3.3.1 SIM/UIM Card

Insert the SIM/UIM card.

TW810 supports normal SIM/UIM only, so if you’re using a Micro SIM or Nano SIM card,
you may need to use a Micro SIM or Nano SIM to Normal SIM card adapter.
Make sure your NB-IoT Modem is powered off, then use a needle object(such as a pen) to
push the button near the SIM/UIM card holder, it will flick out immediately. Put the
SIM/UIM card to card holder with chipset upside, insert it to NB-IoT Modem and make
sure it’s tightly matched.

Warning: Never install SIM/UIM card when NB-IoT Modem is powered on.

4.3.11 Reconnect

In real application, the data center may be shut down or have issue, and that will cause
TW810 disconnects from data center, while in order to keep TW810 always online, it will
try to reconnect the data center, and that will cause unnecessary data flow. So you can
configure those 2 functions to save the data flow, when Reconnect Time Interval enabled,
TW810 will try to reconnect data center, and if Connect Retry Times exceed the value you
set, while TW810 is still unable to reconnect to data center, TW810 will do exception
handling.

4.3.12 ECHO Heartbeat Interval

We suggest you keep it as default settings, as it is not supported by TW810 now.

4.3.13 TTL Heartbeat

It’s a reserved feature, we suggest you keep it as default settings, as it is not supported by
TW810 now.
