My original post was intended to just be a question about the upcoming S8's dual-sim possibility... however this thread ended up being the main S8/S8+ thread, so I'm modifying my original post to include some main points that we've gathered about the device and provide some useful resources: Misc FYIs ------------------------------------ All MSLs appear to be 000000 To force band 41 only (thanks Terrell352): ##DATA# MSL 000000 then go to LTE and turn off b25 and b26. ##debug# works on this device (thanks nexgencpu)Cleaner way to look at carriers,CA and signal strength etc.. Want Root permissions? This will trip KNOX and you won't be able to use Samsung Pay or other KNOX features
Galaxy S8 or Galaxy S8+
Carrier/Dual Sim Info ------------------------------------ I have Sprint (obviously), but I have property where the only carrier is AT&T. FreedomPop now has a free AT&T SIM you can buy for limited voice, data & texting, which is perfect for my limited needs when I'm at my cabin. Converting the phone to a Dual-SIM phone then becomes convenient for me with the FreedomPop SIM + Sprint. With that in mind, here is some useful info (including a solution below): See what frequencies/networks your phone supports: https://www.frequencycheck.com/ All networks are shipping the 'U' version which has support for all US networks but are software-locked. Once unlocked they will work on any US network. Dual Sim version not available in US or UK. The International Dual Sim model S8+ is SM-955FD. You can convert your single-sim US model into a dual sim by 1) unlocking and 2) add a $50 dual-sim adapter from magic-sim or simore (I bought the Simore one and it ripped before I could even try it once. They would not refund) If you are within a contract and/or didn't pay full price for your phone and don't want to wait, you can unlock your phone: https://theunlockr.com/unlock-my-phone/ usually for something like $20. Correction: These unlockers don't work for CDMA Sprint phones. You have to either buy an Unlocked phone or get Sprint to unlock it for you. Correction2: There is at least one guy who knows how to do it! See 'Solution' below. You can convert it into a Dual-SIM by adding one of these: http://www.magic-sim.com/ or http://www.simore.com/ (don't recommend simore, mine tore easily) I found a ---> SOLUTION <--
Charging/Cables
----------------------------- Info from mmark27 Remember only buy stuff that's been approved by Benson Leung, the Google Engineer that tests tons of USB-C items. You can search him on Amazon. USB-C crappy products can fry your phone and start fires. From what I (mmark27) understand, the phones are only Quick Charge 2.0 compliant officially. They may pick up QC 4.0 compliance at some point as the chip supports it, but for now QC2.0 is the safe bet. choetech fast charging pads don't work Seneo fast wireless charger do work micro-female to male USB-C USB-3.0 to USB-C Wireless charging pads that look just like the ones at Best Buy from Samsung Pleson fast charging pads work with S8 and S8+ https://www.amazon.com/dp/B01MRXM473/ref=cm_sw_r_cp_apa_Kv5-ybKG6TSZP
Noteworthy Specs -------------------------------
Only difference between S8 and S8+ is screen size and battery size. Bezel free, all screen design No physical home button 5.8" & 6.2" Plus Version 'Infinity' QHD Amoled Display 12mp f1.7 rear, and 8mp f1.7 front cameras, auto focus Wifi Calling Dual Edge Only Display Bluetooth 5.0 for double speed and four times the range 3000mAH (S8) & 3500mAH (S8+) battery, fast charging 4 GB RAM Waterproof 64 GB built in storage Bixby Artificial Intelligence, dedicated button Iris Scanner Pressure Sensitive "3D" Touch home button Wireless Charging Can see screen with polarized glasses, unlike with LCD screens (HTC 10, etc) Always On Display PC Replacement (DEX) Fingerprint sensor on back DOES have a headphone jack USB Type C MicroSD Expansion HPUE compliant, which means it will extend existing signal range by 30%, including indoors!In my limited experience with the device, HPUE DOES work. Maybe it doesn't help speeds, I don't know -- but in 2 locations (in two different states) where I normally have no signal, I can now make phone calls and transfer data with a weak signal that I never had before.
============================ORIGINAL POST=====================================
I'm planning to upgrade to the Galaxy S8 when it's available on April 21st...
I would really like a Dual SIM version and have Sprint as my primary carrier and use a FreedomPop ATT SIM as a 2nd option when I'm up at my land which is only covered by ATT.
After some research, it seems that the Dual SIM version is the 'International Unlocked' version which does not have the capability of CDMA/CDMA2000 for the 3G/1X portion of Sprint coverage. Since LTE is actually a GSM protocol it has the capability of doing Sprint's LTE, but other services may be limited.
Is this correct?
If so, that probably means I just want to buy the Sprint version and get one of those little dual sim adapters you can now get like this one: http://www.magic-sim.com/
Also, in order to use a SIM from a GSM provider, the phone needs to be unlocked, which outside of contract means I'd either have to wait 2 years, or just buy the full-price phone outright, and then get it unlocked.
Then I can use my ATT SIM, but again coverage may be limited because the radios are tuned for Sprint, not ATT. But I think it may be possible for some of their services to work.
... does this understanding sound correct? Is there another way I can go about what I'm trying to accomplish?

