Is the EVO network locked? Can i use for CDMA in other country?

hi All!
I am in a big fix and need the right facts here... so please help if you know of it, and are sure about it.
I intend to buy the HTC Evo 4G outright from Sprint, from the HTC US online store, for around $549. Now would like to know if this would be network unlocked?
I need to use this phone in India on CDMA network of the same frequency as the Sprint's, and i know i can use it here without a sim card. Now my only worry is that whether this would be locked to only Sprint network when i pay the full price for it from HTC store?
Thanks a lot!

Without rooting and some modifications, it is locked to the Sprint network. However, if you poke around some of the other forums where people have unlocked CDMA phones (the CDMA Hero comes to mind) you might see what they've done to unlock it to other networks.

I know this is very old post, but help me too. I want to use my htc evo in korea. It is rooted with s-off and I'm wondering if the phone is country locked or locked to sprint network. How can I tell? thx.

You can't unlock a CDMA phone, only GSM can be network unlocked. You can use your Sprint phone only if Sprint has set up an agreement with the country you are going to. But then you'd have to pay Sprint International Roaming rate.
According to this,
http://internationalroaming.sprint.com/IntlCoverage/SearchCountry.do?ECID=vanity:sww
South Korea is listed.

You can if you can do the following:
1. Have a way to activate the EVO in S. Korea with a provider that runs CDMA in 800mhz (create account, and add the EVO's ESN to that account)
2. Have access to a PRL file that gives priority to the CDMA network by the provider in #1, and update the PRL on your EVO with it.
I think #2 is doable, #1 may be difficult unless you know Korean well, or know someone who understands the issues and is willing to help. Also, while Korea has "PCS" bands, but they are not the same as the 1900 mhz PCS bands in the US, I believe they are in the 1700 mhz range, and are not the same as the AWS bands in the US, also in 1700mhz, but also in 2100mhz.
All that maybe fruitless, as you'll only have voice call capability, unless you also know how to program the mobile ip settings to get data working as well.

[Q] do I need to flash my radio to use TP2 abroad?

Hi there,
I'm totally confused as to what I need to do to get my Touch Pro 2 (currently activated on Boost CDMA) to work abroad, specifically Canada.
It is flashed with Energy ROM, Reference version.
Do I need to do a Radio flash? Do I need to tweak some settings? Both? Neither?
I'm going to be in Canada for 3 weeks and plan to use either Rogers or Fido's GSM Pay as You Go (already have the SIM cards), or Telus's CDMA Pay as You Go.
I've read the FAQs and generally understand that this is possible -- just not clear the route.
Thanks,
Simmy

The biggest problem with Canada is our carriers don't want people coming in and using their networks without paying for it, and that usually means your first born here.
The hardware problem is, the TP2 will not work on the frequencies in Canada that Telus has used for the HSPA / 4G network. And using the current CDMA network is not possible either because Telus and Bell will not allow you to put branded phones from other companies on the old network and CDMA systems don't use SIM cards. So if your planning on bringing the TP2 up here I think you may be out of luck.
I took the TP2 to Ireland and was able to use the frequencies there on the O2 network, but to do that I had to unlock the phone and as i have the "world edition" with the SIM card slot once unlocked it worked over there no issue, and returned working over here with no SIM card in it. But again this is a frequency issue and telus tells us it won't work.
Now if when you get here, and you plug a sim card in and it does work, please share, because it means we can manually add frequencies and hook to both the old and new network. And some of us with the original unlimited data contracts (no 10 gig cap) would be really happy to know this.
As for Rogers, i can't tell you. I don't know if they have ever had the TP2 and have no clue what frequency they are using for their phones, though i'm sure it's similar.

Flashing the radio does nothing to add radios or affect your ability to connect to the network while abroad. Its usually just done to improve reception and/or battery life.
You will need your phone SIM unlocked. Then, as the post above suggests, either putting in the SIM works, or it doesn't.

Thanks to both of you for your reply.
So the TP2 won't work on any Canadian CDMA networks, but since it also has GSM, if I stick a Rogers or Fido SIM card in it, it *may* work. In fact, I believe it *should* work. I'll let you guys know how it goes.
And thanks for answering my question re: radio ROMs, Redpoint -- that's what I thought, but was still confused about.
So, with respect to unlocking, is the Olipro page that charges 11 pounds / 14 euros / $20 my best/cheapest option? (unfortunately, i can't link to it here because I'm a new member)
Thank muchly,
Simmy

The device should have no trouble connecting to a normal GSM network in Canada. The Canadian GSM networks use the GSM-1900 and GSM-850 bands. The CDMA Rhodiums use a quad band frequency that spans all of 850/900/1800/1900 MHz channels. You should have no problems in Canada. Enjoy your trip.
You do not need to flash a new radio to have it work in Canada.

