Hello! I've read a lot of posts but I'm unsure about how to do this...I apologize if I've missed something, but I'm asking for some help. I have a sprint note8 that's been sim unlocked from sprint and now has service with TMobile. Most services work with the exception of mms while connected to wifi. I've done all the apn stuff and the only thing that will allow mms is to get off wifi. This appears to be a common issue with T-Mobile port ins. I would like to flip this from sprint based to T-Mobile based to unlock all the features of the phone. I've read that there's a carrier switch and/or a carrier firmware. I don't know which one I need to do since the phone is sim unlocked. Can I get by with doing the carrier firmware only? Do I need to do both? Will my wife kill me if I lose all her stuff, yes. Thanks for any guidance you can provide!

I've searched for the answer for this, but found nothing...I apologize in advance if this has already been asked.
I have a Verizon Note 3 with a Tmobile SIM/Service, and would like to use the wifi calling/UMA feature that T-Mobile offers. In my office the network coverage is non-existent for all carriers, but there is wifi access. I can get online fine, but can't send a text or make calls. From what I understand Verizon has this feature blocked (or non-existent), Can I flash a T-Mobile ROM to activate this feature, or if I install a developer ROM, will this feature be available?
Thanks for any input!

I am looking for an answer to this. Did you figure it out?
Hey S4ers,
So I recently gave my friend my S4 (i337) restored to NB1. She does not have an active data plan, but I figured since I'm giving her the phone, it wouldn't matter too much.
She used to have an unlocked T-Mobile Phone working on AT&T, just running it on the EDGE network.
Anyway long story short, she cannot receive MMS anymore after using this phone. The phone has signal, but does not display E, 2G, 3G, 4G, or LTE. Just the signal bars. So I ordered an unlock code and received it, thinking that if I unlock the SIM that she could get this functionality. I tried the #0111*CODE# method in the dialer and receive an incorrect MMI message. Are there any other methods to unlocking the phone with the code that I have? No root would be ideal, because she has everything all set up on it, but I am open to any suggestions, really. I was wondering if I am going down the correct path in enabling MMS, by unlocking the phone like her old one used to be, or if AT&T needs to be contacted.
FYI, when we set up the phone, we called AT&T to register the new SIM, and provided the IMEI number, is it possible that they turned off any functionality because it was a smart phone without a data plan?
Any help would be appreciated, thanks!

What carrier SIM is being used in it? Also check your APN settings.
She is on AT&T and the APN is good. We had to get a new micro sim
G930V service switched to AT&T, root, firmware, and international service questions.
Hello,
I rooted my S4 a couple years back so I have an idea of how to go about this, but the fact that I have switched carriers has added more layers to my confusion when reading through the how-to posts on the forum.
I have attached my phone info. I have a G930V and I just switched carriers to AT&T. The only downside I've seen is that I can't send MMS.
To summarize my questions:
1) What is the most stable rooting/firmware to date? I have the all the latest updates pushed by Verizon, including the December 2017 security update. Most the guides on this forum are over a year old and trying to read through the dozens of pages of updated responses and procedures is giving me vertigo.
2) Is there any advantage to flashing G930A over G930U to my device? It looks like I can get all the AT&T LTE bands on either firmware and I don't care about using AT&T specific apps/streaming services.
3) Finally, I travel abroad regularly (Italy this year), and I would like to be able to buy a local sim card and minutes and use my device while there. Are there specific things I need to do/not do to allow this?
Any info/point in the right direction is greatly appreciated, I know the guys on here know there stuff .
you need to change your APN to your new carriers settings. Hence why internet ant MMS don't work correctly but calling does. This is because the modem works fine but the data is not getting through to the write network (or something)
google your APn settings for your new carrier and edit your APN in the settings of the connections.
good luck

Thanks, I did switch those settings and I have full functionality except for MMS.
I recently bought used Sprint Samsung Galaxy S7. It turned out the phone is locked to Sprint and is on bootloader v5. I called Sprint but they refused to unlock it even though it is paid in full because I am not the owner of the account that phone is associated with. I bought it from an electronics recycling company, so they cannot help with this. I would like to use it with a gsm carrier, like ATT or T-Mobile. What are my options here? Can the phone be unlocked by third-party? Even if unlocked, can the necessary bands and other settings be made available? Any hacks that trip KNOX are unfortunately not acceptable in my case (it seems putting U firmware with BL5 will trip KNOX).
IMEIGURUS.COM should have a carrier unlock for you. not saying its free.
That is fine but after it is unlocked would I be able to use it with t-mobile or att without issues? I read a lot about LTE frequencies locked, missing menus to set APNs, etc.
It is fine if the answer to my original question is to simply get rid of the phone. I am already considering this, as I naively thought that all it would need is a call to Sprint to unlock it and then flashing the U firmware.

There is a thread here about unlocking additional LTE bands.
