Last month, we reported the technical issues regarding iPhone 4S not supporting China Mobile SIM cards. This issue was confirmed by Apple as well as China Mobile. Now the good news is that the issue has been fixed. Apple has a really big heart because Appel fixed this issue without partnership.
Apple is yet to strike a deal with China Mobile over the iPhone 4S. However, now Apple has decided to support China Mobile customers who want to use its latest smartphone with the carrier unofficially.
China Mobile announced earlier this month that Apple modified the way in which the iPhone 4S interacted with China Mobile SIM cards to ensure that all devices purchased after 8 February 2012 would connect to the world’s largest carrier without any problems. China Mobile said that customers who purchased before 8 February 2012 will get an iOS update shortly after Apple’s iPad 3 event on Wednesday, 7 March 2012. The iOS update is expected to eliminate the issues for their smartphones as well.
The Next Web had a theory that the GSM chip could not support the E frequency band. According to this theory, users could not make calls despite a full signal. While this may be a hardware problem, it seems Apple has been able to rectify the issue by modifying its software. This sounds bizarre. Yet, it is true.
However, iPhone 4S still does not support the China Mobile’s TD-SCDMA 3G network. Thus, it is restricted to 2G data connections only. However, this does not seem to be a problem for more than 5 million subscribers who still choose to use iPhone 4S. Probably because using any iPhone in China is a status symbol today.
