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..

[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.

[Q] No connection for calls/SMS but data works?

My SIM unlocked Defy has been sitting unused on the shelf for several months - I did plan to sell it after upgrading to an Atrix, but never quite found the time to sort it out.
I've now decided to pass the Defy on to my girlfriend as a Christmas present (yeah, I'm a tightwad ), but have not been able to get it to work correctly.
The problem is this. The Defy will not connect to the network to send or receive calls or SMS messages. However, the phone can connect to data services via 3G (even though, on my Giffgaff SIM, it gives some sort of error message saying connection will not be possible, before accessing the internet without problems!).
I've tried:
Multiple Basebands - including the various ones I used previously without any problems.
Multiple ROMs - CM7, MIUI, WajkIUI installed via CWM and a couple of Froyo SBFs installed using RSD. All these ROMs show the same characteristics - no calls or SMS but Data connections work.
Multiple SIMs on different networks. The Defy was originally a T-Mobile device but I unlocked this using a code from one of the Unlock sites and used it with an Orange SIM then my Giffgaff SIM with no problems. Now, the very same Giffgaff SIM shows the call/SMS problem. My girlfriend's T-Mobile SIM appears to be recognised normally and the network seems to be working but all calls and SMS messages fail instantly.
Multiple Wipes/Resets using both CWM and the stock recovery. None has resolved the problem.
A quick Google found the following link:
http://thewichitacomputerguy.com/blog/how-i-fixed-your-sim-card-does-not-allow-connection-network-g1
Unfortunately, I've tried everything recommended on that page without success.
Anybody have experience of this problems on their Defy and, if so, can anybody tell me how I can fix it?
I promised my girlfriend a phone so, if I can't get this Defy working properly, it's going to cost me a few quid so I would appreciate any assistance!

I've since discovered that my problematic Defy appears to have been blacklisted, almost certainly by accident by those wonderfully incompetent folks at Orange. Here's more information on a problem which has occurred with quite a few people here in the UK following the merger of the Orange/t-mobile networks in mid-December:
http://forums.moneysavingexpert.com/showthread.php?t=3677593
I bought the phone on eBay from a seller and used it for around six months without any problems so I think it incredibly unlikely that the blacklisting is valid - I mean, who would report a phone as stolen around 8 months after it was taken?!?
Just waiting to hear back from the eBay seller to see if he can provide me with his original proof of purchase for the phone so I can get the blacklisting lifted. I don't rate my chances all that highly.

Hi all. sorry to revive a few month old thread, but at least I'm not creating a whole new one!
I have a Motorola Defy. Generally I'm pretty geeky, but I decided to root it at install ICS 4.0.4... it all went well... eventually. However I have no conectivity to my network. It will not send or receive texts calls or data to the network. Wifi does work still.
Honestly I'm done screwing around with it. I just want to restore it back to original factory settings and admit defeat. Where can I find the original firmware that will work In canada on the Telus network? This is my only phone, I have no other cell and no landline so I'm kinda in a pickle and would appreciate anything you could do to help me get up and running again.
If there is any more info you need just ask, I'll try to get it for you.

Try it with this baseband switcher. Maybe it will help you.

Thanks! I actually just saw your post, but I figured that out all by myself! It did work though! I appreciate the reply!

ok new problem... everytime I shut off my phone it reverts back to the wrong baseband. any idea on how to keep it on the new one? every time i reboot I have to swithc baseband then do a restart. it them switches and works perfect. If i shut the phone off it reverts and I have to go over it all over again.

Try to convert defy baseband switcher to a system app with Titanium backup.

Thanks Vicsa! Used Apps2ROM (ROOT) instead because I'm cheap, but had the same effect. You sir are awesome!
And now that my phone is working again perfect I'll be leaving the F***ing thing alone now unless i'm absolutely 100% sure what I'm doing. Generally I have no issue doing things like this to computers, but it would seem that phones are a whole new breed... Anyways THANK-YOU!!!!

You're welcome mate. Glad I could help you

No 3G signal at all, but not quite the same

Hello, first to say, im not a newb, noob, newly registered, or a guy who dont understand anything from android.
Im not posting stupid topics, or topics which answers can be found easily on internet/google/xda/forums and such.
I am running stock rom, only rooted (i used to root it only to apply some xposed settings and clear some unnessesary apps, nothing more, nothing less).
Here is the description:
My phone has no warranty, i bought it online, brand new from UK, simfree. At that point, i had no problems with the connection. i received OTA Update - about 50-60 mb, but the phone remain 4.2.2 as it was. I still had no problems with the connection. After some time, the phone was left alone inhome for a few days, may be a week, it was turned off and it was not used at all. When i got back, i inserted my sim card, and i saw it is showing only G icon, and no 3g/h/h+, nor even 2g. I live in big city with very good network coverage, so its not network problem. I dialed up the customer service (Globul Telenor Bulgaria) , explained them my problem and asked them to check if its operator's problem or sim card problem, but it is not. The sim is fine, so is the network coverage. I dont have other operator's sim card to check the phone. I tryed several possible solutions found in google/xda - turned off the phone, removed sim and battery and left that way for few hours, still have the problem, tryed to switch operators manually and register sim card to other operator then back to mine, not working. Several times reseting/ deleting APNs, switching airplane mode, data off/on, adding apns/searching for networks and all available combos, not working asked Globul Customer support to send me new settings- not working. The only obvious thing i havent tryed is the factory reset (I still need to do a backup first and dont have time to do it right now.)
In Settings- More networks - Mobile networks- Network mode i have 2 options - 2g/3g auto connect and 3g Only. When I choose only 3g - i lose any signal, like there is no sim card. Reverting back to auto 2g/3g is registering my sim back to Globul network.
Then i decided to root my phone if i can find a fix for the connection. Rooted with CF-Auto-Root thru Odin. (The 30sec Root)
Looked for some tweaks in xposed modules and settings, i couldnt find anything related to 3g. Still looking for a solution...
I repeat - my phone was completely stock and non-rooted when the problem occurs! Now is rooted with stock rom. (this is the diffirent from every topic i searched.)
Im attaching some screenshots, if someone can help me. 2g is really annoying and slow as hell.

Well the first thing I would do is update your phone. You are running 4.2.2 which is old. Update to the latest version, that could either be a stock rom or a custom rom.
After that do a factory reset. Make sure you backup your internal storage etc, because it will wipe it clean.

Factory reset, updated to 4,3, after that 4.4.2 problem still persists.
No 3g at all. Its not the sim. Any way to fix it ?

Soo no way to fix it? Should i give it for repair?

Please help my Verizon LG V20 not getting any cell ID's

#1 phone in on verizon network thru PagePlus
Please read my short post carefully and try to respond with a solution, for it may be effecting more then me. Thank you.
About 1 month ago phone would stop responging to apps requesting cell towers ID.
It was gradually getting worse.
Today what ever app i use, not one of them is able to get ANY cell tower names/ID anymore.
Phone is on 13A rooted via dirtysanta method. (does not matter, it does not work even if not yet rooted)
I tried reset the phone. Reflash firmware. Wipe cache/dalvik you name it.
I tried installing NO OTHER APPS and just install one app specifically to read cell towers and its not working.
So clearly, apps are not to blame.
I tried using Verizon simcard and my own tracfone/pageplus no change.
I tried upgrading to original firmware 15A, no change.
Problem started creeping up slowly and now its a constant issue.
Can someone help me with that ? What can i possibly do to resolve this ?
Thanks guys.

But are you getting data? Can you use Verizon data to browse online etc? Did you try a different sim card?
