The CloudRF free plan was discontinued in March 2021.
THERE IS NO FREE PLAN ANYMORE
It’s gone.
In it’s place there is a $5 sub-ghz plan which will let you do 10km radius and up to 1000MHz.
This costs $5 which means it’s not free anymore.
The free plan was retired in march 2021
Please note there is no free plan. It’s been removed.
