This device relies on the Iridium satellite network and the real cost is not the device but the subscriptions. Having been using Iridium sat phones for fifteen years or so, I am impressed by the size of the device and the quality of the subscription and communication options. This of course is not a satellite phone but it serves many of the same communications and emergency functions. It has the ability to send texts, works well with the Garmin watch and with an iPhone and generally seems quite functional. It also is quite small. I think the design has been really well thought through. Why Iridium has yet to make a really small sat phone I don't quite get. But this device is small, easy to carry and functional. It's not for everyone and one should evaluate the monthly running cost when making a purchase decision but especially for someone who travels a lot to remote areas and/or is invested in the Garmin ecosystem this is something to very seriously consider
It seems sending and receiving SMSs with this device is not straight forward. Only a limited number of operators are supported. Check that your is supported before buying. I didn't check and complaints to Garmin never get a reply.
I bought a InReach Mini direct from Garmin. I was never able to register the device, activate it and hence purchase an Iridium plan. Garmin support in the UK were useless and wasted many hours of my time on the telephone and by email. I have rejected the product and I will be returning it to them for a refund. However i suspect I will need to obtain the refund via the my credit card company given the culture of Garmin seems to be to just fob off the customer and waste their time.
