Inmarsat IsatPhone 2: what differences with IsatPhone Pro?



isatphone-2_productDesign and dimensions
IsatPhone 2’s design is very different from IsatPhone Pro’s. Black, with a rugged design while the former phone is blue and grey, it looks comfortable, elegant, modern and resistant. It is also much slimmer with the following dimensions: 169 x 75 x 29mm (antenna stowed) while the Isatphone Pro is build with larger dimensions: 170 x 54 x 39mm (antenna stowed). However, IsatPhone 2 is heavier than IsatPhone Pro with almost 40 grams extra, which makes it one of the heaviest among the latest satellite phones.

IsatPhone 2’s display offers large high-visibility. It is scratch-resistant and transreflective, which makes it easy to read even when the sun shines bright.




Like IsatPhone Pro, IsatPhone 2 can be used under extreme conditions: the operating temperature ranges from -20°C to +50°C for both phone and the humidity tolerance goes from 0 to 95%. However, IsatPhone 2 is marked as IP65 while IsatPhone Pro is IP54.


Battery life for both IsatPhone Pro and IsatPhone 2 in talking mode is 8 hours, while IsatPhone 2 standby mode is improved and reached to 160 hours while IsatPhone Pro can last 100 hours.

It is possible to use IsatPhone Pro charger on an IsatPhone 2 but this should only be used as an emergency measure. It might indeed speed up battery’s ageing.

Services and usability

Users will be satisfied to notice a much quicker registration on the Inmarsat network.

The general interface of the phone is the same as the IsatPhone Pro and is as easy to use. In addition, new options and features have been added to Isatphone 2 such as a programmable assistance button , a real “SOS” tracking button which offers you a new way of sharing your GPS position.

The IsatPhone 2 also allows you to be notified of incoming calls even when your antenna is stowed, although you need to unfold it to answer the call.


To conclude, IsatPhone 2 is a successful advanced version of the IsatPhone Pro which will satisfy user with a need for more resistance and efficiency.
