Help needed - Evo 3D Gsm 3g network

---

Hi everybody

I recently retired my old Xperia X1 and bought a Htc EVO 3D Gsm.

The cellphone is Canadian Rogers version. and also its unlocked (sim free)

I live in Brazil, I can make calls normally but the 3g network don´t work at all.

This cellphone is quadriband correct ? so its suppose to work with any carrier right ?

Any ideas ? Please help

If need more info just let me know


Just in case, I use TIM as carrier and the 3g frequency here is 2100mhz so I discard band problem


Tks =)

Ok, I think I found the problem

There´s no APN settings

But.. i enter manually the settings for my carrier. It appears "saved" but the settings still blank

Any advices?
