Is there a way to actually boost antenna strength? - Sprint Samsung Galaxy S III

Since it seems so obvious now that the 800 and 850 band radio is so terrible, I'm wondering if there is any way to physically enhance the reception abilities of the antenna.
I ask now because this has become a safety issue for me when I travel throughout the state. I don't even really care about having data while roaming but I really would like to have some sort of dialing capabilities.

Idk it could be possible. If you open up your phone, your antenna snaps on and off like all your comments inside. It runs up one side of your phone. You could search through eBay and see if there's any stronger aftermarket antennas to replace with. But ya, do some research first and see what people say about the antenna if you find a different one

What do you mean since it seems obvious now that the 800 and 850 band radio is so terrible?
Last i checked Sprint was not using the 800mhz stuff yet as IDEN is still up and using it. Sprint is still using 1900mhz pcs band.
FYI, its not 800 and 850, those are the same thing. the 800 band is actually in the 850mhz range.. so when someone says 800 they are refering to the 850 as well. So its 1 band not 2.. But if im wrong let me know.

You are correct. However, when roaming, our phones use the 850mhz cellular band if there is no PCS signal available.
For some reason, reception in the 850mHz band is noticeably inferior to any other Sprint phone I've ever owned. My S2 gets a great signal where the S3 has no service.

How are u concluding that it's the antenna that's the culprit? With all the construction and destruction sprint is doing to their network at the current time(IDEN being phased out, LTE rolling out, 3g and voice upgrades to current towers, and EHRPD thrown in the mix), it very well could be a network problem not the phone... I would suggest doing a bit more R&D before diving into a project like this. If u have the free time and just wanna do it by all means go for it. I would make sure u have some way of getting a replacement if something were to go wrong. I personally don't have any problems when roaming with voice quality...

I highly doubt you will find a better antennae for the phone but what i know you can find is a signal booster for your vehicle from a company called wilson. Google it.

I base my conclusion on the antenna because both my ZTE tablet and my Epic Touch both get good reception in Crivitz, WI, when my S3 shows no service.

Have you tried a different modern/baseband? Updated profile and prl?
I have no issues with service compared to their coverage maps.

Im leaning towards different PRL. Going out on a limb here.
Tablets use a different PRL because data roaming agreements are different then voice.
GS2 uses a different PRL as well due to WiMax and its an older device.
Or as Speedin07si mentioned different modem/baseband.
Also when doing reception testing using different devices really isnt a fair comparison. To know if your device has an issue you need to throw an identical model device into the mix for a real comparison.
I still dont believe the implemintation of the 800 band for CDMA has been deployed yet and as a result dont think that is the issue.
But i have, in the past, with other Samsung devices had issues with modem/baseband and with my old Epic and Epic Touch sometimes found i had to play around with different modems to get best performance.

That was my thought, as well. I tried the signal comparison on all three devices (all three are rooted) with prl 11115. The ZTE and the Epic Touch both had fair to good reception (the tablet had a 3g connection while the Epic Touch had 3g and 4 bars of voice reception). The S3 wavered between reception with 0 bars (connected, but not enough to get a call through) and no service.
In areas with native Sprint coverage, the reception in the S3 is much better than the other two devices.

Sprint converts its CDMA network to LTE, to be completed by 2013

Sprint converts its CDMA network to LTE, plans 'aggressive rollout' to be completed by 2013

