Your SIM card does not allow a connection to this network

I'm curious to know if anyone with a non t-mobile g1 experienced the same.
My phone was working fine this morning until it stop being able to register on the network with the above error. The only thing I did with it this morning was to put on a screen protector. I doubt it's related
A reboot in recovery mode and a wipe fixed the network registration issue so I guess some data were corrupted.

Hi.
I have the same problem now. Have tried to hardreset but still No service..
Can you help me??

Just get a new sim card

I have the same problem now - but it is extremely frustrating and I have tried, since I first wrote what is below to downgrade - but cupcake will not let me.
I have an unlocked - but also unrooted G1. I use it in Europe and in the US. While in Europe I got the message to upgrade and without thinking I did. Then while in Europe I could no longer use the phone as a phone. The update went fine and I had ‘cupcake’ but any SIM I put in (T-mobile, BASE etc) there was no signal and when I went to do it manually I got the message “your SIM does not allow a connection to this network”
So I did a hard reset, but then I could not get pas the start screen since I had no data connection (but I did seem to have phone connection again.
In a layover in Atlanta I tried again - I was able to log in and set up and all was great and good. I should note that I have an old data plan and use an alternative APN to access data. This worked fine in Atlanata where there is 3g connection.
Back home no win Florida… no phone service - same as in Brussels. same message. Worth noting - there is no T-mobile 3G service where I live.
After thinking about this for a while I am wondering if somehow I did not get the correct or full radio update…
if this is true - do you have any idea how to remedy the situation or how I would know if this is the problem?
I appreciate any help.

I have the same problem, any news about this?

I had this issue randomly about a week ago. Reboots didn't work, and I really didn't want to go through a wipe/re-flash. I called T-Mobile, they had me reboot [after I told them I had already done it] --- they ended up deleting me from the network and reboot my phone again, which apparently re-registered me on their network.
This is on T-Mobile US (SW Ohio to be specific)

Does anyone has any news about that? I was told that this might be a radio issue, so I tried to downgrade my celphone to version 62.33.20.0H_1.22.12.29, (using fw 1.0 too), it worked for some time then suddenly it gave me the same error that my sim card it's does not allow to this network, so I forced, again, to my network and the same message appear, I tried this sim in another celphone and worked, I tried another sim on my G1 and it didn't worked, this celphone was working when I lived in the US, but here in Brazil it's not working just like there.. my guess is that the Radio in other countries has any bug, does anyone here was able to fix that? any further advice?
thanks.

weird, i have this issue tonight on one of my unlocked g1's that would normally be working on ATT.
I'll update this post if/when I find a cure.

I've been having the same issue of and on for a couple of months now with a G1 on Dutch T-mobile with dutch T-mobile SIM card, which is odd. Running CM mods so maybe the fact that i'm runnig non stock fw causes this?

I get this problem from time to time. Almost never around town where coverage is good, but when I'm on the road in a lot of places where coverage from any provider is poor this happens, especially if it keeps having to switch back and forth between roaming and not roaming. I even get this on T-Mobile and they are my provider. Usually a reboot fixes it, but not always. I've never had it last more than an hour though.

Try reflashing the radio on your phone. Sometimes this helps solve odd connection issues.

according to my tries, this isn't related at all. i'd like to check in on this thread and see a known fix instead of maybes.

Had the same problem
I had this problem about a month ago, apparently simcards can go bad after a while; I had the same simcard for 5 years and it became unreadable. I went to a t-mobile dealer, bought a new simcard for $20, and I was finally able to get my connection back. It's a bit of an expensive route, but at least I didn't have to replace the entire phone.

my att sim is 4+ years old, but works fine in all but one phone in question, with the above error. also, I have a brand new tmo sim that throws the same error, only on that one phone- which leads me to believe its not a sim CARD problem at all.
all my phones are unlocked, in case of weird problems with any gsm carrier.

