Save my keister a few times. I have used this for a few years now and haven't had a single problem when my phones die and I need to pick up were I left off. In truth I forget it's there until I need it. Absolutely a must if you do any type of business via text like I do. I get a carbon copy of inbound and outbound text to my email account so I can print them for any problems that occurs and might end up in court. Set it and forget it. You will be glad one day.
