[Q] Sim card or Phone problem ??

Hi everybody,
I have a big problem with my phone (or with my sim card).
Since 2 days, and without touching anything, my phone has a lot of difficulty to connect the Network that I'm registered to (Orange).
I'd got some connection problems like these ones :
- "Your sim card doesn't allow you to connect this network"
- When activating the 3G it stays on "activating" (even if I reboot the system and pull out the battery for few seconds)
- Non-send messages
So I decided to wipe all data and reinstall. It worked…but…the next day it restarts..!!
Do you think it's caused by an app or by rooting the phone with xtc-clip ?
My specs :
- S-OFF
- Rooted
- RUU_Marvel_S_HTC_Europe_2.13.401.2_Radio_47.23a.35.3035H_7.53.39.03M_release_225747_signed.exe
PS : the RUU has been installed with the sim card inside the phone of course.

Installing ruu with sim in shouldn't be a problem.
Easiest thing would be try another sim before deciding what to do next mate.

Thanks for replying.
In fact my phone network works again since I've created the topic but I don't know at all how ..
I've tried my girlfriend's SIM yesterday but it is a blackberry one and I don't why my phone doesn't accept it to register .. I will try again or use a friend SIM this week end.
BTW does your 3g connection make about 5sec to be activated ? Before the problem appears in 1/2 sec I've got the 3g. Now it's more, but it works.
This is not an APN problem 'cause they're all OK and for messages it's not a problem from message center since it's OK.
So I am always wondering how the phone could have this behavior without any changes.
If it makes the same again, I will call my operator to know more about it and will make a feedback here.

It could well be network/operator related maybe they have a problem.
Anyway main thing is your back up and working again.

The problem isn't resolved unhopefully... It doesn't work at home .. Sometimes yes, and the rest of the time no network (even if I got all the bars of the network and the Edge Logo) and I can't do anything.
I called the operator yesterday, they say my SIM card was defective so I went to the operator's shop and they changed the SIM card.
But back at home, it doesn't work again .. And now I'm at my job's office and it works again ..
So I conclude that there is a network problem in my block of flats ?
I will call back them tonight to see what they tell to me and will make a feedback here.

Also I tried to swap phone, the same problem with my old Sony Ericsson.
I put my SIM in my girlfriend's Blackberry (network used to work for her), and it does'nt work. Then when she puts back her SIM card, she had no network as me...
So could it be a hack of SIM card to prevent you having network at home ? (it could seem a lil bit paranoiac I know ^^)

I don't think so mate.
More probable is that the mast that provides data that is closest to your home is at fault.
I would just make sure to report it and I'm sure others will have issues, so your provider should investigate and provide a solution.

I called the network provider, they say they will call me tomorrow for me to talk with a technician.
BTW my girlfriend called them earlier and they say this is a problem due to the residence.
I tried to ask them if there is a problem with the mast, they said it seems to be normal and network works well in my area...
But the network is fine out.. In the appartment it works about 10/15mins per hour ...
For the "SIM Hack" suggestion I told you, do you think this is possible ? (I doubt because no problem out ..)
Let's wait and see ! If you have any suggestions, don't hesitate !
Thanks for the support though !
Edit : always all the bars of network and E logo just sending, not receiving when it doesn't work.

Maybe your building is a blackspot meaning signal is not passing through happens to me indoors with wifi.
And where I live in a small village I can't get a good data signal indoors.
I have to turn off 3g altogether and opt for 2g only as it gives me better call signal.
But if I walk for 10 mins towards town I can switch to 3g and its perfect.
I would just wait to speak to the tech guys and see what they say.
Oh and forgot to mention my operator reduced my monthly bill due to my poor signal, haha.
Good luck hope they sort it for you.
If not try a different network sim just as a test.

The strange fact is that it used to work perfect in the building.
There are problems for about 4 days now.
When I forced 3G using "WCDMA only", it seems the signal was better and not blocked on E/G.
And now I turned it back to Auto and it works .. I don't understand what the **** is happening... !! It comes back to 3G/H.. but sometimes it fails again ..
I will wait for the tech guys, and if it's not solvable I guess I would ask for a commercial act such as yours !
Moreover this week, friends will come so we will see if they've got network (I believe they're at the same network provider, no luck ^^) .. !
Thanks for your support again mate, really appreciated !

My phone just started doing the same thing. Its a stock phone.

