[Q] Which one to get? Which version uses what bands? - Galaxy S 4 Mini Q&A, Help & Troubleshooting

My S3 mini broke. Now I thought to get an S4 mini, but I can't figure out which one would be the right one.
I am using a plan in the US, ultra mobile, which is on the T-mobile network I think. I also often use my cellphone
abroad with other sim cards. I've seen that there is a 16GB version available - SCH-I435 from Verizon.
I can't figure out what bands this phone uses.
http://en.wikipedia.org/wiki/Samsung_Galaxy_S4_Mini has no info on the bands.
http://www.samsung.com/us/mobile/cell-phones/SCH-I435ZKAVZW-specs says:
LTE: Bands 4/13 CDMA 1x/EVDO Rev A. 850/1900 MHz.
Are there any other 16GB versions? What about root/rom? Any significant differences? Which would you recommend?

Its more like do you want LTE or 3g support, any international unlocked version will support all bands
Afaik verizon its CDMA and dont use a sim card therefore can't switch sim

I see. That would be bad. So the verison one can not switch SIM? Which means it can't be used in europe?
This post implies that there is some kind of SIM on the SCH-I435. But I don't exactly understand what works and what doesn't.

Well Im really not sureim not in the us, but I remember a friend had a Verizon phone and can't be enabled in my country because didn't have Sim slot and all carriers have Sim buy was months ago that could have changed

If the info is of any help, I have a GT-I9195 model (currently connected to Spark, NZ) that claims to have 16G of memory and, in this case at least, is unlocked. It takes a mini-SIM, but that's not unusual now days.
Given that most phones in NZ are sold unlocked and people expect to be able to swap SIMs from one phone to another as well as take their current phones to another network, I'm guessing it supports most bands.

Dual Radios, CDMA and GSM?

Will this phone have dual CDMA and GSM support?
I've read it will. Click the link below.
http://www.phonenews.com/sprint-htc-touch-pro2-images-surface-7908/
If so, I wonder if we purchased a Sprint one, could we unlock it and use it on a GSM Carrier like AT&T. This is a hypothetical question.
If it supports GSM, does this mean it would HAVE to support SIM cards?

No, because the GSM radio only supports international frequencies (not 1900). The purpose is for you to roam or use GSM networks overseas not in the U.S.
Example, i want to go visit my sister in the U.K. I land at Heathrow, buy a prepaid SIM from say O2 and pop it in the TP2. If i'm back in the States, i use Sprint's CDMA network.

[Q] Verizon model - Sim Unlock Possible

I am interested in getting the Verizon model for how cheap it is. Is it possible to sim unlock the Verizon model to use on T-mobile?
I know someone is offering a boot unlocks and regular sim unlocks with GSM models. Not sure if it will work with the CDMA model.
Insights?
He said he can unlock Verizon locked Plays as well.
He just said on the 12th page post of his unlocking forum that the GSM baseband isnt supported.

Hello,
I am still wondering if the root process allows the XPERIA PLAY from Verizon (cdma version) to be used as a World phone (by putting a sim card in the slot). I'd appreciate if you guys can tell me if this is possible.
Thank you
I think @netorino is right, baseband doesnt allow gsm networks."
I am just asking and double making sure cause I kept seeing people using the word "unlocked". And I know unlocked has multiple meanings. (boot, sim,ect)
I come from HD2 XDA.

Don't quote me...but I think you would be better off getting the AT&T play as its gsm as is T-mob, while Verizon is cdma.

Quick answer? NO, absolutely not.
Longer answer?
Basically the SIM Slot seems to be physically uncoupled from the chassis. Further, the chipset that would be running the GSM is replaced with one for the CDMA. Whether it can function as both is a question, but the chip is actually different (from my teardown to look, the chip numbering is different from the tech/repair manuals).
I would, in general, assume that no phone that is on Verizon (unless it specifically says "World phone" or "World Edition") can be used on T-Mobile. CDMA vs GSM silliness. Different frequencies, different methods, different technologies.
So while the bootloader unlcok could work for the CDMA model, the SIM-unlock wouldn't.
Interestingly enough, there are still traces of the GSM code in the phone's diagnostic menus though.
i have a friend that has a phone repair shop in my hometown. i called him when i found a play that is cdma thru verizon. it is a world phone and has a sim card slot. he said that as long as its a world phone version it can be unlocked for gsm use in the united states. idk im getting one tonight and im gonna tinker with it and once i get it all going i will let everyone know on here if it can in fact be unlocked for gsm use in the US.
Well???

well turns out that the phone ended up not having a sim card slot and the person that i was supposed to purchase it from had no clue about anything. i did not end up buying this device. sorry!!!!
This was stated years ago, the R800x has a sim card slot but it is turned off on a hardware level. It is a non-functioning sim slot.

