For one, I'd upgrade that Desktop Manager to 4.x, although this won't resolve your issue. Did you enter in the carrier specific APN information as stated on page 1? Did you disable IP header compression?

Alright, I've been playing around with a windows laptop and my 7520 for a bit, and so far this is what I have found:

1. With the desktop software installed and the handheld manager running after a restart, the modem is recognized and will successfully query.

2. Opening up hyperterminal and typing in the same AT commands that windows does gives the same results (logically)

3. Trying to connect to the "S=2" Packetstream number kills the capital "L" of the "NXTL" service indicator.

4. Typing ATDT into hyperterminal yields a "CONNECT" response after which garbage is dispensed. Escaping the modem using +++ a few times gets back to command mode. Again, after doing this the capital "L" in NXTL is reverted to a lowercase version.

After performing items 3 or 4 and then disconnecting the USB cable turns the radio off. Turning the radio back on effectively resets the modem and restores normal functionality.

I tried downloading the Nextel Dashboard software (the updated Packetstream software) but with the same results.

Hopefully with everyone working together (developers and people with close connections to Nextel's tech people), this may be a possibility.

I will try upgrading the desktop to 4. It can't hurt! And yes, i did enter all APN info as stated and removed Ip comp.

ok, now i remember why i dont have the desktop v4 installed. i get an error during the installation of x-thinpro? "An error occured during the move data process: -132"

Any thoughts?

I just got my cingular 7290...upgraded from a 7280. After upgrading the handheld to version 4.0.0.219, and following all of the instructions on this forum for configuring my device as a modem, I didn't run in to any problems. My company already had unlimited data on all the devices, so I guess the cingular tags I needed on my account were already there. The speed is about 115 Kbps, so we are not talking blazing speeds, but to be able to surf from anywhere with Cingular towers is pretty sweet. The only thing now is to figure out how to get my company's VPN to work through the modem or to use the BES to allow me to surf within my companies network. If anyone has any ideas on that, I would love to know. Let me know if anyone has any questions.

I had trouble on the VPN part - It appears GRE tunnel traffic for the PPTP VPN I was trying to connect to is firewalled/unallowed. Or maybe it's just some kind of limitation in the IPmodem implementation. No idea.

Do you use a program called x-thinpro? Could be residual installation files. Delete the contents (or as much as you can) of the C:\Documents and Settings\<username>\Local Settings\Temp directory and try again.

Hello - I just got the 7750 from Sprint. I've been able to use my other mobile phones for a modem on Sprint's network so I'm confused as to why the 7750 won't work. Is this a hardware or BB Software issue? Basically I'm wondering if I should get a different model or wait it out.

7750 is not a supported model. There is no modem in the 7750.

Please read the "Supported Models" section -- you'll see only the 7250, 7290, 7100 and 7520 are the only models that have a modem in it.

Of these models, only the 7100 and 7290 have successfully been used as a modem on T-Mobile, Cingular, AT&T. Nextel has not yet allowed the 7520 to be used as a modem, and Verizon/Bell has not yet allowed the 7250 to be used as a modem.

Old text may not be clear, so to make things clearer, I have now edited:Newly changed into the following:Hopefully this will make it clearer to new users ;)

I'l pledge 10 buck to to get this to work on the 7520

Same.

Interesting - per the specifications, http://www.blackberry.com/products/h...erry7750.shtml, of the 7750 from RIM I was under the impression that the 7750 has the same "Embedded RIM® wireless modem" as the rest of the "compatible" devices.

I have just run into the same problem. It appears no one was able to give you an answer. Were you able to solve the problem?

Technically, a modem doesn't necessarily mean a "modem for PC's". That kind of "modem" already exists in all digital cellphones ever since the first digital cellphone -- it's the only way to do digital phone, WAP, email, or any other type of data inside the cellphone. It modulates-demodulates the analog airwaves (all RF transmissions are analog, they have to be converted to digital) into the digital bits and bytes needed for digital voice reception, displaying WAP pages, HTML pages, emails, etc, on the cellphone screen.

Hope that explains things and clears up the confusion!

For the purposes of terminology "modem" mentioned on this forum means a modem for connecting to PC's rather than an "internal-use-only modem (for digital voice transmissions, WAP, email, TCP/IP stack, MDS, etc, on the BlackBerry itself only)"

Is the data still accurate that an ATTWS 7100g can be used as a modem? If I am using a BES 4.0, do I have to worry about any account settings with ATT?

