[Q] "Your sim does not allow connection to this network" error

Bought a Galaxy S yesterday. It is originally purchased in the Netherlands, but i'm using it in Belgium now. When buying it, the device got tested with proximus and mobistar sim card (main providers in Belgium) and seemed to work (sms and calling worked). Getting home, putting in my mobile vikings sim card, I didn't seem to get any service. In my notifications bar it says BASE (which is the network mobile vikings uses if i'm not mistaking), but i'm not getting anything.
When searching the providers, mobile vikings is shown, but when selecting it I get :
Your sim does not allow connection to this network"​, which is strange since it's a mobile vikings sim card.
Never had any troubles, and sim card was working moments before testing on the galaxy S
No custom rom installed or what so ever.
Any help would be greatly appreciated since I can't do anything with the phone atm.
Thanks in advance!

I had this problem about 8 months ago... If i remember correctly I just had the wrong modem flashed... I was missing a modem with 850 band... try flashing Ugkc1 of jk4 modems... also check to see if your APN(access point names) are in your wireless settings

Just got a mail back from my provider, they're sending me a new simcard. But I doubt it's going to make a difference...
My apn settings are all ok. Don't know about my modem though...Don't know what it is, or whta it's supposed to be

I am pretty sure you probably need the 850 mhz modem in your area then..
what is your current baseband (settings>about phone)
New Sim card won't fix your problem.

My baseband is XXJG1, and I'm still on Android 2.1

My suggestion to you would be to download JS8 which is 2.2 and flash it with ODIN
http://www.samfirmware.com/WEBPROTECT-i9000.htm from here (you need to sign up)
see if that fixes your problem...
if it doesn't work, stay on JS8 and flash a modem(phone) file only that has 850 enabled... like JK4 or KC1 (there are more then those 2)
Just look up steps on how to flash with ODIN and check you tube for videos... just be careful...

Thanks a lot for the advice. I'll try it this weekend. (on a mac atm,and can't get heimdall to run)

UPDATE:
I tried flashing my modem without any result as far as I could see. Tried flashing darky, without result.
Got my new simcard from my provider, but nothing . I'm back on stock now FW 2.1 update 1 and baseband XXJM3.
Strange thing is that I get edge and 3G, to which I can connect. So my mobile internet from my provider is working, but no signal what so ever...
I'm starting to get desperate here...

I was also similar problem on my i9000t and i897 used in India. In my case the problem was intermittent. The solution i arrived at is as follows:
First select a modem that works correctly for your Band. Now force that particular band from SGS tools or going to service mode by dialing *#2263#. For example I force GSM900 for edge and wcdma2100 band for 3G. After that let your mobile choose select the network. Be patient for 10-15 minutes, it should work.

[Q] 850mhz band broken on my phone? (''Unable to connect. Try later'' got me crazy):

Hello guys! I've been reading these forums for a long time, amazing what you guys do in here
Here is my problem: I live in México, and I traveled to USA for summer vacation, my mexican mobile phone carrier uses 850mhz (TELCEL) and when I went to USA it was using ATT's network.
So everything was working fine, but when I returned just before I was about to cross the border, it stoped working!
It has a message that says ''Emergency calls only'' where it's supposed to say ''TELCEL GSM'', so no internet, no calls, no messages.
I was using Froyo on my phone, and thought of doing a reset to restore factory settings on the phone, but it did not work :/
Then I updated my phone to Darky's Rom 10.2 (Gingerbread) and it's still not working!
When I go to Settings>Wireless and network>Mobile networks>Network operators I can see that my carrier is available to select, but when I try to, it gives me a ''Unable to connect. Try later'' msg.
It is really frustrating because I depend on my phone so much, mainly because I share my 3G connection to my laptop for school's work and stuff.
There's one weird thing though, I unlocked my phone, and placed a MOVISTAR(1900mhz) SIM card on it, AND IT WORKS!!!
But the thing is that I don't have internet on that SIM card(is prepaid and it's EDGE, not 3G), and on my TELCEL SIM card I have a contract to complete (still a year to go).
When I put my SIM card on someone else's phone, it works like a charm, but if I try to put a TELCEL (850mhz) SIM on my galaxy; just says ''Only emergency calls''
What do you guys think happened to my phone? I would really appreciate your help.

flash a new modem... one that contains more frequencies enabled.. any bell or telus will do.
UGKC1 modem should fix your problem.

It did not work, should I keep trying with other modems?

you can.. jk4 or jl2 are other modems with 850 and 1900 enabled... maybe your problem is different then I thought... but it sounds like your modem... maybe try unlocking your phone? if you can connect to wifi download sgs unlocker pro (paid app) in the market to unlock, your phone also needs to be rooted. are you using the i9000T? that may be different problem altogether...
edit: sorry I see you said it is unlocked... just doesn't sound like it...
a) modem related (ugkc1) should have fixed that
b) SIM carrier not compatible to phone (unlock phone to fix)
c) Busted SIM card, check in other phone
d) make sure phone option is set to Automatic CDMA/GSM
sounds like you checked everything I would check....
does your 3G work... make sure your VPN is setup to your carrier

maybe imei got blocked...? only way around that is to get provider/samsung to unblock

Hey have you solved this, I have the same problem

No T-Mobile network

I took my girlfriends S1 on holiday with my 3 network sim in it, when we came home I put her T-mobile sim back in, now it will not connect to the T-Mob network, it will connect to 3G? Putting the sim in my SNote and all is well. I have since install a custom rom to see if that would help but still no good.
Galaxt S1 running CyanogenMod 10 nightlies.