We knew more or less that anannouncement of this sort*was coming. Back in July,*Dan Hesse had teased usface-to-face with the promise of a "great story this fall around 4G," and now the time to tell that tale has arrived. At its strategy event today, Sprint finally went public with plans to "simplify its network" by converting its CDMA 1900MHz holdings and LightSquared's 1600MHZ spectrum ("pending FCC approval") to LTE, anindustry favorite. Helping the operator make that transition is the swath of 800MHz spectrum it reclaimed from the, now defunct,*iDEN push-to-talk network*-- which had been a drain on the company's resources. This spectrum, acquired from Nextel, will be phased out by mid-2013 and rolled into LTE. The company plans for a rapid deployment of this new 4G, with the first LTE markets and handsets to hit in mid-2012 with the full rollout mostly completed by 2013. Current subscribers signed up for WiMAX plans won't have to worry as their devices will continue to be supported throughout 2012.Beginning tomorrow, Sprint's consolidating its 4G LTE (including LightSquared), 3G and Direct Connect networks into one single architecture. All the major technical milestones, such as test calls and field integration, have cleared their hurdles and work on over 22,000 cell sites are currently in process. Samsung, Alcatel Lucent and Ericsson have partnered with Sprint to install multimode 3G and 4G base stations to handle the network's future traffic, essential for deploying the multitude of frequencies required by hosted devices. Prospective iPhone 4S users on the network will be able to take advantage of better signal strength and improved voice service as Sprint intends to also offload the latter onto 800MHz.Expect a steep "reduction in roaming costs" and deeper signal penetration throughout the operator's expanding national footprint over the course of the next two years. Naturally, LTE speeds on this new network will be significantly improved over the currently in-use WiMAX, and a planned implementation of WiFi offloading should help to cut congestion by 20 percent. By the end of next year, Sprint aims to have a combined WiMAX/LTE population coverage of 176 million -- with 123 million covered by LTE and 76 million overlapping both. When the network build-out is nearly complete in 2013, the company should have over 250 million blanketed in LTE, far outstripping the stagnant 120 million served by WiMAX.

I really don't think Engadget and BGR are getting this right! It's not being converted to LTE - the LTE will be everywhere that 3G is, but its multimode architecture doesn't mean 3G is being replaced! They said they are "committed" to the 3G services long-term, and will be maintaining them. They pointed out how the enterprise customer is important, and demands at least 3-5 year stability.

LTE is only, at this point, a speculation on 800mhz. 1900mhz is first, then 1600mhz via LightSquared.

See now I don't know what to do. I was considering the ET4G or the Nexus Prime if it gets announced soon. But I'm wondering If I should stick with my OG EVO until LTE starts to roll out and see what phone comes then? My 3G blows along with 4G only getting like 2.5 down and I'm in Kansas City, right down the road from the Sprint Headquarters. I'm pretty disappointed in these speeds.

Sprint made it clear that LTE won't be of much use until late 2012, but they will be selling WiMAX phones through 2012 and supporting WiMAX for much longer. Also, watch for speed increases as they continue to increase backhaul as part of Network Vision.
What's most exciting about all this is the transition from EVDO to 1x advanced

3G speeds having nothing to do with the antenna bars you see on your phone. It would make sense that if you have a strong cell signal, you should also have a strong data signal, but welcome to Sprint!

GSM Nexus speed on AT&T (Austin, TX)

I don't know if this is a question or more of a poll...
I think I'm getting horrible 3G speeds here in Austin, TX. It also seems like I'm being capped. When I have full bars, speedtest always shows around a 3Mbps down and 1 Mbps up transfer speeds. I've tested this in many places around North Austin / Round Rock.
What speeds are others getting?
Could my sim card or data plan need tweaking from AT&T? I ask this because I was previously on a Galaxy Note with LTE and they had to switch me to a LTE plan at the time. Outside where I work, the LTE signal strength is very strong and I've gotten amazing speeds with the Note. But with the Nexus, I get the 3/1 speeds.
Any ideas?
What are your APN settings, also are you on the smartphone or medianet plan?

Thank you for helping me.
I'm on a smartphone plan. Which APN settings are you wanting? There are a lot!
I live in Bastrop, like 30 miles east of Austin, and am getting about 2.5-3 down and .4-1.2 up. I was pretty disappointed because I thought I had remembered pulling more on my Captivate(smart phone plan though), too bad it broke. I'm using the MediaNet plan on ATT with AndroidHD Revolution(4.1.1) and Franco r223.

If you're on the smartphone plan, I'm assuming you're using the "phone" apn? Also, you're aware that you can get unlimited hspa with the non smartphone plan formerly known as media net.
Who knows this could be purely speculation but let's say AT&T already has your imei number you could be automatically bumped to the same smartphone data plan if you attempt to use the dumb phone plan.
I am unsure how quick AT&T is figuring this stuff out. I had an AT&T GS2 and switched to a dumb flip phone then bought a GNex, took the sim card out of the dumb one and transplanted into the GNex and boom, unlimited data and texting for $30 a month.
I'm already on an unlimited smartphone plan. I chatted with AT&T support and there are currently no restrictions on my data plan. He also switch IMEI from the Note to the Nexus and moved me from a LTE plan to 3G plan. Data speeds remain the same.
I wonder if anyone with a GSM Nexus in Austin is able to get > 3Mbps...
Try the phone apn?

