[Q] NO HSPA+/Only EDGE on Simple Mobile

So I bought a Samsung Infuse off Craigslist. I love it, it's awesome. I use the Simple Mobile $60/m plan. I previously had a Samsung Galaxy S Vibrant before the Infuse. I used to run CM7 but used Bionix 1.31 as my ROM on my Vibrant. So I'm familiar with the ends and outs of this technology.
The Situation: Samsung Infuse running latest "unofficial build" CM7, flawless performance. After doing much research as to APN settings on Google and XDA I found that the internet is wrong with the APN settings for HSPA+ on a HSPA+ capable phones. I called Simple Mobile yesterday and we did an OTA (she spoke I listened) configuration of the APN and it's full of IP addresses nao. She said that will allow me to access the "4G" network. The thing is, it says "E" for EDGE at the top for my signal....consistently.
The Problem: The EDGE never changes, also according to various speedtest's I can't EVER break .50kbs DL speed off of WiFi.
So I tried switching out various modems that we're available to me for the Infuse via the CWM flashable's. I've seen NO IMPROVEMENT on data speeds after each modem.
So what exactly is the issue: Am I doing something wrong via XDA material? Or am I just ****ed on HSPA+/4G speeds?

Simple mobile use tmobile towers, so u'll never get anything other than EDGE because att&fee phones dont use the same bands

You are right and WRONG all at the same time...fascinating isn't it!
Simple Mobile does in FACT use T-Mobile Towers, however; before I rocked the Infuse I've seen other speeds that read 3G/H. The Simple Mobile Network offers 4G/HSPA+ with the $60/m plan that I am currently on.
So with that information, how would you explain that a phone that is HSPA+ capable and programmed correctly that sits on the EDGE network and still doesn't break .50kbs DL speed??
I spoke with customer service at Simple Mobile and several other Simple Mobile retailers that told me up one wall and down the other that the Samsung Infuse programmed correctly should FLY without WiFi, this phone should act like the rocket it claims to be with data on the network.
Instead it is slow, sux and is worthless without WiFi.
So how come you tell me one thing, and several people that work for the Network and people that are affiliated with it tell me another?

I own a business; I know about selling. But according to my research, your a little or alot off; I just can't exactly prove it.
I know that AT&T offers 4Gish speeds (true LTE in like 2 cities in TX), and that T-Mobile offers 3.5+G-4Gish speeds.
I also understand the concept of up-selling, however that scenario does not apply with my current plan and situation.
Has it, or has it NOT been documented ANYWHERE that an HSPA+ capable phone on the $60/m Simple Mobile plan achieved true or realistic data DL speeds off WiFi?

I am no tech or anywhere educated in this topic. But why are you comparing network speeds with your wifi? Or am I missing something here?

I'm not using WiFi as a comparison, just as another option for higher DL speeds. Off WiFi I've seen snails crawl faster than my data can move.
I just want to know why I can't get anything better than **** with this great phone and supposedly "reasonably-good" network.

They simply dont know wat they r talking about, they r trained within their own company and dont know that other bands exist and not all 4G r on the same band, same for 3G. So i suggest u sell ur phone and get a tmobile phone or switch to ATT. Next time when u buy a phone, insert ur Sim card in and test the network before u pay

The phone was NETWORK LOCKED when I bought it, so I guess I suppose I'm glad you we'rent with my when I bought it lol.
I'll take into mild consideration that a multitude of people may not be aware of alternate existing networks.
The T-Mobile phone I had before licked ****ing sac, my buddy has a Captivate that OVER-SHINED my Vibrant any day of the week - So No, I won't buy a phone from a company that's supposedly being bought out BY AT&T.
From previous quotes: It seems that we are implying that ONLY a T-MOBILE BRAND PHONE can access the 4Gish HSPA+ speeds that Simple Mobile network (that uses T-Mobile towers) and not an AT&T branded phone.
Yes, it's true....the above DOES in fact sound stupid when I put it on paper. AT&T and T-Mobile use the same towers and Simple Mobile/Metro PCS (some other un-explained networks) use the SAME towers.
So how is it, according to posters: That replacing AT&T phone with T-Mobile garbage will allow me to acquire the DL speeds that reference HSPA+/4G speeds. AND NOT, under any circumstances is it possible for an AT&T phone that uses the same towers to get the same outcome?
OK, the last part really does sound stupid, I feel like I'm arguing with a mockingbird. Anyone else have any further to offer?

Actually I re-read this statement. AT&T don't use the same bands, something about T-Mobile uses 850 and AT&T uses 1700.
Would changing the band selection make a difference? How to if possible?

