i have a few question. i just bought my sensation. i would like to know if tmobile is going to charge extra for 4g usage conserding im using a 3g sim card. i read somewhere that 4g phones have different plans.
2nd is tethering free on the sensation and if not is there a way to make free (rooting or something)
3rd is there a way to disable 4g to improve battery

You should be able to stick with your current plan. That's what they did for me, and many other posters.
Are you actually seeing a 3G icon? What UL/DL speeds are you getting?
There's currently no way to disable 4G and force 3G. You can disable WCDMA, but that will force 2G only.
Tmobile's 4G is actually just 3G plus great marketing. You can disable 3G to help your battery but then you'd be down to just EDGE.
I am getting 4g service I was just wondering wether there was a 4g sim cand or something that would improve the spewed cause honestly its only a little faster. Also for some reason my Yahoo mail won't sync any sugggestions. And btw I'm loving this phoon coming from the hd7

So, to clarify, are you saying there's no protocol difference between TMO's 3G and "4G"? Is the TMO 4G just an upgrade in speed of the same 3G data connection? Since it seems there are 4G SIMs, and the IMEI needs to be registered as 4G, and the phone needs special HW and SW for 4G, I was under the impression that TMO's 4G is actually a different protocol.
I understand TMO's 4G does not meet the speed definition of true 4G, but it could still be using a separate data format and protocol than 3G.
On my phone so I really can't provide all the links and stuff but tmobile's
4G is hspa+ which is 3G tech. You can research more about it if you want.

Because it does?
I guess I'm confused. Do you have a problem with using a SIM card? They actually are a pretty darned good idea in my opinion. Especially if you want to travel overseas with your phone, and buy a local card at the Quickie-Mart.
Found this from a quick Google search.

The OP is wondering WHY it needs a sim card. Stop being such a smart ass.
No I don't have a problem with using a SIM, I was with TMobile for a while and know how useful it is, as a matter of fact when I was in the Navy we had a sim imbedded into our smart card IDs. I appreciate the link, does this also make it a world phone or will is it only used for LTE?
No, this is not a world phone. The SIM is just a spec that is required for LTE
10-4 thanks fellas

While the Charge (or, any other LTE phone) isn't technically a "world phone", it can be if the country you go to supports LTE - at least partially.
The Charge doesn't support VoLTE (Voice over LTE), which requires a special modem chipset. I believe the Revolution does have the VoLTE chipset. If you have an LTE phone with VoLTE, your phone will eventually be a "World Phone" when other countries implement VoLTE.
That said, you may be able to use your LTE phone in an LTE country to make calls using a VoIP application, such SIPDroid.
On the bright side if you switch between 4g phones, you can just plug in your sim card like a GSM phone.
That's what I do to switch between my Tbolt and Charge, none of that x228 stuff. Just plug in my sim and all is well

That's IF the country you are in is using the same LTE bands as the US. Think about it, how many GSM bands does a phone need to support to work for Voice and Data in every country?
GSM and CDMA are forks of the same technology.
Way back when things split, the CDMA-based carriers (at the time AirTouch, and Sprint) decided that (partially in order to keep carrier lock-in) it would be better to include everything needed for connection to the network within the body of the phone. Essentially, CDMA phones have the SIM integrated into the SOC.
In comes LTE, which Verizon decided on as their 3.9G technology, but also happens to be SIM-based and doesn't support the integration with the SOC like CDMA.
If you look closely, the primary technology behind GSM networks is actually called WCDMA.
LTE must dictate that the SIM be removable then because it could easily be integrated. Otherwise 4G looks like an afterthought.
here it is... lets get rollin!

Nope. CDMA cannot run both data and voice at the same time. HSPA can, but CDMA cannot. This is a technology difference at the carrier level and software can't fix it.
(This is why the iPhone or Android on Verizon cannot do it either - but I believe LTE addresses this, so as carriers migrate that way...)

Verizon started introducing simultaneous data/voice on the Thunderbolt, even with 3G CDMA. It is possible, but the carrier (and phone chipset) has to support it. The technology is called SVDO. It enables EV-DO data while the phone is on a 1X call.
Found a write-up about it here.
Yes! I can't wait for a ROM too. I really hope the gps sync issue is fixed along with a new rom. It's not essential for me, but it would make this phone more likable than the Optimus V if someone will make a rom that fixes a lot of the issues this phone has.

