Sprint roaming issues

I had been using Sprints ROM for some time but I got the itch to try a new ROM when I was on duty in Montgomery, AL. Montgomery has excellent EVDO coverage and I never have to roam. I started noticing a problem when I went home to Decatur, AL where Sprints network isn't so great. Every time I was roaming and I would send a text it would immediately fail. I didn't notice the roaming=fail issue for a while but when I noticed it I put my phone on home network only and all is well. Unfortunately at home I roam nearly all the time which means no texts or calls. I would have to leave my phone on home network and basically could only send/recieve texts in certain locations in my home. Well a week went by and I kinda just lived with the issue... I tried to make a phone call roaming and got this message, "Welcome to Verizon Wireless. We're sorry, we are currently unable to authenticate your phone. Please try your call again. If you continue to experience problems please hang up and dial #8899 from your wireless phone. Announcement 11 Switch 113-5." Just recently I flashed to DCD's latest rom and have the same issue. I use USB to flash my ROM... I tried dialing #8899 and it gives me an automated menu but it doesn't say Sprint or VZW...
Anyone have a clue on how to fix this?

anyone have any suggestions to point me in the right direction?
I really needed to make a phone call last night but I couldn't cause I didn't have any sprint signal... tried like 10 times on roaming but kept getting the same error..

Got it fixed. Had to spend 2.5 hours on the phone with Sprint. Changed settings on the phone about 50 times... finally they did something on their end. Lady said they had to cancel my account and recreate it to fix it in the system. Oh well.

For completeness, I think the thing you had to do was get an HLR Reload.

Rogers 3G network

Hey guys, I just wanted to see if anyone else is having a longer waiting period with the Rogers 3G network lately or if it is just me. I've been noticing that my phone has slowed down quite a bit when browsing the internet or using an application that requires data on the 3G network. My wi-fi is fine, just the 3G. It takes between 45 secs to 1 minute to retreive the information. I had called Rogers and asked them to reset or refresh or whatever they do down there, but didn't seem to help.
Now if it is just my phone, maybe it is some application that is using up the processor or data, but I don't have that many applications running in the background other than weatherbug that constantly uses data.
Any suggestions would be helpful.
Thanks

What happens if you run a speedtest? the app by Xtremelabs is good.

no issue here. i use mine on a daily basis between pickering and mississauga, and as long as i have at least 2 bars of signal strength my magic is very fast over 3g

Thanks guys for the quick response. I think I found the problem. I had called Rogers support again and they said that it is due to my sim card being a 2G one. I need to replace it with a 3G. Hopefully that will fix the problem.
Thanks

I too have been having internet/email issues since last Thursday using my Treo 750. The symbol toggles between 3G and H and usually does nothing but comes back with an error message saying something like 'cannot find this page...'. I travel between Oakville and Concord every day with the same issues. The phone worked perfectly in Brantford last night...so I don't think it's a hardware issue. The tech support guy grabbed a treo and tried and was able to connect on EDGE....not 3G.
I tried my sim card in my sons Motorola Risr and it works perfectly....on EDGE. They tech support guy said they were having issues with 3G last Thurs/Friday, so I'm wondering if whatever they did last week is affecting some older phone models (I've had mine for 1 1/2 years now). Not sure if I can (or if I want to) configure my treo to connect via EDGE instead of 3G...
Anyone having the same problem?

Very odd indeed. I got my new sim card but still doesn't fix my problem. At least I'm not the only one experiencing the same problem. As far as I know, the 3G and H symbol are he same thing according to rogers tech guy, correct me if I am wrong. I'm going to call again today to see if I come up with anything.

Just got off the phone with Tech Support again. They are sending me a new Sim Card, but from the sounds of it, that's probably not going to fix the problem. He WAS going to do a free hardware swap until he discovered the phone is out of warranty. Then it was basically "oh gee, three year contract, one year warranty...tough luck".
Yep, the G and H are the same thing. Since mine is switching back and forth, he said the phone is hunting for a signal.
When I asked why the phone worked perfectly in another city he couldn't give me a good answer. I have to go back to Brantford tonight, so I'll get a chance to repeat the experiment.

