I switched over from AT&T to cricket since it was cheaper. I knew I'd be missing out on somethings but since Cricket allows Wifi Calling on certain phones and the iPhone I thought it would work on my Galaxy S7. Has anyone had any luck getting Wifi Calling working on a MVNO such as cricket? On the original 930A firmware the option was grayed out once I put in the new sim card and it's nowhere to be found when I changed out the firmware for the 930U firmware.
Cricket doesn't support WiFi calling on the S7, not even on the Cricket model (G930AZ) which I own. They only support WiFi calling on iPhones and their own versions of the Galaxy Amp Prime & a couple of LG phones.
this is my first samsung device, can you tell me how to flash G930U firmware on my G930A?

I've been combing the forums and I'm still unclear on a few things and looking for help. Current AT&T customer and I plan to switch to T-Mobile soon. Any confirmation or corrections/answers to the questions/statements below would be really appreciated.
1. The 935F variant is the international model that works with all GSM carriers (and I assume without any carrier bloatware) but VoLTE and wifi calling will not work on any GSM carrier here in the US. Theres a secondary 935F model (d?)- whats the advantage there? Shopping tools that let you compare the models show no difference but always priced differently. There is something I'm missing.
2. The 935U variant is official US unlocked model for use with any carrier. Only silver. I have not seen any posts confirming that VoLTE and wifi calling works- and will continue to work if you switch carriers.
3. Lots of listings for factory unlocked 935A variants. Official AT&T version. That just means a reseller has applied unlock codes to each and resells them? I'm very unclear here. Listings always say compatible with all GSM carriers. But will AT&T bloatware, logo continue to survive? And again, will VoLTE and wifi calling work and continue to work if I switch carriers. This is also the cheapest phone to buy virtually new. But if truly GSM compatible with features that are important to me are intact among carriers- what would I get for the significant premium to get the 935U? Besides, I wanted black.
4. Black Pearl- has this been released in the US and in any specific model? I have not seen one.
Thanks in advance. Really appreciate it.
FD is dual sim. You can put 2 GSM simcards there and both are active. Can send and receive sms or calls.

You can install 935U stock firmware on att/tmobile/verizon version. If used on tmobile network, you will get wifi call and volte. For att you have to install or have att stock.

1. 935F is the European / International model. 935FD, D stands for Dual-SIM, both slots will be able to accept a GSM SIM card and are usually used, as one for work, and one as a personal number. Dual-SIM however, is not a popular concept in the US.
2. Check the 935U threads, if a CSC flash is possible, it might work. Though, I'm not sure.
3. Yes, if you have an AT&T phone, it'll still have the AT&T ROM, which will always remain the same, regardless. It will work with other carriers, meaning SMS, Data and calls are compatible, but things like VoLTE and WiFi calling might not work on the carrier that the phone isn't intended for.
4. No it hasn't. It's been released in South Korea with 128GB of internal storage. Also available in the UAE, India and some other Middle Eastern countries. Only in a Dual SIM Configuration (SM-G935FD), and with 128GB of internal storage. It's a limited edition phone, and not sure if it'll be launched in the US.

A couple of followups if thats ok:
1. So if I purchase a "factory unlocked" 935A, before I insert any SIM, I can immediately flash the 935U firmware and it will remain unlocked? I couldn't find a single post that said VoLTE or Wifi calling worked with the 935U firmware on T-mobile (AT&T- what do you have to install?)
2. Flashing to firmware is not considered rooting the device? My work will not let my device connect to the network if it is rooted.
Seems like there is no reason to spend the extra money for the 935U variant. I can save hundreds and purchase an unlocked 935A and flash the firmware. I've rooted devices before and the process looks similar.
Thanks.

