02More about the top three

The ranking is above. Here is more about the three places at the top: what they are, why they are here, and what is worth knowing.

The three are not like for like: Apple and Pixel include SOS free for two years, Garmin adds a monthly plan, and the countries covered differ.

1Apple Watch Ultra 3

No. 1 — Apple Watch Ultra 3. On the lists of 2 of 2 AIs; median place there: 1.5. It ranks first because year one costs only the $799 watch, with satellite SOS and messaging free for two years.

Top 10 Watches That Can Call for Help With No Phone and No Signal: What the First Year Really Costs

2Why this topic

The reader gets one view of price, plan, coverage and tested battery for every watch that can call for help, where each source covers only one of these.

3Where it applies

Global: smartwatches with satellite or LTE emergency features from Garmin, Apple, Google and others

4What we looked at

  • First-year cost: watch price plus the plan needed for satellite or LTE features after any free trial
  • Whether emergency SOS works with no phone nearby
  • Whether two-way satellite messaging is included or costs extra
  • Battery life measured with satellite and LTE in use, not the claim on the box
  • Where the service actually works, by country and region
  • Apple Watch satellite guide — Apple's satellite features, the free period and where they work
  • Google Pixel Watch Satellite SOS help — Compatible models (LTE only) and the countries where satellite SOS works
  • Garmin inReach technology for watches — Satellite SOS and two-way messaging, the plan requirement and coverage limits
