Do you know any service that does that? Right now I have reached 5GB of my phone contract and I have to navigate with a very low speed. I was thinking to write a simple service that takes the URL as request and sends back the page but in read mode or in a very minimal way keeping focus only on the content. But I want to check if a service like this already exists.
EDIT: I just realized I’m in programming, whoops! This is more of general tech advice, because I’m guessing you’re looking for an actual service that you can integrate with.
This reminds me of Opera Mini way back then in the Symbian / Windows Mobile era before the iPhone. It worked by basically rendering sites on Opera’s servers and heavily compressing the content before it reaches your phone, making it far easier to navigate and with minimal data use.
Opera Mini still exists today, but I’m not sure about the data usage since sites nowadays are more dynamic and I’m sure they had to adjust their process to adapt to that.
If you’re considering it, please note that you’re effectively trusting your browser sessions with Opera, since it’s a proxy browser. Use it as if you’re incognito, and don’t login.