According to other people in verizon 935u thread and att 935u thread, volte and wifi call works on tmobile. For att wifi call and volte, it must be a ATT carrier firmware. ATT only let their branded phones have wifi call and volte while tmobile allows any phone to do this. That's why with 935U wifi call and volte will work fine on tmobile.
Every time you insert a new sim the phone will adjust settings, so there's no relation with what you can install.
Flashing is done through Odin while phone is in Download mode. There no root involved.
Hi all,
Been through a few thread but didn't get a definite answer as I would like to flash my VZ s7 edge to be on T-mobile as I don't mind the carrier float wares. I just want it to work as the phone is bought from T-mobile. I know it's possible but does everything work including unlocked the T-mobile LTE band? Wifi calling or VoLTE etc.. I wasn't sure if the software will unlocked the bands or is it restricted to hardware limitation. Would you recommend the U firmware or T-mobile? I am trying to give the phone to my nephew as he's a poor college kid using S3 and he's on T-mobile. TIA.
Yes it works. Just make sure you flash T-Mobile firmware
If you flash the U firmware for the S7 Edge, its modem should have all bands available as well.
You might just have to root it and make some adjustments to the CSC.
Anyone know how to get VoLTE to work on cricket, with a non-branded cricket phone? Cricket is telling me it has to be a Cricket-branded phone. Does that mean specific IMEIs or could I just install Cricket S8 software?
Also, does anyone know if VoLTE will work on Straight Talk using Verizon's network? Thanks for any help.

I would think flashing the cricket firmware and csc would be enough as they are not lying the prscess to convert a non cricket BYOD is rough I Tried on a verizon LG G5 And still never got it working properly

I will try this. Do you happen to know if Cricket is 950u or 950u1? I can only find AIO (cricket, i believe) for 950u1. Would I need to change the CSC if I use official cricket firmware?

I believe so on the csc but there is 950u1 and u2 you have to look in your settings to see which you are on the u1 or 2 is the bootloader version f it is u2 U cannot flash any U1 firmware
Verizon prepaid was great with VoLTE BYOD. All 3 of my family's phones worked (HTC U11 unlocked, iPhone 6, Samsung J7 Verizon). It was beautiful sound quality. I had to ditch Verizon, because, despite having a strong signal, 4G LTE data performance was very unpredictable. Sometimes my download speed was essentially zero at my home, even though I had 5 bars. One morning during a power outage, I had a good strong signal, but I couldn't bring up a single website using the HTC U11. The Verizon branded Samsung J7 wasn't much better. I called Verizon prepaid support a couple days later, and they had me do the usual ridiculous insulting troubleshooting where they try to blame the user/device. Also, I did hate that there was no visual voicemail app for Verizon on prepaid plans (makes no sense). That being said, I went back to Cricket in order to get normal LTE data performance, even though I get one bar of signal at my home. Now, back on Cricket, the sound quality has returned back to horrible when I call home from work, but data is pretty good. Also, I cannot stand that my unlocked HTC U11 cannot use the hotspot functionality on Cricket without my paying extra. The HTC One A9 my family member uses can serve a hotspot, probably because it's S-OFF and rooted. Verizon prepaid allowed anybody to serve out a hotspot for free. Today I tried an experiment. I called home using Google Duo. My phone and my family member's phone have Duo installed. The sound quality was incredible and sounded just like HD Voice. Essentially, it was a workaround to get VoLTE. The phone at home was on WiFi, and I was using 4G LTE. So, my poor-man's HD Voice will end up carving out bytes from my data allowance. I don't know when and if Cricket will open up all VoLTE capable phones like Verizon did. It bugs me that Verizon had this weird data issue, because Cricket seems to be game playing even more than T-Mobile and Verizon do. I was tempted to try T-MOB again, but they have this ridiculous policy with their prepaid family plan where you have to make a deposit that they keep for a year. Who does that?
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.
I bought my S8 unlocked from Samsung. I love the lack of bloatware. I recently switched to Verizon from AT&T and when I'm in my home office (I work from home), my cellular signal is nearly non-existent. The two options I can see are to switch to the VZW firmware to enable wifi calling or to by one of the network extenders. Can anyone offer opinions? How bad is the carrier bloat on the VZW firmware?
Thanks,
Craig
