Installed my first rom a few days ago, leedroid 2.2.2. Also installed the recommended radio for it. My phone was perfect on a T-Mobile Uk signal.
Today i had my number ported over to giffgaff which uses O2 network. But my signal has been up and down all day and disappeared at times. Other O2 users around me, including one with a Desire HD, had no signal problems at all.
So my question is, are different radios better for different networks, or just different radios work better with different roms?
As far as I have read and heard, different people will profit from different radios. you just need to try out some other radios and see which one goes well with your new provider and the places you go. location can also affect which radio is better for you too. just try it out

Yeah it's just a matter of trial and error, diffrent users get diffrent results from diffrent radio's. your best bet is to try a few, see which ones work best for you
Thanks for the replies. Going to try a few different radios now.
What's giffgaff?
If it's a carrier, sometimes even though they may use signal of major networks they might not necessarily be the same signal.
For example in UK, Virgin uses the T-Mobile signal but the signal strength is often different.

According to their site the signal is the same. The users say it is the same too. I think O2 actually own giffgaff, but just have this separate company for whatever reason.

Its easy and true, virgin dont own there own antennas, so they buy air time of other networks, these networks obviously value there own customers more, so when antennas become full, they will drop the signal partially or totally for the other company. The same happend with 3 when they first started. They were using o2's network. But eventually had to develop there own because of all the dropped calls, there customers were having

Who do you work for? I used to work in the online returns department for o2 and i can assure you thats exactly how it works. Each "cell tower" as you put it, can only carry a certain anount of calls, once this limit is reached, calls are deferred to another "cell site" or in the case as i explaned dropped completely, a simple google search will show you the same information, so please educate yourself in future before calling me a liar!

so you work in customer care and think you know how the network works? interesting.
i operate an HLR/CNTDB (google HLR, you won't find infos about the CNTDB) for t-mobile germany (now deutsche telekom). i get payed for manipulating subscribers in this central database of every GSM, UMTS and LTE network. but i am sure your experience in customer service has tought you the details of subscriber administration and radio network operation better than the trainings i got...
btw, i never doubted that cells can resize themselfes (called "breathing cell" btw), it happens all the time, everywhere, every day. but the algorithms involved do not care which reseller sold the simcard to the customer. there are mechanisms that can kick out certain cards, but network operators will use these only if forced by higher powers, like catastrophic events. and even then it doesn't work as you described. network access is shut down, then reopened in this order:
1. network technicians (me for example)
2. EMT (police, medics)
3. politicians, secret services, other officials
(4. maybe other high prio subscribers)
5. everybody else, gradually and with a random distribution.
the mechanism that is used here is called the ACCESS CLASS of the simcard.

I've tried unlocking the phone again and nothing changes, I need help pleaseeeee! Idk what to do and I can't afford to buy a new phone right now.:crying:

Are you sure its a GSM network? As far as I know, the galaxy s is incompatible with cdma networks. I could be wrong tho.
Sent from my LG-P930
Movistar in Spain uses GSM, not CDMA, but the bands are not the same for 3G, that'e your problem. You won't get 3G on Europe, only in the US with AT&T, Canada with almost any carrier, and any country from Mexico to Argentina.
Maybe in Australia/India you can have 3G, I don't know, but there are some members with a Glide from India, they can answer this better than me.
Thank you, I'm stupid, I should havechecked that before buying the phone

On the samsung galaxy s captivate it says:

I think I may have good news for you, check this:
http://www.unlockit.co.nz/mobilesettings/settings.php?id=27
There's a good chance you have to set the APN settings manually, the above link shows you how to do this. These are the settings that tell your phone how to get onto the data network, if those are not already in the phone or set automatically. Give it a try, your problem has occurred more often and this was the solution!
Setting the APN manually should get internet working, but since the phone doesn't support the bands needed for 3G in Spain, that won't solve the 2G only problem. Still, working 2G data should make it at least fairly usable until you acquire a phone that supports your local bands.
Perhaps not in Spain then, but it works elsewhere in Europe. I live in The Netherlands and I get 3G. Haven't looked into the frequency bands, but it all works perfectly here. There are several other European users here, and I've never read anything about not having 3G because of frequency band issues.

