[Q] HKG 9505 work on T-Mobile 1700MHz LTE?

I'm traveling to USA soon and want to buy a data prepaid SIM. Will my Hong Kong S4 (LTE version) work on T-mobile's 1700MHz LTE network? If not, what hazards should I look out for when choosing a prepaid SIM while in USA? (Preferably with voice call and 1GB data for 2 weeks span)
Thanks.

[Q] 910c weak signal

I just got a 910c international unlocked and bought a prepaid t-mobile sim card while staying in USA. I'm getting a very weak signal compared to other phones. Phone broke?

Help needed. Can we convert CDMA to GSM?

Hi, I recently bought a Samsung S5 from US. It is a tracfone company phone with straighttalk. It has a tracfone CDMA/LTE sim card in it and I haven't purchased any prepaid plan from straighttalk yet so I can't activate it. I live in India and in order to get it unlocked here, it has to be converted from CDMA to GSM. Is there anyway I can get my phone working? Any help will be appreciated.

Dual Sim LTE/3G

Hello. Do you know if the dual sim version supports 4G LTE on one sim and 3G on the other? Unlike the S7 which supports 4G on one sim but the second sim needs to be on 2G.
Thanks

LTE on one and 3G on the other. My S8 was bought in Dubai.
