Have you tried the latest version of Opera? It has settings for slow connections that reduce download sizes of pages and images. Also, it is the easiest browser to use with images disabled, easy toggle right there on the page.
You can also run Opera Mini on your desk top. This is the smart phone version of Opera. The pages look good, and there is only a fraction of MBs used compared to the regular browsers. If interested, a quick search will fix you up.
I had heard that about Opera. I’ll give it a try. Thanks!
