Welcome to Vodafone Community
have received an nuc for my k5160 dongle but when i follow instructions to ulock it says email mailto:nucresolutions for an unlocking tool..
When i do this i get an email sending me back to the nuc request form, so am going round in circles as I already have the code !!
Please see the link here: How to use your Network Unlock Code
Although the dongle is not listed, if you choose Huawei R207, it should be the same process.
There are also a previous thread for unlocking a dongle here: https://forum.vodafone.co.uk/t5/Other-OS-Unlocking/Unlocking-a-mobile-WiFi-device/m-p/2605348#M66004
If you still have problems, please contact Vodafone through the Customer Service channels or come back to the forum.
just tried that...it jsut says i'm not connected to the internet...there's no ip address on the device itself and using the ip address mentioned in the instructions gives the above result. Have also tried the ip address i found using "My computer" but that does exactly the same. Does the new Sim have to be "Active" because if so that isn't the case, i've just put an old 3 sim in there which I haven't used for ages
