Problem roaming

Good evening all,
Hopefully someone can answer my question.
Sunday I took a road trip. I noticed that my phone had no service. In the past when I left the t-mobile area my g1 would automatically connect to whatever network was available and the roam indicator would show up.
I tried to manually connect to at&t through the network operators menu. My phone said "Your sim card does not allow a connection to this network.".
I have a rooted g1 running the official t-mobile 1.6 rom. Is this a problem with my rom or my phone or the network. I've tried searching and I haven't found much of a solution yet.
I am in the usa. A lot of the google search results I got were from Europe.

might not have been a ROM issue; just a bug...
Did you reboot or force radio off then back on?

I have the same problem and yet no luck to resolve this.

I did reboot and enable/disable airplane mode.
Today I switched to the Cyanogen Rom. I'll see if that fixes the problem. I tried to manually switch to at&t, but it still says that the sim card does not allow that. I am in the t-mobile coverage area; t-mobile probably does not allow the use of a different network when their network is available. I'd like to test it out to see if roaming works now, but I'm not taking a drive out to the countryside just to see how my phone works.
I guess this one might be hard for me to test because I am rarely out the the t-mobile coverage area.

No evdo connectivity only 1x

Downgraded to calkulins v1.7 since i was having issues with 1.8 and now i am not getting evdo connectivity at all. My phone only connects to 1x. Ive tried restoring my settings when i do ##3282# edit data profile and evdo. Im not sure what else to do. Ive flashed 3 different roms and nothing helped. What else can i do?

Go to settings, wireless & networks, mobile networks, mode of operation, and chose evdo only. This fixed my problem, hopefully it will help you.

I have no option to select mode of operation. I am unrooted now and back on bone stock ROM and still have this issue so I am not sure what is wrong. I am currently chatting with sprint to reset anything on their end. However, it still only connects to 1XRTT

try flashing 1.8 back and change the operation mode to hybrid. double check with ##3282# to also make sure the evdo setting is on automatic.

i just fixed this problem myself. go back to calkulin's evio 1.8, and change setting to hybrid. to see if it works, type ##3282# into dialer and choose view mode. go to evdo settings, and make sure its set on automatic. if not, then:
retrieve your msl (free app in market msl reader) and type the same code in, but choose edit mode. type in your msl, and go to evdo settings, and change to auto.

Ahhhh! I don't have this option :/

flash back to calkulin's evio 1.8

Changing to EVDO only helps with 1X, but I found out that the setting to EVDO only will not allow incoming text or calls. I had to put it back to Automatic.

I've tried everything everyone has posted so far. Changing to EVDO only and automatic and all that stuff. I took it into the Sprint store today and they tried telling me it was on 3G since the icon was showing that. I told them the evo icon never changes to 1x even when connected to 1x. She still didn't believe me. So I downloaded a few apps that showed my phone only connected to 1x and she downloaded the same app and it showed hers connected to EVDO. She said she couldn't trust the app and then she compared my phone internet load times to hers and mine was actually faster so she still wasn't convinced. I explained that the 3G is on a higher frequency than 1x and being indoors she may have a poor signal compared to mine. Also I told her that everyone in our area is probably connected to EVDO, thus slowing it down, versus just me on 1x, so I had better speeds. She said that is very true, so she ordered me a new Evo that should be here in a few days.

THIS WILL GET YOU 3G
but you will be constantly roaming
try it out and let me know if it works for you.
##775#
search for 00001.prl and change it.
commit changes and it will restart
give it about 10 mins to get connected right and do a speed test.
i was getting only 15-20 kbps using the latest sprint prl.
i changed to this modified prl and im getting 1700-2200 kbps
i think sprints prl's are messed up..

What test can o perform to prove that its versions network I am using after this hack? An iplookup says I'm still connected to sprint.

Not longer seeing telus

Hi All,
Not quite sure what happened here.. Upgraded to latest nscollab yesterday, everything was working fine. Decided to try the "Antennas" app to see if it'd show where the towers are near me, switched to 2g mode, played around with it a bit, switched off 2g mode and now my phone does not see telus at all. When I go into search networks, telus simply doesn't show up and my phone stays in emergency mode.
It sees rogers fine and is able to connect to rogers with a friend's rogers sim. I've tried my telus im in other phones and it works fine, other people's telus sims in my phone don't work either.
I've tried reverting to an earlier backup as well as going back to a stock backup. I've also tried reflashing both the kb1 and kb3 radios, no luck.
Anyone know what might be the issue here?

both Telus / Bell do not have 2G
they only have 3G, as in the VOICE only works via 3G
it was the same using the SGS i9000

Did the rogers SIM work on 2G (Edge) only? I am guessing Rogers and Fido will work, but only on 2G
Same happened to me, on Fido, my phone could no longer connect to 3G...Only 2G after playing with settings. I returned the phone
The reason why Telus-Bell SIM would not work at all at this point is that they only support 3G...

