Please help, put in Sim card, shows 'no service'

Hi
I just got on at&T 8925, I put in sim card and it did not ask for unlock code, so I guess it is unlocked, I put in my sim card (Fido Canada,works in other phone) and it show "no service" can not find phone network signal.
I tried
ATT ROM 1.57.502.2 and
RUU_Kaiser_ROGERS_WWE_1.83.631.4_radio_sign_22.51.88.13_1.27.15.32R_Test.exe
radio 1.27.12.11 and 1.27.15.32
all same problem.
Can anyone help me, are these rom combinations not good? or something wrong with the device?
or anything I need to do?
thank you for your help !

Try another known-good SIM card. If you still cannot get service, then you probably have a hardware issue with the phone.

Sounds stupid, but did you make sure you put the SIM in the right way around.
You wouldn't believe how many people have not done this right.

Sounds like it's not unlocked... when I got mine it wasn't unlocked but it only asked for a code once.... just run the unlocker to be sure...

maybe to hard reset?

Hi thanks for everyone's help.
I think I put the sim card the right way , otherwise it will show 'no sim card'
I am keep trying other rom/radio; still no luck, it either keep searching or say 'no service'
I really hope it is not hardware problem.
hope if anyone has the experience and could help me
it really confuse me.
Thanks

welll this might be a little solution i read in another thread...sum times the phone will not read the sim becuz its not making enough contact to the phone...so maybe a little piece of paper on top of the sim then put it in the phone MIGHT help..if it doesnt then ur phone is jacked up =P
or
when i put my tmobile sim in my unlocked 8925 it worked and then a couple our couldnt get n e service... and i checked my brothers phone and dad and they didnt have service too... so maybe sumtimes the network will nto work for a while. or sumthing

If you go in the phone options and do a manual network search, does it find anything?

Thanks brian_v3ntura:
but I tried paper, same thing, maybe not be contact problem.
Thanks kilrah:
I tried that, it shows " cannot read setting from network, try viewing setting later or disconnect data connection and try again."
I did saw something online that maybe because the Fido sim card maybe old (about 3 years), but it did work with sth. like Samsung blackjack II. maybe Kaiser is more complicated.
just wonding if anyone have experience that old sim card may have problem with new phones.
I will keeping trying...

My SIM card is about 4 years old.
I'd bet your Kaiser has a hardware problem.

Hi, guys
I tried a friend's Fido sim card, it works, I don't what's the difference, but it is just like that, maybe I should go get a new card.
Thanks everyone.

good
as one of the boys ur sim might be damaged/old (power failure issues most likely)

yeah, just what confused me is that the sim card still work with my other phones.

Hey guys,
Long time lurker here... and I'm having the same problem.
I have a foreign (Cyprus CytaMobile Vodaphone) SIM in my Kaiser. A couple times over the last few days I was getting the "no service" but if I reset (turn on/off) the device it was fine. Today I cannot get service on it at all. I tried it in an unlocked 1G iPhone and it didn't seem to work either.
I thought maybe the SIM is dead, however when the device it's in starts up, it asks me for the PIN set on the SIM card. I enter the PIN, and it unlocks the SIM. How could the SIM be dead if the PIN authenticates? However, when I put my regular Canadian Rogers SIM in, it works fine.
Where it usually says "Searching.." on the home screen, I once got "Denied, searching.." but I haven't been able to reproduce it.
Any ideas? The provider doesn't have a local roaming agreement, however for the past year it has always registered on the network and allowed me to check balance and send text messages.
Is it most likely a dead SIM or blocked by Rogers? I'm doubting the blocked part, but the successful PIN entry is what has me baffled...
Thanks!
Chris

Ok different SIM card also from Cyprus Cytamobile in a SE w810 does the same thing. Is Rogers seriously all of a sudden blocking these? There is no local roaming agreement, however I would always get the Rogers welcome text's and even be able to check balances. I've been doing this off and on for 4 years...
Anyone ever heard of something like this?
Thanks,
Chris
P.S. Sorry, getting a bit off topic but I thought the initial problem was related!
EDIT: Ok, I can also see all the SIM contacts and SMS messages stored on the SIM.

I also have the same problem with my tytn, I have a bad feeling it is hardware If you manage to find the problem please let me know. I have tried the paper thing and also all new firmware and OS nothing helps

Try setting it to GSM only (disable 3G) and see what happens.
To do that go to Settings->Personal->Phone->Band->Network Type=GSM.
If it works then, you might want to read this thread: http://forum.xda-developers.com/showthread.php?t=419803

...really need help, 24 hours to go!

