3G Internet on Raspberry Pi - Success!

This is a bit of a brain dump of how I got a 3G USB dongle working on the Raspberry Pi. Following on from getting the Raspberry Pi to send SMS.

That's The Power Of Love

The first thing to say is use a powered USB hub! I had lots of problems getting the modem working when it was plugged directly into the Pi. A 3G signal takes more power than the Pi's USB sockets can supply.

3G Raspberry Pi

In the above image, you can see that the Raspbery Pi is plugged into the mains - via a 1.8A plug.
The USB cable has two male ends. The black plug goes directly into the Pi for data. The red plug goes into the mains via a 1A plug (an Amazon Kindle adapter).

I used a USB Y Cable to supply power and data.

I also tried plugging both plugs into the Pi - that didn't work either. You need a separate powered hub.

Rather than use two plugs, I'm going to try to find a mains plug with two USB sockets. Each socket needs to supply at least 1A. Something like this looks like it should do the trick.

Or, you can use a cable like this.

Put one male USB plug into the PI and the other into a power supply. The dongle fits into the female USB socket.

P-p-p-p-pick Up A PPPD

In order to get our network connected, we need to install the ppp package.

If You Think I'm Sakis, And You Want My Body...

I tried using wvdial and numerous other ways to connect to 3G. None of them worked reliably. In the end, I turned to sakis - the All-In-One script for connecting 3G modem.

Sakis says it is:

"The easiest way to have your 3G/UMTS/GRPS connection up and running."

I can't argue with that!

Installation is very simple:

First, download the latest version. The Raspberry Pi runs on an ARM processor, so this is the version we download.

The script is compressed. Unzip it.

Finally, we want to make the file executable so that we can run it.

Running sakis is quite straightforward. It has a basic GUI which will work even if you're just using the command line.

sakis3g interface

Sakis has a fairly comprehensive list of connection details - it should find yours automatically and present you with this screen.
sakis3g interface APN

If it doesn't know your connection settings (if you're on GiffGaff for example) you can manually enter them.

All being well, after a few seconds, you should see this screen.
sakis3g interface connected

You can now exit sakis. You will stay connected.

To check the details of your connection, run the following command:

You'll get back something like this:

That's it! You can now access the Internet via your 3G modem.

Surfin' Safari

One last tip for you! There's no need to start your window manager to surf the web. There's a brilliant lo-fi web browser called Lynx.

You install it by typing:

You run it by typing:

(or whatever website you want to visit).
lynx on the Raspberry Pi

So, that should be everything you need to get the Raspberry Pi connected over a USB 3G dongle. Have fun!

Magnificent! Thank you for this tip.
Ever since I ordered my Raspi, Ive been tossing and turning my brain on how I can connect to 3G with it.

Hi there,

I've been reading a lot about Raspi, being a former A-Level computer science student (back in the early/mid 1990s). It's a great idea. But after hearing more on the Guardian tech weekly podcast I got wondering, would is be possible to also create programming simulators for iphone/ipad/android as another simple way to get kids back into the fun of programming? Using some simple gamification to create interest.

Hello,

I've successfully installed sakis and get it worked perfectly. I've also installed no-ip client to get a dynamic IP and it works. I easily connect through lan via ssh and tightvnc but i cannot get access to ssh ot vnc via the 3G connection even if i use the direct IP read from ip addr
I've tried also without the lan connection, no-ip resolve the dns as I see it changes after a while, but no connection at all.. any suggestion?

Are you trying to SSH *in* to your Pi via 3G?

It's likely that your network provider is blocking the ports needed. Try moving your SSH daemon to port 80, or 8080.

