How to check if a phone is locked to a network?

Hi guys,

Got a brand new Nokia c2 that was given to my wife by her old firm a year or 2 ago. I've got all the packaging and there's nothing to state if it's tied to a network.

Is there any way to check if it's locked? all our sims are micro or nano and this is a normal sim slot?

Kept this info. From memory these are universal Nokia codes:

IMEI number: * # 0 6 #
Software version: * # 0 0 0 0 #
Simlock info: * # 9 2 7 0 2 6 8 9 #
Enhanced Full Rate: * 3 3 7 0 # [ # 3 3 7 0 # off]
Half Rate: * 4 7 2 0 #
Provider lock status: #pw+1234567890+1
Network lock status #pw+1234567890+2
Provider lock status: #pw+1234567890+3
