No outages, no dips in speed.
Voice quality is also excellent with no problems.
I previously had Earthlink DSL through Verizon. I signed up for Sprint ION xt2 package at the online form on Wednesday, March 14th. She was extremely friendly and went over all the necessary points of the service. She confirmed an install date of Thursday, April 26th. Bobby asked me to call back a few days after Verizon finished the NID to confirm my instal date.
