Hi
I have a really weird problem: i have brand new Oneplus One with CM11s , my mobile gets 3g signal more or less but it cannot find the 2g signal .In my area there is full 2g reception.I flashed many roms,modem firmwares,unblocked the bands supported but nı success.I played around nv items on qpst and i got the 2g signal then 3g and data was gone.I am sure my problem is related with nv items yet i dont know how to do it.I will be very greatful if you can help me.Thanks in advance.
Hi all!
Im using a moto E with Tata Docomo sim.
The problem is that when I change my network mode to WCDMA only, the phone shows only 3G and not H+. However, when I go out of my home, I get H+ with full signal.
I've talked to customer care and the issue is that another cell tower which doesnt support HSPA is stronger in my home so the phone connects to it and only shows 3G even when data transfer takes place. 3G is so much slower than HSPA/HSPAP.
Is there any way I can force my phone to connect to HSPA/HSDPA only?? I dont mind if the signal drops a little. Since it is possible to force the phone to using 3G only, I thought forcing to 3.5G could also be done
Also my phone is rooted so changing any system file is not a problem.
Please help..
Thank you.
When I manually switch between 3g and 2g it drops the signal completely. When i go from lte to 3g it doesn't drop the connection or give me any errors.
This drop is enough that when I'm in a building i almost always have to have 2g forced. If i have 3g and someone calls i usually drop to 2g, but doing so causes the call to drop instead of handing it off.
I've tried to google it and I've seen this a few other times but I've never seen a clear reason why? Does anyone experience this or know a solution? It's done it on different phones over the last few years. All android too.
Someone must know something. I'm on t mobile in central Florida if that helps
I'm on MIUI dev. At my place the Jio service is pretty poor. I get the max. speed of 100KBps throughout the day, and only during the nights I am able to reach upto 3or4MBps.
But, what I've seen is that sometimes in between, my cell connects to some other Cell Tower (Jio's only). I can tell you this because the network strength is always full at my place but when it gets switched to the other Tower's signal, the strength is around 40-50%. And, suddenly the speed gets boosted upto 2MBps from 100KBps, for the brief 10secs. Then again the network strength goes full and the speed comes back to its normal.
So, what I think, is that there's another cell tower which is farther then this one but has less no. of users and hence better speeds.
So, is there anyway that I can switch to that network permanently. I've read about setting the phone's modem to a particular freq..
So, guys tell me what I can do.
TL; DR How can I use the other cell tower of my network which has better internet speeds but has weaker network strength.

Tested it. Works as it says, but the speed is still same. Hell, Im getting speed around 100kbps+ on Band 5, while on Band40 the speed is around 60kbps. Although the network strength is full in both bands.
Anyway, thanks for your reply. It must be problem with Jio services only.
Poco F1 (MIUI Global Stable V11.0.8.0.QEJMIXM ROM) has significantly better 4G signal strength than 3G or 2G. In fact I got problem with that, when I'll recieve call or make a call, the phone automatically from 4G goes to 3G or 2G, and in that moment signal strength bars goes from 5 bars (4G) to 1-2 bars (3G) and often other side cannot hear my voice. Later I choose manualy network (3G or 2G) and when I try yo make a call => "Cellular network not available"
What should be the problem? Is it software or hardware problem? ...btw I make a clean install/flash thru fastbot of MIUI Stable V11.0.8.0.QEJMIXM few days ago, but I cannot notice some differences

It means that VoLTE (Voice over LTE) is not enabled or it is not available in your region. That is why it is switching to 3g network to make a call. As for the signal bars, never trust miui on that. Got to about phone -> and find a option where it shows imei, sim status, etc.

Yes, in my country VoLTE is not available, but I don't see that as an insufficiency, I use it only for data/internet 4G.
MIUI signal bars should "work" same for both 4G and 3G/2G, i think it is some other problem. Btw use it code *#*#4636#*#* (testing mode) and there i can manually set my network (WCDMA only, GSM only, LTE only, CDMA, TD-SCDMA/UMTS... and all variations of them). Usually LTE strength signal is "70-80dbm / 50-60asu". When I set to WCDMA only or GSM only it is ""100-110dbm / 1-10asu" and that's in the middle of the city (where I live). When I enter some Mall, stairs of building or hike on local mountains, when I want to make a call, the result is "CELLULAR NETWORK NOT AVAILABLE " :crying:
Does it can be antenna problem? But then, why 4G signal is far better than 3G? Does it have separate antennas??? I got no idea really what should be the problem about that

Without VoLTE you cannot make a call on 4G network. The SIM will automatically switch to 3G/2G. It's the same across all phones, all carriers, and in any country.

It is OK that. I know that. In fact, I GOT PROBLEM WITH 3G AND 2G SIGNAL STRENGTH. I mention 4G just to compare signals. I got 5 bars on 4G and 1-2 bars on 3G/2G on the same location. I have super fast internet thru 4G (50-100mbps), while when I set manually to 3G it didn't even connect data, furthermore, I cannot make a call (Cellular network not available). Obviously it is a strange problem. I'm not arguing about VoLTE or 4G...
Is it the same antenna for 2G, 3G and 4G signal? Should I replace it? I will repeat myself again, I can't get HOW CAN 4G signal be better than 3G/2G?!
I insert both SIM cards (with POCO F1 I use dual sim cards) to other phones (Xiaomi Mi4c, Alcatel Pixi 4, Lenovo A536...) and everything is OK with all of them. So, that means it is a POCO F1 problem.

Try changing slots. Or try a different carrier. The culprit could be your network provider. If the problem still persists go to any service center and get it checked. BTW it is actually strange to see that 3g/2g network is weaker than 4g. Usually it is the other way around.
