I finally got around to figuring out how to get this to work this afternoon and I thought I'd share in case anyone else is looking to get this working as well.

Current system:
Dell Inspiron 8200
SuSE 8.2 Professional
Kyocera 7135 Smartphone hooked up via COM1: (/dev/ttyS0)

First, in order to use the phone as a modem, you must launch the FaxModem program from the main menu of the phone.

To set up and use the phone as a modem...
Essentially, I went through YAST2 | Network Devices | Modems. It detected an AT modem attached to COM1. Either configure the one it detects or add a new modem and use the following settings:

Modem Parameters
---------------------
Modem device : /dev/ttyS0 (although if you have it hooked up to a different COM port, this value will vary)
Dial Prefix : none
Dial mode : Tone
Special Settings : Speaker on - No, Detect Dial Tone - Yes
Details : Baud rate - 115200, Init 1 - ATZ, Init 2 - AT$QCMDR=3, Init 3 - (nothing)

Select Internet Provider
-------------------------
Custom Provider, add USA.
Select "New" and enter information for Verizon Wireless (which is who I go through)
Provider Name : Verizon Wireless
Phone Number : #777
UserName : xxxxxxxxxx@vzw3g.com (where xxx's are replaced with your phone #)
Password : vzw

Connection Parameters
-------------------------
Dial-on Demand : I said No, but you may want to say Yes to enable this feature
Modify DNS : Yes
Stupid Mode : Yes
Firewall : Yes
Idle timeout : 180

You can leave the IP details alone.

The next page should show you both the new modem (ppp0 on mine) and the new provider (provider0 on mine).

Click Finish and the configuration will be written. If the system asks you if you want to configure mail, choose No if you are simply setting up an Internet connection. I believe this is for KMail if you are using it. I'm not, so I choose simply to abort at that point.

To make the connection, start KInternet (although KInternet wouldn't actually successfully connect, for some reason). Once KInternet is started, open up a shell, change to user root via "su" and then issue the command "wvdial". It should connect and within a few moments, you should be online. Honestly, I haven't done enough testing to be sure that KInternet is even required. It may have just been coincidence on my machine that it worked only when KInternet was running.

I should mention that you must have the "wvdial" application installed before you can run it from the command line.

Happy surfing!

You'll have to excuse my complete n00b-ness at this...I ended up getting things to work and I wasn't entirely sure how.

Wvdial operates completely independently of KInternet. I still have not been able to connect via KInternet (of which the configuration options are posted above).

I can eventually connect via "wvdial", but it seems rather hit or miss. Sometimes it will try four or five times to connect and it will fail. Then suddenly it will go through. Just for the sake of completeness, I'll post the contents of my /etc/wvdial.conf file so that you can see the correlation to the settings I entered into Yast for KInternet.

[Dialer Defaults]
Modem = /dev/modem
Modem Type = Digital Modem
Baud = 115200
Init1 = ATZ
Init2 = AT$QCMDR=3
Init3 =
Area Code =
Phone = #777
Username = xxxxxxxxxx@vzw3g.com
Password = vzw
Ask Password = 0
Dial Command = ATDT
Stupid Mode = true
Compuserve = 0
Force Address =
Idle Seconds = 180
DialMessage1 =
DialMessage2 =
ISDN = 0
Auto DNS = 1

(obviously, replace the xxx's with the cell number)

So, my next question (ah, yes, here again comes the n00b-ness)...is there a reason why wvdial is hit-or-miss? Most times, it calls the first Init string (ATZ), pauses, and then issues a quit signal (ATQ0) before ever calling the second init string.

For now, it's not a big deal to call wvdial 3 or 4 times in a row before getting a connection...but if there is something I am doing wrong that I can correct so I get a connection the first time, that'd definitely be something I'd like to correct!

TIA!
