Unlocked from new Xperia Z3 - does it lock to 1st sim/network used?

[diggergraves]

Hi.  Sorry if this has been asked / answered in the past but will my unlocked from new Xperia Z3 now be locked to the 1st sim/network I used with the phone, Tesco Mobile / O2 in my case, or will any new sim from a different network work ok?  Thanks in advance for any answers / replies.

If the phone it's SIM free it won't lock, if the phone is network locked/SIM locked, then you will have to unlock it and then you can switch as many SIM cards from different networks as you want.

Thanks uliwooly.  Yes the phone was bought new from Argos unlocked with no network and I currently have a sim only deal to use with the phone so I guess from your answer because it was unlocked from purchase I can swap and change sims / networks at any time with no need to unlock and the phone doesn't lock to the 1st network used as some other phones do.

That's correct.
