hi guys, i've been having a problem about my network. sometimes my data isn't working at all but it doesn't really says that it's disconnected to fix it i have to reboot. I tried different roms but my data still drops sometimes like 4 times a day.
so is there any chance that i broked the phone's data antenna even my calls still work? i have the phone for 6 months and this is the first time this has happened. i really don't want to exchange my phone to tmobile but if that's the only way to try then that's what i'll do.

I would suggest getting a new SIM card. In most cases a new sim card will fix that problem. I work for T-Mo and that's usually a good fix. If that doesnt work then try a factory reset. If that doesn't work then warranty. Good luck!!

yeah i have done a factory reset. So i'll ask t mobile for a new sim card?
Sent from my SGH-T959 using XDA App
Just go to a store and ask for a sim replacement. Since its a damaged sim they should just replace it for free.

I don't need to call them? i'll just directly go to a tmobile?

Yes sir. They will activate your number on to it and put it in the phone. Off you go. That simple.

When you bought your Vibrant, check in the box, there should be 2 sim cards.
i just called t mobile today and they said that my sim card is old which is weird. my sim card came with the phone 6 months ago. is there really a new sim card?
So they said i do need to change my sim card, will my number be changed?

If he upgraded to the vibrant and the rep happened to leave the sim in there then there would be another one. There is typically only one sim per box.Usually if you are an existing customer and you upgrade the rep will take the sim out of the box and keep it.

Nope. Number will stay the same. They just activate the new card with your number and deactivate the old. Yes, they came out with a new version of the sim card a while ago.

oh ok thanks. i really forgot to ask why did they put this sim if it's not compatible with the phone. I didn't know that they have a newer sim card.
thanks!

Well the one that you have should work fine. But like anything else they occasionally go bad. They updated the sims when they started upgrading the network. Just gives a better connection on 3g/4g.

Hello everyone,
Last night we updated an s2 to the original ics, using the ota.all went well during the presidure, but later we found out that it can't receive calls, or make any calls, and it cannot register to the network.The Sim is greek, and the phone was never flashed with room in the past, everything was original from Samsung.
Amy ideas?
But it does ask for pin code and reads the sim card?
Sent from my GT-I9100 using xda app-developers app
No pin, doesn't ask for it.nor locs the screen.
I looked in apn and there is nothing there.
So it doesn't recognize sim card?
Sent from my GT-I9100 using xda app-developers app
I guess not.
But we have replaced it with a brand new card,same number and network.
And is the new card working?
Sent from my GT-I9100 using xda app-developers app
Have you tried to input a new APN? You can get the specific APN for your carrier with an internet search or a phone call to your carrier.
The new is not working either.i tried the apns ,i have the same carrier.But it is not able to save them.
The phone is working fine when i put my own sim in it.
Go to about phone and see if your imei is empty. If it is empty then your efs got corrupt and I guess ypu don't have backup of it. If you do have a backup then restore it. Otherwise I hope you still have warranty left as your going to need it.
Sent from my GT-I9100 using xda app-developers app
Imei is there,checked it with both cards
So, after searching alot,i have found out, that if i disable pin it all works fine.But the screen doesn't lock, and i can't use pin.As soon as i enable pin again then no more calls.
Any ideas?
Search for keystr.

What do you mean by that?
Still haven't found a way around it.The phone doesn't register in cell network when the pin is enabled and lock screen, or pattern do not work no matter what i do.
How about new modem?

So I've been reading on these forums that some roms don't have gsm working. Can someone explain what gsm is and what it does? Sorry for noob question.

gsm = signal
without it there is no calls or texts
Or in other words, no calls or texting.
Ok thanks guys.

"Global System for Mobile Communications"
This technology uses a small SIM card to contain the mobile phone details such as your phone number & etc. This allows one to swap the SIM card into another phone and have it simply work. The SIM card can also store a limited number of phone numbers. The technology is used everywhere in the world, but only on AT&T and T-Mobile in America.

Not sure to understand since I'm not in those carrier and I can swap my SIM card into any other phone and it will still work. I'm in Canada and this works for any carrier for all I know. The SIM also contains phone numbers and can hold a bunch of SMS.

Because you are in Canada or bought an unlocked phone.

