Which is around the same speed as TCP/IP tunneled over NRF23L01 radios. You shouldn’t expect massively fast speeds, as 300kbps was pretty typical during testing, which according to Wikipedia, is about what dial-up got with V.44 compression. Packets are split to prevent you from sending too many messages, as in their testing, ’s accounts were banned quickly. Then, you set up traffic to be redirected through that port with curl or Firefox. It connects to the WhatsApp API through a WebSocket and then acts as a proxy. The real trick for turning the WhatsApp messages into an internet connection the client can use is exposing a port from a local nodeJS web server. Then when in a restricted access setting, the client connects with a WebSocket and sends messages. A server is on one account and acts as a proxy to the broader internet and listens to messages to the server account. So, ahead of time, two accounts are set up.
In ’s case, cell carriers are pretty stingy with internet data when traveling in South America but often give unlimited WhatsApp data.
Funny enough, has a project that does exactly that by tunneling traffic over Whatsapp. In the air, we wondered how hard it would be to tunnel an internet connection over messaging. While the messages are handy for complaining about the seat size, it isn’t quite as exciting as access to the internet. As we returned from Supercon 2022, we noticed many airlines offer free in-flight messaging.
