Internet Access via Cell Phone HOWTO

Nate Carlson writes "I've been searching for a decently fast, inexpensive wireless 'net access solution. It's finally here! Sprint recently cut their PCS Vision pricing so that US$40/mo gets you unlimited data and 300 voice minutes to boot. I've written up a document on how to get this working with Linux - it works great, and averages 7-12kbytes/sec download speed. All I can say is, wow!"

Symetric?

[skrowl]

Is it 7-12K upload speed as well

Re:Symetric?

Unlimited PCS Vision. Sprint may deny or terminate service without notice where use is in connection with server devices or host computer applications, other systems that drive continuous heavy traffic or data sessions, or as substitutes for private lines or frame relay connections. Unlimited PCS Vision offer for PCS Free & Clear Plans with Vision is: (a) only available with a Vision capable PCS Phone or PCS smart phone device; and (b) not available with Connection Cards, Aircards, or any other device used in connection with a computer or PDA - including phones, smart phones or other devices used with connection kits or similar phone-to-computer/PDA accessories. Sprint reserves the right to deny or to terminate service without notice for misuse.

They will just cut you off if you are running a server or some other mode that continuously uses up their bandwidth.

In the article they mention 7-12 kBYTES(56-96kbits about what 3G claims to be) which would be faster then 56kbits or 28.8kbits. The diffrence between bits and bytes is a factor of 8. It amazes me that no one ever seems to know the diffrence between kbit transfer and kbyte transfer. Either that or they allways get it wrong.

Great..except it violates the new TOS.

[Anonymous Coward]

Connection to the Vision network via anything other than a Vision enabled phone is a violation of the new TOS. In fact, SPCS has gone so far as to remove the PC connection kits from stores and the online shop.

Check out alt.cellular.sprintpcs for details.

No it doesn't.

Sprint to a crawl...

[jaredcoleman]

This sounds like a great idea for city-folk, but for country folk like myself, I think we're out of luck. Sprints PCS towers are great, but they are concentrated around urban areas. I can use my Sprint phone at work, but at around the same place every day on my commute home, I begin to lose signal. Many of my friends have that problem as well.

Has anyone else seen this in there area?

Get 1XRTT service from Verizion, 144Kpbs

[malakai]

You can get unlimited data access from them for 90 bucks a month.

60 bucks for the USB cable. Phone appears as a USB modem to the OS.

Re:Get 1XRTT service from Verizion, 144Kpbs

[novitk]

I just had this service(Express Network) cancelled. For the web it's OK, if you can live with multiple software and hardware bugs. For terminal(telnet,ssh,vnc) access it's unusable as the latencies are in the satellite ISP range (pings >300ms).

Who the hell Verizon markets the thing to anyway? I'm personally not gonna fork $100 to read slashdot and browse porn on the train. My company would if it could also be used for real work, which this POS service doesn't deliver one bit.

My experience

[prisoner]

I bought one of these, along with the pc connection kit. The speed is ok but it still "seems" slow. I had great signal but it takes forever to actually contact the site. Once it starts rolling it isn't too bad but the time it takes (4-5 seconds) to get the transfer rolling sucks. Bottom line is that it's not bad for ocassional use - checking email and whatnot when you're going from place to place but I wouldn't want it as my primary net connection.

Yeah in VT

[bigmoosie]

In vermont Burlington is about teh only area with PCS service ... that doens't help for me who lives in St. Johnsbury and its a 2 hour commute (almost 80 miles mostly little towns with spee dlimits of 35mph) so once your out of your service area you start using extra minutes and get charged for every tower you connect to ... it gets expensive. Tri mode phones up here are god !!!

Unlimited PCS Vision minutes not for use with PC?

[raygundan]

I can't seem to find it now, but Sprint had a disclaimer on their page about using the "unlimited" PCS Vision minutes with a PC. The original wording said that you could only use the unlimited time with the phone itself, not as a data connection for your laptop or whatever. Can anybody confirm if they have changed this?

For $40 Bucks...

[telstar]

For $40 bucks I want Sprint to stop screwing around with their service and stop making changes that complicate things for their users. In the past 4-5 months these changes have taken effect:

• Sprint relocated the due-date on Sprint bills making is more difficult to find the "pay by" date
• Sprint voice-mail no longer states the name of the caller. Instead you get to listen to a verbose reading of their phone number ... adding about 10 seconds to every call
• The voice-mail indicator requires that you stay on the call an additional 2-3 seconds longer than you used to, when picking up voice mail, in order for the indicator icon to disappear on your phone. If you hang up too soon, you'll have to call back to listen to "No new messages" before it disappears.

This is just a sampling of the changes Sprint has made over the past few months. I can't see how any of them were implemented for any other reason than to increase their profits. Additionally, ALL mobile phone companies are guilty of delaying phone-number portability, because they know that once people can leave their network and take their phone number with them it will open up a completely new area for competition.

As his phone feels the /. effect that only few can survive, and yes west exodus is barely holding on!

Hrmm...wonder if you can play counter-strike on this bad boy. Would be cool to get a demo unit and see how well this bad boy frags!

What sucks ass is that we just signed 2 1-year contracts for our cellphone...crap! Oh well though I have been told before that Sprint customer service sucks realy bad and service is very crappy too!

Here is the info from his website.

This document describes how to connect a Linux box to Sprint's "Vision" (3G) network using a Sanyo SCP-4900 and the PCS Connection Kit USB cable.

