Favrit highly recommends buying iPads with cellular connectivity (4G/5G)*. This way you are always online, even if your Wi-Fi fails, if you want to expand your seating area quickly, if you want to use it at a festival or other event and more.

If you buy an iPad with Wi-Fi, and your Wi-Fi system fails, you would have to share internet from a cell phone, which can be unstable and expensive, both with the data usage and lost revenue.
