In order to stay connected to one of the world's most reliable and far-reaching satellite networks, you need to ensure your IsatPhone is equipped with enough airtime credits. That's where IsatPhone Top-Ups come into play.

ISatPhone top-ups are suitable for IsatPhone Pro and IsatPhone 2. 

Useful Information

• Inmarsat SIM cards start with zero balance and validity.
• A top-up's validity period can be extended at a later date by purchasing another prepaid voucher or 30-day extension before the original top-up expires.
• If the validity period is not extended then your SIM card will expire and become unusable. Any remaining minutes will be lost.
• You can reactivate the SIM at any time by purchasing a new airtime voucher.

If you did not originally purchase your SIM card from Orbital SatCom, we won't be able to add credit to your card. However, Inmarsat SIM cards are free of charge so why not order a SIM card from us as well?
