The Indonesian government blocked nearly 101 million prepaid SIM cards in March after mobile users failed to re-register their prepaid numbers with a valid identity document.
Meanwhile, 305 million SIM cards were re-registered during the period.
Market leader Telkomsel had 43.3 million blocked SIMs, while 3 Indonesia was second with 26.7 million.
In late October 2017, The Ministry of Communication and Informatics (known locally as Kominfo) ordered all mobile subscribers to re-register their SIM cards in an effort to clean up operators’ databases and combat misuse of SIM cards.
