looked like xox is better then xoxone.. more flexible in internet pass

Just check with you all the XOX dealer, currently what type of SIM card for the XOX?
I'm currently using the old Xinxun SIM card, planning want to change the new SIM card due to future devices will only support micro or nano SIM card.

Currently, is it mostly XOX simcard all in one with normal SIM with micro and nano SIM card ready? If do so, this will very very convenience to us to swap any devices between nano SIM to micro SIM or normal SIM card in case the new device has some problem. I don't like use manual cutting SIM card as it sometimes will cause unable put back to micro SIM from nano SIM card.

Anyway, you can also screenshot the current XOX simcard for our information.

Yes, we can use the 3rd party micro sim adapter.
But sometimes I experience help my friend put the nano sim with micro sim adapter, it is quite difficulty put the sim card (with micro sim adapter) into the SIM slot tray. Keep drop off the sim card during the SIM card in the SIM slot tray insert to the devices. 

Any recommend micro SIM adapter? Some 3rd sim adapter really lousy.
