[CLOSED][Q] Unlocked Relay getting no signal on a non-TMo carrier

EDIT: No feasible solution found, so I had the device sold. Question closed.
UPDATE ON THE ISSUE: It seems that it would not recognize WCDMA networks (GSM works properly), hence no signal on my WCDMA-only SIM card. Any ideas?
Hello all, new joining the Relay 4G forums
Long story short, so I got my Relay 4G today, but it just wouldn't fully recognize my China Unicom SIM card. Symptoms and information:
1) No signal
2) Correctly displays my carrier's name, but says "emergency calls only"
3) Can search for available carrier networks, including China Unicom, but fails to register on the network - it says "unable to connect, try later"
4) The device has a correct IMEI instead of a generic one
5) Doesn't prompt me to enter SIM UNLOCK CODE when I first plugged in the SIM card
6) SIM unlocking procedures posted in the forum doesn't help - the phone should be unlocked when I bought it
7) It recognizes another SIM card from China Mobile (WTF!!) and works properly
8 ) China Unicom uses the 2100MHz band, which is supported by Relay 4G
So now I'm out of ideas... Any help would be appreciated. Thanks

...So this phenomenon means this really is SIM-locked? Good, I'll revert to ICS and try unlocking with that method...
One question: why doesn't it prompt me to enter unlock code when I inserted the SIM?

@croogrog It didn't turn out to be that simple... SIM unlock procedures didn't work at all even though I got all the timings right. I think the problem isn't caused by SIM lock... But what can it be?

More strange symptom: another SIM from China Unicom got recognized quickly after I inserted it. I don't understand this...

If other SIMs are working and you are able to call someone your phone was unlocked when you got it.
If your SIM isn't working it could be that you need a new one from your provider.
I had that problem years ago. My phone was too new ...or my card too old.

From a local importer at TaoBao (China's equivalent of eBay).
UPDATE ON THE ISSUE: I changed my SIM card for a new one at my carrier's but still won't recognize. Adding in the symptom that it can recognize another China Unicom SIM, I guess I can conclude that the problem lies within this particular SIM.

Best test would be to try another carrier sim all together. Not china unicom. See if the phone takes it. That way you will know for sure that it's unlocked and works. Unfortunately, there's no way to check if it's unlocked, other than to test sim cards
My next suggestion would be to consult samsung for a warranty repair, because your phone might be faulty. Or consider asking the seller that you got it from to send you another one. Let us know if you still need help

1. I checked with a China Mobile SIM and it works. Also, as said before, another China Unicom SIM also works. Only this specific SIM doesn't. It IS unlocked when I purchased it.
2. No way for a warranty - I'm in China and this is a T-Mobile USA device that many local "smartphone gurus" haven't even heard of, let alone "repairing" it.
3. The importer only has one such device in perfect condition (others have plenty of worn and torn), so exchanging is not possible...
I'm thinking of setting up an alternative solution for now...

More update on the issue: even on the China Unicom SIM that got recognized, it wouldn't connect to WCDMA/HSPA+ networks. Did an experiment: I used *#*#4636#*#* to adjust network modes, and when the device is on GSM only / GSM/WCDMA auto / WCDMA preferred, it would receive signal like normal; however, choosing WCDMA only, no signal is received. It seems like the real issue lies within the device after all...

...The Relay isn't a WCDMA device.

Even though the relay is a US tmobile device i would still try to contact samsung. They may be able to help you and it can't hurt. This is certainly not the first Relay to leave the US and incur problems...

If I understand correctly, the network mode menu option for WCDMA in the CM10 ROM is left over from the D2, which is a phone of similar spec which our developers based our ROM on. It doesn't do anything on the Relay.

But it DOES switch network modes... Or so I think, judging from the symptoms.
The first SIM only supports WCDMA(HSPA+), and when inserted, it can find my carrier's network but can't connect. On the second SIM which is compatible with both GSM/WCDMA, I lose signal only when "WCDMA only" is chosen, and under this situation the symptom is same as above. I assume that it can find my carrier's GSM network but not the WCDMA one.

Bump in vain. I guess I'll be selling this phone if the issue is really within the phone itself...

