Offshore weather at sea: ZOLEO vs inReach vs Iridium GO! vs Starlink

The cheapest way to get real GRIB weather offshore is a ZOLEO + Beamback: a $149 / €249 pocket messenger you may already own, plus €6/month, and wind, pressure, rain and waves beam back by satellite text, no phone signal. The classic Iridium GO! + PredictWind rig runs into four figures before your first forecast, and Starlink Mini's offshore Ocean Mode is capped and pricey. Here's the real cost, side by side.