I heard that the Thunderbolt can't do this so I doubt it.

The Thunderbolt isn't a world phone, which is why you can't do it on the Thunderbolt.
Have you tried putting in a different SIM card? I haven't tried that, but if you switch to a GSM carrier, there should be a way to turn off CDMA roaming and enable the GSM options, that appear to be grey-ed out for some reason...

Called Verizon Global Support a few days ago and had them give me the SIM unlock code. Once unlocked I was able to insert a T-Mobile SIM card. I went to Settings>Call>Preferred Network and changed to GSM. I was able to make/receive phone calls on the T-Mobile network as well as connect to the Edge data service. I did however have to add the APN setting for T-Moble (epc.tmobile.com) to get Edge service.

I got the I2 a week ago and 2 times I have unlocked the screen to see a dialog box saying I have lost my data connection and prompted me to choose between CDMA and GSM modes. I haven't tried to switch modes, but it worries me that I am losing the data connection.

Even though the data is just Edge, it works on T-Mobile in the U.S.? Interesting. The only other global Android devices on Verizon so far - the Droid Pro and the Droid 2 Global - have T-Mobile and AT&T bands completely locked out. I wonder if it would work on AT&T as well.

Yah it works quite well you have to manually change the apns in the GSM settings. I did find the switch to change calling modes between GSM and cdma it's under settings ->call settings

If it's not switching over on its own, try the test mode - *#*#4636#*#* and then in there you can choose GSM (PRL) or WCDMA preferred, both of which switch you onto GSM or 3G GSM respectively.

Did anybory try?

Did anybory try this? Is 3G works on Inc2?
By the way:
Inc2 supports:
CDMA 800/1900MHz +
UMTS/HSPA 900/2100MHz +
GSM/GPRS/EDGE 850/900/1800/1900MHz
And some info from t-mobile forum:
Mobile USA's frequency is the AWS 1700/2100 band also known as UMTS1700. Europe's band is 900/2100, also known as UMTS2100. The phone must be able to connect to uplink and downlink for it to be compatible on a network. Since his Nokia was UMTS2100 it could not connect to T-Mobile's 1700mhz uplink frequency.

3g works in the uk. No idea about T-Mobile

How they gave your unlock code - did you by phone by _retail price_?

Does anyone know if it would be possible to only have T-Mobile US SIM handle only the calls & texts part, and Verizon data with the Pre-Paid $30. unlimited data?

You call Verizon. They verify that you've been a customer in good standing for 6 months or more, and they give you the unlock code. No charge. You can't unlock more than one phone per account per some period (13 months, or something like that). It doesn't matter if you have a contract term, etc. (you don't need to pay full retail for the phone).
Once you're unlocked, you can use a SIM from whatever carrier you choose. There have been reports that you can't use others in the US (AT&T, T-Mobile), but I've not tried that. I've had no troubles using a Cingular SIM in Europe.

Oops from my Incredible 2 using xda premium

does this method work for a us cellular customer? i have the electrify and plan to travel later this year. the whole idea for the world phone was to have it work there as well without the god awful international roaming.
i just use the *#*#4636#*#* code and put it in gsm/cmda auto? then how do i get it to recognize the sim when i get there?
i am using cm7

which an unlock code ( from Verizon - U have to unlock the first time ), Inc 2 can use GMS network ( both GPRS, Edge, 3G - HSDPA 900 / 2100 )
I'm using an unlocked inc 2 in Vietnam, with GSM network. It work well, both 3G and GPRS
PS : Using stock rom ( 2.3.3 ), AOKP and some other rom ICS doesn't work ( may be a part like sms doesn't work ).

