      It just works as expected within minutes -- you get both outbound/inbound messages, with delivery receipts or incoming callbacks -- all working in the easiest form.

      Twilio is by far the most complete solution for SMS, its API is extremely well structured. And its integration with rails is pretty straight forward.

      We fall back to Nexmo when Chikka (https://api.chikka.com) and Semaphore (http://semaphore.co) have downtime or deliverability problems. Chikka and Semaphore are local (Philippine) SMS APIs handled by SMART and Globe, respectively, and report higher deliverability rates than Nexmo (at lower cost).

      We use Twilio extensively for voice call routing, for texting. We, in fact, use it for MMS messaging as of recently...We do number masking. So the personal shopper never has your actual number, you call the Twilio number and it routes you intelligently to the customer. And vice-versa.

      Twilio is a service I have experimented with, and given a project with SMS requirements I would choose Twilio to support that.