I think u can only change the APN, not the band, the band is hardware, not software. I had the same problem trying to use my Desire HD on tmobile and couldnt get anything more than edge. I did also ask questions here and all i got is the answer i told u. So sell ur phone asap, dont wait until its price drops more

Will straight talk sim work on not "straight talk phones"?
Which cheapest phone of straight talk I have to buy to get their SIM-card?
I know they selling GSM and CDMA phones and don't want to buy wrong one.

Flat Out answer only the 2G or EDGE bands in the phone are compatible with ATT networks the other bands are different so if you want bettter speeds get att or use wi-fi because edge is all you will ever get no matter what you do to the APN

like on the previous post mentioned, i think most of the att phones doesn't have the radio that is capable of receiving the 3g/4g frequencies tmobile use. i could be wrong, but i think is a hardware problem rather than a setting you can change.

Simple mobile is Tmobile, 3g may never work.
Strait talk is a variety of carriers, depends on,the specific phone. The only known phones that work from the att network and have a Sim that works in other phones are the expensive Nokia smart phones. But those also have a Tmobile variant, I don't know how to tell the difference without looking at the Sim.
There is also consumer cellular, apparently that,is att but I don't know if it's full talk text and Web or how it's billed.

Consumer Cellular is VERY "no-frills" - it's only for VERY light users.
There is no AT&T phone that I know of that supports the 1700 MHz band required for T-Mobile 3G.
The only phone I know of that has pentaband HSPA+ (works on both AT&T and T-Mobile) is the Galaxy Nexus.

When I programmed my HTC Evo 3D i saw various optinos for cdma/eg/4g in CDMA Workshop & QPST Service Programming, what I saw was diferent types of bands and freqz, you might wana check out a phone's specs of tmobile and then check if those specs (frqz & bands) match with the one set on your device...
For example
The Vocoder settings
band prefferences :
band class 0/1/2/3/4/5/ sys a/b/
GSM DSC 1800
GSM extended 900
Etc etc.... check with the device's password on it's profiles and realms (settings I can view on my evo using ##data# )

I can confirm that the issue is with the phones. I just ran a test using my simple mobile card on an AT&T Infuse vs Tmobile Vibrant 4G.
AT&T Infuse
Edge connection with 50kps max
Tmobile Vibrant 4G
3G connection with 240kps max
I will be going to staright talk at the end on this billing cycle.

[Q] Is this a known issue? Hotspot slower when talking on phone

Notice when I am talking on the phone while running wifi hotspot, speeds are very slow. Is there a fix? I am using wifi hotspot and not usb tether.

Well I know that LTE doesn't work while on call so i would assume its just going down to h+

Known att issue, they throttle your speeds when on a phone call. Test it out on hspa+.

I'm not sure its even going down to Hspa+ because its just way to slow, nothing loads. I tried speedtest.net and was getting like edge speeds probably even worse.

I remember talking on the phone once and checking the data network type in about phone and it said UMTS (first 3G tech, about 365kbps max). i guess AT&T uses HSPA for voice and UMTS for data while on a call? idk.

Yea you are right, I just checked in About Phone and it goes back and forth between HSDPA and UTMS. That sucks. Would love to browse while talking on the phone. Pages are loading way too slow.

AT&T throttles your phone and also bring it down to UMTS to save battery while in call, if you haven't noticed, it sucks tremendous amounts of battery to talk on the phone and keeping the phone at it's max speeds will just eat the battery dry!

It was found some time ago that AT&T startled throttling speeds during calls.

That would explain why recently I was on a call and I tried to look up something and nothing was coming up on my browser. That's BS. Remember all those old AT&T ads claiming, "Only on OUR network can you talk and browse the web on your iPhone?" I'm tired of being nickle and dimed by these damn guys..

Well it is true, only on AT&T can you talk and browse at the same time on an iPhone. They aren't saying you can browse very well, just that you can. I came from a 9700 Blackberry so UMTS was my day to day and I know the headache.

