3G not working on Nexus 5 - Nexus 5 Q&A, Help & Troubleshooting

I've been using my 3G mobile connection for quite a while now.
Well, WAS using, someday, it suddenly stopped working. I thought it was because I exceeded my 250mb limit but, unfortunately, it wasn't that.
It usually showed up 'H' and had a fairly nice download speed, but now it only shows E and has a tremendously bad download speed.
So, after figuring out it wasn't my plan having its limit exceeded, I decided to try somethings to fix it. At the time I was using the most recent CM11 nightly.
I did a wipe and installed the latest snapshot. Didn't work.
I tried configuring the APN, exactly like my parent's Moto G, and had no luck.
And then now, as a last resort, did a COMPLETE wipe(including internal storage), and flashed the latest Android L ROM available.
Nothing worked, at all, actually.
I've also tried inserting my SIM card to my mother's Lumia 720. It worked as it should. Showed up 'H'. Her functioning SIM card also didn't work on my cellphone.
I'm getting desperate.
I live in Brazil, and my mobile operator is "Oi"

call your operator. you are getting edge, "E". thats very slow data speeds! also, look in tbe main settings, mobile networks. what is it set for.. lte, 3G, or 2G?

As I said, the SIM card works properly on another cellphone, and other SIM cards don't work on mine. The network is set for 4G.
The problem is on the cellphone, that's for sure. I ran out of ideas so I decided to post here.

try this.. dial *#*#4636#*#*, then press phone info, then change the lte/gsm to wcdma preferred. this will prefer 3G(not lte). btw, have you tried calling your operator? it can just be how they have you set up in their system now.

I did call my operator, but they told me to try the SIM card on another phone to see if it works and it worked. They didn't have anything to do.
Also, I've tried configuring that, still shows E. If I choose "Only WCDMA", my network goes unavailable.

did you try the *#*#4636#*#*?
if its fine with the other sim card, then its not your phone. you might need a new sim card.

I tried the SIM card on ANOTHER phone, the one I'm using on my phone, on another one. It worked.

dont know what to tell you, honestly. you tried another sim card in your phone, and it works. you tried your sim card in another phone, and it works. but your sim card doesnt work properly in your phone.. it should be working in your phone as well then, unless you do not have a 3G signal around you. personally, id just ask them for a new sim card, just in case.

No no, I tried another SIM card on my phone and it didn't work. It's all about the phone, not the sim card.

oh, ok. the sim reader could have broken(somehow). thats actually a fairly common issue. can you get an exchange? where did you buy yours?

I bought it from the internet. I don't think I can get an exchange.

UPDATE:
I've figured out the problem. It's the signal. When the H signal isn't strong enough, it goes to E. I was on another place on my city today and there H was working, and exactly when I got back, the signal started being EDGE.
Now, I've tried flashing another radio. I just downloaded the ZIP and flashed. Note that I am on Android L. It still has the same problem. Now I ask, how may I fix this?

UK SIM not working even though phone is Unlocked

Ok so I am in the UK right now for the summer. Before I left I unlocked my phone and when I got here I went and bought a pay as you go 3 SIM card since they offer all you can use data and all.
The guy at the store said to wait 20 min then call 444 to register the card. After 20 minutes or so I still had no signal on my phone. I went into settings > Wireless > Mobile > Select network and selected 3 but it said "this SIM card could not be registered on this network." Same thing if I selected automatically. So I decided to try a friends Vodaphone pay as you go card in my phone. The Vodaphone card works perfect, I can make calls, send sms, etc.
So I went back to the store the next day to see what they say. The employee put the SIM in her phone and it worked perfect, which means that there is something wrong with my phone.
I went back and decided to unroot then reroot and unlock. After encountering multiple problems with that I have finally gotten back to root and unlock but the 3 SIM card still does not work while the Vodaphone one does.
Is there anything I can do from here to get the 3 SIM to work?
What rom are you using?
sorry forgot to mention that. Right now I am on the stock rom and stock radio. I tried flashing another radio and using the SIM card on Leedroid and RCmix HD and nether of those worked.

Have you tried the 3 SIM in a different phone perchance? It seems like the unlock and the Inspire are working as the Vodafone SIM worked.
I agree, maybe there's something different about that sim that the Inspire can't read it.

