Blocking Orange

[G4GVB]

Any one know how I can block Orange from text messaging me, or even block Orange altogether. I have had them turn off all their ad rubbish, but they still text me about Magic numbers.
Or
Maybe an app that only lets texts from my contacts come through.

I wouldn't advise blocking, as Orange send configuration info via SMS/MMS - my APNs were updated last week due to T-Mobile's data network becoming available.
