Message failed to send S8

[Bee]

I received an NHS message recurring a reply when I replied yes a pop up said I may need to pay for the message. I accidentally pressed the wrong icon and now I keep getting a no send message ! And no pop up asking me if I would pay . How can I undo this mistake ?

You could try clearing any cache files of the app and or clear the whole system caches files.

Try another texting app.

A last resort could be a back up and factory reset.