I don't think that it needs activation, since you are gonna use it for GSM. You will not be able to use it on CDMA though, needs to be programmed.

Please DO NOT buy unactivated phones... It will NOT have GSM part open yet... My DroidMINI is lying useless due to that and my DroidMAXX is working great (MAXX is like new used one)...

Droid Maxx in India
Here is another update.
Another XDA member got a new Droid Ultra last night. It did not work on GSM and it seems the activation on VZ got through (I don't know how). But when checked with VZ global support, they verified the phone and SIM are not associated with any account.
Anyway, GSM did not work. Then he tried Reliance GSM and it worked for a few minutes for calls and data.
Calls could be made and received. And then, suddenly there was an "invalid SIM" message.
So, who is blocking this? Verizon? or Reliance?
Another source tells me that the IMEI has to be cleared for international use. So VZ has to release this IMEI so that Indian companies can verify it to be genuine and not stolen, or invalid.
Now, the only way to get that done is with some insider contacts in Vodafone, Idea, Airtel or Reliance.

^^^^
I don't think it has anything to do with Indian operators... Everything has to be done from BigRed end, afaik... I don't think Indian telecos are following International database of BadEsn / IMEI...

This is all very strange... I THINK that the bad ESN is just relevant to verizon, and I also THINK that verizon is not involved in this. Or maybe they changed something. Also it is strange that for a while the phone worked and then not. I would call your provider and ask why.
It was clearly said that verizon is blocking only SIM for US carriers before. Also, HOW would they unblock it by registering in their network? If you connect to your local provier, verizon is completely out of the connection process. That would mean, that there is some software/firmware thing in our phones that is blocking it (read try unlock bootloader and flash another rom = last chance)

I traveled to India (Bangalore) a couple months ago. I used an Airtel SIM card while I was there, and it worked great. Of course, my phone had already been activated before I went.

XDA member Harsha has two Droid Ultras. One of them works and the other does not. So he took the IMEI's of both these phones to a local carrier Vodafone to check.
The working phone's IMEI was found in their database when they checked. The other one was not found - reported as invalid or not found.
I checked that one with Motorola after that. Motorola's database has Harsha's name against that IMEI. So, that database has got that entry.

Unlocking bootloader and then flashing which ROM? This will just complicate the matter further, with Moto and Verizon both saying we have no role to play in this. They might not even help in troubleshooting further.
What I understood is that local carrier puts you on the network and in a few minutes, it realizes that the IMEI is not found/ invalid. So you are kicked off. That is why two people were able to use it for some time and then they were out.
I am not sure why data works for some of the guys though. It should not.

Yeah. Activated phones work without problems.

No need for unnecessary speculations... If the phone is NOT activated in Verizon, then its GSM part can NEVER be used anywhere... PERIOD...
Further I checked (here) my working MAXX's IMEI and not working Mini's IMEI too. Both are saying valid...

Well, the IMEI on those overseas sites will show as valid since it is a valid device there.
But if you visit an Idea/ Airtel/ Vodafone store and ask them to check the two IMEI's you will find that the phone which does not work is reported as invalid IMEI.
Harsha has tried this with Vodafone, since he has two phones as well out of which one does not work.
Also, it is not true that if the phone is not activated, then it cannot be used on GSM anywhere. We have several reports on XDA where people have used brand new devices on GSM.

we Got gsm working if any one got gsm working let us updated

GSM now working for most phones
So, Motorola confirmed that an entire block of IMEI numbers was missing from the GSMA database.
While the cause for this is unknown, they were kind enough to escalate this to the GSMA authorities and get the IMEI numbers included.
Now, Indian carriers have synced their database and most carriers are working, but some are still not with some phones.
It is not clear what else is wrong with some of the combinations of phones, SIMs and carriers, but so far out of the five phones which were not working, four of them are working (out of those a couple are not working with one carrier).
Some phones are working with pre-paid carriers only and not post paid.
My phone is employee edition and still not working with Idea cellular.
In fact, after doing a factory reset yesterday, even Reliance CDMA is not working now. Strange.

My droid mini is now working fine with my regular Airtel postpaid nano sim.
Please share which operator Sims are not working.

