Welcome to Vodafone Community
Hi, I've got a Galaxy S7, which was locked to Vodaphone and want to be able to use it instead of my MotoG which is on another Netwrok.
My problem started when I installed the EE SIM into the Samsung S7, and it asked for the "SIM network PIN". As a novice I assumed this was the SIM PIN supplied by EE on the SIM Card. However, as I found to my cost, it was asking for Network Unlock Code (NUC), as the phone was locked to Vodaphone. But due to attempting to enter the WRONG SIM PIN too many times, it is now asking for the "SIM network PUK".
'Direct Unlocks', requested the unlock codes from Vodaphone and have sent me both:
1. Network Unlock Code & 2. Defreeze Code
However, when I power up the Samsung S7, it comes up with the following prompt:
"SIM network PIN blocked. Enter SIM network PUK"
I have tried entering both the NUC and the Defreeze codes at this prompt, but both result in the following response on the Samsung S7, "Network Unlock Request Unsuccesful".
I can see that other people have had the same issue, and a 'Moderator' seems to be of great help!!
Can you advise...thanks!!
Solved! Go to best answer.
