error,-your phone was already unlocked before all those codes or was not locked at all.

 

why are you upset? I used the first code you gave me, which resulted in it displaying a Code Error. I then read in another forum that sometimes it is unlocked even if you get a code error msg. it suggested to try a different sim card to verify. i did that and it worked. i didn't need the second code that ended in +2.

you helped me and i said thanks. what is your problem with that?

 

I havent problem with that.
Simply,if you seen-code error-its possible,you neednot any codes.

 

Before I tried any codes, I inserted the another provider's sim and it said "Invalid Sim", that's why I looked online for a code.

 

Invalid sim?
Maybe,this was a problem?

 

Ah OK, I thought that "Invalid Sim" meant that the phone was locked. Anyways, thank you for all your help.

 

Thanks for the reply.
