Let's state all the possible letters in the signal indicator, in descending speed: LTE = Long Term Evolution (commonly and falsely known as 4G) H+ = HSDPA Plus H = either HSDPA (3.5G) or HSPA+ (3.95G), depending on your network provider 3G = UMTS (3G) E = EDGE (2.5G) G = GPRS (2G) (no letter) = voice only, no data connection and also: R = roaming (this ...

Fast answer: Nes. Yo. Well, it all depends... on how you use your device. Detailed answer Self-Experiment I just did a self-experiment to find out. Until now, I had all my devices fixed to 2G -- as that should "save juice", like the question suggests. So for 4 days now, I have 3G enabled. Surprisingly: No difference which could not be explained by ...

I did not find a way to reliably do it without an app. I often use OpenDNS Family Shield, but sometimes it blocks me to visit some particular hacking site and then I need to quickly and easily change the DNS servers. I used to use Set DNS but it stopped to work in Android 4.3 and further, so I created Override DNS, a new app which mimics Set DNS' behaviour,...

I know of no way to restrict an app to the 3G network (as opposed to 2G/4G), but there are several solutions to restrict apps to either WiFi or mobile networks (or keep/allow them from/to both). Examples include DroidWall - Android Firewall1 (which you already mentioned, but which is discontinued), its successor AFWall+2, its fork Android Firewall3 (gone), ...

I faced similar problem until recently I found the fix. I use Vodafone 3G Pack. If you are an android user, check the network and settings -> Access Point names In that check if APN is set to Vodafone Live. If yes, change it to default settings and it should be changed to vodafone Mobile connect. Also, then check the value of MCC and MNC. It should be as ...

Simple answer: No. 3G (also called UMTS) is a different techology than 4G (also called LTE). Both technologies don't share any common base technology (starting with the frequencies and going over to the encoding technologies). So your carrier has two different nets, one with 3G and another with 4G. If you are lucky being near a 4G base station you have an ...

i also had the same issue. Incase you are on vodafone network, try and select vodafone gprs as ur default settings. It worked for me the same way. Hope this suggestion helps

The Short Answer Nope, not possible, or at least compicated & tedious, because Android defaults to WiFi since it's generally faster, more reliable and has no data cap However You may want to look into this app. While it requeires a rooted device, it allows you to leverage on both your WiFi & 3G to download at the same time. The Long Answer As ...

I had the same issue. Found this solution on another site: Open "Settings" App Go to "SIM Card Manager" Tap on "Data Service Network" Choose the SIM as the Data SIM Note that only the first SIM slot supports 3G Internet. So if you want to use 3G you must plug your 3G SIM in the first slot.

Just disable captive portal detection. In the terminal, or in adb shell, issue the command settings put global captive_portal_detection_enabled 0 and reboot.

Parts of those build.prop tweaks (and several you did not mention) are explained in the attachments to this XDA post. Let's see what of yours is covered – which are mostly the RIL settings (Radio Interface Layer): ro.ril.hep : unknown and undefined … may not even exist ro.ril.hsxpa : 1:HSDPA, 2:HSDPA/HSUPA, 3:? (HSUPA only?) ro.ril.gprsclass : see: GPRS ...

Starting with Android 9 Pie it is possible to change DNS globally, provided they support TLS. Just go in Settings → Network & internet → Advanced → Private DNS

If you get a device working on a specific carrier or not depends on the following factors: cellular standards and frequency bands artificial locks on the device and sometimes willingness of the carrier First, check what your future carrier and phone have. For carrier networks and frequencies Wikipedia is the most complete source I know: http://en....

Android will always use WiFi once it is connected. You just have to disable mobile data. To do so go to Settings → Mobile network settings and uncheck Data enabled.

To manually start and stop internet: Go to Settings -> Wireless and networks -> Mobile networks and disable Mobile data. This will stop internet connection through mobile network. Enable this to start internet again. To stop it permanently: Some application may start internet automatically, So to prevent accidental internet consumption, Create a new ...

Turning off 3g and reactivate it later would consume less power, as all the data can be fetched once the 3g radio is in the high power state When it is left idle, even for the most trivial data transfers, like checking the weather, the same cycle has to be repeated. Because of the long tail time that holds the device in a power mode, transmitting data as a ...

