Xiaomi Mi 4i BYOD?
Answered

After doing a lot of research I'm basically in love with this phone. It's everything I want at an amazing price point. I'm having way too much trouble discerning what connectivity I can get in the US though. I don't understand if the differences between CDMA and WCDMA/SPCDMA or between HSPA and HSPA+ or HSPDA. Anyways I was hoping someone here could tell me what connection I can or can't get if I buy this phone. The manufacturer lists it's networks as:

4G FDD-LTE/TD-LTE bands 3, 7, 38, 39, 40, 41
3G TD-SCDMA 1900mhz, 2000mhz, WCDMA 850/900/1900/2100mhz
2G GSM 850/900/1800/1900mhz.

The 3g bands are mainly where I get confused. 2100mhz is listed on the ting GSM faq but I don't know if WCDMA 2100mhz is different from HSPA/HSPA+ also I don't know if the chart in the GSM FAQ only applies to GSM phones and maybe this phone supports CDMA bands? It's just overwhelming and I can't make heads or tails of it. I miss the whitelist. The compatibility checker is very convenient if you actually have a phone in your hands, but if you're looking for a phone to buy/bring to ting it's not much help.

Thanks in advance for any help you guys can offer. P.S. if this phone can be brought to ting, check it out. Pretty fantastic handset.

  • The phone cannot work on Ting CDMA (Sprint). The device does not have the needed radio capabilities.

    It may have some limited functionality on Ting GSM (T-Mobile) if the phone is unlocked. I know LTE will not work. It may have 3G data, depending on the network in your area.

    Compare the phone's specs with https://help.ting.com/hc/en-us/articles/205428938-Can-I-Bring-My-GSM-Device-to-Ting-Compatibility-and-Unlocking-Guide

    I'm willing to live with just 3g, I just can't tell if I'll have it. The phone supports WCDMA 2100mhz. Ting supports UMTS/HSPA/HSPA+ 2100mhz (AWS). Is 2100mhz = 2100mhz? or are different signal types both transmitted on this frequency? Also is there any way I could find coverage maps specific to that bandwidth?

  • I am not sure if that information is shown on Ting's coverage map.
    To be sure, you should be able to call or chat with Ting support.
