Can't use Lte, 4.5G - Nexus 5 Q&A, Help & Troubleshooting

Hi guys,
I bought a secondhand Nexus 5 last year and I'm using she gladly since then.
But I can't get lte and 4.5G with my phone.
When I call my carrier and ask about it they say because of the imei of my phone is changed, they can't give my phone this service.
Is there any workaround for this situation?
Thanks in advance

Try making them think you've got new phone

My imei and the imei on the back cover is not the same.

I have swapped parts on broken phones so the imei on the back cover never matches the imei in the phone.
Does the phone have a generic imei? Did you check to see if the imei in the phone has been blacklisted?
I wonder how the carrier knows the imei has been changed.

They say In their system my phone's imei belongs to an old Motorola phone, and because of that they say they can't give me 4.5G signal, saying that phone doesn't support. Imei is not blacklisted in my country but not recorded.

Insert your simcard to a friend's phone or something, then activate 4G, then insert your sim card back to N5.

Not much you can do since the nexus 5 imei has been changed to a Motorola imei.

Check the IMEI stamped on the SIM tray. It should at least match in Settings, About phone, Status, IMEI information.

Default phone number - any way to change it?

I got my Nexus 5 on contract from Three Ireland and I had to get a new SIM card with it and transfer my existing number onto that SIM card, but for the half a day before the transfer the new SIM card had a different phone number assigned to it, which appears to be what the device thinks is its phone number, even now that my existing phone number is in use. For example Hangouts just randomly asked me to confirm my phone number again, but it quoted the new SIM's original phone number instead of my existing one. Any idea if this is stored somewhere on the phone or is the SIM card itself reporting the wrong number?
Did more digging and found the wrong number is also being displayed in Settings > About Phone > Status > My Phone Number
Its written to the SIM itself. There used to be apps that could rewrite it. Certain custom roms too... or just other model (non-android) phones

Ah okay thanks, I think I have some old non-smart phones lying around that might be able to change it :good:
I'm in the same situation but it doesn't really bother me. I've only had to confirm my number a couple of times. Maybe 3 would send a replacement sim if you asked them. That should have the correct number on it.

Yeah it should. Its purely cosmetic though

3 told me that they couldn't change the number on a single and would have to send one out, which they did in 24hours with my number on it. No problem.

You can't just switch back and forth at will? In Canada here....can pop my sim into any unlocked phone anytime.

I'm pretty sure you can just switch back and forth by switching the SIM. I'm on AT&T and I can do that, and I don't see why you wouldn't be able to on Sprint.
It doesnt seem to work with sprint
Sent from my LG-LS980 using Tapatalk
it wont work with sprint because its cdma and also i dont believe you can do that, with your imei i think they have on record that its a nexus 5, well im almost sure with the imei they can identify your phone, that is unless you somehow changed you imei but i think any modification of imei is not allowed on xda not sure either way i dont know anything about it

[Q] Nexus 5 carrier locked?

Whats up guys, I'm facing one hell of a dilemma. I purchased a Nexus 5 from craigslist. The person said it was bought from Google. None the less I did a IMEI check on Swappa when I bought it and it came out clean. The person was using it on T-Mobile pre-paid so I went with the hunch that it was not bought on the JUMP program. Unfortunately, at that time they didn't have their sim in the phone so I could see it working on T-Mobile.
Since, I'm on Verizon I couldn't test the phone out in person. The phone is for my mom who is on AT&T. When I popped her SIM in the phone was showing "No Service", despite having the correct AT&T APN. I googled and googled and noticed people were saying the battery cover could affect it. Well this phone has a loose battery on the right side (when looking at the phone with the screen up) so I pushed on the battery cover and still "No Service". Lastly, I flashed the factory images from Google. When the phone booted back up it was still saying "No Service" but then showed empty/gray bars and detected it was on AT&T. Every now and then I might get one blip of white inside the bars, but then it immediately goes back to empty gray bars or "no service". I can't make or receive calls from the phone. Let's not even talk about cellular data.
I called Google, low and behold the phone wasn't purchased from them. Then I called LG and LG said its a T-Mobile phone. By chance do you guys know if T-Mobile sim locks the Nexus 5 when you're making payments? I can't figure out if this phone has bad radios or it has some lock in place by T-Mobile. Is "No Service" or empty gray bars a symptom of carrier lock?
TL;DR: Does T-Mobile sim lock the Nexus 5 when you finance the device from them?

My first suggestion would be to check if the phone is blacklisted from this website http://checkesnfree.com/

Wait the N5 doesn't have a removable battery, or a cover that comes off. How'd you push it in?
Anyways, I purchased my N5 from T-Mobile directly. After some issues with service in my area I went to an ATT store and asked if I could use it on their network. The rep at the store said yes, it would work, but since they don't actually carry the phone I could not insure it with them. She seemed very confident it wasn't carrier locked which is what I've heard all around. I can't confirm that though, I stayed with T-Mobile.
P.S. Questions belong in the Q+A section, not general.
I don't think Verizon have approved the n5 for their network. Try a SIM from another operator or call Verizon to confirm.

the n5 from tmobile is not carrier locked. no nexus 5 are carrier locked. i have had an att sim in my tmobile bought n5, and phone/data signal worked fine.

