In my case I thought it was worth an extra $100.00 dollars to get the LTE version. I’m aboard small (under 12 metre ) boats regularly and used to take my phone with me. The problem was keeping the phone dry. Now I just take the watch. Have also found that I am leaving the phone at home more often when I’m only out for a short time. Ive made and received some calls using it. Does what it says on the box.
If you use apple music, the next update of watch OS should to support streaming directly to the watch.
Telstra offers a 3 month trial of one number, then its $5 per month. My phone was out of contract, was able to negotiate a $10 discount on re-contracting anyway.