Hello,
I appeal to all the users that have samsung galaxy s4 mini duos (i9192) to give me a honest opinion on their experience usage about this issue
I want to buy the phone because i have 2 sims, work and home and need both always on but i've been read that this phone has major problems with network signal such as:
"Poor network performance. I'm forced to restart 4 to 5 times per day to regain the network access. I checked from my service providers, no issues on their part. Dual Sim a failure. Apart from network issues, the design, ram performance are average. I'll recommend not to buy this instrument unless the dual-sim network problem is rectified."
Like this, there are many more in samsung phone forum.
Anyone can give me their opinion?
False. I'm using it without problems with two sims work/private. Signal strength may be lower, but it's not so bad. Device is very fast, in antutu it has more points than 4 core htc one x+ or galaxy s3.
Software is bit buggy, but nothing serious.

Thanks for the quick answer.
Yes, i have read many reviews and all shows very good results. But if you go to http://reviews.in.samsung.com/7463-en_in/GT-I9192ZWAINU/samsung-galaxy-s4-mini-reviews/reviews.htm you will see the very bad opinions.
Seems that the phone in bad coverage areas lost signal and don't regain signal unless you restart the phone or the network. Have you already been in bad coverage areas?
It will regain signal. For example yesterday - I was in underground parking lot and signal was very poor to none, but somehow I've got the incoming call when moving to other spot.
Maybe it's firmware related. I've updated manually to amh2 version through odin. Mine new csc is ser - Russia
Wysłane z mojego GT-I9192
Anyone else that has not experienced this problems?
I would like to know this also, I'm considering buying it solely because of the "Dual Sim" but I keep reading lots of people complaining about the signal issues.
I dont have any problems with my I9192 been in my hands for 2 months by now the network problem you describe it's very rare just couple of times since I've been using it but I've turn on and off airplane mode
for me it's a really good phone

Same problem
I also have the duos version. Once the signal is lost/falls in the dead spot region, it doesn't come back a automatically. Fed up with this.. after buying such a high end phone, restarting all the time to get network! What is the use of fast processor and all stuff if we can't make a phone call with it? And after reading the comments on the below page, it is clear that this is a known issue of the model:
gsmarena.com/samsung_i9190_galaxy_s4_mini-reviews-5375.php
Any solution for this? The handset has turned out to be useless.
I have not had a problem like this with mine, it works perfect. I live in a bad signal area and if I go down stairs in my house the phone will lose the signal , when I go back up stairs the phone always regains the signal with no problems.
I can't fault this phone, it's ten times better than my last one, HTC Desire V

Thanks,
Only the fact that you mentioned you have to do airplane mode 2 times is just severe enough, because in a phone with this price range that's a problem that should NEVER occur, and you can be the lucky guy that just has good coverage signal all of the time.
I came to the conclusion that it happens with much moore models than the ones that not happen.
I'm going to order the phone even with this feedback hoping that i have a flash of luck and my phone doesn't have the problems, because i've been waiting months for a dual sim phone with top performance and this seems to be the ideal phone to me.
I will post my experience here, if anything goes wrong i will try to sell it.

Same Issue with Samsung GT-I9192
Hi All,
I am facing the same issue with my Samsung GT-I9192, which I purchased on 1st Sep.
I am using 2 simcards, one being Vodafone and the other Idea, India region.
Surprisingly the issue is only with Vodafone, where the signal after dropping (very frequently) does not refresh.
In case of Idea simcard, the signal refresh is working fine.
I am not able to understand if the problem is with the service provider, sim card, hardware or the software.
I used my vodafone simcard with Galaxy Core (another dual sim phones), and they seem to work fine,
which gets me all the more confused.
The only difference that I notice is in the Mobile Network Type.
Its EDGE:2 for Vodafone and UMTS:3 for Idea, wonder if this has got anything to do with the network issues.
I did the default available 2 firmware upgrades since purchase, they seem to have worsened the problems.
Let me know if you are facing the same issue, with the same service provider.
Need to keep a close watch on the solution, as it seems to be affecting more people than expected, surprisingly couldn't find any issues a month back during the time of purchase....
Regards,
Varun

In my case, it's Vodafone also, but is in Western Europe.
My concern is that i have exactily the same problem in my present phone (Sony Tipo Dual) and it's the main reason (along side the big improve of speed and etc) for buying this phone. At the present, people call to me and they say that phone answers occupied (no network signal) and i look to the phone and it shows top signal strenght. I'm beginning to think that dual sim phones with android have some limitations (maybe antenna limitations).

thats true it should never occur, i think its implementation problem, android its not mean to be for dual sim phones the solution for dual sim on android its a samsung workarround, it should not be buggy but has some problems it does not make the phone unusable for me, I don't get coverage all the time, I travel from city to city and get poor coverage all the way so i think its not a big issue since it happen just a few times.

