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..

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

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!

Hi Guys,
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
Matching radio and RIL as mentioned here: http://forum.xda-developers.com/showthread.php?t=1040986
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?
I have had that emergency calls for 2 day,s i am waiting only. Please help.

If you find that your GPRS data connection connects but you have no GSM signal do the following
*#*#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...

Trouble with Arc not connecting to mobile network

I have a recurring issue where my Arc when turned on does not connect to the network, no data and not even texts etc. Though it does display the network. I have to turn the Arc off & on again and usually after waiting a bit it will then connect.
The SIM card I am using is less then 18 months old. It looks in fairly good condition, apart from a slight bit of scuffing on the front.
So is it likely to be the SIM or phone causing this issue?

did u update to 2.3.3? before the update i had this issue for a few days where if i went out of a signal area and came back, the mobile network wouldnt connect. This was after I changed my number and got a new sim. I checked the phone information (dial *#*#4636#*#*) and found that mobile network displayed as unknown and only connected after I restarted my fone or by toggling airplane mode. The old sim worked fine though. Try to use a different sim and see the results. Its mostly the sim and/or the provider.

I have had it happen before and after the 2.3.3 update. One weird thing with this SIM is where in the settings it's supposed to display my number it has always come up as unknown.

its the same for every other smartphone ive seen. own number is displayed as unknown. try a different sim in your phone and try to adjust your existing sim and how its seated. my problem occurred for a week and for some reason, it went away without any reason. it wasnt tied to any specific firmware version. i asked the same question and it still remains a mystery. wait a week then see if you can get a new sim.
however, faster way is to enable airplane mode and then disable it instead of rebooting. this will get all your communications working. hope this helps
edit: oh and dont forget to hit thanks. i love being thanked. its my favourite thing in the world.

Nexus 4 No service

Hi, My Nexus 4 got no service already 1 week++. I already tested with the other SIM card and I also do a research on Internet. On Internet, also got many people faced this problem. On Internet, many people said the nexus 4 cant accept the SIM card that is normal SIM card cut into micro SIM card, must use the original micro SIM card. I also try with the solution and I bought a SIM card that is original SIM card but the micro SIM card also doesn't work. All the SIM card are cant detected by he nexus 4, will the Sim Card tray broken. My phone are protected by cover since day one and never dropped into water. I wish LG can fix this problem and help me to fix this problem, this really cause me a lot of problem. Regards, Tang.

check in settings if you have a baseband installed sometimes it uninstalls by itself so that could be the problem

Settings > About phone > Baseband version
Does the phone ask you to insert SIM, or are you unable to connect to your cell provider?
If you are asked to insert SIM, you may have a bad SIM slot (broken pin contacts), or the SIM is placed incorrectly in the slot.
If you just have no service, check your phone number is displayed correctly in "About phone" and try to scan for available networks in:
Settings > Wireless & networks (more) > Mobile networks > Network operators
then use "Choose automatically"

Will the sim tray broken. My nexus 4 is running JB Stock and no root.

Had the exact same problem. Had no service at all (the network icon was just a triangle), no baseband, no IMEI. This is what I tried so far. My phone was stock 4.3 before my experiments :
1. Tried toggling *#*#4636#*#*, tried all the options there - no luck. Radio was "off", and no matter how many times I tried to click on Turn On Radio, it wouldnt start
2. Tried switching Sim cards, from same operator and from a different operator, no luck
3. Did a factory reset using the settings menu - no change
4. Finally, rooted the phone using http://forum.xda-developers.com/showthread.php?t=2010312 (First time ever, complete noob here). Everything went smoothly. Installed all the standard stuff from the 4.3 image.
Now, I could see the radio intermittently turn on and off - what a relief ! Atleast I knew there exists a chance this is not a hardware issue. I was getting service for 10 seconds, then it was going off for 10 seconds. This was happening continuously.
5. Tried *#*#4636#*#* and toggling all options again, (even GSM only, WDCMA only, preferred etc). I am in India and using Idea Cellular.
6. Searched like crazy on the xda forum for possible solutions - decided I'll try out a different radio version (I had 0.84 on mine) from here : http://forum.xda-developers.com/showthread.php?t=2087227 - If you're a complete noob like me and dont know what the hell I'm talking about, trust me, flashing a radio is not that difficult. Just refer to my earlier thread link
7. Tried flashing each and every radio from 0.24 - 0.84. Mixed results. Except for 0.83 and 0.84 all other radios atleast maintain signal throughout. However it never turns "blue" - I cannot access the internet from my phone - I have a data plan, the apn information is correct and every other setting is proper (airplane mode off, data on etc). The other odd thing is I can call and receive calls, however there is absolutely no audio !
By elimination - I think there are only two options here - either this has something to do with the 4.3 update altogether, or this is a hardware glitch on the nexus 4 which is activated by some unique sequence of steps. Please note I did NOTHING "illegal" on the phone before this problem - no rooting no custom software, not even any apps which mainstream users would call "shady" - just the usual FB, Mail apps, my corporate mail account.
Any ideas here - I am going to go ahead and try flashing my phone back to stock 4.2.2 again, and hope that works !! Please help ! And apologies for the tremendously long post first up

NoobNexus

In the off-chance you might still read this: I'm having the same problem, just as some other Nexus 4 users: http://forum.xda-developers.com/nexus-4/help/nexus-4-service-t2501076/post61681896#post61681896

i recently buy a nexus 4 from ebay, only for nostalgia, so, when i receive the cellphone, i turn on without a sim inside, connected to wifi and the phone request for 3 upgrades of security, the nexus was in 5.1.1, the last than ir support, so i accepted the upgrades and the nighmare start, when i put my sim, the nexus not recognized it, i try everything, put in airplane mode and back and nothing, full reset from recovery twice and nothing.
So, i unlock the bootloader, install a recovery (clockwork) and root, after download from google the formware 4.4.4 for nexus 4, start the downgrade, when my nexus wake up in kitkat with my at&t (mexico) sim inside, the same problem, still not detecting simcard, i connect to wifi and the cellphone request for an upgrade, android 5.0.1 , click in next and the nexus start downloading and installing the upgrade, after 15 minutes, again with the sim indide, wake up with lollipop and the signal come back again ¡¡¡¡¡¡¡
My nexus after 24hrs is still with signal, whitout problems, but still request for the other 3 upgrades ( android 5.1.1 and other two upgrades for security), but with previous experience.... i will keep in 5.0.1......

NO 4G on any sim

Evening all.
I have a Nexus 6P which i used on o2 4G for 2 yrs straight without any issues, when i got my new Pixel 2 i put it away for future use.
I have now come to use the phone as a works phone also on a o2 sim 4G sim but cannot get any 4G on the phone, yet i can make and receive phone calls just fine.
I have tried the works sim in my Pixel 2 which works fine and also tried my personal sim in the Nexus 6P which doesn't work.
I have tried various different APN settings plus as it would be a company sim i have tried various ip addresses as well.
Last night i rooted the phone and loaded TWRP recovery done a backup and loaded resurrection rom but this has not worked either.
Has anyone come across this issue before? if so have you managed to resolve it?
Also
I read somewhere about something to do with baseband modem but cannot find it anymore is this something i should be looking into?
I would appreciate any help there is.
Thank you.
