I have a dm800hd with an old estar sim that i am having a lot of trouble updating and I would like to order a new SIM that will allow me to upgrade/update the image much easier.

My question is which SIM do I need to order and which is better. In the online shop I see 2 sims for the dm800hd:
DM8000HD NC3 Japhar and DM800HD NC3 SuperSim3

Your input is much appreciated.
Thank you
