Hi, I would really like some help picking out a new unlocked dual sim phone. I will be traveling around the world consistently and need to be able to jump on some kind of GSM service in X country. I'd also like to keep my USA based sim card in my phone as well....just in case someone back home needs to get a hold of me. And lastly, I need a phone with decent hardware specs.
So what phone would you suggest? I don't mind if the phone isn't factory unlocked...I've unlocked my Evo, Evo 4g, and Evo 4g LTE phones in the past just fine with the tutorials.
I'd really like something that isn't garbage. I keep seeing these Blu phones, but they are like $100 and seem a bit lackluster on hardware.
Is there a GSM based flagship phone out now that I can simply install a dual sim adapter into, and acquire my desired results?
Just curious what people smarter than I in the phone arena would do in my situation.
I'm using thé HTC zone m7 dual sim and it's work perfectly for me. I' m living un africa
I have same situation as you, but I am not able to find such a phone. There are dual sim flagship phone selling in Asia, however it does not support all bands in US. I may buy the new Windows phone Lumia 950XL from MS store(not from at&t because ATT version is single SIM, but MS store unlocked version is dual-SIM).

Looking at pictures of the Rezound, it looked as if it has sim card support, is there any known way to root/unlock the phone to use on T-mobile/AT&T?? if so i need one...
no the sim card is for LTE only. Sorry! It doesn't have GSM or HSPA support. Only CDMA EvDo 1xRTT and LTE
Ah bummer. Well ill definently have to consider virizon instead of tmobile when i get my own contract

Excuse my ignorance, but just trying to sort this out. Realise it uses an LTE sim card, but as I live in China was hoping to put in a china telecom sim card and use it on their CDMA2000 network (which it does support).
This possible? Thanks in advance.
The sim card is solely for LTE if that helps. It may be possible to flash it to their network but I cannot answer a yes or no
It depends on the spectrum your LTE network uses. The phone should function CDMA only if you or your carrier know how to flash it correctly. Verizon uses a special LTE spectrum range they bought from the FCC known as C-Class if I remember correctly. It was sold after the US went from Analog to Digital TV. There were A-E Class Spectrum and C apparently was the best for whatever reason. I don't know to say anyone on here would know any more info than that in regards to the frequencies.
Thanks, I don't know how to flash it and I assume my carrier probably doesn't know how to or want to either. Shame. Really wanted this phone. It is being sold on taobao here (Chinese ebay equivalent) so maybe a solution will be found in the future.
There is a program called CDMA Workshop that most places in the US use to flash CDMA phones from major carriers to pre-paid carriers. I am sure someone over there could do the same. I lived in South Korea for 2 years, the stuff they could do was ridiculous, and I know China is the same. Actually, my neighbor is from China and is pretty tech Savvy too. I will text him later as he was just in China a couple weeks ago.
He said his girlfriend was able to bring her iPhone from China and have it flashed. Should work the other way around. As far as LTE though, beyond me.
If the qualdcom processor on the EVO is ment to support LTE which in turn uses a sim card shouldn't that make the phone a world phone I know it is suppose to have an embeded sim. But my true question is will we be able to reporgram the sim once we get root or will write have to go with more of a hardware mod if we wish to make it a world phone.

Sprint uses embedded LTE technology to my knowledge, so its not like on Verizon where there is an LTE sim card. Also, this phone is a CDMA phone, and therefore does not have a regular sim card slot (Like phones on ATT or TMo). No software modifications will change this, and I highly doubt that anyone could even attempt to make a hardware modification to make this phone a world phone. Also, and LTE sim card is not the same as a regular sim card, as they perform different actions (access to LTE and the rest of the network is seperate).
Yeah I was thinking that it does not have the slot the thing is that the processor does support gsm also I was kinda hopeing it was like the rezound it is cdma phone on Verizon. It was found out that just by removing verizons LTE sim card and adding a gsm one it allowed the phone to work as a gsm phone.
the evo lte does not have the GSM and HSPA+ radios to be a world phone
When I preordered, the rep told me it was a world phone. I didn't think she was right but I didn't say anything.
Yeah i read the same post on Engadget i think. What a bummer was hopping it was since it is rocking the same processor that the at&t one (correct me if im wrong). Plus like i also stated was hopping it was like the HTC rezound on Verizon that with a experiment it ended up working. O well .... still kinda wanna take it apart and try wouldn't be xda without some experimenting or moding.
My friend has a Droid bionic which wasn't supposed to have GSM support, but it did through some hacks on rootzwiki and using a T-Mobile sim card. I think that the s4 includes a GSM radio, so its probably possible at least if the sim card can be accessed. Lte is GSM based so it is likely that GSM support is there if software is modified like it was on the bionic.

