Then the trending issue of the day. Equitel. Safaricom had taken Equity to court and sounded a big warning on the use of thin sim. http://www.businessdailyafrica.com/Corporate-News/Safaricom-sounds-warning-t... London-based GSMA, the global association of telecoms operators using the GSM technology, wrote to the Kenyan authorities warning of the risks that use of the slim SIM cards pose to the integrity of the mobile telecommunications platforms.The GSMA said the overlay SIM (which is embedded between a normal SIM card and the device) has the potential of harvesting and revealing sensitive data passing the system. Of course we all know Safaricom failed miserably in stopping Equity from progressing with its plans. Now the thin sim is here, and Equitel has said it will encrypt all data to and from the thin sim. Can experts in this area assure us that the use of thin sims will not affect the integrity of M-Pesa transactions? Regards
