The UK is one of the largest and most complex mobile messaging markets in the world. Many filters are in place to block different types of traffic and cheap SS7 routes are extremely unstable, even on a short-term basis. A direct connection is necessary in order to ensure high delivery levels and a good price-quality ratio. Nexmo is using a direct connection to all UK networks!
This direct connection is fully featured including handset delivery receipts, dynamic sender ID and delivery to ported numbers.
Note that this does not include Jersey or Guernsey. Incidentally, these routes are also direct connections and high levels of deliverability are ensured also!
T-Mobile are filtering Sender IDs containing some symbols, including _ and -