Reply

changed to port 80. it's a vodafone sim that works perfectly with the samsung galaxy tab. no access, only via lan. network connection timeout.. i've also tried to change route priority to ppp0, no success.. as the no-ip client sends correctly the ip to their dns servers, the 3G internet connection works.. anyway i've tried to connect directly to the ip shown with ip addr (which is the same that appears after a while issueing a ping to the dns)
really strange....

this is the ip addr output regarding the ppp0 interface..

ok. I've fixed it. the main issue is that if you connect through a 3G USB dongle you don't have a public IP address but a network one. so you need a reverse connection. to do that, just act that way:
suppose you are trying to connect via a windows machine with a fixed ip and with a port forwarding in the router for port 22, with user USER and password psw
on raspberry machine, execute this command after the 3G connection:
ssh -R yyyy:localhost:22 [email protected]

where yyyy is a free port, xxx.xxx.xxx.xxx the fixed ip of the windows machine. once connected, authenticate with the windows USER psw. use sshpass -R yyyy:localhost:22 -p 'psw' [email protected]
install sshpass with apt-get install sshpass
replace psw with the windows USER password

you can use a ssh server (a free one such bitvise ssh server) running on the windows machine to get the connection.

on the windows machine, using a ssh client issue the command
ssh localhost -p yyyy where yyyy is the same port of the raspberry connection. you will get reverse access to the raspberry pi machine connected to the internet through a 3G USB dongle..

that's all. works perfectly.

Hi Terence!

First of all, thank you for posting these instructions.
They helped me setting up the GPRS connection from my raspberry pi tremendously! :)

One question though...
You mentioned at the beginning of your post that a powered USB hub has to be used.
I plugged the Huawei Vodafone modem directly into the USB slot of the RPi (without the powered USB hub) and it works fine. It successfully connects to the internet and I'm able to do all the browsing and stuff.

Since I'm using the latest revision of the RPi (rev 2, the one made in the U.K., bought in september 2012), have you perhaps heard if the USB powering problem has been fixed for that revision? Or is it possible that I'll will be experiencing the random dropping of my GPRS connection?

Powered hub is definitely a preferred solution, Y cable is not - "except" if you plug the red USB connector into another device, to get some extra power. I my case I've tried to plug it in TV (0,5A) and it worked. I have also plugged RPi into TV (1A) and it still worked.

Thanks for sharing this. I am interested in doing this with a prepaid SIM card that charges per txt and MB of data. As such, I want to eliminate unwanted background network access-- e.g. even when I am not using my Macbook, there are a lot of small internet accesses that I can snoop using netstat. Is this a problem with the Raspberry Pi? I want to leave the RPi on 24/7 and only plan on sending ~5 SMS messages per month at 10 cents each and am worried that the low level data usage will overwhelm the savings from $10 per 3 mo plan.

Could you possibly run netstat to snoop your internet connection for a while and give me an idea of how much background activity there is?

Reply
A picture of Terence Eden Terence Eden

With the default install, I think the only internet access should be from the update checker - which you can disable. If you only care about SMS, you don't need to use data at all.

Hey. First off, nice post. By far the clearest I've found on the subject. Not having much joy getting 3g going on my pi though. I get 'failed to connect' everytime. I'll list my process-
Using Huawei E3231 on 3 (UK)
Latest wheezy raspbian (fresh install and updated)
Dongle works as expected under windows
lsusb = ID12d1:1f01 (is that the issue?)
Followed your instructions
Get same error everytime

I'm still pretty new to all this so I'm finding it hard to even search for a solution. I'm trying to get my head around usb_modeswitch.
Unfortunately, I've not come across any reports of this device working with R-Pi. There must be a solution though(fingers crossed). Any ideas? Cheers

Hi again. I tried the recommended post. Didn't get far though. Couldn't get the thing to perform a switch. It states you use the command- /usr/bin/sg_raw /dev/sr0 11 06 20 00 00 00 00 00 01 00 to switch with sg3_utils. I get- do_scsi_pt: Bad address.
I don't know what the numbers represent in this command but I'm assuming it's that. I've posted a message on the other post(waiting for reply) but I thought I'd try my luck here as well. Cheers

I'm curious to know what speeds people are getting? I ran a quick speed test which showed 1MBps but that could be down to network congestion/weak signal.

I'm using a later Pi and mine works without a powered hub. The second USB slot is used for the keyboard/mouse via a PS/2-USB adaptor.

Hi Terence,

What are your thoughts with tethering an android phone via usb and using it as a modem for the pi?? Will the same steps you described above apply??? I have a Motorola phone running gingerbread and I want to send trigger commands to the pi. I have a few specific questions and I'm not sure where to start. Any help would be greatly appreciated.