Sure, you can use it anywhere in the world that has a compatible CDMA network.
Many identify world phone with GSM radios (which the Evo 4G LTE does not have), but CDMA (which it does have) does work well for roaming in Asia.
I've roamed with my Evo 4G across Japan, Korea, and China for both voice and data. There's a full list of countries with CDMA roaming on the Sprint website. As soon as you arrive in country (if roaming works), you receive a free text with the rates and instructions on how to make international calls.
According to the sales assistant in my local Phones4U shop, there are 2 different versions of the 920, one that won't and can never work on 4G and one that will.
Does anyone know if this is true? I assumed it was the device that was 4G capable, full stop. If you have a 4G network/SIM then you put it in and it works, possibly requiring some change in config settings, but surely there isn't a 3G only version of the device.
They wouldn't sell me one SIM free as they only had enough stock for new contracts apparently and it was only available in white so far. Plus, this is where she then claimed that I had to buy the EE contract version in order to get a 4G capable device, and my theory of buying a SIM free device to use with my SIM on the 3 network for now, with a view to gaining 4G once 3 brought theirs online in my area.
Appreciate any comments from someone who knows what is true. I really don't (want to) believe what the sales assistant has told me. It seems daft.
cheers,
Wes
All of them are capable of LTE, but there are variations in the bands, so it is possible that you could get one that wouldn't work 3's LTE once it is deployed, but that is very unlikely if you purchase a UK version of the device as I'm fairly certain OFCOM didn't sell too many bands for LTE.
I got told the same thing at P4U
I was told that my Black 920 EE branded wouldn't work on 4G but if you look on the box all the LTE bands are listed... turned the phone on and found a option that allows 4g connection... i will find out in a few days once my EE 4G sim turns up.
called up the local EE shop who did me a black 920 for £399 and gave me a free set of WESC headphones and a free wireless charging plate, there and then. Oh, and i also had to pay £10 top up for a PAYG SIM that came with it as this was a deal for buying the phone as PAYG. It accepts EE, Orange, T-Mobile and Virgin SIMs in the UK so i can just put my existing Orange SIM in. Absolute bargain i thought
Long story short..... Due to some crazy crap my company has decided to pull I may be moving to Costa Rica for a year or traveling back and forth multiple times a year.
I am going to want to keep my US phone number and cell phone plan and also get a phone number on a plan with the local carrier Kolbi in Costa Rica. I currently have Verizon and their international plans are awful and ridiculously expensive. Only US carrier with free international roaming is T-Mobile.
I want to buy a dual sim phone but it seems like there are no options since I am currently with Verizon. Best case is I would like to keep Verizon due to good service in the US and find a dual sim phone that supports them... Worst case is I get a dual sim phone and switch to a US carrier that it will work with most likely TMobile.
So main questions...
Any good dual sim phones that are compatible with Verizon?
If no to above what phone and carrier should I switch to?

Hi guys,
I rooted the phone, installed audio and viper mod... but the only reason I even got that far was trying to root the phone to get additional bands added to the modem. Seems like I am not getting far lol.
The ulefone power 3s I got does not work in canada for bell... as it lacks 3g apparently and only has 2g and 4g? 4g data works, calling phone with 2g works. So data works for bell mobility and rogers, but voice and sms does not work with bell mobility... only with rogers/fido/koodo.
I am going to switch to rogers from bell due to better cost (45 a month plan with data) vs 80+ with bell... so ill get voice working but im worried then how much this phone will work when roaming in the states and what have you....
I seem to be only able to find how to edit bands with qualcom based phones but ours is a p23 or mtk 6763 processor phone.
Did you figure this out?
Just wondering if you were ever able to unlock the bands. I am having a similar issue
Fault of the smartphone made in mediatek：
The japan domestic carrier company where iPhone is set to use all of carrier bands in Japan merely hangs SIM lock and sells a terminal, but even which carrier is available if I cancel it.
However, there is no human being who wants to use this even if the phone which is how much which is the phone which is usable only in Japanese Tokyo where only a measure band of 3G and the LTE is usable because it is sold domestically without most of the carrier bands in Japan being available is bargain as for the smartphone made in mediatek
Even if the person buying it appears if baseband sets it freely and can add it, such an application does not exist.
Because I get the root right, in z3c of sony where band addition is possible freely by QPST and QXDM if it is a phone of snapdragon, there are still many users
The smartphone made in mediatek is a really useless (not smart) phone in Japan
