After extensive research and making a spreadsheet with all the features & benefits of the top five life alert systems, I called MobileHelp with additional questions. My sales rep, Chris, patiently answered and explained the plan in detail. We are very thankful for this mobile alert system and within the first month my dad called for assistance. EMS was promptly dispatched and I was called. I also appreciate that he receives reminder calls when the unit needs to be charged. Customer Service has been consistently gracious when I've called with any questions or concerns. Thank you for peace of mind!
