Due to the following I find it interesting that you are still been able to receive Raymarine grib files.
“Dear Raymarine GRIB Weather Subscriber, Regretfully, Raymarine has made the decision to suspend our email-based GRIB weather subscription services as well as our on-demand GRIB weather services used with our RayTech RNS software. This change is effective immediately. There are many alternative sources for free and subscription-based GRIB weather available online. A quick search on any search engine using the terms “GRIB weather files” will reveal many possible sources to you. Subscribers to our satellite fishing maps email service for Sea Surface Temperature (SST) and Plankton data will continue to receive this data as-normal. If you have any questions, please do not hesitate to contact Raymarine Product Support through the “Ask Raymarine” portal at
Raymarine Marine Electronics - Support Home. Best Regards,The Raymarine Team.”
I am using now Ugrib, which work with Raymarine and other navigation software.
For weather fax see thread Are weather faxes worth the effort?
As I see it, the advantages of sat phone are: small footprint, low power consumption, and simple direct communication.