Finally nobody called me back but the network came back so no more problem now.. How ?? I simply don't know .. Good job "Orange".. !
Thanks for support though

No network issue after repair

Hi there,
I recently sent my phone back to HTC because my volume button was stuck, which resulted in it not being able to boot (as it always went straight to recovery). They repaired it, and after three weeks without my phone I know received it back. They 'replaced parts and did a software update.'
Problem is, now I have no mobile network connection. The phone recognises the SIM fine, but no signal and search networks results in "Error while searching for networks."
I'm blaming the software update HTC did, so I send them another email. The thing is, I don't want to send it back AGAIN, I had the phone a full 2 weeks before it broke and haven't been able to use it since. Is there anything you guys can think of that doesn't involve rooting it and losing my warranty (which I will probably need now)?
Thanks a bunch

Hello,
have you tried to switch between the network mode; only WCDMA or only GSM? (Settings->Mobile Network->Network Mode)

Thanks for the reply. Yes I have, no effect. One other weird thing I have noticed since first posting: at the about -> Phone Identity screen, the phone number does not match my actual sim phone number. It reads the SIM fine though, as all my SIM contacts are available.

Could you use/try another SIM Card to check its work with a different one?
Is WiFi working? Any interruptions druing a regular call?

Regular call is impossible, as I have no cellular network at all. Wifi works fine. I am currently unable to try another SIM, as I'd have to cut a microsim out of a regular one and people around don't want to have their card cut up.
The sim works fine in my old nokia though, so I don't think that's the issue.
I'll try to find a friend with an iPhone 4 to try their microsim, but I'm not really counting on it.

No service - HELP!

Hi Everyone.
Stock O2 ICS- rooted - bootloader unlocked
I've recently bought used HTC One V locked to O2. Problem is gsm service never worked for me.
WiFi, Bluetooth, GPS are fine but emergency call only.
I've tried different sim, 2 custom roms, hard reset and no lucky.
Under mobile network setting I cannot swap between WCDMA only - Auto - GSM only, it is sticked to WCDMA/GSM Auto only
When push *#*#4363#*#* Cannot change network mode too, WCDMA preferred fixed only, if going to radio band selection cannot choose any (Automatic, EURO Band etc) just got message "Set [automatic or any] Unsuccessful.
What is weird, When I turn mobile data on with correct APN for my provider (currently giffgaff) I have gprs running and can send and receive data, but with my other phones I had before my service has been alwaysfast as 3G and HSDPA, not "G" like now.
Please see below my screenshots, I've checked my mobile network with many apps and there is what I've found

Ok this may seem a very stupid question but it happened more than once. Are you using the little piece that covers the sim card? That has contacts in it, without it there is no signal

If you still have warranty, run a ruu so it goes back to stock, and take it to the HTC centre. If you are lucky they will recognize it as hardware problem and give you a new one. Remember to tell them it never worked, and if they ask about root or stuff, you don't know about it

No I don't have a warranty (it's second hand and a have no seller contact anymore), otherwise I would not asking here. Looking for somebody who solved this, if.

Help 4g

Hello friend, i bought a new m9 and when i activate data mobile i have only 3g , i tryed factory reset, to setup my network,
I rooted my phone, installed custom room.. still no change.. anyone can know why ?

Well maybe you dont have great 4g signal in your area? Or change apn.

As stated already , the signal could be weak in your area. Type in the dialer key pad ##3282# and you can also look to make sure all the bands are enabled on your device. I don't see why they wouldn't be though. A handful of users have stated bad connectivity with the M9, but that's on the sprint network I have been reading about.

at ##3282# it say only OK.. nothing about enable bands and i tryed sim of my friend (vodafone 4g) he have m8 and 4g working... on my m9 doesnt..

I have same problem with my M9+. In Manchester Area UK
I had perfect 4G with my old M8 but with new phone only 3G!!
Let me know if you get any answers. HTC and Vodafone couldnt help me either.

Check access point names, make sure only one is listed and selected.
Go to networks and search for network, click automatic.
Open the connectivity selection and make sure that the scalable option is chosen (2g/3g/4g)
Are you using one Base with the wrong firmware? Make sure they match up.
Find a friend on the same network or shared network and see if they have 4g in your location.
Test the sim in another phone.
Call network to check for issues in your area and or if there is an error against your account, may need a new sim if that one is old.
Test in major parts of the city center next time you're shopping..
Perform a speed test to see what speed you're actually getting, hspa is up to 20mb, 4g AFAIK is around 60mb, I've had 48 before. Anything over 20 could be considered 4g, you will very very rarely see a 3G tariff go over 19mb, which is the most I've ever seen.
Good luck.

I have the same issue with the M9. Couldn't find an answer for this problem. Even tried opening lte bands as listed here but no luck.
The thing is that I used to get LTE where I am now, went on long holiday and can't get it to work again so no idea what's up.

I tried my sim with my wife's iphone and i got 4g without any problem. It's not a sim issue. Whatever the problem is, it's with the device (hardware, software, settings). I remember it also took me a few weeks after getting the M9 to get a 4g signal, but then one day it just appeared so there's that to add to the mystery.

