I was abroad for some days, and I was able to use the sim card, when I came back to the origin, the local sim cards aren't able to connect to it's tower, I've tried different sims and even those sims aren't able to connect. But if I use those sims in other phone they are working.
I have tried formatting my phone but even that didn't help.
I use a HTC Desire Eye, Custom rom (S-ROM).
Please help.

did you contact the local carrier company?, maybe it has something to do with global roaming..

Finally got the password for this account, and yes i contacted the carrier, they told it's fine on their end.
One thing I noticed is that, I just tried something today. When the range was full (5 bars) my net was working. When it went to 4 bars (it was still working) and on 3 bars (there were some problems like the net became slow) and then on 2 bars the net was slow as hell. And I won't get one bar, directly it'll show as no service.
Aaand When I manually search for towers, I can't find any 2G/3G towers. I can see only 4G towers.
Do you think it's a problem of antenna? Or the radio.img got corrupted?

it could be a hardware issue, you appearently did nothing that could cause the modem to corrupt.

Just thought I'd comment, I bought a WiFi dongle and apparently even my carrier problem has been fixed, don't know how, or is it just temporarily, but it seems fixed.
I even get 1 bar now. Just need to try to see whether my net works or not with 1 bar.

I bought an infuse 4G in 2011 in USA then, the same year, I brought it with me in Italy, I unlocked it and it worked since then both in USA and in Europe. I deeply love this phone.
A month ago I accidentally broke some pins of the SIMM socket and then I thought to start using the infuse as a guinea pig to play with android and customized roms.
After many issues and trials and many "return to stock processes", I finally managed to have a working CM9 installed on it. It worked so well that I decided to repair the SIMM socket to use it again. I brought it to the repairing shop and I've got it back a few days ago.
Unfortunately, both with the american and italian SIMM cards I can only call the emergency number (911). Basically it can not register to any network. (btw I'm currently in Italy)
To my understanding if I can call and talk to 911 it should mean that the repairing was good.
I also called my provider to see if my IMEI number is blocked for some reasons but they have confirmed no bad records.
I tried returning to fix things following several guides like:
UCLB3_Unbrick_1.1
Odin_UCKE3_v2
No Voice or Data service after install of CM9 - ##72786#
Recover EFS
but I don't see any way out. The problem is still there and it doesn't change, doesn't matter what I do or what ROM is installed.
Unfortunately, I'm kind of lost here because, apparently, everything works and I don't have any error notification (or simply I don't know where to look at to make some debugging)
Do you have any idea, suggestion?
Thank you!

My only thought would be did they really fix the pins? Seems one of them still isn't making contact. Return it to stock then return it to the shop where you got it fixed and say you are still having problems.

i second this but if the shop that you send it to was in the US then its gonna be a while till you get it back but if they end up not being able too then i would suggest buying a new infuse since its about $80-100 on amazon which you would be able to unlock yourself then start from there but yea go to that shop and if they say its fixed try the sim in front of them to make sure it is fixed because returning to stock fixes most if not all issues

I should add that 911 will work whether a SIM card is in or not, valid or not, working or not. Emergency Call is a safety feature that doesn't discriminate (will connect to any network available). This is why telco's ding you with a 911 fee every month rather than charging you for using it when you really need to.
Thank you all for the suggestions

ha! that I didn't know and it changes EVERYTHING!! I thought that being able to call 911 mean I had no problem with the SIMM socket. After whatever you've told me I do believe that most likely the problem sits in the SIMM socket.
One question though: let's say that it wasn't welded well, is it then possible that I can see the SIMM number in the settings panel but it's still not working?

Forgot about that listing. Think I know why. Just went to that page, and I get an "Unknown" for that value (and my phone portion is working fine).
So that's mixed information, but a pin not making contact still covers that issue. But what it could be is that Access Point Names or Network Operators is out of whack (these things can apparently stay the same between flashes - or at least restored backups - for some reason).
To get to these two options, go to settings, the equivalent of More... under Wireless & Networks (sorry, I'm not on stock at the moment), and select Mobile Networks.

