Sim card

I have given given daughter #1 my old iPhone. I requested for the old phone to be unlocked and she has been asking me every day when she can transfer her sim card. I finally received an email today to say that it is now unlocked. She moved the sim card from
her old phone but it doesn't work. I guess this will probably involve a trip to the orange store.
I wasn't feeling well today so didn't go to work.
The girls went kayaking and hubby went to pick them up at 7.45. When they got home, daughter #2 realised that she'd left her bag at the club house so they had to go all the way back.