Hi Sriram,
My problem is very similar, Vodafone on either sim slots gives network problems, and Idea on either sim slots works fine. That makes me think that the problem must be hardware / software related to Network type. Its EDGE2 for vodafone and GPRS1 for Idea. What is the network type of your sim cards?
Phone defect.. Not related to Sim card

I use idea in the first slot and BSNL in the second slot. The trouble occurs with BOTH SIM. Earlier I used idea -Vodafone pair, the problem was still there. I live in am area where all operators have weak/varying coverage. Airtel and aircel have already been reported as showing same problem. All the users are affected with this issue, so it is clear that this has nothing to do with the operator, it is a fault of the phone either hardware or software. I think you have idea Sim working fine only means idea network is better in your area and may not need frequent network cell changeover. (?) And another fact we can see from the reports is, that, almost ALL THE COMPLAINTS have been reported from INDIA where the model released is the duos.
S4 Mini Network issues.
I too have a S4 Mini for less than a month and I am also facing network issues. One thing to notice is that the sim with internet doesn't have issues. Irrespective of which slot it is in. Currently I have Vodafone IN on Sim 1 and Airtel on 2 (with 3G). Airtel works fine and Voda has issues.
I did speak to Samsung care, they were very nice, however the problem wasn't solved, I have been adviced to go to Samsung service center and get the S/w reimaged.
I still haven't done that, however what I did was to reset the phone and while I was browsing on the play store I got a software called "Where is my Signal" by Grey Boy. For some reason I feel it is working fine now. I have not had any issue from last evening, baring one time when I was on a long conf call for around 150 mins today. else it has been working fine and receiving calls on both sims too.
I had used this software to refresh the network once, it has helped me, not sure if this is going to sustain but for now it is good.
If some one else also has this software installed and is finding this to solve the issues kindly post the same on the forum and may be helpful.
Will repost tomorrow again with the status.
BTW I agree to many opinions in this thread that Samsung should have done some testing or atleast after many of these issues coming up needed to provide a patch upgrade.

I had tried three apps of that kind: where is my signal, network booster(marcstealth), and network refresher lite. None of them could overcome the strange problem of this phone though at first they seemed to be working. Another question is, how do we know when to refresh network? If we know the signal is lost, we can restart or do something like that. Then there is one more issue: sometimes it shows good/full signal strength, but when try to make a call, will realize that it was false! I made to run the network booster app run when signal is low, using tasker app -but we are not supposed to live such a life using this celebrated costly handset.
But one thing in your post is of much importance. DID THAT RESET WORK? You haven't said much about that.

The reason for reset was to ensure that none of the softwares I had installed were causing the issue. The reset didn't change much compared to the way it was earlier.
Some observations of when the problem actually happens (again this is my observation and doesn't need to be the same in your case)
> When I am on a long incoming call on the sim which has Internet.
> Noticed that short calls don't impact the network.
> If there is a call drop imm after you receive a call.
I am planning to get the phone firmware re-imaged from the service center however I will need atleast 10 more days to do it as I am currently in a different city and I am not carrying the invoice copy.
BTW Rajesh, did u get any response from the CEOs office?

Hi guys... Im from Panama and i have a question let tell a little background
Here in Panama we have 2 providers that have LTE and uses band 28 this is why i bought my zenfone from taiwan with band 28 reception... this is the problem i put my sim card from one of the provider and guess what didnt got LTE and they told me is becuase is my phone that is not allow in their network (they are selling phone which is LTE ready according to them) But i friend of my put his simcard of his samsung S6 from the second company (uses the same 28 band) and my phone got LTE rightaway... So is somthing the provider can do to stop phones coming from outside getting LTE? Right now my phone is getting HSPA+ that is H+ but nothing else
And in the screenshot my phone is detecting the network which is the first LTE that you see. The second LTE with Forbidden is from the other company from which my friend have his simcard..
Thanks for the help

