2.2 Wireless Carrier Requirements


The LevelSender system supports using dynamic IPs for the Home Station and the remote LevelSender stations.

LevelSender 5 operation requires setting up a cellular account with Solinst (discussed below), or a wireless carrier of your choice. Request a data usage service plan for a 4G LTE-M network. The LevelSender 5 uses a 4G LTE UE Category M1 device (700/800/850/900/1700/1800/1900/2100 MHz).

Solinst offers a SIM card that is set up based on your data needs. The Solinst SIM card scans multiple service providers and automatically connects to the strongest network in your area. Solinst offers low cost, data-only cellular plans that are managed and billed directly, monthly or annually by Solinst.


If setting up your LevelSender using Solinst Cloud, you will use a Solinst SIM and data plan.

You do not require voice access or voice features. If you plan on sending SMS reports, you will require text messaging, but ensure texting charges do not apply (i.e. unlimited texting).Your cellular service provider will give to you an activated SIM card, APN (Access Point Name), account type, user name, and password.


See our LevelSender Preparation Guide for more information on cellular service plan requirements.


You will also require an email account dedicated to sending and receiving email at the Home Station, as well as separate, unique email addresses for each LevelSender station, if not using the FTP option. A LevelSender email address is also required if you would like to allow remote updates. This can be set-up on your own, or with the help of your IT department.


2.2.1 Installing the SIM Card


Solinst SIM cards come pre-installed, if ordered with the LevelSender.


The LevelSender uses a standard/mini size SIM card (15 mm x 25 mm). A SIM card adaptor can be used, if required.

To install the SIM Card:

  1. With the top cap removed (see Section 2.1.2), insert the SIM card into the slot on the top of the LevelSender as shown in the photo, with the chip/metal contact towards the battery sleeve and beveled edge first.


    To remove the SIM card, press down on the card and it will spring up and out of the slot.

  2. Lower the top cap over the installed antenna (see Section 2.1.2). Push the top cap into place. This may take some force, as there is an o-ring on the top of the LevelSender.
  3. Replace the three screws to secure the top cap.
  4. Ensure the grommet is in the nut and install the nut over the antenna and thread onto the top cap.
