[Q] HTC evo 4g NORWAY - EVO 4G General

I manged to buy an htc evo 4g from the us. Ofcourse I didin't know the phone was a sim free phone!=) Aniway..
Norway have all the net htc evo 4g needs to work accept 4g..
cdma,edge,turbo 3g,3g...(3gs) cdma 200 1rtt...
The problem is the sim card..but I refuse to think there isint't one guy here at the xda that cant mix something up!
Some how possible to like use a sim card reader and install the sim card in the phone some how..
after some reseach i understood the the sim card holds information that connect the phone to its operator as for me (telenor norway) so its possible to ring, send sms and mms.
so teoretlic it has to bee possible at least i hope..
really hope for some positive answer

Just to let you know, for CDMA it's not a SIM card, it's a RIM card.
Anyway I think let this be a lesson to you that CDMA phones sold in the States are NOT RIM-replaceable. Only a few countries in the world that will let you do that.
Your best bet? Well, if you know anybody that works for your CDMA provider, he/she maybe able to manually add the ESN into their network and... well, it's just way too much hassle. AAA Keys, provisioning and such...
Sadly I don't think it'll work in Norway. I've seen ppl made the Evo to work for China Unicom (Only CDMA provider there) with a LOT, I mean A LOT of work just to get the 1xRTT functions such as voice calls and such to work. No data... YET because they haven't figured a way out to change the AAA key.
As for 4G/WiMax? Well, not going to happen unless your country decided to use that technology. Most likely LTE will be used instead of WiMax, knowing rest of the Europe relies on GSM systems more than CDMA.

..
okay'
Telenor norway provide cdma so what you are sayng is that this is possible for the operator to mix som up(even thou it is to muchtrouble..).. but then again there would bee problem for htc evo 4g because its not rim card replaceble?
this vpn thing in the phone.. what is that for? is that for the wimax only?

Well it's not, not replaceable per se, it's part of the phone. See in other countries where using RIM on CDMA phone is practiced, the ESN is part of the RIM card. Just like MSID on the SIM card for GSM (correct me if I'm wrong). Imagine it's a GSM phone but the SIM card is permanently part of it.
So what you have to do is ask your provide to ADD your phone's ESN onto their network so it can be used onto the system. However that only solves the 1xRTT (voice and text), in terms of data (EvDO), it'll be harder due to the AAA key and such. Your provider is the one that makes the final decision.
As for 4G/WiMax? Well I don't think there is any WiMax network rolled out in your country. Even if there are, it'll need further tinkering due to preset configuration in the phone's WiMax part.
VPN has nothing to do with WiMax. VPN is an application and WiMax is a protocol.
Anyway good luck trying to adding your Evo to your provider! It won't be easy but it's do-able.

hmm okay you sound like a really smart guy!
so for the phone to wokr I need the esn number and what more?
if you could just list what I need in that type of thing, if you understand me right
and maybe how I could find those thing. like how can I find the esn number in the phone.. I google it. I saw that its illegal to change the esn number so therefor it really hard to find a way to see it. but since Iam not gonna change annything + my htc evo 4g isent locked to any operator I guess i can do what ever i want?
thank you for responding I find your answers very helpfull!

imei and imsi
now I found something interesting that I wonder if it will work
I have a htc hero with a si card in it. And there I can see the imei number.
the htc evo 4g has a IMSI number.. Both looks the samme to me couldn't I just change IMSI number on the htc evo 4g with the IMEI number That it shows in my htc hero?
and then ofcourse add the esn number to my operator network.. wouldint everything works just fine then?

ATT 8528 on Verizon

Hi All,
I was wondering if I could use my unlocked 8525 with Verizon's net work if I switched to them? I'm not sure about compatability of the phone with Verizon's voice and data services and was wondering if anyone knew.
Thanks
I dont think so. Att and verizon use two different technologies. Att uses GSM and Verizon uses CDMA. Im almost certain tho a phone that is based on GSM cannot be used on a CDMA network. The phone will work on TMobile or USCellular. They use a GSM based technology. Verizon Sprint and Nextel all use CDMA. If i am wrong and you can use the GSM based phone with Verizon CDMA then someone please correct me. But i am pretty certain you cannot.
OK,thanks. Thats what I thought
Verizon does not have sim cards, is that correct?

