    You can read how to connect to the receiver's hotspot using the Emlid Flow app in the Connecting to Reach guide.

  2. In Settings, go to the Mobile data section.


    If the SIM card requires a PIN code, type it into the pop-up field on the Mobile data screen.

  3. Configure APN settings.


    This step is optional. If you don’t know your APN settings, contact the network carrier.

    Tap APN settings and enter your APN.

    Some SIM cards may require filling in all the fields in the dropdown menu.

    Tap Apply.

  4. Switch Mobile data on.


    Some SIM cards require enabling the Data roaming option to connect to the network.


    If you can't connect to a cellular network, do the following:

    • Make sure you're in an area with cellular network coverage.

    • Check the APN settings.

    If you still can’t connect to a cellular network, contact your carrier.

If everything is correct, you will see network bars and connection type next to the battery icon. Once Reach connects to the Internet, you can set it up to get corrections from NTRIP service.
