Evo - Won't stay in 3G coverage

I'm having trouble with my EVO staying in 3G coverage. My phone is fully rooted and running Froyo (The problems were the same with the Eclair build however), have the 2.05+ radio installed (however the problems were the same with the 1.39 radio as well) and I'm living in Michigan.
At any given time my phone will slip into 1X coverage and will seem to lock in there. When I first received the phone I felt like the phone quality was subpar compared to the Hero I had prior. I'm not sure if its been a firmware issue or network issue or simply a phone issue (starting to think the later), but hoping its a simple fix with something else.
About a week ago I was on a trip across Michigan which should have had 3g coverage the entire way (I was a passenger and trying to use wireless tethering to do some work along the trip). I would constantly go into 1X and would have to restart my phone to get back in 3G. Even at home I'll go into 1X and will have to reboot my phone to get it back to 3G.
I've tried Real Signal as well during these times and it also shows no 3G signal.
Anyways, anyone else experience this? Is it likely a bad radio or something else. I hate to have to return the phone and go through that process plus root again but I might have to at this point.
Thanks for any help that can be provided!!

Hmmm, whereabouts in MI? I am all over the south east and have never seen my phone drop out of 3G yet.
Have you tried wiping everything and trying stock rom w/OTA 1.47 just to make sure it isn't the ROM?

I am having the exact same problem. Using 2.0xxx radio and Fresh 0.5.3. I recently exchanged my phone and got a new one. The first phone did not do this
Try this:
When it shows you no 3G coverage, instead of restarting, go to-- SETTINGS> WIRELESS & NETWORKS> scroll down and look at "Mobile Network". When i get the 3g problem it says "Connection Failed". I think uncheck that box and re-check it and it connects back to 3g again (for a time, but then I have to do it again).
My MOBILE NETWORK settings are: Data Roaming = OFF, Always-on mobile data = ON, and CDM Roaming mode is set to: SPRINT only. Call guard = ON but i dunno what that means.
I dunno wtf is going on with this. Im in Houston and this issue is really pissing me off because i actually got a Novatek screen this time and don't want to risk taking the phone back and getting the Epson...
Anyone else experiencing this retarded issue?

Elegant: I'm in SE Michigan as well. I've tried several roms and have had issues with them all. I'm currently using a Froyo rom with similar issues as I've had with stock and other eclair roms.
As for checking/unchecking the box as you stated in Froyo I don't have that option available... I'm sure there's another way to get to it but I can't through settings. I think there was a #* code to get to where you are talking about but I'd have to look again.
It is a very annoying issue and like yourself I don't want to have to return my phone if there's a simple fix.
On a side note: How do I find out what panel I have? I've been considering the kernel that would get rid of the 30 fps cap but haven't yet pulled the trigger in part because I don't know which panel I have - and because I need to learn a little more about it before I go ahead with it.

Post 3 tells how to determine screen

Thanks for your help - got the kernel and now get around 40 FPS. Now if I can just figure out why the phone goes in and out of 3g on occasion. Its really not as big a deal when I'm at home but when I travel it is a pain.

well i returned my phone and got one with an Epson screen. im using Fresh 1.0.1 and it is even worse. i cant even use 3g data for more than 5 seconds before it disconnects. i've read some stuff about APN but dont know how to refresh/update them. i've updated PRL and Profile and nothing helps. how am i having this problem with 2 phones running 2 different ROMs? last rom was fresh 0.5.3 and now it is fresh 1.0.1...
anyone help with this APN issue? (i dont even know what APN stands for)

i actually am using the kernel for 55 FPS for Epson screens. would that be a factor either?

I'm and having the same issue with 3g.
Every thing worked fine with the first stock root of 1.32.651.1, PRI 1.40_003, PRL 60666.
With the second root of 1.47.651.1, PRI 1.34.651.1 now my 3g is unstable.
I don't know what FPS has to do with any of this, but I put radio radio-1.39.00.04.26 and it seems to improve a tiny bit, but I don't know how to update back to PRI 1.40_003.

Not happy
Also having problems in SE Michigan. Just started today after installation of Fresh 1.0.1 and the new radios. I also have a co-worker with and unrooted EVO and the latest OTA/Radio with the same problem.

I have a rooted EVO (DC 3.2.3). My wife has a stock EVO (fully updated).
Last night our phones started bouncing between roaming/sprint 3G, while we were sitting at home.
We started getting this error if we turned off Data Roam:
"Data Call Failure
Error Code 67: Registration failure. Your PCS Vision username and/or password may be incorrect. Please try again."
The error pops every time it tries to connect to Sprint's mobile network and fails.
We also live in Michigan. Perhaps they are doing provisioning?
Rebooting + update Profile/PRL seems to help, sometimes, but not permanently.

I am having the same issue with my 3g coverage.
When I go into my settings and turn mobile network on, it connects but then immediately says connection failed.
Does anyone have any suggestions as this is getting really annoying and frustrating.

Went to a Sprint store last night; apparently Michigan was having some significant network issues (the store reps said their phones kept getting disconnected as well), and that it was expected to be resolved by sometime today. After a reboot last night, I haven't had any more issues myself.

