At the bottom of configuration it is possible set rules for switching between two SIM
cards, eventually between two APN on one SIM card. Parameter Default SIM card sets default
SIM card from which will try the PPP connection. If this parameter is set to none the UMTS
router UR5 is launch in offline mode and it is need establish PPP connection by SMS
message. If PPP connection fail the parameter Switch to other SIM card when connection fails
ensure switch to secondary SIM card, if it is included and set, or to secondary APN of the first
SIM card. In case that the roaming is detect the parameter Switch to secondary SIM card
when roaming is detected enable switching to secondary SIM card, or to secondary APN of
the default SIM card. Parameter Switch to primary SIM card after timeout defines conditions,
how to switch back to the default SIM card.
Parameter Initial Timeout set time after which UR5 try to make connection with default
SIM card, range of this parameter is 1 up to 10000 minutes. Parameter Subsequent Timeout
set time period for every other next attempt to make connection with default SIM card, range is
1 up to 10000 minutes. Parameter Additive Constant set amount of time which is added to

attempt is extended about 30 minutes etc.). Range is 1 up to 1000 minutes.
The changes in settings will apply after pressing the Apply button.
Attention! Check PPP connection we recommended in case of uninterrupted running.
Note:
• MTU (Maximum Transmission Unit) – it identifies the maximal size of packet that
it is possible to transfer in the given environment.
• MRU (Maximum Receiving Unit) – it identifies the maximal size of packet that it is
possible to receive in the given environment.
Default value is 1500 bytes.
Other settings may cause incorrect transmission of data.
