First off i have not been able to get this feature to work yet, at first it was connecting me and then kicking me off at the verify username and password. I am using the devil Cingular. But now i am getting a new message it is telling me that the Device in in Use and cannot connect. I have no idea what it is doing this all i have running is the Desktop Manager.


Please Help Me i would love to figure out how to do this and with Cingular if i have the unlimited data plan with the 8700 am i still going to have to pay extra for the coverage. Also my BB works on EDGE network is that a problem?

I just need any help i can to get this thing to work on a modem. I am going on a Bus Tour and hope to have it working in case we need the internet on a laptop for emergancy emails, I work in Politics. Please email me at if you can help walk me through how to get it to work and get around this Device in Use stuff. At this point i have deleted the BB modem. So ready to start from scratch

I had no problems when I followed the instructions at the top of this thread.

Am using Rogers in Canada so your use of Cingular could be an issue. If I recall correctly a few idiosyncracies. You need to remember to run your BB Desktop Manager and of course set up a modem on your PC. Do check that you followed Mark's instrucdtions. With Cingular Blue, Mark's note says blank Username and Pwd. With Cincular Orange, there are other settings. Make sure you got this correct.

I have a 7290 Blackberry. I have followed the directions on your forum as to how to connect. I am able to get the Blackberry to connect as a modem, but when I try to go to internet explorer to surf the web, IE doesn't recognize the online connection established through the Blackberry. Any help on getting over this last step would be appreciated.

Hi... i'd like to ask, for this to work, do i need to be on the data plan from bell mobility (canada) or just their black berry plan?...

cuz the bb plan is only $60 whereas the other data plan is $100.

i'm told by the agents that i need to be on the $100 plan...

please advise...

I followed the instructions above in regards to using a Blackberry 8700c as a modem via the Cingular network. Everything worked just fine, however, my 8700c is Edge compliant and is on Cingular's Edge network. When using the internet from the handheld I get DSL lite speeds. 70-90 kbps average, and maybe 120 or so kbps spikes. Regardless, for a handhald it's very impressive. When using the instructions above I'm able to use the 8700c as modem for my laptop, but, it's only dialup speeds. What do I need to do different to get the Edge bandwidth?

I registered specifically to thank you for this tutorial. I use a 7290 on T-MO, and following your tutorial, I connected on the first try... at 115kBPS with minimal signal.


Thanks again.

Ok - so I have a 7250 with 4.1 code (don't ask)... doesn't show EVDO yet (service book issues?)... I have had some success with the modem. I do connect and get and IP address:
PPP adapter BlackBerry Modem:

Connection-specific DNS Suffix . :

But I can't ping anything... I'm guess this is probably a setting on the BES server - but since I work for one of those large corporate type companies finding that person who manages the BES servers is proving to be difficult. Can anyone confirm that this might be the problem - or am I missing something.

btw - I dial with the *777, and user name is @1x.bellmobility.com pw is voicemail.

thanks!

hey guys, im new here and i found a bundant of info on this.

i jus wanna throw in some info for you guys. i did read the whole 14 pages but cant remember if im reposting these info

first off i have the 7105T(for tmobile) and 7100i(for nextel)

for tmobile
using that strings, i get ppp error

so i tried
worked fine.

i just got off the phone wit tmobile BB customer service and they told me that the BB unlimited data plan will cover for my data usage. wooohooo!! lol

now, for nextel. i cant query the modem but i will see if in the near future when i get time to mess around wit it.

good luck!

I just got off the phone with Cingular, they said I must switch from the $44.95 Unlimited Blackberry Connect plan to a $79.95 plan. Has anyone found a way around this?

Hi,

I've used the settings recommended on this thread using the extra init settings and then *99# and the modem was recognized just fine when I plugged into my USB port.

However, now my computer doesn't even recognize a modem exists when I plug in the 7100t. I have not changed any settings on my computer at all. Still does not recognize after I open the BB Desktop Manager program.

Any suggestions of what I need to do?

Thanks!

p.s. Just want to say all of you guys have been great!

I use shark modem www.mobishark.com. I connected just find without the 77.95 plan.
I thought the 44.95 was unlimited because I am with cingular also.

Signed up with Cingular yesterday to use my 8700c as a modem. Could not get my laptop to recognize the device and kept getting error 633. Cingular tech support trying to recreate problem and come up with a solution. Any ideas out there?

The correct init string for the Blackberry 8700 when using T-Mobile (tmobile) as a modem on your laptop is

+cgdcont=1,"IP","wap.voicestream.com"

refrence:

I also posted this in the 8700 general discussion.

Keywords:

8700c, Tmobile, T-Mobile, Modem, 626 Error,

03-05-2006 12:05:21.156 - Send: AT+cgdcont=1,"IP","wap.voicestream.com","",0,0<cr>
03-05-2006 12:05:41.156 - Timed out waiting for response from modem

I was able to get my 7105t to work using tmobile. At first I was receiving error 734 but that was because i was missing the + in the init string. So, be sure to have the following in your init string (just as specified by this FAQ, i just missed it when i did copy/paste)

Init String: +cgdcont=1,"IP","wap.voicestream.com","",0,0
Phone Number: *99#

I also had problems originally with 'standard modem' not being in my list of modems. I removed the desktop software and reinstalled and that created the modem.

I am running the HK CSL 4.1 on the bb and for desktop manager.

Has anyone gotten the modem to work on the CSL network? I know the APN settings are:

APN: hkcsl
Gateway: 192.168.59.51
Port: 9201

but I don't know how to put the port or APN into the initialization string (if required). I also don't know the username and password. Right now it seems to connect but fail at login. I get an error: "Checking network protocol connections....TCP/IP CP reported error 736: The remote computer terminated the control protocol" - during "registring your computer on the network. Any suggestions!?

I was getting the 736 error as well, and this fixed it for me:

Thanks, all! This will certainly improve the quality of my life when I'm on the road this weekend.

No luck as I am using IP and not DNS for the gateway. Can someone explain what the syntax is. Should I need to add the port I have for the APN? I tried other init strings and I just get an immediate error (don't even connect). THANKS!

Spent two hours trying to set this up the way listed here...
then gave up
bought sharkmodem, and was running in about 3 minutes... dont waste time!

Has anyone gotten VPN to work over AT&T/Cingular?
The instructions at the beginning worked awesome. I can surf with no issue.
My VPN (PPTP) will not connect though.
Any thoughts?

You need to probably setup the APN. I don't know the settings but this lets you have IP access to the internet for things like VPN.

Have 8700C with Cingular/ATT. Have company BES. Followed setup instructions and am receiving this error when trying to connect:

Error 736: the remote computer terminated the control protocol

Any ideas on what's causing this ? thx

i too am interested in the answer to this question ? is it possible to get more than dial up speeds when using the BB 8700c on cingular with edge speeds ?

With 'WAP.CINGULAR' in the init string, 'ISPDA@CINGULARGPRS.COM' as the userid and maximum modem speed set to '921600' in the connection properties I'm getting 156Kbps per the cnet.com bandwidth meter. dslreports.com reports slightly less but still more than double dialup speeds.

Watching NetPerSec on the interface I've seen bursts to 235Kbps.

8700c Cingular Orange/EDGE with a -64db signal strength reported by alt+nmll

PS: No blocked ports that I can find. SSH, FTP, Telnet, VPNs all seem to work fine.
