Hi,
I have a business trip coming up to Saudi Arabia next week. I know that my cdma evo won't work there, but there are quite a few WiMax providers in Saudi Arabia. Can the EVO be reconfigured for a different wimax provider if I was to pay for a plan with them? Would love to have data while out there..
Thanks,
-mark
If i'm not mistaken, wimax functions like a broadspectrum Wi-Fi, It should automatically find the signal, but you would need your phone to be registered in their system for it to accept the connection request. I could be completely wrong, but that is how i believe the connection works.
You should be able to edit the network settings through EPST if you're running a Sense ROM. I don't remember what dialer code it is.
The main issue would be the radio frequencies. Do you know if they're the same as Sprint's/Clear's?

So after researching the functionality of WiMax, it wont be a frequency issue, WiMAX works like WiFi, in the sense that any WiMax device can pickup any WiMax signal, it then falls on the carrier's side to allow the device to connect. WiMax runs on IEEE 802.16, similar to Wi-Fi which uses 802.11.
www.wimaxforum.org, and a full sitemap of Wimax locations can be found at www.Wimaxmaps.org
Now what this has also been able to let us know is that Saudi Arabia does not have a Mobile Wi-Max infrastructure, they have Fixed/Nomadic Wi-Max which requires a person to be stationary in the vicinity of the signal. 802.16e is Mobile Wi-Max, and 802.16d is Fixed/Nomadic Wi-Max. Now I don't know whether or not the EVO is capable of receiving 802.16d wireless signals, just like some 802.11 cards are labeled a/b/g/n because not all cards are capable of viewing the same revision.
If the EVO is capable of receiving 802.16d signals, then it should only be a matter of finding out from the Wi-Max provider in SA as to what they require for you to be able to access their WiMax network, if anything at all.
The attached Images show the Mobile WiMax frequencies that are broadcast in the US, and the Fixed/Nomadic Frequencies that are broadcast in SA.

Thanks for the clarification. You're right - I hadn't seen any mention of mobile wimax - just wimax @ home there..
cheers,

There are more reasons it won't work:
- WiMax can be deployed on multiple frequencies. If they don't match, it won't work.
- I don't know the exact details of how this is implemented, but when you connect to Sprint's WiMax, there's an encryption key exchange. I don't know if that's just intended to keep other WiMax devices off of Sprint, or if it also prevents your phone from negotiating a connection with something off Sprint. In other words, even if the carrier isn't trying to negotiate with a key, is the fact that our phones are programmed to use that key in the connection process going to cause a problem? I don't know the answer to this.
- If the carrier you're trying to connect to requires a similar handshake, you wouldn't have the right key on your phone to do that.
- There aren't any global roaming arrangements for WiMax as far as I know. That carrier doesn't intend to let you use it if they can't get paid, even if no technical restrictions prevent it.

I had my Desire over a week now. I was just wondering, if the desire had a hidden WiMAX feature? Im only asking because if you go to
Settings -> Applications -> Manage Applications -> HTC Sence and scroll down to system Tools you'll see change WiMAX state.
And also when Paul from Modaco released the HTC Desire ROM for the Nexus One he said that in the kernel he found something similar when he had the camera problem
What do you think??
PS he's a link to Modaco's forum about this

Well it's sort-of 4G in a marketing sense... from a network engineering sense LTE is 4G and WiMAX is not LTE for sure.
But then again, in engineering terms there's no such thing as 2.5 or 3.5G either, they're just dumb marketing terms that people who don't know better fire off left, right and centre...
we find wimax icons in the windows folder in hd2 http://forum.xda-developers.com/showthread.php?t=655518
I can also confirm the existance of wimax settings. If you install AndLock from the market (a very good app protection app) and select 'Settings' from the default applications list, it will allow you to set up pin protection for '4G settings(.wimax.WimaxSettings)' which is found at the very top of the 'Activites' list. Is this likely to be code that has been copied over from the Evo, or has the desire been made somewhat futureproof and made capable of WiMax? Not much use here in the UK at the moment, but might be of use when travelling etc.

It's purely for the EVO.
WiMax *is* a 4G standard, but no European cellular networks are expected to implement it and will use LTE instead. In the UK, there are some small providers who have implemented their own WiMax networks to provide local "m mobile" broadband (e.g. Freedom4), but that's about it.
Even in the US, Sprint has deployed a WiMax network via it's partnership with Clearwire, but it too is expected to go LTE eventually.
Regardless of that, there is no WiMax compatible radio in the Desire anyway!