So I just have got back my phone from the repairing shop and ... it works!!
So I confirm that there was an issue in the welding of the SIMM socket. So this means that it's possible to see / access SIMM information if one of the pins is not connected.
Unfortunately the guy wasn't capable to tell me much about what they did exactly (don't ask, too long to explain ) so I don't know exactly what was causing the issue but I'm pretty sure it was one unwelded PIN.
It's also definitely true that you can call 911 even if the SIMM is not working properly or is not well connected to the device.

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.

I will check on that, I think I can just call my carrier and ask if that IMEI is blacklisted or not

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

also, what kind of nexus 5 is it, a d820 or d821? it would make a difference signal-wise. ones for north america, ones for europe. honestly, i have no idea which you would need http://www.phonearena.com/news/Differences-between-the-two-Nexus-5-models-D820-and-D821_id48985
I don't know if the problem is with the carrier, since I'm using the very same simcard with another phone and I have data and network with no problem.
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
I'll keep looking just in case, and I guess tomorrow I'll flash different ROM

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.

Has anyone got any solution of this? It's been quite a long with this issue, I've searched a lot of topics but no solution.
I have the same problem. Phone don't see simcard somehow. Flashed latest original firmware works for 1 min. Pull out trace with sim insert it again works for 2 min and stops working. When it works for small amount of time i think IMEI its not blocked and almost sure its software issue. Yesterday flashed different roms and CSC and modems no luck. SimCard changed for new one. Have someone some clue what to do ? I can provide logs if needed.
After instaling Samsung Phone Info app from market gsm wen't back online. Probably a coincident but when I go to Hardware screen ther was no modem model. I tap it few times. Close apk run it again modem went show itself after a while GSM signal is back.
After reboot no signal again. Then i make magic with phone info apk again and signal want back.
This apo make some sort of device discovery and reset modem device / driver or this is pure luck.
So me and my friend swapped our Ones because mine had a broken aux port and his was fine, but his casing is pretty battered. So my phone which is now his, its been fine for a few weeks but a few days ago, the network has been playing up. He cannot make calls, but can send texts. But, in network settings, no networks appear when you go to select one. The APN settings are correct, signal is a bit hit and miss, sometimes its there, and sometimes its there but cannot connect to the internet. WiFi works fine. I also tried swapping SIM cards and the same issues were happening with my SIM or his SIM.
It was running Sultan's CM13 ROM with the "firmware_fixed" firmware/radio. I thought maybe something had gone wrong so I then flashed Sultan's Lineage OS and it is still having the same problems. I've tried a full wipe and factory reset, no luck.
Does anyone have any suggestions on how to fix it? or could it be a hardware issue?
Thanks,

My friend is on EE and I am on Three. Both are different networks, and with both sims, it does the same thing, It cannot find the network. I have tried both sims in the other OnePlus One and it detects the networks with no problem.
I guess the next step would be going back to full stock and see if that works. If that is a no go, I can only assume its a hardware issue
Hi again,
I have tried again to fix this phone but I think I have exhausted all software options. I fastboot flashed all the original stock files, completely went back to stock ROM and the same issues are there. It gets signal, and it says that mobile data is working, but doesn't actually connect if i open the play store etc. I managed to get a call to work for about 5 minutes before the call ended on this phone, but was still going on the other phone which called it. It does allow calls sometimes but they drop out, other times it wont dial at all.
At this point, I can only assume there is some antenna damage or something similar? I did a quick google and worked out that the antenna is on the daughter board on the bottom of the phone, and there is also an antenna wire also. Would it be worth it to buy these replacement parts and see if this would fix the issue?
Thanks

Its my friends phone now, we traded. And he said he hasn't dropped it or anything like that. But judging how battered the phone is that he traded me, he might have damaged it and not realized. It had been working fine for me in the 2+ years I had the phone. And after the trade, the phone worked fine for him for a few weeks. Its very weird. I've tried my SIM and his SIM in the phone, both sims work fine in my phone but not his.

It had been working fine for me in the 2+ years I had the phone. And after the trade, the phone worked fine for him for a few weeks. Its very weird. I've tried my SIM and his SIM in the phone, both sims work fine in my phone but not his.