Apps that use push notifications, such as the official Facebook app or Google+ Hangouts, don't need to repeatedly check for new messages. The server sends new messages to the phone when they arrive, without having to be asked. My answer to 'How do push notifications work?' describes this in more detail. What you're asking about is apps that poll for updates,...

your phone doesn't support 4G it supports 3G++ which almost 4g and supports high speed downloads , the short unswer to your question is you can't use the 4g plan proposed by your carrier due to your phone's hardware limitation. the bright side is HSPA+ is not so bad you will not notice the difference.

This info is from 2014. But it might still work. I am not in the position to test it at the moment, but since you are rooted. You could try adding the dns settings to the build.prop file and see if it sticks. Adding the following to the build.prop file should add google as your DNS server. net.rmnet0.dns1=8.8.8.8 net.rmnet0.dns2=8.8.4.4 net.dns1=8.8.8.8 ...

I figured them out thanks to here and here. GSM is 2G (on GSM networks) WCDMA is 3G (HSPA) CDMA is 2G (on CDMA networks) EvDo is 3G (on CDMA networks) TD-SCDMA is 3G (UMTS) LTE is 4G (LTE) This PDF (page 16) explains the evolution of the different technologies. Warning: A lot of this terminology is conflated (e.g. "CDMA" can refer to both the channel ...

That's easily accomplished using Tasker. If you don't know, Tasker is the most complete automation solution for Android. It doesn't come for free (5 Euro -- but you can get a free trial on their homepage), but is definitly worth the price. Just take a look at the Tasker UserGuide for a full description. Tasker combines conditions and tasks to profiles. In ...

I think USSD Checker is the app that you are looking for. It allows you to send USSD codes to your network without the use of a dialer. I haven't tried it myself though so comment whether it works or not would help.

Officially: This is not possible, except for certain (older?) Archos tablets. Inofficially: There's the Autopatcher project . It includes patches to enable 3G modems on wifi-only tablets (it may be possible to use those on phones too, but YMMV). Autopatcher supports these Android firmware flavours: some 3rd party firmwares (CyanogenMod, AOKP, ...

The radio frequency of a 2G radio operates in the range of 900 and 1800 MHz (source)- varying from country to country. The radio frequency of a 3G radio operates in the range of 2100 Mhz (source). As far as Samsung Galaxy Nexus LTE L700's specification is concerned, the 2G frequency is CDMA 800 / 1900, 3G frequency is CDMA2000 1xEV-DO and LTE (4G) ...

With Xposed module and Gravity Box installed, the pull down status bar can be customised even on stock ROM (of course it has to be rooted). I have a Nexus 5 running stock 4.4.4 and following is how it looks: With these installed, one can swipe down with two fingers from top and just tap the last tile shown as "3G" in the image. Though this nearly misses ...

Opera Mini has options to enable loading images and also to specify the quality of images, if they are loaded. If you are rooted: Installing a firewall(like DroidWall) helps to prevent unwanted apps to access the network. Installing an adblocker(like AdAway) will prevent ads from loading, and in turn reduce network usage.

To limit the bandwidth, switch from 3G to 2G. You will still have internet connectivity but It will be slower, hence taking a longer time to use up your monthly internet traffic. The bonus is that using 2G will probably also increase battery duration as it consumes less power than 3G. On the other side, you can install a browser that has an option to load ...

Depends on network provider. From Nexus 7 2013 LTE Variant Available Now for $349: Keep in mind that you won’t be able to fall back to Verizon 3G at any time, but you can fall back to AT&T and T-Mobile HSPA should you choose their service. From Google's Nexus 7 with 4G is now available in the UK: Buying from O2 is a different story, however. The ...

I programmed Llama to do exactly that. You'll need two events: 3G auto on 3G auto off and one Llama variable: auto3G Event 1 (3G auto on) when airplane mode is disabled [prevents the system to work if airplane mode is enabled] when mobile data is not connected [this ensures there will always be a break of 60 minutes after each (manual) data or wifi ...

Keeping your IP address and using a VPN is the complete opposite of what VPNs are invented for. VPNs make you part of a network through a tunnel connection so that your phone is on the same level as locally connected devices. This means your IP address will be the one of the VPN. If you don't like this, then you should not use a VPN. Also check your IP on ...
