[Q] Reception problem for Samsung Galaxy S - Galaxy S I9000 Q&A, Help & Troubleshooting

Going to send a donation to the site if this works as it'll save me money I would spend in a shop getting it fixed. I read the rules and did a search for a similar topic, but each one seemed to be slightly different from my situation, I hope this is the right area of the forum as I'm new to it.
The phone was brought from T-Mobile but I also have an O2 account that I use for work so would like to be able to switch between sims with ease. I'm a total newbie with Samsung, especially the way it works so treat my question as if you were answering a child
I'm on a mac and used the method posted on this site to unlock it and that worked (as far as I know), it said unlock successful etc but now the sim isn't recognized apart from it being on O2, and there is a symbol of a sim card with red around it and a blue circle with a line through it at the top where reception would be. What's even more worrying is that the original T-Mobile sim card is getting the same response as well.
Thanks a lot.

Try to hold it correctly as said Steve

Are you sure you fitted the sim card properly? Last month I had a blonde moment when I inserted the sim card the wrong way and wondered why I had no reception.
Also you might want to clean the contacts.

You could also check you have network settings for O2 .
Suggest it may have failed to unlock if its not the settings .
Just borrow another network sim and try that same error on sim = not unlocked .

I've tried that, but no luck. It says my sim isn't able to connect to that provider, despite it being an O2 sim that works perfectly on another phone. Or do you mean network settings that needs to be manually put into the phone?

Hah, I actually read about a few people doing this as I was searching the net for a solution but I have put it in right. I even put it in upside down just to be sure I wasn't being an idiot.

?

Have you checked your APN settings in your phone?
To get to the settings section, follow this path.
Settings>Wireless and Network>Mobile Networks>Access Point Names
I was going to post a link to a site that has all the U.K carrier settings, but I need a few more posts to be able to do that.
Just do a google search for each mobile carriers APN settings and manually enter the information.
I'm not sure if this will solve your problem, but it's a good place to start.

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)

No Service- HELP!!!

I bought new TyTN II, and when I insert my sim card, he doesn't recognize it, in the top of the screen is text NO SERVICE. In the start/settings/connesctions/connection setup, there is no my country to select, or my operater. Does the new cooked ROM may solve my problem? Please help...

Does it say no sim card, or just no service. If it doesn't recognize the sim card. then it is probably sim locked. If it recognizes the sim card, but just offers no service, it could just be your connection settings.

Hello,
I didn't want to start a new thread, because this one is somehow connected with my problem
So here it is:
I've been using my phone for about a month, it used to show full network ect. My friend gave me an anthenna for gsm mobiles (well, sometimes it didnt work properly when I was in the basement i.e.) so i tried it. Worked perfectly, except it was sticking out. So i thought that I don't want to use it and disconected it. Since then it shows no service, sometimes "1 dot" in network display. Tried hard reset - didn't work. When i put the anthenna back, it shows full network again.
Please, tell me, what should I try.
Thank you in advance
I seem to recall reading somewhere here that once you put in an external antenna, something gets tripped and the phone will only work with an external antenna from that point on.
Sorry -- don't recall any details. Try searching.

gophone sim does not prompt sim unlock code

I have a weird issue, and was hoping that maybe someone could shed some light on what I am seeing.
I just got a used G1 on ebay, which I want to unlock. When I put an ATT GoPhone sim in and boot the phone, I am not prompted for a sim unlock code. It is not unlocked, I know the this as I do not connect to the ATT network at all and cannot modify any of the APN settings on the phone. I know that I need the prompt for sim unlock to actually unlock the phone. Fortunately, I just found an old international sim laying around and that one seems to trip the prompt for the sim unlock. My questions - why does the GoPhone sim not cause the phone to prompt me for an unlock code?
Thanks for your time.
Hmmm that is a good one. I used a normal att sim and it asked for the code, is it a older sim? Maybe one from the cingular days? To weird man.
the gophone sim is a new sim, just purchased and activated. I know the sim is okay, because I can use fine in another phone.
I have an unlock code on order. Hopefully, using my other sim to trigger the code request, I will be able to do the unlock. Hopefully, then, the gophone sim will work fine. I hope to post positive results back later.
thanks
Yea you can unlock it with any sim and switch to another and it will work. I know a few people on here use att gophone sims so you should be fine.
so I was able to sim-unlock the phone using a different sim.
I still have a real problem though - when I put the gophone sim in, I still find myself unable to connect. I even go to settings>wireless controls>Mobile Networks>Network operators and try to manually select at&t. When I do, it says "registering on at&t" for a while and then says "Your SIM card does not allow a connection to this network". Again, I know this sim works - I have been using it in another phone.
What do you think I am doing wrong?
Thanks
It sounds like something is ****ed up with the sim, even though it works for the other phone. Do you have any friends with att sims? Something really sounds off here and if it isn't sim related then I don't know what it could be.
will try to find someone with an AT&T sim, but I don't know what the deal is. I even tried an international sim (that should roam on t-mobile here), but I could not get that to connect. I have tried putting in a tmboile sim and that seems to be the only thing I can to talk to a network
As a side note, no APNs show under settings>wireless controls>Mobile Networks>Network>Access point names when I put non-tmobile sims in. When I add one, it still does not show up on the list.

