Inserting the SIM card
Please ensure the SIM card is a 2G compatible Micro SIM card. The
SIM may also be 3G and 4G capable as well, as long as both the
SIM and the network also support 2G. Do not use a SIM card for a
tablet, as these only support data, and do not support voice and
SMS. You simply require a mobile phone type SIM card.
