Garmin & ZOLEO are modelled as pausable; SPOT Flex is pro‑rated, SPOT Basic annual is not. ZOLEO has no photo/audio media and a 3‑month minimum term (so at least 3 paid months are counted); SPOT is tracking‑only. All Garmin plans (incl. Enabled) can be suspended free off‑season, so they’re averaged across active months only.

Assumptions & notes

  • Media (photos & audio): Only the Garmin inReach Messenger Plus and inReach Mini 3 Plus support sending photo messages and audio/voice notes. If you request any media above, only these media‑capable Garmin devices will be recommended.
  • Garmin inReach plans include Enabled (PAYG), Essential, Standard and Premium. Enabled is a low‑cost plan with unlimited SOS; other features are PAYG (texts £0.50 each; tracking points £0.10 each; photo/voice £1.00 each) at ≥10‑minute intervals. Essential/Standard/Premium include message buckets and (on higher tiers) unlimited tracking. All Garmin plans can now be suspended for free for up to 12 months at a time, with no reactivation fee — so off‑season months cost nothing and every plan is averaged the same way (base + usage × active months ÷ 12).
    Worth knowing: people often keep Enabled live all year (£7.99 × 12 = £95.88) purely to keep SOS active rather than suspending. If you’d suspend off‑season instead, you lose satellite/SOS cover in those months but pay £0.
    Activation: £39.99 (only payable again if a plan stays suspended for more than 12 months and is cancelled).
  • ZOLEO: Text‑only over satellite (no photo/audio media). Two plans:
    • Prepare — £17.99/month, 50 satellite messages (SMS, email, app‑to‑app, check‑ins, weather and Medical Assist all count), then £0.50 per extra message.
    • Protect — £29.99/month, unlimited satellite messages, check‑ins and Medical Assist (Fair Use Policy applies).
    Prepare works out cheaper up to around 74 messages a month; above that, Protect is the better buy. Both include SOS with 24/7 monitoring (SOS never counts towards your allowance), ZOLEO Track, and unlimited messages over Wi‑Fi/mobile data. Location Share+ (£4.50/month) is needed for breadcrumb tracking on either plan.
    Minimum term: 3 months on both plans. Pause: £4/month after the initial 3 months — note that SOS is not available while paused.
    Activation: £19.99 (one‑time; no fee to resume after a pause).
  • SPOT (Gen3/Gen4): Tracking‑only with preset outgoing messages (no two‑way texts; no photo/audio media). Annual Basic ~€14.95/mo ex‑VAT (+ Extreme tracking €5.95/mo). Shown only when you choose tracking‑only (no messages, no media). Flex pro‑rated; Basic annual is not.
    Activation: €29.95.