Looking at your sig, is this one of the phones with gnav? Because some of the earlier techniques of installing gnav have resulted in a "no service" signal. If it is one of the phones with gnav, try pushing the old build.prop files back into the phone.

gave it a shot, used the normal build.trout... and same results. surely someone at tmobile is familiar with this problem ?

Same issue.
I am running cyanogenMod-4.2.12.2 with radio v. 2.22.19.26I on a t-mobile mytouch. I will lose service and the phone will not automatically reconnect to the network. When I manually select my network (wind mobile) it sometimes connects fine and sometimes I get a "your sim card does not allow a
connection to this network" error and must reset. I found this thread code.google.com/p/android/issues/detail?id=2845 where dozens of people running all different hardware (G1-hero) and all different software (stock cupcake, cyanogen, etc) all experiencing same problem. It seems this problem is happening regardless of the network (T-mobile, vodafone, orange & wind mobile). The problem seems to be happening through all different variables. Changing sims does not seem to fix it. Anyone have any ideas, this is very frustrating.

I've seen this issue as well, with the new Canadian provider Wind Mobile.
The issue seems to coincide with new towers being added onto the network. There are minor service disruptions that result in the network being temporarily screwed up. Going into and out of airplane mode seems to fix it every time.
Also note: These minor service disruptions do NOT ONLY affect my phone, but others (different brands) as well.
They've gotten better at adding towers without blowing up the whole network. It started out happening a few times every day. In the last week it happened only once.
Funny observation: When this happens, the DATA SERVICE recovers automatically, even though the signal gauge remains in X-no service mode. This part is probably android and/or dream related.

It is related with network
I've started to have the same issue tonight. I've rebooted several times and changed the SIM card with another from another operator but nothing helped.
Then i remembered that since I bring this phone from Belgium to Turkey, the regulations in Turkey requires the phone to be registered with its IMEI number to the telecomunications supreme board.
Altough i had initiated the registration process months ago, i thought that there may have been a problem with the registration, so i checked the boards web page.
It turned out that my IMEI is not registered and this most probably is the reason for the not allowed connection.
Tomorrow i will try to reach the board officials and i hope it solves the issue.

do you know what happened? i having the same issue right now and cant seem to find a way to solve it..

Roaming At All Times

I recently unlocked my G1 to work with the ICE Network here in Costa Rica.
I was actually stuck for like 3 hours thinking about flashing and trying differen methods for the activation because for some reason it wouldn't catch the 2G Data Services (After I Followed alot of APN Settings etc)
When I was about to give up , I saw what seemed like a new icon (which ended up being that it was receiving data)
But I also noticed the R in the signal strenght icon, which I managed to figure out was Roaming.
This has not gone off since I got the phone, I got Donut 1.6 , I got the phone yesterday, It works perfectly, It receives calls, Dials, Msgs fine, everything like my old S.E phone, the internet is even a tad faster, but I'm kinda worried about the Roaming sign being there.
I'm not really worried for any International SMS like it was reported, because the crappy service here doesn't even have that, so It won't happen, and I don't even think Roaming exists here.
Any help to that?

You might want to post your APN settings so others can see if you need to change something.

Out of noobing around, I tried to play with the APN settings, but I went back to the old ones, now my Internet doesn't work..

http://modmyi.com/wiki/index.php/Carrier_APN_Settings#ICE_.28Costa_Rica.29
Thats the only thing I saw. Saw a couple other places that had the same info. If that don't work then maybe someone else can help you thru.

