I contacted Sprint to activate my unlocked T-Mo s9+ but they were not able to do so online and at the store.
Like the S8+ this phone has the CDMA bands for activation on Sprint. Any one else encounter this issue?
Do you have a Sprint SIM?

Yes the rep at the store gave me one too but could not add the device to the Sprint database. A ticket had to be created so they could try to add it.
In my experience only the Verizon and Sprint branded phones unlocked will work with any carrier. Generally the AT&T and Tmobile phones only have GSM radios so they won't work on Sprint.
Were you able to resolve this issue ?
Hey were you able to resolve this issue ?

OK so after one 2 many beers I purchased a sm-n900p off EBay on sprint. I am based in UK and we use GSM. Only just realised the handset is CDMA. Am I now stuck with a useless phone or is there anyway I can flash it or do anything for my O2 sim card to work on it?

There is currently no way to unlock the phone for international SIM without being a Sprint customer and having the phone activated on an account.
more info needed

can you explain more regarding having sprint customer?
from a lot of forum threads i'm getting Bias information:
so, It is possible to use GSM international but nobody can do that unless Sprint authorize person do something to the phone or account?
so Unlocked version doesn't exit? or what Unlocked mean on SM-N900P?

the phone can only be unlocked for International SIM cards by Sprint, and for this to be able to be done, the phone has to be activated on a Sprint account. this is the ONLY unlock method currently available for this particular Note 3 model (Sprint variant, SM-N900P)
So my Verizon contract expired so I hopped over to T mobile and got myself the S5. Tmobile's service has been appalling IMO and I want to switch back to Verizon. Will my S5 work on Verizon? Do I have to do anything with the phone? I have had it for over 40 days and from what I have read I just have to bring it to the tmobile store and ask them to unlock it. After I do that will I be able to take it to the verizon store for service? Thanks!

Verizon is CDMA, tmobile is GSM. So, no. They have different bands.

I thought this was not an issue because my understanding is the 900T was basically the international edition of the S5 so it had all the different bands. Why is it legal to even sell me a $650 phone that is locked to one provider?
What carriers CAN I use this phone with?

Anything but Verizon or Sprint. You're correct that it's pretty much the international edition, but other than Japan and a few other countries, everyone uses GSM. As to why it's legal, blame Verizon and Sprint, not the 99% of other carriers.

I took mine to Verizon and was told the LTE bands weren't the same as theirs. I showed them that the unlocked TMO S5 does in fact have the required bands. Finally, the manager admitted that it is Verizon's choice NOT to accept other carrier's phones. At least he was honest, so I'm not blaming him.
I am still on VZ's unlimited hotspot, and I use a LOT of data (over 25GB last month. I was ready to give it up just so I didn't have to carry the little bugger everywhere. When I found this out, I went back to Consumer Cellular with my phone, and it seems to have the same coverage as VZW. VZW can keep feeding me the GBs since they won't accept my phone... and I'm paying less lol.
Based on what I read so far, only unlocked version of AT&T will work only with GSM provider. Would like confirmation of this. Thanks!

Unless something has changed, Sprint is CDMA, not GSM.

An unlocked AT&T GS8 will work on other GSM networks but not on Sprint b/c Sprint won't add the AT&T GS8 IMEI to their system.

The hardware on all the s8's are the same so technically it will work but the imei isn't white listed so you won't be able to activate it on sprint but the sprint version can be activated on att or any other gsm provider.
Sprint galaxy s8 works with tmobile and verizon

Hey there. I have an S7 Edge unlock from t-mobile running the unlock firmware from G935U. Sprint SIM cards are lock, I have a friend who works for sprint. I have 3 Sprint S8 and S8+, 2 unlock and running on T-Mobile network. I took 1 of the SIM card and put in my Unlock S7 Edge, the phone just keep trying to connect to network and repeating the same process. Didn't work at all, but the Sprint S8's works excellent on T-Mobile network after flashing the UNLOCK firmware.
---------- Post added at 03:01 AM ---------- Previous post was at 02:53 AM ----------
I got 111.71 mbps download, 20 mbps upload speed from my Unlock Sprint S8+ running G955U1 unlock firmware on T-Mobile network. Couldn't ask for anything more than that.
I will provide my non Sprint S8 variant experience.....for any US S8, they all have the same hardware. I have noticed that ATT and TMO models have CDMA hardware, but are turned off in the carriers version of the firmware . Flashing the stock unlocked S8 firmware or the Sprint/VZW FW will enable the phones for use with CDMA and all LTE bands. I had an ATT version sim unlocked and attempted this on Verizon FW with a VZW sim and it worked perfect....but there is a major roadblock with Sprint. Sprint is the only carrier that I have tried that requires an update of the IMEI to the account (ie you cant just pop a sim in and the device works). VZW for example shows Unknown device on the account instead of an S8, but all the services still work. Sprint shows 3G for about 5 minutes, then you get a message that the sim is locked and to reboot or call support (not the same as the phones sim slot being locked, but more that the system cant register the sim/device combo). Sprint stores have the capability of adding IMEI's to the Sprint database, as long as the IMEI does not come back as ineligible. Well, I took the S8 to several stores and none of them could add it to the system. Several employees advised me that the IMEI's from other carrier's are blacklisted so that it can not be added and the only ones that the system would allow to add are IMEI's that were sold as unlocked or Sprint branded. If the IMEI can be white listed, then I am certain it would work.