Not that I've ever seen.
I know sprint phones have sim card slots, but they are not used, at least in the USA.
My guess is that CDMA phones can be used in the same way as GSM phones as far as switching sims to use different carriers, but the CDMA carriers in the 'states don't use that functionality (probably to keep a tighter grip on their sucke....customers and wring more money from them through phone sales/upgrades and extra services, like a data service to put on extra ring tones )
I know that I don't know much about these phones, but what of the setting inside of Settings/Personal/Phone/Band where you can select WCDMA as your network type? I've got an 8525 and it shows as an option, but I just don't know if anyone's tried it before.
CDMA and GSM phones are totally different. The only SIM based verizon phone that Ive seen its the Blackberry 8300 its world edition soo it can bu used through a cdma and also a GSM carrier. I would be interested if anyone knows how to say make a sprint phone capable of being on verizons network. That would be something different.
actually a sprint phone is capable of being used on verison network any cdma phone is. in short the way cdma works the subscriber info is assigned to the phone's esn by the carrier so only the carrier can change your phone with gsm the sim (Subscriber Identity Module) holds the subscriber info and it is assigned to a sim card id not a esn (electronic serial number) so all you have to do to get a sprint phone to work for verizon is get verizon to let it (GOOD LUCK WITH THAT) you would have better luck the other way around verizon is the pickiest co out there when it comes to network integrity and security issues they seem to think that letting people use any phone they want could somehow hurt their network

WCDMA is 3G. 3G on GSM systems is essentially a CDMA standard, but not the same CDMA as Verizon uses. It is not compatible.

Htc 8525

Does anyone know if an unlocked 8525 will work on Verizons network? I've been using it on Alltel and Verizon bought them out now they want me to get a new phone. Sure hate to give this one up.
If the sim unlock has been run the there should be no reason why not...
Mind you I'm in Australia...

CDMA vs GSM
I went back and forth on this one. (and Welcome!!!!!)
Verizon here in the states is a CDMA (EVDO) system that doesn't use sim cards, GSM systems does. This relates to how your phone communicates on the network. Now willl a GSM phone work on a CDMA network, i think that it will. The SIM card in GSM phones supply the network with your PIM to access the network, it is tied entirely to the network not the phone. CDMA requires action from the carrier, and your access to the network is tied to phone not the network. You deactivate one phone first, then activate the second. You'll probably need to supply your IMEI to verizon and they'll load your access. Just a guess though, cause I've been with cingular/at&t since i carried around backpack sized mobile phones.
Does anyone know better?
As far as I know of, no. I don't believe it has a radio for the CDMA. Although you state you have used it on Alltel which I thought was CDMA...
What reason did they give for wanting you to get a new phone?

[PREMOD] Modding Motorola Xoom Verizon for speaking HSPA+

I'm on the best way, here the facts:
1.) Crossflashing Xoom VZW with the System Image(Tiamat Kernel as boot) of European 3G Xoom is working fine after fastboot -w (complete wipe)
2.) With a firmware upgrade of Atirx 4G CDMA we saw, it is possible to reconfigure MDM6600 for GSM
3.) Simcardslot is working fine with GSM Simcards
Hi all,
Yesterday I got my Xoom. I'm how you see from Austria(Europe), but I ordered it from over the sea because I saw in a teardown, that there is a MDM6600 chip built in.
Now I have it, HSPA is not working, but should only be limited to CDMA by the firmware.
I would like to change that.
My first idea is, to search for MDM6600 driver sources, compile them for the tegra and replace the existing... but this expect, that the limitation is in the libril and not in the kernel...
Any thoughts to this topic?
edit: stupid me, first of all would be nice to take a look at etc
someone has an idea what the location.cfg is, and what the flag DL_LCS_NETWORK_3GPP (set to 0) are doing?
Kind Regards
Ralph

