Good Day Stefan,
Unfortunately, we no longer offer Rain fixed wireless package for new signups anymore,
If you have cancelled your Rain package, unfortunately, you will not be able to reactivate it.
However, you will can signup for a Cell C fixed wireless sim only package (as you already have the LTE router) provided you have coverage in your area.
To check if you have coverage, please follow the link below:
