Description
OneMail allows you to keep tabs on your regular email account when you are using limited bandwidth connections such a a satellite phone or slower 2g cellular networks that would normally make this impossible.
OneMail takes a very unconventional approach to checking your email account through slow or expensive connections. When you use OneMail to check your email, it auto-dials through your satellite link and then downloads the From, Subject and Size of the mails waiting for you in just seconds. It then auto-disconnects from your satphone so you aren’t burning unnecessary airtime while you review this summary information. Now that you are offline, scan down the OneMail list of waiting mail to see if any are of pressing or particular interest, swipe or tap on those messages to highlight them, then re-connect with OneMail. This time OneMail will access and quickly download those message before then once again auto-disconnecting. At your leisure you can now freely review the complete message and reply to those emails before reconnecting to send replies and/or look for new mail.
OneMail is completely private. Mail transfers are compressed and encrypted.
OneMail is compatible with the Iridium GO!, Iridium GO! exec, Iridium Certus and handhelds, Inmarsat and Globalstar handheld satellite phones, Globalstar SatFi, and the Sidekick family of satellite Wi-Fi routers.

★★★★★
One Mail has made it possible for me to stay connected while sailing across oceans. It's the only satellite email service that allows direct access to "your" email accounts (such as Gmail, etc.). It's made life a lot easier for us on board as it allows us to access our work emails without interruption - so it enables us to work remotely! Highly recommended!
★★☆☆☆
Doesn't disclose price or account required Have run out of time for now, but after 20 minutes I've discovered that the service costs $10/month which is not disclosed anywhere in the app or on the app page. You also need an OCENS account to make it work, and you can't create this account within the app. You can't even get to their website from within the app.
