Hi, a friend of mine bought a straight talk galaxy core prime in the US as he goes there for 6 months of the year to vacation.....it's not on a contract and they told him the phone would work in canada, problem is I put a Virgin Mobile sim in it and it says unknown in the settings of the carrier?.....Can these phones be used in Canada?, do i have to flash a custom firmware or for that matter a canadian firmware for this phone to work in canada? Could someone please help me.

I'm under the impression that Straight Talk branded phones usually don't work well with other companies' SIM cards... on the flip side, they advertise themselves as being able to bring your own phone to straight talk by having them provide many different types of SIM cards for your unlocked phone. If you find a solution to this, can you post a reply, as I am curious about this as well.
I've searched and cant find anything but the bands for either service. Which they use a lot of the same. Is a T-Mobile branded S8 usable on Verizon? Full 4G or not? Thanks!
its a gsm device. i believe the internet data part will work but not phone calls

Darn. I was hoping since they all have the same model number that it would be possible.

Call Verizon with your IMEI # and they can check if it's compatible with their network.

Did you ever figure out if this was possible? I can't seem to find a definitive answer.
Bump - anyone know if this will work?
As soon as I get mine unlocked I'll let you know as I have Verizon. All s8 models are the same but I'm sure the T-Mobile software has blocked Verizon bands. I'm sure if you flash Verizon software it will work just fine.
I have an unlocked T-Mobile Galaxy S8+ and it does not work on Verizon. I went into a Verizon store and they tried for an hour to activate the phone to no avail. They tried multiple different SIM cards and none of them worked. If anyone has better luck, please let me know. But they weren't able to figure it out at Verizon.

You need an unlocked Tmobile S8 or S8 plus.
Read the instruction in "Flash any carrier 100%" to flash to the carrier you desired, activate all bands.
Then use it on Verizon.
You need to flash your phone to Verizon to work. I did the exact opposite actually. I bought a Verizon device and flashed it fully to T-Mobile. Works perfect on T-Mobile because every US Galaxy S8 for the major carriers is SM-G950U. They support each other's bands, their just disabled by the carrier firmware.

Don't know about Digits because I don't use it, but Wi-Fi calling does work. I get the T-Mobile boot logo too.

I did not have any luck flashing it to the official Verizon Firmware, but I was able to flash it to the G955U1 firmware. The official unlocked US Firmware. Make sure your t mobile device is SIM unlocked by TMOBILE before you do this.
1. SIM unlock device by tmobile (pay off device, meet the 40 day requirement, etc).
2. Flash to G955U1 (S8+) or G950U1 (S8).
3. Insert Verizon SIM or ATT or any SIM.
4. Your phone will give you pop up warning saying it needs to restart to configure the new SIM.
5. Enjoy your new carrier.
Did you use a Verizon SIM and did you get both VoLTE and WiFi calling to work with the G955U1 FW?
my 2 cents

I went to Verizon store and used one of their Verizon SIMS from a display model of the S8+. Voice over LTE works, Data works and I was not able to test Wifi Calling at the store. I even ran a speed test and had about 27mpbs down and the associate ran speed test on his phone and he got about 20mpbs down connected to the same server using the Speedtest app. I ran the LTE discovery app and shows me connected to LTE Band 13.
Hope all of this helps.
Bringing S8 to sprint?
Did you anybody try to use a TMobile or other branded S8 on Sprint? The Sprint customer support is not able to add the IMEI to their database for whatever reason.
@Aephel
@T33H00
Silly question, but does doing all this void Warranty? or is there no such issue anymore?
For example flashing Verizon Firmware onto a Tmobile Unlocked.
I unlocked my t-mobile s8 plus and attempted to use a Verizon SIM. It does NOT work. Verizon states that the IMEI is not in there database and that they cannot activate it.
This has been discussed before but I'm still not 100% clear.
Can I buy an unlocked Galaxy s8 plus that comes from a different carrier (say Sprint) and flash the AT&T firmware to it, changing the carrier identity so that you get features like wifi calling and VoLTE?
Thanks!