Just to expound on this, the idea here is just a bit more complicated on simultaneous voice and data (you're exactly right and I dont mean to offend at all, I'm just adding to your point).
SVDO as you mentioned, and LTE, are two different things in the idea of simultaneous voice and data. SVDO, as you already said, allows a 1x and EVDO session to occur simultaneously, and requires the chipset to support it. The problem is that very very few actually do. The thunderbolt is one such phone, but it only does it in very specific circumstances and in a special way.
LTE is an IP-based technology, and therefore treats voice and data the same (like GSM).
That being said, VoLTE (Voice over LTE) is not an easy road because of the difference between 3G and 1x (circuit switched networks), vs. LTE networks (IP based). Because of these huge differences, bridging equipment must be used to work with the handoffs of calls between the networks. This process on phones is called eHPRD and is in place on all current Verizon 4G phones. This process will not actually be used though and is an empty feature. This process is so complex that Verizon has said that their VoLTE system will NOT be doing handoffs to 3G or 1x. Calls placed and received on 4G LTE networks must remain on the network. That is why for now, Verizon's LTE ONLY handles data, Verizon is not initiating VoLTE until the first half of next year.
Also keep in mind that while LTE + 1x voice is *technically* simultaneous voice and data, it is not SVDO in the sense of the acronym, which refers to sending voice and data over the same bands by using spare frequency from a 3G data session to "squeeze in" a 1x voice band in the space where previously, a entire 3G band would have been placed. LTE + 1x voice is really no different from using Wifi + 1x voice. Both rely on the idea of using 2 entirely separate bands for a voice and data session rather than squeezing a voice and data session into 1 band.
The thunderbolt can do SVDO because it has 2 radios (and a proper radio firmware to enable SVDO and allow the two radios to work as 1). The qualcomm processor + radio (MSM8655) gives the phone its 1Ghz processor and the capability of 3G and 1x (but only 1x is used on the Thunderbolt); and then a second qualcomm radio (MDM9600 Gobi Radio commonly used on 4G mobile broadband cards) capable of LTE and 3G. That's why it has antennas literally bursting at the seams (and into the battery cover), and why its battery life is amongst the worst of all the 4G phones. A call received on the Thunderbolt always goes to the 1x radio on the MSM8655 processor. 3G and 1x treat data and voice separately, with 1x capable of voice or data and 3G capable of simultaneous voice and data only if SVDO is supported on the chipset (the thunderbolt nor any other 4G verizon phone support SVDO on a single chipset, the thunderbolt is able to do it with multiple chipsets). I'd make a table, but I'm not really sure how to, so in case my rambling on was a bit confusing, I'm going to lay out a concise list assuming Wifi isn't being used (which as said above is similar to LTE + Voice on current networks) That will change next year.
Verizon Thunderbolt:
When in a 4G LTE zone:
Data is sent over the 4G LTE radio from the MDM9600, while received or placed calls to the phone go over the built-in 1x radio in the MSM8655.
When only 3G is available:
SVDO is activated through software. Data is sent over the 3G radio from the MDM9600, while received or placed calls to the phone go over the built-in 1x radio in the MSM8655. The 1x band for the call is squeezed into the same band as the 3G data session using SVDO.
When only 1x is available:
Only the MSM8655 processor has a 1x band, so the session can be either data or voice, but not both. Even if the MDM9600 had 1x, it would not be possible to have simultaneous 1x voice and data because it is impossible to squeeze a 1x band into another 1x band.
Droid Charge, LG Revolution, and other current Verizon 4G phones: The phones all share the fact that their 4G radio only supports 4G, there is no 3G or 1x data band in the second radio like the MDM9600 used in the Thunderbolt.
In the case of the LG Revolution, the same MSM8655 used in the Thunderbolt gives the phone its processor, and in this case, its 3G and 1x bands (The 3G is enabled on the MSM8655 on the Revolution but not on the Thunderbolt). This is because its second radio, the LG L2000, is only capable of 4G LTE.
In the case of the Droid Charge, the Hummingbird processor used does not have a built in radio. While the Thunderbolt and LG Revolution use a (Processor + Radio) + Radio methodology, the Samsung Droid Charge uses a Processor + Radio + Radio method. The Droid Charge has a VIA CBP7.1 radio to handle 3G and 1x, as well as Samsung's own CMC220 radio that once again, is only capable of 4G.
This results in the Revolution and the Charge behaving the exact same way:
When in a 4G LTE zone:
The phone's 4G radio handles data, while the phones primary radio handles voice.
When only 3G is available:
On both phones, the 3G / 1x radios do not support SVDO. Therefore, the phone can support a single 3G data session until a call is placed, in which case the phone drops to 1x voice, removing data access while in the call.
When only 1x is available:
Same as when only 3G is available, except the phone is holding a 1x data session until a call is placed, in which case it becomes a 1x voice session, removing data access while in the call.
As for current 3G phones, no singular chipset fully supports SVDO, and since almost all phones only have one 3G/1x radio, simultaneous voice and data on these phones is impossible.
SVDO requires the carrier to support the technology, as well as the chipset in the phone to support it and the software to enable it. So far, no individual chipset supports SVDO. This includes the MSM8655, otherwise the LG Revolution would support SVDO over the 3G/1x bands built into the processor. But it does not. This first gen hardware is hacked together as 3G phones with additional 4G radios. This allows the Thunderbolt to get SVDO simply because its 4G radio also supports 3G. Since the software is written to allow SVDO, the two radios work together to provide it.
Late next year I would expect to start seeing matured single-chip solutions containing 4G + 3G / 1x in a single chip. These chips should allow built-in SVDO + VoLTE. Until then, there's not much support for it in current hardware without a multi-chip solution.
Lastly, I'm sorry for the long, drawn out, entirely off-topic post. But I hope it clears up some thoughts as to where we are headed with current CDMA technology and the transition to LTE.
Does the incredible 2 have the right hardware to support svdo?
Hello everyone,
Just got my Nexus 5 with carrier AT&T and got my LTE activated using the IMEI that came with the N5 and everything works great. Just a quick question regarding the icons that are shown depending on which network you are on. When on LTE it will show LTE above the signal bar. When not on an LTE band it will switch over to H. My understanding is that the H stands for HSPA+. Would this be the equivalent of 4G? I was under the assumption that the H was basically 3G. I also thought then when using LTE it is considered LTE/4G, so wouldn't the LTE switch to a 4G symbol, or does the Nexus 5 not have this and that would be what the H is referencing.
Thank you.
H is hspa+ which is faster than 3g but not as fast as lte. I am usually on H+ or lte. I rarely get the 3g symbol on AT&T. I also found that H+ is almost as fast as Verizon LTE. I think it is due to do many devices on their network.

