How do i find out which network my mobile phone is?

[Windows Central Question]

I have an old mobile but dont know the network its locked too.

It would be in your Phone's sim setup menu. Depending on which phone you have that will be different.

If you cant find that menu simply take it to your current carrier and ask them to see if it will be usable to their network. Instant answer will come as they try to set it up.

It's probably best to ask your carrier, as said above.