No signal, T-mobile, WCDMA

So i rooted my phone over a week ago, and tried out many different roms. Everything was going fine, until i noticed yesterday that i kept losing voice and data connection. I tried updating to the latest radio which was out today 5.09.00.20, but still have the issue.
The only workaround i've found so far is to set the network mode to GSM only. But obviously it's not very practical for a phone like the desire. When i have it on GSM/WCDMA Auto, it keeps voice and data on for about a minute, then i lose it. And when it's on, i still can't make any calls. But i can make and receive calls fine on GSM only.
Anybody have a clue what's going on here? I tried calling T-Mobile, but they were as useless as always. Apparently there was an issue on the 29th, which is now resolved, and they refreshed something on my profile. So i dunno if rooting/flashing my Desire has caused this or if it's some network outage.
I'm currently running the latest DeFrost rom. I've tried SenseFroyo (Opendesire), LeeDroid & i'm now running the official 2.2 sense rom.

I've also been having problems when connected via 3G for the past few days, but only when I'm at home (so I think it's a specific cell). The signal indicator shows a good signal but attempting to use the internet over 3G just times out, and my voice calls keep getting dropped.
Like you I can work around the problems by switching to GSM only.
I think it might not be a problem with my phone though, because I've tried putting my SIM card in my Nokia N95 and the internet doesn't work over 3G on that either (internet works using GSM on N95). I did manage to make a call on my N95 when my Desire was dropping both incoming and outgoing calls within seconds though.
Weird! I'm going to give it a few days and report it to T-Mobile if it's still happening.

It's fixed for me now. I guess it was a network outage

[Q] phone will not let me do anything while roaming. any ideas?

so i was running the VR_GengerSense_Revolution_B4 rom about 4 days ago with now problem doing ANYTHING on my phone while in digital roaming. then i left the roaming areas and went into sprint service area and came back into the roaming area and now my phone wont do anything while roaming. i cant make or receive calls or messages or use any apps or the net. i have 2-4 bars of signal but if i try to do anything it tells me i have no network connection. yesterday i switched to the BeKinged-STOCK-Beta-V1-Clark44 rom thinking that changing everything would fix it but it didn't i went back into that same roaming area today and its the same story. does anybody have any idea of what i could do to fix this? I'm at a loss i tried every setting and was on the phone with sprint for about an hr. and nothing. Ive tried different radios and still nothing. i was thinking of un-rooting and seeing if that changed it. it baffles my that it just randomly started with out me changing anything on my phone.
thanks for any input.

i updated the PRL tonight hopefully that will help \. gonna try that before i un-root.

PRL update didn't help. unrooted taking it to sprint tomorrow.

[Q] Cant text at home unless roaming on Epic Touch

So this is my last hope for a solution to my problem. I got the Epic 4g touch almost a week ago. Had Sprint activate it and everything worked for the first 48 hours great. Three days after I got the phone I came home from work and could not send a text message. When I would send a message it would immediately fail and would receive old texts from people over and over. Very rarely a text would go through but then it would stop working again. My Voice and data works fine no issues. So I called Sprint tech support probably 10 times and they had me update PRL update profile they refreshed the data, disabled texts and re-enabled, factory reset. Basically everything they could and I told them I live in a apartment on the first floor next to a main highway and the coverage map says I should have near perfect signal. So they checked for outages and submitted a ticket to check the tower which came back as fine. When I am around town everything works including texts just when I am at the apartment the texting does not work. So Sprint sent me a Airrave. I went from 3 bars to 6 but still no texting. I rooted the phone updated the base-band to FB27 and my PRL version is 61086. So basically I am at a loss. One of the Sprint techs told me it could be a blockage from the concrete slab on the apartment but that makes no sense considering I have another t mobile phone and my roommate has a Verizon droid and neither has had problems and I can get 3g data and voice fine. I downloaded a program called Roam Control and when I am roaming in the apartment texts work fine but I do not want to have to roam all the time for texts. If anyone has any suggestions and could help that would be great.

i have a similar issue but mine is just that i dont get service in my home :/ i would suggest you sign up for google voice if you dont want to roam. Google voice is free for sprint user and you can text from your computer or anything with google voice such as a ipod touch. Also google voice has free visual voice mail. https://play.google.com/store/apps/details?id=com.google.android.apps.googlevoice&hl=en

I would say hook up your phone to google voice. There is an app also in the play store to allow texts as well as voice calls to go over your wife instead through sprint. Maybe your phone is messed up?

Also try a third party sms like handcent chomp or go sms

I don't think it is the phone because it does work everywhere else. Its like bafling the tech support people. But I will try google voice. Does google voice texts show up from your number?

This will solve your sms issues..
Do you have wifi at home? If so download "text plus" from the market. It's free. Works for me. I live in a dead zone and text plus sends texts every time! Hope that helped.

Are u experiencing any issues with network connection?

My s3 randomly loses connection to the network. Today I picked up my phone to make a call and noticed it was not connected to the network and displayed Emergency call only message.
This happened a few times before too. Initially, I thought it could be a buggy sim so I got a brand new sim from telus. But its still does it. Randomly though. Any thoughts guys?

Anyone?

I haven't really noticed any issues, but I'm on AT&T. What ROM/firmware/modem?

I had similar problems till i disabled LTE. It was trying to connect to it all the time plus it was killing battery.

me and my brother have had the issue in dowtown ottawa on rogers. seems fine in my apt in the market but on a patio and at a restaurant it just wouldnt work!! couldnt send texts, or receive, couldnt call, sometimes it showed i had full bars and lte but couldnt do anything. my brother complained about this the day before. i will try disabling lte next time