Thanks, so basically you won't get the 4G symbol on the Nexus 5 using AT&T? Mainly what happens is i'm on LTE, then when I make a phone call it switches to H (HSPA+). I thought AT&T is able to do voice calls over a 4G network. I may be wrong.

You may have to manually add in AT&T's LTE apn (which you can find with a quick google search) if your phone doesn't automatically pick it up. Also make sure your SIM card has been provisioned to work with the LTE bands (use with another 4G phone ex. S3, HTC One)

Well I get LTE, I just don't get 4G. I figured the phone doesn't show a 4G icon, but if it does, then I'll check my sim in another device.
Google just changed the "4G" icon to "LTE". On jelly bean, LTE would show "4G" if you had the hybrid N4 radio flashed. hspa+ has always shown "H" on the stock ROM. Some custom ROMs have you the "H+" symbol though.
As for voice calls on at&t, they go over their hspa+ network, at&t uses their LTE for data only at this time. BTW, at&t considers their hspa+ to be "4G".

4G and LTE are the same thing. LTE is a denotation of the network standard just like 3G is EDGE. If you're getting LTE above the signal indicator you are on the 4G network.

Yeah, it is the same on T-Mobile. When they refer to 4G, they are referring to HSPA+ (or H). I like to call AT&T and T-Mobile's 4G, fauxG since it is really just an improvement upon 3G. I don't know who shot first, but I wish the marketing teams would have called it 3G+ or something instead of lying to everyone or at least referred to LTE as 5G. So now everyone has 4G and 4G LTE and really LTE deserves more as it isn't a hack job to get more speed. It will replace all the legacy networks and even eventually be used for voice transmission.
Yes it switches because they're currently you cannot surf the web while being on a phone call with LTE, so it auto switches to hspa+ so you can surf the web while talking

I'm with Australian network provider Telstra, and my phone shows 4G all the time(regardless whether it is transmitting data or not) when I'm in 4G coverage, 3G when I'm not in coverage and not having data acativity and H when it is transmitting data. Do you think it is the different device model and/or the network provider contributed to the difference between mine and what you guys have in the State?

This confuses me. Can't the nexus 5 use both at the same time? You're getting text messages over HSPA(+) with LTE on.
I'm still puzzled why when I make a call why LTE goes away and HSPA+ shows up. This is on T-Mobile.

Well, I have some good news to report. I was having the same issue as you and really getting down about it. I went to my nearest T-Mobile store and told them of my situation. The rep called tech support and he did some sort of reset to my account, I am not sure what exactly. I also asked if I could get a new SIM. I was given that new ISIS SIM and as soon as my phone fired up, it started using LTE. After I left the store, from being in my pocket, it was on HSPA for a few moments and then it finally chose LTE and stuck with LTE the entire time I was within its coverage. I am really happy with my phone now, it now behaves like my hacked Nexus 4 on LTE did.