Id: sanyo-4900 php v 1.2 2002/11/06 02:02:11 natecars Exp

Background:
In my ever-lasting search for high speed wireless internet access, I decided to try out Sprint PCS's new Vision service. They recently dropped their prices, so for $40/mo, I'm getting 300 anytime minutes, unlimited evenings and weekends, free long distance, and unlimited 'high speed' (56-144k) data. The best part is that it's simple to get working with Linux - all you need is the proper USB drivers, and the knowledge to set up a PPP connection. The phone cost me $99.99 (after a $50 instant rebate), and the USB cable cost me $69.99. Note that the USB cable looks like it's identical to the one that Sanyo sells directly for $29.99, if you'd like to try that cable, go to https://store.sanyousa.com/osb/showitem.cfm/Catego ry/24.

First Step: Make sure your kernel has the right options
To use the PCS phone, you'll need to have USB support for the USB card in your computer, and support for USB ACM devices (CONFIG_USB_ACM). The kernel included with recent versions of both Debian and RedHat includes everything you need. Also make sure you have hotplugging enabled, so that the modules will be loaded automatically.

Second Step: Plug in the phone, and watch the drivers load
All you need to do is plug in your phone, and all the drivers should be loaded automatically. Note that I have had a few cases where I needed to reset the phone to get the USB interface to show up. When I plug my phone in, I see the following:

Nov 5 19:35:29 knight kernel: hub.c: new USB device 00:07.2-1, assigned address 2
Nov 5 19:35:29 knight kernel: usb.c: USB device 2 (vend/prod 0x474/0x701) is not claimed by any active driver.
Nov 5 19:35:33 knight /etc/hotplug/usb.agent: Setup acm for USB product 474/701/0
Nov 5 19:35:33 knight kernel: usb.c: registered new driver acm
Nov 5 19:35:33 knight kernel: ttyACM0: USB ACM device
Nov 5 19:35:33 knight kernel: acm.c: v0.21:USB Abstract Control Model driver for USB modems and ISDN adapters

Third Step: Create a dialup connection
Now that you've got an ACM device, you just need to create a dialup connection. The 'magic number' to dial to get a connection to the Vision network is '#777'. So, use whatever method you prefer to create a dialer that will dial #777. On my Debian box, I'm using the standard 'pon' scripts. Here are the config files I use:

/etc/ppp/peers/sprint:

# You usually need this if there is no PAP authentication
noauth
# The chat script (be sure to edit that file, too!)
connect "/usr/sbin/chat -v -f /etc/chatscripts/sprint"
# Set up routing to go through this PPP link
defaultroute
# Use remote DNS
usepeerdns
# Default modem (you better replace this with /dev/ttySx!)
/dev/ttyACM0
# Connect at high speed
230400
local

/etc/chatscripts/sprint:

TIMEOUT 5
ABORT '\nBUSY\r'
ABORT '\nERROR\r'
ABORT '\nNO ANSWER\r'
ABORT '\nNO CARRIER\r'
ABORT '\nNO DIALTONE\r'
ABORT '\nRINGING\r\n\r\nRINGING\r'
'' \rAT
TIMEOUT 12
OK ATD#777
TIMEOUT 22
CONNECT ""

So, I run the command 'pon sprint', wait a few seconds, and then start surfing. I generally get ping times of 300-500ms, and download speeds of 7-12kbytes/sec. Not bad at all, considering it's a connection I can take with me everywhere I go! Note that Sprint also gives you a public IP address, where the rest of the wireless phone connections I've tried have been NAT translated. Note that this service works beautifully with FreeS/WAN as a VPN Client. Well, hope this has been helpful.. good luck getting your connection up!

Yes it does.

[_xeno_]

And I quote from the Agreement for the very plan the story submitter is quoting (the plan I'm going to be switching to shortly for my phone):

Sprint may deny or terminate service without notice where use is in connection with server devices or host computer applications, other systems that drive continuous heavy traffic or data sessions, or as substitutes for private lines or frame relay connections. Unlimited PCS Vision offer for PCS Free & Clear Plans with Vision is: (a) only available with a Vision capable PCS Phone or PCS smart phone device; and (b) not available with Connection Cards, Aircards, or any other device used in connection with a computer or PDA - including phones, smart phones or other devices used with connection kits or similar phone-to-computer/PDA accessories. Sprint reserves the right to deny or to terminate service without notice for misuse.

The reality I got from that section is that basically if you try and use your phone as your primary Internet connection, they'll shut you down. But if you just use the phone occasionally as an alternate method of connecting to the Internet, then they'll probably leave you alone.

Basically, what this guy is doing does go against the agreement needed to receive the "Unlimited PCS Vision" option. But yes, you can get plans that are designed for use with laptops/PDAs, but at around $40/month for 20MB total and $100/month for unlimited access. And these plans do not come with voice calling, or any features related to it - they are purely for Internet access.

Get files to your phone

[strictnein]

If you're interested into getting files to your new Vision phone (and not paying for the stupid downloads that Sprint has) check out their development pages

Not really the greatest resource, but it contains some decent info

Just don't use AT&T to dial ISP

[sprekken]

from a large city... I almost bought a 3Com cellular PC modem card with the 3Com Nok6 cable that connects the pc modem to my Nokia 5165 so that I could dial my ISP from my laptop. This is a bad idea if you live in an area where AT&T doesn't provide analog service (Most large cities)... because IT WON'T WORK!

I don't care really about the connection speeds (9.6K is fine), I just need a damn connection for a simple little application I've made but I don't want to have to pay $40. a month + $100 phone + change provider, etc.. though it looks like I'll have to.

Ugh.

Re:Translating the salesman lingo

[Mr. Grimm]

*disclaimer* I work at Sprint in Retention. Unlimited data is unlimited data. No time restrictions on it, and there never have been even back on the unit pricing. Data is just the non PR term for "Vision". They're one and the same.
