BSNL 3G in Chennai on a Samsung SGH-i780

I got myself a BSNL 3G sim in Chennai. This was a prepaid card for Rs 180/- and had Rs 20/- worth of talktime on it.
Getting it to work was an adventure worth blogging!
I have a Samsung SGH-i780 Windows Mobile Phone with 3G. When I called up the customer care of BSNL, the lady at the other end asked me what phone I had. When I gave her the model number, she said shes never heard of it and wouldnt know if my phone would work!
I then turned to my good ole friend Mr Google. Surprisingly, the community around this is very large. There were people running the 3G service on their iPhones (jailbroken), and other such phones.
I got the information I needed in a matter of minutes. The steps are:-
a) Change the band in the phone's settings to WCDMA. This can be found under "Settings" --> "Phone" --> "More" --> "Band Selection"
Once I did this, I got a warning that wcdma works only in 3G coverage areas!
The moment I did this, I got a large 3G icon on the top status bar of the phone.

b) The next step was to set up the data service. For this I navigated to
"Settings" --> "Connections" ---> "Connections" ---> "Manage Existing Connections" --> "My WAP Networks"
c) Create New Connection by clicking on New in the "Modems" tab.
d) Enter a Name for the connection: "BSNL 3G"
e) Select a Modem: Cellular Line (GPRS)
f) Click Next
g) Access Point Name: "gprssouth.cellone.in"
h) Click Next
i) Leave all the fields in this screen blank (User Name, Password, Domain)
j) Click on Finish.

Open up Pocket Internet Explorer and type in any url say www.google.com
You can see the 3G data connection getting setup. once this happened, I got a small 3G icon sitting atop my signal indicator icon.

Voila... Im connected on 3G!!!

I tried the speed test at speedtest.dslreports.com/m and it showed an amazing 1mbps!
Youtube plays without buffering.
Way to go BSNL; if only they got their act together. I cannot seem to find out where and how to recharge the SIM. The call center lady asks me to go to ezreharge.in but they dont have BSNL as an option!!
But I am so glad that 3G has finally come into the country and it works well too!

Howto connect to the Internet using ZTE AC 8710 USB EVDO modem and Reliance Netconnect Plus service in Ubuntu

-------------Update on 26 Dec 09 ----------------------------------
Ive upgraded to Ubuntu Karmic Koala (9.10) and found to my pleasant surprise that I dont have to do the modeswitch as explained below... The kernel parameters are required to be passed at boot time but once you insert the modem, the switch happens automatically! Upon insertion, my dmesg shows this:
1781.557336] usb 4-1: new full speed USB device using uhci_hcd and address 7
[ 1781.728425] usb 4-1: configuration #1 chosen from 1 choice

[ 1781.740855] usb 4-1: GSM modem (1-port) converter now attached to ttyUSB2
[ 1781.744782] usbserial_generic 4-1:1.3: GSM modem (1-port) converter detected
[ 1781.745112] usb 4-1: GSM modem (1-port) converter now attached to ttyUSB3

[ 1781.747527] usb 4-1: GSM modem (1-port) converter now attached to ttyUSB4

So I directly run wvdial cdma and connect.
Ps. I am still not able to use Network Manager which now includes an entry for Reliance in the Mobile Broadband section.

-----------------------------------------End of Update------------------------------------------------

The prerequisites to achieve the above are:

1. An activated Reliance Netconnect Plus EVDO service with the ZTE AC8710 EVDO modem.

2. A laptop/desktop with Ubuntu Jaunty Jackalope (9.04); It could/should work with other flavors/versions too with minor tweaks.

3. The usb_modeswitch utility from here --> http://www.draisberghof.de/usb_modeswitch/

4. The wvdial package.

The steps:

1. First download the usb_modeswitch utility and either compile it or use the binary (this worked in my case).

2. This utility is required to switch the ZTE modem from mass storage mode to modem mode. This is because ZTE cleverly added a usb storage mode which could allow them to bundle the windows driver and utility along with the dongle thus ensuring that people using netbooks etc (those without CD-Rom drives) could install and work with the modem. Unfortunately in Linux (Ubuntu Jaunty in my case), this does not happen and the device shows up as a mass storage device always thus leading to an impasse.

