This bypass method & tutorial compared to PDANet, FoxFi, NetShare, EasyTether, Wi-Fi Tether Router, and sshuttle tunneling:
|
||||
|
||||
. Reliable with little to no speed reduction.
|
||||
|
||||
. Plug and play, works with other devices without installing apps.
|
||||
. Plug and play, other devices don't need to install apps to have internet.
|
||||
|
||||
. Safe from your telecom, but make sure to lie well if questioned for excessive data usage.
|
||||
|
||||
. Bypasses throttling such as limited video quality on YouTube, and censorship.
|
||||
. Bypasses service specific throttling such as limited video quality on YouTube or other streaming services, and censorship.
|
||||
** Other devices have to install an app for this goal, it's unavoidable.

This guide is tested from an unlocked US https://swappa.com/listings/google-pixel-4a-5g/unlocked[Pixel 4a 5G], it can be had for $100.

== Preparation
|

. https://topjohnwu.github.io/Magisk/[Install Magisk]; read "Getting Started", then "Patching Images".
|
||||
|
||||
. Install the following apps:

* A https://f-droid.org/repo/jackpal.androidterm_72.apk[terminal emulator]; for that app make sure to allow all permissions it asked for.

* https://apkpure.com/network-signal-guru/com.qtrun.QuickTest[Network Signal Guru] for its radio band locking to maintain and increase network speeds.

* https://github.com/AdAway/AdAway/releases[AdAway] to block Network Signal Guru's advertising.

||||
|
||||
* https://apkpure.com/netmonster/cz.mroczis.netmonster[NetMonster] for its network monitoring. Without it, you are practically blind to what bands are used, and what the various signal strengths are; this is very useful information.

=== Testing mangling support
|

. Open a terminal emulator.

. `$ su`

. `# iptables -t mangle -A POSTROUTING -o null -j TTL --ttl-inc 1; ip6tables -t mangle -A POSTROUTING -o null -j HL --hl-inc 1`

** No output is good/desired. If this is the case, link:#skip-ahead[skip ahead] to blocking Android snitching, and spoofing TTL & HL.

TIP: After enabling USB tethering, enable "Data Saver". This tells Android to restrict data to USB tethering and what app is at the forefront only.

|

For example, T-Mobile USA's agreement with AT&T allow the usage of AT&T towers, but only up to 250kbps download & upload speeds is allowed while roaming on AT&T's network.
