Force carrier band - Google Pixel 4a Questions & Answers

Is there a way to force carrier band on the 4a? Specifically for Tmobile/Sprint. Rooted OK if necessary.

Came here to look for the same thing.

That’s why I’m going with the 4a 5g so I can access 600mhz towers. I don’t believe you can access them in 4g

@xenokc You need root and an app like Network Signal Guru. We fought some issues on the Pixel 4's but have a new method for Android 11 that is simpler. It also works for the Pixel 3 and I expect it to work on the Pixel 4a. You are welcome to try, the instructions are here: https://forum.xda-developers.com/showpost.php?p=83499679&postcount=75 The app is in the Play Store.
@Jonathanlc2005 600mhz is the frequency that the network can operator on. T-Mobile uses 600mhz for LTE (Band 71) and 5G (n71). The Pixel 4a does support LTE Band 71. The Pixel 5 and 4a (5G) supports LTE B71 and 5G n71. http://band71.batcave.net/

Verizon Pixel Bands vs Google Store Pixel Bands

Are the bands on both the same or different. The Verizon Pixel XL seems to be lacking band 7, 12,17 26, 29, 30. Verizon has a habit of blocking essential bands so they don't work on LTE with other carriers in North America such as ATT and Tmobile. Can someone confirm? Thanks.

All VZW LTE phones are carrier unlocked. Most of these phones have bands to work on TMO and ATT. My son used a VZW Note 3 for a few years on TMO. The VZW Pixel should have all the same bands as the Google Store version. We'll find out in a few days but I'd bet you'll be fine.
Yes all of us know verizon phones are UNLOCKED. But they DONT have ALL THE BANDS that ATT and Tmobile use. The note 3 has band 4 and 13 and lacks band 17 and 12 so if you have ATT and tmobile where they use band 12 or 17 it will revert TO 3G SPEEDS. I use ATT And VZW . If I am buying the VZW model i want FULL FUNCTIONALITY OF ALL THE BANDS that the google store Pixel xl offers. NOT THE HALF ASSED with BANDS MISSING NOTE 3 or Samsung esque like versions.
google store pixel lte bands: FDD LTE: B 1/2/3/4/5/7/8/12/13/17/20/25/26/28/29/30 TDD LTE 41
VZW pixel LTE BANDS 2,3,4,5,7, 13, 20,28 Missing BANDS 1,8, 12, 17, 25,26,29 and 30.

Thanks for that but do you realize 3 years ago TMO didn't use band 12 in Chicago let alone anywhere because they didn't own the spectrum so that's a non issue. Around here TMO primary LTE band is still 4. Three years ago the VZW Note 3 worked perfectly w/ TMO, ATT I don't care about since I nver use them. The VZW Pixel will have all bands, to change that they need a different radio which isn't going to happen since Google is in charge of the software not to mention the hardware is the same for both, wait 3 days we'll see for sure.

Won't happen, I'd bet on it. They will be the same, VZW is known for lying a little.
They DONT need different chipsets or hardware for different bands. I am in the hardware industry. You can have the same chipset and lock different bands via different firmware. The qualcomm chips allow for that.
Can someone please confirm this? I am in the same boat as the OP. Want to use ATT Band 12/17 on the VZW model Pixel. I had to flash AT&T firmware onto my Verizon Galaxy S7 Edge in order to unlock these LTE bands. Hoping that since this is a more "vanilla" phone it may have the bands unlocked already.
I was wondering about this as well. I was going to just go to Verizon store and buy it since they have Pixel XL in stock but I am not sure if it has Band 12 for T-Mobile. Any information on this would help! Thanks guys!
Doesnt seem to be good news some guy on the pixel xl forum used att sim with the verizon pixel and only getting H+ speed. So lets see. Dont believe the PC mag article one bit. They said the boot loader was unlocked but turned out to be LOCKED.

4g+ problem

my oprator 4g+ work on band b3 & b7 but my phone just show 4g on statu bar but other phone like samsung show 4g+ on same area.my rom is 8.2.2 global stable.
is mi 5s plus suppport 4g+?
Maybe don't support
But I cannot call or receive calls only one SIM card work for call I use two operator
Irancell SIM card on slot 1 have internet and call other slot don't work internet and call then change sim card in slots HAMRAHawal can call in other slot irancell only have 4g internet and cannot call
When say problems with this phone in Miui forum manager banned me and don't help
I very very angry when saying problems and manager miui banned me why ?!!!!!!!!!!!!!!!!!!!!!!!
The xiaomi is cheating and cheaters the people of word and don't help the rubber is better than xiaomi
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 ?...
thanks
bmg002 thanks for your help.the app like signal spy does not work on my phone because of my phone is not rooted.do you know any app that i see network aggration without root?
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.

