AT#SINGLEAPNSWITCH=<mode>
If it is enabled and an APN network identifier or APN-related parameter is
updated, Modem can re-activate PDN context with changed APN if there
are no application working on the activated PDN context and APN name is
changed. If the PDN context is for LTE attach, UE will attempt to reattach
with changed APN. In other systems, this command works as if it is
disabled.
If it is disabled, the changed APN will go into effect at the moment when
the PDN context is deactivated and then re-activated. Power recycling is
one of operations that will have new APN activated.
