Hello,

I recently purchased an android 5.1.1 unit for my car, and it has a USB cable which has a note where is written "3G" on it. I tryed to put my 3G dongle (ZTE) in it and after I rooted with KINGO ROOT and installed PPP Widget 3, I can't connect to the internet. Can someone help me please?
After I insert the 3G dongle into that cable, the PPP Widget asks for permissions for superuser and after that it says "Disconnected", and if I click "Configure" and "Edit current SIM profile", all are grayed out and I cannot change anything, because I have to put APN and dial number. If I click Connect, it stops at "Building network" and it freezes.
I also tried PPP Widget and PPP Widget 2, on the first it says something like "No drivers" and on the second it is the same like the latest. Can someone help me, please?
I mention the fact that I tried inserting the 3G dongle before rooting the device and installing the app, and it doesn't do anything. No preinstalled app to connect a 3G dongle.

Please post both "USB Log" and "PPP Log".
See "Troubleshooting" on the FAQs page about how to create them.

Thank you for you answer.
Until I'll arrive home to get the logs, the 3G dongle is ZTE MF710m, if it is an important information. I searched on google and I didn't found anything related to connecting this 3G dongle to an android device.

So, this is my story for this evening. I installed "SuperSU" (unistalled "Superuser" which came with root). Gave acces to PPP Widget, enabled logs from settings. The "Edit current SIM profile" is still grayed out (disabled) and when I enter it, all inputs are disabled.
I tried to hit "Connect" and it connected (without any credentials, APN or dialing number), but just one time, I tried after several minutes and it is stopping at "Building Network". When was connected, it appeared a key symbol in the device top status bar. I cannot connect no more since first time.
Another mention is the fact that when I enter the 3G dongle, in the top status bar it is a notification: "Storage safe to remove - You can safely remove storage.".

Here are the logs:

1. When the device succeded to connect, but without any APN or dial number, with the "key" icon on status bar of the device:

Ah, I half expected the outcome of the logs you posted.

You have a sort of modem that acts as a router. Your Android device does not connect to the Internet directly; it rather connects to the modem which then manages the real network connect/disconnect. You control it with a browser, it has a built-in minimal web server.
Now, if you "connect" PPP Widget it just means that the route to the modem is open. It does not mean that the Internet connection is up yet. Usually this is done with a button on the modem page.

With modems like this, there isn't anything which can be edited. I just noticed that there is a paragraph missing about all this in the FAQ page ...

There is a config option in the sense of "Open browser automatically if you have this modem". If it is enabled, the default web browser should open with the address of the modem after "connecting" PPP Widget. If that does not work for you, try to open the browser manually and send it to the address of your modem:

http://192.168.0.1

Unfortunately, it doesn't work... :( I also tried several URLs, ending with http://192.168.0.1 / 0.2 / 1.0 / 1.1 / 1.2...
You can see the error in the attached pictures..
The only solution is getting a new dongle maybe? Or it may exist other methods to connect mine?
Another mention is the fact that when I go in network settings, and I click VPN, it asks for a password (something with CREDENTIAL STORAGE password).

MF710M is not a hotspot/router so the http server inside probably doesn't have code for rendering its pages in your http client. Generally a hotspot is made to be configured over wifi in a browser while devices like MF710M are made to be configured from the Connection Manager that the mfgr provides.

You can try this url to see if you can get any info out of it with a plain browser:

http://192.168.0.1/goform/goform_get_cm ... re_version

but I think it will fail and that you'll need to wget or curl it from the http server.

I think the error message rather points to a route issue.

The "ip" tool can show the network details while the connection by PPP Widget is up. You need a terminal program for that though (like "Android Terminal Emulator").

$ su
# ip addr
# ip route

Thank you for your answers. I lost my pacience and bought a new 3G Dongle (Huawei E3131) and it works like a charm. It doesn't even require the PPP Widget, it is plug and play (for my device at least, I don't know for others). I just plug it and on the status bar appears the signal with a 3G icon. Maybe my device has some support software for this, because I have a dedicated USB cable for 3G.
My ZTE MF710m is lucky that it is unbroken, because I wanted so much to brake it into pieces.

P.S. Thank you for your efforts with PPP Widget, you really make happy a lot of people.
