3 days ago, I did a change in /system/etc/ppp/peers/pppd-ril.options.
This is the orignal content of the file.
Just by commenting or remove line 18,
we may able to get better 3G network speed. The change may enable the Van Jacobson style TCP/IP header compression. Your cellular network may or may not support this feature. My 3G cellular network (Celcom Malaysia, HSDPA 3.6Mbps) seem to be supporting this feature.
Before the change, I got (down/up) 3.4/0.5 Mbps, but, after the change, the result is quite impressive as we can see in the screenshot. Sometime, I got about 2x of download speed when download podcasts MP3s, from 400 kBps to upto 800 kBps.
Mbps : Mega bit per second
kBps : kilo BYTE per second
Anyone who tried this hack/modeither for 3G or 4G, please report your before and after results.
Remember to reboot after changes
Thank you