Hello everybody, I'm writing you from UK, where I bought a second-hand G1 (absolutely perfect!!! really good). The phone is T-Mobile branded and factory-default cleaned. Once I got it, placed my italian H3G sim inside, and (of course...) it told me that it was locked. I purchased a key (...I know may I could do without it... but very few time to spend, these days) and it was succesfully sim-free. Then I reebot it, and start the acrivation... that doesn' run!!! I insered the correct APN parameters, I also tried with a UK O2 and Vodafone sim, but, problem is that the gsm segnal level (small icon on the top with 4 vertical bars) is not giving signs of life, and it has a small "cross" on the left side. Of course I can't get the registration... I can't get the line!!!! why does it happen??? all the sims are correctly recognized (ask for the pin and the "no sim" messages and icons are off), but no way to go over...
Please, help me in any way, just 1 more day here, then I'll go back to Italy... far from the shop!!!! HEEEEEEEEEEEEELP!!!!!!!!!

If you type:
reboot
and press enter. If the phone reboots you can have a chance, if the phone does not it means its on a updated version which you will have to downgrade. While downgrading i recommend going up to Rooted versions of android. Although you might not need it.
You should look here:

and/or here:

You can get through your problem, if its just the registration. by simply following a few of the instructions in the first link combined with some of the instructions in the second link.

@elmejor: He didn't even mention rooting. His problem is he can't get his phone to associate with the networks on his sim.
@tony_m78: You should probably post what apn settings you are using. Also, this is NOT A DEVELOPMENT ISSUE and should not have been posted in this forum.

thanks gor your answer.... I have been to those links THOUSANDS of times, within yesterday night and today... but I really can't get a solution. I can't go over the "error connecting to server" page :-(
The worst problem is that I really don't have time NOW, but I'll have it at the end of the week; I know I'd get a solution, working on that... but really I can't. But whay do you think about the absence of segnal? is it normal?!?
Tomorrow morning I'll find the way to buy a T-Mobile original sim and try to see what happen. . . . . . but that's strange!!!!!!!! not normal... i insered a correct code (generated from the IMEI), the answer was "unlocked", free for others carriers.... BUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU!!!!!!!!!! :-( tic tac tic tac. . . ..I don't have time!!!!!!!! :-( nobody experience this strange problem?!?

...I don't think the problem is the APN, I set the correct one (from Wiki) for H3G Ita and for O2 UK (these are the sim I tried with); the problem is that the segnal is ZERO, like the sim is not present... BUT IT IS, it ask me for the pin and accept it....

Can you manually select the network to connect to? Settings>Wireless controls>Mobile networks>Operator selection

Are you sure radio is working on this phone? Maybe it has some physical problems (like bad gsm chip)... Or - maybe you have sim cards not acceptable in UK.
Try with T-mobile sim first. If not working:
I would try to factory reset device some times, if it don't help I would try to reflashing it (firmware and radio). But in your case I think you should ask about this situation in shop where you bought it (if you have warraty) first.

Data plan?
I had a similar problem when I got my APD1 phone in the US. When I returned to the UK, I put in my Tesco SIM and the phone signal strength icon had an 'x' indicating not connected or no signal. Eventually I used my home wifi to activate the phone. After the phone was activated, the same SIM was able to connect and the signal strength icon worked normally.
BUT, it turned out that all I probably needed to do was to have a SIM with a data plan (which mine didn't at the time) <<BLUSH>>
Have you confirmed that your SIM has data turned on?
Of course ensuring that the APN settings are correct is also necessary. (But it sounds like you did that)

Nexus isn't finding network :mad: Help is needed

My Nexus was on 5.0.41, all working sweet, then it stopped "finding" the network. No update, flashing or anything was done prior to the problem.
I tried a SIM from another provider, but still - the "No Service" is written on screen, and when I try to search for networks, it says "Error searching for networks".
I then tried the following ideas (nothing helped):
- Reflashed the Radio image.
- downgraded the Radio image.
- Upgraded it again.
- Flashed the Stock ROM (unrooted and rooted).
- Flashed CM5053.
All was done with wipes as needed.
Any suggestions will be more than welcomed!
Can the device just get bricked like that? with no reason?
It sometimes identifies the SIM's provider (Orange for example) but always with No Service.

