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 ...

Whether or not you can use a phone on a specific carrier depends on a variety of factors, but it is generally possible to figure it out provided that you can find enough information on the device and carrier you are interested in. The main points to focus on will be the cellular standard the carrier uses, the frequency bands it uses, and the associated bands/...

It's HSDPA which if I'm not mistaken is referring to 3.5G.

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,...

Yes, 3G traffic will go through your VPN if it's set up correctly. Whether or not your service provider supports that is another matter; some block VPN traffic (such as Verizon - see this thread).

Despite the wide-spread information of its impossibility, an app named Super Download claims to be capable of this, as you can read in the article Combine 3G 4G Mobile Data + Wifi together to Boost Download Speeds at Geeknizer. As expected, this comes from one of the XDA developers (elban) -- and, also expected, it requires your device to be rooted (not an ...

Short answer: yes. It depends on the currently enabled Wi-Fi sleep mode. By default, Android disables Wi-Fi when your device goes into a sleep. In this case, 3G is the remaining mode of network communication, and it gets used by Gmail/Gtalk push notifications, etc. Obviously, this network communication takes its toll on your battery time. If you disable 3G ...

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), ...

Since the nature of your question is simply "is this possible", the answer is yes, there are ways to spoof your ESN. Often this is a form of phone cloning, which is also simply referred to as ESN cloning. The concept is that you take one phone and then configure it to broadcast using the ESN of a different phone, effectively "cloning" the second as far as ...

Your understanding is correct. GPRS < EDGE < 3G < HSPA. HSPA = HSDPA (High Speed Downlink Packet Access + HSUPA (High Speed Uplink Packet Access) The difference between the three lies in the bands i.e. frequencies they use to communicate with the network. Edge uses the same frequency as the phone uses to transfer voice and SMS to the network. ...

Yes, it has HSPA+ which is what T-Mobile's "4G" actually stands for. This article on AndroidAuthority should help you understanding why it doesn't have LTE.

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 ...

While this might not be the complete answer to your issue, it appears that the Galaxy Nexus is connected to an HSDPA:9 radio (10.1mb/s theoretical speed) while the Milestone is connected to an HSPA radio (14mb/s theoretical speed, not HSPA+ which can have a theoretical speed of between 21 and 42 depending on the network). While the theoretical capacities of ...

Yes, your phone supports two ways to export its internet connection via bluetooth: DUN-GW (Dial-Up Networking Gateway) PAN-AP (Personal Area Networking Access Point) See also this question (its answer about bluetooth). In short: PAN is supported from Android 3.0 onwards as client. Android <3.0 users may have luck with Wireless tether for root users. ...

If you have an (W)LAN network connected to an ADSL modem at your home, a mobile access point is like that ADSL modem; a mobile access point (AP) translates between the protocol of the mobile network to the protocol of the wider Internet. Imagine the mobile network as a LAN, and access points are the nodes in the LAN that have direct access to the Internet, ...

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 ...

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....

There's an app for 3G only mode: https://play.google.com/store/apps/details?id=com.mobnetic.only3G However your phone should automatically try and go for 3G if there's a 3G connection available, it will never choose 2G over 3G so I don't see why this would be useful... There's still a 2G only mode to save battery in Settings -> Mobile Networks

I don't think there is such option in Android, but if you know your phone's model you could always google it. For instance, if you look at Wikipedia article about Galaxy Nexus, you would see that it supports all four GSM bandwidths (850/900/1800/1900). Just have a look at "Compatible networks" section in the box on right side.

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 ...

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.

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 ...

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.
