Hello guys/girls !
I'm using JIO as service provider in India for my Nexus 6. I've recently noticed my speed gone down drastically. Wondering, I downloaded Signal Spy app and found that, when my mobile is locking to specific tower (Found using GCI code), speed is going down to 200 Kbps (transfer speeds of 20Kbps) but when it is locking to different tower speed is going way up (10 Mbps). Sadly as expected my mobile always locks to the poor tower. So just thinking is it possible to blacklist that specific tower? HELP !
People have been asking about blacklisting specific towers since at least 2013, and the answer for all of them has been the same: it can't be done. The hardware isn't designed to do what you want it to do. All the hardware does it find the strongest signal and connect using that. Unfortunately for you, the strongest signal has the lower bandwidth.
The only advice I can give you is this: you either need to switch to a carrier that has better throughput in your area, or you need to move closer to that other tower.

I have cognition rom and instead of having 3g I have this H internet. It sits on 3g for a milla second then switches to H. My buddy with iphone four is getting way higher speed tests than me, why can't I get 3g and get better speeds?

Since this has only been answered 100 times in the past three weeks...
http://lmgtfy.com/?q=H+instead+of+3g+XDA
AND as far as the better speeds for the Iphone go......you can Google that as well............ I'm guessing your on At&T?
I don't know why but my buddies 3g was consistently hitting 300-350 kbs. The max I was hitting was like 150. We were right next to each other when we were testing this, I guess that the iphone blows the captivate away in 3g reception and speed. Also in the spotty areas he was keeping his 3g and I was dropping down to edge. Kinda disappointed . Had anyone else noticed that the 3g reception isn't that good our is it just my area?

this is why i hate american cell providers, they want you to remain ignorant. it's not your fault but it is funny that people arent familiar with grps, edge, hspa, and hspa+ it is like they are telling you that you are too stupid to understand so you dont need to know.
the cdma providers are the worst. but att should be proud of having hspa, but i think they want to hide the fact that it is not available in all 3g areas. instead they advertise the hspa speeds as there 3g speeds as hspa works on there 3g network. they dont distinguish the two so you think there network is so much faster in so many places
meanwhile verizon advertises the hspa coverage for att as 3g coverage to make att's coverage look smaller. they say they have so much more coverage, if they showed a current 3g map for att instead of the hspa coverage you would not see a big difference at all. also cdma 3g is totally different from what att has and is not a fair comparison in the first place. how can you compare coverage if the speed is not comparable?
Comparing phones side by side with speed test is also not the best way to test which device is faster, especially if they are on the same network. I am annoyed by the input on this device or Id go in depth. Use some google-foo and read on cell phone signaling and theory and youll see what I mean.

so i was in the mall today and i saw that virgin mobile has the htc incredible s when i asked him if it's gsm or cdma he told m that it works on hspa sim card, so i asked him if he ment gsm sim card, he told me no, it's hspa sim card.
i asked him for the frequency and he did not know
what is the hspa sim card?
HSPA supports increased peak data rates of up to 14 Mbit/s in the downlink and 5.8 Mbit/s in the uplink. It also reduces latency and provides up to five times more system capacity in the downlink and up to twice as much system capacity in the uplink, reducing the production cost per bit compared to original WCDMA protocols. HSPA increases peak data rates and capacity in several ways:
Shared-channel transmission, which results in efficient use of available code and power resources in WCDMA
A shorter Transmission Time Interval (TTI), which reduces round-trip time and improves the tracking of fast channel variations
Link adaptation, which maximizes channel usage and enables the base station to operate at close to maximum cell power
Fast scheduling, which prioritizes users with the most favorable channel conditions
Fast retransmission and soft-combining, which further increase capacity
16QAM and 64QAM (Quadrature Amplitude Modulation), which yields higher bit-rates
MIMO, which exploits antenna diversity to provide further capacity benefits.
By July 2010, HSPA had been commercially deployed by over 200 operators in more than 80 countries.
Many HSPA rollouts can be achieved by a software upgrade to existing 3G networks, giving HSPA a headstart over WiMax, which requires a dedicated network infrastructure. A rich variety of HSPA enabled devices - more than 1000 available by July 2010 - together with ease of use is leading to rising sales of HSPA-enabled mobiles and is helping to drive the adoption of HSPA

so shortly said.... it has nothing to do with the simcard.. its the provider who supplies the connection... the salesman was a completely idiot as far as i know... or ive missed some technology
thanks Hawkysoft
i thought it he meant gsm but when he kept on insisting i thought i might be wrong..
thanks again

