Thankfully my mom has not yet had to summon help for any reason, so I can't speak of the co's service when that need arises, but I can say that during my research period when I was trying to choose a medical alert service for my mom, I found MobileHelp's staff to be the kindest and most helpful on the phone. Their customer service was excellent. And that continued through the setup process after I opened the account. Every single person I have spoken to on the phone, has been professional and helpful. In this day and age, that is often the one thing that tips the scale for me when choosing anything. I would highly recommend their service. And by the way, I called them in the first place because a friend has been using their service for years and gave me the same sterling review of their customer service. So I'm paying it forward. They deserve it.
