Problem with Antenna?

I have a problem and think it is related to the antenna my Galaxy Pocket. My phone detects only 2G networks with strong signals. In the 3G signal is always around-85dBm 10 asu 113dBm 9asu Until then it goes back to 2G when 3G is on varies the signal level and is impossible to use mobile internet or make calls. Network modes that appear to me are HSDPA (which works very badly), EDGE and GPRS, tested with all operators in my country (Vivo, Claro, TIM and Hi). All with the same results in terms of signal. Already updated the stock ROM, installed customs and nothing resolved. I have a Defy Mini XT320 signal and this unit is very good the internet is fast. What do I do?
