Contact(s) not receiving SMS

[NeilJ99]

Hi,

It has come to my attention that at least one contact is not receiving any SMSs sent from my number.

I have sent one to myself as a test and I received it.

Please help.

Ask the contact if he has blocked your number in error. That's the usual reason for this happening.

I will do.

However, I also sent an SMS in reply to a new 'caller' and never received a reply from them either. I don't know whether they received it or not.

EDIT: The original contact is able to message me.

Neil.
