You might be wondering how many sim cards you need for your team. Here are a few examples that can help.

Listen-Listen

You will need one sim card per base and each rover/tablet combination. For example, if you have a BRx7 set up as your base station, and three other BRx7 measuring points with tablets, you will need four sim cards and plans.

The base station won't need a tablet once it's set up, but it will need a sim card. The three rover/tablet combo will each require a sim card either in the rover or in the tablet, but not both. A sim card in the BRx7 will use less internet and a one gigabyte plan is more than enough for that. If you use the sim card in a tablet that is cell-enabled, it can use more megabytes, but might be more convenient as you can use websites, emails or internet chat from the field.

Network Rover

If you are using NTRIP or some other service to get RTK corrections, you will need one sim card for each rover/tablet combination you have. In the example below, you would need three SIM cards.
