Hi, Is there a lock switch on card? If so switch OFF to unlock. Also try removing batteries for 30minutes. Then try again. Be aware that most memory numbers could be erased. You may have to reprogram the numbers in again. Good luck.

Understand the meaning of unlocking a mobile If you put another simcard into your Samsung A197 phone and it does not allow you make calls with it, then your Samsung A197 is simlocked. If your A197 phone is "simlocked" when you put an alternative network simcard in your phone it could show "enter correct sim", "enter subsidy password", "wrong sim", "incorrect sim" or similar. If you want to use your A197 phone with another simcard then you will need to unlock your phone. There are some small considerations you need to make sure before you start such as simcard compatibility and making sure that your phone is definately "locked" not "blocked" there is a distinct difference! Is your Samsung A197 Locked or Blocked? A locked Samsung A197 means that your Samsung A197 phone ONLY accepts simcard from the network it was purchased with. This is easy to solve, we can supply codes that can fully "unlock" your Samsung A197 phone to all networks. This means that your Samsung A197 phone can then be used on ANY chosen network in any compatible country, WORLDWIDE. Alternatively a Blocked phone is a phone that has been reported lost or stolen, and has been blocked by the network for use. These phones are unusable and there is no way around this. Unblocking a phone is ILLEGAL and we offer no service for this.

it needs to be unlocked, the phone is locked in some network and it will not allow you to use another simcard or if is a 128k simcard it will not allow 64K simcard

Open and remove the battery. Replace battery and close. Hit the Power button

If you Unlock the phone for use with any sim card you will still have access to the android market regardless of the sim card you use
