[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

[Q] Full signal, cant make calls, no internet access

Hi Guys.
So received the phone on Thursday, Friday I did a sim swap from my normal sized sim to a micro sim. I waited the whole day but the phone didn't have any network access.
Today when I woke up I I switched the phone on hoping that everything will be fine, thinking the simswap just hasn't gone through yet, still no network access. I took out the swim from the phone and switched with my ipad, the sim was working in the ipad, and the ipads sim also didnt give the phone network access.
In the top right corner it shows full bars in grey, cant make emergency calls or anyhting.
In the about section of the phone, I have ALL the details present, baseband version is there, kernel version is there.
In Status section, network is unkown, signal strenght is -83 dbm 15 asu, network type unkown, service state is out of service, and the rest is also present.
I thought the phone didn't properly register to a network, so went into settings - wireless networks - more settings - mobile networks, but it gives me a insert sim card message.
The phone is reading the simcard fine because it asked for the PIN when switching on.
When trying to make a call I get, it says "Not registered on network"..
So what am I to do? Vodacom can only pickup the phone and exchange it on Tuesday, so was hoping that this might just be a software issue that can be resolved by a flash.
I have tried resetting / hard resetting the phone numerous times.
Its the Note 2 N7105 LTE Version
Any help would be highly appreciated.

Great thanks.
I tried this but didn't solve the problem. I am using the same sim that I received from the carrier with the phone they shipped.
I have played around in the menu however, maunally setting the band and so forth, just restarted and started receiving sms, so basically if not for your post I would not have solved this.
Thanks

I have isolated the problem.
In the service menu - UMTS - DEBUG SCREEN - PHONE CONTROL - NETWORK CONTROL - SERVICE DOMAIN
There are 3 options
1 CS + PS
2 CS ONLY
3 PS ONLY
CS seems to be for making calls and sending smses
PS seems to be for data connections (When this is selected, the bars are replaced with a circle with a stripe through)
I Could be wrong with the above, so anyone with experience please shed some light
Those 2 work seperately, but when CS + PS is selected, none of them work? Very odd, anyone know what the issue could be?

anyone?

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.

can't find signal

hello everyone
so i've recently bought lg g3 phone model LGLS990
everything works just fine until i go into mobile networks and change the preferred network to LTE
when i do that i lose my phone signal and all i can do is emergency calling, it's like there is no sim card inserted anymore
and when that happens i can't even change the preferred network to gsm again
but before i've done that i could've used phone for calling and messaging and internet but internet wastes my credit tho i've got a data plan and it's way too slow
i think this is related to my threat each time i turn on the phone a dialog box appears says: "hands free activation contacting network"
a couple of seconds then it fails and there is an option that says activate when ever i click it, it tries to reach my mobile network provider i suppose but then it fails too showing this message: "Sorry - we experienced a system problem during your task. please dial *2 from your Sprint phone or call Customer Care at 1-888-211-4727 from another phone to complete your task."
**im pretty sure that the sim is okay since i use it on my old galaxy s3 phone and i use 3g just fine
**i've tried to change the preferred network to all of the options listed
**i bought it new but the seal wasn't on the box tho it couldn't be used i guess since the screen sticker was on it
**the one i bought it from have brought it from another country but it's not shown that the phone is locked, i've never used a phone with a locked sim so i really don't know how is it like :/
**when ever i open sim toolkit i find the network provider's name there but when i click on it it keeps loading and nothing happens
**the android version is kitkat 4.4.2
sorry for any language mistake and sorry for my modest knowledge
please reply asap so i can try to contact the guy i bought the device from and try to get back my money if it's unsolvable issue
thanks in advance

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.
