[Q] Switching Carriers & Unlocking Download Booster

i am currently on Sprint and have had it with their service. I live near Chicago, supposedly one of Sprint's maiden Spark cities, and their speeds have either stayed the same or have been worse than in the past. Because I just bought my phone under contract and other reasons, I am looking to jump to T-Mobile.
One thing I am considering is whether or not I should keep my current S5 or trade it into T-Mobile and get a new S5 from them. I know T-Mobile has the Download Booster feature unlocked on their handsets, but I am not sure if this is something deleted from Sprint's handsets before they sold them, or if the device is locked by the SIM or any other reason.
Has anyone else had an experience making this switch? I am curious what others have experienced.

u can not use Sprint S5 on T-Mobile anyway, time for new S5 if u made that switch.

In the past, that is true. The S5 actually uses a SIM card and can be used on a GSM carrier.

lookup Sprint S5 (CDMA) and T-Mobile S5 (GSM) then u will know what is the different.

I am fully aware the difference between Sprint's CDMA network and T-Mobile's GSM network. If you look at Sprint's S5 specs, it still has a GSM antenna. Here's my reference.

[Q] Sprint Note 3 to Verizon

I am thinking of getting a Sprint Note 3 since I keep blasting through my Verizon data in about a day and sprint is offering Unlimited data again. So my question I seem not to be able to find out is if I do get the Sprint Note 3 is it possible to swap back and forth with my Verizon Sim.
From my understanding Sprint/Verizon works on CDMA / GSM as well as Sprints Note 3 has a how to switch your sim on the site.
If this is possible what steps do I need to take?
Also to clarify I also do not have a Bill on Verizon it is a family plan just in case someone wants to ask why I want to have another carrier as well.
Thanks in advance.

T-Mobile S8 to Sprint

I have a T-MO S8, which I am going to pay off and have unlocked. I am interested in switching to Sprint for the 1 year of free service. Will it work without flashing Sprint software?

[HELP] How to get VoLTE to work on Cricket with BYOD S8?

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?

Flash AT&T on a T-Mobile S10+

If I buy used T-Mobile can I Flash AT&T firmware on it so I will have AT&T Enhanced Messaging and Wifi Calling Just as if it was an ATT phone????? Thanks

If the phone is network unlocked in theory the sim it sees when you first boot from setup it should then download all the carrier software and features. There is only one carrier U firmware so there isn't specific AT&T, T-Mobile. Now if AT&T tracks their IMEI's that were meant to be on their network then that may be where this all falls apart and some features may not come over then.
At least that is how it has worked in the past. Someone else feel free to correct me if I am wrong.

I saw a report on the forums here where someone flashed the att userdata and wiped and all of the carrier features worked.
I know on the 9/9+, even with the BOYD firmware, or flashing att bloat would not make a NON-ATT purchased device have advanced messaging /wifi calling / VoLTE. The trick was to activate that stuff on an att branded phone and then swap the sim.
It was very much a YMMV.

Similar issue here. My problem is i bought a s10 plus AT&T and it was supposed to be unlocked, however it wasn't the case. Mine is still AT&T locked and when i called them about my issue they said i would have to get service with them for a few months then i could end the service by paying the cancellation fee. I could then unlock the device. They also told me that my phone has an unpaid balance that would have to be paid prior to starting service. I have tried to contact the seller but to no avail. Anyways, my question is can I flash T-Mobile stock firmware to this phone and use it on T-Mobile?