I have no idea how to help but I sure would like to. If there is anything I can do let me know I'm all set up to do all kinds of stuff I just would not know where to begin.
Sent from my Xoom using XDA App
Just 'cause the chip does both modulation schemes doesn't mean the appropriate antenna-interface hardware is built into the device. They put a 6600 in there 'cause they fully expected to push out a GSM version; I'd just wait for that one.
concerning the antennas(from www.motorola.com):
CDMA 800 /1900 LTE 700, Rx diversity in all bands
would be a bit funny, to use a multiband chip, to need not to produce different devices, but differ by the antennas
regards
Not to mention the fact that there is a place to stick a sim card in no the top of the device
Sim card slot is for the lte upgrade...
The SIM card is for LTE in the States, but again- just 'cause the chip is in there doesn't mean the US-spec Xoom has the requisite hardware (not to mention the proprietary Qualcomm modem SW) to let it run on GSM in the versions shipped in the states.
When we make GSM handsets at my clients, we even have to make separate hardware for the I, II, V-banded stuff (AT&T) vs. the I, II, IV-banded stuff (T-Mobile), and that's all with the same chipset.
You are going to need to take a good look at the NVM and amss.mbn(radio baseband image) in order to make this work.
Have you used RadioComm to read and dump the NVM?
That would be an excellent place to start. Unless of course, you had access to MDM6600 GSM radio images and source code...
I don't have even the slightest knowledge necessary to be able to contribute to this conversation but I do know that I am planning to go out the country for quite a while and would love to be able to connect to a wireless data service of any kind. I will be in a country with cdma also but of course it is not verizons.
If what you are trying to do works I would happily try to donate something out of appreciation. The idea of my xoom working with gsm networks would be more than a dream come true. I wish you all the best. Let me know if there is anything I can do (I know there isn't though, I really dont know the first thing about modding other than that the modders are awesome!)

Good Morning,
There is something confusing me, and it seems I've to think about something I cannot imagine actually.
So my big stupid question:
Do you need a simcard to connect to verizon's cdma network?
And if not, how are you athentificating in the net?
Regards
Ralph
CDMA authenticates to its network via the combination of the MEID (formerly known as "ESN") and the MIN, both of which are hardwired into the firmware of the device.
Ok, so the device is authentificating, but from where do the network know that you are user xyz? In gsm networks because of the simcard id, and in cdma nets?
Sent from my Xoom using XDA App
They associate the MEID/MID/MIN to your account.
For example, they scanned the barcode from my Xoom when I bought it and added it to the Verizon account they had already finished setting up for me. Once I got it home and hit the "Activate Device" button, the device got on the VZ network, where the setup information (the phone number, PRL, etc.) got downloaded to the CDMA 3G radio. But all that happened 'cause the VZ servers were already set up to associate that MEID to me beforehand.
ouch, that means there is a massive firmwaremod needed so that it can use the simcardslot for auth...
ok, please tell me what you know about how transfering the data from the sim to the chip works (bookmarks and so on)
do the ril-daemon play a role?
thanks

Now no sim card is used to connect to Verizon's 3G network. The new 4G Lte network will use a sim card, but that has yet to be activated. At present you connect to Verizon's 3g network through the cdma radio which needs to be registered and then activated by them, but it does not use a sim card.
Sent from my Xoom using XDA Premium App
The sim card slot is a dummy slot right now, there are no electronics in there that can even read a sim card right now. When you send out the Xoom for the LTE upgrade they will put a real modem in there with the sim card slot. It is PHYSICALLY IMPOSSIBLE to convert the Verizon Xoom to GSM at this point in time.

Key words: "...at this point in time."
That may change once the hardware is in place for the SIM slot it MAY be possible to build a radio image that can access GSM/HSPA bands.
Not easy, but not impossible.

You would also need to modify the antenna to pick up the correct frequencies, they usually aren't on the same band as CDMA. For example VZW is the only carrier going for a total 700mhz 4G network.

That's almost correct. There's a working, active SIM-card slot that's hooked up to a serial port on the CPU; reading a SIM card right now would just be a matter of some (extra?) software. What's physically missing is the actual LTE modem, and there's a dummy card in the mini-PCI slot right now.
But that's not why it's not possible to turn the current device into GSM; as noted in this thread before, there's a lot of other things that'd need to be there, and just 'cause the 6600 is GSM-capable doesn't mean it's a simple, software-only modification. Even if it were, good luck getting the customized baseband software from QCT for it.