In Norway I live close to the border to Sweden. I have to roam in my area to a Norwegian Network, because my phone company only have their own network in the big cities here. Before I had an operator the had their own networks in my city.
So when I now roam with the other Norwegian network, I have to disable that "Disable network data when roaming". And sometimes I now get connected to the Swedish network and have to pay 20x times more pr MB.
Is there a way to disable 3G/2G on different networks of my choice?
Hope someone know of something that will help.
Sorry for my English.
Setting-wireless and network-mobile network-dataroming unchecked
Something like this cause mine is in dutch.
Like I said, I have to have it unched cous of my network today is not the default of my operator, so I'm romaing all the time when I use my phone. I want something that can read the operators name and then enable the 2G/3G data connection is it is one of the networks I've accepted. If it's not, then disable the connection.
Cant help you with your roamaing problem, Sorry. But maybe you should consider going back to your old network. If you have no signal at your home you may have the right to cancel your contract.
The clue is that I pay 20£(with use in Norway) until 1.1.2011 to use the phone(sms/mms, calls, MB) as much as I want for only 20£. After 1.1.2011 I'll pay 20£ for 500sms, 500 minutes and 500MB.
But that only works with the operator network and the one they rent(like I use). The one I rent belongs to Telenor, the biggest phone company, as they have the best signal too, I want to stick. But they suck at priceing, so I want to be with my new operator.
But why is it so hard to read the operator name with an app? Than then can enable/disable data connection?
My phone is Desire and it is rooted, running OpenDesire.
Sorry for misunderstanding the first time.
One option you could try is Tasker. I think it has the option to turn data off/on when connected to a certain cell tower. It's not the exact thing you asked for but i don't know any other options.
You have to program it yourself, but just download the app from there site (gives you a 7 day trial) and try it if you can make it work.
Cell Tower, is that the operators ID or the tower itselfe(a operator has many towers)?
I successfully flashed the CDMA Desire with a Sprint Radio off the Evo. It's baseband 2.15.00.09.01
I also installed PRL 60677 from sprint. I also tried the Cyanogen MOD.
It's currently running the alltel ROM so I can get access to the dialing codes in the PRL but even though I flashed the RADIO and the PRL it still shows the network as alltel and it won't let me get access in menu>settings>Wireless networks>mobile network
I can turn it on. But it either seems to take a long time to turn off, or go off by itself, not sure which. But once its on it is greyed out and won't let me get access to it.
I thought maybe it was the PRI, but I don't see how that could be. Is there some sort of Initial Program Loader from alltel doing this can someone tell me why it won't pick up on a sprint network that I have for cdma like connecting or sharing a connection etc... and won't get off U.S. Cellular network?
I might just try flashing to verizon and see what happens just to observe. It should be a lot easier than flashing to sprint.
edit: I did change all the dialing codes to sprint in the ## menu btw. I used the codes from another sprint Phone.
EDIT: It also won't turn off always when I hit Airplane mode and constantly says "Turning on...." and won't give access when to "Mobile Network" when you hold down the power button and that menu comes up.
I used the original Stock RUU to switch back. It changed the baseband and everything else back and also got rid of my clockwork recovery in the process
The only thing it didn't change is the PRL. I had to redownload that and manually rechange the codes in the ## secret dialing menu's.
As far as I understand I will need to change the esn or have this esn to sprint to be able to get it working on a sprint network. It is very difficult thing to do so I will have to postpone this. I'm thinking there might be some code or something in one of the abstraction layers or HAL layers that is preventing you from changing the esn somewhow... not really sure but that seems like the best place for me to look as it is the interface between the software and hardware. The hardware is there and able to do it, so it must be the most basic software or HAL that is preventing me from doing it I am guessing. BTW this is not illegal. I own my phone. If anything it's illegal for someone to sell me crap that doesn't work the way it should because of bogus programming that's been put on my phone to prevent me from using it! And nikola tesla invented the radio btw where is the money and credit he deserves for this?!
Hey man,
I am trying to do something like this for my wife. I'll let you know how it goes once I get the phone. In the meantime, maybe this might help you?

I know it's not quite the same - taking VZW phone onto Sprint Network, but I thought it might help you out.
I'll post my experience later when I get the phone next week.
Thanks,