That's because that folder doesn't have modem drivers. That folder contains virtual serial port drivers. Reinstalling your Desktop Manager software will re-create your modem entry.

You shouldn't have problems with Cingular Blue, but I think 7100g's can only be used on Cingular Orange. If that's true, you have to follow the extra hoops of getting Cingular to add access to wap.cingular or isp.cingular to your account. Try calling Cingular and getting the "Data Connect" plan added to your account, this may be just what the doctor ordered.

However, if you're really on Cingular Blue (AT&T), it should now already be enabled, and you should follow the instructions for AT&T.

To make life easier, you may want to test a non-web-browser TCP/IP application on your BlackBerry (i.e. Verichat Trial), and once that works, it's much easier to get BlackBerryModem working.

I have seen a lot of things on this posting that helped me get to success with AT&T (Blue) and Cingular (Orange), but found that there is a mixed configuration that I required. I'm an AT&T (Blue) account as Cingular moved me to AT&T for some reason to get the best 2000 minute plan and unlimited data access rates.

I was receiving considerable problems setting up my BlackBerry 7100g modem with either Windows 2000 or Windows XP. I could not get any help from AT&T/Cingular. However, persistence paid off. I used a combination of configuration settings and now the modem works flawlessly for both Operating Systems. This configuration was based on the newest BlackBerry Desktop Software 4.0.0.33 and BlackBerry Handheld Software 4.0.0.274 that I downloaded and applied them on 3/18/2005 from https://www.blackberry.com/Downloads...E4F82F9F00E7D4

Here are the instructions for what I did:

Step 1 - Connect Your BlackBerry 7100g

Make sure your BlackBerry is connected by USB cable, and your BlackBerry Handheld Manager is running (just launch BlackBerry Desktop to run it.) This is necessary for using the BlackBerry as an external modem. You cannot use BlackBerry as a modem unless you have BlackBerry Handheld Manager running in the background!

Step 2- Verify Modem is Functioning Properly

Go to Control Panel -> Phone & Modem Options. In the Modems tab, you should see a new Standard Modem (it will not say BlackBerry so do not get confused) on a new port (such as COM3, COM6, COM7, etc.). Click Properties -> Diagnostics -> Query Modem. You should see the following on Windows 2000 (below, “OK” will be replaced with, “Success” on XP if you want to get real technical):

ATQ0V1E0 - OK
AT+GMM - BlackBerry IPmodem
AT+FCLASS=? - OK
AT#CLS=? - OK
AT+GCI? - OK
AT+GCI=? - OK
ATI1 - Research In Motion / BlackBerry IPmodem
ATI2 - Research In Motion / BlackBerry IPmodem
ATI3 - Research In Motion / BlackBerry IPmodem
ATI4 - Research In Motion / BlackBerry IPmodem
ATI5 - Research In Motion / BlackBerry IPmodem
ATI6 - Research In Motion / BlackBerry IPmodem
ATI7 - Research In Motion / BlackBerry IPmodem

Step3 - IMPORTANT SPECIAL CONFIGURATION STEP

Click Properties -> Advanced and add the following extra initialization commands with the appropriate carrier-specific APN Setting (remember I’m an AT&T account on Cingular and therefore am using the AT&T setting):

AT+CGDCONT=1,"IP","proxy"

NOTE: I have seen elsewhere in this forum that the advanced configuration should be +cgdcont=1,”IP”,”proxy” but found I needed the AT and capital letters at the beginning for some reason of the configuration string. I do not get why it was case sensitive as normal modem commands should not matter what case they are in. But, I point out the AT and capital issue for your convenience.

Step 4 - Add a New Internet Connection (some things are a little different on 2000 vs XP but pretty similar so try to follow what I have put here)

2000 - Close the Phone and Modem Options and the Control Panel. Create a new connection with Start -> Connect To -> Show all connections -> Create a new connection; or
XP - Close the Phone and Modem Options and the Control Panel. Create a new connection with Start -> Settings -> Network Connections -> New Connection Wizard.

