Getting an NUC but keeping sim

[azougon]

If I get an NUC for my current phone (Pixel 3), to test a sim from another network for a family member, will I be able to go back to my current Vodafone sim afterwards.

Yes @azougon 

All the Nuc does is unlock your phone so that any network sim card works in it.

It does not affect your Vodafone sim card.

Hi @azougon

Vodafone cannot lock a Google device to the network try an alternate SIM in the phone. 

You would have been unlocking the phone not the SIM card.

Just to be absolutely clear, as I'm a belt and braces person, once I have unlocked my iPhone 4 I will be able to use it on 2 different networks by just swapping over the 2 sim cards?

That's right @Dapper - once you have used your Network Unlock Code (NUC) for your phone you'd be able to use any and every SIM that you'd like.