I don't think that's quite the same thing. I read through the post and a lot of it didn't make a whole lot of sense. Generally you have to have a compabible esn with the network you want to use. Every carrier has a database of all the esn's that are registered and available to use their service. If you try to connect to their service their software will recognize the esn as false and not grant service even if you install all the correct radio's/basebands, PRL files, Firmware, etc... it just won't work because you don't have an esn in their database so you have no authority to connect to their network. So you have to change the esn. But it's not such a simple thing to change an esn. I'm guessing its written in hexadecimal somewhere in the registry, but maybe not. There are certain command sets like the Haye's command set that only apply to CPU or other hardware like modem/Radio. There is an RIL which communicates between a driver, the modem/radio, and the OS. I'm guessing the esn is communicated and retrieved by the RIL layer that communicates via proxy & a driver or in one other PPP protocol that apparently only communicates with the network at certain times suspiciously. That's because the ESN is apparently located in the radio/modem and people have successfully changed their esn by changing their modem and installing a different one. A modem is essentially an ultra small electronic radio. In the same way that a radio picks up signals out of the air and converts to sound, a modem picks up signals also and can convert to sound as well as internet data, text messaging, etc...
If your radio doesn't have the proper command sets it can not pick up on certain signals such as for example sprint 1900 MHz for a sprint radio/baseband version vs a 900MHz signal for a 900 MHz Verizon. Each carriers software might be set up to block the other carriers signals in certain ways. For example each carrier has roaming agreements with the other carriers so that when you go out of your host carriers network say from Verizon into Sprint then you can "roam" and still get coverage. Sprint in this case provides the coverage and therefore they have an agreement to use each others network to provide better coverage. They may also pay each other small fees to use their network. Roaming, carrier type, cell number, mobile network operator, ip addresses, etc... can all be preprogrammed into CDMA handsets through ## secret dialing modes. This only works on CDMA handsets or in CDMA mode on your phone (i.e. not GSM). Usually on HTC devices you press ##775# to update a PRL file which is the Preferred Roaming List. That is usually easy enough, but this may not always update all your phones programming and you may have to do so manually through other ## dialing codes such as Primary HA secondary HA MCC (Mobile Country code) MNC (Mobile Network code) etc... Even if you do all that though it serves no purpose if the esn isn't registered to the network that you want to use. Generally only Cricket and MetroPCs in the USA will register a CDMA esn to use on their handsets. All the other carriers like Sprint, Att, Verizon, etc... generally won't do it, hence you can't get CDMA service from them if you have a CDMA capable handset even if you update all of your files as there is a program that is run on behalf of the carriers that manually checks your phones ESN/MEID/etc... to see if you have the "proper Credentials" or authorization to use their network. In this case the authorization is given on whether or not if your ESN is in their database and that it aslo can be in their database but blacklisted or grey listed in the case of you have an innactive account and need to pay them to get it "white Listed" or if you have a debt on your account or the phone is reported stolen it may be "black Listed". Usually you can flash to Cricket or MetropCs fairly easily though and they will even do it for you for a small fee.
I have a slightly odd requirement, and I wondered if there was any way to fix it:
My carrier has a partnership with a second carrier so we can roam on each others networks for no extra cost.
Where I live, my own carrier only gives me a 2G signal, whereas the other gets 3G. Thing is, I have to physically select the other network. If it's on Automatic, it always "prefers" my own carrier.
This is fine until I'm on the other side of town where the other network gets no signal at all. I then have to manually select my own carrier again!
Is there any way to get it to prefer the other network, or even more ideally, prefer the one that offers the better signal at any given point?
Hi,
a bit of *bump* because I'm struggling with the same issue. I had such option on my previous samsung i780 (oooold) and it worked like a charm.
Currently my mobile operator has 2 roaming partners and if I want to change quickly the preferred order (because in some location it might have better coverage but only there and only for a while) I wold have to switch simcard to the old phone...
Isn't there at even a separate aplication to do that? Does andorid API allow such modification?
Glad I'm not the only one!
Interesting you mention an app to do it... i've not looked actually. If an app can access the list of networks and actually set the phone to use one, then I guess it would be possible. I'll check it out...
to the best of my understanding this is somewhat network option/setting and when suggesting an app I was thinging abount some way to read this setting, modify it and then save/send back to network. It would be a matter of access to the network settings from the API and knowledge how to operate it....
Still investigating this. Looks like the stuff to access the list of networks is in some internal APIs, so a little harder to access. I'll post back when I learn more...
Hey I hope you guys can figure this out have you tried the *#*#4636#*#* command and changed the radio? This will select the most preferred network.. e.g. I'm with Telstra in Australia, the stock radio defaults to 2100MHz but Telstra's HSPA+ is 850Mhz.. so I have to switch to AUS2 radio so it defaults to that every time.

@Simmo3D
It's not about the radio band but about the service provider itself.
Back in the day, I used to be able to see a list on my AT&T Motorola Razr of all the cell provider signals in my area. For instance, if I were in Pittsburgh, I could see the list of available networks compatible with my phone (the phone would apparently create the list from actually getting signal from those cell towers) and if I felt like it, I could switch to a different provider that had a stronger signal.
Now that my gs3 is unlocked I'm hoping I can find a way to see that same information. For example, the AT&T signal in an area might be terrible, but there could be another provider that will give me "roaming" coverage with a better signal. I would then switch to that roaming coverage voluntarily on the fly.
Anyone know of a way to do this? Under settings / more settings / wireless and networks / mobile networks I find "network operators". Currently only "default setup" is listed there. But this is where I'd expect to see other network signals that my phone is getting.
