Hello ShamsMalik,
Welcome to the community!
Thank you for providing that information for the community! With regards to the Redmi Note 10 Pro, these appear to be the specifications:
4G: LTE FDD B1/2/3/4/5/7/8/20/28/32
4G: LTE TDD B38/40/41(2535-2655MHz)
3G: WCDMA B1/2/4/5/8
2G: GSM 850 900 1800 1900 MHz
See also Redmi Note 10 and Redmi Note 10s.
According to those specifications, those devices would have the compatible band/frequency for 2G (if and where available) and '3G' networks. With regards to LTE, those devices would have a few compatible bands/frequencies. You can verify the compatible bands/frequencies here.
While the devices should work on the networks, coverage would depend, in part, on corresponding bands/frequencies used at your surrounding cellular towers. You can get an idea of your area towers here. In addition, it should also be noted that the different bands/frequencies vary in their characteristics with the lower frequencies being able to travel farther and better penetrate objects (see graphic here). Those phones do not appear to have a compatible 700MHz band.
In addition, you should note certain features (ie Wifi-calling and voLTE) are only available with supported devices (see here). Since Xiaomi devices are not offered by Fido, it's unlikely those features will work.
Hope this helps 😀
Cheers

Hello Alfred1,
Welcome to the community!
Judging by those specifications (and those listed on the Xiaomi website and here), that phone would have all of the compatible bands/frequencies for the 2G and '3G' networks. With regards to LTE, that phone would only have one of the compatible bands/frequencies, band 7 or 2600MHz. You can verify the compatible bands/frequencies here. While the phone should work on the LTE network, coverage would depend on corresponding bands/frequencies on your surrounding cellular towers as not all cellular towers use all of the bands/frequencies. You can get an idea of your surrounding cellular towers here.
Hope this helps

Hello again,
That's not an easy question to answer. Ideally, a phone would be fully compatible with all of the compatible bands/frequencies. That said, you do not need to have all of the compatible bands/frequencies to work on the networks.
With regards to 2G and '3G', I would personally try to have all of the compatible bands/frequencies. With the exception of voice-over-LTE (voLTE), voice calls are strictly limited to those networks. (You should note that as it stands, certain features such as voLTE and Wifi-calling will not work on non-Fido unlocked devices.) Text messages (SMS and MMS) also use those networks. My previous phone only had one of the compatible bands/frequencies for those networks. For the most part it worked, but I do remember having to drive across town in order to be able to download a MMS...
With regards to LTE, I would again try to have all of the compatible bands/frequencies. While a phone with limited compatibility should work on the networks, the different bands/frequencies have slightly different characteristics. The higher frequencies (ie band 7 or 2600MHz) generally have a larger bandwidth (see table here), meaning that they potentially offer greater data speeds. I said potentially, because there are still a number of other factors that affect data speeds -- signal strength, network congestion, etc.
On the other hand, the lower frequencies have the greater travel distance and penetrability (see infographic here). So bands 12 or 17 (700MHz) might be a better option if you live further away from cellular towers or in cities with a large number of buildings (obstruction interference).
In addition, as noted above, not all bands/frequencies are used at all of the cellular towers. Generally, band 4 (1700/2100MHz) tends to be more widely available at the cellular towers since it was the original backbone of the LTE network.
Sorry I couldn't give a more definitive answer to your question, but I hope this helps
Cheers
