I ran across this on a MetroPCS board, but noticed they also list Virgin Mobile. MX Telecom is a company providing SMS and MMS Gateway services, and they have an online System Status board that reports outages and planned maintenance from companies they contract with, including VM. It may be useful for those wondering about SMS/MMS outages that occur at times.