Listen folks. It has nothing to do with your SIM card, nor your phone. The reps at rogers, I for one, ASSUME it could be the sim card, but really, most of the reps cannot differentiate an incompatible SIM with a compatible one, so they send you out a new one anyways, just to get you off the phone because they really don't know what the cause is and they have no hands on the status of the networks and network problems other than what is posted in library by the actual IT department, which do not directly communicate with the centers.
To sum it up. Rogers 3G network is garbage! and that DNS issue is not isolated to the metro area, it's here too in Newfoundland. DNS resolution is extremely slow, even with OpenDNS, which means it's their switches that are garbage and most likely being bogged down. Rogers thinks they had solved the problem by throttling the 3G bandwidth to ~3Mbit and the upstream to less than 150K, (My assumption), however, that isn't working.
From my guess is that the request is sent to Rogers networks, which cache that request then caches the pages and sends it to your device, making it appear you have a fast connection.
Anyways, sometimes I find the EDGE network a lot faster..especially in the DNS resolution area.

"It has nothing to do with your SIM card, nor your phone"
My feeling exactly. It just seems a little too coincidental that everything was just fine until they had a network "issue" late last week.
So, being a mechanical guy with very little knowledge of how a these things actually work, is there a way for me force the treo750 to use the EDGE network?

Never mind, I got a hold of a guy at Rogers who seemed to know his stuff. He told me to get the latest OS from Palm and then how to go in and set it up for EDGE. We'll see how that works.

I love ripping on Rogers for being crap, they are, but the network is downtown Toronto is far from crap. And it is not throttled. I have had repeated speedtests reach 3900kb/s with the average around 3100kb/s. Thats not too bad considering the crap they put up with in the states on AT&T.

True, compared to the 3G in the U.S I would agree that Rogers has an edge, 3G here in Newfoundland is still in it's infancy, well still is everywhere. We just got 3G last winter I believe.

what newfoundland has 3G?
now hell really has frozen over (ha)

TMob US - 3g service, but no internet

Ok, this is goofy.
Wifi works great
EVDO connects to internet and works great
3g shows 3 bars, but will not connect to internet
This is true even after a hard reset. Must be a settings issue? I did a hard reset, let it set up, and still same problem.

I got the same problem. Purchased the phone yesterday morning. I never had the data plan before. I called T-Mobile twice and they told me that it can take up to 48 hours for the data to kick in. If it doesn't work by tomorrow morning, I'll give them a call again.

i got the same thing too guys. it is fine now and i got a text message from tmo so it it cuts out again i will chime back in.
buy yeah, yesterday i lost connection twice for long periods of time, like a couple of hours.

Thanks for the info! Seems pretty weird that it works when I'm in an E area, but not on 3g. Maybe different towers or something. Friggin awesome phone though!

LOL, WTF
i just tried to go on yahoo on my hd2 just now after posting and guess what.... it's out again!

OK so I pulled the battery and popped it back in and my internet is back.
i hope this isn't a hardware issue!

Yeah, this is interesting. Popped my TMo sim into my Xperia, could only get E level of service for some reason but could connect to the internet. Put the sim back in my HD2, took it to the far corner of the basement where it drops to E service and it connects to the internet. Back in 3g zone and it won't connect at all. At least it seems to have a stronger antenna than the Xperia. I'll have to give them a call and see whats going on.

there was an issue with the settings...
you can try a couple of things first...
if you are familiar with windows (which sounds like you are), you need to go change the access point name (apn) to one of 2 options...

epc.tmobile.com

I called into customer service about same issue. I was told to power down, remove battery and start it again and check. It worked afterward.
Maybe it was due to them activating my new data plan, from Android data to Smart phone data. I don't know, just guessing.

I thought maybe I was having this same problem yesterday..
thought eh its all in my head.

This is tmoUS, guys. They're notorious for having ****ty 3G service. No point in having HSPA+ when the majority of the people are still reliant on EDGE. Hopefully by summer you guys will get decent coverage.