You are on a SGS2 with HSPA+? Which city are you in?
Try testing with actual downloads instead of speed test sites. My speed test (I'm in northern Colorado) always tells me about 3Mb/s down 1Mb/s up too, but on actual downloads and manual tests, I hit 8-10 Mb/s even in kind of rural areas.
I'm in Indiana and get around 3-4mbit down and 1-1.5mbit up. The fastest ive seen once is 7mbit down.

I remember with the captivate, the speeds would vary widely depending on which part of town I was in. But with the Nexus, it just seems very artificial to hit right around 3 down / 1 up every time. Almost like AT&T is capping it similar to what they did to the captivate. The modem AT&T put on the captivate was throttled for whatever reason but flashing an international modem removed it.

ATT uses QoS to determine which devices on their network receive priority as well. Iphones receive the most for cell phones of course.

Yeah. I had to send my Gnex in for service. Only got to use it for 17 days
Harbor Springs Michigan
Sorry to bring back an old thread, but I am wondering on this myself. I bought my gnex from google play, got it and noticed that the data rates are pretty steady at around 2.5 - 3.5 max down, and .9 - 1.2 up. The gnex has a 21Mbit HSPA+ radio in it, so in theory it should accept whatever AT&T can push to it. However, I came from an Atrix 2, and can vouch for the fact that the Atrix 2 when using the PTA APN on HSPA+ (no LTE for about 200 miles where I'm at) will download consistently between 7 - 9 Mbit... Same server on speediest.net, same APN, same place, the signal is within 1dBm of each other.
Because I have found no base band that can change this, nor any APN setting I am starting to believe that if AT&T gets an IMEI of a phone that it doesnt recognize, they will throttle it.
Any one else have any insight? 3.5Mbit is plenty, but I'd like to get the same speeds as what I consider a lesser device.
If I could find a way to change the IMEI I'd test this theory.
^^^ Suprisingly, Its not att at all. Ask anyone on these forums, samsung has notoriously bad radios. Signal and cell strength just are not that great. And you can you can especially feel the difference coming from a motorola device. They have the strongest radios of all the major oems by far. No one even comes close.

Lack of 3G ? About to return my SGS3 for an iPhone

So is there a "3G" on the SGS3, because I either get full bars and "Edge" or I get "4G"(which is HSPA+) but I never have just plane jane "3G"?.....its starting to bug me because my friend has ATT as well and we will be standing in the same exact place and his iphone will get 3G while my SGS3 will only have edge.....I don't understand why this is? Does the iPhone have different antennas or something? I don't really want to trade my SGS3 in for an ios device, but all the features on the SGS3 become somewhat pointless when I can't really do anything because edge blows ass... So can anyone give me some insight into the matter?

Have you looked in wireless and settings > mobile networks > Network Mode?
Hsdpa and hsdpa+ are 3g homie. The phone calls it 4G however as a marketing tool. If your on true 4G it will say 4G lte.

I would recomend getting a replacement S3 first to see if you have any improvements. If the phone doesn't use 3G or 4G(HSPA+) at all then that is not normal behavior. I have not once been connected to Edge since i got my phone a month ago.

I don't have any of those network settings you are talking about. There is no wireless and settings? I have More settings and then network modes, but there isn't any selection for like 3G 2G LTE etc....
I ran a side by side speed test, and he got like 1.4MBPS and I couldn't even get the speed test to load, but after trying I did and it was like .3 MBPS...
I understand the LTE signal thing, but there is no LTE here and I don't think its coming anytime soon, I am in the military and currently operating out of Watertown, NY so yea... middle of no where.
I think I might have to try and replace it I suppose..I am within my thirty days, but unfortunately I didin't have time when I purchased it so I bought it at a wireless kiosk and they are a bit more of a pain to deal with when it comes to exchanging phones... Thanks for the input guys.
Not sure what's going on with your device. I'm either on H / 4G / 3G and on my iPhone 4 I was always on 3G. Completely different location/network than you, but it definitely sounds like your device is doing something strange.
Try toggling airplane mode on/off. For some reason, ics trends to drop to edge if you don't have a super strong signal.