This isn't an APN problem, it is a SIM problem.
Your provider has one set of numbers on your card, and another set of numbers that actually identify the network, and they don't match. Technically, from the phone's point of view, you *are* roaming, even if it is the same provider. From the provider's point of view, you *aren't* roaming.
Up until cupcake, we had that same problem here in Canada when using the "Fido" network (which is owned and operated by "Rogers"). The network identified itself as "Rogers", the SIM cards identify themselves as "Fido", the phone think's its roaming.
So; you don't need to worry about roaming charges when you are actually connected to the correct network.
BUT; You don't have an easy to read display to tell you when you are *really* roaming, nor can you make configurations that are based on whether you are or are not roaming.
Edit: You might be inclined to report it as a bug against AOSP. Even though it technically isn't a bug, the workaround for it needs to be input and that needs to originate as a bug report. http://source.android.com/report-bugs

Thank You very much.
I actually wasn't really worrying a whole lot, because Roaming doesn't exist here in Costa Rica. ( We are expected to barely get 3G this year, and there is a wait list for that for about 200,000 people ).. If your signal goes out, thats it, you got no signal .
thanks for the quick reply, another thing I wanted to ask. I've had the phone since like Sunday, and When I got it it was Version 1.01, So I got 1.5 Cup Cake, and eventually 1.6 Donut without even trying the phone at any point, I'm getting alot of force close msgs, for something regarding android action or something like that, I don't recall the exact msg, but I keep getting it , when going to the home from a application (any) or doing something rly fast, it blacks out, resets the desktop and shows up again, I read somewhere you had to do a factory reset (which bugs me because for some reason mY internet wasn't working until like 5 hours after I unlocked the phone).. Thanks

Yeah, a factory reset might help. Especially when you've done that many updates over a short period of time.
Write down your APN settings on a piece of paper and do the factory reset. It will STILL have 1.6, it will just clear the user data, which after just one day, won't be much anyways. Better to get it cleaned up now rather than wait until you have a big pile of configurations you don't want to lose.

Thanks, Did that, now my G1 Is much faster and won't crash.. Awesome

[Q] Internet stopped working on Atrix...

Hey guys. I'm new here, browsed around the forum a bit and I definitely like the stuff goin on here!
I'm having a big problem with my Atrix.
Bought it on Bell, unlocked it to use on Rogers and it worked fantastically for the first week, then randomly the data stopped working on Monday.
My APN was working fine before, Rogers even gave me an alternate APN to try and that doesn't work either.
I've done all the basics like switching it on and off, taking the battery and the sim out. Rogers even said they reset my data connection for me but no luck.
Do any of you guys have any suggestions?
My settings are:
Name:rogers
APN:rogers-core-appl1.apn

I guess you tried switching data on and off again, removing the APN and creating it new?
Not sure if you can just flash the 1.2.6 SBF for the US version (and then upgrade, root, whatever)? The hardware should be identical, but not sure if anybody has tried.

Thanks for the tip but yeah I've tried that too.
I've tried everything short of a factory reset for the phone. Any idea if that would do anything?
I haven't rooted yet, I wanna get this working again first since it was working perfectly before. I'm within my 30 days but I don't even think I can exchange my Atrix for another since I unlocked it

Rogers were blaming the handset and Motorola were blaming the network.
I was within my 30 days so I just exchanged it for another.
Hopefully I'll have better luck with this one.

