hi 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 you are allowed 5 free attempts to unlock the phone, if all 3 dont work then do not try any of the others, sorry but i cannot unlock it and you will need to take it to a shop for a cable unlock Model: Nokia (6230 ) IMEI: 356645009136252 Network: 23430000 #pw+223 025 246 112 734+1# #pw+986 832 603 400 347+2# #pw+383 496 601 116 104+3# #pw+183 434 005 176 244+4# #pw+947 262 662 574 677+5# #pw+858 001 373 602 011+6# #pw+356 396 775 455 206+7#
