====How to ...=== - HTC Tornado

Open a topic in which who has asked you to do so without the need to open a new topic.
So, first question: would be how could i make you can surf the internet on mobile but at the same time to be called?
T'ks.

You must be talking about browsing via GPRS, and that depends on your provider.
I believe, it's technically impossible to have a call and browse web via GPRS at the same time. Some providers offer work-arounds as additional services, for example if you got a call, GPRS connection gets interrupted and continues after the call.
So if you need this badly, check your provider's additional services, or surf via Wi-Fi

Another opinion?

In Russia most large federal operators claim that calls can be made and accepted during a GPRS/EDGE session. On my Tornado I always have EDGE icon on (that means I'm registered in EDGE network) and answer incoming calls without problems. The only time when I can be temporarily inaccessible is the moment when the phone is downloading something. E.g. any Forex program that is downloading data continuously. When I exit it - everything's fine again.
But I partially agree with Pasimetes that it is provider-dependent. It may work worse with some regional operators.

It's part of GSM specification. Check this:
http://en.wikipedia.org/wiki/GPRS
search for 'class B' (i got no idea where i found it's 'B', it was long time ago, maybe here:

IM with GPRS

Hi.
Im getting my Blue Angel (XDA IIi) with my next paycheque. But i really want IM with GPRS. I'm thinking about going dual Sim with a T-mobile card just for the webnwalk plan, because O2 charge stupid prices for WAP (£3 per mb)
But i realised you can't use IM with most GPRS providers because the ports are blocked to stop other forms of non profit making communication. So what about setting up your home pc as a terminal service server, and then using termincal service client to access it and use MSN from there.
I e-mailed T-mobile asking if termincal service client was allowed and here was the (relevent part of) the response:
"Using our webnwalk priceplans you would be able to use the terminal service client on your phone in order to access other pcs. The GPRS usage would come out of your allowance any time that you used this service."
Not having my XDA IIi, i don't know if this would work, so could someone test it please.
is this a good idea or should i have stuff thrown at me for even thinking it?
Thanks.
Erm.......... you can use IM on T-Mobile GPRS... I do most days.
Either the supplied Messenger ir Agile Messenger.. works a treat.
I moved from O2 to T-Mobile cos they had no decent GPRS uage plans.. now I get unlimited.... it's great....
Charlie Grillo
another part of that e-mail:
"In terms of MSN messenger, this would not be allowed as part of the terms and conditions of the priceplan. These state that certain things such as VOIP, Messaging over internet and Internet Streaming are not allowed."
Are you on contract by any chance?
TS
I am not familiar with T-Mobiles Terms / fair usage policy, but it seems strage you can use terminal services and not msn messenger - I would have this checked out!
I know that TS works perfectly on the XDA 2 and above, if that helps.
IM on GPRS
Yes, I'm on contract - not PAYG.
I read T-Mobile's T's & C's, but messaging isn't mentioned.. it contains this guff..
To ensure a high quality of service for all our customers, they are not to be used for other activities such as (but not limited to): modem access for computers, internet based video/audio streaming services, peer to peer file sharing, internet based video download and internet based telephony.
hmm.. modem access - a bit restrictive, but as I can't get the damn thing to connect and dial when used as a modem any more it's not a problem (I wonder if they crippled this in their last ROM upgrade as it worked perfectly before...)
bandwitdth
in theory this is possible, but theres no chance of running terminal services/remote desktop from the blueangel over gprs...
the connection is not quick enough.
over wifi its fine but not gprs.
good point
I have done it with wi-fi and 3G - if you are in a 3G area (ha!) you should be OK.

Possible to use Kaiser as an Analog Modem?