Actually I have been doing this sometimes, it seems to work sometimes, but not always...
Question : Is there even a "3G" signal icon? Or It always just shows "4g" when you are on 3G and up?

So is there a "3G" on the SGS3, because I either get full bars and "Edge" or I get "4G"(which is HSPA+) but I never have just plane jane "3G"?.....its starting to bug me because my friend has ATT as well and we will be standing in the same exact place and his iphone will get 3G while my SGS3 will only have edge.....I don't understand why this is? Does the iPhone have different antennas or something? I don't really want to trade my SGS3 in for an ios device, but all the features on the SGS3 become somewhat pointless when I can't really do anything because edge blows ass... So can anyone give me some insight into the matter?

It also depends on where you live, the area and the service providers radio towers connection to your device specifically

Depends what phone on at&t siii there us No 3g icon. OK there is one in systemui but it us not used. The phone always shows 4g when on 3g umts or hspda or pseudo 4g hspda+. it also shows edge and 4g lte. I am on a micro cell at home which is 3g and it still shows 4g. The way to really check us to go to system then about device then status and see what network mode you are on. Here in the screenshot you can see 4g but also that the phone is using hspda which is normally 3g in any other phone

Wimax McLovin

I live in Orange Country, California. There's Wimax blanketing the whole county. I love it.
Unfortunately, no LTE yet. ETA mid-next-year.
I, recently, upgraded to the S3. I tried it out for more than a week. I love the phone with all its bells and whistles. However, because there's no LTE in my area, I was connecting to the 3G. And, it's horridly SLOW.
So, I decided to switch back to my S2 Epic Touch and take advantage of the Wimax speed until LTE comes to my area.
Am I crazy? I'm wondering if anybody else have had the same experience.
You're not crazy at all. I'm currently in Orange County too, specifically Orange/Garden Grove. I love the 4G at my work office. My 4G pulls 8mbps down, inside the building. But LTE rollouts in OC shouldn't take much longer, I'll be ready to buy a Galaxy Nexus or S3 when it does.

Nope not crazy at all.. I was actually thinking about getting the note 2 but it's no lte here in DC yet; great 4G tho.. And I use my 4G a lot to tether and watch videos.. So I been thinking about that before I go get it next week
-TeaM VeNuM Like A Boss
Yeah, me no loco!
I really like the current generation of phones. For instance, the EVO 4G LTE has one of the best camera. The aperture is F2.0. Wow! It's awesome for me, because I frequently take pictures of my little daughter. But, that too, I quickly returned, because I couldn't stand the horrid 3G speed.
Yupz, I'm also in Orange County enjoying great 4G WiMax speeds. Not gonna upgrade to an LTE phone until LTE actually gets here.
I Live in craptastic Oklahoma with no 4G I however visited Orange County a while back and was shocked at how amazing the 4G was. At most places it proved faster than the wifi I could use. Can't say the same for a recent trip to St Louis.
Funny such big cities have to wait on LTE, mine will be live by Xmas time and I'm in the sticks. But mines included in like a 1/4 state upgrade covering about 4 major cities and 20 smaller cities. I'm just trying to decide what to blow my upgrade on

If you live in a Wimax area with no lte, there is no reason to upgrade. Its the reason sprint is still supporting this phone I think.
Sent from my SPH-D710 using Tapatalk 2
Frankly, if Wimax and LTE is not available in your area and their 3G is your only avenue, i wouldn't recommend Sprint at all. "Unlimited" data is irrelevant if you're speeding along at a horrid rate. Smartphones need a decent network connection to function at all.
Don't get me wrong, I love Sprint. Their customer service is great. You can get a live person (from USA) customer service within 30 second when calling in. And, their online customer service chat is fantastic too.

It's still a great phone. They might just keep selling it until NV is fully rolled out.
Samsung will keep supporting this phone with software updates until it reaches it's end of life age of 18 months. I would hope they keep software updates coming until the 24 month mark.

