[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

If you want help, you need to tell us more details, such as what software/firmware version you are using, network carrier, what actually happens when you get no service, if it's rooted, etc.
Basically, the more information, the better.
Anyways, I have that random no service with the Australian Optus network, even though it says on the phone that I have full bar reception. Sometimes it's just the network.

it's unrooted 1.28.707.10 sense 4

"Not allowed" suggests a SIM problem.
Either the SIM has gone bad and you need to request another one from your network, or the SIM connection on your handset is dodgy.
The SIM governs what you can and can't connect to. If it's not allowing you to choose a network then it's not reading the information from the SIM properly.

maybe the groove made by my desire s is too deep

even with the new sim the problem persists
trying auto(network) mode now
1.29.401.12 and the newest 2.17 update have new radios i hear
maybe that will fix the problem,
thats my next step.wait for the ota

same thing
exactly the same issue
already changed SIM card and anntena
but nothing changes
i have sense 4+ (i thought the new update will fix this)

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.

[Q] phone turn off when sim inserted

Hi. i have unlocked Sony Xperia Ion LT28at.Was using it for couple of months but recently phone start shutting off, first battery lower than 30% but now even with 100%. Found out that it only when tmobile card is inserted. Tried my wife's card ,the same. without card phone still works and also when I inserted att card .I also just did factory reset Like I said phone worked perfect until like a week ago.
I just make factory reset and tried to play with the phone with different sims i collected over years. It works perfectly with Orange, Play,Cingular,ATT sims, but when I put old prepaid tmobile, it is shutting off again.

Old sim's do that. They short circuit your phone, because they are old. Don't use it, or change it with a new one.

It may be so, but the same sim card work without the problem in another phones and the 12 year old cingular card does does not cause the problem, only tmobile cards. My daughter card is like a year old and it is causing shut down also.

Call tmobile and let them know about the sim problem.

Someone says that it is a "safety" measure built in the system.
I'm not sure about that though.

Ok right now I reflashed the phone with current firmware, there is no programs installed. tried old sim cards from Orange,cingular, ATT and one more company I think Play, all works with the phone no shutting down. Then I tried my old prepaid Tmobile then my daughter's and my wife's tmobile cards all of them are shutting it down within a minute. I am using replacement unlocked samsung and have no problem with my sim card , same my wife's tmobile samsung and my daughther HTC oneS. Have only problem when I want to pair sony ion with any tmobile sim.

Try to disable the PIN CODE just for a few minutes. See what that goes.

Don't know exactly what a pin code is, but just re-flashed the phone to LT28i, did not helped. phone still shutting off.

I had the same problem too.This worked for me:
1.Open your phone without sim
2a(Ice cream Sandwich):Then Go to the settings->more->mobile networks->Network mode or 2b(Gingerbread) Settings>Wireless and networks>Mobile networks>Network Mode
3:And change network mode to WCDMA only(this worked for me).
4:Insert your Sim and restart your phone
If "WCDMA only" doesn't work you can try "GSM" only.
Old thread but I hope someone else gets helped by this.

For everyone
if it still interests you, I have a simple solution that works for everyone

Please tell us!

I'm not sure at 100% that it ll work for u but i personaly tested it and worked fine
so you just have to activate the pin code on security and location setting
but the SIM card must be inserted to activate the pin code
If you never activated the pin code, then the default code must be 0000
if the phone turn off before u get acces to the setting menu so u have to
- boot without the sim
- turn on flight mode
- power off and insert the sim card
- boot with sim
- after this follow the above instructions
- reboot and after u enter the pin code turn off flight mode and see if the phone shutdown or not
- if it shutdown try to go back on setting and set mobile network to use gsm only
if u don't understand reply !
I hope it work for u

Is there any solution to this problems? Previous suggestion is not work..
- When insert sim card, the phone will shut down when try to search the network.
- The phone will not shut down if switch on without sim card
- But if the phone was connect to the charger, it can switch on with the sim card.
I don't think the battery is bad...

I just realize that, the problem is went want to search th 2G (GSM network). My area did not have 3G (the phone have poor 3G reception). So, the phone need to be in 2G mode, so it keep going shut down.

The problem is simple. The battery contacts need to be cleaned. Use a cotton swab, damp it with rubbing alcohol and clean the battery contact on both the battery and of the phone. The rubbing alcohol is safe for the metal contacts. Install the battery back and turn the phone on. This took care of in my case. Avoid touching these contacts as they're sensitive.

Amazing workaround!

Amazing! This is a great workaround. The reason is actually batteries getting faulty. I moved to 110V country from 220V and used a voltage transformer in front of adapter to charge the phone. It did something bad with the batteries. Though phone works fine when on charging- no shut down. It shuts down only when I try to place a call. Also I now charge it via laptop usb and disabled the fast charging and I think that also made batteries a bit better as phone is not switching off that frequently as it used to be. So also see how u are charging the batteries

Phone stopped receiving and making calls

hi everyone, i have a lg G7 EMW for almost two years now. as said my phone its an EMW, although I use the EM variant ROM for more than a year because of the lack of updates. never had any issues before.
some weeks ago i had to make a call and noticed it was not working, at first i though it was a cover area issue with my carrier, since it was a place a little far away.
but in the following weeks i started noticing a lot of messages saying 'a number called you and did not left a message' and them i realised that the phone actually never ringed, so i started making some tests and realised it was not making or receiving calls.
i cannot acess all the settings in 'call settings menu' it return me an error saying "network or sim card error" but my 4G internet connection and SMS in the other way, works fine.
I already tried my SIM card in another phone, It worked normal. then i tried another SIM in my G7 and it has not worked also.
i have also tried to go back to my country open rom in a fresh install, but nothing changed.
yesterday after receive a cell broadcast notification, it worked for a short period an them stopped again, so i suspect may be some problem with the network, seems intermittent somehow
have any of you faced similar issue or know any solution? is there something i can do in service menu to see if its a hardware problem?

There were networking changes, so you need a sim card that is compatible with these changes.
If your SIM was purchased two years ago, it may not be compatible.
Just contact your phone provider, whoever it is, and ask them to sell you a compatible LTE Sim card. I had to buy one from Net10/Safelink for 99 cents, because the one I bought two years ago from Best Buy for "Net10" was not compatible with the new changes. All phone service providers should have a "buy your own sim" program, so just contact them for it.

check all necessary information in phone's settings about section.
Is any information missing there or blank?

i can give that a try but i'm not sure, my LTE and SMS seems to work normal, it is only the calls the problem.
the other SIM card i tested on my G7 was from a different carrier and the problem persisted
also my sim worked normal on other phone (Moto G5 Plus)

Call your carrier and ask them if they are using VOWIFI and VOLTE for their calls now.
The phone falls back to 3G mode on calls.
If the SIM or the tower you connect to is not provisioned for VOWIFI/VOLTE, the calls will use 3G.
if the tower is provisioned for VOWIFI but your SIM is not, then the calls will fail. SMS will not fail since that's LTE already.

This problem arises when particular phone has lost phone identification numbers such as S/N, IMEI SV and mainly IMEI. if it's the case then you must try flashing latest stock firmware for you model.
