I wanted to use a tmobile sim on my captivate, I know it won't get any 3g network but I can't even make phone calls or anything. The phone is unlocked and running fasty rom v2.0...any help?ideas?
Did you input tmo apn settings?
No but im not trying to get internet i just want to make calls
you turned off the phone , then put the tmobile sim card then turn it on . Make sure the sim card works and the phone is unlocked and you have coverage
Check the sim card is it working ? maybe a modem issue.

I have upgraded to your windows 6 and have a rom version 7.0c40CS, thank you its great, radio version 1.17.00 but my phone provider has now upgraded my sim card to 3G and now my phone does not work, it says no service available yet the card works in any other phone! I have carried out a hard reboot but still no good, can I use 3G? or do I have to go back and reactivate the old 2G sim card?
You are using a very old rom..try this version of the shekhar's rom

Right man! singjim may need to buy a new phone with 3G support then u can use ur sim card
3g simm card
Yes I need a 2G simm card, but when I got the old 2G card re-activated by the provider ( it works in other 3g phones ) I still have no service on the network.
I have updated the ROM as recommended by Ather90 and still it does not work. I have swapped the 2G simm card with a friend and tried his in my phone and it does not work! What a coincidence that my PDA dies when I change the simm card? I'm still lost help please.

Man! upgrade is not effect ur sim card, i think ur provider doesn't support 2G network anymore. I have upgrade my Xda II almost ten times already and it still working.
3g sim card
yes Iagree, I expect sim card is OK so what is wrong with PDA? Why does a reset as complete as a Rom upgrade not reset the phone?
This is the Same Problem i had with my Previous Himalaya..It always showed "Invalid SIM Card" or "No Service"...
i pulled out all of my hairs to solve that problem but it didnt...so i had to replace it...
Does your GSM provider still have their 2G network? If yes, insert your SIM to a SE phone and try it with 3G disabled (SE got a option to disable 3G & to use 2G only). If that also works, try a 2G sim of some other GSM provider in your PPC. Here we dont have to upgrade the sim for get 3G. we can still use the old 2G sim. But to have HSPA or speeds above 512kbps, we need to upgrade to a 3G U-SIM.
re 3g simcard
i use a 3g simcard using latest c_shekhar rom.. and it works.. no problem at all, only the stk doesnt work..
3G sim card
Took it to the XDA repair man who pulled a face at the cooked rom! then reloaded windows 2003 or something very blue and it all works!!! Plus 50$ for the trouble so I cooked it again to 6.1.2a16cs and everything is fine. It seems the phone operator deliberately immobilized the phone to make me buy a new one!! be careful out there.
Hi, all,
I have a quick question:
I was in Smith, Nevada recently, using a G1 with a Tmobile SIM card, and the phone did not get service. However, the phone did say that there was an ATT network present, and my friend's phone got reception just fine. However, when I tried to manually switch to the ATT network on my phone, I got a message saying that the sim card does not allow me to register on the network. How can I make the phone register on the ATT network when there is no Tmobile service?
Thanks,
Tekgek
Allow roaming? Best answer I got.
You could buy a cheap pay as you go att phone and swap the sim in yours.
Errrm, I think roaming is enabled. Is there a hack or something that can override the sim card's programming?
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

Hi,
I just unlocked my SIM card via a Verizon supplied code. I found an old AT&T SIM in my desk drawer - I called AT&T and confirmed the SIM is not active (nor has it ever been activated). I inserted it and the phone came up. However, if I use APN Manager, it shows I'm connected to Verizon. I'm able to make and receive calls.
I thought by inserting a different SIM I would be using that providers network instead of Verizons? Or do I need to manually change that somehow?
It's important I figure this out before my trip next month to Panama.
i think in usa the other network gsm bands are locked (so u wont be able to get service it wil just show no services i think) so even u insert them u wont be able to use that network ...
and u can change ur settings to gsm from mobile in network n settings i think..when u leave to panama or out of usa
hope it helps thnx
Hi, I just got the 8.9 3g Tab (P7300).
when I insert the Sim card to the device, it still shows "Please insert sim card"
and when I go to Setting, Network service. It tells me "Insert sim card to access network service".
I tested my Sim card to my Phone, it is ok. and i don't think there is anything wrong in the position of sim card when I placed to my 8.9 tab (metal surface face down)
I also did some research on the possibility of lost/corrupt data in EFS folder.
However, I saw my IMEI and Serial no is showing correctly (Not "unknown" or the default one). and I tried to odin the stocks 3.2 rom, wipe eveything. And i also tried to recover the nv_data files and do the chmod radio radio to that files under EFS. it still doesn't work.
does anyone here have some advise for me?
Thanks so much.
sounds silly but did you insert it far enough?
you really have to push down hard until you hear a little "click" the card then should stay in position.
did you install a p5 (3g) rom and not a p5wifi only?
Yes. the rom i flash is P5 3g room and for P7300 not P7310...
and I do hear the sound and the Sim card totally locked inside.
and I need to Push it to eject it out.
So i have no idea why it doesn't work.
is your phone 4g? if you insert a 4g sim into a 3g device it wont work. this probably isnt the case, but who knows....maybe they messed up your data plan and gave you a 4g sim for your 3g device.
did you get your tab from a carrier? did you buy it used and the guy before you had it from a carrier? if so maybe its sim locked?!
just guessing here though :S
How can I know whether my device has sim lock or not?
And how can I get it unlocked if so?
As my device is given by my fd so I don't know whether it is locked or not.
But I am sure it is 3g device instead of lte and my similar card is also 3g