[Q] Bad Network On Android Phones

Hi guys and girls,
Today, i'm writing my first post on this wonderfull forum. I have a problem.
I have very bad network sensivity on every Android phone i have. I'm kinda new to android but i know at least a minimum.
The questions:
If i buy a phone in a country and then take it to another country, can it lead to bad network?
Can the baseband version of a phone be good in one country and bad in another?
Are the OTA updates specific to a country (scandinavian android updated in a non scandinavian country) or are they different from a country to another?
The actual situation:
I live in Belgium but i'm norwegian and i'm used to Norwegian keyboards with Æ, Ø, Å characters) so I have bought my a SE Xperia X10 Mini Pro in Norway, but i think after i did the 2.1 update in Belgium i got bad network. Now i got a HTC Desire Z also bought in Norway and had perfect network in norway, i updated to the 1.72 still in norway and still had perfect network. Then i came back in belgium and had bad network. Then i updated to 1.82 and then to 2.42 (the gingerbread version 2.3.3) and i still have thebad network problems in Belgium. The rom is still the scandinavian/nordic and i was wondering if there is a different baseband version in the ota update from norway and the one from belgium eventhough its still the scandinavian sense rom.
If this is the answer to my problem.
Since i'm on a gingerbread Desire Z, how can i change the baseband version?
I guess i'll have to root, Is there a easy way to root a GB DZ?
Info:
Android: 2.3.3
Baseband version 12.56.60.25U_26.10.04.03_m
Kernel: 2.6.35.10-g7b95729
Software number 2.42.405.2
If you need more info or anything, just ask me. I really want to solve my problem and help others maybe find an answer to theirs.
Thanks in advance,
Bendik
Anybody? Please?
I really need help on this one.
define "bad network" are you sure the carriers in each country use the same bands? Radio loads and RILs will make all the difference. Have you tried locking to 2G?
Well, by saying bad network i mean i have between 0 and 3 bars most of the time. Even with nice weather.
I have no idea if my countries carriers use the same bands. But what i discovered was that if i use my norwegian sim card in belgium (roaming or something) and i use Mobistar (another network carrier) then i have 4 bars allways. I couldn't try to roam on base (my actual carrier) or proximus (wich is the lands monopol carrier).
The thing about radio loads and RIL's i didnt understand anything.
And locking in 2G doesn't change anything.
There are three carriers in belgium: Base (my actual carrier), mobistar, and Proximus (the countrys main carrier)
I ordered free SIM cards from the other belgian carriers.
I got one from mobistar and it worked perfectly.
I haven't tried proximus yet.
Base is the one i have problems with.
So no i have another question: Is there any differences between sim cards from one carrier to another one? Except that they dont allow me to connect to other carriers than the card carrier?
I know i may be spamming a little bit but this is kinda important to me.
So please, if anyone could give answers or help me i would be thankfull.
I think that not all carriers have the same signal strength in a specific location .
In my country there is three mobile networks and in my home they are not equal in signal strength .
one with zero signal , the second with moderate signal and the last one with perfect signal even though they are equal in the street which is 10 meters away from home !!!
You said that mobistar works perfectly so maybe you should stick with them and ignore the one you use right now .
Thanks for answering me.
I really liked base because i had so really cheap bills. Instead of paying 25€ for free texts and ringing and some internet im paying 10€ with my actual one.
I mailed base in case they could help me, and after about 2 weeks i finally got an answer. Theyre working on it...
Maybe it is the 3g band. Look, here in my city, if I use 2g, it works OK but in some areas i have no signal. If I turn on the 3G, I have a very good signal in almost every corner of the city. Verifiy that.
Hello,
-The easiest way might be to contact your actual operator, they should check the 2G/3G coverage in your area. But i guess you can do this yourself, somewhere on their website they should have a map with their signal strenght.
-Change your mobile phone; try the sim card in a different phone. Does it get the same signal strenght? - With this you will determine if the problem is in your mobile phone. If you get better signal in a different phone, you may have a broken anthena in your device or you've messed up something in the settings.
-Ask someone around you with your carrier what strenght does he get. If it is higher than yours and you got the same strenght in more than one phone you may have a wrong sim card. The carrier should change it for you.
Check this and let me know the result I'll try to help.