HELP! Unable to connect to any mobile network - DHD

Hi Guys,
Wondering if anyone could help? I think I may have turned my DHD into an expensive mp3 player! I don’t seem able to connect to any mobile network Apart from that the DHD functions perfectly (working wifi/gps) - it has been working fine in the past
I can’t make/receive any calls / text message. When I try to connect to a mobile network I receive the following error:
- If I choose the network manually myself (o2 for me) I get "Your sim card does not allow a connection to this network"
- If I try going for the automatic option I get "Unable to connect to this network at this time. Please try again later."
- I'm also getting the notification every 10 minutes to "Set current time" - I don't know if this is related but I assume so since both issues started at the same time!
The problem occurred when I decide to give RCMix a go through ROM Manager. It appeared to flash fine and was running smooth and quick until I noticed a few hours later I had no mobile connection I'd done this a few times before with RC 7 and CoreDroid and hadn’t experienced an issue before.
First thing I tried was to recover to my previous setup before the flash (using ROM Manager) - the phone restored however the mobile network still remained unresponsive! ...this was the same for all my previous backups. I tried clearing cache and dalvik-cache. I even tried reformatting the phone at one point.
I know it's a fault with the phone and not the sim, I'm just not sure what. I've tried my sim card in another DHD and it worked fine. I have also tried different o2 sim, an orange, vodaphone and T-mobile sim card in my phone – all of which give the same problem.
I’ve tried resorting the phone with a few different RUU’s, and even a German one just because it was o2 branded and I’m on contract with them:
- RUU_Ace_HTC_WWE_1.32.405.6_Radio_12.28b.60.140e_26.03.02.26_M_release_155891_signed
- RUU_Ace_HTC_WWE_1.72.405.3_R_Radio_12.28e.60.140f_26.04.02.17_M2_release_161342_signed

- RUU_Ace_O2_DE_1.32.207.1_Radio_12.28a.60.140e_26.03.02.08_M_release_153755_signed
I then re-rooted the phone with the use of Visionary+.
I’ve tried turning the radio off then back on, both by switching airplane mode and by using the hidden option *#*#4636#*#* and I’ve also tried re-flashing the radio and even a different more up-to-date radio:
- Radio_12.28b.60.140e_26.03.02.26_M (original)
- Radio_12.39.60.19_26.06.04.06_M
I’ve checked out the APN and it appears to be correct for o2.
I’ve done simpler things like restarting / powering off, removing the battery, re-seating the sim, re-seating the sdcard and booting without the sdcard!
All in all I’m running low on idea’s Could anyone please help or throw some idea’s at me, it would be very much appreciated!
Thank you.

Did you try on your phone pad to type *#06# in order to check your IMEI?Do it and check on your phone's box that they are the same
Sent from my Desire HD using Tapatalk

Double check your SIM card slot to see if its clear of any debris. Other than that, there is a definite fault. Was your handset originally branded?

Sounds like a blacklisted imei.

HTC HD2 with error connecting to the network problem
I have the same problem! I bought a phone from ebay "new" and I have not been able to connect to my network AT&T. The phone has android gingerbread 2.3.2 Nand, and I have tried everything in the book to see if I can connect to the network but to no avail. I have been going on forums for the last three days, and if anything, I just want to know what is wrong with the phone. My sim works on other phones fine. There is enough signal in the area (ive always had signal where I live), and tried resetting, taking the battery off, flashing different roms, even went back to Winmo and nothing has worked yet. My IMEI on the phone was different from the one the box, but was the same on the phone as on the inside IMEI.
WHat the heck is going on? Please ideas or help!

Thanks for the quick replies...

Tried clearing the slot, there is no visible signs of blockage... also I bought the handset second hand - I've never seen any branding however when I bought it the previous owner did tell me it was previously locked to vodaphone and he had rooted it so that he could use other sims cards. Which is why I orginally tried a vodaphone sim card too.
Thanks for your suggestions so far guys

Just a quick update, I've been grasping at straws and I've also tried a few more bits below, none of which have worked... I think I may have to leave this one to rest. Just wanted to let others know who may be experiencing the same issues

Replacing the mtd0.img as mentioned here: http://forum.xda-developers.com/showthread.php?t=691639

It sounds like a fault. If it was network barred you would still receive a signal, for emergency calls. Can you return the handset to HTC for a warranty repair?

I still get a message on the lock screen saying Emergency Calls only - although admittedly I haven't tried calling the emergency services to check if it gets through.
Not being the original in-store purchaser I don't even know the age of the phone but I'm guessing probably over the 12 month warranty period, sod's law - I'll give them a ring and see what they say

My DHD was from the first batch and is still covered by warranty. How did you check to see if the IMEI was blocked?

