 The following purchases are recommended:
 1. 1 x [Onion Omega 2 LTE](https://www.mouser.com/ProductDetail/Onion/OM-O2LTE-NA?qs=yqaQSyyJnNhhcT0W%2FqC0PA%3D%3D). The link provided is for the North America version. If you are not based in North America, please purchase the version for your region.
-2. 1 x SIM card. You will need to order this based on your cellular provider. Keep in mind that the Onion has *extremely high* data usage since it offloads its 720p30fps (~3 Mbps bitrate) encoded stream entirely over LTE. You will almost certainly need a custom data plan for this SIM. If data rates are a concern, consider using the Galaxy Watch/Java API which transmits at a much lower bitrate.
+2. 1 x SIM card. It is *highly recommended* that you purchase a static IP SIM card to work with the Onion although it is not mandatory.

Any lightweight, small ultra-wideband 4G PCB antenna should work. *See below note*
 4. 1 x [LiPo](https://www.adafruit.com/product/1578). Any lightweight, small LiPo should work. This battery will give the Onion enough battery life to last at least 20 minutes (the maximum flight time of the drone). *See below note*.