I can probably see us getting key lime prime or whatever android upgrade is coming out next. There's literally no reason we can't update if it's not a major update... If it is a major update then we'll probably get a value pack update like the OG SGS if they decide to not give us the full update.
Anyways... I've been saying this since forever but really.
If you're in a non-lte area with wimax and LTE deployment is not coming within 6 months then stick with your current wimax phones.
If you're in a wimax area or non wimax area with LTE coming within 6 months then update when you start seeing NV upgrades or increased 3g speeds (3g speeds will increase before LTE goes live) as LTE should come relatively soon as 3g speeds indicate fiber or microwave backhaul.
If you're on the fringe of Sprint service and get ****e coverage/service then switch to another carrier and come back in a year or two where sprint deploys LTE 800mhz and fills up all those holes.
Where are you guys getting your LTE timeframe estimates?

Being a sponsor at www.s4gru.com gives you privy to a lot of information including estimated launch dates, current progress of upgrades, location of said upgrades, and knowledge on what network vision actually is.
All markets are being shuffled thanks to the SoftBank investment in sprint. There is really no more set dates nor time frames anymore. In fact, Samsung, Alcatel-Lucent, Ericsson, and all the other vendors and subcontractors are moving all over areas regardless of market boundaries. Most work is being done in out NE, East, South, Gulf, texas & surrounding areas along with steady progress in Los Angeles (and surrounding counties) and the San Francisco Bay area.

Phone has no service on Band 2 (PCS/WCDMA 1900)

I haven't tried to root this handset yet. This is my #2 handset. The 1st the screen broke so I used my insurance to get another. I work with phones all day long including iPhones, other T-Mobile phones, AT&T and non-GSM phones such as Verizon for example. I deal with carriers such as T-Mobile, Simple Mobile, H20 and non-GSM carriers such as Boost Mobile. So i'm saying that I basically deal with it all. Now the problem i'm having is my own phone. I set to WCDMA only and i'm on the stock ROM of course. The phone will set itself from Band 4 to Band 2 from time to time however, when it sets to Band 2 there is no service until it swaps back to Band 4. I have troubleshooted and called T-Mobile and Samsung to talk to them to find out whats going on. Both of the handsets have done this #1 and #2. The service menu *#0011# shows that it is on Band 2 and it is receiving 2 to 3 bars of service but the availability is LIMITED. The About Phone -> Status menu shows that it is Out Of Service. And the carrier is unknown. The notifications area shows searching... or no service. The type of network is showing Unknown:0. This only happens on Band 2 WCDMA on my phone. On any other phone it works with no issue. I am wondering why my specific phone is not connecting to this band properly. T-Mobile has told me to contact Samsung. Samsung said they can't help me apparently. So what do you think the reason is why I can't connect? If you need screenshots I can take them.
I have a similar problem with my first note 2. My note 2 gets signals sometime and I cannot get 4g speed. I called up tmobile they where unable to fix the problem. So most likely somthing screw up on your phone and use your insurance to exchange a working one.

Its never worked properly on neither of the Note IIs i've had. So 2 devices with the same issue. I believe the issue is wide spread and there are many others with the refarmed band connecting issue. The phone should have come with the options of 1700 and 1900 WCDMA switching or both. Unknown:0 just means theres no option for it so it doesn't know what to show. However, I can't explain why its happening on the Note IIs only.
Another person, as well as myself, posted about this problem about a month ago. We both had the same exact issue... 4G works, 3G doesn't at all. Edge works, GPS works... 3G DOES NOT send/recieve any data. It has to be a T-Mobile issue and from the looks of it they are trying to ignore it. Honestly it becomes a huge issue when you're traveling and can't always access WIFI or 4G. It's something I would leave T-Mobile for... so they should consider tackling the problem and fix it.

This could be the same issue i'm having due to being in a limited 4G area its mostly 3G.
However, I can access 3G and 4G on phones that are not T-Mobile like AT&T Androids and iPhones and it works with no problem. I am wondering if this applies to the Galaxy S III and Note I also as I haven't tested that out yet. That's why I pointed it out at Samsung.
I wonder if it will be fixed when LTE Radio gets unlocked.
Developers should take notice that deal with the combo WCDMA 1700/1900 handsets to create a switch to go from WCDMA 1700 or 1900 and to use a combo of 1700 + 1900. So we could have the option to switch to a specific band rather than it jumping from 2 to 4 then back to 2 and 4 again.
Are you rooted?
Are you running a Custom ROM?
Have you flashed a Radio from anything other than a T-Mobile Radio?
Is it even safe to flash a radio other than T-Mobile?
Similar problem. Network data stopped sometime this afternoon. Tried sim in my sgs2 and worked fine.thinking of going to tmo store.

