Features & Capabilities

OneMail is the companion app for your OCENSMail account.

OneMail allows you to keep tabs on your OCENSMail account and any IMAP enabled 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 satellite phone 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.

User Reviews

This is an excellent app for low bandwidth satellite connectivity such as with Iridium Go and even with BGAN. Has several advantages over the native Iridium email app, including direct access to your email account for send and receive (no forwarding or separate email address required), faster fetch as it only gets headers initially, ability to work on regular internet connections as well as satellite, and many more. And the Ocens support team is excellent and responsive!

No glitches. Absolutely a more elegant solution than Iridium mail app. Must pay for the privilege.

The app works great. But a word of warning. It is necessary to go to your G-Mail account and approve third party apps, signing into your email. Also, if you don’t use your One Mail for awhile. It is necessary to go back in to your G-Mail to authorize it again. G-Mail has a feature that shuts it down automatically when it hasn’t been used. I always check on this while still in cell range. In case, I need to set it up again. I do go several months, when I don’t need this app.
