Ongoing Costs: Prepaid Airtime Plans

If you’re a seasonal or occasional user, prepaid airtime is the most flexible and predictable option. You purchase a block of airtime credits, which you can use for calls, SMS, or data.

Here’s what Inmarsat prepaid pricing looks like in 2025:

Usage Conversion (approx.):

• 1 unit ≈ 1.3 voice minutes to landlines/mobiles
• 1 SMS ≈ 0.5 units

💡 Key Benefits: No monthly bills, great for infrequent use, easy top-ups.

⚠️ Watch out: Unused credits expire at the end of the validity period, so buy only what you need.

Ongoing Costs: Postpaid Monthly Plans

If you’ll be using your Inmarsat phone regularly or year-round, postpaid plans can be more economical.

Typical 2025 postpaid plans from major resellers:

💡 Key Benefits: Continuous service, lower per-minute rates, convenient billing.

⚠️ Things to consider: Early termination fees often apply, and you’ll pay whether or not you use the minutes.

Beyond the phone and airtime, here are optional but common expenses that affect your total budget:

• Spare Batteries: $90–$120
• Solar or Vehicle Chargers: $60–$100
• Protective Case or Pelican Box: $40–$80
• External Antenna or Docking Kit: $200–$500

These accessories can be invaluable if you’re operating in rugged environments or away from power sources for long periods.

Rent vs Buy: Which Is More Cost-Effective?

If you only need a satellite phone for a short expedition, sailing trip, or emergency standby, renting may save you hundreds.

Typical 2025 rental pricing for the Inmarsat IsatPhone 2:

✅ Best for: Short-term users, occasional travelers, backup communications
⚠️ Downside: You return the device, so no long-term asset ownership

Rule of thumb: If you’ll need it more than 3 months a year, buying is usually cheaper overall.
