What RSim would unlock KDDI Japanese carrier? - GSM-Forum

Hey guys,

For the past two years, since iOS 7.0.2 until today iOS 8.2 the Rsim Mini I purchased two years ago has been working perfectly with my iphone 5s which is locked to KDDI Japan. Anyway yesterday the phone took me to the activation screen and even though I inserted a bunch of other SIM cards along with the RSim Mini it kept taking me to the activation screen. I believe that my Rsim Mini is broken and I need a new one. It doesn't lock the carrier anymore and the phone takes me to the activation screen. I restored and removed/inserted the SIM card many times but I believe the card is broken now...

Is there and new RSIM card that will let me use my KDDI iPhone 5s with T-Mobile in the States? Any chance I can get more than just 3G? Like 4G or LTE?

Please let me know and provide me with links I can purchase the cards.

Thank you, Jimmy

I was reading about RSim 10 and I was wondering if it can unlock my KDDI Japanese carrier. Do you think I should buy it?
