New to ATT and GSM

[jerhomey]

Hello,

I have been a long time Verizon user and our company recently switched to AT&T. I would like to know if I can use a T mobile phone on ATT ? particularly a lumia 435 ? Also can I use other phones that are outside the USA as long as they have the correct bands ?

Thanks

As long as the phone is SIM unlocked and supports the correct bands it will work. The Lumia 435 might be locked to T-Mobile but can be unlocked. Keep in mind the phone does not support LTE at all so data will be slower. Many phones from other countries are unlocked but some do not support or fully support US bands.
