dont waste your time searching for alternatives.
the hypercard is the only one working everywhere in any phone with 3g
you have to have the STK.apk in your phone (sim toolkit) and you can switch without pulling off anything or swithing off anything.
the cutting is really easy. i was frieghtend too. but it is easy. and you dont have to be precise. sone glitches here and there are not making the sim malfunction.
it switches networks within 10secs and grabs APN settings for new network after another 10 secs.
you have to login to your gmail afterwards once. thats it.
i am forwarding my calls from private to corporate sim. so i am always reachable via private.
I can confirm this. Tried several adapters before. Hypercard is the only one which works with two 3G SIM cards.
Using it right now with 2 Softbank SIM cards (private and business) in Japan.
Programmed forwarding calls for both numbers, so whatever SIM is active, I get all calls from both numbers.
Using MultiSIM as well to see which SIM is active. Good program, only it does not support the switching between the SIMs, so I have to go thru the SIM Toolkit.
As mentioned in an earlier thread, the only annoying thing is that I get a "wrong password" message for Google mail every time I switch SIMs. Anybody has a solution for this?