Yes I took it back into the store to see what they would say/try to get a refund. They store employee put it into her phone and one of her coworker's phones and the it worked fine in their phones. I do know exactly what kind of phones they had since they were for sure Euro only models that I have never seen before but one of them was a Samsung with a touch screen and keyboard, much like a blackberry. Not really relevant to this, I think.
They would not give me a refund since it work in their phones. Which is why I am here stuck with a 3 SIM card and looking for help to get it fixed
Well that at least establishes where the problem is. When you boot the phone with the 3 SIM, does it give a "no sim" error, no signal at all , or no data access(voice/999 still work)?
When I first put in the sim it gives me a popup saying "Unable to detect your SIM card. Please make sure that your SIM card is properly inserted and restart the phone." It gives two options, Shut phone down and Restart. It also says this when I put the Vodaphone card back into the phone. I just have to restart the phone and I will have signal when I have the Vodaphone card in.
So I click restart. After it reboots, I have no signal (grayed out bars with a small 'x' above them). In my notification tray I have 2 new notifications. One saying that my SIM card has changed and another saying there is a sign in error to my gmail account.
If I click on the "SIM car changed" notification it gives me a pop up saying "You have insterted a new SIM card. Your phone will change the following settings according to your SIM card: bookmarks, shortcuts, wallpapers, ringtones, language selections, and input settings. Are you sure you want to replaces these settings on your phone?" Then it gives me 3 options, "Yes" "No, later" and "No."
I do not get any other notifications or error messages after a restart.
Backup your ROM then try flashing cm7 and see what happens, with the 3 SIM in the phone.

Ok I wiped everything and installed nightly #77 with the 3 SIM card in the phone the whole time. It has been 2 hours and I have not taken out the card yet and it is still not receiving service. So I have no idea where to go from here.
If there is nothing else I guess I will just have to suck it up and go spend some more pounds and get a Vodaphone card for myself.
Thanks for the help and if there is anything else you can think of for me to try please, I am open to all suggestions!

If they won't swap it out for you than I would say that is the best bet. I know for a fact that cm7 supports 3. There has to be some other factor affecting it. Did you have the 3 guys try their SIM cards in your phone?
Sent from my HTC Inspire 4G using XDA Premium App
No they did not, that is the only thing. They never put their card into my phone.
*sigh* I was really hoping for unlimited data because that would have been soooo helpful to be able to use maps while wandering the city. I guess this just was not meant to be.
Thank you so much for all the help! I really appreciate it!

[Q] Xoom 3g sim card problem

Wondering if anyone can help, im using team Eos European 3g rom zoom. now i tried 1 sim card and the 3g works perfectly but when i try my other sim, i enter the pin code on screen , it accepts it, then immediately says "Sim card removed, the mobile network will be unavailable until you restart...." .
The sim card definitely isnt broken because it works in my phone and 3g modem on my pc. I've tried restarting the xoom with Wifi off and no luck.
Thanks

how old is that "other" sim card? Reason I'm asking is that sim cards use different voltages and old cards tend to cause problems in modern devices.
Around here, providers usually swap sims for free if you say that you've got a problem with one, so I'd go for an exchange if your sim is older that maybe two years...

Its actually brand new, got it on the weekend. It works perfectly everywhere else. I think i'll go to the provider anyway today and see if i can try a sim swap.
This really is baffling me now. I went back to the providers store and tried a different one of their sim cards and it doesnt work either. I just cant understand why my xoom can read certain providers sim cards and not others? (Its definitely not network locked). Could it possibly be the type of sim card (as in a 32k vs 64k etc)?
Any help would be greatly appreciated

T-Mobile not working with OPO

Hey everyone thanks for your help in advance... I just bought my phone and went to T-Mobile to get a new micro Sims card. After putting it in, the phone didn't recognize it. I put in the APN settings and it doesn't save it. This really sucks right now because I don't know what else to do. Any help will be greatly appreciated. And my phone isnt rooted yet, just want the stock for now. Thanks again
Is the sim activated? Sometimes on a new sim it takes a few hours to start working.
I was already on Tmo with an N5. I just moved the sim over and all was good.

What he said. If OP has another phone that uses a MicroSIM, put the sim in that phone and see if it works.
Also did u insert the sim properly into its slot?

I screwed up and instead of using my old Sim card and cutting I went into T-Mobile and had them activate a new micro Sim card and put it straight in. The old one is deactivated.
The new micro Sim does work in my old gslaxy S2 phone which used an older big Sim card. Its now using a Sim adapter.

Did you insert the SIM card in the right direction and not upside down? I know thats silly to ask.
to be honest its simple man and actually nothing you needed to make a thread about. Simple go to TMobile store and try an already active sim card. Go to AT&T and see if they can put an active sim card to help you out. Basically go to anywhere that works with a TMobile or AT&T derivative and try it out. Nothing really else we can do to help you on this.
Not try to be rude or anything but its the truth. If none of that works then you may have to RMA. Also maybe find a friend or family member and try their sim . Good luck :good:
Should work. Using my one plus with Solavei (t-mobile based company) and having no issues.

