Non-delivery is a non issue for us (Score 1)

I work for a media company in the UK and we do a VAST amount of SMS - primarily for user interaction with our shows. Non-delivery really is a non-issue for us - the main problem is time to delivery. In the past we could easily bring down several local cells if we put through enough SMS in a short enough time - and then we would have to wait for a fairly long time for the SMSCs to deliver them. We now have direct connections into the major Telco SMSCs here in the UK and have a VERY high throughput but even at peak times (Sat afternoon football matches, etc) our SMS delivery times are reduced.