3. The next interesting point to note is that with Jaunty, the usbserial module has got built into the kernel instead of being a loadable module (This is the primary difference when working with earlier flavors like Intrepid- 8.10 where this module has to be loaded with the modprobe command).

4. Hence the parameters to the usbserial module have to be passed at boot time. One needs to add the following two values (usbserial.vendor and usbserial.product) to the end of the kernel line in the /boot/grub/menu.lst for the default kernel. In my case it looks like this after modification ( I am making the assumption that people know how to edit files in Linux):-

kernel /boot/vmlinuz-2.6.28-11-generic root=UUID=61f8e10e-6e9f-44c9-8e41-43deb8589139 ro quiet splash usbserial.vendor=0x19d2 usbserial.product=0xfff1

5. The next step is to unzip (optionally compile ) and install the usb_modeswitch tool. This puts a binary called usb_modeswitch in /usr/sbin/usb_modeswitch and the configuration file in /etc/usb_modeswitch.conf

6. Edit the /etc/usb_modeswitch.conf file to reflect the modem type and other settings. In my case the relevant line numbers (582 to 591) look so: -

   582 DefaultVendor=  0x19d2
583 DefaultProduct= 0xfff6
584
585 TargetVendor=   0x19d2
586 TargetProduct=  0xfff1
587
588 # only for reference
589 # MessageEndpoint=0x05
590
591 MessageContent="5553424312345678c00000008000069f030000000000000000000000000000"

7. The next step is to reboot after saving all changes to ensure that the usbserial module gets the required values.

8. After rebooting, we need to now switch mode. To do this, insert the USB modem, wait for it to get recognized as a mass storage device and then run the command (as root) usb_modeswitch. If one tails the messages file (tail -f /var/log/messages), one can see that new devices such as /dev/ttyUSB0 get created.

Before switch the log looks so: -

usb-storage: device scan complete

[ 2326.587996] scsi 6:0:0:0: CD-ROM ZTE USB Storage FFF1 2.31 PQ: 0 ANSI: 2

[ 2326.656896] sr0: scsi-1 drive

[ 2326.657023] sr 6:0:0:0: Attached scsi CD-ROM sr0

[ 2326.657121] sr 6:0:0:0: Attached scsi generic sg2 type 5

After switch it is:-

usb 2-2: new full speed USB device using uhci_hcd and address 10

[ 2328.646405] usb 2-2: configuration #1 chosen from 1 choice

[ 2328.649209] usbserial_generic 2-2:1.0: generic converter detected

[ 2328.649622] usb 2-2: generic converter now attached to ttyUSB0

[ 2328.652650] usbserial_generic 2-2:1.1: generic converter detected

[ 2328.653049] usb 2-2: generic converter now attached to ttyUSB1

[ 2328.655786] usbserial_generic 2-2:1.2: generic converter detected

[ 2328.656234] usb 2-2: generic converter now attached to ttyUSB2

[ 2328.658435] usbserial_generic 2-2:1.3: generic converter detected

[ 2328.658781] usb 2-2: generic converter now attached to ttyUSB3

[ 2328.661470] usbserial_generic 2-2:1.4: generic converter detected

[ 2328.661814] usb 2-2: generic converter now attached to ttyUSB4

9. Once this is done, we now need to run the wvdialconf tool to create the wvdial.conf file. In my case, it could detect the ZTE modem and detected a 9600 baud capable modem.

