Default [Q] Miui v5 network problem

Hello! I installed MIUI v5 on my HTC ONE S and it looks like my network does not work. My data is enabled but still it does not work. I tried to flash the rom again and turn the network data again but still is not working. When I swich to MIUI v4 the data is working. I don't know what could be the problem? Help please!!
P.s. I am using T mobile and my phone is S ON
