Leapfrogging was first used to talk about economic growth and industrialization. More recently, it has been used to talk about sustainable development in developing countries
In the case of M4D, the rapid mass adoption of mobile technologies can be explained by the "mobile leapfrog effect."
Mobile hacking: 24 Mobile hacks have also become a common way for people in developing countries to use mobile technologies. : 24 32 By sending credits to another person's mobile device, cash can be exchanged when it is needed.
Social impacts It also gives people the chance to form social, economic, and political communities no matter where they live. It also gives people a tool they can use to fight against human rights abuses from the ground up. This is to help create and support mobile citizens in developing countries.
Africa Mobile technology has made it possible for HIV/AIDS patients to get care, medical advice, and counselling at home. Cell-"Aftercare" Life's programme uses mobile phones to record and report a patient's medical status and drug dosage adherence.
M4D in medicine
 Their campaigns, "HealthSmart" and "Just-Tested," are meant to encourage safer sexual practises and give information about HIV. 
Programs with links
Here is a list of groups that work on M4D strategies and programmes:
GSMA Mobile for Development
The ICT Task Force of the UN
Support for the rights of African women (SOAWR)
There are criticisms and problems
Sharing and exchanging information and technical advances can make this easier and less expensive. However, many of the organisations that create and run M4D projects work in "innovation silos" that keep information separate. This keeps information separate threatens to create and solidify boundaries.
In the case of mobile adoption, both economic and knowledge-based differences in wealth are taken into account. So, they get more and more benefits sooner, which makes the knowledge gaps in society worse instead of better.