1. Click Next
2. Select "Connect To The Internet" then Next
3. Select "Set up my connection manually" then Next
4. Select "Connect using a dial-up modem" then Next.
5. Check only the Standard Modem (if prompted).
6. Give the connection a name such as "BlackBerry Modem", then Next.
7. On the next screen, pick one of the following phone numbers, depending on your AT&T/Cingular phone enter phone number *99#
8. Click Next.
9. On the next screen, pick one of the following, depending on your carrier:
If you use AT&T previous configuration information posted in the forum (probably pre-AT&T merger) is:
Username: (blank)
Password: (blank)
THIS NOW APPEARS TO BE WRONG. Therefore you should really use the Cingular Configuration (I know you have half of the AT&T confiruation previously configured if you’re following these instructions. But, just trust me as this works for me on XP and 2000!):
Username:
Password: CINGULAR1

Step 5 – Configure DNS for Cingular

1. Go to Start->Settings -> Network Connections
2. Right-click your BlackBerry Internet icon, select Properties.
3. A window will open. Click the Networking tab.
4. Click TCP/IP Settings and then Click the Properties Button
5. Select "Use the following DNS server addresses:"
6. Enter Preferred DNS server: 66.209.10.201; and Alternate DNS server: 66.209.10.202

Please let me know how you make out or if you found another solution. I hope this helps!

I have the 7290 with v4.0.0.219 with the Cingular service (ex AT&T). I can't get it to regognise the modem through the control panel and it doesn't have the Modem drivers in the C:\Program Files\Common Files\Research In Motion sub directory (it doesn't have the driver folder refered to earlier in this post). Any suggestions?

I worked it out - I upgraded the desktop manager and the modem appeared!

I work for Nextel customer care, it should be possible to use any of their phones as a modem, but you have to call in and request "NOL Dialup" added onto the account. As of January 1st / 2005 they no long list this feature in their wireless web information, so you may have to insist a few times to the care rep you speak with that it is possible to add this to the account. The cost for NOL Dialup is 10.00/mo and you need you own ISP to dialup into...

Otherwise you need to get the Packet Stream Gold which gives you accelerated web access through the modem in your phone, and Nextel will act as your ISP. Not entirely sure this works with blackberries, though I imagine it would.

I have just tested a 7100g on Telstra Australia with the following settings

+cgdcont=1,"IP","telstra.internet"

GPRS works great! dial string is *99#

Excellent to hear.... Did you have to do anything special such as call Telstra to give you access to the "telstra.internet" access point name?

Did you have to enter a username/password when connecting?

You need to subscribe to a GPRS plan first before being able to use telsta.internet APN.

There is no username/password needed for Telstra GPRS. you can put in anything or just leave those fields blank.

I've been successful connecting a 7110g on BES to Cingular (orange) @115K and my corporate VPN software works fine. Thanks for the instructions.

Greetings,

As I posted a while back, I have been successfull in using my BB 7290 as a modem for my PC on Rogers with OS 4.0.0.198. Can anyone on Rogers confirm if they have upgraded to BlackBerry Handheld Software v4.0.0.274, consisting of: applications 4.0.0.219 and software platform 1.8.0.129 and still had modem functionality?

Thanks

MM

Does anyone have dial-up working on a 7100G in the Austin Texas area? I had a nice rep on the phone and she tried finding the following for about 10 minutes with no luck

WIX DATA CONNECT $0.00
WRLSS INTRNT XPRS PAY PER USE $0.00

I know a variant has to exist because prior to the BB I had a $3.99 a month WIX setup that allowed me to use my Motorola V400 as a SLOW CSD modem for serveral years.

My laptop see's the 7100G just fine as a modem and attempts to dial out with a 732 error regarding authentication. I did use the settings listed above as well for the Cingular account and password.

Thanks!

Wanting to use 7100t on T-Mobile as a modem for my Sony VAIO V505 laptop. WinXP Home. Connected via USB.

Using the good info on this forum, I almost had it working yesterday, but the process would always stop during the network registration process. Error 734, I think.

T-Mobile's PDA Support said I must upgrade Desktop Manager to 4.0 and and BlackBerryOS 4.0. I did both of those last night.

Today I called T-Mobile's PDA Support and they said I can only connect using Bluetooth (which my laptop doesn't have). Then, after I insisted they check, they said I *might* be able to use USB. So they talked me through installing the new modem driver (which, BTW, is under the Program Files\Common Files folder).

The error I get now is is 692 - Error opening hardware port - and it comes early in the dialing process. T-Mobile's PDA Support walked me through reinstalling the RIM Virtual Serial Port, but that made no difference. Still the same error.

I read elsewhere on this forum that I may want to revert to BlackBerryOS 3.8.

Ideas? Help? Clues?

Thanks!

I was able to get this to work on the first attempt. Quite exciting.

