I'm currently in Taiwan for about a week, and am trying to use my T-mobile SGSII with a Taiwanese SIM card. I got my phone unlocked before I left, and I'm not getting any errors with the SIM card. However it looks like it's not working. I'm not seeing any network signal. If I try to search for a network it says "Error while searching for networks". If I try to select a network automatically, it says "Your SIM card does not allow a connection to this network."
Anything I'm missing?
Thanks!

Well I eventually gave up on getting the Taiwanese SIM card working, but now I'm back in the states and my phone can't seem to recognize my original T-mobile SIM card anymore. I can't get any sort of network connection, and I get the same error messages when trying to change the network settings. Wifi is working fine.
The SIM card is fine, because I popped it into an old unlocked dumb phone I had, and was able to make calls with it... any ideas?
Thanks!
So it looks like my phone is stuck in flight mode, although Wifi works. When I goto Settings > About Phone > Status, the Service state says "Radio off"...

Hi there,
I'm on vaca for one month in Africa and I am trying to use my sim card but I have this message :" Your SIM card does not allow a connection to this network "
I tried two different sim cards but I still have the same issue.
Note that the phone was working perfectly yesterday with my Tmobile Sim Card.
It's an international One X so I don't think that I need to unlock it.
Do you guys have any solutions?
Thank you
it sounds like something tmobile end has changed on your account, if possible i'd call them to see if they can help get it working again
other thing to check is the roaming settings, check its enabled etc
Thanks for the reply.
I'm not using that Tmobile sim card anymore. But an Orange one.
Should I factory reset it and see if it'll work?
Thanks
i had this happen on mine, ive got tmobile sim, it went to tmobile orange signal, i tried to manually switch it back to tmobile (better signal coverage) and it said the same thing.
A reboot didnt fix it so i went into settings, storage, make more storage and then cleared all temporary data for all apps.
this seems to temp fix the issue and allows me to reconnect to my peferred network it still happens every now and then so it could be a software gitch with the hox
Just tried it. Didn't work
I will restore it and see how it goes
Even with the New Rom, Superwipe I still have the same issue ?
i have the gt-i9250 and i always used an at&t sim with it with out an issue, recently i wanted to switch to t-mobile (thinking the phone should be unlocked considering it was an international phone and was the yakjuxw than i flashed it to yakju which was wierd cause i had google wallet on it and it was working fine although i only thought it was compatible with takju, but anyway all and all i put it to the usa firmware of takju 4.0.4 not going to jellybean yet, but my issue is that i am not able to use the t-mobile sim card in it and i get this (look at screenshot where signal is) what does this mean and how come i cant get signal, when i go to settings and mobile networks it shows me the apn for t-mobile us but not selected so i select it than after i go to mobile networks and it shows t-mobile and at&t and when i click any of them they tell me its unable to connect and it cant connect to the network at this time, so what would this mean and how would i fix it so that i can use it with my t-mobile sim card, also i flashed the newer NA radio uglc1.
That is weird. It should work on either of them. It just means you have no signal. That is strange. You could've actually just popped the Sim right in. It didn't matter if you were using a ROM

Is the SIM activated for sure? I know when I switched to the T-mobile $30 plan it took it a good 15 minutes or so to activate, and then I didn't actually get signal until rebooting the phone for whatever reason.
Did you reboot your phone?
Although you can sometimes hot plug a sim card by turning on flight mode, taking the sim card out and toggling flight mode a few times, it won't work sometimes.
probably your cell imei not free and therefore can not change your sim.
There is an application called "****docomo" worth to release the imei. Make a backup just in case

Don't think he has a SIM unlock problem. Considering that it was working with AT&T, which never had a locked version of the GNex, I think he's having another issue.
I'd tell the OP to make 100% sure that his new T-Mobile SIM is activated and not defective, then try a few reboots and swaps back to the old SIM and do some troubleshooting. If it's the phone and not the SIM, its likely a mobile network registration error or an APN issue.
Looking in the notification bar, it seems like the phone doesn't think there's even a SIM inserted. Make sure you didn't damage a pin in the SIM tray, and that the SIM is properly inserted and clean. I don't think you'd get this error of "no SIM" if your phone was locked. If that was the case, the phone would recognize the SIM and prompt for an unlock code, which you're not getting.
Hi,
I recently went to India and thought it would be cheaper there to get my note 2 unlocked but, the person who tried unlocking my device got mad at me as my phone was rooted. He said, everyone wants to be a developer nowadays and thus it made his job harder. He asked me the model number of my phone as it shows GT-N7105 because I have DN3 v 5.2 installed but it is actually sgh-i317m from Telus in Canada. He gave up and said he was unable to do it. After coming back home, my original sim that I have been using in the same phone, does not work anymore. There is no network. My wife's sim card, which is from another provider, works now though it never did before. I though there could be something wrong with my sim card so I tried it in an old phone and it works perfectly in it. What would you suggest, I should do to try and resolve this problem? I am thinking of erasing everything from my phone and factory resetting it. Eagerly waiting for your expert suggestions!
Just to add: I chose factory reset option from under the settings menu and wiped all my data but it still does not work with my sim. I also, went under the available networks settings, chose the option to search networks and then selected mine (telus) but it say's no service (telus) not available. There is another message in the notification bar, which reads "data roaming: You have lost data connectivity because you left your home network with data roaming turned off". I am not sure if that tells you something related to my problem but I though I should mention that as well.
Hey guys,
I've got a problem.
My s4 mini stopped loading cell signal from GSM network service. The SIM is loaded, as I can see it even in some programmes like Network Info. It even shows the name of the operator.
Even though the SIM card is loaded (it does NOT show "no sim card" error), I cannot get any service. Used 2 different network service providers, but still nothing. I changed GSM antenas and also SIM+SDcard slots on the motherboard, but still nothing.
What can the cause be, any idea?
Thanks.
So I have the Galaxy S9 plus, sprint edition. I flashed it with the U1 firmware. Then paid to have it network unlocked. It was reading every SIM card, but sprint & boost (bcuz to get are n not compatible with the unlocked SO/S9+.
So, I decided to switch to either Verizon or AT&T. Verizon won it due to the year long Subscription. Anyway before I went to Verizon. Every SIM card I placed in the card worked no problem. Well, Verizon activated the phone told me the steps to do. I powered off the device. Like I was told & placed the new sim card in.
When I booted up my device it, rebooted with the "New Network provider Sim inserted" & did so. It came on with service. Then rebooted again & came back on with service... Yet again. Then out of nowhere it rebooted, but this time it came on with it any signal bars. Saying, the folowing messages "Searching For Service", "No Network Connection" and "Emergency Calls Only".
I have did all the trouble shooting that I have came across. Including using the Chimera Tool to try & fix the network connection. But it repeatedly failed. I took it to UbreakIFix & they said the phone's fine. That it has to be Verizon's side with the problem. Can anyone help me fix this issue.
I have placed other Sim cards into the device & they work but not one Verizon Sim will.