This isn't *entirely* true.
You'll see the LTE symbol when you're on LTE, that's easy.
You'll see the H when you're on HSPA or HSPA+, which means you'll see it when you're on the network that old phones used to just call 3G.
The other symbols are specifically for Edge. I know it doesn't seem like it, since one is a 3G symbol, but do a speedtest and you'll see it. Modern phones display things poorly for connections because of the differentiation of HSPA and HSPA+. It's obnoxious.

ITU-R said:
On December 6, 2010, ITU-R recognized that these two technologies, as well as other beyond-3G technologies that do not fulfill the IMT-Advanced requirements, could nevertheless be considered "4G", provided they represent forerunners to IMT-Advanced compliant versions and "a substantial level of improvement in performance and capabilities with respect to the initial third generation systems now deployed".

LTE, and even HSPA+, are considered 4G.
As for the 'Why does it switch from LTE to HSPA+ when I make a call?' question, LTE does not support standard switch-based telephony, meaning you cannot make voice calls using the network. Some carriers (I think Verizon is ahead, but I don't remember) are going to be supporting VoIP soon (voice over IP), which allows calls to be made using the LTE network, but they're all data-based (think Skype). As such, current phones will switch to HSPA+ or CDMA to make the phone call and then switch back once it's done.

That's not really accurate. Verizon's newer phones (Galaxy S3 for example) will let you call while on LTE. That's why I'm having such a hard time understanding why the N5 won't let LTE stay on while making a call. Doesn't it have a radio for data (LTE) and and radio for voice? Seems like both should be working in parallel like on VZ.
I remember reading about phones like Moto X (2014) and Droid Turbo not being able to use simultaneous voice and data unless they're in a VoLTE area since they don't have separate antennas like the Note 4 and many others others do.
Will Samsung Galaxy S6 have simultaneous voice and data no matter if it's in a VoLTE or 3G area?
Of course it will.Only on 3G or LTE (LTE switches back to 3G when a call is initiated), but it will.

So it'll have two separate antennas then like the Note 4?

I have no idea how it is done technically, but I do not imagine a high-end phone not allowing voice and data at the same time, unless it is called an iPhone, of course.
I mentioned Moto X (2014) and Droid Turbo in the OP. Those are both high end phones.
I also remember reading that having one antenna is what most manufactures will be going for in the near future when I was researching the Droid Turbo.
no phone will have two antennas anymore (i doubt anyway) because carriers are now moving towards Voice over LTE, so unless you're in a VoLTE area, no.

I'm going to still have my fingers crossed that we'll have two antennas in the S6 since the Note 4, which is a relatively recent phone from Samsung, had them incorporated.
Of course, if you're 100% sure (and perhaps have some type of proof?) that the S6 will only have one antenna and not be capable of simultaneous voice and data in a non-4G LTE area then I will take your word for it and be a sad puppy.

well it more or less depends on the carrier too. verizion seems to retain dual antennas on their phones, where as sprint on the other hand, not so much. the note 4 for example has dual radios, but iirc you can't use both on sprint at the same time, at least not until they fully enable volte.
the Note Edge came out at the same time as the Note 4 and iirc, it does not have dual antennas, so who knows..

That's the thing. Verizon's Moto X (2014) and Droid Turbo both have only one antenna... BUT as already discussed the Note 4 had retained dual antennas so I'm hopeful that Samsung did the same with the S6.
Unlikely that S6 can do SVLTE because the FCC test docs say as much and because VZW is moving toward VoLTE the need is not there. 5.1 Android has the VoLTE switch built in.
With GSM providers its a little different for example ATT will drop you to HSPA+ during a call to support Data/Voice if a call came to your phone.
Its a loss, yes, but for the OEMs it reduces cost and perhaps saves some battery life.
my 2 cents

Correct, no SVLTE. Says so right on the docs.
Definitely a shame, but that is the trend for CDMA carriers these days. HTC m9 is the same way.
Correct.
For example on my factory unlocked Galaxy Alpha 850M which is on Metro PCS/Tmobile
and has ALL the 3G and LTE Bands for Tmo - the phone says LTE in the Display but as soon as I make a call it drops to 3G H or H+ AND I do have simultaneous Voice and Data 98% of the time but NOT VoLTE.
Metro and Tmo Branded phones have VoLTE so you always have voice and data AND you have voice and LTE Data Simultaneously- this is Software enabled by or for the specific Carrier.
The one handicap of a factory unlocked phone no one ever mentions.....
Has anyone figured out how to get rid of that notification for when you can't use your data while talking on the phone? This happens always when I'm driving and using navigation (waze) and it's pretty annoying.

I am having a problem with my USCC S6 with this. They do not have voLTE yet. I was able to use data during calls with my S4 & S5 but I can't with the S6.
Any news on getting data and calls to work simultaneous? Very disappointed that this happen coming from the s4.. Is it physically impossible because of the hardware? I'm just starting my search on this issue so bare with me..
