Telemedicine works in developing countries because it is easier for a specialist to consult remotely when there are so few of them and being in all locations is not feasible.

For primary care, it helps in preventive care more than cure. Earlier detection of issues can make handling them a lot easier.

You need telemedicine precisely because there are few doctors to go around, and care can be expensive.

There are already few well funded startups offering this along with medicine delivery in India for example, who are doing well. 4G and mobile penetration makes it possible, it doesn't cover everyone but it makes a difference to a large chunk of the population.
