What happened to the 3vo being able to talk and surf at the same time as many reports had stated prior to the release of the 3vo? Is this something to be added later or a never gonna happen type of thing?
Sent from my EVO 3D using XDA App
It works just fine, but only if your data connection is either via wifi or 4G.
Yes I know that same as the EVO but i meant over 3g not 4g or WiFi

Sprint has to enable svdo on their network. The 3d and the EVO shift have the chip set. They are just not activated.

would be better marketing against at&t really, since they are the only one with bragging rights at the moment to be able to do this, not even verizon can at the moment.
Actually the Verizon Thunderbolt can do it currently. Its been something that has been making me think about jumping ship, though at those prices, I should buy a flip phone for when my Evo is online...
The thunderbolt can only do it on LTE and the phone has no toggle to turn LTE off unless its rooted

No the Verizon TB can do it over cdma without being in LTE area. Not all VZ areas support it yet but the phone deff can do it.

Don't think so. the way sprint is doing their voice+data will require a certain chipset on the phones that supports SVDO, which last I checked is NOT in the EVO3D nor the shift. The MDM9600 is the only one ive seen and confirmed to have this built in.
Also a lil note for people that are interested This post lays out some things for the future in sprint and are pretty reliable sources for those that do not know them.

Well people, after reading this thread I just had to put in my 2 cents about it. I live in a 3G area of upstate New York with NO 4G around me and can talk and surf on my Thunderbolt. That was the only reason I dropped the call dropping iPhone with at&t and swithed. I drive a truck "18 wheeler" and everywhere I have gone in the New England area that doesn't have 4G I have been able to do this.

No he's most definitely wrong. The Thunderbolt can do simultaneous voice and data on 3g in svdo enabled areas.
Talk and Surf on EVO and EVO 3D
The solution is not at all elegant and drain the battery pretty quickly.
What else is new here?
In any event, be it in 3G or 4G (irrelevant for 4G I guess):
1) activate the built-in hotspot (password protect it to prevent others taking
advantage of FREE Wifi draining your battery faster than Concord)
2) Activate the phone Wifi and connect to the newly created Wifi in Step 1
At this point, you should be able to talk and surf; an added bonus (already available thru the hotspot feature), is you're able to connect other devices to the Hotspot connection created in Step 1.
The new problem you will have now is to find yourself a lasting battery.

It is only on AT&T. They used to have the commercial about talking and surfing on iphone where the guy forgets his anniversary and makes a reservation while talking with his wife.
Only ATT allows it for the iphone.. but ATT is definitely not the only carrier that allows this like they claimed in their commercials. Probably why you don't see those anymore lol. GET SUED!!!! haha
I've been a verizon customer for a day, came from CSpires mess and haven't looked back. Love my actual 3G speeds and the latest and greatest phones. I don't live in a 4G area but new Orleans and mobile are 1.5 hours away. Excited to see what this thing can do on 4g
Sent from my ADR6425LVW using Tapatalk
The quick answer is yes. The Thunderbolt and Rezound can do voice/data over 3G.
The long answer is no. The Thunderbolt and Rezound technically do data over 3G and voice over 1X on a separate radio.
LTE is a data-only protocol for now and voice is done over either 1X (in HTC's case) or eHRPD (in all other LTE phone's case)

All this was brought up when the Thunderbolt came out and it was proved not to be a world phone.
Ok guys, stop. It is NOT a world phone. It does NOT have a GSM antenna. Wherever you are has a CDMA tower that the phone is roaming to, it has nothing to do with the sim card as it is for the LTE ANTENNA ONLY! Stop getting your hopes up. The LTE OnOff app was built as a universal app, it does NOT detect antenna's. Rezound is NOT a world phone, it does NOT work on GSM.

Both white and black are the same, yes you will get 3G and 4G coverage on at&t since 4G is hspa and at&t supports hspa.
No this phone doesn't have lte and just a heads up, though you will get 4G, it might not be as fast t-mobile from what I've heard, their HSPA isn't that fast but still pretty decent.

I used to work for Business End User Care for AT&T. As of the time I left (november), if you placed your sim in a smartphone and used it for about a day the system would add the lowest data plan and send you a text message indicating it had been added to your account. Even if you were using someone's phone while your "feature phone" wad being replaced, it was required. I've had to read that section of the TOS to many, many angry people. I would call and confirm just to be safe.