I am very interested to find out what Base does as I am in a similar situation to you though I bought my Xperia 10 mini pro here in Belgium.
When I use my Base sim card I have problems with the signal on either of the tree network settings.
When I use my Slovenian one, I don't have any problems roaming on Base, Mobistar or Proximus.
I always get a good signal when I use my Base card in a different phone though.
Sounds like the frequency for me! Check the frequency of the 3G band for your 3 operators and then check if your cell phones can handle that.
I saw that Mobistar (/the only carrier i get good network on has another band if i understood right)
Im still contacting my actual operator about the issue and they will need another 2 weeks before they can answer me... Of course...
SIM Card in another phone, in a 2G phone SE k550 i have full network. When i lock to 2G on my Android phone, it still has sucky network.
I have a friend (OMG) on the same carrier i had network problems with. he has allways full network, i'll try to see if i can make him come over and test the network with his android phone (acer liquid metal or something)
Ok, let us know how that goes
yes,you may lead to bad network.but the chances are little
Are you on 3g only?
In belgium, Proximus and Mobistar have the best networks.
Base has 97%coverage of edge, but their 3g network sucks.
Are you certain that its everywhere in belgium that base has a bad reception?
I contacted my operator, they told me to try to lock to 2G, i tried it for an hour and still no succes. I restarted my phone after i locked to 2G juste to be sure. Still no success.
I've allready tried in another phone, in my old SE k550 i have full network allmost all the time. I've had the same problem in my x10 mini pro even after a fresh original reset. I really dont think its the phone since i have perfect network when i'm on Mobistar (another carrier that is expensive).
I have a friend that has an Acer Liquid Metal (?) and i'll try to make him come over to test his network.
I have allready changed sim card but they made me pay 10€ for that... --'
Now i'm waiting about a week for another answer from my carrier.
I hope they can do something.
I have bad network everywhere except in the subway (underground :O )
I have this bad network with Proximus and BASE.
I'm was in auto HDSPA/GSM and than tried the 2G only, and now back to auto.
When i'm in auto, i think i noticed that in the moments i have Edge i tend to get better network. But when i lock to edge/2G i still have bad network...
I tried again to lock 2G and it works with full network. Still contacting the operator.
From a quick search of the internet it appears all the providers listed use the same frequencies, 2100 for 3G & 900,1800 for 2G.
As well as selecting 2G only I would also select the mobile operator manually, instead of automatically which I believe is the default. It is also a possibility that the Android phones sold locally have a different radio version then yours that works better on the Base network, I've run into this in the past with Windows Mobile on HTC phones.

GSM/CDMA radio question

I have a question about how GSM and CDMA radios work. I have an HTC Merge from USCC (I live in Vermont, USA). They use CDMA and leave the SIM unlocked for prepaid SIM cards. I travel to Alberta, Canada on a regular basis and have access to a post-paid account on Bell Mobility (GSM). I would like to figure out if it is possible to set up my phone to work on both lines at the same time, without having to switch back and forth to check for incoming calls and texts.
Is such a setup possible?
If it is, does anyone know how I would go about getting it set up (perhaps a different thread for the answer to this part)?
On a CDMA phone, where is the carrier information stored (phone number, PRL, etc.)?
The phone is currently rooted, S-OFF, SuperCID, SIM Unlocked, running 2fastrom's USCC Gingerbread ROM.
Radio version is 1.08.00.0804
I am posting this here because I consider it to be first of all a question of whether it is possible to use both systems at the same time, regardless of the phone itself. I have added the phone info in case those who may know the answer need it. If it needs to be moved, I have no problem with that.
Thanks for your time and consideration.
All the best,
Reuben

I know the iPhone 4s can use both but it has two separate antennas to accomplish this. I think it comes down to hardware.
Isn't Verizon coming up with some type of solution with VMWare for this? Where you could have two numbers active at the same time, one of them being a business number that was running in VMWare?
Yes, it is partly a matter of hardware - the Merge is set up for both systems. Still not sure if it can "listen" for two different numbers at once. Also curious about whether the phone needs to be listening to both bands at the same time if one number is CDMA based and the other is SIM/GSM based.
Verizon's solution sounds interesting - not sure it is enough to make me switch, particularly if both numbers have to be on their network.
Yes but only if you are not Verizon.
http://www.pcworld.com/businesscenter/article/247646/lg_verizon_and_vmware_demo_virtual_work_phone.html
Currently Telefonica will support 2 simultaneous numbers due to a dual-sim. I really can't wait until entire networks start switching to an all IP based system. This would allow a much more flexible system then the NAM currently used.

It will eventually coming , we may see this type of services in near future once iphone will start shipping with GSM and CDMA unlocked version.
No its not doable at the same time
