Proposed solution
Kannel combined with MessageFormat seems like the best approach for our requirement as it seems to be the most versatile one. It should satisfy most of our implementers due to the sheer amount of supported interfaces and the possibility of costs being covered by the government agreements with SMS providers. It also has little to none requirements (though those might be outdated they are still coming from the official user guide) and is configurable with a single config file, which should make it easy to incorporate with our docker environment.