Hi All,
I posted a similar question before without too much response. So bear with me as I repost it here in this forum as you guys seems most knowledgeable.
In where I live, GPRS data cost an arm and a leg. They charge you something stupid like 10 dollars for 12 megs, WITHOUT the option of purchasing an unlimited plan. What I'm trying to find out is is it possible for our Kaisers to act as an analog modem so I can tether it to my laptop and dial-up to a local ISP? Sure the speed would be terrible, but at least I'll get connectivity without incurring tons of data charges.
Any insights would be greatly appreciated

It would really suck if you're moving such as on a train or such because this kinda of data doesn't handle tower swapping.
It should be possible, depending on your phone provider. I know at&t used to allow it, but it's unavailable with any new plan now, for instance.

Hm... interesting. Technically my phone provider can "dis-allow" their customers from dialing into an ISP using a voice call, but in reality can they really prevent you from doing so? I mean from their end its just any voice call right?
But I digress. Does anyone know how I can set up something like this in WM6? I tried doing the following :
1. Create a new Connection
2. Select "Cellular Line" as my modem type
3. Enter the phone number of my ISP
4. Connect using this new connection
But it fails, saying that it got a problem establishing the connection. At first I thought it was failing to establish carrier with the ISP, but later I found out that it doesn't even dial out but changing the number to my home phone number.
Any ideas would be appreciated.. thanks!!
Actually, there is a circuit you can build, for the electronically inclined, that will connect the headphone/mic ports on the kaiser to the 2wire hole on your laptop, enabling you to use your minutes to DIAL aol or msn or whatever.

Would that be akin to using a mini usb to rj11 adapter? That would certainly be doable! However, I would imagine some drivers needs to be installed. Say, for the WM6 device to act as a modem and for windows to detect it as a modem.

I'm not sure how it's done, but my provider certainly does block it unless one is provisioned.
On my Sony Ericsson t637, I can ISP dialup on one sim that is provisioned on the monthly plan, but on the other cannot dial through. If you hand dial it, you can hear the other side's modem for fax (for example), but if you try tether dial for instance, it doesn't work. Either sim does not contain any network setup information and it's all on the same phone.

That's very interesting.... the fact that if you hand dial you hear the other side's modem but if you let WM6 dial through one of its connection setups you won't be able to connect.
This leads me to think it might be a software limitation. Any other thoughts?
I want to do this too and have the same issue of it not dialing. But if I hand-dial the number it connects (well, I hear the modem sound). Would it be possible to setup windows to work off those sounds? So instead of dialing, it will just send authentication information. Or dial without dial tone, then you hand-dial it on the cell, and route the "audio" to the modem?
It worked for me
Hi everyone
I use T-mobile in USA, I have the myFaves plan, it allows me to call 5 numbers of my choice for free. One of these numbers is a Dial-up number that I use to dial out and connect to the internet. However it takes about 20-30 attempts before I make a connection (or sometimes it connects in just 2 attempts).
The point is, I've done it and it actually works. All you need to do is go in 'Connections' and add a new connection. Select 'Cellular Line' and specify the phone number you wish to dial.
I would love to use this method of connection since its free, but the time it takes to connect is very frustrating. I came here looking for some free software that would allow the voice call to be easily recognized as a data call so that I can continue using this facility.
I called T-mobile a while back and asked as to why it was so inconsistent, the cusomer representative replied saying 'You are getting away with it, it's not supposed to happen'. He said that they needed to enable CSD for my line for it to actually work. I had the CSD inactive according to him. I argued that I used voice dialing and not CSD, he didn't agree with me.
Lets keep this thread active and search for a solution, let me know what you guys think.

