unlocked G1 no signal with new sim - G1 Q&A, Help & Troubleshooting

Hi, hoping for a little help. Have just unlocked my T-MOBILE G1, but when I put my vodafone sim from my nexus one in it, it does not work, vodafone said it should work ok. Any ideas gratefully received. Many thanks.

it takes a few moments to take signal, also go to settings and turn off 3g it might help also reboot phone while new sim is in

Tried those, but still no joy.

o2 sim not seen?

Hi all,
I bought an Alpine, brand new (unwanted contract upgrade) from eBay, received it today and put in the PayG o2 sim that I bought from carphone warehouse. The phone is locked to o2, as I tried my old virgin sim and got the old "Enter unlock code", but with the PayG sim, it goes straight in, except there is an exclamation mark next to the signal indicator. I can't figure out what it is. Do I have to wait, say 24 hours for the sim to receive a signal? Or is it something more suspect? I can't make calls or do anything that requires payment from the sim.
Cheers,
Karl
EDIT: I have googled, and done a hard reset. I have come across that problem of not being able to select "Prepaid" for the simcard. I'm even using an o2 sim card! Is there something else I need to do? I've seen the settings for gprs and mms, but I just need to get it so I can use it as a phone! Please help!
Can nobody help me?!?!?
Have you tried calling O2? I had no signal for a few hours last night and had the ! mark next to the aeriel symbol, maybe there were network problems in your area as well?
Alternatively have you tried the SIM in another phone to check it's been activated correctly?
You could also try SIM-Unlocking your phone using the tool somewhere on this forum (Search should find it) and try it with your Virgin SIM to see if it's actually the phone which isn't working.
Apart from that can't help.
Sorry!!!!

I have emailed them about the problem, and may well back it up with a call; I just don't want to be on hold for an hour listening to someone playing the trumpet with their arse.
My sister has an o2 phone, but is out at the moment. I will check with her when I next see her.
I have been looking at the all in one unlock tool in the General section, but am wary of it as I don't want to brick this phone. Will it wipe the WM2k3 OS do you know? Or is it just like an application that searches the system?
Thanks!
UPDATE: Have just decided to bite the bullet and try the all in one unlock. It worked and my XDA is now on my old Virgin Sim. I will try my o2 Sim in my sister's phone at some point. Could it be that I have bought a dodgy o2 sim?
UPDATE: I tested the Sim in my Sister's phone, and it came up with "Unregistered Sim". I then put in an unused Sim that she got as part of a promotional freebie type thing and it registered in under a minute! I'm going to take back the Sim that will not register, but before I do, is there anything else I can try?
SOLVED
Simcard refunded, am using spare that my sister had as it worked straight away.
SOLVED
Glad to hear that - I had just dug out this morning the SIM unlock program and was going to PM it to you then I saw your post.
Enjoy your phone!

Thanks for your help buddy! Much appreciated

Help revive my dead Kaiser

I have a big problem which I hope all you Kaiser gurus can offer some advice:
I got my Kaiser two weeks ago, pop in my USA T-mobile sim card (GSM only) and it worked perfectly. I then went over to Taiwan and the device was put in Airplane mode for about 10 days. When I get back to the states, the phone no longer works; all other features of WM6 works except it the phone service.
It cannot find the t-mobile network regardless in auto or manual network selection mode. I tried the SIM card on my other phone and it works perfectly so that rules out the SIM card. I did a hard reset and it didn't cure the problem.
Question is, can the altitude or air cabin pressure somehow killed the phone portion of the unit?
What other diagnostic methods do you recommend?
Hmm I dont know if this is a good idea but emergency services like 911 should still work, even without service. And by that I mean without being signed up for service. So it might help to test 911, then hang up if it rings once. Just to see if your radio still works. If it does, then the issue might be that the phone is not configured correctly to T-mobile.
Now this is only true in the USA. I'm not sure where you are from. But given that the USA has just about the oldest infrastructure in any developed nation, I'm confident it can only be better where you are from.
No, 911 does not work. Does this mean my radio is fried? What can I do?
hmm... this sounds like a bad radio flash gone wrong... and not saying so!
I tried it with my friend's AT&T Sim and it worked perfectly. Does it mean it's the carrier's problem?
it means probably your phone got sim lock somehow. Just do hard spl and unlock it.
I'd get another T-Mobile sim card if your device works fine with an AT&T sim. I realize you said your T-Mobile sim works great in another phone, but that's the only thing that makes sense.
Ok I'll try that. Problem is, I have several other T-mobile lines and I tried those SIMS already and no cigar.
Anyone else can contribute any ideas? HTC is not support me because this is an import phone.

This is MISLEADING info !
Hard-SPL = CID unlock = ROM options
it does NOT unlock the SIM !!
hello all
i got the "no sevice" problem which looks like the same as Valleydog's.
i got my kaiser about 1 month, everything goes very well
today im in class and turn on the flight mode.
when i turn off the flight mode, it cant find the sevice any more,it tells "no sevice"
i cant dial any number including 911,86,110 etc......i swap my friends' cards they couldnt work,too
oh,just a nightmare to me, i flash the htc ship rom(which contains a radio),problem still...
could anybody help me, was it suddenly sim locked? possible?
Why such bad thing happens on me(good person)...........
KAIS130 with hspl v1,flashed many roms without problem,just this problem suddenly scares me
Sheng
This happened to me briefly the other day; running a stock T-Mobiles Vario III with NO rom flashing done to it.
I went to make a call and there was no service. The phone had been in my pocket for a while. I soft reset it and it worked after that, but took about 5 minutes before it picked up a signal... It's been fine since though.
This really sucks... I will head down to the T-mobile store and try out all their SIM cards until I find one that works.
The thing that puzzles me is that the other carrier's SIM (AT&T) works fine

Haha....im sure its got nothin to do with that....mebbe u dun pray enough
Here's an update...I tried 3 working SIMS cards in T-mobile store on my phone and it still does not get signal.
Very frustrated at this point.
My phone worked intermittently at one point but now it's dead again. What a piece of crap.
This is so annoying, and HTC have no answer regarding this issue.
It is clearly not a hardware fault!!!
I have the same problem & it is so frustrating you guys can't imagine.
I have always loved HTC machines, but I am thinking never again!

saper747 (andre),
Where are you located and what have you done to troubleshoot the problem so far?
Did you call T-Mobile to see if they have something configured wrong on their end? If the phone works with an AT&T sim, it would seem something on T-Mobile's side wasn't right.
There is nothing wrong as confirmed by T-mobile, the same SIM works on any other unlocked phone except my Kaiser

Problem after unlock procedure

hi peeps, i have put my o2 xda2 back into service and used the excellent unlock giude from this forum (itsme' guide) and unlocked my phone to try and use with a t-mobile sim.
Having run the v.1.6 on it, when i put my t-mobile sim card in the phone i get the t-mobile logo and 4 bars of reception however it wont allow to me to make/receive calls or sms etc any ideas on how to fix this or what the problem maybe?
thanks in advance
it sounds like tmobile sim is old.try sim in different phone and see if it has same problem.if so a new sim should cure it

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

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.