First time i've also put the tray wrong. True story
Just had this problem after coming from using the phone overseas and no signal whatsoever on the phone despite numerous restarts, SIM cleaning, and chats with T mobile. After verifying the APN was correct I went to Settings-->About Phone-->Status-->SIM Status and checked to see if the SIM was connected(it showed my phone number, but was disconnected). So from here went to Settings-->Mobile Networks-->Network Operators and let the phone find carriers automatically. Mine showed T-mobile(with a little SIM icon to the right of it), Verizon, and ATT. I clicked on T-Mobile and it registered and is now working.
Probably saved me $15 at the T-Mobile store. Hope this helps even just one of you.

Mobile data stopped working, APN is correct.

So just randomly yesterday the mobile data on my Honor 6x just cut out. I am just getting the service signal bars, no 3G, 4G icon. I've tried resetting APN and formatting the phone back to original spec, but I still have the same problem. I also ejected the SIM and reset it just for a shot, but nothing.
I am using a T-Mobile MVNO called TAG Mobile if it makes a difference. I can make calls and text fine, and wifi works as well. Just the mobile data acts like I have it turned off. I've checked to make sure all toggles are switched on for 4G but to no avail.
Oh and I am running Nougat 7.0 emui 5. I've been using it for a couple months with no issues till now.
Can you try another SIM card?! Just to know if the issue is from the phone
I don't have one available right now, but I will try to get a replacement SIM sent out to me. I don't really have anybody near that would let me borrow their SIM either.
Ok, once you do it, let me know the results
Weird, the network came back up randomly. Didn't even need to try a different SIM card. Thanks

Problems with customized device and Sprint

I flashed the crDroid ROM onto my stock g7 Power, no problems. Flashed gApps and Magisk, everything ok. I did all of this while the device was unactivated and with the SIM card not in it. Everything works fine. But when I activated the device on the Sprint network and inserted the SIM card, I get no data. I know people have said you can manually edit the APNs in the Mobile Network settings, but the problem for me is, there is no APN option in that menu. However, when I remove the SIM card, I DO see the APN settings option there, but of course the whole menu is grayed out because the SIM card is removed. Has anyone else been able to customize and root one of these phones for use on the US Sprint network? Should I use a different ROM? Any suggestions would be helpful.

Hey there... This is just a possibility...
A while back, I put my sister's CDMA sim into a custom Rom-ed phone. Couldn't add an APN for the life of me. And then, duh , it turns out it was because the phone radio was set on LTE/UMTS (auto)... Is your radio set for LTE/CDMA?

Turns out it was on "LTE/CDMA/UMTS auto (PRL)". I changed it to "LTE/CDMA auto (PRL)" which is what the Sprint network uses, I'm pretty sure. That did seem to change some things, but I still don't see any APN settings and I still don't have data, unfortunately.* I think this ROM is just not set up to work on the Sprint network? Maybe I'll try flashing a different one.

Did you ever get it going? When I install Pixel Experience + I have no apns at all. Not in system/product/etc or product/etc which is where they are supposed to be located. So I just paste apn.conf.xml in the system/product/etc and set 0644 then go to networks and internet/mobile networks/access point names and hit reset to default and data's on , reboot afterwards and it's all fine. What's your model # on your device? Also are you sure your sim card isn't damaged? When they crack sometimes it's impossible to see with the naked eye. And technically you're not on Sprint anymore you're on T-Mobile because they finally finished the deal and Tmo now owns Sprint. (Which is a really good thing imo) ;p if and when you do get your issue resolved be sure and save your apn.conf.xml and upload it to Google drive or something so you'll have it if you need it again. I noticed that the first APN xml files I linked you to I had apn.config.xml for the name and that's not correct supposed to be apn.conf.xml My bad on that. Sometimes I drink a lot of coffee.

Please tell me more about CDMA also using GSM because they are two different technologies.. CDMA was used by USA military back in ww2 to send messages safely and GSM is what most the world uses. CDMA has always been more of a USA tech while GSM has always been pretty much what everyone else uses. They both send information in different ways. They do not work the same or together far as I know.
If you want to be more compatible with development use a GSM carrier like Metro, T-Mobile because GSM is what still rules the world far as phone tech goes. And we here in the USA only make up a small piece of the world far as development goes.
