Not available from O2 unfortunately.
You need to look at sims from Tesco or giffgaff. Both use O2 network.
Hi there @EDAV
Welcome to the o2 Community forum
I understand your needs for parents.
True that o2 don't offer this anymore.
Have a search around giffgaff seems good they may offer this and they use o2.
Be aware that you may need to make a chargeable call every so often to keep the phone connected.
Good luck and best wishes TallTrees