Yes it will work, i put a freedom pop sim in, and it restarted with at&t logo

I had a similar experience with an Unlocked Galaxy S7 and Sprint. I actually had to get Samsung Tech support on a conference call with a Sprint Manager, because Sprint told my customer the the phone is incompatible with the Sprint network. After embarrassing the Sprint rep, he white listed the IMEI number on Sprint's network and the phone worked.
Also, MetroPCS has the same policy. You cannot just pop in a Metro Sim card. You have to call them and register the IMEI number. After about an hour tops, the phone will complete provisioning and be able to work on Metro's T-Mobile network.
T-Mobile is instant. You cab pop a T-Mobile Sim card into any sim unlocked variant and it will work. However you will need to go into settings and follow the T-Mobile instructions on how to set up the radio frequencies. The better way is to just flash the carrier's ROM version onto the phone. This way you will get the features and updates from the carrier. Carriers seem to get the Android updates faster than Samsung. A trade off for bloatware.

Maybe I should try this approach with my Galaxy S9+ (AT&T, unlocked).
Sprint is a PITA.

You may have been referring to me regarding the unlocked Galaxy S7 & Sprint. Many thanks for that one. I'm going through the same crap now with Universal unlocked IPhone 7. Sprint is a PITA!
I can confirm the SM-G955U from AT&T does work. I confirmed this via Sprint site. Just Google Sprint byod eligibility and you'll find the link.
My biggest roadblock was AT&T had a network lock on my phone so the sim Sprint sent couldn't be used. I then used the services provided by gsmzambia to network unlock the device. It's currently working on Sprint network.
USA snapdragon.
Any frequency issues? Can they be fixed?
Any T-Mobile features not useable?
As far as I know (saw on other threads) T-Mobile supports all versions. Or better said, T-Mobile won't block any features if you use another phone on their network.

Hi can you tell me how you unlocked att s9 plus, i'm not able to unlock with att or third party unlock site, thanks in advance.
Mine is bought outright.
Then requested unlock code on at&t site.
An independent dealer told me her att phone wouldn't do hotspot when on tmobile.
Maybe that varies per phone model and/or android version.
Would have to try to be sure.
Hi,
Have an unlocked ATT phone on Tmobile, wifi calling doesn't work.
That's why I'm staying on att...plus asking around, tmobile still needs better coverage here.
Hello,
I just bought the S9+ unlocked today at best buy. I love the phone and I opted in for unlocked version so that I can root the thing later if I wish.
So, I would really like to have the HD voice option, but I found out that you need a carrier phone to be able to have wifi-calling and hd voice. My parent can hear me great on their end (they have iphones) but on my end I have the same old ****ty voice quality.
Is flashing ATT firmware (and getting their bloatware) the only way to get the option? Right now, when I go into settings-> connections-> mobile networks, the option isnt even there.
Reason is the same as I posted on a different thread. Flashing at&t firmware will not fix the problem. Subsequent comments in the thread may be of interest.

Ouch. That sucks. I read somewhere that tmobile and sprint don't lock unlocked phones out of their volte and wifi calling. Does Verizon use same tactics as att or will they make it available to me as well?

Yeah att doesn't have volte on any unlocked Phones. I put a sim in my Sprint S8 and it dropped to H+ during the call where TMO and vzw stay on VOLTE on my phone.

Same issue in Canada - Carrier Unlocked device purchased do from Samsung & none of the Canadian Carriers support VoLTE or WiFi Calling - This is extremely unethical on the part of the partnership between Samsung & the Carriers! We all know that the Carriers are Samsung's biggest customers - But to make key features unavailable is unconscionable! ?

T-Mobile and Verizon customers both get VoLTE on Samsung factory unlocked phones. AT&T restricts by IMEI (as well as requiring their firmware). Sprint does not yet offer the feature at all on their network. It is unclear whether unlocked devices will get it once they do deploy it. Time will tell.
