I have a rooted mt3g, is there a way to switch the network tower you are using.
I remember with my old basic bar phone i could go into settings > network and scan for available networks, and i was alwasy able to jump on att/cingulars towers and it of course would not charge anything it would just use their network. It happens a lot when i travel a lot it will automatically pick up the strongest/nearest GSM tower but i could also do it manually.
Is there a way to do this on this phone?
this is by no means a definitive list, but here are a few links to articles i have read that have helped improve my battery life drastically. if you have any other useful information, please share.

instead of thinking, 'i need to replace the battery because it doesn't last long enough', try thinking 'how can i use my phone in a manner which doesn't unnecessarily drain its battery'.

I found a tip about reconfiguring the radio settings here:
community.htc.com/na/htc-forums/android/f/96/p/7495/34268.aspx
"I have an HTC Aria, I found out that the radio is setup completely wrong (power hungry) by default. I can now get over 48 hours of moderate use out of a phone that was barely able to make it to 12 hours before.
First of all, on AT&T, GSM (which is the 2.5G EDGE network) is much more power efficient than CDMA (which is 3G).
The default settings for 2-3G, have the phone constantly trying to find the strongest CDMA tower-signal it can find for 3G. If it can't find any 3G, it switches to 2.5G (EDGE). This eats your battery and is why your fancy new smart phone has a usable life of only 8-12 hours.
Now, the reason that your phone is always searching for the best signal is that, in area with only average coverage, the phone will always be trying to get you the best connection. This makes AT&T's 3G feel fastest and you will always get the most 'bars' available - at least while your phone's battery holds out.
Luckily, some engineer over a decade ago came up with a solution. Instead of scanning, have the phone ask the current tower for a list of nearby towers. This is called a PRL.
The way the PRL works, the phone contacts the tower to which it is connected and asks the tower for a list of nearby towers and their power outputs. Then the phone will base its decisions to switch towers based on that list.
Where I live, 3G is everywhere and making the phone constantly search for a better tower is a waste of time and energy. So instead, I switched my phone to prefer GSM (ie. EDGE) over CDMA unless there is a poor signal, then it switches to scanning for 3G (which supposedly has more range and less interference) just like it used to.
The settings to do this are normally hidden by the carrier. For AT&T on the Aria, I had to enter a USSD code:
*#*#4636#*#*
Then select Phone Information from the menu. The drop down you want is called Set preferred network type: and the option I selected was GSM/CDMA auto (PRL) and my battery life has been fantastic."
Has anyone tried this? How did it go?
Thanks.

I'm not sure about the stock rom, but on cm roms there is the option to add this option into the power widget bar and makes switching between modes a one click affair. I keep my phone on 2g (gsm) unless I'm trying to watch a video. It definitely helps.

I am trying that out and using GSM (PRL), it seems to do very well, and automatically switches between HSDPA and EDGE
Just switched mine from WCDMA preferred to the CDMA/GSM Auto (PRL)
I'll see how it goes.
that battery has lasted longer than usual, even with the extreme cold of the midwest, since I was shoveling for 3 hours. 8 hours off of charger, moderate use, still at 80% with GSM (PRL) on
tried the GSM(PRL) thing, works great! thanks for this thread
Been noticing the drain, too. I've switched to CDMA/GSM Auto (PRL), but it still shows the "H" at the top? I think that's correct, but wanted to ask.
So how often is it kicking you guys to EDGE? It may give you better battery life, but your data will be slow as hell if you aren't on 3G no? Or do you guys not care?

I switched to cdma/gsm auto (prl) about a week ago and mine hasn't switched over to Edge at all.

I have know idea how to do this. I dial *#*#4636#*#* and it calls it and says blah blah wrong number. Can somebody explain please. I'm a noober on this one.
"the only good bug is a dead bug"
Figured it out. I use dialer 2 app for my default phone. Apparently you have to use the stock dialer to enter ussd code.
"the only good bug is a dead bug"
Is it possible to write an app that will force your phone to log on to a specific cell tower and ignore a closer stronger signal?
The test phone is a prepaid Verizon Moto g.
The phone will be stationary so dropping calls is not an issue.
I want the phone to stay locked on to the selected tower, even if a stronger signal magically appears and tries to lure my phone to it. I am thinking criminals or the Feds with a Stingray or a portable Managed Access System.
Hi everyone,
I already looked for an answer in the forum but nothing conclusive.
My moto g4 play loses signal during calls. The sim card is 3G and so I changed the network manually to 3g on the phone. However the problem continues and I think it even got worse. It happens especially when I'm moving, in the car, etc.
Is there any real solution for this problem? I have seen many users complaining but I did not realize if there was a solution or not.
Can you help me?
Thank you
Since the SIM is 3G, I'm going to assume the network you're using is GSM (ATT/Tmo). It is possible that the cell towers in your area operate on a specific type of GSM frequency, and your signal loss is due to the phone trying to connect to towers not supported by your carrier. If a call drops again, check the Roaming status of your phone in Settings and see what turns up.
Also, it seems odd that you would have to change the network settings at all. Even if the phone is set to prioritize LTE, it should automatically detect the 3G signal and adjust accordingly.
Like the title says, the H910 connects to any network when the selected/preferred network is not available or has low signal. It doesn't matter if you manually select a network, if the signal goes very low it will connect to some other network.
The result is that you see "bars" but is not connected to the intended network and you may not realize that you are out-of-service. With an AT&T simcard you cannot select a network but even when traveling with a foreign sim (where the network selection is available) is still doing that.
Also, when is connected to the other network, you don't see the network name and if you try to make a call you get the "emergency calls only" message.
Probably this is considered a safety feature. Is there a way to turn this behavior off? I want my phone to be out-of-service if there is no signal. Especially since the signal at my home is very marginal lately and I would like to know whether I have service or not (at the moment I assume that if I see more than 2 bars that I don't have service).
