Inserting the micro SIM card & the microSD card
Before inserting/removing the SIM card and the
microSD card, you should ensure the tablet is off to
protect it from corruption or damage. In addition,
regularly removing or inserting the SD card may cause
the tablet to restart.
Your tablet only supports micro-SIM cards. Do not attempt to
insert other SIM types like mini and nano cards, otherwise you
may damage your tablet.
