After insert SIM card, the signal will shows at the status bar.

  • If there is no data flow up and down arrows
    • Check whether Mobile data turns on. From Settings>Data usage>Mobile data.
    • Check whether the SIM card can be used.
    • Check APN Setting, From Settings>Cellular networks>Access Point Names, add or select an APN.
  • If there is data flow, but app has problem when connect its' server
    • Click Settings>About POS>POS Configuration>Merchant Self Test>Advance>PingTool, ping some well-known website, if success, the network is good, if fail, still need to check is there any settings not correct.
  • If there is data flow, but signal is weak, please use the same SIM card testing in Mobile phone or other terminals, at the same place, if good in other device, perhaps hardware error.
