Cellular data limitations include limited speeds, limits on unlimited plans, and limited coverage. While using cellular data may be a simple and cheap way to get internet connectivity off-grid, it may not be the most reliable option. Alternative solutions to consider include satellite internet, which is often the best option for remote locations, and can provide high-speed internet service. Another option is using a signal booster to amplify weak cellphone signals and improve connection consistency and speed. Additionally, turbo hubs or sticks can create a hotspot for multiple devices to connect to the internet, and ham radio can be used to connect to messaging systems and networks. It is important to consider the pros and cons of each method and choose the one that best suits individual needs.