I see,so if you believe that there could be a hardware damage,you can go with the network antenna and see if it fares.
Hi everyone,
has any of you ever had network problems, as can be seen in the video?
For a few days now both network connections have been breaking down when I try to make a call. But that doesn't always happen. Sometimes I can make 10 calls in a row and everything is fine, and sometimes nothing works. It doesn't matter which SIM I use to make the call. The problem occurs with both cards. If that happens, then either directly when dialing a number, or immediately after hanging up.
I've never seen anything like this. And I wonder if it's the software, the SIM tray, one of the cards or the network operator itself.
Can anybody please help me? This is quite annoying.
PS: Sorry for the German settings. „Keine SIM-Karte“ = No SIM card // „Dienst nicht verfügbar“ = no service
Clear sim tool kit data
Network reset
Clear system cache
Make sure the access point names are correct

Thanks for the advice, but this didn't help.
I did these 4 steps, but the first time I tried to call, both connections dropped again. Can there be a hardware problem at all? Looks more like a software issue, doesn't it?

The sim card, the usual hardware suspect...
They can be damaged by ESD; handled like a stick of ram.
ESD may not manifest itself for weeks, months even years. Insults are cumulative.
It's not expensive but it is a pain, try to not damage it as it left the plant A-OK.
Just like ram sticks poor handling is the cause of almost all sim card failures.

So, am I getting you right? I just go to the store and have the SIM card replaced and everything should work again?
I've tried a few things now. If I set SIM 2 to GSM, everything is fine. The connection doesn't break. I believe it is the 3G connection. And that's why these crashes could occur when I make calls. SIM 2 doesn't support VoLTE, so it switches to 3G.
EDIT: I've tried different things now. I swapped SIM 1 and 2 back and forth. I also used my two SIM cards alternately with a third SIM card. The problem persists. Could a hard reset help or should I send the device for repairs straight away?
Same problem here. Setting sim 1 to GSM only, and sim2 to LTE fixed my problem for a while. This has something to do with dual sim handling.

This is soooo anoying. Have you had this problem for a long time or did it only come recently? Could this have something to do with a recent update?
I bought the phone a month ago, and while I was setting it up it received 5 updates including android 11. So I have no experience prior to Android 11.

Damn, same here.
Have you tried cleaning the sim cards with rubbing alcohol?
Then put them back without touching the metal contacts.

No, I don't see any point in doing that. I swapped the SIM cards and even tried other cards and the problem was still there. If something had to be cleaned, it would be the SIM tray. But as already written, there are no disconnections when a SIM is operated in 2G. I think that rather means that it is a software problem.

I have this same problem with phone dropping off the network. For me it started after the first Android 11 update. I have full signal levels at home but if I try to make a call signal level for both sim cards drops and I get a message that mobile network is not available. Doesn't happen always but pretty often.
I'm pretty sure it has something to do with how the phone handles dual-sim operations...

I am glad, I am not the only one, who is facing this problem. I already thought, I have to send my phone back. So, we have to wait for a fix.
Must be patient. There is also bluetooth problem(disconnecting from devices). It looks like they were too fast with android 11.
Since the last update(.159), i also have the drop out problem. Starting to feel sorry for buying it...
So, let's hope the new .222 update, which has just arrived, will fix this.
EDIT: no, it doesn't.

Yeah, I even had to restart after the update, in order for the second SIM to become active...
Edit - and the problem is even worse. Almost after every incoming call I lose signal to both sims...
Edit II - I wanted to try to switch sim 2 to gsm only network, and noticed that there's 5G available for it too, after the update. Before that there wasn't such an option....

Since I use the second SIM only for business calls, I have already set it to GSM only. Today I noticed that I still have outages. So apparently to force 2G is no longer of any use. :/
About 5G: It has been active on my device since I got it. Perhaps there was an update on this from your carrier.

same here and the problem is very annoying cause my everyday job is in a car. is 100% software problem. 650€ for a phone you can't use it as a phone.
Hi, I don't have signal drop but yes the WiFi drip in my room, I had a xz premium and never happened on it
