Will going back to factory settings network lock an unlocked BB Bold 9900

Hi, I've moved to a Galaxy S5, and also a different network, and now want to sell my old BB Bold 9900. To remove all data and apps on the BB I've done a reset back to factory settings. But I wonder will this also now lock the BB to a network again ? I had previously removed the network lock via the Vodafone help centre and it worked fine.

Also how can i check if it is network locked now without a SIM card - the card from my new network is a micro SIM and too small for the Bold ?

Thanks

No it should be still unlocked, try putting in the other sim from your new provider

Unlocked is unlocked forever. Once the software is modified there is no going back.
