The global outbreak of COVID-19 in 2020 has pushed EM to the top topic . As mobile phones have become ubiquitous, many scholars have shown interest in using mobile phone data for EM . This paper presents a systematic literature review about the use of mobile phone data for EM that includes 65 related articles written between 2014 and 2019 from six electronic databases . Five themes in using mobile phone data for EM emerged from the reviewed articles, and a systematic framework is proposed to illustrate the current state of the research . This paper also discusses EM under COVID-19 pandemic and five future implications of the proposed framework to guide future work.