I'm here looking for answers to a simple question. Where is this mystery Sprint signal coming from? For the past few weeks I've received a signal on multiple Sprint devices, two Sprint devices with roaming turned off, and two Virgin Mobile phones and Virgin Mobile phones can't roam, the other rate plans might be able but I'm talk about Virgin Mobile devices from before they introduced all those other plans. What I'm making clear is these devices have to be picking up a Sprint signal, plus I've downloaded the SignalCheck Pro app which has indicated two different signals 1XRTT and 1X800.
The signal only last for about 8 hours each morning and begins coming in and out towards the end of each morning. I try making a call and it fails, and it doesn't get any data at all. I try each device and they all do the same thing they have a signal and very strong signal with no data, and voice doesn't go threw, I haven't tried sending a text figured no data, no voice then there must be no text.
I read about some "projects" that Sprint has going on Project Ocean and Project Cedar. Since Project Ocean is suppose to be taking place in Missouri and I live so close to the Iowa, Missouri line, I figured if there is a tower going up maybe it is possible I'm getting a signal from it, in the early stages. I really don't know what is going on, if Sprint is launching service, putting up new towers and that signal finally comes, and stays, and works. I'll be back full time on the Sprint ban wagon. Unfortunately, I live in an area not served by (according to experience and coverage map) Verizon, AT&T, T-Mobile and Sprint. Not even the two Iowa carriers i Wireless or Chat Mobility serve my area, go 10, 15 or 20 miles in any direction your good, here, wireless dead zone, no choice of carriers. And if Sprint puts a tower here if I finally get an answer and learn that signal will soon come and stay and work I'll finally have a choice.
So if anyone has any ideas, has experienced this in other parts of the country or has any idea what could be going on please say. Any information is better than not knowing, and together maybe this will be answered.

Try to make this as short and simple as possible. I have three devices; 2 of which are on the same plan and the third on a separate plan.
The third device is my tab 4 which is picking up SprintB41 site 310120 just great. I get 3 bars downstairs.
My other two devices; Galaxy Note 4 & Galaxy Note Edge for some reason will not pick up this tower. I have tried PRL updates, Profile updates, restarted the phones and all I can get them to connect to is a ClearwireB41 site.
More background info...all devices have same Sim card as when purchased, tablet stays off 3/4 of the day and my phones are on when I wake up and turn them off at night. No matter where I go inside or out my phones won't connect to the Sprint site.
Anybody have any ideas before I call Sprint trying to figure something out? I'm not sure how long the tablet has been able to connect to this site so I'm not sure what to think of it besides agitated that the tablet of all things is connecting. I posted two photos; one of the tablet connected to the Sprint site; second of the Clear wire site my phones connect to.
Thanks in advance.

The real question will be the effect on the upcoming 2.5 EBS auction. T-Mobile might be able to get very good prices with almost no implementation costs for much better service in small cities and rural areas. -

Auction 107: Hit $80.9B. Now going to enter the assignment phase where bidders can bid on specific spectrum blocks. Wonder how fast this will get online this year. TMobile's head start with 2.5GHz is gonna get challenged. I could see them taking the lead in wireless tests in 2021 but then the gap close in 2022. Auction 108: Three blocks. 49.5, 50.5 and 16.5MHz. I wonder how heavy TMobile will buy here. It'll sorta clean up their holdings and I could see down the road if they don't bid they have to invest more time keeping interference out of the current existing white-space. Likely at least secure entire counties they already own a partial license in. Everything about 2.5 is such a mess. -

So very interesting find , at my home The 5G upper layer indicator was turned off on certain LTE bands, but still has NR connected. It was on a Band 30 5 mhz one tower, a Band 30 10mhz chunk on another, and my home tower the Band 2 5Mhz chunk now has no indicator on. I am wondering if they are maybe configuring the the tower for DSS NR band 2 -

Seems to be the norm in many markets. They're replacing nearly all existing antennas on sites here in New York too.