DO NOT CALL to ask..... as they won't know the answer, and might put a note on your account to force a data plan(well, you could call and ask on someone else's phone without giving your account number)
the primary way (so far that I've seen) that AT&T detects your smartphone is via IMEI. Secondary might be you using >100GB/month, connecting to their 4G APN settings, going to a store for help and letting the customer rep see that you have a smartphone
does AT&T have your IMEI? probably not.... AT&T has IMEI of all of their smartphones, so you can't use an AT&T smartphone. You can try using an (unlocked) t-mobile phone, but might not support the right 3G/4G bands that AT&T use. You can try international phones, canda phones(from Bell, Telus...). WARNING>>>. AT&T might have your IMEI because the manufacture gave them the IMEI(See Google Nexus phones), inference from branded phones that they carry(eg Phone is sold/branded by AT&T and t-mobile... AT&T gets a list of their phone IMEIs that might include t-mobile's IMEIs), screwups(Samsung Note overseas was misentered as a tablet on AT&T's network, white i9100 Galaxy SII is misentered as a Blackberry on AT&T's network)
The link at the end of this post gives a guide to what phones are 100% compatible(3G/4G on 850/1900) on AT&T's network.
According to this, the T-Mobile Amaze 4G is compatible with AT&T 3G/4G, but I have some confusion on the 850/1900 mhz band for the 3G/4G data, trying to sort it out(last few posts on that thread)
Guide to what phones are 100% compatible with AT&T's network
anyways, quick update
got a T-mobile Amaze 4G to play with

This is not 100%, but just my understanding. The T-mobile version shouldn't have the radio frequencies , or even the same technology (gsm vs. CDMA) as the verizon S4. Dont think there is any amount of software modifications that an allow it either.
No, you cannot use it. It lacks the hardware radio.

Its possible but not probable because VZW is still using CDMA so is Sprint and I do not think the TMo/ATT/GE version have the baseband nor the radios to support CDMA. Once LTE band 4 is enabled and VoLTE is prevalent then the phone can be seemless across carriers.
I know it work the other way around
I put a prepaid att sim card in my ZVW s4 and it worked! As the vzw s4 comes stock as a world phone and can be used on gsm networks. Without unlocking. So if you unlock your TM s4 you should be able to pop in a vzw 4g sim and be OK?
I don't think you will have 4G though if you got a buddy with a vzw 4g phone grab his sim and try it after you unlock.

Again the Tmo/ATT/GE do not support the LTE bands on VZW/SPRINT nor do they support CDMA/EVDO.
The VZW variant should work on any GSM network with a sim swap and APN switch but LTE will be limited or not available.
Right so he won't get 4g/4g lte
But should be OK on 3g after the apn settings are configured I believe. Hope this helps

You CAN, but that does mean you'll want to.
T-Mobile utilizes 2 spectrums for HSPA+ and LTE. 1700/2100 for both. Without access to both spectrums the device will not receive data. Best you'll get is EDGE, which is only from interoperability with AT&T.
There are not interoperability standards for 4G LTE so you couldn't use this on AT&T LTE either.
So yes you can do it, but you won't like the service.

You cannot use the T-Mobile S4 on Verizon, period. It doesn't support CDMA or LTE band 13 which are the only bands that Verizon currently offers service.
Now if you had a Verizon S4 you could use that on T-Mobile since it supports HSPA on the PCS band and LTE on band 4 which are both used by T-Mobile for 3G and 4G but that isn't what the original poster asked about.

With the right hacks...yes. It's possible man.
This article (from QComm) states that the 9615 is capable of CDMA
This link shows very little difference between the 9615 and the 9215...
Again, I implore you all to be diligent when it comes to exploring new ideas...don't just dismiss something as not possible. There's no such thing.
Edit: Just incase the second link to the PDF doesn't work or is REALLY slow...I've attached the document to the post. Also, I took the time to spoon feed someone the info in another post linked here ....
Edit 2: Nevermind, the PDF is 2.5MB...won't let me attach it.
You may want to do a bit more research on the MDM9215. It does NOT support CDMA. It is only used in UMTS/GSM + LTE devices. CDMA support is what differentiates the MDM9615 from its sibling. This was explicitly noted by Qualcomm at UPLINQ 2012 as part of their QCMB API presentation.
So once again I will reiterate that a T-Mobile S4 lacks the necessary hardware to operate on Big Red. Furthermore, it is a simple matter to note that the MDM9215's commercial availability is limited to UMTS/GSM + LTE devices.
No amount of mad hacking skillz can overcome that hardware limitation. It would be necessary to replace the MDM9215 with a MDM9615, which is far from being a simple plug and play operation.

I have the Verizon galaxy S4 running Loki'd Hyperdrive rom and I'm on T-mobile, but I only get 2G (AKA edge and too slow for mms) how can I get T-Mobiles HSPA+?
I was using AT&T's AIRVOICE and got HSPA+ but always got redirected tot he GoPhone account empty screen. so HSPA+ worked but AT&T wasn't fond of my s4 being verizon branded. So I switched to T-Mobile and I HATE Edge. but it's better than nothing.
You can't get a device on Verizon that was not part of the Verizon database to work.
Look at the new Nexus 7, even with the correct frequencies, people are having a hell of a time trying to get a device with the right LTE bands to activate.
If it's not sold as a Verizon device, sell it and buy something else.
