4. Preparations for
using the
smartphone
You must insert at least one SIM card and
charge the battery before you can use the
smartphone.
4.1.1. SIM card
Purchasing a SIM card involves choosing a
network provider, telephone network and
plan.
Therefore, check out which plan from which
network provider is best suited to your
telephone usage before purchasing the SIM
card.
You will also receive your telephone number
with the SIM card. SIM cards can also feature
additional memory functions (e.g. for the
phone book or SMS messages).
• Store all SIM cards out of the reach of
small children.
• Handle your SIM card carefully because
the card and its contact points can be
easily damaged through scratching or
bending.