That's very interesting! I have followed your steps exactly as above, however I can verify that mine doesn't actually dial out. Have you tried substituting your dialup number with your home phone number? That way you can verify at which stage the failure happens. For example, if your home phone rings, then we can conclude that you've managed to make WM6 dial out (which is further than what I've got), which most likely means it fails at the connecting stage.
That fact that I couldn't even get WM6 to dial out makes me think its a software issue more than a network limitation.
I think there's a problem with the Analogue CSD Modem on the TyTN II.
I've been trying to get mToken (http://www.choung.net/mToken/) to work as a simple VT100 async modem connection over the GSM cellular modem and have had no success. Works fine on my other WM5 device (XDA Orbit) using the same SIM card.
As another test I tried getting my ISP connection working over the dial-up Cellular Line (GSM) using start->settings->connections->connections and using then 'cellular line' option under modem selection. Again no success on the TyTN IIl. Again this works perfectly on my other XDA Orbit device.
I have a case open with HTC UK who are still investigating the analogue modem problem on this device.
There's another thread relating to this here:

I can also dial out to any analogue phone no problem using the 'cellular line' modem. The trouble is the HTC's modem is not able to establish a connection if you have an analogue data modem at the other end - it just hangs indefinitely.

Interesting... the problem of not being able to dial out seems more and more like a software problem. In particular, it looks tied to the Radio ROM since I'm on the 1.27.12.17
I'll try some other Radio's and report back the results. zoggo, if you don't mind, please tell us what version of radio are you using. Wouldn't hurt to let us know which rom you're running as well.

The topic becomes more and more interesting;
now i have an idea - to connect an old gsm phone to my linux server and configure it as a dial-in server/gateway, with free data plan between my Kaiser's SIM card and my server's one... This way i will have 500 free minutes of internet every month
The problem is...i don't know how to do it ...yet

I have just tried the 12.32 radio and I'm still not able to dial out. Just to clarify, I couldn't even get the connection to dial out.
So this means something other than the radio rom is allowing zoggo and svilendotorg's kaiser to dial out to an analog number from a connection. If you dont mind zoggo, can you tell us what ROM you're running on? I myself am running on dutty's v3 final.

Thank you all for the feedback, I was on phone with the T-mobile Customer care (level 3 data) today. According to this very knowledgeable person, it is 'supposed' to work and we are 'supposed' to connect without any problems.
This also goes with the fact that there wont be any data call charges if we use the dial-up connection. However we will be using our voice minutes, depends on your plan.
The representative explained to me that CSD was only used for incoming data calls, like fax etc. and assured me that I did not need CSD for it to work properly (he proved my point). T-mobile offers CSD option for additional fee every month. I also told him that I was able to connect many times before, but the connection was inconsistent (30 attempts etc.).
To shinji1: I used Q-Mobile 1.1 with radio ROM 1.27.12.32 and was able to dial out properly (In fact, I personally think that this is the best radio ROM for this purpose). Currently I use dutty's v3 ROM with the same radio and was able to establish a dial-up connection many times before. You better flash to these ROMs; there is no tweaking involved, just flash and try to connect.
The mToken utility looks very promising. I'll tinker with it later and let you guys know my progress. As zoggo pointed out, this indeed could be yet another HTC software problem (or even the new windows mobile problem), lets hope they solve it.
Finally, I noticed that I am able to establish a connection on some days and failing to do the same on others (no matter how many times I try). So if its not working for you, try connecting again after 2-3 days? Its just a hunch, but its an observation I made.

Any way of knowing if data is coming through 3G or WiFi?

Pretty self explanatory this one - is there any way of knowing whether your mobile internet connection (3G) or WiFi is being used in, for example, a browser session? Just don't want to make the mistake of looking at YouTube on the phone, meaning to use the home WiFi, and end up using my 3G by accident, and paying through the nose for extra feed.

