I have an application that texts various phone numbers, mostly 027*, 027100* and 021*, that had been working fine but recently started failing when texting 027100* numbers. I suspect a change was made to one or other mobile network sometime between 6am May 23 and 6am May 24. When a mobile with an 027 number is used to query a 027100* number, the correct reponse is recieved. I have someone looking in to this problem from the 027100* side of things but progress is slow.
Can someone check this problem is not being caused from the Vodafone side of things?
