(Question) signal strength

I jut wanted to see if anyone could give me advice on having better signal. What exactly effects thesignl strength? I know its the prl and I believe I also read that the modem hassomething to do with it also. I've tried different modems I can probably say the best I've used was ec05 but I'm running eh17 now and I update my prl every couple of days. I be in my basment a lot ad I get a lot of call drops or don't receve calls at all and I get texts late or don't receive them at all either. Ifanyone knows anythin I can try that might fix these problems it would be really appreciated. Thanks.

Try updating your prl manually... there should be a guide in the devolpment section.. and the issue can be your basement.. I get great service in certain areas of my house but the basement usually only gets good service if I leave my phone alone and don't move it.. so it has a steady signal- that could be your issue too. Updating your prl manually isn't easy for beginners so what I would do is read the instructions very carefully

it may be because of my basement but I used to have 1-2 bars but I switch roms and try new modems and now I usually have 0-1 bar in the basment. And even when I am outside I still sometimes miss txts.
I read that thread once it waspretty confusing.. probably because I wasn't trying it. But the thing thatmade me not try it was the face that I have to choose the prl number that I want so I have no idea how to tell which one is best and even by reading what ppl say tey might be in a different place where their prl is better. So I'm really not sure about what to update the prl too and I honestly don't really know everything about prl. So I won't be messing with it until I really understand it.

1. Buy Roam control @market
2. Set it to roam only

Well the prl is the Preferred Roaming List so if your issue is when you have no signal, which other providers tower will you roam to, then the PRL matters. If your signal in your house is just terrible then it could be some new construction in the area messing with your signal. You could ask Sprint for an Airave if you complain that you have no service in your house and if you have enough credit for an additional line it will cost you the difference in taxes for another line per month. In Florida that was another $1.72 a month. Or as suggested try Roam Control.

I did this, and am supposed to get an airave sometime this week. I also use Roam Control in my house where the signal is weak. Hope to be able to just stay on Sprint with the Airave.

Yes. It is called a Femtocell. It is like a mini cell tower in your house that uses the internet to complete calls.

Yes. Provided you have enough credit for another line. It is usually lent to you with the idea if you no longer need it you will return it. I have seen them try to charge those with not enough credit to qualify for an additional line. I qualified for 8 lines so had no problem getting one. Just have to pay the taxes on an additional line which depends on the state you are in.

.12Mb/sec roaming

Description says it all. When I roam onto Verizons towers I only get. 12Mb/sec which is almost no internet at all. Is there a way to fix this? I know the signle from my tower would give me 2.5-3Mb/sec on my evo just a few weeks ago. Ideas guys? Oh i use Roam Controle to switch over to Verizon if that makes a difference

yeah well the best Sprint 3G I can get in my neighborhood is about .25 Mbps. And it's true for many parts of Manhattan, you can't crack .5 Mbps.

I thought verizon dramatically throttles it for roaming.

I dont use 3g much in Manhattan. But where I live(in queens) and where I work and go to school (midtown) I have an awesome 4g signal. When I'm inside, I average anywhere from 6-9mbps and when I'm outside I get about 9-11mbps

Damn you 4g'ers lol. Kauai doesn't have 4g yet

It all has to do with the 3g radio in the phone...It sucks...I'm in Dallas TX and I get speeds so low I can't load a web site through opera mini. Any other phone I owned Evo4g and 3d where not that slow at all. 4g is not strong enough to keep a signal while moving/driving so I dont use it much.

Actually, it has all to do with your prl...unless you're on an old or select business prl, almost all current prls only allow 1xrtt data on roaming. So the speeds you are seeing are actually normal 1x speeds
Its confusing though, since our phones seem to be lacking the 1x icon

Actually in many areas, the PRL entry for Verizon is defined to search for Verizon 1x signal while also searching for Sprint EV signal. So you could actually be roaming on Verizon for voice, have the EV/3G indicator, but still be using Sprint for EV/3G data.
This can lead to even more confusion.

LOL I normally get about .20mbps on Sprint's terrible 3G network, and still no 4G here in Phoenix.
You have to admit Sprints 3G network is a joke. I was sitting at dinner earlier right next to the tower and I was barely breaking 1mbps.

My Moment (August, anyway) was able to roam on 3G in northern Wisconsin. Of course, I believe that that part of AllTel went to Cellular One, not Verizon. That's probably the difference.
In fact, I often got better data speeds in the middle of the forest up north than I do at home in Milwaukee. I usually got 150-200kBs (bytes, not bits) whereas at home, I get 15-20kBs.

speed heavily depends on time and location
can be anywhere from 500kbs-1.5mbs but as slow as 200 if the tower is super hogged.
Never had a LOS, stock kernel + root

Damn I would kill for those speeds. In midtown manhattan and on 4G I can only get around 5mbps download (standing next to a window) and 350kbps download.
I can't even get 4G signal in my house downtown. I get only 1 or 2 bars for 3G unless I am standing next to a window.
I need to test the speed of the 3G next time I roam.

this is fps test. hope the pic works this time

From what I understand Verizon does not support 3G roaming with Sprint phones you will only get 1x service. 3G roaming was a deal with Alltel, who got bought out by Verizon and ATT. You are going to get crappy speeds if you are roaming on Verizon.

