I dont know the phone lock code but if i put old 1 sim it works


The lock does not appear to be on the phone as the old SIM works. The lock is in the new SIM. You have to call the phone company or if you have the PUK code for the SIM you can go to the phone company's website and check how you can unlock the SIM card.

'sim card not valid' when i do insert my sim card.what might be the problem ?


Hi,
Your phone may be locked to its Network, that's why it shows "sim card not valid". In order to use other Networks, you need to unlock your phone. You can unlock your Nokia N70 using code.You can either get the unlock code from your service provider or from reliable online site. Superunlockcodes.com is where i unlocked my phone, they offered codes at affordable price, with simple unlocking instructions.

My samsung s8300 phone is locked to orange, i tried to unlock the phone to o2. I then ended up putting in the simcard pin code wrong 3 times and it froze the phone. When i put 02 sim card in it says PHONE...


If the phone displays the message "PHONE FREEZE. SIM UNAVAILABLE PLEASE CONTACT YOUR SERVICE PROVIDER" then your phone has got hard locked. You need to unfreeze the phone to get unlocked. You can get the unfreeze code, unlock code through online..........give your IMEI number and get the unlock code for ur mobile.... i will suggest the website TheUnlockSpot.com which is doing good service .....you can approach this website.

Hi I Cant Find A Free Sim Unlock Code For A Samsung Sgh J700i Could You Help Me?


1- Power on phone, type : *#7465625#
you will identify which code is active , which is inactive

2- Remove battery, Put your sim card, not all of it, just to prepared for it to be full inserted, put your battery back and power on phone, you must see " insert sim" not "invalid sim.."

3- type : *2767*3855#
your phone should restart after 1 min,
now, and before it restarts, push your sim card in, without removing battery.

4- your fone should work and accept the sim card ,, but if you chek locks you will find that your fone is still Loked

5- now type : *7465685*638*00000000*00000000#

How do i unlock my sim card to use it in a new


Mobile phone manufacturers make GSM phones with a SIM lock, a built-in capability to restrict the use of these phones to specific countries and network providers. In this way, phones can be locked to only accept SIM cards from a specific country, network or service provider, or only a particular SIM type. In fact, most mobile phones are shipped with country and network provider locks these days. Unlock SIM card. It is now either mandatory or voluntary for the provider to unlock the SIM card of the customer. Still, some providers are reluctant on doing it even after a customer has fulfilled their service contract. A few others will unlock the SIM card of a customer only if he/she has an active account in good standing for at least 90 days. Some network providers charge a fee for releasing the unlock code. Unlocking laws vary from country to country. For example, in Belgium, networks are not allowed to sell locked handsets. In The Netherlands, providers must provide unlocking codes, but are permitted to charge a fee for this during the first 12 months after purchase. The Hong Kong government does not allow networks to sell locked mobile phones, though the restriction does not apply to some PDA phone models, such as those offered by BlackBerry. In the US, unlocking is now legal. Unlock SIM card and special codes. You can unlock a handset by entering a special code, or in some cases, over-the-air by the carrier. In most cases, a locked phone will display a message if a restricted SIM is used, asking for the unlock code. The code needed for removing all SIM locks from a phone is called the master code or network code key. The phone itself verifies the unlock code, which is either stored in a database or calculated with the help of a complex mathematical formula supplied by the provider.