Yes you could get it working with wifi calling and voice over LTE no problem but you got to make sure that if you get a phone like from Sprint/Verizon / T-Mobile unlocked before trying to carrier switching

Thanks for replying. So make sure I have this right.
If I purchase a Verizon/Tmo/sprint Galaxy s8 plus and put my AT&T sim in it and it activates on the network and allows me to make/take phone calls then I can assume that the device is unlocked. If it's carrier locked that should not work.
Yes that is correct but if you want to have all the AT&T features you must carrier switch following instructions here on XDA which will convert your Verizon/ Sprint S8 phone and to a completely AT&T phone

Riddle me this. I have a guy trying to trade me an S8+ att version for my OP5. He says it is unlocked. Can I flash unlocked firmware on it to get rid of any bloat and all the att stuff in the background that will be taking my data?
Hi,
I see Samsung has sales on S8+ from US Cellular for less than the one from ATT.
If I buy the US Cellular one and insert my ATT SIM, it should rebrand it as an ATT phone right?
At that point, will it work and behave just like an ATT phone or will ATT block/prevent the stuff like VoLTE/HD voice/visual VM etc as it is not a true ATT branded phone?
thanks
It is unlikely to work that way. After you purchase you will need to have US Cellular unlock the phone. If buy it outright, they may do that but you will want to check with them first. If you buy it unlocked as mentioned in the title it should be ok.
Once the phone is unlocked there is no reason it wouldn't work on AT&T, but it will not rebrand itself. You will need to load AT&T branded firmware on it to take advantage of VoLTE.

Are you sure? From what I've read 1) US Cellular phones after a certain date come unlocked (forget the exact date but it was before the S8+, so nearly certain it is unlocked) 2) the US S8/S8+ will rebrand based on the inserted sim (from the galaxy s8 reddit PSA announcement old.reddit.com/r/GalaxyS8/comments/7jdcno/psa_with_the_latest_us_carrier_updates_your_phone/ )
So it will brand and push ATT firmware
That's why I was asking specifically if things like VoLTE would work in case someone else has done this. It seems ATT is more restrictive about allowing certain features than other carriers

That may be true of US Cellular, they do seem to be pretty customer friendly. I had interpreted that the device will configure the hardware to operate on whatever carrier's SIM is in, but not the firmware. However, I have not tried this with mine. I do have a branded S8 that I have put unlocked firmware on and it stays on that firmware.
If the phone is not carrier locked and you put an AT&T sim in it, then it should work on the AT&T network. You will NOT get VoLTE/HD calling or Wi-Fi calling. Regular calling and LTE+ data will work fine.
It will not automatically download the AT&T firmware and become an AT&T branded phone.
I do not know what will happen if you put the AT&T firmware on it. I asked if anybody had switched to the AT&T firmware and gotten VoLTE or wifi calling, but did not receive any answers.
I have an unbranded phone on AT&T. I've not gone through the trouble of switching to the AT&T firmware.

I have not tried. Other than VoLTE and wifi-calling the phone works perfectly, and I've never had to reset it, so I've not bothered to try and change firmware.

im looking for the same thing.
nope they wont let you unlock from their service...tracfone told me it wouldn't work on there new and improved network so they offered me a $40 rebate off any new tracfone over $80....I cussed and argued for two weeks with no avail...I had another old tracfone and was also running on that old Verizon cmda network, well they activated it..I put the sim card in the galaxy and it works fine....they just wanted me to buy a new phone...well i get on the phone with them to tell them that I got my 902l working on their "new network" ...they said that I was a liar and that the imei for my phone was never even branded with verizon/tracfone ever....I said cool and let them go with what the computers show...I figured out that since i'm flash happy with ASOP pie ROM's i knock out my radios or whatever all the time...so when my phone doesn't work my imei# is also blank slated meaning no carrier or csc identifiers...which means that you have a good chance of getting Boost mobile or metroPCS to work...I'm from Knoxville, TN and I called every carrier trying to get service when tracfone went loopy....Boost will activate it for sure because they run the old cmda...I'm good with tracfone I've always used there service...but I will say that I do have a Tmobile 900T motherboard i got for $10 off ebay on the way because I'm needing bootloader upgrade so I can use my fingerprint sensor on these newer ROMS...And the GSM radios so i can just go with whoever carrier I feel....