Droid series - some more missing IMEI blocks I suppose
So, yesterday, another person contacted me stating that he just got two Droid Ultra's (new, never activated) and these are not working on GSM.
With CDMA, the data does not work, but the calls work fine.
Now, I have consolidated a list of phones and the carriers against which they have been tested along with the type of SIM and the type of connection (pre/ post paid) and send this to Motorola.
Perhaps the new range of IMEI's is also missing from the GSMA. But I will get confirmation in a day or two on that part.

Update:
Did a full FXZ install using House of Moto 2.0.
Then, did a four corner activation bypass as per the video here (which is for the older Razr Maxx.
https://www.youtube.com/watch?v=fYcZYZPGO2s
I don't know if that helped or the FXZ or both. After pressing corners first in landscape and in portrait mode, both, several times, I actually was able to skip the screen to some other screen.
After following the remaining prompts, it took around a minute to search for networks. I manually selected Vodafone IN and it took a few retries to register on that network (I have poor indoor coverage).
I tried with my regular service provider SIM and that one showed the network instantly.
No tried to update anything using WiFi so far.

I bought a droid ultra on eBay and took it to costa ricaand when I put a local Sim card the device gets signal and mobile data works but I can't make calls or send SMS because it says nno service even I has signal bars

Signal/Network problem

Hi guys,
I've been having this problem with my N5.
Its a d820 model, unlocked and rooted.
I have no signal, cant register to the network either.
I can use wifi with no problem too.
I changed the micro sim card with other carriers, same issue. I asked for a new micro sim to my carrier too (not cut), but still getting the same problem.
It's worth mentioning that the micro sim works flawlessly. Im using it everyday on an HTC One S and signal and data works perfectly.
When I first get the simcard on the N5, it asks for a reboot, after it comes back up, it shows strong signal, but I can't make any call or receive, no messages either.
After a few minutes, the signal goes down and it shows only emergency calls.
Going into mobile networks and searching for my carrier takes quite some time, but no matter how many times I try to select my carrier,it always comes back with not able to register in the network.
I did a factory reset, and went back to stock, and then performed the system updates to 4.4.4.
I flashed a couple of radios as well, but no luck.
The IMEI shows well, and its the same that shows on the box, so I guess no problems there with a corrupt IMEI.
Has anyone else had any problem like this? Any suggestions?
I've been reading some threads here, and I still have to try a different kernel/ROM, but if anyone else knows of a similar situation, I would appreciate any suggestions.

May be it has something to do wid preferred network...
If u use 3g go to dialpad
Type
*#*#4636#*#* phone info
Select modem as wcdma only...
If u use lte select lte only... See if this works

I think I already tried that, but cant remember for sure
Will give it a shot, thanks

Is the phone second hand?
Have you checked if the IMEI is blocked by the network?

sounds like you bought a used phone that has been blacklisted. if blacklisted, your phone wont work on any US carrier, and many Canadian carriers.

Yes its a second hand phone, and I don't know if it is blacklisted on USA, but Im in South America, so that shouldnt be a problem
And there are no carriers here working with N5 so they cant blacklist the IMEI either
(This doesnt mean that the phone doesnt work here, actually, my wife has another N5 that works like a charm here)

the carriers dont have to work with the n5 to blacklist it. in other words, they can blacklist any phone that connects to their network. as soon as you connect to the network, they know your imei and other info about your phone. anyways, they blacklist your imei, so when your phone tries to connect, it cant. the agreement that carriers have in the US and Canada, could possibly be for all of the americas, or, in south america, they could have their own blacklist.

googling, i found that carriers worldwide are sharing blacklists.
The GSMA, an international association of wireless carriers, also keeps a database that wireless carriers worldwide could check to prevent stolen phones from being reactivated on their networks.

yup, thats the best thing to do. the people that first answer the phone, customer service, probably wont be able to help, maybe someone in tech. or, use this website to check(there art other sites as well).. http://swappa.com/esn

Well I just checked. IMEI not blacklisted on my carrier, also checked with swappa, not blacklisted either.
I used the *#*#4636#*#* to select wcdma as well as other options there, but still no go.
Also, under Mobile network settings, changed the preferred network type to LTE, 3G and 2G, but no luck
Tried Choose automatically the network, but still getting the message that its unable to register to the network right now and that I should try again later
I guess Im left with flashing some other ROM/kernel to see if it helps, unless someone has any other suggestions

The phone is d820, but I know it works here (my wife has the same one), network 2g and 3g work well here, LTE is the only thing that won't work here with this phone but I don't care about that

If the problem is wid radio flashing a different rom won't matter ..
Have u tried flashing a factory image ?

