Can’t send sms

[Lornas7141]

So can no longer send sms messages I could up till a week ago then just stopped working. I have an iPhone the green line goes across half way then stops and just says “not delivered” any solutions?

Was there some software update or settings changes since it was working ok? 

Anything useful here?

Could iMessage need to be activated again for some reason? 

If so then you would need to put some cash credit on your account (e.g. €1) to cover the cost of the UK SMS that the phone silently sends to a UK activation server. 

If you need to contact 48 support about this then see the links in my signature below.
