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).
I have looked all over for a dual sim phone that will allow both sims to connect using 3G or 4G at the same time.
Does such a phone exist?
There are many dual sim phones that look quite nice, such as the LG G4 or OnePlus 2, but it appears they all allow only one sim to use 3G/4G while the other has to use 2G
This seems like a ridiculous restriction since 2G is no longer supported by many carriers and soon won't be supported by any carriers in some countries. Surely there are dual sim phones which allow two 4G connections? Or even 3G+4G.
Are those places (sites) that you pay to unlock your phone legit? Is it possible to unlock the Verizon version of the G6 so I can use it on T-Mobile or does the Verizon G6 not have the proper bands support?

Verizon doesn't lock their LTE phones. You should be able to drop a SIM card in it and have it work.
I don't know about all the LTE bands though.
I'm on Verizon. Seems everyone I had would work on most carriers out of the box. I had S7 Edge (Verizon) worked on a few different prepaid Sims. I also added a new phone for me and put a dif sim in my old LG Stylus and sent to my son in Boise. And put old sim in my LG G6 and it worked (cause I needed old number in new phone and new SIM went in older phone.
Hopefully that made since haha.
Just remember that the phone/SIM must be in good standing or you will have problems sometimes when activating on major companies. Unless its prepaid SIM you can pop a new one in that's already activated.

I'll have a chance to buy new Verizon LG G6 for cheap, but I'm on AT&T network. Just want to confirm before pull the trigger, do I need a Verizon SIM to activate the phone first then swap with AT&T SIM, or just put in the AT&T SIM would be fine? Thanks in advance!
Put the att sim in, during setup connect to WiFi. After setup input apn settings. Restart the phone. The phone may occasionally inform you that the inserted sim is not a VZW sim. I think that will go away after you disable all the VZW apps.
I have tried different sims but does not recognize the sim. Only recognizes verizon sim. I'm not a verizon customer and where I am at we don't have verzion.
any suggestions will be greatly appreciated.
Update: Working now. Sim card readers were bent.

I'm sorry but where I live don't have Tmobile or Atnt. I was getting 4g LTE with my carrier.
Is Galaxy S9+ Duos with Exynos SoC Dual Sim Dual VoLTE or 2nd Sim Card is 2G/3G only?
So, you will want to use two different SIMs and speak use VoLTE for both?
I think it's possible. I have never thought of it this way, but it should work (although I do not have any evidence to back it up)
Looks like SIM2 won't do LTE at all according to phonemore http://www.phonemore.com/samsung-galaxy-s9-plus-sm-g965fds/specs/3886
2G network SIM2: GSM 850/900/1800/1900
3G network SIM2: Not supported
4G network SIM2: Not supported
Data network SIM2: GPRS, EDGE

Sorry, but Phonemore specs are completely unbelievable. It's simply bullsh...
Galaxy S7 Edge, Galaxy S8+ Duos and Note 8 Duos (all with Exynos) have 2nd SIM 2G/3G capable. Why could S9+ have only 2G network on 2nd SIM, if older models have 2G/3G?
Galaxy S9+ Duos with Snapdragon SoC supports 4G and VoLTE on both simcards simultaneously. Is it the same with Exynos version?

Unfortunately non of this devices you mention supports 3G. You have to switch in settings in order to have suport 3G,4G for sim 2 and vice versa.
S8 Exynos (G950FD) supported VOLTE on both SIM but not simultaneously; the other SIM would no longer remain in VOLTE network mode if you selected that mode for one SIM.
It's a shame that below $100 xiaomi phones now support VOLTE simultaneously on both SIM but Samsung doesn't. I hope S9 series does.

If you find out that it does will you let me know please. Currently sitting on the Mate 10 Pro which does Dual VOLTE and Dual SIM 4G, if the S9 can do this too then I'll definitely upgrade!

Well, my pre-order is expected to be delivered by 17th March; I can test and let you know by then.
Will voLTE be enabled by default on unlocked phones? Or will I have to buy an operator modified ROM to have the option to use the VoLTE or Wifi calling services?
Thanks
Its Hybrid Dual-Standby config so unfortunately only 1 sim can be primary at 4G/VoLTE and other can be only 3G/2G at that time.
Yea, I've just got my S9+ Exynos and I can confirm: when 1st SIM card is connected to LTE/VoLTE service, the second SIM card is connected to 3G network
No Dual Sim Dual VoLTE.
Shame on you, Samsung. Half year old Huawei Mate 10 Pro is better choice.

:good: Confirmed in Exynos : Only 1 SIM at a time for VOLTE while the other on 2G/3G . You can use either one of the Slots for VoLTE

Now we need to wait and see if the Snapdragon version can do it.
Another question, if you disable LTE on SIM 1, can SIM 2 then connect to LTE. Or do you have to swap the SIM cards over?

US Snapdragon variant is a single SIM model

Just easy though - *#*#4636#*#* For switching your SIM on data to preferred band @esvlc @madnav @overgonas @jano7878 @Fenny @RossTeagan

I second that.
I just received my S9+ (via renewal of my mobile contract) and received a dual sim one (check by inserting two sim cards, it does ask for both pins and let's me choose the sim card to use for calling), although it was never advertised as such.
However, it only shows LTE for the first one.
Considering that the dual-sim version is marketed as specific "Duos" devices, those might differ - but I wouldn't bet on it.

Can you chose which SIM accesses the LTE or is it only the Sim in slot 1 that can?

S8 already can do this. Don't think it's exception on s9

You can do that within settings itself.
Problem is not with switching Band of Data SIM; but having both SIM work at LTE simultaneously.
Hello all,
Just bought a Samsung Galaxy S9+ dual sim (SM-G965F/DS) (G965FXXS7GSJ3) international model. Since I inserted my T-Mobile sim card I can only get the 4G signal and no LTE (also tried Verizon sim card and the same result). Speed test on 4G with a few different location (Northwest) and the result from 1.00mbps - 22 mbps max. I online chat with Samsung support and found out that USA don't support dual-sim and that's the reason I don't get the LTE service.
Is there a custom ROM or a way to flash my phone so that I can use the LTE service on my phone?
Thanks

Sorry but whoever told you they don't support DS sounds like BS to me, the carrier only see the phone signal, they don't know if it's coming from a single sim, dual sim or multi sim gateway device.
If you go into.....
settings --> connections --> mobile networks
and make sure both sims are set for LTE
1- 4G/LTE are the same. LTE/4G icon changes depending on ROM and carrier.
2- Samsung agent has no idea. It's a person on a generic building in India contracted by Samsung most probably.
If you own a dual sim s9+ you can get both modems/sims to work on 4G/LTE even at the same time.
If you see 4G you are working on LTE. Then what speed you get it depends on several factors, not just the phone or signal
