The satellite phone has transformed long-distance sailing. Our bluewater cruising forebears would likely be stunned by the ability of modern sailors to download accurate weather forecasts, call anyone in the world and send back videos and images from mid-ocean, all from a tiny device.

There are numerous companies out there offering connectivity at varying cost and global coverage.

Buying a satellite phone is, of course, just the start – you’ll also need a SIM card and data plan. These vary considerably in cost and it’s worth spending some time researching the best options for your type of sailing. MailASail have a useful guide to choosing your usage on their website.

Questions to ask before buying a satellite phone

  • What will you be using the phone for, primarily? Weather forecasts? Voice calling? SMS? Emergencies only? These will have a bearing on the type of device (see below) and the type of contract/pre-pay deal you end up with.
  • Do you need it to have an SOS function, or are you happy with a separate EPIRB, for instance?
  • Do you need waterproofing? some of the latest satellite phones are waterproof to IP67, but some older models must be kept dry – an important consideration.
  • How important is battery life? If you’ll be mainly using the phone on board with ready access to charging, you may not be as concerned as if you were planning to use the phone in an open boat, for instance – it’s worth a careful look at battery specification.
  • Do you need internal GPS? Satellite phones with internal GPS can offer significant peace of mind to family and friends ashore, but this comes with a cost, both financial and to battery life.

Let’s take a look at a sample of the best satellite phones for cruisers available today, varying in functionality and price from basic messaging to fully featured phones.
