I just bought a go phone, will it work as a normal cingular phone if i

Ya sure the new brought go phone will freely work with your cingular sim card only if the phone is unlocked one else if the phone is locked to some other network provider then it wont accept any other GSM sim until you unlock it ...You can easily unlock the phone through online providers like SuperUnlockCodes.com for reliable cost .You first check that whether the code is available for your phone model ,country and network provider .If yes then pay for it and unlock the phone then freely use it with any GSM sim ...