Reset your network settings mate, set to manual then back to automatic.
Make sure you actually catch the network on manual first before manual. You will find it, it's just a case of going through the motions.
Also click menu, reset to defaults in access point names.

1. How do you "reset network settings"?
2. set to manual - you mean in 'Network operators' menu select 'Search networks', select my network, then go back and selecting 'Select automatically'?
3. What do you mean "just a case of going through the motions"?
4. Should I reset APN at the last step or at the beginning?
I'm trying to understand your steps as clearly as i possible can because this no 4g issue took a lot of time and effort from me and it still doesn't work. Any help is very much appreciated.

I am trying to help you.
There are no steps it's just a case of trying everything to do with the network. If what you say is true and you've literally just had this issue occur out of the blue then it has to be a difference on the handset, especially seeing as you have tested the sim in another phone and it works.
Reset to default is with apn, doesn't matter when you do this just reset them, make sure it's checked and cycle mobile data on and off.
Clarify that your device is set to 2g/3g/4g within network mode (I believe it's called)
And I was referring to setting network selection to manual within mobile network settings, then choosing your network, then researching and selecting automatic.
The path is: settings / mobile data / network operators / search networks, wait for yours and select it, cycle mobile data (turn off then back on) if that doesn't work, switch back to automatic.
Reboot your phone after making changes, perform the full shut down method instead of the restart or power off methods, it's power and volume up AFAIK, hold for 10+ seconds, might be 15.
Going through the motions refers to checking anything and everything which influences the network, one of these setting will get it working..
Might be seen as overkill but a factory reset (if it's not been tried already) good luck.

I know you are trying to help me, and I very much appreciate it. Truly am.
I tried doing all the steps you listed, but no luck. Even tried at some point to force lte only in 4636 screen but that resulted in no signal at all. Trying to manually select a network in that setting only gives me the other 2 networks that work in the area but not vodafone which is what I use.
As a complete overkill I RUU earlier to the new 2.11.617 firmware without signing into my google account or restoring anything, and still no lte. What I did saw however, in the select network screen, was that next to my network, it said 2g/3g and next to the other 2 networks here it said 2g/3g/4g. Obliviously I can't select them as it's a vodafone simcard.
I added here SS from LTE discovery app while i was on 'lte only' mode. You can see signal is there but it cannot connect.
Any wild ideas or suggestions? I'm opened to try almost anything

Just out of interest, have you tried a different sim card? I know you said that your sim worked in another phone but I'd still be tempted to contact voda to get a new sim and to see if everything is set up on a network level, you may have to tell via that the issue is persistent in different phones or they may make you pay for it.
Also, might be something to do with the association between your phone and your sim. I once had a sim that blocked my missus, she could call me but I couldn't call her, no active diverts of any kind, I could call anyone and they could call me, got a new sim and it was sorted. Very strange, but anomalies like this do occur.
Have you got any mods or are you at stock at the moment? I know you said ruu. Oh and lol click thanks BTW.

Well the thing is that my wife's sim card in my phone only gets 3g. On her iPhone it's 4g. My sim card in my wife's iPhone gets 4g. On my phone only 3g so it seems like a very specific problem with my device.
Shortly after ruu I installed viper 3.5 without any mods..
Can it be that my device is somehow blocked by the network towers or something of that nature?
Maybe a hidden setting somewhere that blocking the phone's 4g capabilities? This is getting ridiculous..

No worries fella
If you've already tried another sim and it's still not happening, the firmware matches the rom, your sim works in other phones with 4g. Then I'm really not sure mate..
Give Lee droid a whirl that's what I'm using at the moment.. A simple but great rom..
I'm pretty much out of ideas now, if all of the above has been checked then it's something that I'm not aware of.. Sorry mate..
for the record it is a weird one, something should have got it working by now..

I can't return the device as it was bought in the states and I live in Europe at the moment.
I think I will try to change my sim card for a new one just in case, and will change back to stock 2.11.617 for a couple of days to see if that can make any difference.
Will post an update if i will have one.

Yes it would. He probably bought a cdma and has to have the correct bandwidths unlocked.

Occasionally unable to receive or make calls on XZ2c

Hi!
I am occasionally unable to receive or make calls on my XZ2c. Specifically, sometimes (say, every few days) people report to me I cannot be contacted although I am in a place where I have good reception. And, in such cases, if I try to make a phone call myself, I cannot. Even more specifically, the caller in these cases hears no ringing and no typical carrier voice message that my phone is off or that I cannot be contacted for the moment; while, when I try to call, nothing happens for a few seconds and then the phone app stops stops trying.
A restart always solves the problem.
Also, it may be the case - but I am not sure - that this happens after the phone has briefly lost reception (for example, in my office, because I exit the elevator, or in my home, as I have a blind spot in the courtyard). This seems to me to be the case based on a few observations but, again, I am not sure about it.
Otherwise, the phone works impeccably, but since I missed a few crucial calls recently this has started to bug me. (Needless to say, my two mostly retired phones, the XZ1c and the OG Pixel, do not have this problem when used in the same environments.)
Any suggestions, please?

