Themis basically needs a M2M (Machine2Machine) SIM card, in order to avoid date issues
Install the SIM in the smartflex
Remove the smartflex from the Themis Box
Turn the router upside down. The SIM card slots are located on the back panel.
Themis without any SIM
It is possible to use Themis without SIM, but you may have difficulties related to time and date.
Indeed, for time management, linux systems typically synchronise with NTP (Network Time Protocol) servers.
Anyway, when booting a Themis machine without connecting it to a network linked to a NTP server, it is possible to manually set time on Themis
Once logged with a desktop machine to the Themis network (using wifi or wired connection through an RJ45 cable), the Themis server can be usually reached on 192.168.2.2.
You will need to establish a SSH connection
- on linux via the basic shell command
ssh pi@192.168.2.2 - on windows 10 via the Putty software (which is a simple exe file).
Just download the zip, unzip, drop the exe file on the desktop for example and launch it.
fix geographic area and time zone
Choose Europe for Geographic area and Paris for Time zone
sudo raspi-config
Localisation Options » Change Timezone » Europe » Paris
Current default time zone: 'Europe/Paris'
Local time is now: Sat Dec 16 19:57:26 CET 2017.
Universal Time is now: Sat Dec 16 18:57:26 UTC 2017.

sudo date MMDDhhmmYY.ss
using a local NTP server
We assume you know the address of a NTP server that can be reached by Themis, eg ntp.as.i2
sudo nano /etc/systemd/timesyncd.conf