Hi Mark,

There are two things you need to know first.
1) Does your phone support tethering via USB? (There should be an option in the settings menu)
2) Does your carrier allow tethering? (Some don't, or will charge you extra for it)

If the answer to both questions is "Yes" then it should work just fine.

There are a couple of good looking tutorials at

My project would be: to open my garage by a simple phone call, using a pi and a usb modem.
Do you perhaps know what I need to doe here? Receiving calls and checking IDs is simply done by AT commands? How can I tell if a call is about to happen, I mean how to recognize if a ring the modem? Do I have to poll something constantly, or is there a trigger somewhere when the modem rings?

Thanks a lot in advance!

First of all, you will need to find a USB dongle which will accept voice calls - many won't. You'll also need a SIM which your network provider has enabled for voice.

Well, it's over a year later, but, just for the fun of it: it's pretty straightforward to turn a Pi into a GSM gateway, capable of receiving calls (as an inbound route into Asterisk) and handling text messages.

I installed RasPBX (a Debian based Asterisk / FreePBX distribution), and configured the chan_dongle package.

Hello, I've eventually received a Raspberry Pi. I've successfully installed SAKIS3G and got access to Internet using a Huawei E1692 Internet Key. External USB hub is not necessary for the Internet key to work, but if any USB dongle is inserted in the PI when already powered, the Pi restarts. Any USB device has to be attached before powering the PI. Everything is OK if an external USB hub is used to provide additional power.

I use a Huawei E303 in a Raspberry Pi Model B (not sure if its the newer or older revision, but I bought it in September 2013). First I struggled quite a bit, since it worked reliably when hotplugged but not at boot-time. Then I found the post in this thread http://www.raspberrypi.org/phpBB3/viewtopic.php?t=32307&p=439933 about creating /etc/udev/rules.d/41-usb_modeswitch.rules which fixed the problem.

Now, everything is fine at boot-time and/or when hotplugged, but when I leave the Pi running then after anything between a few hours and 3 or 4 days, the interface just seems to vanish.

I thought it might be to do with power so, as suggested, I plugged the dongle into a powered USB hub, rather than the Pi directly. But it's still not solving the issue. Do you have any pointers for me on that? Any help would be much appreciated!

First, thanks for the post and to all who have contributed since!

Adding... I had numerous problems getting sakis3g just right on my Pi, from crickets at sakis3g.org to compliation problems. This post (http://insembedded.wordpress.com/2014/03/27/setup-3g-on-raspberry-pi-using-sakis3g/) fixed all that.

But then I kept getting connection failures from within sakis3g. So, I scrolled back to the top and started over with a powered USB hub, rather than directly connecting my dongle to the Pi. That worked! Never underestimate the power of power. :)

But... introducing the hub sort of shot my mobile project in the foot. I was trying to use a relatively old AT&T USBConnect Quicksilver device that works great on my laptop. But I suspect that it something of a glutton. So, I'm wondering if anyone has found a "low-power" 3G/4G dongle that works off of Pi power?

hi sufi,

is your usb modem installed properly?
i suppouse that it is found in 'lsusb'.
ssh to your rasberry.
type
ls /dev/ttyUSB*
is there anything (like ttyUSB0 or ttyUSB1 or so)?
if it is not,
did you modprobe it?
for your dongle command should be
modprobe usbserial vendor=0x0af0 product=0x5000
if you have not installed modprobe, just 'apt-get install' it.
if it is all ok and ttyUSB is located in /dev,
is dongle properly set in
nano /etc/asterisk/dongle.conf
near the bottom of dongle.conf find paragraph [dongle0]
uncomment and set path for audio and data (audio=/dev/ttyUSB0 say..).
if you are not sure for ttyUSB device, leave audio and data commented and uncomment and enter
imei and/or imsi numbers.
at least imei you will find printed somewhere on your dongle.
after restart all, log in to asterisk cli
asterisk -rvvvv
from cli type
dongle show devices
your dongle should be listed.
if it is not, check again all settings.
maybe your dongle is locked... google 'unlock 3g dongle'.
if dongle is listed, 'exit' from cli and check settings in raspbx gui.

Has anyone tried to boost the USB current in the pi and succeeded in plugging a 3g usb dongle directly (cf: http://www.modmypi.com/blog/boost-usb-current)?

Any suggestions welcome!
