Dual-mode phones (like some Blackberries) can use a wireless LAN to make a cellular phone call and switch to cellular when WiFi is out of range. My understanding is that in order to do this, you need not only the hardware/software, but your carrier has to support it (supposedly only T-Mobile is offring it in NA).
However I read somewhere, that with certain software like BeWip (http://www.bewip.com/en-us/info/default.aspx) the Kaiser can do it with any carrier.
Has anyone tried this? Can it be done?
Noone tried this yet?
Hi all,
I've got the following problem with my XDA Diamond (O2 Germany).
- To establish a connection, first the 3G connection is enabled. After the 3G connection is up, it switches to HSDPA ("H" icon).
- Now everything works fine, no latencies and fine transfer speed.
- After a certain idle time (surfing...), the H disappears again and is exchanged by the 3G.
- When I try to download data again, it switches back to "H".
=> Then, huge latencies occur (up to 1 min. before data are received), the connection speed slows down dramatically or no more data is received at all.
I first thought of issues with my ROM (Bepe 0.99) or my RadioROM (.05). But after flashing to Aztor V7 and RadioROM .08, I'm afraid I have hardware troubles as the problem persists.
Now my questions: Did anybody here have the same problem? If yes, could you fix it? If yes, how? ;-)
Would be nice if you could help me. It would be really annoying to RMA the device...
Thanks for your help in advance!

eypostel
That could be because you device disconnected from the net (thus it switched from H to 3G), and it take time for it to reconnect to the net.
Thanks for your hint, but I think this behaviour is not normal...
Even the connection cold start (establishing 3G connection, then switch to HSDPA) is faster and before, the connection was working fine:
When in 3G mode the connection was required, the icon changed to "H" within one second, and the data transfer started immediately.
Now, it takes about ~30 s before the first life sign, and then data reception is not even guaranteed.

Thx prodigy7, this topic exactly describes my problem...
I have a question regarding this HSDPA idle bug. Turning off HSDPA should bring relief, but my MDA Compact IV does not have the HSDPA-switch. Can anybody have a look in their registry which values are changed when HSDPA is switched off on an XDA or HTC device?
It is easy, simply save a copy of the registry with PHM RegEditor before and after the change. Then compare both files with a file comparison editor (PSPad or TotalCommander for desktop PCs does the job).
This is so ridiculous... I have bought a HSDPA-device (Touch Pro) because I wanted to use HSDPA a lot... and it doesn't work at all... this was my first and last HTC device... I have invested 600€ for a piece of crap.
The Diamond does HSDPA just great, however your service provider must support it. In the UK T-Mobile supports it on their Web 'n' walk Plus and Max services. If you have normal web 'n' walk you can see the H and connect using HSDPA but its throttled.
Nothing to do with the device, just the service provider. It also depends on coverage. For example, when at home I get a H with 2 bars. When driving to work I loose that and get 3G and then eventually just G. Because my provider doesnt have HSDPA coverage where I work.
To turn HSDPA on and off easily use a cooked rom, i use Duttys. Very close to the original and tweaked just a little.
Did you read the german thread linked above? I guess not because what you wrote is wrong.
It is correct that the problem only exists if you use htc devices in the O2-HSDPA-Network. But: the problem only exists with HTC-devices in the O2-network. I am able to use any other (non-HTC) phone that supports HSDPA with the same sim-card successfully in the O2-network. And I am also able to surf using HSDPA with my HSPDA-Surfstick in the O2-HSDPA-Network. This means: the problem is not the network, it is the device (=HTC).

If it was that simple then none of us would be able to use HSDPA on our TD, but most of us can. I can use it on my TD on Orange in the UK and other networks including O2 when I am roaming in Europe and, for that matter South Africa (not sure about Germany). So the problems probably lies with the interaction between them, rather than solely the "fault" of one or other.
Seriously, sometimes people can be a bit absurd. 3G & HSDPA are standardized communication protocols. This means that there can be little (no?) device-to-device OR network-to-network variation with regards to the integral working of 3G. The context and application might vary and impact performance, though. For instance if a device is not supplying enough power to its 3G chip, signal acquisition might be slow and strength weak.

I highly doubt the existence of a bug limited to a single network and device brand. By the way the Qualcom chipsets (which incl. the 'radio chip') are not specific to HTC and many companies (incl. Kyocera, Motorola, Sharp, Sanyo, LG and Samsung) feature them. The specific Diamond Qualcomm chipset (MSM720xA) also features in the G1, Xperia, Motorola Atilla & Alexander, LG Incite and MANY others.

I seriously doubt that. To prove this, you would need to test EVERY single 3G phone that has ever existed with the network. Which is, quite frankly, impossible.
Like I mentioned earlier (ct. 1st paragraph) context and application might influence performance. Maybe you're just not in an area with sufficient coverage, maybe your specific device has a design flaw or malfunction. Whatever the problem is, I'm pretty damn sure that it's not "HTC-devices don't work on O2".
I use the german o2 internet pack L and I have the same problem. Seems to be an o2 issue.

That is a much more feasible scenario. Any other O2 users have this problem?
I totally agree with H3x. You say the problem is only HTC devices on O2 so therefore its a device problem. but surely as the problem only exists on O2 its an O2 problem? Every other network in the world seems to be fine. Did you test any other devices with your SIM and network or are you just reading whats on the internet and taking it as true. As we all know, the interwebs is never wrong.
But, your obviously not happy with your diamond so throw it away, go and buy a nokia.

Seems like the HTC-homies in this forum are not willing to read what I wrote before and keep asking the same stuff again and again. I mean, I wrote in the previous linked post all details that you are asking again here...
I'm outta here and will keep at the german forums where people are not constantly trying to convince me that I am stupid...

