H720 Quick Start
Before Installation and Configuration
1. H720 router has different version. Study your router version before installation.
2. For GSM/GPRS/EDGE/HSDPA/HSUPA/HSPA/HSPA+/4G LTE version, please get a SIM card with data
business.
3. For CDMA2000 EVDO/CDMA1x version, please get a UIM card with data business or inform us before
order if the network uses non-ruim (nam-flashing).
4. Make sure the sim card or uim card is with enough data business and balance.
5. Make sure the signal is good enough where you test or install the router. Weak signal will make the router
no work. If you find your signal strength is not good, please contact us for high gain antenna.
6. Different countries and carriers use different network band and frequency. E-Lins packs units with free
world-wide-use antenna. It can work, but the data speed or signal may not be good at your sites. Please buy
dedicated high gain antenna from your local suppliers or contact E-Lins to OEM/ODM the antenna.

network only. For EVDO network or CDMA network, please refer to manual or contact us freely.

Switch Rules
On Time Check this, the two SIMs switch with trigger of time schedule.

goes via Master SIM, once Master SIM is failed, switch to backup SIM.
Once backup SIM is failed, the data traffic switches to Master SIM.
On Signal strength Set the signal ASU value from 1 to 30. For example, set value as 10,
the data traffic will switch from Master SIM to backup SIM if master SIM
signal value is less than 10.
On dial fail Master SIM and backup SIM switch with trigger of SIM dialing retries.
For example, set value as 5, the data traffic will switch from Master SIM
to backup SIM if master SIM dialing failure reaches 5.
On data limit Master SIM and backup SIM switch with trigger of SIM data limit.