Believe me I have taken the sim out and tried it in the "wrong way" lots of times. I have also looked at your solutions page before, very helpfull. But why will the sim work on one network but not on another, and the non working sim will work in another phone????

Check the modem on both phones.
If the phone that doesn't recognize T-mobile has a different modem, then load the modem that the phone that works has through oden or CWR.
Hope you know how to check the modem and load new ones.
Good luck

This will happen as T.Mobile may be using a different Radio band ..most likely you changed the APN and Network settings when you used it with another SIM Card , whilst abroad ...all you may had to do was check your Network Settings in menu> settings>wireless and Networks> Mobile Networks and reset it back for the T.Mobile network, initially
To understand this better read this http://en.wikipedia.org/wiki/UMTS_frequency_bands
at the same time since you upgraded by flashing to JB, you may have to select a new modem that is suitable for JB, you will find all modems at My Android Collections

Data but no calls
Me back again, I have tried all xx modems, reverted back to stock rom, then GB, them back to CM10. When I first turn on phone it finds network (i'm on a giffgaff sim now) it says GiffGaff at the bottom of the screen for about 2 seconds, then it says emergengy calls only. I can still connect to internet. APN settings correct, IMEI correct, In Settings - About Phone - Status, i'm connected to network, service status = out of service, mobile network state = connected, my phone number = unkown. Where can I go from here?

More
Another thing I have just noticed, when I take the sim OUTwhen the phone is still ON, the "no network" on the screen turns to giffgaff,

Try to set your phone number by following this guide , it was written for a Korean version, so just adjust it for your phone version.

How did you get the SIM unlocked in the first place?

This is probably because T-mob covers only particular places the frequencies this phone uses http://theunlockr.com/2013/07/05/htc-one-sprint-specs/ vs t-mob https://t-mobile.jive-mobile.com/#jive-document?content=/api/core/v2/documents/4988

Is there any solution for this problem ?
Is there anything I can do to fix this problem ? (different rom or radio...etc..) Or I have to give up the phone... Cause it is too much headache to "searching for network" all the time and miss all the call with no service on the phone without knowing..
Thanks

well, I am not an expert on the tmobiles network, but going by what lazybozz, said, I seem to remember tmobile using different bands than the other carriers, so what you may be experiencing, is the phone being in the vicinity of multiple towers, but not all of them are within the band that the phone supports. So its like the phone doesnt even see those towers. On a side note, this issue caused alot of chaos for those who unlocked iphones about 3 years ago, they could use EDGE on tmobiles network but not 3G, so i assume this is a similar situation. So long story short, yeah you probably cant fix the problem, unless you get a quad band phone. I could be wrong, but it does sound like a logical reason for the issue you are having.

as elvisypi said above, Its the freq that T-mobile operates on in that area. If your getting T-mobile at all in the states then you have already flashed a radio. However flashing any other radio is not going to give you the freq that tmobile uses, Its not a software limitation its a physical hardware limitation.

Thanks for your reply, do you know any app out there that monitor and alarm you when the network or signal is lost ? That works with 4.3 ?That way at least you know the phone is offline ... some of the apps I tried is anything at all ...
Thanks

Have you tried an app like tasker? Its essentially an automation app. It isnt jist for your use. Its for many different functions. Jist look on the app store for tasker. That might help

Droid 3 not working on T-Mobile

I recently sold this phone to somebody on T-Mobile, but they're getting this message "no GSM/UMTS networks were found". The phone worked perfectly on AT&T and has the build.prop edits. I really don't want them to have to return the phone since it was working fine, so does anybody have any idea how to fix this?
It obviously has the XT883 radio. I tried using my mother's sim card in the phone and I actually had the same issue, but upon putting in my own AT&T sim it stopped having this glitch. I figured since the phone was working on GSM it was just an issue with my mother's sim, but I'm completely lost as to what to do to get the phone to find the T-Mobile network. I've already tried manually connecting to T-Mobile 2G and 3G in the network settings, but this didn't work. Factory resetting and reapplying many different radios and different build.prop edits also didn't fix this issue.

thats strange . i sold a droid 3 flashed with the gsm radio to a guy using tmobile and it worked fine,only issue was in the area we were in,tmobie wasnt running on 1900mhz and he only had EDGE.
did you try to SBF the phone and repeat the procedure completely? maybe he messed around with something in the root manager.

If you did your sim unlock with an AT&T SIM, more than likely they would need to repeat it with a T-Mobile SIM as it usually adds that carrier's SIM cards to the white list.