I had a similar problem to this one. My mobile data connection gave out after my DHD's temp reached about 38 degrees while playing with it in the sun. A little while later I lost coverage completely, same as you. I tried everything, flashing ruus and re-rooting, re-s-offing, everything. Ten different ROMs, radios, kernels etc.
Eventually I gave up, figuring I had confirmed it was a hardware issue, and popped my sim in my old nokia so I had a usable phone and to get on with my life after wasting so many hours. I left the DHD with the battery removed, and ended up not coming home for a couple of days.
When I got home and decided to start playing around with the DHD again to see if I could get it working properly, I noticed the issues were gone.. I've tried to reproduce this problem out of curiosity, leaving the led light on high for a while, making the phone hot. Nothing. Since then I've flashed everything imaginable, and I've switched back and forth between two radios all week. No problems.
Strange, I'm guessing I have some form of hardware damage, but everything is running smoothly now at 1,5 GHz - no unstability of any kind.

I have done that actually! I took the battery off, and put the phone back in the box just to get on with my life. I left it sitting for a day and a half I guess, and I came back BUT unfortunately, unlike you, the problem is still there. The phone tries to look for signal, but it can't connect to the network. It does find the network and identifies it by name, but does NOT connect to it.

Sounds like a hardware fault Bob - Give it back to Rob!
or try and get HTC to fix if still in warranty?

Thanks! I thought so, too!

Hey did you solve problem?

*#*#4636#*#* choose radio off and then radio on, be sure to be in a location with a STRONG GSM Signal and your phone should connect. I have had the same issue with my Desire HD and have been surviving with this workaround as nobody else seemed to know

Stiill same :S Selected networkd unavailable error

Try changing sim, or it sounds like blacklisted IMEI.

But my sim works on other phones and other sim cards work on my Huawei?

I was reading through this hoping desperately that somebody had found a solution. I had switched to Cyanogenmod recently but had GPS issues, so I tried flashing a new radio and RIL. Now I can't make any calls/texts, etc. as described here.
Tried several other radios/RILs, tried nandroid restore, tried flashing whole new ROM (LeeDroid). Still the same issue. Tried the *# codes listed here, no luck.
Please let me know if anybody has solved this one. I really don't need a paperweight right now...

[Q] 3g Issue

I'm having a problem with my 3g connection since I flashed a new ROM.
I'm not sure if this is related to the fact that I'm using an unlocked Defy on AT&T. I won this phone a year ago, and I've been using it unlocked on AT&T since March with no problem.
I'm new to modding, but OCD about streamlining my electronics. My friend suggested rooting my device and flashing a new ROM. I decided on stock Nordic Froyo, and it makes me so happy not to see all the T-mobile crap in my apps tray. BUT the collateral damage is not so hot. I have no 3g or even 2g connection anymore.
I tried the fix in this thread http:// forum.xda-developers.com/showthread.php?t=944258 and was able to get a signal with 4 bars instead of the previous state of emergency calls only, but no letters like E or 3g and no ability to use the internet/transfer data. I also installed the broadband switcher in this thread http://forum.xda-developers.com/show....php?t=1052745 and tried all of the T-mobile US bands. No luck. I did reset the APN to default. No change. I've been using wifi, but will have to go back to work soon. Not having access to the smart part of my smartphone will feel sort of like having an arm cut off.
I'm not sure what to do next. I could try flashing another ROM, but from what I've read in the forums, that's no guarantee. If anyone has any suggestions to help a noob, I'd be forever grateful.
(And yes, I did first post this as a reply to another AT&T thread, but I think my problem is different than that OP's issue.)
Thanks in advance!

did u try the international baseband..

I just did. Same issue.
I've also tried the Argentine and Central American basebands. No luck. AT&T broadcasts 850/1900 while T-Mobile does 850/1700/2100, but 850 worked fine for the last 10 months. I don't get why things would fall apart now.

UPDATE: I was able to fix the problem by manually entering APN info. Am running on H now.