The salesman was correct but just not good at explaining. The Incredible S has a GSM and HSPA radio. Bell/Virgin does not have any GSM network at all, only UMTS/HSPA. The SIM card is the same technology as with a provider whose network includes GSM. But the Virgin SIM card will never connect you to a GSM/2G network, always 3G. Except when you're roaming.

@cmstlist, you are really confusing people
the simcard is a simcard... it can not be different... its controlled from distance
now i will teach u something
a provider can reprogram your phone by your simcard from distance, turn off your device etc.etc.etc. i know it sounds unbelievable but trust me its the truth.
so shortly said
you put your simcard in the phone,
it will recieve config details from your provider which allowes 2g/3g/4g/ etc.etc.
so basicly its just the provider not the simcard since thats not relevant in this subject.

I don't see why my response would have been confusing. The OP's question was essentially: Why did the salesman say that the Incredible S is not GSM?
The answer is, because Virgin Mobile Canada does not have a GSM network. If you take a Virgin Canada SIM and pop it into any phone within a native coverage area, I can guarantee 100% the network you connect to, if it connects at all, will not be GSM. If the phone you try and use it in has GSM but not HSPA, it will get No Service.
Does that make it different from any other SIM? No. But I think the salesman was just trying to get across the point that Virgin does not have a GSM network, so it would be incorrect to refer to GSM when talking about their phones and SIM cards.
-cutted out- delete this plz

Ahh - well *that* is a completely separate question. Answer is no.
Bell/Virgin is a 3G-only network, and they use the 850/1900 frequency bands.
WIND is also a 3G-only network and they use the AWS frequency band.
The Euro/Asia Incredible S has the bands 900/AWS/2100 and would work on Wind.
The Bell/Virgin Incredible S has the bands 850/1900(/2100 I think?) and won't work on WIND.
I live in Southeast Missouri and it seems that when I'm at work (full bars of H signal) I get horrible data speed. My phone won't even load the Xda app. I've been through about 3 different modems and still get the same result. Is there anything I can do or is Att just f###ing us Android users again?
Sent from my GT-I9000 using XDA App
The Bars indicate the signal strength and not necessarily the quality of your data connection. It is possible to have a good signal but still have slow speeds / poor data quality. It's like that where I work too. I've go good bars but the speed is slow. My coworker called ATT about it and they said they were in the process of getting new towers installed, or upgrade the old ones or something like that, in our area in order to increase the speeds available in the area. ATT told us that they do not throttle speeds but that it was an issue with the quality of the data connection in our area due to the towers in the area and how many people were using them versus the amount of bandwidth the available towers were capable of providing. I hope that gives you a better idea of what is probably going on for you.
I see the H+ symbol on my data speed intermittently in Las Vegas with my International Note. A few minutes, then it's gone, it comes and goes. There was a point at about 4am in the morning where I had it for a good 30 minutes. Can someone explain why that is? I thought the International version is only capable of EDGE on t-mobile. Is there a hack or root that can give me H+ in Southern California?
Please advise, thanks!
A friend told me that tmobile is quietly rolling out 1900mhz in select areas. I'm guessing this is why you sometimes get H+ speeds on the note, which doesn't officially get it nationwide on tmobile network. It's good news but it doesn't mean you will have 3g or better speeds everywhere.

several factors could be the cause
If network has fast dormancy and its switched on(default) then the phone will role back to lower speeds until you actively use network again. It is then a feature not a bug.
Could be reception of data network in city theoretically reception could be lost/weakened by buildings, moving or standing still traffic, etc. Anything from cell tower reach to phone to anything obstructing the radio waves.
Could be battery saving app
Could be settings on phone to conserve battery
Could be buggy modem
etc
Given these you can eliminate. If you battery and speed when using network is not adversely reacted then ignore
edit: roaming on other network could also be a cause. Best switch that off(is default off)

Great work. Should be useful to Sprint users.
You can skip the computer part if you install logcat and begin at step 5 after launching.