You're right of course. The bug mentioned here is not limited to a single brand nor a single network. But it seems to be limited to specific Qualcomm chipsets. According to numerous reports in German user boards all (?) devices using MSM7501A (HTC Touch Diamond, Touch Pro), MSM7200A (SE Xperia X1) and MSM7201A (HTC Touch HD) have trouble reconnecting from HSDPA-idle in German O2 network. Doing some research on the web I found similar reports from Swiss Orange users.
From my experience as a German O2 user: An idle HSDPA connection switches back from "H" to "3G" after 25 seconds. If you then send a new request, e.g. tapping a link in your browser, the connection indicator of your device changes to "H" again, but most of the time the connection hang up. You have to manually disconnect and reconnect... Switching off HSDPA/HSUPA gives you a stable 3G connect, however limited to basic 3G speed. Another workaround is to frequently ping around, a 10 to 15 second intervall does the job. With pushmail or some IM messenger active it may work, too.
That's my experience with the SE Xperia. And it's definitely not a local network issue nor temporary - I'm using a Palm Treo pro, too, without any problems at all. AFAIK the Palm also is a HTC device running on a Qualcomm chipset, the MSM7201 without an "A".

IS anyone working on software to use this (or maybe other win mobile 6 pda's) with T-mo's new UMA based system?
For those who dont know what that is, T-mo' is now accepting connections from "compatible phones" via internet (like a vonage softphone), they actually use the sim based data, through the internet rather than through their cellular connection. after paying for the service, all calls originated on a internet connection are not counted against your minutes! They even have the ability to seamlessly (supposedly) migrate from gsm to ip and back again, and if the call orinated on ip and then migrated to gsm, it is not billed against your minutes!
I like my tilt and dont want a new phone, but want to make use of this service to save alot of money on my account! IS there a way to make a "softphone" that will read the data off of the sim chip but use ip rather than the gsm radio? In my research I found that Kineto Software is the company making the software for developers to put into the phones, and a couple of companies over seas (I am in usa) offer similar technology and atleast one other carrier is releasing software for wm6, if I remember reading right last night.
Hey all. Quick question today. I'm taking my first overseas trip this weekend and I'd rather not be without the ever-handy N1. I don't want to run up costs or have to deal with temp phones/sim cards, so I'm going to go with our amazing Dev Team's Wifi Calling method.
I've researched and seemed to have found that even if overseas, WIFI calling will not charge me for roaming if the calls are made back to the US, and I'll confirm that with TMO, but can anyone let me know if they've had success using the process overseas? Is the phone usable once I'm in Asia or Europe if it's still carrier locked to TMO, or will I see some sort of lock out screen?
Thanks for all of your help!
I can't believe that almost a year after the phone is out, some people still don't bother reading before asking...
THERE IS NO SUCH THING AS CARRIER-LOCKED N1 !!!
Now, if you're asking whether the WiFi calling app detects the current network and locks you out in some way - that would completely defeat the purpose of WiFi calling, which is made from places with no reception, so I don't believe it's the case.
haha yeah, no nexus one phones exist that are locked in any way. all sold on planet earth were sold unlocked and carriers just sold them that way.
Good idea using the official wifi calling overseas.
I ignored wifi calling because of the two reasons below, but your idea makes it worth a try.
1) uses your minutes
2) supposedly only for $25 data plan users.
Try to set a proxy (located overseas,working) on your router to test, it may be possible with dd-wrt. Not sure.
The "WiFi calling" application if that is the one you are installing like a phone in a blue speech baloon?
I have used that when out of country before with a Blackberry to avoid those hideous charges while traveling.
That was made for T-Mobile and would not work unless you are a T-Mobile subscriber per my understanding. Not just regular sip client or anything like that.
i have a student plan:
$55 per month
1gb data
400 minutes
unlimited texting
unlimited after 6pm
and
wifi calling - i saw http://forum.xda-developers.com/showthread.php?t=832532
and the vibrant can do that, why cant captivate or can it?
I think you can use google voice to make wifi calls. I think
Fring.
10chars
Fring is not even remotely close to what the OP is describing. Fring/Skype are VoIP based technologies, the Vibrant uses the UMA protocol (and the Nexus S uses SIP technology)... what UMA does is allow you to place calls on wifi as though it were the mobile network (using your minutes too) by connecting to a UMA server hosted by TMobile... AT&T has none of these servers so you couldn't use UMA (might be different if it's unlocked and on TMobile). Add to that it needs a specific kernel module as well as the apk configured to run on the device (Nexus One succeeded in adding this).
AT&T does not utilize the UMA protocol, because they offer the "femtocell" method... go to a local AT&T store and you will see the AT&T microcell which you can buy for your house to improve your signal. The whole point of wifi calling is to improve your reception for voice calls when your home is in a location without strong signal, a femtocell achieves the same thing but instead is just a tiny 3G cell tower that will cover your house and maybe the house next to yours.
So I use minutes to call over wifi...no thanks.
no. wifi calling is calling with your wifi for free, even when you walk out the door and you are out of distance the call will still be free.
I am on rogers, not att

yeah, thats the UMA of old..... TMob is charging your minutes even on the wifi calling on android. blackberry still has real UMA, but its going away
its a service provided by your provider. if your provider doesnt have it and your phone isnt compatible, it isnt happening

as pirateghost said, UMA of old does indeed not use minuets. UMA on android DOES use minutes (at least with Tmobile). Rogers is basically the Canadian version of AT&T, UMA will not work with them. Your best bet is that Rogers either improves coverage in your area or calling and finding out if they support a technology like femtocells. Using Skype/Fring are not the same as they give you a different number, and google voice is (unless I'm mistaken) only free in the US.
