"NO SERVICE" Can't get signal anywhere, anyhow. - General Topics

My XDA II is not getting any signal from anywhere.. Flight mode is off, wireless is on.. Beside the signal icon is an exclamation mark that just stays there. It just says "No service" when tapped on.. I've tried other sims but nothing worked. The sim cards work fine with other phones.
The Xda II detects the sim card because it can read it's phonebook thru "sim manager". I've tried searching network and stuffs but still nothing. I did the soft and hard reset but to no avail.
Can anyone please help me???? Is this a usual problem??

Is it a new XDA II ? or second hand bought ?
Did it ever work ? When did it stop working?
Did you do an upgrade ?
What radio version ?
What model ?
It could be you have a stolen XDA II and that it is blacklisted.
It could be that the upgrade went wrong and you have no radio.
It could be that it is set to the wrong band. 850/1900 900/1800

SEcond Hand. Haven't done an upgrade.
I just tried using other network's sim and it worked.. only sims from the network it was bought from don't seem to work..
How do you change the bands?

About those bands I don't know much. I just read that it is a problem, but mostly in the US.
It could be that it is blaklisted at one operator, and that it works with other operators. But I was under the impression that all operators should use the blacklists.
You could call helpdesk/go to shop of your operator and ask why it doesn't work and if it is blacklisted.

Would they confiscate the unit if it is blacklisted?
Thanks for the replies M4IO..

I don't know, I've never had one.
you could just phone them from an anonymous phone, tell them that you want to buy a second hand phone, but first want to check.

If you know anybody who travels abroad, ask them to take it to another country, if it works there then you know it is blacklisted in your country.

No network in US but works fine in Canada

Hi guys,
I'm new to the forum. I've tried searching for some answers but can't seem to find how to resolve the problem. I'm quite new to using PPCs so let me know if there's any information that you guys need.
So my phone works fine in Canada using Rogers... but everytime I go to US, I cannot detect a network for my phone and there's a "!" at the top. I tried searching for a network and it says "no network found" or sometimes it tries to register and then it fails in the end. In US, my phone automatically shuts off... I have no idea how this happens but everytime I go to look at my phone after leaving Canada, it's off. So when I go to turn it back on, there's no phone signal. I have no idea what to do as I'm not very familiar with PPCs.
Thanks for the help!
Which phone are you trying to use? Guessing Touch Pro?
Is international roaming or data roaming added to your account with Rogers?
Hey I have the HTC Touch Pro... yeah I've used this sim with my eten m700 before and it works fine. It just always seem to be searching for a network then it can't find any.
Thanks!!!
are you a prepaid customer? if so, Rogers doesnt allow roaming outside of canada.
Hey there... Just figured I'd pipe in here...
I am still using a TyTN (shopping for a Touch Pro today), and although I was able to always use my phone in the states, since my last firmware upgrade (WM6.1, new radio stack)....
....I can't get any service when I cross the border.
SOMETIMES I'll get 10 minutes of service over the course of an entire day. Very strange.
It is obviously firmware-related... Good luck with your phone...!
Thanks for all the help guys...
Nope I'm not a prepaid customer... should I be upgrading something on my phone to see if it works? Sorry... really don't know much about PPCs here!
just out of curiousty, have you called Rogers to ask for an updated OTA to be pushed to your SIM?
I've contacted Rogers and they said it has nothing to do with them... it's my phone! Should I contact them for the OTA? I'm sorry to be so noobie but... what does OTA do?
Thanks again!
Anyone help please!!!