I'm in NYC. The 3G is good here. Rarely had problems. Probably only a day or something that I can remember.

spotty here in denver. got mine last night. can't get any gps satellites for google maps either.

It was set to epc.tmobile.com
I tried to change it to wap.voicestream.com, but that setting errored out.
Then couldn't get the epc.tmobile.com setting to work which is strange. Soo, did a hard reset and let it set up again. Same thing. I can connect to internet with Edge, but 3g even though it shows the signal bars and everything seems great will not connect to internet, download email, update weather, etc.

I too am have this problem... Sometimes web works great, other times no web but strong 3G.... I thought I was going crazy...

My internet was working really slow yesterday when I first got the phone (5-60 kbit/s). Called up tmo to ask if maybe they had set me up with just tzones or something. The guy said "no everything looks fine here...oh wait I see there's something that needs to be reset; I'm surprised you were getting internet at all." When I asked him what it was he said he "couldn't really explain what it was", to which I replied "..."
Anyway, it seems to be working fine now. Don't know if this could be related to the problems you're having, but giving tmobile a call couldn't hurt, maybe they can flip the magic unexplainable switch for you.

Ok so I couldn't get internet for two days now, I called T-mobile twice and told me to wait 48 hours. After thinking something was fishy, I looked at my receipt from Wal-Mart where I purchased the phone and I noticed something peculiar: "REQ Android Web: 30:00". Knowing damn sure I did not purchase an android phone, I called T-Mobile for the third time, complaining, so the first guy transferred me to another operator. He checked out my account and it turned out that I didn't have any data plan at all. So he added the plan and within 20 minutes I was surfing. Everything works great. I'm getting about 850 kbps in northwest Indiana.
It's very interesting that the first two operators I called never even bothered to look at my account to see if I have a data plan.

Just discovered new regarding the no data issue.
I had the no data problem again today, even though it was working in the morning. I decided to reboot and check, but then I noticed the 'Terminate Data Connection' option when I hold down the power button. So I tried it. It killed the data connection and when I went into Google Maps, the data connection reactivated and everything was fine again.
So, it may be a bug!

Best Way to Test Signal

Can anyone suggest the best way to test cell signal on the S7 Edge? My wife and I both have the same phone, but hers consistently seems to report more bars in the same location. I've had calls drop quite often on the first dial and then they stay connected the second time I call. I'm looking to test both phones and see if it's all in my head or if there really is an issue with my device. Any help would be appreciated on an app to use or other way to test the two phones. Thanks.

did you try phone info fromthe play store.
under monitor it will tell your signal strength. I believe through its service menu you also preform a signal test.

Yeah, but those numbers don't mean anything to me. Other than saying moderate for level, it doesn't say much.
Edit: My wife is not home right now, so maybe I'll install this on both phones and see if there is a difference in the same location;. Just wondering what options are out there for testing.

when you look i phone info under signal strength the number tells how good your calling capability is,
It is measured in dBm.
average should be should be around -101 dBm for full bars depending on your provider.
compare it with your wife's signal strength.
Keep in mind that software plays a part, please check that base band version and csc is the same.
Different base bands and csc means that signal strength can vary.
These should be identical as these two items communicate with your phone provider re reception and transmission.

Phones are both stock. Same provider and same software version. I'm pretty sure I've got reception issues because of the dropped calls. Like I said, she's not home right now to test, but in looking at bars previously, she always seems to have more bars in the same location as me. My phone in our condo here is always around -111 to -120 (LTE). That is right on the cusp of bad from what I can tell. Not sure where to go from here. Really don't want to do a factory reset, but I've read it can help clear up problems like this. Not sure how. Might be a lemon, as I've only had the device since February.

i suggest you call your provider and ask them to reset your phone on their system.
It might cause a difference because of flushing out of any information that may have been related to issues on your account.

Hmmmm...not sure what this is or what it would do. Never heard of such a thing.
Just got another dropped call. Signal was about -114. I placed a call. While it was connecting, the signal went to about -130 and then to -102 and then dropped. On a second attempt, the signal went to -97 and it connected fine.