Sprint Network Down?

I'm in So Cal (The Valley to be exact) and my phone has had NO service for a few hours now. When I say no service, I mean NO service, I get the circle indicating my device is searching for a network. When I reboot the phone, it connects to Sprint but I don't have any signal. Then soon after that, I COMPLETELY lose service. Hopefully maybe nearby towers are being worked on. Though, seems unlikely at this time of night, AND i'd still be able to connect to another nearby tower. Anyone else having any service issues?

Sprint is going their network vision updates throughout all of la county right now. Trust me, the blackouts are worth it. They're doing work on the towers near me and my speeds are easily topping the 1mb download and upload. So far I've maxed out at a little over 2mb download and 1500kbps upload! I average around 1500kbps down and 1000kbps up. Your signal will be a bit iffy for the next few weeks though.
Edit: there's a new prl update it and at first u had crippling speeds but as I began to use my 3G more, my speeds are increasing. I was freaking out for a bit but just another heads up.

Yup expect that for the next month or two. When they worked on the towers near me, it was usually in the early morning. I usually had voice but no data. I say be patient, the speed is worth it. I love being able to clearly stream YouTube videos and Pandora now.

I use to work for sprint. Climbing towers. When I was there we tried to get the work done with least impact but a lot of it is driven by sprint's request and how many people are using the tower. If you have consistant LoS call sprint and ask them to check the tower or ask for them to open a ticket for a line sweep. Some of the times we had bent cables, which will block a lot of the signal.

If you're actually getting 150-200KB/s (aka 1200-1600kbps) then that's absolutely fantastic for Sprint 3G... People are used to ~400kbps tops.

I tend to get between 25KB and 60KB a second. Once I got 1500Kb/s. That was pretty cool. I remember the days of T-Mobile EDGE though, which would be 3 to 7 KB/s in my area, so I'm quite content.

Agreed PRL 25010 for my device has given me nothing but problems. Starting around the 15th for me my device will periodically will not pass incoming calls to the phone nor incoming texts. All data works fine, all outgoing calls and outgoing texts work fine.
Also tested it on my EVO LTE and same problem happens.. Sprint support sees a high percentage of what they call blcoked calls (calls not making it to my device) and they cant explain it. 11% today, 25% on the 15th. She said anyhting higher then 5% is not good.
Ive already been told by another XDA member that PRL has nothing to do with it. BUT i think thats wrong. All this happened around the time the new PRL dropped. Call it a placebo affect but my data services and signal strenghts are lower across the board lately.
On both the GS3 and EVO LTE, and they both have the PRL 25010.
Taking it with a grain of salt tier 2 tech told me that they have seen a higher volume of issues related to call problems and data issues in areas with network vision and i told her i thought it was related to the PRL and she agreed, but we all know how those calls can go.
Prior to the update i had no service problems and was seeing the fastest 3G speeds ever (in dallas, tx and i get faster 3G and seeing more 4G LTE) I feel like im back on the old sprint network prior to all these updates.

After you updated the PRL, did you update your profile? If not, perhaps that may help.

Yup.. Today we did multiple data resets ##768 what ever the rest of the numbers are..
Did it twice and a few hours after each time im still not getting calls into my device.
I have done profile updates before and after PRL.

Are you in Baltimore area? That would be the only change in native Sprint service between PRLs.
What SID are you connected to? Check your ##debug# screen in the 1x section to find out.

dont have the passcode its looking for when i put it into debugging. MSL code doesnt work.

Type in Sprint for the code. In numbers of course.
-- "Sensorly or it didn't happen!"

So after doing a lot more research i found out how to load a PRL to my device.
I was on PRL 25010 and am now back on 25009.
Guess what, my data speeds are back up to over 1meg on 3G. (yes that was a sarcastic guess what by the way)
I dont care how many times certain users say that a RPL doesnt affect speeds or connectivity. Call it a placebo affect.
Since 25010 dropped on us i have had nothing but crap tacular data speeds..
I was unable to get over 500k down on the old prl..
3 times now with the 25009 prl i have had 1.12 megs, 1.0 megs, and 975k down.. Ping times are also a lot better..
So problem solved now that i know how to go to an older PRL..

The only recent change Dallas really had was the addition of 800SMR several PRLs back, even before the EVO LTE or S3 was launched. Probably what you are seeing is really Network Vision upgrades and such. Are you running a ROM that has the 3G/1X icon fixed? If not you could actually be on 1X instead due to some of the upgrades. And it is very possible to now only have 1X coverage in areas where you were roaming before. Enjoy the 800SMR... I'm jealous!

On my gs3 and evo lte (I switch back and forth periodically) I noticed a degradation of service from 25009 to 25010.
Both units stock. Non root.
Use the same server for speed test.
Same location. Either my apartment in my tv chair or office at my desk.
I do have mobile signal widget and network signal info to monitor my data connection and strength.
Several months ago my evo lte would get stuck on 1x. But that was several software updates ago. They fixed it. And when it happened I was well aware of it.
I'll enjoy my placebo affect and chalk up the better performance on prl 25009 to colder temperatures. Lol.

Forgot to add. Roaming is set to sprint only. So I don't roam.
