I spent a lot of time researching the best companies for this incredibly important service. In all, I interviewed six companies. MobileHelp did not put the hard sell on me, they called back when they promised, and did not spend our time bashing the competition. Since I have had the service (two months), they have done and been everything they said they would be. They are thorough and easy to understand. I have tested my device once each month and both times went smoothly. It is comforting that they tell me exactly where I am! Both operators were nice and easy to understand. This service has been a God-send for my recovery and confidence from a totally unexpected heart attack.