10. We can now edit the /etc/wvdial.conf file to add other values including the username and password (the reliance number associated with the EVDO service is both in this case). After it is done, my wvdial.conf looks so: -

     2 [Dialer cdma]
  3 Stupid Mode = 1
  4 Inherits = Modem0
  5 Password = 93xxxxxxxx
  6 Username = 93xxxxxxxx
  7 Phone = #777
  8
  9 [Modem0]
 10 Init1 = ATZ
 11 Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
 12 SetVolume = 0
 13 Modem = /dev/ttyUSB0
 14 Modem Type = Analog Modem
 15 ;Baud = 9600
 16 Baud = 115200
 17 FlowControl = Hardware (CRTSCTS)
 18 Dial Command = ATDT
 19 ISDN = 0

Pl note that I added the [Dialer cdma] part and also changed line 15 from 9600 to 115200 and it works just fine!

11. Once this is done, just run the command wvdial cdma and if all goes well, you should be connected. my final output, once connected looks so:

--> WvDial: Internet dialer version 1.60

--> Cannot get information for serial port.

--> Initializing modem.

--> Sending: ATZ

ATZ

OK

--> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0

--> Modem initialized.

--> Sending: ATDT#777

--> Waiting for carrier.

12. Thats it!! Fire up your browser, email client etc etc and happy surfing. I am getting 500 Kbps in Chennai and Hyderabad.

ps. i found out that i hadnt had pppd installed so had to install that as well.

I know that there might be a more elegant GUI way of doing this but this is the best I could do after reading a lot of stuff that other people had done.

Apple digs its own grave: The iPhone3G in India

I have been watching eagerly for the Apple iPhone3G in India. I was one of the millions who pre-booked on both Vodaphone and Airtel websites. I was disgusted to receive a mail on 20 Aug 08 from both Airtel and Vodaphone exhorting me to deposit Rs 5000 and Rs 10000 respectively to get my hands on the "iPhone that Ive been waiting for". The email also innocently mentioned that the iPhones are priced at Rs 31000 ($715) and Rs 36000 ($830) for the 8GB and 16GB models!!!
Now what kind of fools do they think we are? The questions that first occured to me were:-

Would I buy a phone that:

a) costs Rs 31000 and upwards

b) does not let you use Bluetooth for anything but headset

c) does not have any memory expansion slot

d) does not let you change the Battery

e) does not let you sync if you are on a Linux desktop?

f) Has 3G capability but wont be useful for about 2 years since there are no 3G networks in India.

g) Is network-locked to Airtel or Vodaphone

My response was a overwhelming NO to all of the above.

Why couldnt the so-called business brains at Vodaphone and Airtel use their brains for once? Every Marketing/Strategy person worth his salt knows that India is a volume-based market. Did Airtel not want to convert even .01% of their 60mn plus users?

Even more hilarious was the statement by a Vodaphone chappie who says that prices are expected to fall in the coming months!! Well Mr Vodaphone, who would then buy now?

Apple could have done well with retailing the phone through Reliance because, whatever said and done (mama-he-pinched-me style of corporate governance notwithstanding) , these guys have mastered the art of commoditising everything in India.

So I would never think of giving up my HTC-Touch/Nokia E71/Blackberry/Your-favorite-Phone for the iPhone unless it sells at 10-12k.

my experiments with meraki

I had heard a lot about Meraki and how they were trying to change the way people build and use mesh networks. I called up meraki sales to find out more. surprisingly, the person on the phone wasn't very forthcoming with any answers. when I asked him whether anyone from india had bought the nodes, he said that they'd sold quite a few in the country. and then when I asked him to give me some references so I could go talk to these people and also see the meraki nodes in action, he tells me that information is confidential! the whole attitude was a take it or leave it.
however, being inquisitive, I just went ahead and placed an order for 3 outdoor nodes (standard) for $99 apiece which cost me Rs 6500 after customs and frieght.
the meraki's came in their own green boxes with a PoE injector and 2dbi antenna. assembly was quick and painless and we could register them on the dashboard.
the best part about them was the zero configuration required and auto config in gateway or repeater mode. we were able to see the merakis on google maps from the dashboard.
we took some readings and found that the range with the default antenna is dismal. it barely covers 50m in standard environment and around 75 m in open ground.
the captive portal is not configurable beyond the text and there is no user authentication at all!
we are now planning on trying them out with larger gain antennae.
