Cell phone tracking

I have read all of the inputs to your question on phone location apps. We have find my friend on our phones, as do some of you. What do you do when you have no signal at all. We just finished a trip 97 days on the road from Virginia to the Arctic Circle and back home. One of our safety items we carry at all times is “SPOT” Satellite GPS Messenger. We send out a Spot message each night to family & friends (Limited to 10 email accounts) giving them our exact location latitude & longitude and a short message letting them know we are all right. If they do not here from us in 2 or 3 days they know we are in trouble or something has happened. The device can also send out a help signal, need assistance, or an SOS. For life-threatening or other critical situations, it alerts the GEOS International Emergency Rescue Coordination Center (IERCC). GEOS notifies the appropriate emergency responder based on your location and personal information which may include police, highway patrol, the Coast Guard and others. Locations show up on Google Maps, pin pointing your exact location. No cell towers needed, the satellite is always there & reliable. We send out the spot message every night even if we are in the same location for more than one night. It gives us peace of mind and keeps our loved ones apprized of our location. I highly recommend this device for safety reasons… Dave & Holly Fox “The Tardis Time Travelers”
