Hey guys, just a simple question here. How do I make my phone to choose 850mhz band when network is idle and choose 2100mhz automatically when I use the network. The reason I want this is to reduce battery consumption and increase signal strength. Yes 850mhz uses less power and has more signal due to more 850mhz band cell towers than 2100mhz towers around here.

Hi there,
Can anyone please assist?
Whenever I select a phone Band of WCDMA and am operating on HSDPA [H], my Touch Diamond which is on Hutchison 3's Network, has very poor reception whenever indoors and has lots of call dropouts. The phone shows just the dot below the Antenna Icon or just one bar to the right, most of the time while on HSDPA.
Whenever I select a phone Band of GSM, and the phone switches to an Edge connection [E] then I have nearly full signal strength, but this is considered "Roaming" off my network service provider and therefore is much more expensive to use. (What a scam!).
I have tried installing several radio ROM's but it has not made any difference to the signal strength and dropout problems. The Radio ROMs tried so far:
1.09.25.23 Official (Quad Band)(52.51.25.26H)
1.08.25.20 Official (Quad Band)(52.44.25.24H)
1.08.25.08 Official (Quad Band)(52.44.25.24U)
1.00.25.BS14 Official (Quad Band)
1.00.25.06
The phone has had this problem with HSDPA signals since I purchased it.
My questions are:
1. Have other people experienced this kind of issue and is poor reception indoors normal when on HSDPA [H]?
2. Is there a way to force a Touch Diamond, say through a registry hack, to use a Band of WCDMA but stay on [3G] instead of using [H] ?
3. Is it more likely that my phone is a good candidate for a warranty return as perhaps the antenna is dodgy?
4. Are there any other suggestions I can try to fix this problem?
Any guidance here is appreciated.
Thanks,

I love my Diamond and think that it is one of the best PDAs I have used. Its small size is just perfect for me, and I find other phones eg iPhone, Touch HD too big for me as a phone. I have customised it to the extent that I get no lag issues and it runs really fast.
The one flaw which I haven't been able to fix is its poor 3G/HSDPA reception compared to other phones like my previous Nokia. (The iPhone suffers from this problem also).
You obviously live or work in a poor 3G reception area for Three. When your phone switches from 3G to GSM, it will invariably drop the call if you are on a call. If the 3G reception is strong, indoors or outdoors, there will be no problems. 3G reception can fluctuate especially indoors. I dont think there is any fault with your phone.
Your options are to:
1) Change mobile phone provider
2) Force the phone to use GSM in low 3G signal areas and you will have no problems with call drop outs. There is no extra cost for roaming in GSM with Three for calls, only for data.
I use option 2, since I use WI-FI in the house for all my data needs. The easiest way to do this is to use Comm Manager, under Settings, Phone, Band, and then select GSM in 'Network Type' to force it to use GSM, or WCDMA to force it to use 3G/HSDPA. The other option is Auto, which is the cause of the problem. I use a hack which enables a '3G' toggle in Comm Manager so that I can change from 3G to GSM with the simple touch of a button.
You will also find that the battery life of the Diamond is really poor when it has to constantly change from 3G to GSM and vice versa. On the other hand, forcing it to use GSM and only switching on 3G when you use data, will actually prolong the battery life. I get up to 2+ days battery life when using GSM only.

Riker88, appreciate your comments and feedback. Thanks.
I tried my 3 SIM in another Touch Diamond and found the problem with poor HSDPA reception on Hutchison 3 was exactly the same on the other phone. This likely means it's the provider, or phone + provider combination. In either case, darn it !!
I generally operate with the phone band selection on WCDMA, rather than GSM or Auto. I noticed yesterday while driving around the city that my phone switched from the HSDPA (ie. 3.5G) service with the [H] icon on the screen to the 3G (ie. 3.0G) service with the [3G] icon on the screen, and the [3G] service signal was stronger. What I'm wondering is this:
Is there a way to force the Touch Diamond to use [3G] all the time, instead of [H]?

From my understanding, you should get same radio signal strength no matter it is 3G or HSDPA enabled. Your observation may be your original signal (with HSDPA) is too weak and hand-over to another radio station that have stronger signal but no hsdpa.
I also notice that the 3G reception capability of diamond is weak. But this is nothing dealing with hsdpa.

