Mobile telephony in emerging markets: The importance of dual-SIM phones

2020

Abstract A substantial share of customers in emerging markets use dual-SIM phones and subscribe to two mobile networks. A primary motive for so called multi-simming is to take advantage of cheap on-net services from both networks. In our modelling effort, we augment the seminal model of competing telephone networks á la Laffont, Rey and Tirole (1998b) by a segment of flexible price hunters that may choose to multi-sim. According to our findings, in equilibrium, the networks set a high off-net price in the linear tariffs to achieve segmentation. This induces the price hunters to multi-sim. We show that increased deployment of dual-SIM phones may induce a mixing equilibrium with high expected…

Mobile Telephony in Emerging Markets: The Importance of Multi-Simming Customers

Rapidly increasing sales of multi-SIM phones, mobile penetration rates above 100% and reported customer behavior all point to the fact that a signicant share of mobile customers in emerging markets tend to use more than one SIM card. A primary motive for this is to avoid making expensive o-net calls. We add a segment of exible prepaid customers, who choose to "multi-sim" in equilibrium, to the seminal model of competing telephone networks a la Laont,