FYI - being a VZW customer in good standing, I called up - using another phone line - Global Support & requested Sim unlocking, after verifying my identity - reading the disclaimer/emailing the disclosure docs, etc. & placing me on hold for a short while, came back & gave step-by-step instructions on inputting the 8 digit unlock code into the DI2 - the phone's screen displaying "unlocked" (it's good for life) then powered down & rebooted, and it was good to go.
I replaced the stock Vodafone SIM (note: it's not provisioned or activated) with an active China Mobile Sim card (that I normally used with an unlocked quad-band LG or Sony Ericsson "feature" phone) - turned off roaming data & mobile data access before switching over to GSM mode, and, it's success & ready - registered on AT&T's 3G network (CMCC's roaming partner, also with T-Mobile.)
I was able to send short codes to obtain my CM account balance, etc. (*#130# - Send for my overseas carrier)
Just returned from a weekend cruise to Bermuda (UK) trip and it registered with DigiCel for roaming on the island with GSM active only - (CellularOne is also available for roaming purposes) These are the same carrier for AT&T and T-Mobile Sims when going to this 21 miles island out in the Atlantic.
While on the cruise ship (Royal Caribbean) - it registered with their satellite based ship services for voice/SMS and GPRS (yes, it's slow 2G) services in GSM mode (it also worked in CDMA mode - beware of expensive Mobile Data pricing & per minutes calling rates ...)
FYI - back here on USA mainland now, prepaid AT&T Gophone & T-Mobile Sim cards worked on this unlocked DI2 (Edge/2G data only plus Voice/SMS) - it's easy to change APN settings to match AT&T or T-Mo if the account is provisioned for it - using both SkyRaider's custom ROM and Nijitsu's Sense ROM here.

LG G2 for Sprint gets no love of GSM unlocks

Hello,
So I currently have a Sprint LG G2 that I would like to unlock to be able to use it on AT&T or Tmobile. From what I'v read, even the Verizon G2 comes factory unlocked which Verizon's been known to keep locked in almost all of there phones. I called customer service and told them i would be traveling overseas (they didnt ask what country) and after about 24 hours emailed me asking permission to unlock the device, they told me to go and update me UICC Unlock which gave me a message saying "your SIM is now unlocked" but when I put in a Tmobile sim card to test it, the phone would not recognize it no matter if i changed the settings to gsm/umts or global mode. What do you suggest I do next, I am worried I payed so much for the phone and if 1 or 2 years from now I decide to move carriers or even country that I am visiting to next week and the phone bieng "unlocked" still wont unlock it to be used on local carriers or even abroad, that would really suck. Any suggestions?

You really need to do some serious research.
Concerning Verizon, Verizon is required to have the GSM portion of their CDMA/LTE phones factory unlocked due to to a requirement by the FCC when they divested some spectrum a while back.
Now for Sprint, Sprint locks down (or locks out) the GSM portion of their LTE phones for domestic GSM use, so trying to use it with a domestic GSM carrier like AT&T, T-Mobile etc is out of the question by default. They'll unlock it for international GSM use (non U.S GSM carriers). Now there are some fine folks on XDA here that have been able to work around these restrictions on the Galaxy S4, but that's the exception so far.
If like you say, they emailed you that they've unlocked your phone, if you leave the country and insert a foreign SIM, it'll work with that international carrier.

Your right
your absolutly right. Now i need to find out how they did it in s4 because it has to be possible for this phone too then that case

Hmmm, this is interesting, I am having a similar dilema, as far as I was aware, I thought that unlocking would be done on the cosumer end, they would give you a code, then you'd input that code in, I've just never heard of them unlocking it on their own. I got the LG G2 LS980 when I was in the US for a semester and moved to Brazil just a week ago, I haven't tried to fully make it work, but from the LS980 manual, it says that there is not even a sim lock on the phone(i'd put up a picture, but I have no idea how). And when I try to put in an old local(brazilian) SIM card, it doesn't ask for a unlock code, it just says no SIM card - Emergency calls only. I'm still researching it, but if you find anything, just post it here so I can keep up Thanks.

Yeah I will definitely have to wait for a workaround for the sprint LG G2 as I am not a sprint customer. I think the S4 and the HTC both have workarounds, but as far as I'm aware, these workarounds apply mostly for international use only (which is exactly what I need) meaning that ATT/TMOB is probably not going to work, or might have to wait a couple months until there is a lot more people working on the sprint version, the thing is, the phone wasn't released that long ago, so support in the forums is still low.

Back during the photon days they were able to achieve domestic gsm use by flashing the radio from the Japanese version of the photon. Well maybe not directly. It may have been a modified Japanese radio but it worked!! My daughters mother still uses the photon 4g as an att go phone. Would something like that still be possible for our devices? I know a lot of people lost interest in it because after the photon we got the photon q which had an embedded Sim. Even then people were able to take the phone apart and solder a Sim tray in and unlock it for other domestic carriers.

