Data connection problem. Hardware or software problem? - Galaxy S III Q&A, Help & Troubleshooting

Hi, I bought this smartphone, but the data connection never worked.
APN is OK, I tested my simcard in another phone, and its OK.
He connect with the provider, has an IP, but not received pkts, just send pkts, so, he don't open/download anything.
I test another roms, cm9, cm10, and alot of others. I tried to change the modem, but without sucess.
When I put the code: *#*#4636#*#*, I can see:
Data attempts: 0
Data sucesses: 0
PPP send: 1736pkts, 127559bytes
PPP received: 0pkts, 0 bytes ( sometimes 1pkts)
So I just send, but not receive packets?
Thanks for you help.:good:

Yes, It's a new phone.
Model i9300.
IMEI is the same.
FW: IMM76D.i9300UBBLG2.
I tried another roms,kernels etc, but no sucess.
So I returned to the oficial one, because I have no idea whats happening, and if I no discover, I'll take it to the warranty.
Thanks.

what you can do is try a hard reset of your phone , then flash the stock Rom.

I already tried that, without sucess.
First, I guessed the problem is the simcard, because phone is new.
But I put the sim in another cellphone, and internet works fine.
Then, I bought another simcard from other provider, and internet worked in another cellphone, but in i9300.. same problem.

That's right. Never had a successful connection, never.
wifi works fine. I guess the only problem is about the data connection.
I can't understand how just this problem is there.
thanks for your interested.