I forgot about the SMS storage. Your SIM card can be put into any other GSM phone. It could not be put into a Verizon phone, for example.
Hi there guys, i have quite a peculiar problem and i tried searching the threads but to no avail.
I have an international RAZR XT910, i got it used, and as far as I know, it is sim unlocked, because i am already using a local sim on it (i live in the Philippines btw) and no local carrier offers this phone, thus the assumption that it is already sim unlocked.
However earlier today, when i tried to pop in another local carrier's sim card, i cant get any signal, and i dont even get the "sim card invalid" screen, just won't get signal at all.
I know the sim card is good since i tried using 2 different ones, but both wont get a signal.
When i put back my original sim card the phone works normal and gets signal.
My question really is, how do i make sure the phone is unlocked? Coz i know with samsungs there are codes you can use.
I have stock ics on system 1 and PA3.8 on system 2 using BMM btw, if that matters.
Hope to get a response. Thanks guys.

How old is that second sim card?
I've had that problem when I bought this phone,my sim was10 years old,it was functional in some older phones but not in this one,because of old chip,so I had to replace it with new one.

That's what i thought, so i bought a new one, (hence 2 SIMs) still same issue, no signal.
I'm thinking, is it possible that phone may not be completely unlocked?

Never heard of it, my thoughts were same as welder73s... Any chance to try SIM from yet another carrier? =)

I just did, we have 3 carriers here in my country. I tried the other 2 and both have the same symptoms, no signal. :banghead:
I don't understand why this is fhe case, bexause i am sure that the carrier which works on the phone never released this phone, thus the phone being sim locked to this network is unlikely.
Isn't there a way to check the lock status of the phone?

Hello, I just bought samsung galaxy s3 and tryed to put in sim card, but it doesn't recognize it. I tryed to do factory reset lot of times but it doesn't helped it still writting no sim card. I tryed to put in my friends card who is in other network, so I think its not a sim slot problem. First think - it locked. Today I went to the salon of my operator and they sayed that my phone is not locked or black listed, so maybe somebody knows the solution for it ?
Really sorry for my english

Proble might be hardware: sim slot or sim card. Does your sim work on other phones? Do other sims work on your phone?
If its software, a fresh firmware flash with wipes should fix it.
I tryed to put sim to my brothers galaxy s2 and it worked, and we tryed to put other network sim to my phone and its too worked, but sim with the same carier like my didn't worked, if its a software can u give me link where I can find tutorial how to fix it ?

I've known some weird bug to happen (1 in a million or more) where a specific sim won't work on a specific phone, a friend working for movistar had that happen. Don't know why, just that sim won't work in that phone. They had to make a duplicate of the sim with a different format.
Check with your carrier to see if a different sim might work. And make sure its not a problem with the phone being locked.
Can you tell us. Is the phone 2nd hand or brand new?
I was thinking that if it is 2nd hand, maybe the previous owner flashed Custom Roms and may have damaged the 'EFS partition' when they flashed Stock firmware back onto the device before selling to you.
No, if EFS is damaged then device wouldn't log into any network.
Try to repair your device with Kies if you don't know how to use Odin:
http://forum.xda-developers.com/showthread.php?t=2088809
If it doesn't help visit your carriers store and get your SIM changed.
I tryed to put in maybe 4 cards with the same carrier and it didn't worked, yes phone is for 2nd hands :/

Now, when you say it doesn't recognize the sim cards, do you get a "sim not inserted" message?
Or does it recognize the sim but won't allow making calls or connecting to mobile data?
You say with different carrier (your friends sim card) it works. But with your sim card and others from the same carrier it doesn't work. That sounds just like a network locked phone.

When I turning it on it loading about minute and in that place where is network bars is pic like phone blocked I think, but after loading it shows me a perfect connection, but in my task bar writting "No SIM" and under it with lower letter "Insert SIM card". On the lock screen is too writting "No SIM card - Emergency calls only"
I know that it's sounds like network locked, but I was gone to the salon operator and they sayed me that phone is not locked, but I did not understand, or only to their network, or general. Where can check it ?

This totally looks like a sim locked phone.
What you already know is that the phone works with your brother's sim card, so the phone works with your brother's carrier. You know it doesn't work with your sim card or any other sim card of your carrier.
But you are still not sure if it is a simlock.
Just check with a sim card from another different carrier (one that is not your carrier, nor your brother's carrier). If the phone is simlocked it shouldn't work with that 3rd carrier.
