Data and Voice at the same time?
 

Hey all,

On my old PPC 6700 CDMA phone I ran HTC Apache (WM 6.1) and there was some registry flag that I set to make data and voice work at the same time. That was a really cool feature. Is there a similar setting for TP2?

Re: Data and Voice at the same time?
 

Bottomline, with CDMA (Sprint & Verizon)? Not going to happen. Network limitation, you can't do 1xRTT (voice & text) and EvDO (data) at the SAME time.

GSM (AT&T & T-Mobile)? Sure why not.

Re: Data and Voice at the same time?
 

Worked fine on Cricket's network - on my PPC 6700. So I don't see why it couldn't work on a TP2. I can't find the old reg hack that I did on the 6700 though. I will add though that when I did this data reverted to 1x, which is fine as long as I could use the Internet and have a call underway at the same time.

Re: Data and Voice at the same time?
 

Give up man like he said earlier it will never work on cdma without a modulation change with the carriers.

Re: Data and Voice at the same time?
 

On my touch pro 2 with uscc, it can use data while on the phone. When making calls / texting it uses the 1x connection (you can literally see it switch from EV to 1x) and it worked the same on my ppc6700. i think its more if your carrier will support it or not.

Re: Data and Voice at the same time?
 

I think you guys are confusing a paused data connection with an active one.

As has been pointed out, CDMA networks can't use 1X (voice and text) and EVDO (3G data) at the same time. It is a limitation of the network.

They can, however, pause the data connection when they switch. So if you have an active download, it stop, and when the call is done, it will pick up where it left off.

You guys that say it works- try watching your slingbox when a call comes in. It can't happen.

This is one of the huge advantages of GSM over CDMA. You can use both at the same time no problem on a GSM network.

If there really is a reg setting to make the data use 1x whilke on the phone, I'd love to have that reg setting. I don't believe it though.

Re: Data and Voice at the same time?
 

There isn't any magically registry settings. I think you can do txt messages while on a call but data is IMPOSSIBLE with CDMA.

Re: Data and Voice at the same time?
 

It was actually a setting that allowed voice calls to interrupt an active EVDO connection. Being one of the first EVDO devices, not all the kinks were quite worked out when it launched. One of the bugs being that voice calls (1x) would simply be ignored if EVDO was active. The entry allowed calls to "ring-through" (pause) an EVDO connection. Search for "ring-through hack" and I bet you find some results.

Re: Data and Voice at the same time?
 

Hmm I just tested it and it didn't work :(. I swear it did work while using the PPC6700....

Re: Data and Voice at the same time?
 

Actually, the technology is coming soon for CDMA devices. The technology will be called SVDO (simultaneous 1X Voice and EV-DO Data) . Do a search for SVDO here on PPCGEEKS. I have a thread about it. But currently CDMA is not capable.

"A complementary device enhancement known as simultaneous 1X Voice and EV-DO Data (SVDO) will also become available during the same timeframe and will enable CDMA2000 devices to access EV-DO packet data services while in an active 1X circuit-switch voice call. For example, users will be able to send emails or access the Web while on voice calls; phones with GPS can update maps or download real-time traffic information while on voice calls, etc. This device enhancement, which enables these concurrent voice and data services, is independent of the air link standard and infrastructure."

Re: Data and Voice at the same time?
 

I'll say this again for the hard heads: It worked perfectly (and still does) on my PPC 6700. The phone drops the EVDO data connect, switches to 1x, and keeps right on truckin' - you can be on a call live and open a browser and surf pages. I've done it. This is on Cricket and I KNOW that it works.

Just wondering what the reg key was for the PPC 6700 so I can try it on the TP2. That's all.

Re: Data and Voice at the same time?
 

What reg or settings hack did you use? Can you post it or a link to it? I wanna try it on Cricket.

Re: Data and Voice at the same time?
 

EVDO spec does not support simultaneous voice and data. EVDV did- but EVDV is dead- abandoned by all the major carriers in favor of lte/wimax. The reasoning behind this is voip. There is no need for separate voice and data signaling. Voip allows for a single stream that supports all functions. Just like you can stream radio, surf the web and send email at the same time. VoIP lets voice just become another application. All that you need to ensure is that the end user device and network can tag and prioritize the voice packets and have a data connection that is low in latency, jitter and has the capacity to support the call. (not much bandwidth is required) 4g is capable of all this.

Sprint's PPC-6700 device allows WiFi and EVDO (data transmission) to be active simultaneously, however if your phone rings (voice transmission), you drop the data transmission. It's one or the other. Some of it is a technology issue. That is, the chipsets used by the cellphones share the same antenna and can only transmit using one of the wireless standards. Other times, it has nothing to do with the technology - the service provider simply decides to block simultaneous voice & data transmission for the sole purpose of protecting their turf. Perfect example - XV6700 Windows Mobile 5.0 phone (Verizon's exact same model as the Sprint PPC-6700) is restricted to only one network at a time. If you turn on WiFi you can't even receive cellular calls. This forces users to stay in "voice" mode the majority of the time, otherwise you can't receive any phone calls.