Did you even read the thread? He said he couldn't test because he has Verizon. N5 doesn't operate on Verizon. He was asking about ATT... He tried an ATT SIM already and it didn't work.
Sorry I'll assume the op hasn't been scammed.
Does the phone display an imei and baseband in the about phone section of settings?
Sent from my Nexus 5 using Tapatalk
Guys, I understand it's a unlocked phone. I just want to know if T-Mobile puts a lock on the phone when you finance from them.
Yes, the imei is in the settings and yes its clean.
Not a smart move, buying a phone from somebody on craigslist without checking to see if it works. No receipt, didn't check to see if it was blacklisted, and it has a loose back cover...Could have faulty hardware, might have water damage, might be blacklisted...lesson learned. Good luck.

No, they don't. They can blacklist the imei by which you won't be able to use a T-mobile sim. But they can't carrier lock the device.

Thanks Vin, then I assume it's a hardware issue. If anyone wants to buy this N5 PM me I just want to cut my losses.

No doubt about that, but I have bought numerous phones from Craigslist, Always for Verizon though. This was my first venture into the GSM realm.
Already checked the moisture sensor in the sim tray and it's white. Like I said earlier I checked the imei at the time of purchase and that was clean as well. My mistake was not having a GSM sim and thus not testing the device

Just a thought but it's best you take it out of the equation first.. Have you checked in settings-about and see whether the IMEI is showing up?
Have you tried flashing the different radios and see whether it helps??

Nexus 5 has "No service"

I got this phone yesterday. It is currently running Android 6.0.1 and the status bar keeps saying "No service". I have tried using 5.1.1, as well - same message.
When I first got the phone, I tried rooting 6.0.1 with the latest SuperSU but resulted in a bootloop so I reset the phone + unrooted it with the Nexus Root Toolkit.
I have tried using my SIM on another person's phone - works perfectly.
I have tried using another person's SIM on my phone - "No service".
In the "About phone" section -> Status -> SIM status, the phone recognizes my phone number and IMEI number. So my phone knows there is a SIM there and everything, it just can't connect to the phone network for some reason.
What could possibly be the problem?
Has the imei been blacklisted? Have you tried searching for networks?
i been getting the same thing on and off since i had mine and seem stuck as well
What network are you using?? If its CDMA you have to get the imie# activated into the system by your wireless provider... So any Verizon/sprint for example you need to get that activated in their system.. Only GSM is plug & play at&t/t mobile

I am using Bell. It is HSPA I think. The SIM card works with my Oneplus One, which hasn't had its IMEI # activated on their system.
I've decided to just return it and get a new one.

Hspa is a GSM technology.. Make 100% sure the nexus supports your radio bands.. I would honestly either try a nother sim card or call customer service.. Perhaps it could be a defective unit. Also make sure it fits 100% in the sim tray. I had that issue once with a sim that didn't quite snap into the sim tray

I just checked and Bell requires phones to be 850 or 1900 MHz compatible. The Nexus 5 supports these frequencies. I tried my sister's and friend's sim cards and it still doesn't work.

Also get a can of electronics spray air.. Blow out the sim port. Don't use your mouth as saliva can corrode the connector and they can claim water damage

Can't network unlock Nexus 5 (UK)?

Hello,
I've just bought an used Nexus 5 off eBay (UK). Seller mentioned it was network locked to BT mobile.
When I insert my giffgaff SIM card I get Emergency calls only and no signal. I was about to buy an unlock code but I can't seem to find a way to display the prompt to enter the unlock code.
I've tried the methods described here: http://m.sim-unlock.net/simlock/LG/Nexus_5/ but I simply don't get any prompt.
What can I do to network unlock my Nexus 5?
Thanks!

Honestly man, I've never seen a "network locked" nexus, root it and flash a custom rom, if u still get no signal, then u got beat and most likely the device is blacklisted, meaning someone reported it stolen, lost, etc. in which case u got beat for whatever u laid for the device. I've never heard of a network locked nexus, even the US carriers that had it on network u could plop any Sim in it and use it fine. I think u got played and it's a stilen/lost phone that has been blacklisted, hears what u can do, call your service provider and have them run the imei number and see if it's compatible, if it is blacklisted, they will tell you, but hurry up bcuz ebay only gives u a certain exchange/buyers insurance time, and after that 14 days or whatever ur hit

I've checked the IMEI and is not blacklisted.
If it's truly unlocked and it just gives me Emergency calls only maybe it's faulty then?
Do you think flashing a stick ROM solve the issue?

So many places, don't know where to answer. Try another sim card or it's hardware issue. In that case, return the phone while you can
Sent from my hammerhead using XDA Labs
Call your carrier and ask them if they need to validate the IMEI on their system? If there is no need for imei validation, I'd return it.
Try this: if it's a D821 dial 2945#*821# and go to "Network Lock"; if it's a D820 dial 2945#*820# and go to "Network Lock";
Now your phone should prompt for the unlock code. If it works, you cand get an unlock code for LG Nexus 5 from here: https://www.unlockradar.com/unlock-lg/nexus-5

You can't use Nexus 5s bought from T-Mobile on Sprint's network.
Sent from my Nexus 5 using Tapatalk
You should be able to use the T-Mobile nexus 5 if you call sprint and have them authorize the imei, no? Isn't sprint cdma? Doesn't sprint and Verizon use the sim slot for LTE only? Also, not being able to use a T-Mobile nexus 5 on sprint should not automatically mean the phone is locked to T-Mobile or any carrier.