The icons on your task bar should indicate if you have a active data connection.
Or, you can use Spb Wireless Monitor (which you need to purchase). It produces reports telling you which software uses which connections and the amount of data transferred.
In a discussion I had with HTC Tech Support, they told me that wifi, when enabled, over-rides the cellular data. I'm not sure if this just applies to the settings or always. Hopefully, someone can provide a definitive answer.
Yes that is correct, if WIFI is enabled you WILL NOT have a cellular data connection.
Umm. There is a wifi icon in the taskbar o.o and a signal icon also.....whichever is there means it's active and if wifi is there, your data will not be active, only wifi.
What all you are saying is true but some applications still use the data network even if wifi is turned on and connected it seems. I have the same issue(i don't have a data plan with my fuze since my college has wifi everywhere). But things like weather and other native apps on the phone will just turn on the 3g network and stat using data instead of wifi.
if a device is transfering data over gprs/3g whatever
it show arrows moving in the signal str icon
otherwise it use wifi
Applications can choose to use a certain connection if they are programmed to do so, windows only gives each one a type of 'ranking', the fastest connection having the highest ranking and being the one an application is to use by default, but the application can override this and choose whatever connection it likes. This ranking is called the "Interface Metric" if you'd like to learn more about it.
There's an HTC program called 'bytecounter' that monitors the SMDx: ports in the system, which are the ports the system uses for data.. in bytecounter you will see the values increase if an application is using data over cellular network. let me know if you'd like me to upload it.

Well that was the kind of answer I was looking for, and is particularly pertinent in my case, as my connection through my mobile provider is about as fast (or maybe even faster) than my fixed line connection at home. A rather bizarre situation, but such is the advancement of Australian broadband infrastructure.
The last couple of times I have used it, I have taken to turning off the phone connection so that only WiFi is running, and then using the internet. It would be good if you can upload the byetcounter program, seems like a free (?) version of the software programatix mentioned.
Here ya go!
Maybe this is just me, but when I try to unzip that file, nothing comes up....?
lol, i always forget to remove the hidden attribute.. let me go ahead and fix that..
Edit: fixed
Newer Windows Live (including the one that come with Touch Pro) will always dial-up the 3G/GPRS connection when checking for email in Messaging. But if you are checking in Windows Live, most of the time it doesn't dial-up but sometimes, it does.
So far that is the only program that I know of behaves like this. I contacted Microsoft regarding this and they keep asking me to contact my celular provider for help. In other word, they are not helping (or do not understand the problem).
Anyway I solved the problem by changing the Connections setting to "My Work Network" for Internet. The catch is, if I really want to use 3G/GPRS, I'll have to change the setting to my celular 3G/GPRS connection.
Or you could use the nodata application from modaco and disable whenever you like the cellular 3g connection just to be sure you are using wifi.When you are away from wifi networks you can in a matter of 2 clicks reenable the cellular 3g connection...

Best SIP software for HD2

Hi,
Could you please help me to find out best SIP software for HD2. I got PortSIP for my HTC HD2. It;s working very well on wifi connection. But not working at all on t-mobile UK 3g network. I get registration failed error. I just realised that PortSIP doesn't initiate the data connection at all. SO getting same message even though not connected to internet. My voip provider is actionvoip.
Any suggestions....
yes portsip does not initiate the 3G/data connection. But there is a work around. Open a web browser or any application that uses data and after connection has been established start portsip then it registers successfully.
I use Actionvoip on 3G without any problems.

Skype is no SIP-software.
VoIP might also be blocked by your VoIP-provider. I use VoIP for my company and we had the problem that we could only sign in from the provider's own network. They didn't allow external connections to their VoIP-servers.
After we had some discussions on the matter we received a workaround, so we can use VoIP from anywhere in the world and customers can call us on the same number, where-ever we are
don't worry
try FRING for windows mobile.. its supported SIP .. WORK PERFECT

[Q] silly settings question for foreign travel

hi all
so I am going out of the country later this week and had a simple silly question. I want to be able to use wifi on my phone for late night email checks. I do not want to accept calls or send text or use any data over the network.
are these the settings I need:
wifi - on (duh!)
mobile network - off
data roaming - connect to data services when roaming - off
Is there a setting for roaming for regular calls? I do not see it. note this is with a rooted inspire using rcmixkingdom.
thanks

