Message when re-satrting or powering on

[bushiee]

Sorry for miss spelling in title should be "re-starting"

My daughter and I both have galaxy a5's Mines the SM-A500F, Hers is the SM-A5000

Both are duel sim but only using single sim and memory card in the second slot.
Both running the lollipop update I'm on EE shes with TPO.
When ever she powers hers off or re-starts it she gets the following message
"Sim Card
When Changing SIM card, Data service slot also can be changed,When you want to Change Network mode, Please go to Mobile network menu and change it."
And it boots to the sim screen

first why is this popping up after a re-start or a power off/on
and second how do we stop it from appearing every time she re-starts or powers off/on.

Cheers

Here is the actual message

Just to update. I put my sim (ee) in my daughters phone and it does exactley the same thing. But her sim (tpo) in my phone and my phone boots normally.
So at least this means its not the sim its definately something to do with the phone
So if anybody has got anything I would appreciate it.