As long as some foreign carrier has their g2 unlocked for international gsm use then it wouldn't matter right? With the KDDI radio on the photon we weren't able to use sprint service on it after flashing. Basically as if the phone thought it was the Japanese version of the photon.

This would be awesome if it worked, I'm still hopeful someone will find a way, because I don't use sprint anymore and I have since moved to brazil. Thank god this phone is awesome enough to not be useless with only wifi, but I'm still hopeful someone will find a way for me to catch Brazil's GSM signal, as the phone does have the right GSM bands for it.

Just like the HTC one, it took months for even Sprint themselves to figure out how they would unlock the HTC, what I want to know if there is anyone that has actually called Sprint and asked for the unlock, and confirmed it to be working.

Can the sprint lg g2 be unlocked for any carrier.
Im trying to change from sprint contract to straighttalk. Is there a way to get my LG G2 unlocked so I can switch?

I unlocked my GS2 Skyrocket recently as I'm about to sell it and pick up a G2 next week. I popped in a T-Mobile SIM and verified that it worked. However, I very seriously doubt the method I used would work on the G2. Here's the thread though:

I called the Sprint international department and they explained the situation somewhat.
Domestic sim cards such as on tmobile and att have too little memory to support the cdma function of the lg g2, so you will get an "invalid sim" message. The size of the sim must be at least 128k to work on the g2. Maybe there is a way to get domestic network data on a larger sim card.
Hope this helps.

while the size thing may be true.. this is not why youre getting an invalid sim error. the invalid sim error comes from when u use ANY sim thats not Sprint. After you get Sprint to OTA SIM unlock your phone.. this invalid sim error goes away... gsm will work for intl.. and possibly domestic.. tho sprint may also have a block on domestic only.. after the intl unlock. if the phone is unlocked thru sprint and you pop a tmo sim in and get no signal(but no invalid sim error)... then that means the phone is unlocked properly but domestic is blocked.
this is usually my area of interest.. i did both the htc one and gs4 unlocks but I do not own a g2 unfortunately.

So are you saying if you did have a Sprint G2 you would be able to find a way to unlock it?

How the heck do they do this?
How can they unlock the phone for international SIMs and prevent them from working on local SIMs? Can't be some band that they check. Otherwise, it would not work on an international SIM using that band. Hardcode something in the kernel or the OS? In which would a custom ROM and/or kernel work? Can anyone point me to some links or posts that discuss this?

I'm also interested in this as I have a LS980 and I am currently in Brazil, sprint has done nothing yet as far as unlocking it.(even for actualy customers, I have not seen anyone that actually has this thing unlocked). I popped in a Claro(local provider) SIM card, and the phone says "No SIM card- Emergency calls only", I've tried multiple SIMs to see if it was a problem with the actual SIM, but all of them read the same thing, while inside the phone I get a notification saying "Restricted Access Changed - Voice Service is Blocked". So it knows there is a SIM card in there, it's just blocking it.

LG G710EAW on T-Mobile. Crossflash?

Hello all!
I have an LG G7 from India, model G710EAW. I moved to the US from Canada and the phone isn't entertaining T-Mobile or ATT SIM cards. When I insert them, service works for a little bit and then immediately switches to "Emergency calls only". T-Mobile's website says my phone IMEI is compatible with its service.
The strange thing is that the phone has two SIMs from Canada roaming - one on the T-Mobile network and another on ATT. No issues whatsoever. And when I check the bands in Engineering Mode, I can see one roaming SIM running on LTE Band-4 on T-Mobile. The other roaming SIM is switching between LTE Band-2 and LTE Band-5 on ATT.
T-Mobile uses bands 2,4,5 mainly, and ATT uses 2,4,5 among other bands.This leads me to believe it's some kind of a network restriction preventing my phone from latching onto these networks directly.
I've made tons of calls to T-Mobile and ATT so I'm no longer interested in pursuing them with this.
I'm wondering if cross-flashing a different firmware might help fix this issue. I remember reading on this subreddit that the Google FI firmware may work for T-Mobile bands. I'm not sure I understood that correctly.
Can someone confirm if that's possible? Does this make sense? I'm hesitant to buy a new replacement phone when my G7 works so well.
Thanks!