That makes sense, but i don't have it set to 2g mode anymore. It should be seeing 3g just fine.

Just tried that, nothing. I think that's the same as a wipe data in recovery?
I've tried:
- Reverting back to a stock backup
- Reverting to an earlier working backup
- Doing a factory reset on both of the above
- Reflashing the radio on both

This just happened to me, I switched to 2G and got nothing but com.android.phone quit errors, now I can't get back on 3G. Flashed radios, data wipe, everything... wtf... it's back to stock now and still can't get on Telus... double wtf...

Christ... finally got it... my head hurts from all this reading
For some reason it was on the wrong band. Do this in dialer... *#*#4636#*#*, phone information, menu, select radio-band, USA, and should work make sure its on WCDMA preferred as well under phone information

I had the same issue when in Canada, and forgot I had the band set to Europe (my region).
I set it to Automatic detect, i know catching signal will take longer. But then I dont forget

i had the same problem since may 14th (sat), thanks for the fix!!!!!!!

Same thing happened here, same solution. Glad you stumbled on it too!
As the title says, had the same problem on my Nexus S (running on Bell), I believe manually switching the 2g/3g toggle in cyanogenmod rom accidentally is what set it off.
Glad you found the solution!! Was maddening for me; knew there must be a way to fix through the UI, but until I fond it, phone was a wifi mp3 player :/

How to force LTE/GSM/CDMA auto (PRL) or any other Preferred Network Type.

Hello, I have no problem receiving an LTE signal on BCE (Canada) through the Phone Info Menu. I can select any of the preferred network types including LTE, LTE/GSM, CDMA, LTE/GSM/CDMA but it won't stay. Every day I have to go back into the menu and it reverts back to the first selection "WCDMA".
Does anyone know how to force this so it stays on LTE/GSM/CDMA. So it will stay on the LTE-enabled network unless there is a loss of signal and it reverts back to HSPA? It does this automatically when "LTE/GSM/CDMA is selected, but again reverts to CDMA within a day usually.
I did some searches here, but 99% of what comes up is just people asking how to enable LTE or if their network gets it?
Any ideas? Maybe some sort of macro thing.
Regards.

Add this line in build prob
telephony.lteOnGsmDevice=1
Save
Reboot
Now in settings/more/mobile networks u will have an option to choose and it will stick. U have to add the line every time u flash ROMs.
But I keep iron WC DMA/gsm for better battery speed is OK on h+

Thanks for the helpful reply man. I haven't edited a build.prop yet, so Ill have to check it out.

Alright thats all done now, works like a charm. Like that I have the option now either way. I typically stick to WCDMA/GSM when on the road or at work where LTE is spotty, but on days off for around town I would rather just be on LTE as I usually just looking up something quick when Im shopping or something.
Thanks again.

Nice
I keep it at LTE, it does have less bars but quality is same for me, speeds are amazing. Also 4G is only data, not voice, so when u have an active call it will change to 3G.(but that's not the phone it's the network)
don't forget to do it again if you flash new ROM, also Tethering WiFi won;t work, there is a fix but it's complected for me, so I just go to W/G if I need to share connection.

So, my Nexus 4 shipped today, and it'll be in my grubby little hands by tomorrow evening. I, unfortunately, can't activate it until March, as I have to wait for my Verizon contract to end, but I keep seeing this LTE stuff, with no real explanation. I do know that the Nexus 4 has an inactive LTE radio in it, but what's the use of activating it, if T-Mobile doesn't have LTE? Is this only for the AT&T users?

There are other threads dealing with who can access LTE in the USA. I am in Canada and on Bell.

I'm in Canada, using Fido. I activate the LTE on my Nexus 4. It works fine, but I'm not able to share internet with wifi hotspot.
I have Android 4.2.1 (latest OTA from Google).
There is a bug with this version or it's only because I activate LTE manually ?

As per the previous comment:

what is the fix to get hotspot internet sharing with the Nexus 4 ? Do i have to had a APn for 3G and swith that it to share my connection ?
I'm with the original firmware. Android 4.2.1

process com.android,phone hase stopped working
i recently got a rom from revolt on my n4 and i switched cdma to lte gsm wcdma auto
i also went into build.prop and wrote down telephony.lteOnGsmDevice=1. i went and to setting, more, mobile networks chose the correct setting. so now i got 4G. great i can make calls. GREAT. but i cannot receive calls...
need help with this. im really choked about this ROM

Even if I select "LTE/CDMA" in the Mobile network settings menu. The settings page keeps displaying "CDMA preferred".
Does this mean it didn't work? In quick settings, I see my mobile data connection as 3G Bell.
LTE only seems to work when using the *#*#4636*#*# trick in the Phone app.