Everything you say is just false.
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
I say only my phone don't getting call
Or internet in sim1 by one operator change operator in sim1 to irancell operator only have internet cannot call or get call
The problem is from www.hamta.com must phone registered in this site in Iran for use
Hello dear u should unlock all lte band for using 4g+ in iran i tested this phone in uae and china have 4g+
How can I do it? I just installed Lineage 17 and only appear LTE. I am in Italy and with a brand new P40 Pro Huawei peak download is ~150 mbps but with mi5s plus this is the best can achive.
While Qualcom specs speak of 600mbps for the X12 modem inside the Snapdragon 821

Manual band selection on Pixel 4a 5G?

Is this possible? I know on the Samsung you can with QuickShortCutMaker but I can't seem to find the option on the 4a. If I set it to NR only I get no service. Basically I have 5G available but LTE seems to have a stronger signal therefore it locks on the LTE band nearly all the time. If I do happen to hit 5G it switches back after a while. I use this as a hotspot and it would be nice to have the 5G speeds when I use the hotspot as the LTE is not to great. I am not rooted (yet) but figured I'd ask the experts to see if this is possible.
This is a question for the Pixel 4a 5G so not sure why it was moved from the 4a 5G forum to the 4a forum...

Question OnePlus 9 5g ???

Does anyone have an idea on how I can get 5g on my op9 ,I pay for the service and I've tried a lot of settings fiddlin ,but nothing seems to connect .maybe I'm barking up the wrong tree all together ,lots of crossed facts online about this .Is it possible ?

This right here. As a former AT&T employee (corporate office, not retail level), I can tell you that it is most likely that the handset does not use the same 5G bands as AT&T.
AT&T primarily uses the n260 band (39GHz mmWave) and the Global OnePlus 9 does not use that band. In fact, none of the models of OnePlus 9 use n260. Now, from what I understand, AT&T *does* provide low-band n5 service in some areas so it IS possible that some users may report having 5G service on their OP9, but it's purely because they're in a low-band n5 area and as soon as they move into a more populated area where it switches to n260Go to and see,their phone will drop back to LTE.
What I can tell you from my real world experience is that 5G is really nothing to write home about. I live in one of the largest markets in the US and 5G is really not any faster than LTE most of the time. In some cases, it's actually SLOWER.

The LE2115 OnePlus 9 has AT&T's low band and C-Band 5G bands, with no mmWave, the LE2125 9 Pro has all of AT&T's 5G bands yet AT&T does not want to whitelist it for 5G access on their network. Verizon certified it for their 5G (OnePlus 9, nationwide 5G, and you can use QPST to enable C-Band on the 9, OnePlus 9 Pro, nationwide 5G, you can use QPST to enable C-Band on the 9 Pro, and mmWave), why can't AT&T?

Question International Version Availability and 5G Bands

I found the answer to this, so for others, the 5G bands are not the same on the international variant:

Hi All -
I've had a rooted phone for many years (currently a Pixel 5). I know US Samsung phones are not rootable.
Q1 - I'm looking for the international version of the Flip 4 but can't find it on AMZ, EBay, or anywhere else; is it not launched yet?
Q2- When it is, how can I check the available bands for compatibility with 5G T-Mobile (n41, n71, n260, n261)?
I know the US version has those bands but I'm not sure I want to go back to a locked ecosystem.
Vzw on my F926b experience.
Sim has to be in slot 2. Rooted to gain access to ServiceMode app (*#73#). Did some tricks that helped DSS control, MIMO 4x4 (4xALL), Prune (removed), and ignored CA Combination not matching. So far I've been able to get 4g+ (aka 4.5g) and 5g+ when isolating the lte to bands 2 or 66 (couldn't get it under band 4, 5, 13). That said, 5g band n5 kicks in (never got 41, 66, or 77 to work). If the phone idles it's goes back to 4g/4g+ but under load back up to 5g+ (if anyone knows how to hold 5g I'dlike to know). I live in SF Bay Area including SF day trips.
