How do i stop getting balance notifications after every text message?

[Arty4]

Every time i send a text i get a balance notification. This is annoying. Can someone tell me how to do it please? It is a new phone i am using as a help line so its not my usual i phone. It uses Android insteadbut i imagine thats not the problem.