Wouldn't battery use increase from enabling this? Because it would be constantly scanning for the other 2 frequencies?

sweet!! thanks been wanting to get my MSL since i got the phone.. just hate talking to sprint reps to get it.. worked great thanks!!:good:
i live in fort worth and set 41 to 1 and the others to zero and i have lte , so does mean i have tri band in my area? and will the other bands set to zero still be used when needed . thanks

True enough, but you need to get the right logcat app, some don't work as well as others. I initially tried aLogCat, but didn't seem to work. CatLog app worked great, however.

Just saying. No one has been able to get a B41 (TDD-LTE 2496-2690) connection with a Nexus 5 and that's with actual maps of Clearwire sites that's been upgraded and knowing where each site is located at. I've personally visited over 24 sites to no avail and know of others that visited many sites as well. Looks to be a much bigger issue than just changing up the LTE Engineering settings and may be network related.
Just got the phone but I'm pretty disappointed with the LTE speeds 1/2mb down, outside it's a bit better. Went downstairs and it disconnects from LTE altogether. Anyone know if it's a radio (hardware) issue with the phone or firmware radio? Some spots of my house won't even catch LTE, whereas my s2 would get wimax.
I've tried spark but it makes my connection more unreliable more pocket loss, but indeed it does seem to make it faster, placebo? I'm in Los Angeles don't know if it's been rolled out. I tried updating prl/profile to no avail. My next choice would be to try the LG 2 in hope of it having a better radio.
GPS is spot on, and wow this thing is fast!
Just a question, but wouldn't prioritizing band 26 make more sense since that is the 800MHz frequency band?

No, band 41 has the most capacity so you would want to connect to that if you are actually in range of it. It will automatically drop you down to the lower frequency bands as you move out of range of the higher frequency bands.

Sweet, thanks for the explanation!
Hello, I tried this on my N% for Sprint today. btw. I live in N. OC, near Los Angeles. If I happen to be in and out of spotty LTE coverage areas. Will these adjustments cause more battery use or or worse performance?
When viewing HD youtube videos, it seems to play smoothly for a while, and then pauses as it the speed is going and up and down or being throttled.
About Band 41
So you means the Band 41 is unopen under default setting?
we need to open it by manual?
You know, the biggest mobile carrier China Mobile's 4G is TDD-LTE, and also use the band 41
But if I use the 4G sim card, it still work in 2G.

I am with uh60james spark seems to offer more throughput and less disconnects.
I drove to Corona from Carson the other day and i was shocked how much coverage sprint has improved on. I wasn't able to stay connected to LTE on my the entirety of my drive but it is impressive how Sprint has extended lte coverage around corona at least on the freeway.
Spark works better for me, less drop offs.
I am in Naperville. Will check this out and see if tri band goes this far out west from chicago.

I haven't heard anything about DFW having Spark anytime soon, so more than likely not. I live in Arlington myself, and would love to see this area Spark-enabled sooner than later.
Enabled this on my n5 a couple weeks ago .... dismal speeds on lte in downtown Los Angeles as usual around 4 down and 2 up.... Yesterday for the first time spark kicked in and I got 44down and 14 up. BUUUUT today its back and slower than ever. around 2 down/1up on LTE

Seems that due to Nexus 5 lacks TD-SCDMA for China Mobile 3G, it is very hard for Nexus 5 auto connect to LTE.
You need *#*#4636#*#*, change mode to "LTE Only" and wait connect to band 41/38 cell and then change it back to "LTE/GSM Auto (PRL)".
After it, you will on LTE until one of following happens: no LTE cell signal; incoming call; make a outgoing call. If fallback to GSM, you will need another round of "LTE Only" settings. Please check some chinese forums, there are plenty of guides.
It seems N5's baseband firmware did not implement some directly GSM to LTE function and do not support China Mobile 3G, so ...