Normally when you call your provider to report a problem with your phone.
One of the things they do is to reset your account in case there is an issue in your file as well as doing other tests.
It is similar to you cleaning the cache on your phone from time to time as bits and piece of old files then to slow down your phone.

Try to swap the SIM cards and check what happens.

So this is an older thread, but the issue had been ongoing. Lots of things tried. New sim. Called Rogers (my provider here in Canada) and had them reset mobile connection settings on their end. Tried resetting on my end. Seemed to get better and then back to being an issue again.
Lately it had gotten worse. When I would drive home and park in our parking garage, I would immediately go into roaming mode and was no longer connected to the Rogers network. I was then connected to Rogers-EXT because I had enabled data roaming on my device, from a previous call to Rogers, it was their suggestion to try and keep connectivity, as it is included in my package. The phone would stay roaming as I rode the elevator and into my condo and then usually connect to WiFi and then eventually reconnect to the main Rogers network. Meanwhile this never happened on my wife's S7 Edge, going the same route from her vehicle. Same device, exact same settings, same software version, same updates, etc. Her's never entered roaming mode or got disconnected from the main Rogers network.
Lately, when mine had been entering roaming mode and after I entered my condo, it would stay connected to Rogers-EXT. No matter what I did, a reboot, turn roaming on and off, etc. I had to physically remove myself from the LTE network and then reconnect and register with the network, and then I would connect to the main Rogers network and stop roaming. This was all getting damn frustrating, especially since the same thing was not happening to my wife's phone.
One setting I had not read much about and had not tried was VoLTE. I went into settings and turned this off. I immediately started getting a bit better readings on signal strength as well as no roaming issues any longer at all. I could park, ride the elevator and get into my condo and stay connected to the main Rogers network without issue, exactly like my wife's phone. Funny thing is, VoLTE is ON, on my wife's phone.
I really have no idea why her's works and mine doesn't, other than a hardware issue on my device. I thought about sending my phone in, as I'm still under warranty until the end of December, but right now, everything is working as expected and I haven't heard call quality suffer at all, with the calls I've made so far. I really didn't want to have to wipe my device and send it in and deal with a loaner if I didn't have to. I only plan on keep the device until about August of next year anyway.
If anyone out there knows of why this was happening to my device and not hers or if you have any other suggestions as to how to fix this and re-enable VoLTE (although I don't think it's really that important), please let me know. Again, it sure seems like a hardware (antenna) issue to me.

Aaaaaaaaand nevermind. Worked fine for about 3 days and today it was roaming again after coming up from the parking garage. Ugh. Wish I knew for sure this was a hardware issue. Such a pain to send your phone in, use a loaner, set your phone all up again when you get it back.

lost cellular data

So, when I woke up this morning I noticed my cell signal strength icon was one I haven't seen before. I tried rebooting and toggling airplane mode. I also verified that my sim is working in another device. I attached a screen cap with the icon.

Noticed something similar with mine. I had to turn wifi off, restart to get LTE data (verizon) then turn wifi back on. If restarting with wifi on the LTE data doesn't register.

that didnt work for me
update: had to factory reset, looks like verizon doesnt like that essential ph1 wont take all their bloatware, etc. might have to return the phone if this keeps up

My data connection has also become very erratic - and I've lost voice+data (VoLTE connectivity) wholly yesterday. Worked fine with the activated SIM from my HTC 10 from the 31st to yesterday.. Now, not at all, I've not been able to restore it since.
Really don't want to return it, as I really like the phone, but this has nexus 5x issues written all over it for long term use...
Hoping essential can get a certification and an agreement with Verizon before my return window is over (or at all)..
Pretty disappointed in Verizon here.
Sent from my PH-1 using XDA Labs

Same here, another issue is that essential shipped my phone and within a day i had an email from essential saying that verizon certification is still in progress. verizon will probably not certify it with their system unless essential lets them install their monitoring crap all over the phone.