It sounds like your SIM card slot isn't holding the card in tight enough to make full contact... try putting a business card, cut down to size, between the SIM and the phone's frame (note, not the contacts side, but the back side) to force the SIM down onto the reader tighter.
If that does nothing, not sure what to tell you?

it didn't help

I'm Italian and I have the same your problem .. I only work in 2G GSM'...ve tried to see if you do so?
I opened another tread here Forum

You need a new SIM.
I just had this problem on Friday. The SIM some how falls of the network and your provider network will not allow it to reconnect.
I can't remember, but if I am right Orange is owned/owns by T-Mobile. Hence they have the same network.
The puzzling part about this is why it happens. This is the second SIM I have gone through with my N1, I also had one go with my G1, my sister bought that G1 and the SIM went out again. My mom bought her G1 same day as me and hers has died once. My friend has a MT3G and his has died two times now. I find this extremely annoying.
I tried every suggestion on the internet for repairing or troubleshooting a SIM. It is a waste of time. Well, everything short of dropping it in isoproply alcohol to clean the contact.

I tried a 2G and a 3G SIM on mine, and had the same result, so my problem is different.
My device just doesn't register with the network, no matter what provider or SIM generation I choose.
Can I ask for a RMA if I unlocked the bootloader?

I do not know you definitely do not pass it under warranty

Ryan then you say you clean the contacts of the nexus or the sim with isopropyl

Mine is now doing that as well and so far everything that I tried isn't fixing it. I get it to connect briefly with edge and then nothing. I am going to try a new sim tonight after work and see if that helps, otherwise unsure of what to do after that...anybody got any answers or suggestions?

I've been suffering from this... have an RMA coming but I got mine to work. Make sure you also have CDMA preferred on there or whatever the default is. If it says unknown you have to reboot the radio somehow. I pulled my battery, waited 5-10 seconds. Then i went and checked airplane mode on and off. Then i checked the service menu again. I can't remember if i had to pull the battery another time but it came back from "unknown" to cdma preferred. You can also try turning the radio on and off via the service menu. Finally select your radio bands for your region by pressing the menu button under phone information again in the service menu and select radio bands. I'm not sure if automatic is a good or bad idea but it couldn't hurt testing it if you still have some issues even after selecting your region specific bands. After this you should be able to maybe search and register or you may need to turn the radio on and off again via airplane or the service menu. I played around with it alot to get it running again.
Also I'm tmobile usa using the one for t-mobile bands. I'm not sure if CDMA preferred is a world wide setting or if its gsm or something else.. but the bands are specific to your region definitely.

Problem Registering with Network after flashing GPE ROM

Hi There,
I have been scratching my head for weeks now with no luck after searching hundreds of times for a solution and I hope I can find it here today. I purchased an Sprint HTC One M8 from Best Buy together with an unlock code. I received the phone in Africa and I was excited to try it out. However, when I put in my local carrier Sim Card I could not receive an unlock code request. I tried many fixes but I did not get anywhere.
After days of trying one fix after another, I decided to unlock the bootloader successfully, install a custom recovery (TWRP), I was also able to achieve S-OFF using sunshine's tool and write CID to 1111111. After that I tried different kinds of unlock methods like using config.dat and using the Sim Unlock Helper tool. But no luck.
I went ahead and flashed my device with the Sprint M8 GPE 5.0.1 ROM. I was successful and I noticed under settings - cellular networks I am able to see all network operators in my region. However, when I try registering with my carrier I get a "Sim Card can not connect to this network" message. I do not know why.
When I dial *#*#4636#*#* and access phone information, I selected GSM only in preferred network type. Under select network band there are only 4 options: Automatic, USA Band, Band mode 6 and Band mode 7. I selected Automatic.
I have literally tried everything I can think of as I am kind of new to this. I really hope someone can point me into the right direction in unlocking my device once and for all. I love the phone and I do not wish to sell it off. Please let me know if there is any more information that I can share. Thanks for your time!!

Hello,
Are you still having this problem?? Cause if you do I am really curious if you found a fix for it? I am experiencing the same problems. A friend of mine gave me this One M8 which has no owner anymore so i decided to fix it. I replaced the screen due to water damage and did bootloader and root succesful. I can also see my network providers but as soon as I try to register it also says "Sim card cannot connect to this network". Who has the ultimate fixxx???
Greetings,
Rob