Thanks, but LTE doesn't work in my country, its always stick on lte/gsm/wcdma but it doesnt detect my gsm so i have to manually set it on GSM only but wont stick here every time i restart my phone i have manually set it on GSM only otherwise it wont detect my network
Any advice ?

How can I make "WCDMA Only" the default selection?
Where I Iive there is no LTE and the coverage of the service is quite poor, so the phone keeps jumping between E and 3G/H. I have to manually go into the phone app and select "WCDMA Only" is there a build prop tweak to make the "WCDMA Only" the default option instead of "WCDMA Preferred"?
Thank you.

So is there a way to get the nexus 4 to work on Verizon ??

Aah Crap ! Well thanks man saved me from buying on guess i will have to stick with my rezound for now then

fixed it
For everyone still searching for a solution to this problem, this worked for me. Go to phone information and turn your radio off. Then switch to LTE/GSM/CDMA then power down, DO NOT TURN YOUR RADIO BACK ON. Now remove your Sim card, put it back in, reboot and you should be good to go. DO NOT HGO BACK INTO PHONE INFORMATION OR ELSE IT WILL NOT STAY
If it still isn't connecting try fiddling around with your APN settings.

[Q] Nexus 4 Radio - No 3G/HSPA Signal

I've not had a 3G/HSPA signal on my N4 for a while now. Trouble is I don't know exactly when it happened as I'm generally on either WiFi at home or at work, where I know I can only get Edge.
I've tried the usual check the APN, *#*#4636#*#* and nothing's jumping out at me (if I tell it to use WCDMA only I get no signal at all).
I'm wondering if it was the 4.2.2 udpate and wonder if I've got the wrong radio - so the question is does anyone know what radio I should have on my N4? I'm in the UK on Vodafone, but I got the phone from the Play Store.
I've tried searching but the N4 seems to have had so many signal issues it's difficult to sift out the relevant stuff
I'm not rooted but I'm happy to do it if needed. Already tried a factory reset so nothing to lose!
Cheers,
Dave

have you tried a different sim card? thete isnt a specific radio per region, so thats not a problem.

Yeah, sorry, forgot to say. I tried the wife's SIM (different operator) and same issue, only got a 2G signal.
I was thinking it might have been an issue when they updated it to remove the LTE "feature"

Even i have the same problem . I am from India and also have tried a couple of sim card . Im not able to get 3g signal at all . Anyone pls help....

i have the same issue solved whit RMA my first nexus 4 was defective, my new nexus 4 changed in warranty now works well
3G/HSPA networks

participles ipntsly
I started having the same issue today in Atlanta. Had another T-Mobile HSPA phone sitting next to mine with 4 bars while I was on Edge. My N4 is < 1 week old and seemed to be OK but now I can't get it on anything other than Edge.
I've checked my APN settings, reset the radio, turned data on/off and reset the phone with no luck.
Any advice?

Update: Just got mine working, here is what I did.
Wasted 20 mins talking to Google and T-Mobile. (I don't recommend this step.)
Type in *#*#4636#*#*
Scroll down and change 'WCDMA Preferred' to 'WCDMA Only'. At this point my bars switched from Edge to HSPA.
Now, undo the change and put it back on WCDMA Preferred. Make sure it still has a 3G or an H next to your bars.
Exit and enjoy the fast phone.

This worked for me.. thanks

I am having the exact same problem as Dave. My n4 has just stopped connecting to WCDMA (H).
I have tried re entering my APN's, Turning on/off mobile network, Airplane mode, rebooting and removing the SIM. From the test menu I have tried WCDMA only but I lose my signal completely and go to emergency calls only. If I use either GSM only or WCDMA preferred I can get a 2G connection but nothing more and when on WCDMA preferred it can lose connection completely as well.
I am also with Vodafone UK.

Getting bars on 'GSM only'
I have got the same issue on my Nexus 4, and I still don't understand how it happened in the first place. I updated a bunch of apps before going to bed and remember waking up to no signals on my phone.
Currently I only receive signal when I go *#*#4636#*#* and set it to 'GSM only'. Any other configuration (WCDMA preferred, WCDMA only, etc) results in loss of signal.
I have tried the following with no luck:
1) Restored Factory Settings
2) Installed an older version of android
3) Flashed multiple radios
4) Steps listed on this thread
Can anyone help me out with this?
Thanks
