HSPA Only
1) When i select any of the above option except "GSM only" its showing me weak network signal only 2 to 3 point instead of 5 and its keep on changing frequently not stable and its shows 4G sign but internet speed is good but weak signal because 4g Won't support in india
2) when i select "GSM only" then its show full signal and its work fine but its show 'e' sign means 2g speed very slow internet speed
3) So i talk with Idea Operator they told you select WCDMA Option but that option is not available so how to bring that option in network mode
so please help me to solve this signal problem with 3g running right now weak signal with 4g
Thanks in advance

Hi
Your observation is true..I have Skyrocket,but the ATT Version,using with BSNL..
My network mode is not exactly the same...so..I have 'WCDMA Preferred'..and using it I get 4G(HSPA)..but with 1 or 2 signal bar at my home...but at some places I get good signal(4G is not avaialbale everywhere).Since I'm not a internet freak,i switched over to 'GSM Only'.in which I get at least 4bars..with good internet connectivity('Edge'!)
India is not truly a 3G place,leave alone 4G..Mind you this is the situation at 'India's so called silion valley'--Bangalore:highfive:
If the Rogers one don't have this,may be FLASH a ATT ROM---I use

Network with 3G connectivity

Hello guys, i am from India. Here, I have activated airtel 3g and i am from Maharashtra state. Here, airtel network uses IDEA network for 3g packs as they don't own the spectrum. I kept my cell in 3g mode and "automatically select network", but it stays in 2g(Same doesnt happen in my note 2, using 3g in auto mode). If i manually select IDEA from the list of networks, it goes to 3g. I want to keep it on auto, like switch to 2g when 3g is not available. Settings are same. How to make it switch to 3g automatically. Preferred mode is 3g. Any problem in my handset?
Thanks

No 4G / LTE in Austria?

I'm customer of the local carrier "Drei" (Hutchison) but my Pixel (bought in Germany) does not connect to the 4G / LTE network.
The support of Drei is not able to help me. LTE is working fine with the same SIM on the OnePlus One.
Any clue how to fix that?

There is regional problem I came across. In India here we dont have VOLTE support on pixel

What LTE bands do they use on Drei?

Same happen to me in Portugal with MEO. I can't seem to solve it. Talked with my carrier support, they don't know why I don't have 4G/LTE.
I never got 4G, but my SIMCard has no issues with iPhone getting 4G right away.
Is it Pixel issue? I start to think it is..

3/Drei is listed here: https://en.wikipedia.org/wiki/List_of_LTE_networks_in_Europe#Commercial_deployments
The specs of the Pixel are listed here: https://madeby.google.com/phone/specs/
That is all information I have got.
Is there any possibility to display information about nearby LTE senders via an app?

After activating "LTE only" via *#*#4636#*#* it works. Everytime I search for networks or reboot my phone it still connects via 3G and switches back to "LTE UMTS auto (PRL)".
Seems to be a software issue.

I use the phone on Verizon and don't have any problems connecting to LTE using any available mode (Global, LTE/CDMA or LTE/GSM/UMTS). However, if I set the mode to LTE-only via the menu, it will also reset when I either reboot the phone or if I just open the "Cellular networks" menu. I think it's how it supposed to work because that menu doesn't have the LTE-only option, so it resets the mode to whatever you see there. The solution is simple - if you reboot the phone change the mode again and don't go to the "Cellular networks" menu
Regarding why it doesn't work with "LTE UMTS auto (PRL)", it might be because Drei didn't configure a handover from UMTS to LTE on the cell site you're connected to. It looks like Pixel finds UMTS signal first, but doesn't know that LTE signal exists due to a missing handover. Another phone might be fine if it searches for LTE signal first. But if you can see another phone switching from UMTS to LTE in the same spot, my theory is wrong.

2G issues (turn off 2g)

Hi,
is there any chance I can turn off 2g on a Samsung s6?
I am having conenction issues when the phone is connected to a 2g network. The conversation is not being established - rather than hearing someone I hear terrible humming noise. Telekom Germany confirmed with there call log, that everytime I am using 2G there is an error. I checked with a few SIM cards (issues with all tested Telekom SIM, O2 SIM cards in 2G work just fine- which is really odd)
When I am in a LTE network the calls are perfect. When I then manaually change to 2G the noise starts again. So there is no problem in a 3G or LTE network e.g. in large cities. In the countryside calling i snot possible. I would rather use a bad 3G connection or not call at all than usind 2G. Is there a hidden menue where I can disable 2G? In the regular menue it only works the opposite way (turn off 3G, LTE).
thanks

You can't disable 2G and use auto 3G/LTE.
But you can use only 3G, or use only LTE (you can't recieve calls if your operator & SIM doesn't support VoLTE).

How to enable automatic GSM fallback?

Hi,
On my old Sony, I had something like "LTE/WCDMA/GSM" mode, so phone could successfully fall back to GSM when 3g/4g connection is weak.
Is there such an option for Pixel 3?
I've tried various settings from 4636 menu, but it looks like there is no such option. Even in "GSM auto (PRL)" or "Global auto" is still uses UMTS with -100...-110 dbm signal strength, while in "GSM only" there is -89dbm available.
Is there a settings or some adjustable through adb option, which allows GSM fallback?
I also could write an android app, in order to switch into GSM in some circumstances, if possible.
I've located in the eastern europe, if that matters, and LTE/WCDMA work best on my network, except in my office location.