[HELP] Can't connect to any network in UK

Hello
I have problem with my Sensation.
I bought phone year ago (on polish equivalent of ebay), from someone who lives in UK and he send me it to Poland. It worked perfectly there, till now.
Two days ago I came to UK, and since I switched phone ON after getting off the plane, I can't connect to any of the cellular network.
I am sure that SIM slot is OK because phone asks me to enter SIM pin code.
When I am trying to manually select network I got 'Your SIM card does not allow a connection to this network', and when automatically 'Unable to connect to this network at this time. Please try again later.'
Wifi and GPS working fine.
I dont have a clue whats the reason of that, where the problem lies.
Phone has ARHD 6.7.2 ROM, firmware 3.33.401.106.
Any help is appreciated as I need phone badly, to have mail and internet access throught the day :crying:
PS. I am starting to think that UK seller could scam me, and sold me phone with blocked IMEI or something like this? :/
Hi have you tried to change your radio And ril? This could help you regain signal. I can't recommend a particular radio and ril because we live in different areas and it will be different. However you can start by experimenting with the generic ICS radios and rils and see of one of those will reconnect your signal.best wishes.Hope this helps solve your issue!
sent from HTC sensation, soff, 3.33 firmware, viper Rom, sense 4.1, kernel version PYD-X stable 3.1, mugen battery 3800mah. Please press thanks if I helped in anyway.

Sounds like your Polish carrier/SIM might not be allowing international roaming. Get a PAYG SIM for a couple of quid and try that. That'd prove the phone side of things.
Try
Try putting in a diffrent Sim card to see if it's that.

If your home network doesn't have an agreement with UK networks then your SIM won't work, not sure if this is realistic as I thought they were all only to happy to help others take money from us. Try a UK SIM, if that doesn't work then your IMEI is probably blocked in the UK, but not in Poland.
It's a simple answer Your phone has been reported as lost/stolen in UK and IMEI has been black listed. It's now paper weight in UK.
Pogon telefon w PL i kup sobie inny w UK.
Sorry for not mentioning - ofcourse I tried other sim cards, like o2 and vodafone - neither of it worked. My PL carrier sim worked in roaming in different phone.
So it looks like IMEI is blocked, I just wonder if I should go to the Police to check this out but I dont want to have it confiscated :/
Butif its true, Im not going to leave this scammer unpunished - I'll try legal action :/

Instead of legal action why not just find him and remove a thumd. maybe both thumbs to be sure.
The sad thing about having an IMEI number on the black list is that it can't come off that list. At least from my experiences.

Apart from it not being a paperweight. Revival is possible but ILLEGAL.

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.

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.
Lg nexus 5 network issue
i am facing the same issue with exus 5 .In my hometown in India,the phone simply shows "Emergency calls only" and shifts to normal working mode with full network coverage once i travel to other parts of my state (parts which probably has a better signal strength ,i dont know ).i have tried out changing the sim card and a factory data reset ..Both didnt help ..

[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.

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.

Mine just had 2g network on TMobile network USA
hi guys if want to solve this problem i know this is very late replay like a year xD but this can be fixed by turning airplane mode on then off
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.

5G Phone Stuck on 2G

Hello!! I'm new here! I hope I'm posting this in the right place. I have a TCL 30 XE 5G (T767W) from Metro by T-Mobile and I had it sim unlocked by an eBay seller who had me hook it up to my PC via USB. The settings menu says it's still locked but it does accept sims from other carriers so I think it's unlocked. The problem is that it won't find any service at all with any sim other than the original Metro sim unless I set it to 2G only mode. Even selecting my service provider from the available network list doesn't work. The only way I can get the phone to find service is to force it to connect to 2G then change the network mode to LTE and then finally set it to 5G and that doesn't always work either and even when it does it's only a matter of time before it randomly disconnects and is left forever searching for service but never reconnecting until I set it back to 2G only mode again. All this is happening in a city with great T-Mobile coverage and all of the sims I've tried run on the T-Mobile network. The only sim that works without any fuss is the Metro sim even after the phone was unlocked. I'm using the phone on a T-Mobile MVNO now but it always disconnects sooner or later. I don't understand how a new phone can't automatically find an LTE or 5G network without first connecting to 2G and it doesn't find that either unless it's set to 2G only mode. Aside from the obvious inconvenience this causes, T-Mobile plans to shut down their 2G network soon at which point this phone won't be able to find service. Has anyone else run into this problem? I have two of these phones both are doing the same thing. Did something go wrong with the unlock? Is it a software issue? I tried asking my carrier for help but they can't figure it out either. I appreciate any help or info anyone here can offer. Sorry for the long post.
i suggest taking into a service and getting it there unlocked. perhaps your method prove faulty.
