I considered it but the online reviews don’t seem to be as favourable.
The InReach Mini also has GPS navigation options without needing a mobile phone (albeit that the mini is literally just a bearing to a pre-programmed waypoint). I see this as a good backup navigation option to give me a bearing & distance back to the car/civilisation if my primary GPS fails.
I also looked at the more traditional satellite phone which gives texting & often gives you a designated UK phone number but these were about double (or even triple) the cost for the monthly contract, so not really a cost effective option!