Not sure but the issue with band 2 might be LTE related and the nonworking scenarios are possibly just occuring as tmo expands their towers... not sure if im way off or not but I read that tmo is pushing some to 1900 to make room for LTE on their 1700... there for, again just a hunch, band 2 might be somewhat sporadic due to it being reconfiged to accommodate their LTE rollouts
Sent from my SGH-T889 using xda app-developers app
I understand what your saying but its a weird occurrence to only not be working on the SGN-II. When I can hold another persons phone in the same spot with 1900 only and it ends up working. Only thing I can come up with is maybe blocking specific devices but I have no clue. Putting people on bands that don't work properly is something T-Mobile shouldn't be doing. If you for example are on that band and an emergency call comes through well you missed it till your back to the other 2 bands that work. I always root my devices however, i'm a lil scared to due to the fact that I might lose my EFS. Even tho I know I can backup my EFS. But then again I could lose it right after root. I don't understand why Samsung put vital info into a folder that could be removed.
Anyways sorry for the rant. I'm glad to know i'm not the only one with the problem.
The GNII is one of only like 3 phones that come with the LTE "on/off switch" so thats why Im speculating still, again I really have no clue but having read a few topics (like you wanted to know everthing about tmo efs/modem/imei/etc before modding anything) I feel like the LTE rollout and the band 2 issue going hand in hand

I think know whats going on. In your *#0011# Service Menu. When it switches to Band 2 the MCC-MNC change. It shows something like 310 260 when its on T-Mobile but 310 410 when its on AT&T. When on Band 2 for some reason it will swap from 260 on Band 4 to 410 on Band 2 therefore identifying it as an AT&T network. Why is it trying to connect to AT&T? I have no idea.

I personally havent experienced any issues with my data/sms (then again if youre not receiving text/mms then how would one know they are experiencing problems in the first place?)
Because I havent had any issues I havent really tried to test my connection enough to know when im band 2 or band 4 or what exact mcc-mnc changes are occuring... for those worried about messing up their phones they need to just make sure they are always flashing a rom built foe their carriers' phone model and also make sure that each flash performed doesnt affect the modem.. (I know the modem part is hard due to roms being based off newer releases but as long as you are following my first suggestion (verify you are flashing the right carriers' phone model download) then there should never be an issue

T-Mobile's response is: The phone is designed to connect to the best network. Once Band 4 on T-Mobile has no signal while on 3G/4G WCDMA it will flop over automatically to Band 2 on AT&T. Due to the 7 year agreement we have with AT&T you should be able to access the network. However, we have lost a bunch of ROAMING AGREEMENTS recently. "Apparently AT&T DID NOT keep their promise of a nationwide agreement". Therefore your city might be on this list. This may be why you can't access AT&T. There is nothing we can do right now. Its a waiting game on when T-Mobile rolls out improved coverage onto 3G/4G 1700 WCDMA and 3G/4G 1900 WCDMA on its own. So in the future it is less likely that you will be put on AT&T. However, it is still possible. Sorry but we DO NOT have any CeI-Fi devices as I would offer you one as we are SOLD OUT. We don't expect any Cei-Fi devices to be in till this Summer.
So this device is supposed to go onto AT&T apparently and its not supposed to show as Roaming which is why Data Roaming Checked/Unchecked doesn't work.
Thank you! Finally a complete answer lol.
Is it possible to make it so band 2 only sticks with T-Mobile?

Well they sold out of the Cel-Fi once they actually dropped the 2 YR requirement extension and then they got plagued with calls and SOLD OUT. I told her thats not good that means that the network is crap. She laughed and agreed. But look at the good AT&T signal makes me want to sometimes switch but everytime I think of leaving I couldn't.
According to the info I have gotten in my area GSM is approx. 485 meters away and WCDMA is 1,110 meters away in the opposite direction.

LTE Band 2 1900MHz capability
I would like to know if an unlocked Tmobile note 2 has the capability to work on AT&T LTE Band 2 1900 MHz?
I know it works on AT&T GSM-1900 MHz frequency. it will even work on LTE band 17 700MHz frequency.
