The Wall Street Journal has just confirmed that Apple has announced Japanese customers will be able to use micro SIM cards with carriers outside of the country. The announcement comes after rumors that iPad 3Gs in Japan may be carrier-locked.
This doesn’t mean that Japanese users will be able to take advantage of carriers outside of the country when in Japan, but rather be able to save money on roaming charges by utilizing a micro SIM when roaming internationally. If the rumors were true, that would have meant Japanese customers would have been forced to incur the high roaming charges charged by the only Japanese iPad carrier, Softbank. NTT DoCoMo had plans to offer the device but backed out after Softbank entered an exclusive deal with Apple.
