The British Bullitt Group announced the Cat S75 and the Motorola Defy 2 intended for the American market, which is the same device, but with a different name, before the official start of the MWC. Both durable smartphones are capable of two-way satellite connection with the built-in MediaTek MT6825 chip (3GPP R17 NTN), and messages can be sent to iOS and Android smartphones via the Bullitt Satellite Messenger, the latter devices receive the text as SMS if Wi -They are on Fi or mobile network.

But what if there is no coverage? This is where Bullitt Group’s €119 (or £99/$) add-on comes in, the Motorola Defy Satellite Link. This is a small compared to a phone, a larger key ring size (70 x 50 x 11 mm, 70 grams) Bluetooth 5.1 accessory, through which iOS and Android phones that would otherwise not be able to carry out non-terrestrial network communication become capable of satellite connection. Satellite Link is capable of sending SOS signals, location sharing, and sending and receiving short text messages via satellites in geostationary orbit, since it also uses the same MT6825 NTN chip using the same 3GPP NTN open standard as in the phones mentioned above.
The Satellite Link is barely heavier or bigger than a keychain. [+]
With its physical buttons and LED indicator, Satellite Link can send an SOS signal and share GPS coordinates even without a connected smartphone, so it can be used even if the user’s mobile phone is dead or damaged. By definition, the Satellite Link cannot read or display incoming messages, it can only be used for one-way satellite communication without a telephone, so it can only be used to alert the emergency services. The built-in battery of the Satellite Link is 600 mAh, which according to the manufacturer lasts for four days, and the accessory is IP68 and MIL-STD-810H certified, so it can be said to be durable, resistant to dust, water and shocks. A phone with at least Android 10 or iOS 14 operating system is required for sending and receiving messages (maximum 140 bytes per message, Unicode). As you can see in the picture below, in the Bullitt software, the user can check how much data is left at any time, as this is subject to a subscription.
If there was an active subscription on the device, the user could see how many satellite data frames were left. [+]
In order for someone to use the add-on to send messages and call for help, a subscription is required. Admission is free, so if we want to write to our family about, say, a trip to the desert, all they have to do is download the Bullitt application to their phone. Bullitt’s solution uses the already active GEO constellations of Inmarsat and Echostar for communication, which means that it can take 20-30 seconds to send and receive a message. This is a bit slower than the LEO constellation emergency call used in the Apple iPhone 14, but the user does not need to hold their satellite communicator up to the sky while it finds a signal and sends or receives data.

According to Bullitt’s promise, Satellite Link will be available for purchase in the EU, UK, USA and Canada from the end of March and April 2023, and worldwide from the second half of the year. The €119 (or £99/$99) price doesn’t include a subscription, but €169 ($149/GBP) buys the hardware and a year’s worth of Essential Messaging, which lets you send 30 messages a month and includes SOS Assist service. SOS Assist is a FocusPoint International is provided by, maintains a 24-hour contact with emergency call centers every day of the week. The monthly fee for SOS Assist is a separate minimum of $5.
The 600 mAh battery can be charged via a USB-C connector, which is hidden by a small rubber door on the side of the device. [+]
According to the plans, we will be able to personally see during a demo on Tuesday how Bullitt’s satellite communication works on the products just presented.