So is somthing the provider can do to stop phones coming from outside getting LTE? Right now my phone is getting HSPA+ that is H+ but nothing else
And in the screenshot my phone is detecting the network which is the first LTE that you see. The second LTE with Forbidden is from the other company from which my friend have his simcard..
Thanks for the help

mmm, should you probe further to your Service provider on why it is not allow, could it be that your version was the TD-LTE? which only china has? they use difference accessing method.
the possibility of SP locking the network base on phone is rare as they need to spend extra server to cater for such banning and this does not goes into their profit and Ike customer in general. It could also be that your sim card does not have LTE function. this function is stored in HSS ( HLR) where all your services are known in the network.
Check further then post here. seem to me it is more of your sim account issue.
i post tomorrow im going to talk to my provider and hear what they have to say
Thanks for the interest

Hi good evening , well i came back and I talk to my provider this time the guy told me that my phone should work withouth any problem since it uses the same LTE band as they do which is band 28. He told me that aparently they have to activate something in their network in order for my phone to get LTE signal so they will be calling me tomorrow to tell me if I need to do somthing else. I ask him if i need to use a contract or if prepaid work too. And he told me that it also work with a prepaid service. He told me that my simcard is LTE ready and should not have any problems but told me that they will investigate. Also they dont use TD-LTE.
I will post a soon as I have the answer from them

dont trust your telecom, some truth are not allow to tell customer about, i work for 7 years for 2 different telecom.
if your phone is TD-LTE, you can never connect to your network no matter what, just see it as a door with a wrong key
if it is FD-LTE, it is most likely the settings on your profile is not provisioned, the Customer service may tell you they see it is up but in fact the system that they are reading the data from MAY not be unified with the back-end servers.
It may also because someone in-experience have wrongly provision your SIM profile.
Lastly it could be then handset is faulty with LTE service.
the best way is to call up the telecom with another phone and proposed a testing right when he/she is attending to you. ask them to forward the testing time/ MSISDN to the supporting engineering for wireshark trace. they CAN straight away tell you what problem you encounter.
you are at least someone in the forum that listen and understand truth. some others in another part of the forum are stubborn as hell..
hope you gotten the FD phone and it works for you.

Thank you very much for all these usefull information you are giving me that you gain from your expirience I really apriciate all your help and kwoledge and this will help me explain my self better when i have to talk with them.
I came here becuase there a lots of thing i still need to learn about telecomunication and bands in general (Im actually studing medicine but this calls my attention)
Well i im sure that I got a FD phone because with the second telecom (the one that my friend uses) my phone got the LTE right away so im sure thats not the problem and becuase it got LTE im sure that my phone is working all good.
Since the phone is FD then the most like thing is happening is that they havent afiliate the services correctly (that what the guy from the telecome told me) and that technicians will set up that in their side. They will call me tomorrow and tell me whats happening.
He also told me that aparently there have to be a second registration of the data service which is the one for the LTE that hasnt been done and this could be the reason of the problem.
The only thing is about the testing you you are telling me. Let me see if a got it right. Tell them to foward the time/MSISDN (its the phone numer) to engineering to wireshark trace (this is for looking that the connection and the setups are correct and the case they are not then look where is the problem if in their side or my side)
Again thank you very much. Really apriciate your help and im came here to learn and maybe some else with the same problem have the answer here
Good night