From what i've seen - that's true. (i have the same problem).
Is there any way to get my Captivate to stick to 850 band only, and not switch to 1900. I live in an area where I have 3G coverage on both bands.
Edit: I can get to this using SGS tools, but that would be only till a restart. Any way to get this to stick permanently until disabled.
Go to the phone dialer and put in *#2263# from there you can select what band you want. To check if it took, type *#0011#
Yes.. what he posted above should work even after reboot
The moment I set to 850 its switching from 3g to edge. Strange. Cos when on 3g mode its always been on 850, atleast 80% of times
Sent from my SAMSUNG-SGH-I897 using XDA App
Thats one thing the bugged me is that this phone ... AT&T version anyways.... loves to camp on 1900mhz more and would be fine if it would switch to 850 when needed..... alot of time I would be at -111db and still on 1900 when 850 in the same are would be at -103db.
I enable 850 that way but once you reboot... you need to do it again.....

Technically, the lower band should have lower signal strength reducing radiation. Plus should be using less battery power. That is why I am seeing how to get to 850.
Anyways, I think I'll leave it how it is.
Ok so I know that the C6903 doesn't support ATT's main LTE band.
Should I just use WCDMA (preffered)/GSM? will this save me some more battery? I heard LTE will kill your battery faster, so since I can't get LTE in most areas should I switch from the LTE preffered in the mobile networks settings?
Hi. Can anybody help me on how can i achieve this? the problem is in my country 2g 850 has limited range but for some reason my phone uses this band instead of using the more spread 900. Sorry for my english.
Hello guys,
I'm using Mi9T Pro with Stock EU rom MIUI 12 version 12.0.4
I have this issue with Xiaomi regarding how the system handles prioritization of Network Band when it comes to using Mobile Data connection.
We know that we have options to prefer 4G, 3G or 2G. But it doesn't define which specific band. Like for example, 4G can be 4G/LTE or 4G+/LTE+. These 2 networks seem to be the same but these actually have different network bands
The question is how does Xiaomi system prioritize which band to select?
Does it prefer the one with higher signal or the one that pings better.
I have this question because as I have experienced, Xiaomi system seem to prefer the one with better signal regardless if it can't even pull any data. In short, it will keep connecting to a network with a better signal strength even if you won't get any internet connection out of it.
I've been noticing this when I set my phone to 4G preferred in my location. When signal indicator turns to 4G/LTE. It may seem to show you that you're connected to the internet but you can't really browse anything because there's actually no data for that band. But when it turns to 4G+, that's when I really get to connect to the internet.
And the biggest problem is that the system prefers to connect to the 4G band. That's why I'd prefer using 3G network because I have a more stable 3G+ signal here.
Another thing that's really disappointing is that my other phone OnePlus 5T handles this well. We share the same APN.
Sadly there's no band selection in *#*#4636#*#*
It would be glad if anyone could provide a better solution to this.
Thank you!

4+ g usually means (specially on Xiaomi phones) LTE Advanced Carrier Aggregation where no other/different bands are used but instead the phone is in parallel attached to more than one 4g band. As such, it increases the speed (and maybe, in your case provides a fail-over?!):
https://www.gizbot.com/mobile/featu...ifference-between-4g-4g-explained-053769.html
However, there is another question why (on that place) you have strong 4g signal with no Internet, so that when your phone switches to CA and in parallel attaches to another 4g band (maybe with a weaker signal) it obtains Internet connection over that second band
At least to better understand on which band (at which place and which base station) you have a 4g signal but with no Internet connection, install an app like Network Cell Info Lite, LTE Discovery, Net Monitor Lite). I think with Net Monster (all apps are on Playstore) you can even see on the map where is the base station you are attached to
If your phone is rooted, you could use Network Signal Guru that will show you, in case of 4+g all bands you are aggregated to with their signal strengths, base stations locations, etc (apps above would always show just one, primary band):

Ohhh thank you for this explanation.... Someone actually mentioned aggregation to me also. This helps make me clear up how Xiaomi does this and that. Does this mean force selection of network band won't work on Xiaomi devices?

I'm pretty sure that with MIUI 11 there was an option to disable/enable 4+, but on MIUI 12 (12.0.2 QFJEUXM) there is no more that option
I don't know of other options (except to prefer 4, 3 or 2 g), specially about selecting bands
choose band mode