AT&T: Worst thing about not being able to turn LTE off

I was at the AT&T store playing with the One X yesterday. I had read the complaints about not being able to turn LTE off, mainly centered around battery concerns. Well, I think there is a much bigger concern.
AT&T's LTE network is obviously spotty in most places. It's supposedly pretty robust here in the DC area. Well, the phone I was playing with was constantly switching between LTE and HSPA. And guess what? Every time it switched, it lost its data connection for a good 30+ seconds. So since it was switching back and forth constantly, it would lose data connection for several minutes at a time before it would finally stabilize on either LTE or HSPA for a few minutes. Then it would start switching back and forth again, thereby losing data yet again.
It took me about 10 minutes just to download the SpeedTest app from the market. And then, I could not even get a single speedtest to complete running because it never stabilized on a connection for long enough to complete the test. Web pages wouldn't load. Youtube wouldn't load. Basically rendered the phone useless.
So yeah, battery concerns are there, but they are minor compared to this. If you are in an area with weak LTE, but you do not have the ability to turn LTE off, you might essentially find yourself with no data connection whatsoever as your phone bounces back and forth between LTE and HSPA. I imagine that would be a deal breaker for most people.
I'm keeping my fingers crossed that my house and my office both get either strong enough LTE signals to avoid this, or, alternatively, that they get no LTE signal at all so that it just stays on HSPA.
Battery concerns aside, this is why AT&T needs to give us the option to turn LTE off.

No LTE in my area for a while, which is strange because I live near two big cities and neither of them have LTE yet, for that matter no city in TN has LTE yet

I believe you can technically turn the lte off by selecting "hspa only" in mobile network settings.

From what I've read, you can do this on the Rogers version, but not on the AT&T one.

In the future I can almost guarantee that there will be an option to turn it off and on as you wish. Most likely will require root but, if you aren't going to root it what are you doing here anyways haha

Well for what its worth, A quick flash of a rogers ROM and we are good to go ;-). Not that we should have to, but we shouldn't be kept from doing as we wish with out device. I am sure I will be flashing within the first hour of a released ROM.

Nope they disable it on all their phones. They don't want the customer selecting their network. They can charge more for data on LTE as its faster and you'll use more quickly.
They also don't want us to be able to force EDGE. Totally ridiculous.
I'm referring to the settings under mobile networks

GSM/HSPA ONLY

I might be misremembering an old article, but from what I've read, they're actually starting to repurpose/shut down EDGE towers in cities with a lot of 3G/4G coverage. A good reason to keep us from selecting EDGE only.
I just want them to turn on LTE in Philly.

If the next iPhone (which will have LTE I believe) didn't have a feature where you can disable LTE, then people would go crazy. It's really a shame that the Rogers model allows you to do so but the AT&T model does not. It's not a big deal to me, but certainly I think the consumer should always have that option.

I am one of the lucky ones to still have unlimited on AT&T but there can't be that many of us left where it would affect things.
Pick up an AT&T iPhone 3GS or iPhone 4 and you have an option to turn off 3G. And yes people would go nuts if the next iPhone didn't have an option to turn off LTE.
I hope they don't do away with EDGE. First thing I'd say is, why at home do I get 3 bars of 3G and then if I can switch to EDGE I get a full signal? Call quality isn't broken up like it is on 3G. I'd also like the option to switch my device to EDGE while I'm at work all day to save battery life. EDGE serves a very good purpose for me still.
I think more people need to start calling AT&T technical support and complaining about this. I guess its possible the next update could have this feature.
What good is LTE when its draining my phone sitting in a desk drawer all day?

I remember reading that by "getting rid of EDGE" ATT is actually upgrading those towers to 3G. So, yeah, you lose EDGE, but it gets replaced by better 3G coverage.
Although I entirely agree that not being able to toggle LTE is rediculous.

Just because Verizon rushed out LTE phones before the tech was ready which resulted in terrible battery life, doesn't mean AT&T did the same thing.

Is that even possible? I thought EDGE is still used for voice, and the reason that we can browse and use voice at the same time (like AT&T always advertises). I'm no expert by any means. But I don't think they can get rid of the EDGE towers, until they do something like move completely to 3G for voice, and LTE for all data (which obviously would not happen for a long time).

If spotty LTE coverage indeed proves to be a problem on the One X, you can try manually enter a new APN to force the phone to HSPA+. I read it worked on the Vivid.

Only a solution if you have WiFi access. This would have no impact on the situation the OP is talking about: spotty LTE coverage causing data connection to be dropped.
Also defeats the purpose of having an LTE phone.

Both GSM and UMTS support circuit switched voice calls. Only LTE does not, as there is not yet a standard defined for voice over LTE...so as long as there is a 2G or 3G network for circuit switched fallback, it will work.
Data is independent of voice in all GSM derived networks, unlike CDMA.

Your data connection does not reflect call quality.

At some point when ATT has migrated all of their coverage to LTE capability the network will switch to LTE for voice. Neither ATT or Verizon use LTE for voice calls yet.
Likely within a decade they will turn off their traditional TDMA based GSM voice network altogether and everything will be on their LTE spectrum.

pretty sure they only use gsm for calls, as people without data plans that have smartphones (dont know why they do that ) still make calls and text, just cant access teh interwebz

No you didn't get it. Even without LTE they slow down any connection when on a phone call to save bandwidth. You can be getting 6 mbps down and then make a phone call and barely hit one and the upload is like 0.00mbps.
Test it out. Immsuremit will be like that once LTE is voice enabled.

