Welcome to Vodafone Community
@pcheong Thanks for getting in touch, I'm sorry to hear your having trouble using your NUC. Have you tried the following instructions to get your Nokia unlocked:
1. Turn on the phone without any SIM
2. Enter the following sequence (#pw+NUC+1#) on your Nokia 150 just like a phone number
3. Press # at the end to confirm the code
4. Message "SIM restriction OFF" should appear
To generate the P you must press the star key quickly 3 times.
To generate the W you must press the star key quickly 4 times.
To generate the + you must press the star key quickly 2 times.
Unlock codes are 15 digits long.
For example if your NUC is: 987654321012345 you would enter: #pw+987654321012345+1#
Let us know if this help, if not feel free to pop back to us and we'll be happy to investigate further 😊
