OK VERY weird then....I just looked at my Company provided Torch, purchased on our corporate account with Bell through a Bell store.
Why would mine also say Security Disabled? I am the only user of this phone and know I have never had it unlocked.
also, it's in Options>Device>Advanced...>Sim Card ...just in case anyone new reads this and has trouble finding it.
When in that screen if you hold left shift and type MEPD, the field will expand, and you should see SIM Disabled, Network Disabled, Network Subset Disabled, Service Provider Disabled, Corporate Disabled.