The current deployments of LTE are based on the LTE Release 8 with LTE used for data and 3GPP/3GPP2 (i.e. GSM/UMTS/CDMA/EVDO) for voice.
This will all change when the carriers move to the VoLTE (Voice over LTE), which is most likely a few years away.

Yes, from what I understand, there is no standard yet for Voice over LTE, the various stakeholders are still working this out, and its still a long ways away.
So for the present time (and near future), LTE is data only (and no voice) on all carriers.

I wasn't agreeing or disagreeing. I was stating something entirely different from the OP.
Its not widely known that AT&T throttles all data speeds during calls and I was being sarcastic by adding that once you can do LTE over voice, they'll throttle that too during calls only.
Run a speedtest next time your on the phone and you'll see. Doesn't matter what data plan you have, they throttle all data speeds during calls.

Agreed, I told At&t that i wanted to cancel my service because Im paying for hotspot and its shif during calls. I was never told this before signing up for service. Im upset because hspa+ is enough for my needs and will work during calls but they had to go and throttle the service!

The standard is pretty clear.
You have 3 options for voice under LTE (as of Rel8):
VoLTE - IMS VoIP using AMR
CS (circuit switched) Fallback - basically have the phone camp in the LTE network, and fallback to 3GPP/3GPP2 only in the case of voice calls
SVLTE (Simultaneous Voice and LTE) - the scenario I already described and launched with most NA carriers
The reason for the delay in VoLTE deployment is the difficulty (and cost) in implementation. VZW, AT&T, etc. would probably want to recoup investments in the 3G network already in place before they spend more for VoLTE. At some point in the future, recovering air spectrum from the 3G band is going to be a higher priority than re-using the deployed 3G network, and that's when we'll see more VoLTE movement.

[Q] From sprint to AT&T..a little confused.

This Q&A has more to do with the carriers as opposed to the phone. I was with sprint for atleast 8-9 yrs. They recently cancelled my account because of excessive roaming data usage i believe. I miss sprint (unlimited data plans), anyway. I just got the HTC One x and its a great phone, but its not like my previous Evo. Some of the settings I've come to use are gone. Like, does it suppose to be an option to turn the 4g signal off like on the evo or is it just "always on". I dont see any settings for that. Regardless its not an issue since the battery like on the HOX last longer than my evo, but I was just wondering
Another question concerning roaming. Does AT&T allow roaming(stupid question)? My parents stay in the boondocks, and when I visit them, there are times when my phone completely says "No service" I've never seen this before with sprint because the phone would just connect to the Verizon tower(s) nearby. Does at&t allow this? I read in the contract about excessive roaming..but I get great service at my house, just none at theirs. (sprint on the other hand roamed at both places. hence the termination)
Just a couple of carrier related questions i guess because I've only used sprint for the entire span of my cellphone usage, and this is my first time going with a different carrier.

You can't turn LTE off as far as I know, but I think you can turn "4G" somewhere in the setting which will put you on Edge though. Only roaming you need to worry about is if you're leaving the country.

Same as above, you wont be charged for roaming unless going outside of the US. But at&t phones don't roam internationally unless you enable them to through settings, also at&t is a little bit forgiving with roaming I was in US soil in a place with good signal, but my phone decided it wanted to roam an Canada 3g since the area I was in didn't have 3g I ran up $700 bucks in data, it was like two Facebook statuses, lol. But they refunded me since I had agreed to an international data block.

I too just switched from Sprint and an Evo to AT&T and a HOX. My experience has been different, though. I have family in the sticks and Sprint would always cut out. With AT&T I get consistent coverage and with HSPA+ I am getting data speeds 5x what I got before.
But I too wish I could turn off LTE since there's none here. When the kernel source is released this should become available though on custom roms.

ok i understand now about the 4g..but if at&t allows roaming, why did my phone show "no service" is there an option i need to untick/tick to enable it. Im pretty sure i clicked "data roaming" under network settings.

When I was on the Nitro, *#*#4636#*#* gets you to where you can click "Phone Information" and towards the bottom you can change the network type. From what I remember it does not persist past reboots.
However, when I try it on the AT&T HOX, I can't get the setting to stick, it just immediately switches back to LTE, so there may not be a way for us to set the phone to HSPA+...

Because there are no other gsm carriers towers to borrow from either I'd assume.

Yeah, Verizon/Sprint/US Cellular use CDMA. AT&T uses GSM. incompatible technologies so you can't roam, you'll just have no service