I'll try and answer your questions, but I would still recommend you contact your mobile provider and confirm first. This is from my personal experience.
BE PREPARED ... THIS IS A LONG REPLY
Whenever you leave your service area, the area covered by your mobile provider's network, you enter what we call "roaming." Two things can now happen. Either your phone will not work at all in terms of calls or data, or everything will work. It depends on what agreement you have with your provider. With me, for example, I had long ago called my provider and asked them to NOT allow my phone to operate if I went "roaming." Then, suddenly, when I visited the U.S. last week, I realized that my phone wasn't working and remembered what I had told my provider. A quick phone call to them corrected the issue.
All that being said, if you are set up to roam with your provider, you need to consider a few of things.
One, you need consider where you're going. If you're in Canada, and you're traveling to the U.S., roaming charges may be somewhat expensive. If you're doing the reverse, visiting Canada from the U.S., the same would probably apply. However, if you're going overseas, your roaming charges could be quite expensive, as much as several dollars per minute, depending on the country. Data can also be expensive. For example, with my provider (Rogers - Canada), I have 500MB of data with my monthly plan; however, when I visited the U.S., my plan no longer applied, and I would be charged 3-cents per KB, or a whopping $3.00 per MB. I ended up buying a 10MB extra service fee for $10.00.
Okay, let's consider what you want to do.
If you only want to use WiFi, it will work perfectly if you have the WiFi name and password (if applicable). If you do NOT want to be able to take calls, send texts, or use data, you MUST TURN THEM OFF. Keep in mind, too, that certain programs may automatically access Data for up-dating, such as weather, stocks, sports scores, currency exchange rates, etc. You can turn off this automatic function, which I would suggest. I don't know exactly where this function is on your phone, but you'll have to check it out. This applies to the SYNC function as well. Turn OFF sync to make sure it doesn't accidentally access Data.
Now, for your other question re local phone calls. Once you leave your service area, your phone either works, or it doesn't. There is no other choice. If you don't want to accept calls from home, or make long distance calls, then you have to turn off roaming. If roaming is off, you cannot make local calls either.
Also, keep in mind that if you did make local calls, they would all be considered long distance because, as far as your provider is concerned, your phone's area code is static. If you leave your area code, ALL calls become long distance even though, if you're in another country, and you only want to make a phone call across the street, it will still be a long distance call. Think of it this way, billing begins the moment you press call on your phone, yet in this case, that call effectively begins from you home area code. Therefore, to make a call across the street, it would be identical to making the same call from you home, plus roaming charges.
There is one work-around for the local call issue. You could buy time from a local provider in the country where you will be travelling. This may end up being quite inexpensive. Think of it as a pay-as-you-go plan, if they offer it. So, you would simply remove your existing SIM card and replace it with a new one from the provider in the new country. Use it for local stuff. It may even include data, who knows?
When I visit China, which is rather often, I have a "pay-as-you-go" SIM card which I have with me when I visit. I always keep a balance on the account so they don't cancel it. Then, when I arrive, I make the SIM switch, and voila! Cheap local calls.

If ALL you want is data for email and internet, turn airplane mode ON (I use a power widget to have this close at my fingers, but you can long push the power button and the option is there as well as in menu>settings>wireless & networks) then turn wifi back on.
Airplane kills all radios, then you have the option to turn wifi only on (specifically for those airlines that provide wifi).
thanks guys! I figured I was going to call AT&T today to make sure but stealthpsycho - airplane + wifi will work wonders. I just tested it out at home and it is beautiful I am going to turn off roaming by calling just to make sure as well. In case I need to reboot and forget that airplane mode is not on.
thanks again!
Went to Vietnam a few weeks ago. Turning on airplane mode and then turning wifi back on does the trick you want.

W00t! I gots a thx!!!
You're very welcome. I use this trick a lot at the school where I work, b/c I have no cell signal and I want to prevent cell searching. It's also a useful trick if you want to install market apps that AT&T blocks (I.E. PDAnet)
Easy way I go to Japan all I do is take out the sim. Wifi on.
