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?

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.

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.

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

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.

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.

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

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.

Hmm I just tested it and it didn't work

. I swear it did work while using the PPC6700....

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."
