Pointing the iSavi and connecting to the internet can be done by anyone. You may control the terminal using the free iSavi voice app for your iPhone or Android smartphone, or simply log into the terminal’s web UI (user interface). Making a connection to the internet is a breeze. Once the terminal is online, anyone else within range can connect to it like any standard Wi-Fi hotspot. up to 11 simultaneous connections. You can also be on the phone and internet at the same time since the free app also turns a smartphone into a satellite phone.

iSavi Terminal Pointing

Connect to the iSavi Wi-Fi hotspot from your smart device and start the iSavi control app. The signal strength meter in the app and the visual and audible indicators on the terminal itself make pointing a breeze. When the signal strength is high enough, click on ‘Connect to the Network’ to use the phone, and “Connect Data” to use the Internet and instantly, you’ve turned the iSavi into a global WiFi hotspot with a 100 foot WiFi range for Internet and voice calling.

Internet Connectivity – A Global Wi-Fi Hotspot
Internet speeds can be comparable to cellular networks at up to 384Kbps download, and 240Kbps upload. There are no LAN ports on the terminal and connection is only through wireless (802.11 b/g/n). Connecting your smart device, tablet, or laptop is as easy as connecting to any Wi-Fi hotspot. The iSavi control app is used to initiate an internet data session. Once a data session has been started, any device (with the Wi-Fi password) may simply connect to the hotspot for full connectivity. You can check your session usage (in megabytes) with the iSavi app.

Voice Calling
The iSavi voice app gives your smartphone satellite phone number to make or receive calls from anyone. Here is information on making and receiving calls over the network. You can have multiple phones connected to the iSavi (all with the same phone number), but only one phone can be in use at any time. You can also give your phone a local phone number so anyone can call you without paying for an international call. Also, Ground Control’s voice service for the BGAN uses no data, so you’re only charged the per-minute phone rate, and only for outgoing calls since incoming calls are free.

SMS Texting
Existing SMS texting apps like iMessage on the iPhone operate over the iSavi connection. SMS texting is normally $0.50 per outgoing text and free incoming texts with all plans. The iSavi voice app also includes its own SMS messaging tool. You can send a free SMS message to your iSavi.

Existing iSatHub Service Ending

New activations for IsatHub service ended on August 31, 2020. Now, iSavi terminals may use BGAN service plans to connect to the Internet (with a BGAN SIM card).



How do I WiFi into the iSavi terminal?

You can select the iSavi terminal from the list of available WiFi networks from your wireless connect screen. The default WiFi name (aka SSID) AND password for the iSavi are both on the back of the terminal printed on the placard. The default WiFi password for the iSavi is different for each terminal. It is a 9 character length password that looks like 6801E392. You may change the WiFi password to something memorable from inside of the iSavi Control App or web interface (from a laptop). If you are connecting with a laptop, enter in into a browser to access the iSavi web interface. If you are using the iSavi App, you just need to turn it on (and enter the login “admin” and password “1234” or “123456” (without the quotes).

Voicemail - How do I setup and access my BGAN voicemail account?

The BGAN voice mail be accessed by calling 570 (short code) or 00-870-772001899 from a phone connected to your iSavi terminal (and using the Voice App), or by dialing 011-870-772001899 from any other phone (at least from the U.S.). Here are instructions for making and receiving calls with iSavi. When prompted by the voicemail auto-attendant, you will be asked for your iSatHub phone number, as well as the VoiceMail PIN number supplied by Ground Control. Here are detailed Instructions on setting up your Inmarsat Voicemail.

What is the operating / stand-by time?

The standby time of the iSavi is currently advertised at 24 hours with the new firmware improvements. On a fully charged battery, and transmitting continuously (such as streaming live video), transmit time is 2.5 hours using the standard 3 Amp hour battery. A long life high-capacity 6 Amp hour battery is planned to shortly after launch.

Can the iSavi be placed in heavy rain?

Although the manufacturer states the iSavi has an environmental IP (water ingress) rating of IP65, we recommend placing the terminal inside of a large ziplock baggie during any rain.

Who do I buy my service from?

Ground Control. If there is anything you require, we are your single point of contact. Inmarsat does not sell direct to the public.

What is the WiFi range?