I know flashing a new ROM wont help with radio, but I've seen that using *#*#4636#*#*, going into phone information and then Select Radio Band, gives me an error and force closes.
I've seen some threads about that, and someone saying that it was working on a CM ROM, so I was thinking of trying that in order to be able to select the radio band and see if that helps.
About the factory image, yes, I used the google images to go back to stock, and then performed the system updates.

Well I flashed Slim Rom, and was able to get into *#*#4636#*#* to change radio band. Tried them all, no change.
Played around with the preferred networks and no luck either.
I'm officially out of ideas, but I'll keep digging around to see what I can find.
Any suggestions welcome.
Also, I know that there is a known issue with the GPS signal on some Nexus 5, and there are a few videos on Youtube showing how to fix it (basically opening the back of the phone, and sticking a piece of paper under the connector).
Does anyone know if there is something similar happening with the radio? Does anyone have a photo of the phone showing which part would be the antenna?
One additional thing I noticed.
If I switch, or just take out and reinsert the micro sim, the phone asks for a reboot. After doing that, when the phone boots up, I see I have network (full bars), going into mobile operators, I can see my carrier, and I can register too. But I cant make or receive any calls or messages.
During this 10 minutes that I have this sort of fake signal, if I go into *#*#4636#*#* and phone info, I can see my carrier, but it doesn't show my phone number. Weird.

[Q] 3G not working

My new Honor 6 H60-L02 doesn't seem to have a data connection. The telephoning/messaging works well, but when I am out of wifi range, and want to use the internet, the message I get is 'no network connection'.
Any help appreciated.

Sorted!!
It was my sim card settings, OK now.

Which settings you mean? I've got the same problem on h06-l04 and did everything like deleting the APN, tested APNs from other providers etc. - nothing helped. The SIM shows h+ and h all the time, but when I try to open a site or try to update my apps over google play the connection works a few seconds up to a minute and then the connection got lost again. It never happened on my galaxy s2.

I used the APN settings on my sim card providers web site and they worked perfectly. If I am not in a wifi zone the phone switches to h+ and performs very well.

So my new huawei honor 6 is not supporting 3g. It only shows edge connection. How to sort this out? Please help.

What model do u have? H01, H11 - won't support Euro 3G, thay are only for China. H02 and H12 - should work fine with 3g. H04 - Should work fine with 3g and 4g in your country.
Also please check if your carier provides 3g service.

I received huawei from Uk. Honor 7, Network unlocked but i cant access 3g to 4g service data. It only works when i turn to 2g, edge and very slow. Any help?

3G/4G issue
I'm also having the same issue with my Honor 6+ which i bought last month from dubai. I'm trying to use data connection using 3G/4G in india as i'm residing in India, but even after following all the required settings that are provided by my service provider and the other trouble shooting steps i'm still no where. It always displays the 3G/4G icon at the top but never works. I doubt if it is something to do with the software/firmware version. Please suggest.

I'm also having the same issue with my Honor 6+ which i bought last month from Malaysia and using in Bangladesh. I tried airplane mode on and off, it shows 3G for few moment or minutes but then again it becomes edge mode. Please help me out from this problem.. thanks in advance..

I live in India and I bought my Honor six plus online from a local retailer, and my phone can only access 2G data (or EDGE, apparently ) which is too slow to support anything. At first, I thought it was a sim card issue but I tried using the same sim in someone else's phone and that person's phone had no such problem. Even my brother's Iphone faced nothing of the sort. Any one know how to fix this?