GS6 Active Network Issues Unlocked

Hello! I Had my Blue Camo GS6 Active 64 Stolen last sunday, Bought A White GS6 Active 64GB Model to hold me over and its in real good condition. But its Network Unlocked and noticed the setting on my 32GB Black And my old Blue 64 phone were set to GSM/UMTS. This for some reason is stuck on WCDMA? I Don't even see a GSM/UMTS Option and was wondering what i should do here?
I Did a few system updates thinking it may automatically work but whoever had the phone before must of changed something, even a Factory Reset didn't solve the issue. So i get the phone in the mail, power it on and everythings good no SIM yet but it had 4 bars, Pop in the AT&T SIM and restart and bam No Signal at all. I Changed it to GSM And get nothing. I Notice if i set to LTE/UMTS When i'm up the road it actually pops up 4G LTE And works too! But i get home and Poof No Bar. Its probably cause it usually does get knocked down when i walk inside to 4G But never no bar.
Anyway i can Flash a Stock OEM Modem? Or a way to force the Network settings to Reset to OEM? Had this... well that GS6 Active for 3 years never had an issue but mine was AT&T Network Locked i never unlocked it. This is Network Unlocked and notice a lot of what seems to be Foreign Networks? Network settings I've never seen before that's for sure.
Help will be appreciated!
Really need this to just work by Monday and AT&T Support sucks lol! Best buy couldn't help me, 3 AT&T Stores couldn't help me cause they don't sell it anymore and i didn't buy from them. But i know its fixable i mean i get signal if i flip around to the WCDMA Setting when i'm home, And before i walk outside i hit LTE/UMTS and i do get a 4G LTE Signal when i get up the street. but i'd rather it Automate like it did before so i don't have to keep doing this.

Yeah this sucks, Like Mint White 64GB S6 Active. Just this i didn't expect. I've Switched sim cards back and forth, took the sim out and tried to change the band but that doesn't work. I've gotten to the Network System menu and put everything on Auto. I Have it set to LTE/UMTS and i get nothing, i take the SIM Out and restart, 4 bars are there. put the SIM In and Boom no signal. I've tried to change the GSM/UMTS Band to Automatic but it just says Unsuccessful. But i have that feeling if i can get it to say Successful it will work.
Anyway to use my laptop to connect via ADB And Force the band to change to auto? Or anyway to get it to stick to Stock settings? I Still suspect whoever had this before did something to the Radio and Network settings and i can't figure it out for the life of me. AT&T sure won't help me lol! And Samsung just wants me to bring it to a repair shop. While i was actually at a few repair shops around here and they know nothing about these.
It's the only phone i'm comfortable with. The S8 Active is ok but without physical buttons it doesn't really serve me like this did... and i don't really care for Bixby button can't be customized. Also noticed Otterbox doesn't make Defender series cases for it so i'd have a bit of trouble getting a beefy case on it.

Ahhh.... i get some signal in WCDMA Preferred. Fixed a SMSC Issue so text's go out and i receive them if i move around a lot.
Signals still bad not like it used to be. Why do i get a Signal On WCDMA But not GSM Auto Or LTE/UMTS? Is there anyone that can help me get to any advanced network option's or a way to change the Band to Automatic? I Try to select Automatic Band which is the default i believe and it just says Unsuccessful.

Have you tried just refalshing stock rom???
I know you already have done this but sometimes it doesn't work first time(few have mentioned issues that took several flashes to solve it)
The reason folks are not replying is quite possible know one has any idea why this has happened.
I had an s6 Active that everything worked other then 4G and nothing worked.. It was a factory refurbed and Unlocked. And no matter what I did it simply would not worked... I returned it and go a replacement... It suggested it had been damaged internaly in someway..
Can you return yours for a replacement/refund???
Sorry am not actually able to help.
regards
Lohtse

I might return it. I figured out why messages were not sending i messed up the smsc settings lol!
Very unique issue here i see 4G pop up and i get calls and data flows. Sometimes 4G LTE magically appears and everything stops working till 4G shows up.
Pretty hard to find this GS6 Active in 64GB anymore.
If i take my sim card out and dial *#*#2636*#*# i think? Or it might be *#*#0011*#*# it brings up network options. I notice if my sim cards in that menu shows up empty. Something maybe wrongly set in there but not sure how to tell. Never found a way to successfully set the GMS/UMTS Band. And with no way to really root it or change anything through the pc is probably going to make this even more difficult. Phones in great condition though i dont think theres damage i believe its a network setting somewhere i missed... or at&t sucks lols! Every sense i got robbed on the 18th its been nothing but a big problem getting a phone working again.

Reflashing stock rom? Like Android 5? Its in Android 7.0.1 now. Id be interested in doing this but going back that far is spooky i dont wanna destroy it. Ive seen people say its possible and others say its not possible to go back.
That would probably work though! When i got my S6 Active Camo Blue 64gb New it was Android 5.0.1 and i think more network options were available. Then in 7.0.1 they all disappeared.
Never had issues on that phone i can't believe it was robbed from me. Not like i dropped it or lost it either it was robbed from me! Police did nothing even with the fact they threatened to kill me and everything. Police did nothing... and after 14 hour shift im not exactly ready to fight with 5 people.
