[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] i9000T on Darky ROM 10.2.2 problem with 850 band

Hi!
I have been searching hi and low on how to recover my 850 band.
I bought in June of this year a SGS I9000T on my country, approved by the SUTEL which is a government bureaucratic branch that has the purpose of making sure the cellphones brought to the country can be used and blah blah. I currently live at Costa Rica. It was working perfectly fine up until the point in which I changed it CWM 7.0 and lost my 850 band. It was under 3G coverage.
During the installation my phone got bricked and I flashed several other firmwares where I had the i9000B and i9000M and i9000t, but in none of the aforementioned I got 3G coverage anymore (including i9000t).
I finally went to CWM and got tired of it. Eventually, I got back onto searching on this subject and found how to enter the service mode, got into *#*#4636#*#* to find I was on EDGE, then on *#2263# and activated my 850 band, with no result. It was active, but it wasn't ever actually used.
I changed my SIM Card three times making sure it had 3G coverage, I also changed carriers to find the same.
A friend of mine bought a i9000T and had perfect HSDPA coverage, paying the same as me, with the same data plan, under the same company.
I thought it was the ROM so I moved back to stock FW and had the same results. On each one of them I activated the 850 band and got the same result -- no 3G coverage.
Then I tried Amestris 3.3 and the same.
Then I went to Darky ROM 10.2.2 with the same result. I learned about flashing different modems, and have done so for the following:
TUBJV6
JVO
JPO
JPD
I am currently using TUBJV6, which is the same of my friend's.
My screen shows up the following under *#0011# command:
GSM: HOME(CS+PS)
Band: GSM1800, BSIC: 55
Reg PLMN MCC (712)-MNC(1), IsPCS
TchFrq: ,BcchFrq: 556
RSSI: -73, RxLev: 37
NOM: 2, TxLev: 255
TS: 0, VocType: 255
Cell_id: 10813, LAC: 5112
On *#2263# I have tried to leave it only to WCDMA 850 band but got no service message or emergency calls only.
All the Combi bands are active, including 850, of course.
I don't have a backup for the first ROM I used to have, but it was JPD and I tried it with no result.
Any suggestion? I am literally going mad over this problem.
Thanks in advance.

this probably doesn't help much, but I flashed darky's 10.2.2 today on a i9000t (venezuela, 850mz) coming from stock froyo 2.2.1 and I can still get 3G and H (which should be enhanced 3G, or 3.5G)
Also, I did not flash any modem other than the one that comes with darky's.
Baseband: JVQ
Also, make sure under your network settings you have your APN set correctly for your carrier! Although, if you can get EDGE, most likely you have them set correctly and your problem is not related to APN. But it's worth a shot. I know that by flashing other roms, the APN info is lost, most of the time.
Good luck.

bro,i facing the same problem with you!!!!
no 3G/HSDPA connection at all!!!! only connect with GPRS and EDGE
i just subscribe my data plan before flashing darky rom !!!!

[Q] Galaxy tab 7" not getting tomibile 3g

Hello,
I have a galaxy tab non branded with overcome installed.. I`m trying to get Tmobile 3g on the tab but no matter what modem i installed i`m always getting edge.. I tried with roto modem switch.. but still no 3g.. Tried to flash with tmobile stock modem but no 3g..
Model number GT-p1000M (SGHI987)
Firmware 2.3.6
Baseband T849UVjjB_ROTO-3G (after useing roto modem switcher)
Kernerll 2.6.35.7
Overcome-v4
I have tried the froyo, gingerbread now trying it to get 3g on overcome..
Please suggest me if i have to make any other changes to get 3g on tmobile network..
Thanks

bell mobility tab no 3g on tmobile
No one is having this issue ?

No 3g, just Edge signal
I too have a similar problem with no 3g signal. I'm in Bolivia and I have 3g coverage with my provider. I had upgraded to Gingerbread in hopes this would solve the problem. No 3g. I then installed the different modems and I still had the same (no 3g) problem. After this didn't work I went back to Froyo as a last ditch attempt since I had rooted Froyo in the beginning and thought maybe something got messed up. I've never seen a 3g signal here and don't know about the U.S since I've only use it here. Is it possible that the Galaxy Tab 7 3g just does not work in Bolivia? By the way, I've checked all settings and done everything to make sure things are correct. Any ideas? Thanks.

for @polapine, this is answered in another thread.
Basically the conclusion is that T-mobile uses different frequency for 3G/HSDPA, that a normal unbranded tab modem hardware is simply incapable of using. (1700 Mhz)
On the other hand, a T-Mobile branded tab can also operate at the "usual" 3G band in other networks in Europe/Asia/Australia (2100 MHz)

What modem should I use for my galaxy tab 7?

I have a galaxy tab 7 from T-mobile. I have updated my firmware to newest overcome rom but I don't know what modem I should use for it. I live here in the Philippines which is part of Asia. I want to use a modem with call and 3g function. Additionally, when changing modem, will it wipe out my system? Thanks in advance.