let me put it in this way
1) call up your telco and during the call,tell them that you will be performing a test for packet transfer on your phone now.
2) just try to manually connect to their LTE network by search.
3) let them know the time range that you are doing this (eg. 14:00 to 14:05)
4) get them to let the back end engineer do his/her work tracing > SGSN signalling > DPD context.
5) wait till they come back with you on the details why is it not working for you.
the handset send a signal to the radio (UTRAN) and request a data service (LTE), in this case it the radio will forward this request to the SGSN to S Gateway( just take it as signalling module), if everything is okay, it will inform the UTRAN ok to set up tunnel (in layman context, it is the traffic medium) > so P Gateway will directly link from user UTRAN to it and out to the web via PDP context.
hope this is not heavy for you, in between there are firewalls which the network engineer is able to pick up where the data is dropping for your case.
oh i see that you are going to be a medical personnel, all you need to know is that radio are everywhere and there are some instrument that is using certain band of frequency which will interupt (crosstalk) to your instrument.
the normal cases are WiFi band as it is under free band and medical usage.
For cellular, it does not matter. the reason why hospital ban it in sensitive area is because folks in the older days are using analog signal for transmission (ASK,FSK,PSK) these are to determine the data status of any radio instrument. however nowadays, we no longer use them and systems are all digitized. so it doesnt matter if you broadcast radio in sensitive room because we are using higher tech like QAM64 etc.
lastly the reason why medical still insisted that no radio in the sensitive room is all because... changing of something might affect something else, even if they know what i said, they worry that other stuff might complicate. look at Airport during flight, it is the same reason, handphone can switch on during flight but they say no. its the same reason.
The top management knows nothing and the engineers is reluctance to set things right, too much work to do.
you can read more into those, i know pilot also need to learn about these too!
hi good night im still waiting for them to reply so i think they will call me on monday. When i contact them ill ask them to do this test you are telling me and ill get back with you as soon as i have results.. Thanks and have a good night
hello a came back and with good news. The lady sold me the wrong sim card and they also had to activate LTE services. Now everything its working great thanks for the help sooty84.
Right now im getting 25Megabites pes sec down 20 megabite up i think its because LTE network is new
I think this can be mark with resolve
Hey great! glad to help
Hello every one I just got new sealed op3 , the old phone was Htc one m9 plus , I used to get 4g connection everywhere .
Now after using op3 I never get 4g connection I only get H sign means 3g ! .
Here some info
I have the correct info for APN and the network is "zain jordan"
Same sim used to get 4g
My mobile model is A3000 , and software is oxygen 3.2.7 Android 6.0.1
I checked my mobile on gsmarena for the frequency and checked my operator frequency and they match (2100) should work !
I contact OnePlus fb page they didn't give me straight answer.
When I go to cellular network setting and search manually I only get 2g and 3g networks for the 3 operators in our country.
What's the problem and what can I do ?
The cellular customer service asked me a simple question , if you put the sim in another phone will you get 4g ?
I said yes
They said : your phone problem ...
Help please XDA
I wish I had an answer to your exact issue but I do not....
However I had a similar issue on US ATT. Put the sim in never got 4G/LTE only 3G and I went to ATT thinking a new sim would fix issue. It did not.
So I said what the hell, left the sim in and did a factory reset of the phone. When it came back up I have 4G to my surprise. Prior to that I changed APN, had ATT give me a custom APN and reset APN on their end....no luck. Factory reset did it and I did not want to do it since it would wipe my data....but finally doing it worked.
My $0.02
Are you with AT&T? If yes look online and you'll find guides and hope to get 4G.
Have you tried restarting your phone? It's stupid but I couldn't get 4G before I did.
As soon as I got my new OnePlus 3, I was not getting 4G in my region either. I had just the same problem as you.
First I got in contact with my carrier, but nothing they could do, as they said the problem was on my end.
After messing around a lot, with all possible network and APN configurations and not getting any results, I got in contact with OnePlus customer support, to no avail either, as they could not find any explanation if not for problems with my carrier.
And then, one of these days, no update or anything relevant at all, it just started showing the LTE icon. The phone did not receive any updates in the meantime, I did not change any connections settings, literally nothing on my end changed at all.
The problem just fixed itself it would appear.
I had the same Damn issue. Make sure the writing on your box's label is in English. I finally figured out I had the Asian version of the phone. Was nit compatible with usa 4g lte bands
Try entering:
*#*#4636#*#*
in the dialer. Go to Phone Information and make sure the preferred network type is set correctly.
When I received my OP3, it was originally set without LTE.
Guys the problem for me is my device model is a3000 and not supported by my carrier frequencies .
I didn't know about this and I must get a3003 .
So it's dead end . That's what OnePlus told me.

Not sure why Oneplus sended you a A3000 then. They should replace it at their cost. Not sure what your local law is.

Where did you buy it from?
If you are not able to get it replaced by the seller, I am afraid that it will be curtains for 4G. No point in blaming OnePlus if you have not directly bought it from them.
Go to "SIM Cards" settings and Choose "Preferred SIM for Cellular Data" as your 4G SIM.
If your 4G is VOLTE, it should be selected as preferred Data Network in order to get network.
