0.2 Prepare SIM Card and working condition
1) For GSM/GPRS/EDGE/HSDPA/HSUPA/HSPA/HSPA+/4G LTE networks or TD-SCDMA networks,
please get a SIM card with data business.
2) For CDMA2000 EVDO/CDMA1x networks, please get a UIM card with data business or inform us
before order if the network uses non-ruim (nam-flashing).
3) Make sure the sim card or uim card is with enough data business and balance.
4) 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.