HELP: Shows Signal but cannot use for calling,data,messaging!!!

On my Phone(Andromeda 2.0 Themed), I get the indication of having 3g or any signal at all and the minute I attempt to send a message, make a call, or surf the web it is unable to send that message, unable to make that call, and unable to surf the web. Help on how to fix this?
NOTE: A flash back to stock DID NOT help this problem at all.
EDIT: Changing APN isn't really working(Cant leave the APN type as not set because it auto sets it to internet+mms when I save) and I am starting to get a little frustrated. The reception was really working fine earlier today but now its just weird all over. Please help me out you guys, I really need this working.
EDIT2: Please help guys, I really need my service up for tomorrow.
EDIT3: I am going to AT&T today to swap out my SIM card!!!! I am all Odin'ed out and I will check back if this works.
First try to enable airplane mode. Then turn it off.
If that does not work check your apn settings, under wireless and network, mobile networks, access points

Doing that now.... The signal bar indicates no connected network.... Trying the second thing you suggested....
For the second option I am under Wireless and Network/Mobile Networks/Access Points.
My options from there are AT&T 310 410(the text under it says wap.cingular)
What do i do from there?????
That reads correct. Unless you are on rogers. Hmmm. I am on the same rom but do not have the same issue. You may want to manually configure you're apn. You may want to search the captivate forum for at&t apn settings. I think you can find them in one of the stickies
I am on att dude. Thanks for the advice. You are positive its the APN though? This happened to me on Phoenix Reloaded too.

No I am not sure, I have not had your problem but this is where I would start if it did. The apn settings are posted in the captivate development stickies, captivate directory
Okay, so I configured the APN settings to what was found in the thread. Problem is the only thing I cannot configure is the APN type. Hm. Any help?
I am sorry I hope someone who has done this reads this and has a suggestion but I have not had to do this
Read through the sticky, maybe yet has been discussed
Read through it and nothing. It wont let me keep the APN type as not set and it automatically sets it to internet+mms. Any ideas?
Have you posted in the andromeda thread? Maybe the devs may have some ideas
I just did, hopefully they have an answer and if they dont hopefully someone will post an answer here....
I had the same issue back a few weeks ago. I called att, got a replacement phone, and it did it again. Turned out to be a bad SIM.

Well, this sim card JUST started doing this. So are you sure it is just the sim? I mean, if I go to the store to get a new sim, will they ask to see my phone? Will I have to flash back to stock before I get a new SIm?

Do you think the person in the store will have any idea what a custom rom is? Chances are they will change it no questions asked

Well, thanks, I will head first thing in the morning.
I got the same problem at certain locations, such as my university. Haven't been able to get much help... Gonna try getting the SIM changed as it's a pretty old SIM. Weird thing is that it works fine on my Sony Ericsson G705/W715.
So almost two months of owning my Captivate that I got from Rogers (BNIB from Kijiji) and I noticed that at a certain area in my school, I have 3/5 bars of signal yet I can't seem to text/call and use the network. Is this a network problem or phone problem? Or can it also be my SIM? My SIM card is pretty old. However everything was fine when I use my Sony Ericsson W715 in the same area.
I should add that my friends on the same network beside me, they can text/call fine, which leads me to believe that this is a phone problem. A poster over at Howard Forums suggested network congestion, but it seems impossible because everyone else can use their phone fine.
I've tried different modems too, but it doesn't help. It's like my Captivate doesn't want to work at certain areas of my school.

I am just going to change my SIM. It is about 4 years old now and I think that means it needs to be replaced. I actually worked fine at my home before and now it cant even find a network. I am going to head out for a new SIM in a little bit, I will get back to you on if it works then.
