1. Insert an unacceptable SIM card to locked phone, now phone should ask unlock code (NP code?). Easy just enter code.
2. Not working?, alright now remove the SIM card and try this code ###825*09# . got the prompt for code? enter the code.
3. Failed above, try *983*8284# . It should work.
4. Try *983*865625# also it's working on few models of ZTE phones like F102 (Thank you 'Lomarko' for your comment)
5. For ZTE S302, TMN1200, MEGAFON SP09, EMPORIA V170 Life+ >> insert a SIM card and type ###3854#UNLOCK_CODE# . (Replace UNLOCK_CODE with unique unlock code for your phone)
6. ZTE VODAFONE ZTC SP50 >> insert a SIM card and type ###1562#UNLOCK_CODE# and after press GREEN KEY. (Replace UNLOCK_CODE with unique unlock code for your phone)

Hi,

Just put your sim card on another phone set to make it sure whether your SIM card is working properly or not. If yes, then do a factor default after saving your necessary data please.

You can often use the ZTE Free IMEI unlock calculator to unlock the ZTE devices. Click link below to check and please 'Thank' if I helped you.