The integrated 802.11 b/g/n WiFi access point is capable of connecting devices up to a range of 30 meters (100 feet) from the terminal. However the user experience may vary depending on physical conditions (walls, etc) as well as the capability of the WiFi in each connected device. Note the default setting of the iSavi is 802.11 b. If you wish to use the “g” or “n” frequencies, they can be added from the web interface ( under the WiFi settings.

Can the WiFi channel be changed if the iSavi WiFi network is not at full strength?

Yes. Default is “Auto”, which means the iSavi will select the best channel on startup. You may manually select a different broadcast channel from the WiFi settings inside of the web interface ( under the WiFi settings. More information on this can be found in the iSavi Users Manual.

Can I configure which 802.11 b/g/n wireless frequencies are transmitting?

Yes. Default is 802.11b. You may select 802.11 b or b/g or b/g/n frequencies from the iSavi web interface ( from the WiFi settings tab.

Are SD cards supported?

SD cards are not supported.

What data speeds is the IsatHub service capable of?

IsatHub supports background IP with speeds of up to 384 Kbps download speed and 240Kbps upload speeds.

What Apps are currently available for the iSavi?

Inmarsat offers two Apps for accessing the iSavi: The IsatHub Control App for pointing, connecting and usage meter and device controls, and 2). The IsatHub Voice App to enable voice calling and text messaging. Both apps are available in Apple iOS and Android versions. Both are available to download free of charge from the Apple App Store and Google Play.

Can more than one smart device connect to one terminal?

Yes, via the WiFi hotspot which may be password protected. Multiple devices may be connected at the same time but the speed of the connection will become less useful as the number of simultaneous users goes up. We expect a good user experience for up to 4 simultaneous users in most conditions.

Do I pay Roaming Charges for making a call from anywhere?

No. One bright feature to the international phone number provided by Inmarsat’s BGAN service is that there will be no roaming charges for placing calls, therefore, the cost of using the iSavi can be significantly less than using your 3G/4G mobile phone or tablet when roaming away from your home area. The cost of making a call is the same no matter where you are.

How many voice calls can be made simultaneously?

One. Using the voice app, only one voice call can be made at once, as there is only one circuit switched channel per terminal.

If more than one phone is connected, and there is an incoming voice call, which phone will ring?

All phones connected using the voice app will ring and the first to answer will be connected.

If more than one phone is connected, which can send or receive text messages?

Only the phone connected as control app administrator can receive or send texts, at least with the IsatHub Voice App SMS texting screen. Texts can be sent also from Web MMI if a user has admin credentials. Other SMS texting apps like iMessage will operate with current OS software.

Will a VoIP app work over the background IP connection?

If a user wants to use an end to end VoIP app, then the voice quality cannot be guaranteed as it will be over a best effort traffic connection. However, it is worth noting that some VoIP apps, including Skype, can be very data intensive and so may not work very well over the Internet connection and may result in higher anticipated use. It is for this reason that we recommend using the voice app to ensure high quality voice calls (this is a circuit switched PSTN “public telephone” service ).

Will IsatHub work with smart phone apps?

All Internet messaging apps for smart devices should work. However some settings may not be optimum for a satellite connection.

How will IsatHub manage background applications that connect to the Internet?

IsatHub is making use of a firewall to prevent too much data consumption in the background. However this will not prevent high volumes of data being sent in all cases.

How can subscribers manage their data usage levels?

Subscribers may track their usage via the usage counters that are available in the control app. This includes the ability for a usage limit or time limit to be set by the user themselves. In addition, it may be possible to set some apps to non-push mode to reduce the amount of data that is sent.

Does the control app provide visibility of data usage for each smart device connected?

Yes, the control app has counters for each device connected to the WiFi LAN as well as a global counter. If the user sets a data limit, the counters will be reset. If no data limit is set the user may manually reset the counters.

In the control app, what does administrator rights allow?

Administrator rights allow the subscriber to set the firewall settings and the WiFi password. If the person in the field is not the administrator, then they will only be able to select from the settings that have been preconfigured by the administrator. In most cases, the administrator, field operative and bill payer will all be the same person but it might be the case that they are separate entities, in which case it is recommended that there is only one person with administrator rights.