Check on the back of the phone for phone number. On my honor 6, on the back on the lower part are 2 lines with text. on the second line I have found my phone model: H60-L2, in my case. Then you can check with, for example, http://willmyphonework.net/ if your phone model will work in your country. I know for example that my phone model will not allow 4G in all European countries.
If you prove that your phone is working in your country than its a matter of settings. You can try:
- Place the sim card with a data plan on the main sim tray. Honor 6 not rooted and running stable ROM will allow data only on the first tray. In Settings -> Dual Card Sim Management you can see which card is in which tray. If necessary switch the sim cards into the other tray.
- Check your settings and here the most important one is the APN. Make sure that the settings of your operator are correctly set in order to have mobile connection.
Generally the 3G network should at least be recognized, so if your phone is not registering with a 3G network then either it is not hardware compatible or you have placed your SIM in the wrong tray. Most probably is the first option and what you can do is to change the phone...

Man...i was having the same problem...well just 2 mins back!??
I have marshmallow update...and wat my problem was that the apn was set, though correctly, but in upper amd lower case....
And it seems apns are case sensitive...so check it!

Honor 6x is my latest mobile, which i bought a week before, it's seems like the mobile having data connection problems. till i'm using 4G sims but i'm not getting at least 2g speed, most of the time i'm not getting internet connections. at the same time it's showing H and H+ symbols ...
if possible, someone pls help me here.

4G LTE on Sony Xperia XZ from the UK in US?

I'm not getting LTE on my Sony Xperia XZ with AT&T. I'm in the U.S but got the UK version from Clove UK because of the lower price and freebies with the preorder. The US and UK Sony Xperia XZ are the same model number and the whitepaper has all of AT&T bands. Both are F8331 meaning there is only one Single SIM version. However the most I get is HPSA (3G?). Calls work fine and voice is very clear and I get full bars, however I can't get LTE anywhere. My friend that is on AT&T and has an iPhone 6S gets LTE with no problem.
I'm thinking that it has to do with the LTE bands being disabled or because it is a UK phone. I understand not getting Wifi-Calling or VoLTE because I didnt get the phone from AT&T but rather unlocked. But I should be able to get LTE, I might be wrong though. Could I possibly get the problem fixed by flashing the phone to a U.S firmware maybe? If anyone could help I would appreciate it.

Got the same phone from Clove on AT&T and LTE is no problem. The issue is most likely IMEI related. I have been using Xperia devices on AT&T for years and this has given me issues in the past. IMEI numbers are recycled and since Sony phones are not carrier issued their IMEI numbers are not loaded in AT&T's database. It most likely is linked to a 2G or 3G device from years past. Give AT&T an IMEI number from an AT&T LTE phone and you will access LTE. Also check APN to see if it's correct.

Yes don't flash the US Firmware, you won't get the fingerprint scanner, I bought the US version of the phone and Flashed the UK version, instead of LTE now shows 4G but is the same just different nomenclature

I can't speak for other countries, but the Singapore firmware reports as LTE on AT&T. But, it doesn't work until you go to Settings -> More -> Internet Settings and let it download.
Then, if you go to Settings -> More -> Mobile Networks, you should see the different AT&T APN's.

A million thanks. Everything you said was spot on. The IMEI as you said was not loaded into the AT&T database since the IMEI for my Xperia XZ is 14 digits vs 15 for an AT&T phone. I asked a friend for his IMEI and went to an AT&T store and did what you told and now I have LTE! Of course it appears as 4G on my Xperia but it's still LTE. Again thanks for your help.

Thanks for your help also. I figured that flashing the US firmware would disable the fingerprint scanner. My phone now shows 4G after I tried the solution to the first reply. Good to know it's the same as LTE. I don't regret buying the phone from the UK bc everything is working out fine.

I tried what you suggested but it still shows 4G. The options are still the same. Apparently it is the same as LTE just shows up as 4G. Thanks though for the idea. It was worth a try.

In the UK LTE bandwidth is marketed as 4g.
You've purchased a UK Sony with UK firmware hence you will see a 4g symbol rather then LTE.

Not sure what you are asking for, but I just followed the instructions from other post don't have the link at the moment, install xperifirm select the uk rom and it creates the ftf file for you, no need to worry about removing the xml file, I even forgot to put the phone on debugging mode it failed at first then I retried and it worked

Thanks, I figured it out. Appreciate the response. :good:

Thanks! That makes sense. Is there a way to test the speed? And so you are saying 4G is LTE, is that right? My XZ Premium, also from Clove, now says 4G so I should be good to go, right?
