and you're sure it support 3g on the frequencies used by your network provider ?

An other reason which appears in my diamond : he doesn't show the 3G logo until i'm connecting to data. (For example i have EDGE logo, and after he shows H logo...)

it depends on what you consider 4g? are you talking about LTE or are you talking about HSDPA/HSPAP? if its LTE it should show up as LTE, but depending on where your located and which HTC one you bought you might not have the bands. if your company has HSDPA the H that shows is normal. H for our phones(atleast on the international version) is a combo of HSDPA and HSPAP which in tmobile USA's eyes is 4g and 4g+. even though technically its 3.5g and 3.5g+. so need a bit more info on your end to get an idea of what SHOULD be happening.
phone model? international? ATT? tmobile? heck sprint?
provider?
maybe country? it seems like your in another country i think?
and if your in the USA then maybe city you live in? cause LTE on tmobile has only rolled out in like 10 cities though ATT has better signal

i live in Hong Kong and LTE support 1800/2600 band, i dont remember the exactly timeline , i just remember when i flashed ARHD , the 4G is still working
but bad reception, so i flashed another few rom until i notice my phone can not get the signal at boot. Thankfully, jaythenut tech me a method to solve the signal problem, but it cannot get the LTE now....very very strange

*#*#4636#*#* paste this in the dialer
Choose the first option in the list that comes up, and see what "preferred network" is set to. If it doesn't say something about "LTE" theres something wrong.

I have a problem with the signal of my S3 Mini, actually only in my house I think, I mean only in a same place all time. The signal icon show 3 o 4 lines of signal but if I try to call or send a message, didn't work. Just don't call and dont send message. I try to change the firmware with another modem, flash the latest modem, but the problem don't solve. I've got the i8190L with a unbranded firmware, no custom rom.
Anyone know how can I fix this problem? Thank and sorry for my inglish.

Well, thanks you for your reply but befor an exahustive research I find the solution, or apparently solution. Just change the Auto GSM/WCDMA to Only WCDMA and the signal comes to my phone and now I can call and send messages.

Yes, This have nothing to do with rom or modem. It's an issue about the signal strenght. Concrete walls?

WCDMA basically reffers to 3g
are you confirmed that the 3g service that you wanna use works in your area
you should confirm this by asking about this to the network provider through customer care
if that 3g service is not available in your area then you cant get signals in WCDMA mode

So you are using WIFI, have you contracted a data rate on your mobile?

Where do you live? There might be some issues with different WCDMA signals in countries

As long as it is the firmware for the model (S5830 firmware->S5830, nothing else), there should be no problems.

Strange switchs 4G (LTE) to H+

Hi,
I'm new in MI8 community ? (just living leeco lepro3 ). I've strange switchs between 4G to H+.
I explain ?. Previously, at home, I was all the time in 4G with my PRO3. But now, my MI8 switchs time to time and during the switch I loss the connection. Nevertheless, my device receives full signal in 4G and it stays connected on the same BTS.
If I set it in plane mode ON and after OFF...back to 4G for a short time...
I'm on miui10 and on Sosh (orange) french network.
Tks for your help

Hey !
I'm also french and i'm experiencing that kind of H+ switches, as you I had 4g in these areas before with my oneplus 3 with Bouygues Telecom ISP and now i can't even connect to the internet, must be the antennas...

I can connect to 4G but something doesn't work fine...I can't stay connected. The level of the signal increase and dicrease strangly.
I'm a little bit disapointed :crying:

Because each phone have different bands and if your phone doesn't have the right band for your area cell tower then it'll keep changing back to the most stable connection it can do.

Sure, I know that. But I leave in campaigne with only one BTS. So I'm always connected to the same antenna.
And if it was an issue with the frequency band (lepro3 has the same), switching OFF/ON, airplane mode should not fix my issue.
I've tested with Mate 20, and i'm always 4G in full power received !

Nobody else has the same issue ??

I have the same issue, 4g and H+ are switching all the time. Sometimes it keeps switching several times in a minute on a fixed location.
I am in Croatia, operator is A1, Mi8 Global model.

very well it seems like it's not an isolated bug. can we trace this kind of problem to xiaomi and if so by which channel?

Hi, i'm still facing time to time the issue. No fix planned? I'm not alone.

Zero promises here but you can try forcing the network mode to LTE/UMTS auto (PRL) and check if it makes a difference.
To Change 2G to 3G 4G LTE only network mode in Android Phone via USSD code, take the following steps:
Dial *#*#4636#*#* OR ##626* OR ##786# in your phone
Select Phone Information
If you have Dual SIM Select the Slot (SIM) you want change settings for
Scroll Down and select the Option Under “Set preferred network type”
Click to expand...
Click to collapse
Also works by pressing 5 x times on settings \ my device \ total storage

Thks but It's not a good solution. I won't force network type choice.

If you flash 9.1.17 Xiaomi.EU they have updated Network Switching handover to European UMTS, instead of default chinese TD-CMDA to WCDMA as Stoffl_ says.
I had the same problem as you say of switching from LTE to H+ because of this. Either change it manually after boot or unlock the bootloader and flash another rom. Until they fix it in global, if they do.

So, after few month my feedback. I've try to force the switching of prefered type of network and it does not work. So I expected a new version of MIUI who can fix it...
Today, I'm in the lastest Miui 10.3.3.0 stable and the issue still
