If I am using my phone then isn’t it unlocked? Okay I will check to be sure.
A “locked” phone means you can only use the SIM card that’s in there now. If you try a different SIM card, it will not work. An “unlocked” phone means you can use any SIM card that fits.
Call your carrier, and ask them to unlock your phone, or how you can unlock it. Sometimes they can do it, other times you may need to download an app. It all depends on the carrier.
As far as the Old Bay – my wife just returned from the states, and she forgot to pick up more. I use it on everything – fish, chicken, vegetables, rice, tuna patties . . . Not having more will put a crimp in my cooking.
