It seems you’re out of luck:
We’re not planning to support EU433 officially. With V3, this will be much easier to do for private networks. In EU, on the public network, we stick to 863-870 MHz.
For Israel, https://www.thethingsnetwork.org/docs/lorawan/frequencies-by-country.html#i shows no plan yet:
Country Frequency Plan Regulatory document … … … Israel EN 302 208
The latest LoRaWAN 1.1 Regional Parameters is the first to mention Israel:
Country name Band / channels Channel Plan … … … Israel 433.05 - 434.79 MHz EU433 915 - 917 MHz Other
However, for that, @htdvisser already wrote in October 2018:
TTN’s official recommendation is to wait until the LoRa Alliance publishes a regional parameters specification that is suitable for Israel’s 915-917 band. Until then you could experiment with the 433MHz band (but you will need different hardware for that).
I do know that the LoRa Alliance has been working on a “middle east” regional specification, but I can’t share any details about that yet.
I’m very sorry that I can’t be of more help, this is out of TTN’s control, so we’ll just have to be patient.
If, alternatively, you want to see if TTN wants to support EU443 after all, then see https://www.thethingsnetwork.org/forum/t/proposal-for-eu-433-frequency-plan/13090.
