Size and functionality comparrison..
Sat phone - an 18 year old Motorola , it takes the sim from my normal mobile and can make iridium based sat calls / sms anywhere in the world but at scary prices. It was useful when negotiating retrievals of a rider with a broken neck in far nth NT , as well as a flail chest in the vic high country. Also great for checking the weather report from the francis peron peninsula in west oz, and keeping my wife updated whilst I crossed the simpson.
Mobile phone - samsung a30. Self explanatory, great for posting / watching video footage from my loungeroom but not much use for communicating if I fall over in the kitchen out of mobile range.
plb - $300 for 10 years, it sends an " oops at lat long" signal so someone who cares can hopefully come and look. Eventually. That might mean a 4 hour 4x4 drive for the local cop to check if it's worth sending helimed. I've waited for helimed with a flail chest and pneumothorax after dropping my motorbike putting it in the shed. It was a painful half hour and I really wasn't looking forward to decompressing my own lung if it progressed to a tension pneumothorax.
garmin inreach mini -$450 plus a monthly subscription that costs about the same as a cheap mobile plan. Sms style communication via sat network , plus tracking and emergency beacon facility. Great theory, but it misses tracking signals as often as it sends them. I should probably gave bought the larger model, but orefer not to carry huge useless things like mobile phones.