The Nexus 6P didn't have the bloat and worked fine.
My PH-1 works fine including Enhanced 4G LTE Mode.
What do you have selected for network type?
I have the first one selected because that's the only one that includes the various CDMA protocols, EVDO and LTE.
I see the same connectivity that I had with my Nexus 6P.

i have global selected, as it covers everything the phone can connect to. i had the first one selected but it wouldnt show the lte+, just regular lte. i also have Enhanced 4g lte mode on. it just happened to lose service earlier today. if it does it again, ill probably return it after a visit to vzw

I have the same settings as you, I had functional "enhanced 4G LTE" for the first 4 days as well... That ended yesterday morning abruptly, and I'm not able to bring it back.. There's more happening here.. How long has your device been on the Verizon network? Only a hunch - in a few days you won't have "enhanced 4G LTE" either, even though it'll still be checked, and provisioned for it.

Cellular network is not available
After 7 days my phone won’t make calls I can only use data I’m on sprint and it was working fine until today I call sprint they had no answers at all I email essential no answer now I can only use WiFi calling while home and axx out at work

So, upon further digging I found a place to look at some more in-depth stuff relating to signal stuff. I did some fooling around and switched it from unknown to lte/cdma/umts auto (prl) and it seemed to work after a few moments of time. Though it seems have gone back to t he unknown state again but is working normally for me now, so maybe it was changing states and then a reboot?
How I got to this screen was by punching *#*#4636#*#* into the dialer, and went to phone info

I'm having a similar issue. I often lose my signal. I will have the full triangle/bars but no label of the signal(LTE+/LTE/3G/1x/etc....) and no cellular data at all.
The only way I can get it to return is to restart the device. Happens a few times a day, can't be 100% sure why, but it often appears to be when switching from WiFi -> Cellular only.
I have Verizon, I have had a Nexus 6 and then a Pixel XL for the past 3 years, never once had this issue.

I had constant disconnects and lost of service with my Tmo sim. Tried my Xfinity (VZW) sim and it was great until this morning. Complete lost of service. Airplaned mode on and off, connected to old school RTT 1x.... lol This phone's cellular just plain suck for a lot of us regardless of carrier. Not sure if we just have bad phones because apparently there are those who claim they have great service and connection.

I'm having this problem with Verizon. Seems like if I'm on wifi for a long period it only connects to 1x and putting in airplane mode and stuff won't get it to re-connect to to LTE. Only a reboot seems to fix the problem.

Necro post here but chiming in that I have the same problem with Verizon LTE. Happens when I'm moving long distances in car too. Suddenly just drops LTE and only a reboot will bring it back.

You might check out my post from the Oreo Beta thread... I was having some goofy signal issues early on which I've pretty much cleared up by doing what I mentioned here. Someone touched on it briefly earlier but only mentioned monkeying around with the settings, said nothing about picking up a new PRL.
I state this in that post too, but just in case: I offer this with no express intent of warranty, if you screw up your device, it's on you.

I just changed it from global to LTE/WCDMA and I got LTE back almost immediately. Was weird and global had been working for me for awhile now so not sure what happened in the past few days...

I had, right after writing this, tried *#*#4636#*#*
I set it to global as instructed in another post. The next time I drive a distance in the car I'll have to see if I have the same issue that only a reboot would fix again.
Thanks

I had the same issue and I resolved it a little differently than the previous posters. I turned on adb debugging and logged into adb shell and user-disabled com.redbend.app. This stops the Sprint oma-dm service from running. After doing this I no longer have the issue of my device not reinitializing lte after sleep or 3g.

I have essential on vzw but my only issue is my device won't connect to 4G. If I change network to LTE I get full 4G service but I'm unable to make phone calls. Went into vzw store and they told me you didn't get the phone from us so we cant help you. Day 14 fml

On Xfinity mobile, I had similar issues. Great LTE but sometimes calls just don't work at all. I mess with various settings and it'll work for a bit then so again. Gave up and ported over to Sprint for the free unlimited year which is still probably not worth it. Should've kept with Xfinity Mobile. Lol
