i presume your country is the UK, if not dont use them also there is a huge section just on unlocking 6230's Model: Nokia (6230 ) IMEI: 355038001872234 Network: 23410000 #pw+99 93 12 21 67 15 12 5+1# #pw+35 50 16 77 53 62 12 1+2# #pw+04 71 43 06 75 63 75 7+3# #pw+30 78 06 72 55 00 51 5+4# #pw+13 93 64 55 07 15 67 2+5# #pw+88 51 31 70 13 63 24 6+6# #pw+40 82 57 22 56 74 46 4+7# and this is how you do it Any one of the 7 codes codes will probably unlock your phone but I normally use Code 7 first, if that does not work then code 1 and on the rare occasion they both fail I try code 5. Now enter code 7 into your phone with NO sim card in! To access "p" just press "*" three times within one second. To access "w" press "*" four times within one second. To access button "+" you have to press twice "*" within less than a second. If successful you will see the message 'Phone restriction off' (if not you will get a 'code error' message). DO NOT TRY IT MORE THAN 3 TIMES [bold]i recommend you try it in this order, 7,1, then 5[/bold] HOWEVER do not try anything after version 5, just try it 3 times if they dont work sorry, but i will have left you two more free attempts, i suggest you take it to a shop for this if anything goes wrong i am not responsible however i do hope it works