I have the T-Mobile SGH-T849 too.
Use JPZ modem in Asia/Australia/Europe should be fine.
No, flashing modem will not wipe your system.
After flashing go to setting About Phone and check your baseband
it should have changed to something-something-JPZ

yup, I'm using JPZ on my tab, but I don't have 3g.. i only have edge.. can I still revert back to having 3g instead of call?

which network in the Philippines? maybe we can find out what frequency your network use.
It is weird. I thought asia uses GSM 900/1800MHz and HSPA at 2100MHz, which is what the JPZ does.
The original modem (JJB) can be found here.
http://devphone.org/files/gtab7/modems/
But T-Mobile modem is meant for T-Mobile user to have 3G, even them won't get voice call with it.
Are you sure your area has good 3G reception?

I'm not familiar with frequencies and such, but i'm using Smart here in the Philippines. Can you help me determine what network I should use?

http://obsessivecoder.com/2010/09/19/philippines-gsm-frequency-band/
Smart Communications 900 MHz/1800 MHz W-CDMA (UMTS) 2100 MHz
Exactly the same as other GSM I know in Singapore/Indonesia/Australia
Can you check your setting just to make sure you are not restricting your wireless to 2G only?
EDIT: I am not sure if you edited your post. But I thought I read you get E only.
Now I can't see any of that in your post.
Do you get mobile network working at all?
If not, then the issue is with your APN.
You need the right APN for Smart

i've set it on wcdma but it does not pickup any signal. i still only have edge.

Menu -> Settings -> Wireless controls -> Mobile networks -> Uncheck .. only 2G
I got more info on APN:
APN Settings for Smart Bro
Postpaid APN: smartbro
Prepaid APN: smartbro
APN Settings for Smart Buddy, Smart Gold
APN: internet

i'm still on EDGE.

Last try:
http://androidforums.com/samsung-ga...rk-frequency-your-samsung-i9000-galaxy-s.html
forget about the references to 850MHz,
access the menu and make sure you have stuff selected for 900MHz 1800MHz and 2100MHz
normally we have 3G on 900 and 1800, and 3.5G on 2100MHz

still not working

you can confirm that the same SIM card in other phone, at your present location, gets 3G?

yup, on my galaxy y, 3g is ok

and APN in that phone is the same?
EDIT: try other modems. KM2 for example

went back to t-mobile modem for the mean time. will try out km2 later. from the modem list, most of them are for gingerbread 2.3.3, but mine is 2.3.6. will there be any conflict with that?

nope.
even froyo modem works.
we use JPZ through to ICS as well.
Does T-mobile modem gives you 3G?

yup, it gives me full hsdpa connection speed.

hi mahan21,
Not sure if you are still looking for the modem.
try T959UVJL5 modem from the Galaxy S T-mobile.
I was baffled because I am really sure I get 3G/H on JPZ but I check again I can't.
I even restock to GB stock safe, no luck.
So after searching, I found the JL5 modem
and it works!
3G/H and voice call on T-mobile tab in Asia (Well, Optus Australia but it is the same GSM/UMTS combination)
Get the modem here:

i9000 cannot make or receive calls. modem problem?

Hi everyone, noob here so dun wanna start a new thread with my question since it is related to this matter and I was wondering if anyone can help me because I really can't figure it out anymore.
I have an International GT-i9000 purchased with Hong Kong and system specs I have running are
Gingerbread.ZSJW4 (recently flashed the official ROM from Hong Kong cuz I am anal and want to keep the same languages)
Kernal: 2.6.35.7-I9000ZSJW4-CL1147074
[email protected] #2
Bandbase version: i9000ugkg3
And I use AT&T in New York (I know, worse plan to use in dead zone capital of the US)
I had flashed the ugkg3 modem on it because the JW1 modem that was with the official ROM wasn't working out for me and I had heard this modem was the best for my area. Before it would either not pick up a signal when coming up from underground or the signal just go dead, which did not happen when my phone was on Froyo (on Froyo I did not have 850mhz enabled and it worked alright outside and sometimes in the house)
At first, the KG3 modem worked wonderfully, I was able to receive data in my house and was on 3 bars (compared to none to one before). However, I now notice that while I do have full bars, I cannot receive or send messages or phone calls (even though my brother's Note is able to do all that and it was next to my phone).
I also happens when I am outside as well.
The other day I was standing in front of the AT&T store near where I am and I still don't pick up a signal.
Or it would lose the signal and never pick it up again.
Unless if I really can't use 850mhz on my phone, which does not make sense because AT&T uses 850mhz.
I am real hesistant to try another modem, and I cannot figure out if it is a hardware issue or network issue, or is it just the wrong modem?
Can someone please share any insight?

my other question is, phone is not ICS, and I found the nexus S one...will it still work?
and can I just extract out modem.bin and flash via ODIN ?(somehow my phone won't do CMW recovery...)
