'How Do I Get a +44 Twilio Phone Number to Work?

I've got a client in the UK that I'm building an operating system for that requires messages going out and coming in from a Twilio phone number. I built it out on my account and got it working with my US phone number, however when I went to switch it to a UK phone number (+44 instead of +1) and tried sending myself a test message, my phone didn't receive anything. It didn't give any errors on the Twilio interface and asked if I received the message or not.

Any input would be greatly appreciated!