I have the same issue - and reboot suddenly resolves it. I've tried to ask over Sony forums, but no reply yet. It bugs me also, but it would be quite hard to report it to Sony service center, as I cannot reproduce the issue myself. (although I think they are aware of the issue) It's a bit strange that my XZ2C has reception problems where my Z5C used to work...

It would help if you would report what carrier you guys are suffering the problem on and whether volte is enabled and if you have tried more toggle options of which networks to fall back on to make sure you receive calls, there is a way to manually set it to fall back all the way to GPRS 1.5 G manually haha my carrier supports that and i was once deep in the forest and still recieved a 1g call haha. It is not enough coverage on weak signal for 2g or edge calls.
In some cases inside big city where they ONLY have either LTE or WCDMA ON THE NETWORK, then YOU MUST either force it to use LTE only, or wcdma only. That way it does not jump back and forth and miss call. Some big cities i set it to lte only and even in basement or in skyscraper it is always full bars. So it just depends which tower types are in your home area.

It's Telenor Hungary, no VoLTE or other "magic" involved. There was a previous thread, which discussed the same issue. Actually I posted it to talk.sonymobile.com also, but please see the attached screenshot - it shows the actual issue. Telenor Hungary shows up as "emergency calls only", while Telekom HU and Vodafone HU seems to be fine. Sometimes switching airplane mode on/off solves the issue, sometimes it's a reboot which makes me able to make/receive calls again. But forcing 2g/3g/lte does not have an effect for me.

If this is the case, it is the SIM cards identification is not consistent to the network tower. Maybe the carrier has updated sim card version if you ask them. If it is emergency calls only logically its the network not authenticating your account based on sim card. It may be sensitive to the phone hardware. I have heard some people on other phone models hadd to ask carrier to provide even old version of their sim card instead of new ones. Try that.

If this is the case, it is the SIM cards identification is not consistent to the network tower. Maybe the carrier has updated sim card version if you ask them. If it is emergency calls only logically its the network not authenticating your account based on sim card. It may be sensitive to the phone hardware.

Thanks, I'll give it a try today and ask them to replace sim card. Hopefully it will solve the other appearance of this issue also: whenever I have full bars and talking (usually late night driving home to parents, in a well-covered area), audio quality degrades in seconds - at least on my side - and other party is not able hear anything I say. After disconnecting - if I'm able to do so, and phone app does not get stuck with "call disconnecting" message - I'm not able to make/receive new calls, as only the outline appears of signal strength bars. After restart everything works perfectly. Strange, isn't it?

It's Telenor Hungary, no VoLTE or other "magic" involved.

Ironically - or maybe not - I am not that far away. I am on Orange Romania. When I search for networks I get essentially the same picture -
Thanks, I will try the SIM trick as well, maybe it helps. I may even go as far as jumping carriers, in fact.

Got my sim card replaced, now waiting for the issue to pop up again. (or hopefully not) Actually the guy at carrier said my "white" simcard (about a year old) was a problematic one, replaced it with a new. I don't know if this could be true, but hopefully it'll solve the problem.

It seems that replacing the sim card solved the issue, thanks for the hint! I would have never ever thought that a sim card issue may cause such a problem.

I have exactly the same issue and have already a new sim, which doesn´t do the trick for me....any other ideas how to solve this?
no VoLTE or anything like that. T-mobile as carrier

No longer have this problem with recent firmwares. The sim change did not solve the problem for me.

Thank you for the feedback.
With the recent firmware you mean 52.0.A.8.50 on android9? Do you use stock rom or a custom rom?

No, it's the past 4 or 5 firmwares.

What an irony! After updating to the latest fw some 2-3 days ago, it's happened again, the first time in some 4 months.

Nooo... I just got my replacement phone today and so i installed all the latest firmwares.... I still have high hopes i won't be affected again.
Has anyone any idea how many phones are affected this way... Can't be all of them otherwise there would have been a flood of threads about that.
Maybe some prior models of this series...

Did you test different firmware regions?
Maybe your mobile network provider and the baseband aren't compatible (bug).
And did you report Sony that the bug is in the newest firmware?

No i've just used the original settings since i am still in warranty time
But that's why i've asked before if the others were experiencing this issue only with their stock or even with custom roms / fw.

Changing regions doesn't need an unlocked bootloader.

For that, do you mean to change the settings in the play store or which settings are you referring to?

Just use xperifirm and newflasher to apply a different region.
But remove the userdata.sin if you don't want a full wipe.