However, that excitement is tempered with the reality of T-Mobile dog-slow data transfer rates. I've seen better throughput with a 2400 baud modem...seriously.

I would only use this connection if I was out of all other options (which in most cases I almost always have either 1) a WiFi connection or 2) an ethernet connection or 3) a phone jack for the internal modem.

Now this is in Atlanta, I don't know if the performance is T-Mobile-wide or just symptomatic for the Metro Atlanta area. I am in fact using the connection to post this message but it's not a very practical means of connection.

I propose 3 challenges.

1) Using nextel 7520 for dialup. $100 Paypal (so with others this brings it up to over $140)

2) Somehow creating a proximity application for bluetooth blackberrys to mark the desktop redirector/BES server as in cradle. my thoughts are to take advantage of the broadcast signal from the blackberry. Basically I don't want to receive emails when i am near my system but i don't want to cradle the blackberry. $150 Paypal
3) Using bluetooth for dialup or desktop manager synchronization. $200 Paypal.


i know that 3 may not be possible.

Any individual challenge is only valid until Nextel or RIM releases information on how to complete the challenge or for 4 months july 05 (unless extended) . If challenge 3 is meet collection of challenge 2 prize is not valid.

Feel free to contact me with any questions at groups*kb@licensetech.com remove *

Feel free to repost these challenges to other threads that would follow the subject of any of the challenges.

Have you tried recreating your dial-up connection? Seems like the modem or dial-up connection is trying to connect to a COM port that either isn't open, functioning, or non-existant.

The BB OS has nothing to do with this. 4.x works fine.

Does the 'Query modem' function even work on the diagnostics tab?

I believe it's the latency that's killing you. Do a quick ping to Google.com or somebody else and paste it here.

If I only had a Nextel plan... Mail me your Blackberry ;)

I was able to setup the connection using my Blackberry on Cingular, but still couldnt get access (error 734). I contacted customer service and this is what I got.

"You are requesting to add the Wireless Internet Express (WIX) option to
this line also. I would like to advise you that all of the features of
Wireless Internet Express (WIX) are included in your Data Connect
package. If these features are added, you could be charged at the pay
per use rate of .03/kb for internet access, instead of utilizing your
data connect package rates. When we add data connect packages to
customers accounts, we remove all Wireless Internet Express (WIX)
features."


Looks like I will be unable to get my Blackberry to work unless I'm willing to pay extra for something I should already have. Any ideas on how to get around this?

Well I hooked up my 7520 to my laptop and was able to query the modem but it would not dial out so I called Nextel tech support and explained my problem. She was not sure what was wrong so she placed me on hold for 5 min or so then came back and told me “at this time 7520 is not supported as a modem”. Then I asked if they ever would and she just kept saying at this time it’s not supported. So this gives me some hope that in the near future maybe they will.

YESS! I should have guessed to delete and re-create the Network connection for this. I did that and it worked. Certainly slow, but once in a while it's better than nothing.

Thanks!

I too had many problems using the Blackberry as a modem. I had the "734" error. Here is what fixed it for me:
1. Change the initialization string on the modem properties to:
+cgdcont=1,"IP","WAP.CINGULAR"
2. Change the user name of the Blackberry connection in Windows to:

3. Keep the password as CINGULAR1.

Doing this fixed it for me.

DISCLAIMER: I still haven't found out if it will charge you for data rates this way. We'll see...

Update on the Nextel side of things...

Not sure if anybody has experimented around with this, but by swapping the SIM card from the 7520 into an i730, the i730 will connect to the Internet using the S=2 dial string. From what I can gather, this means you do not have to add PacketStream Gold to the account. Getting the Blackberry to connect seems to be a different issue altogether though.

I am using this on a Mac (OS 10.3.8) and attempting to get the BB to talk using the modem script provided at http://www.osxhax.com/archives/000007.html. This works fine for the i730 but as what seems to be tripping up the Windows users too, the BB just doesn't want to talk to the outside world using the USB port.

If anybody else has a Nextel phone they can try their BB SIM card on, I'd like to know if the PacketStream service is enabled by default for all BB accounts (I know I'm not paying an extra $55/month in addition to my BB service), or if I just happen to be a fluke.

Thanks for the great advice!

I completed the whole process in less than 30 minutes from start to finish. I downloaded Desktop Manager 4.0, then followed your directions, and BAM! it was done.

I am posting this logged on via my blackberry right now!

Keep up the great work.