Re: Data and Voice at the same time?
 

Info appreciated - but this thread isn't about EVDO specs. It's about a reg hack or phone setting hack for data and voice at the same time - what protocol is used when that happens is irrelevant.

Re: Data and Voice at the same time?
 

I think what he is trying to say is that when on a call, the reg hack forced data to go through 1x instead of EVDO, which I guess would make data work at the same time since both use the 1x connection(but would be slow data).

Re: Data and Voice at the same time?
 

op, it's been said quite a few times and you're going to have to accept it: it can't be done anymore. only gsm phones can do it now, cdma can't.

Re: Data and Voice at the same time?
 

LOL - tell that to my PPC 6700 ;-)

Re: Data and Voice at the same time?
 

Finally, someone who understands!

I don't care if it's 1x. I just want to see if I can make it work on my TP2 like it does on my PPC 6700.

Re: Data and Voice at the same time?
 

try it and report back, i need a good laugh! if you want it that bad, pay for the sim unlocker and use gsm.

Re: Data and Voice at the same time?
 

Dude - read the thread. I already said IT WORKS ON CRICKET ON MY PCC 6700.

I don't need GSM. I get massive Cricket coverage where I live, all services included, unlimited everything, anytime, for $45 a month. Why oh why would I pay more for the same thing? I don't want an answer - just saying. Quit hijacking my thread dude man.

Re: Data and Voice at the same time?
 

Pretty sure he's wrong. Just like you can't use dial up internet and use the phone at the same time, you can't use 1X internet and use the phone at the same time.

The reason you can do it on GSM is because the HSPA (3G data) is not what the voice uses. On the contrary- on GSM, if you only have EDGE, you can NOT use data and voice at the same time.

If someone is trying to tell me voice and data work at the same time on Cricket- I need to see a video proving it before I believe it.

Seriously- Sprint and Verizon can't do it, but Cricket can? Not a chance.

Re: Data and Voice at the same time?
 

K - I figured this would turn into a bunch of people saying all kinds of junk about what can't be done instead of someone trying to actually help given the FACTS that I stated. Those facts being:

- I use Cricket
- I have a PPC 6700 (in addition to my TP2)
- The PPC 6700 can handle a voice call and while I talk on the phone I can surf Web pages in IE.

Not sure how it works, or why it works. But it works. So my simple question was does anyone know the hack for the PPC? Because I want to try it on the TP2 over a Cricket network.

I don't wanna hear about Sprint or Verizon or GSM or EVDO specs or what's on sale at your local Walmart.

Sorry if that's sounds a bit curt. I thought my question was pretty clear to begin with.

We need more signal and less noise. Oooo, a cell phone pun.

Re: Data and Voice at the same time?
 

Start a phone call then go to www.whatismyip.com then tell me what your IP is.
This will do two things, prove you can get to a site you haven't been to already (not cached) and and I look at the arin whois info and see if the IP is owned by your telco (not wifi)

Re: Data and Voice at the same time?
 

And I am sorry if this sounds a bit curt, but you are wrong man. You can not use an active data session while using voice on any CDMA network in north america. There are some 3G specs that allowed it, but EVDO is not one of them (and 1X sure as heck isn't either).

Again, post a video proving it. You say all of those claims are facts- not until you prove them buddy. Right now they are just outlandish claims.

The technology Cricket uses (CDMA) does not allow for voice and data at the same time. Period.

I will happily admit that I (and everyone else, on every relevant site on the net) is wrong about this if you post a video. But we all know that won't happen because it simply isn't possible.

So, in short- the "hack" you are asking for does not exist. That's why nobody has given it to you.

You think Verizon would allow AT&T to blast them in all the commercials about voice and data at the same time? I mean, seriously, if it was just a simple reg hack to get it to work? LOL!

It's the technology the network is using that prevents it, not a setting on the phone.

Show me something, anything, that even hints this is possible. The only way it's even almost possible is if the carrier switches to a VOIP instead of a switched network. And even then, it would have to be a pretty high bandwidth and low latency connection. 1X is neither of those. EVDO isn't even good enough to do it (especially the rev 0 EVDO that Cricket uses) let alone a dial up speed 1X connection.

Re: Data and Voice at the same time?
 

Here's my question: what's the purpose of this thread? You have had multiple answers to your question, and now because you didn't hear what you wanted, you're angry? Tell you what, when you figure out how to do it on a CDMA touch pro2, let us know :).

Re: Data and Voice at the same time?
 

OP,

Apparently no one here believes that this can be accomplished. Honestly, neither do I. But where I differ is that I will offer you a solid way to get what you are looking for from your 6700, and have an opportunity to prove everyone here wrong. Do I have your attention yet? Good....

