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 ...

I will say yes, but, that answer doesn't necessarily hold true 100% of the time. It really depends on the bands that the device supports. On the device spec sheets you will usually see something like this: 800/1900/700 These are the bands that the device will operate on. I pulled these numbers from the Droid Bionic. From that spec sheet, it goes even ...

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.

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 ...

Is that true? Yes, this is true. The USA is currently using the 700, 800 (Sprint only, I think), 1700 and 1900 MHz bands for LTE service, whereas European providers are using 800, 900, 1800, and 2600 MHz (Wikipedia). If it's true, can the US variant be persuaded to work in the UK, 4G-wise? I'm not shy of flashing custom ROMs and so forth. No. The ...

Often times, one of the main differences between Android phone models is the supported frequency bands. This can be because they simply use different antennas for different bands, or because they support completely different network standards (e.g. CDMA and GSM versions). It is not uncommon for devices to be released with completely different names on ...

The HTC Evo does not contain any LTE hardware, so it wont work

First, WiMax and 4G are completely separate. WiMax already has real-world implementation, whereas 4G does not; 4G is still in development. Second, 3G LTE is also completely separate from 4G. LTE also has real-world implementation. A 3G LTE phone can only operate at 4G speeds if it has hardware capable of it. The manufacturer will undoubtedly advertise ...

I have a Nexus S for T-Mobile, and I've enjoyed it so far. There's only been one update for the Nexus S so far, to 2.3.3. I didn't get it the first day, so I installed it myself. Unless Sprint turns it off, you should be able to tether. I can both over Wifi and USB. I have never needed to root, and I'm a rather advanced Android user. You can unlock the ...

In the HTC Dream (G1) the UMTS radio (3G) is a separate board from the rest of the phone. While this is a Desire Z and I haven't had the opportunity to take one apart, it's probably very similar. The 3G/4G daughterboard (or if it's connected, antenna) could have failed, cracked, disconnected or sustained damage in some other way. Software won't fix it. You ...

It's hard to say without knowing what specific model(s) you're thinking of, but by and large the antennas you're thinking of are probably designed for 3G/EVDO, in which case the answer is no. Sprint's WiMAX network operates on a completely different frequency than it's 3G network, so the antenna for one will not work for the other. The EVO itself has two ...

Yes, the current Verizon 4G phones all have support for the 3G network. As Matthew Read points out, it would not make sense until 4G coverage is available everywhere that 3G is. If you have an active data connection, your phone will get a new IP address when it lands on the new network (4G->3G or 3G->4G); apps must be able to handle this event (any app ...

You can use the code *#*#4636*#*# in caller app, you will find a menu called 'Testing', enter in phone information and then in 'set preferred network type' select 'WCDMA only' or 'GSM only'

I don't know of a user interface in Android to enumerate the radio frequencies that the device handles. However, to give you the direct answer you were looking for, the Padfone X lacks UMTS 1700/2100, which is different from the LTE 1700/2100 that it supports.

The "bars" actually just state the signal strength – so basically you could have all 5 or whatever bars, but no data at all. Data speed depends on multiple other factors not all fully known to me; one example is "available bandwidth" divided by "connected devices using it". So if the capacity of the cell tower has been "reached", even with full bars and ...

That's not a bad idea at all. I have Verizon Wireless and I do this all the time. That's what tethering is for, and the USB option as well. 4G is fast, and for what it's worth, based on what you've said, it seems like a fantastic idea. To answer your second question and forward, no - - your phone wouldn't fry, providing you got a phone with good specs. ...

I don't think it makes a difference which Android version you use: the support for 4G is provided by the cell radio drivers, added to the system by the manufacturer. The Samsung Galaxy S Advance does not have the hardware needed to use 4G networks, so upgrading the OS won't add this support, and there's no way a third-party app can do that either. If you ...

While this is sort of a "shopping" question, it is also a question about if these phones will work on t-mobile's network. T-Mobile does not (currently) have LTE. So if the device has LTE, you will not use the LTE chip. Will the devices work on T-Mobile? Yes. Will you get the T-Mobile 4G speeds? Well that depends on what bands (or frequencies) the device ...

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: ...

You don't need the US phone to begin with. If you're just looking for the RAM: According to a Cnet article the UK Version has 2GB of RAM. Apparently the international version excluding US also has 2GB RAM.

I would not read too much into EE's rollout of 4G just yet, for starters, the frequencies are different, give that time, EE and other 4G operators in the UK would have the final say on the compatibility of the handset. Here in Ireland, 3 and Vodafone are planning a merger which would see the in-evitable 4G being rolled out - do not know when yet... Stick ...

It seems the issue is network authentication problems caused by Verizon's switch to a UICC SIM-based authentication for both 3G and 4G connections on all of its 4G LTE devices. See this article: http://www.androidpolice.com/2011/12/19/this-is-why-your-verizon-galaxy-nexus-or-other-4g-lte-vzw-phone-is-losing-data-signal/

At least for the Droid Bionic, this appears to be a known software issue. This post on the Motorola support forums includes the following listing. Marginal 4G to 3G transition: Loss of data connectivity - The device may display 3G service indication but no data connections are possible. Action: The user will need to power cycle the device or ...

Even on Sprint, LTE will be supported through new devices, just like on all the other carriers. WiMAX is a different technology. Because they are both called 4G is irrelevant. HSPA+ is called 4G, too, and is also not the same as LTE (or WiMax),

While I'm not intimately familiar with Sprint's 4G or your phone (sorry) I have found in my own CDMA troubleshooting that the built in HTC diagnostic tools can be very useful. I found this guide over at XDA as one of the better lists of Sprint CDMA diag codes (even though it's not for your phone specifically). I recommend trying ##33284# or ##3282#, one of ...
