How to use two sim cards and memory card all at once

[chayanray]

Has any one tried with the external sim adapter to use 2 sim cards and memory card simultaneously?

I tried but it seems that internally it has been locked from software, if i use memory card the second sim card wont be detected.

If anybody has succeeded please respond.

Hi @chayanray,

Using two SIM cards and a memory card at the same time is not possible. The memory card tray allows you to use either a second SIM card or an additional memory card. Do not cut your SIM card, as this may damage your device.

Some time ago I looked through the kernel sources and found a kernel limitation. They keep the SIM2 servicing hardware switched off if an SD card is successfully initialized. I think it would be possible to overcome the limitation using a patched kernel or with a more comprehensive adapter that could temporarily hide the SD card from the kernel. I didn't try to build such an adapter yet.