Now request a registry dump from another member here, for a 6700 on Cricket, and then dump your registry. Then you can compare the two on your PC and find the registry addition, edit or deletion that made this work for you on your 6700. When you find it, try the same on your TP2. If that works, post it here in the forums.

I guarantee that if you figure it out and post a working fix, your reputation will grow faster than my blood pressure when watching any movie starring Megan fox.

Re: Data and Voice at the same time?
 

If he posts a working fix that allows simultaneous voice and data on a CDMA Touch Pro 2, you're right, his reputation will be out of control. I'll personally search his history and thank every one of his posts.

By the way, I have an old 6700. If you need a registry dump, let me know. I will probably need some instructions on how to do that too (for free).

Re: Data and Voice at the same time?
 

Well now it's time to add my 10cents!!! This might be able to work cause of this remeber all the sprint and verizon customers that gets stuck in 1x and it has happen to me getting stuck in 1x I can still use the net or any data sevice on my phone so if getting stuck in 1x and I can still browes the web or anything data why can't anyone really try to see if it's possible so don't shoot this down with just hearsay saying that it can't be done lets all really try to make it happen anything's possible remember that they told us we couldn't get "HTC SENSE ON OUR TP2'S AND DIAMOND 2'S" So now lets figure out how is it possible to use data when stuck in 1x when it happends to our phones and it happends! So we can use both at the same time

Ha take dat and dat!:headbang:=D>:mrgreen:

Re: Data and Voice at the same time?
 

1X data works fine. Not sure what that has to do with anything though. But yes, if your phone gets stuck in 1x, you should be able to use 1x data.

You can't use 1x data while you are talking on the phone though. It's either 1 or the other, but not both at the same time.

This isn't hearsay either. This is a well documented limitation of CDMA. It's not a Sprint limitation, or a Verizon limitation, it's a CDMA limitation. And yes, there are some specs that CDMA could evolve to that allow it (EVDV comes to mind) but EVDO Rev A (and EVDO rev 0) flat out can't use voice and data at the same time. And 1x certainly can't either.

Re: Data and Voice at the same time?
 

lol, your asking for someone to make the network do what it isn't designed to do. good luck with that.

Re: Data and Voice at the same time?
 

Ok, guys I am going to try to clear this up for everybody here.
The OP (Marke) is correct when he said he WAS able to use 1x voice and data at the same time with speeds up to 124k. The technology at the time was using EVDV (Evolution Data/voice). The technology DID allow this at the time, however around 2005 carries switched to EVDO.
EV-DV, written in full form as 1xEV-DV, is a 3G voice and data technology for CDMA networks. Providing both high speed uplink and downlink connections, it is none the less unused and has been dropped by its developer, Qualcomm, in favor of EV-DO networks around 2005.
So at the time when Cricket was using the EVDV technology this WAS possible, but again to answer your question is is not possible now with EVDO on your Touch Pro 2 or any other device running on EVDO networks!!!!!!
Case Closed..

Re: Data and Voice at the same time?
 

Re: Data and Voice at the same time?
 

I know what EVDV is (I actually referenced it in an earlier post in this thread). But Cricket never had an EVDV network. They are barely getting EVDO rev 0 rolled out. And the PPC-6700 is not an EVDV device anyway, just EVDO rev 0, not even rev A.

I think the poster is just flat out mistaken. He remembers the tweak that allowed the data to pause when a call came in, he remembers seeing the device switch to 1X, and he confuses that with the data connection remaining active. Also, the PPC-6700 was released in October of 2005, per this link:
http://pdadb.net/index.php?m=specs&i...700_htc_apache
So EVDV was already dead by that point anyway (even though nobody ever used EVDV to begin with).

Re: Data and Voice at the same time?
 

I'm pretty sure this thread was dead before it began. I agree with most posters....not possible on EVDO. Phone and data cannot occur simultaneously. You can talk and text, but you cant talk and mms or talk and surf the net.

Solution: Use wifi and talk :evil4:
You can't change how a network works by doing a registry hack.

Re: Data and Voice at the same time?
 

well i can use wifi and be in a call at the same time. maybe the OP was doing that? also maybe he was hooked up via active sync and was getting the info that way?

Re: Data and Voice at the same time?
 

This thread is like a bad train wreck. I don't want to look, but in fact I keep glancing over to see what has happened now.

Re: Data and Voice at the same time?
 

Sprint users dont like being on hold, are never on hold, have better things to do when on hold, don't browse internet on their cell phones, didn't pay $700 for their phones, don't pay $100 per month for service, can replace battery instead of charging, can load their entire music album on an SD card and lastly, the best one:

Don't have to go OH JOY! when they see the add that you can CUT and PASTE in 2009. haha

Re: Data and Voice at the same time?
 

Ok, PPC 6700; you cannot use DATA and Voice-call at the same time on a CDMA network as its physically impossible on the network. it does not support this.

Your device has been informed :)

Thread closed before this train wreck catches fire.
