Pretty sure only SIM slot 1 supports 4G, slot 2 is 3G. I didn't buy it for the dual SIM stuff so I have only tested the first SIM slot and have had no problems with 4G.
As for 4G+, that is just a branding thing. 4G+ is 4G. there is no difference. The only reason that some phones put 4G+ on their status bar is just that they modified the icons in the ROM.
see - https://en.wikipedia.org/wiki/4G
If the phone says 4G, you are gettign 4G. The important quote on that page is:
Confusion has been caused by some mobile carriers who have launched products advertised as 4G but which according to some sources are pre-4G versions, commonly referred to as '3.9G', which do not follow the ITU-R defined principles for 4G standards, but today can be called 4G according to ITU-R. Vodafone NL for example, advertised LTE as '4G', while advertising now LTE Advanced as their '4G+' service which actually is (True) 4G. A common argument for branding 3.9G systems as new-generation is that they use different frequency bands from 3G technologies ; that they are based on a new radio-interface paradigm ; and that the standards are not backwards compatible with 3G, whilst some of the standards are forwards compatible with IMT-2000 compliant versions of the same standards.

4G+ is just true 4G. So if the Mi 5S Plus says 4G, you are getting 4G (or 4G+ as they are identical).
You can verify this with any LTE bandwidth monitor apps (such as signal spy) which will tell you that you are on LTE and which band you are on and you will know then that you are on 4G.

Hi mates. I'm living in Netherlands ...have problem with 4g..
My phone doesn't support band 20 ( 800 mhz )..
Is there an option to access 4g?...
Maybe flashing a custom ROM ?...

offhand, I do not know of any non-root tools for getting any information about what network you are on.
My next best bet would be to get some bandwidth testing tool (speedtest for example) and then check what speeds you are getting out of 4G and compare that with what your provider claims you should be getting. My provider gives me 750 Mbit/s as a peak speed, and 250 Mbit/s average. If your speeds are close to that, then that is all that really matters. If it indicates 4G or 4G+ or 4G LTE or whatever indicator it says in the top, if your speeds are slower than what you are paying for, you will want to look at rooting and opening up some of the 4G channels which will likely give you better speeds.
If you still have your old phone, do a speed comparison in speedtest (or equivalent) and see if it is faster or slower on the new phone. If it is marginally slower (or faster) that can likely be ignored. If they are drastically different, then I'd look at rooting and unlocking other channels.

If you need to access 4G and your operator only supports band 20, then your only option is to use a different phone. From everything I've read on this forum, the hardware has been modified to not support band 20 due to licensing concerns. So a custom ROM or custom Kernel will not affect being able to use band 20. There is no way around it at this time that I am aware of.
Now, if your provider uses a band other than band 20 (or uses 20 and another band), then you can open up the other bands. There are several posts about doing that.

it is really easy

4G : 150MB/s max
4G+ : (phone connected to two 4G frequencies) 300MB/s max
4G++ : (three 4G frequencies) 600MB/s max

Xiaomi MI 5s is supposed to support up to three 4G frequencies at the same time BUT, in a lot of case, like here, in france, band 3 (1800Mhz) and band 7 (2600Mhz) are the two compatible 4G freq, BUT Mi5S Plus can't connect to 2 freq simultaneously and we don't really know the reason, in china it's not FDD LTE but TDD lte and it works, maybe it just doesn't work on FDD...
This is what we are asking to dev, find a way to enable dual or triple 4G freq in FDD LTE to acces high speed 4G.
I'm sure it's somthing to do with modem or kernel modification :S

Best regards

At the risk of starting a flame war, could you cite your sources on that?

I believe the speeds you quoted are wrong. Telus up here in Canada operates on 4G LTE version 8 which supports up to 750 Mbps max, but to expect average speeds around 200 Mbps (http://www.telus.com/en/sk/mobility/network/). NOTE - 750 Mbps is 93 MB/s approximately. Mind you, independant studies show that average speeds are closer to 20 Mbps for telus ().

Now, correcting my previous post - I was incorrect about our phones supporting 4G+. I misinterpreted the wikipedia article.
Looking at GSM Arena for our phone, it only supports LTE and thus not 4G+ (http://www.gsmarena.com/xiaomi_mi_5s_plus-8350.php). If you look up the galaxy S8+ for example, it supports LTE-A which would be 4G+.
We can read about LTE-A here - https://en.wikipedia.org/wiki/LTE_Advanced
and you can see which speeds different carriers offer here - https://en.wikipedia.org/wiki/List_of_LTE_networks

For example, Telus, which I am on, only recently added support for category 11 - 600 Mbps.

The 4G++ that you speak of I believe is LTE-A Pro (https://en.wikipedia.org/wiki/LTE_Advanced_Pro). But they are not referring to it as 4G++ but as 4.5G or 4.5G Pro.

Looking at this article - https://en.wikipedia.org/wiki/List_of_devices_with_LTE_Advanced#Xiaomi - it appears that our phones do not support 4G LTE-A. What is a little confusing is that the 5s does support LTE-A.
I could be mistaken, but I am pretty sure it is a hardware restriction to not support LTE-A.

After some search, Mi5S Plus is only 4G+ intraband and not with interband 4G+

I sold mi5s plus and buy redmi 5 plus better
I don't say mi 5s plus used for 4g or4gplus
