I added a new point to the main article relevant to the “skip the landline” model:
Innovations developed in high-income countries may have more impact in low-income countries. For example, renewable energy (wind, solar, hydro, etc) was developed in high income countries. But because of energy scarcity, investment in renewable energy has actually been higher in low and middle income countries than in high-income countries, since 2015. (see the Wikipedia article on renewable energy in developing countries)
