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 ...

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 never really did a precise comparative test but it is clear that wifi uses way less power than the 3G data connection. So I would recommend to use wifi whenever possible if the goal is to extend battery life. The only exception I would see is if you often use the phone but for a very short moment at a time, the delay it takes for the wifi to connect can ...

Just kill the APN Connection settings. Somewhere under settings. And there is actually a switch for mobile internet. Disable that as well. Worked like a charm for me. If you can't find it, add the Power Savings widget to your home screen, it has that option

If you choose 3G only, you have no connectivity if you are in an area where no 3G is available. With 2G+3G, the phone will fallback to 2G if it can't get a 3G connection.

First be aware that you're transferring data over a wide area wireless device (the range of 3G is much wider than Wifi), therefore it is easier for an attacker to snoop on whatever your device is transmitting on 3G than on Wifi. The 3G/GPRS only has a lightweight encryption (to limit unnecessary use of CPU power and battery, which is already scarce in mobile ...

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).

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 ...

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 ...

If you have a rooted device you can filter which specific apps can access the 3G connection with DroidWall.

I can't remember where I read it but I read that 3G will use more power when transfering data but wifi will use more when idling. I tend to keep wifi on, but if I'm running low on power I'll turn it off to avoid the power requirements of scanning for new networks. Also as others have posted, 2G will use less power than both unless you're downloading large ...

On my Galaxy S, you can hold the power button for a second and a menu will come up. Just hit "Data network mode" to deactivate it. You can reactivate it the same way. If you don't have that, you should be able to go to Settings -> Wireless and network -> Mobile networks and uncheck Data enabled or Use packet data or similar.


5

It depends. Try with your particular phone. Maybe download a large file and see how much the battery drains, then repeat for the other data type. Factors include how many cell towers are nearby, how many packets your WiFi drops, your specific chipset and radio hardware, software drivers, and the like.

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 ...

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.

This is set in hardware, there is nothing you can do about this. You can learn more about this in http://www.google.com/support/forum/p/android/thread?tid=395c29e6b9cab6bc&hl=en

This sounds like something that you need to make sure your operator has enabled on your contract, normally with smartphones a data plan is a data plan, once you've got one they give you a (monthly/weekly/daily) bandwidth limit which you can use either on 3G or GPRS, the operator doesn't care which you use. It sounds like you don't want to pay for a monthly ...

I use APNDroid (Also available in the marketplace for free). You can easily turn data on or off with the press of a button. Add the APNDroid widget to your home screen to easily turn data on or off.

There's currently no way to set a system-wide policy for this. Some apps do support doing things on WiFi only, however. Here's some info on the apps you mentioned: You can go into the browser settings and uncheck Load Images. GMail does not load images unless you view a message and click a button to display them. I believe the Touiteur Twitter client ...

The problem is, that my android device automatically turns off the 3g connection as soon as wifi is available. Why don't you shut off Wi-Fi? Since you can't control port forwarding or anything at work, there's not much else you can do. Although, you could just ask and see whether they'd consider opening the Google Talk ports (443/5222/5223).

2G+3G is not recommended if you're in an area with spotty 3G coverage, as a radio switching back and forth will drain the battery much quicker. This is the major reason this widget option exists, to allow users to switch between 2G and 2G+3G on the fly.

No. This completely disables all data access. Only calls/messages can be used. EDIT: You might try looking into something called JuiceDefender. The free version will disable your data access when your screen turns off. Good for both battery saving and data-usage saving!

I use the Power Control Widget. Allows you to toggle Data, wifi and various other settings from your home screen.

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 ...

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, ...

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. ...

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 ...
