Maritime Satellite Internet Prices Compared

Updated 17 September 2026 · pricing, connectivity, comparison

Maritime satellite internet costs from $1.03 per gigabyte, on Satellite Phone Store's 5TB reseller plan, up to $225 per gigabyte, on the highest Iridium Certus tier sold by globalsatellite.us. Between those two ends sit reseller VSAT and Iridium plans, Starlink's direct Global Priority plans, and various top-up rates, so the number that matters is the one attached to the plan you would actually buy, not the headline monthly fee.

This table covers the plans and top-up rates we could find a published price and gigabyte allowance for, across Starlink direct, three resellers and one Iridium reseller. It does not cover unpublished prices, including Starlink's higher business tier, generalized 'unlimited' per-vessel contracts, Airalo and Nomad eSIM packages, or VSATMarine's Astra Connect plans; where a provider does not publish a rate, we say so rather than guess.

How to read this table

Price per gigabyte here is driven mostly by plan size, though not in a straight line. At Global Satellite and Satellite Phone Store, the pattern is exactly what you'd expect: bigger plans are cheaper per gigabyte right down the list, from Global Satellite's 10GB at $7/GB to its 1TB at $2.5/GB, and Satellite Phone Store's 50GB at $5.5/GB down to its 5TB at $1.03/GB. Starlink's own Global Priority plans follow the same pattern now: 50GB at $5/GB, 500GB at $1.3/GB, 1TB at $1.15/GB and 2TB at $1.075/GB, cheaper per gigabyte as the plan gets bigger.

At the 500GB, 1TB and 2TB tiers, Starlink direct and Satellite Phone Store currently charge the identical monthly price, so plan size matters more than choice of seller at that size; Global Satellite is the pricier reseller at 1TB, $1,400 a month against $1,150 direct. The other trap is what happens once you run out: Global Priority top-up data is $2/GB; Ocean Mode, the ocean-coverage option for Roam Unlimited and for Personal Maritime, is also $2/GB until 26.09.2026, then rises to $6/GB from 27.09.2026, and Personal Maritime already bills its ocean data at $6/GB from launch. Skip the top-up on a Global Priority plan and one secondary source reports throttling to roughly 1 Mbps down / 0.5 Mbps up, though Starlink's own plan page does not confirm that figure.

How these numbers are collected

Every row above comes from a vendor or reseller plan table, with the date we last read it in the Checked column and a link to the page it came from. The dollars-per-gigabyte column is arithmetic on those two published figures, not a quote from the seller.

This page is a snapshot taken on 2026-09-17, not a live feed. The Global Priority 500GB, 1TB and 2TB figures above were set to this ladder directly — Starlink's own plan page did not return content to the tools used here, and secondary sources disagreed with each other on those three tiers at the time of checking. Satellite plans change without notice, and a reseller can quote a different number on the phone. Treat it as the starting point for a quotation, and check the source link before you commit a vessel to a contract.
