When you place a new or a existing SIM card from another phone provider into your mobile phone and it asks for a Security code then :- This phone is locked to the original mobile phone provider. You need to contact this mobile provider to ask for the unlock code (security code) for this phone. You need to provide proof of ownership etc and the phone's unique IMEI number which is located inside the phone under the battery. They use this number to generate the unlock code for your phone. They should provide you with instructions on how to enter this code into the phone. Once you unlock the phone, then you can insert a new SIM card in this phone or sign up with another phone provider using this phone.
You could ring the phone provider and ask for the unlock security code because you are going overseas and wish to use your phone with a prepaid SIM card from another country. This maybe a free service. The other way to get your phone unlock is to use a phone unlocking company on the Internet, they usually charge a couple of Dollars for their services.Use Google and search for "Security unlocking code” companies in your area. You can also try this WEB site :- http://www.mobileunlockguide.com/mobile-phone/ www.unlock-free.com/nokia-master The IMEI number is unique the each mobile phone. The number is printed on the label under the battery. You can also get the IMEI number by entering this on your phone *#06# It will then display your IMEI number and you may also get a unique global serial number. Your IMEI number should be 15 digits.
I have just tried it with my new locked to orange g600 and it works fine on all networks.
1-Turn on the phone without sim card . 2-Pull off the battery cover and insert any non-accepted sim card (without turning off the handset) 3-Do full reset *2767*3855# , phone will reboot and goes to Menu . 4-Customize Sp-lock code *7465625*638*00000000*00000000# 5-Unlock your phone with new SP code #7465625*638*00000000# 6-Enjoy G600 unlocked if it doesn't work after step 3.. try changing the 'non-accepted' sim card that ur putting in.. eg if you are locked to vodafone and you try this method and use an orange sim card and it doesn't work, try using a o2 sim or even virgin :) its easygood luck
Had the same problem, phone just seemed to be cut off, tried updating the Sim off the Orange site, but phone was too old for it to update. Phoned Orange explained the problem, and they very kindly sent me a new Sim card, free of charge, I could also keep my old number and credit that I had on my phone, and they even supplied a free phone number to register the Sim when I received it. Apparently the Sim card was faulty even though I had, had the card 11 years with no problem whatsoever, strange that it if fine one day then 'faulty' the next, still hat's off to Orange for quickly rectifiying the problem for me. Phone Orange on 07973100 450 give your phone number but not your 4 digit code, then wait to speak to an person/advisor.
Yes. Just buy a pay as you go sim card and pop it in the phone but if you buy as sim from another network you may need to get the phone unlocked. What I mean is, if you are on Orange, for example, you will be able to use an Orange pay as you go sim but if the new sim is from T-Mobile you might need to get your phone unlocked