Unlock Verizon Nexus for T-Mobile?

So I'm thinking of buying a Verizon Galaxy Nexus.
I know it has a sim tray so i'm wondering if it can be unlocked for T-Mobile.
Any help would be appreciated.

Sim tray maybe but the vzw one is cdma and the GSM one is...well..GSM.
Different technologies! Not compatible.
I have the Verizon phone and yes it does have a SIM card but it uses different radios. Verizon uses CDMA/LTE and T-Mobile uses GSM so you can put whatever SIM card you want in there but since it uses different radios it won't physically be able to talk to T-Mobile (or any GSM carrier's towers)
btw, what happen if you travel away USA in a country without CDMA?.
At least, the CDMA iPhone have a simcard tray but it's locked until your operator wants.

Starting with Verizon's 4G LTE phones they all require SIM cards. They were also used in 3G global phones (my old blackberry and droid pro had them) but the CDMA Galaxy Nexus isn't global so you'd just SOL.
well.
nope. it won't work cause it's not CDMA...

@[email protected] can't believe people are asking this question. The phone has been out for over 3 months now.
Besides, the SIM card slot is specifically for LTE... as in, the SIM card is an LTE SIM card. LTE, not HSPA+.
I can only think, because the AT&T (HSPA+) model would be more prolific among sellers, that you'll have a better time finding a better price than a Verizon (LTE) one.

Then you have no service. Grab a cheap GSM phone and pre-paid SIM.
Try the yellow or the sky blue Galaxy Nexus. Those ones will work on both Verizon and T-Mobile.
Thats odd cause I have done it before

Back when verizon did both GSM and CDMA I had a verizon phone that I got to work on tmobile. I think it might have been a windows phone, honestly it was a while ago. I had to pay for a network unlock code and patch a radio or something....anyway, just wanted to say that it is in fact possible. My phone did brick in about two months, but that might have been from getting it wet...anyway...Good luck!

Total non sequitur. The phone in question must have been an old "world phone". The Verizon Galaxy Nexus never had any GSM radio whatsoever.
Also you bumped a 2 year old thread.

For the CDMA GNex you would need either a CDMA or neutral carrier/MVNO (such as StraightTalk, Tracfone, etc.). I have a CDMA ex-VZW GNex (now running Unlegacy-Android 7.1) that I am taking to Tracfone (replacing a Tracfone feature phone) because Tracfone uses a mix of carrier towers (depending on location, either T-Mobile or VZW). My current feature phone uses T-Mobile towers - because I am bringing a CDMA phone under BYOP, I have to ask the carrier (Tracfone, in this case) to create a custom SIM Kit for the brought phone, and thus have to communicate the IMEI and MEID of the incoming phone (this information is in the phone under Settings). Yes - this also applies to lifeline feature phones supplied by Tracfone/Safelink (if Safelink supplied the phone, Tracfone is your MVNO). If you want a GSM version of the Galaxy Nexus, you would want the maguro (the Galaxy Nexus in AT&T Mobility or T-Mobile guise); because GSM is more popular overseas, they tend to get exported compared to CDMA or W-CDMA (Verizon or Sprint, respectively).

SIM Card

I am going out of the country to Mexico. I have never used an international sim card with my phone. Can I use one in Mexico. My phone is Unlocked and rooted. It is Verizon CDMA.
I highly doubt it for the simple fact its cdma. Most countries use GSM. I may be mistaken but I'd check with Verizon just to be 100% sure

That is what I thought just wanted to confirm. My phone is not international but I thought it would be with a different international sim card

The reason you're phone is not "international" is because the radio chip only communicates via certain frequencies. It is a function of the hardware that is physically soldered to the logic board. Changing a sim doesn't make any phone international. Whether or not the phone has a chip that supports the frequencies that the SIM is trying to use is what determines if you'll get service.
Also, Verizon only uses SIM cards for LTE service, not the phone. If you ever get your hands on an iPhone 4 or 4S that is on Verizon, take the SIM card out. The phone will still work fine. It doesn't even use the SIM card (because 4s and 4S's don't have LTE).
You posted this in the wrong section dude
Went ahead and reported it, asking it to be moved.
No worries though. It happens!

SM-N976V 5G on Telus network

I purchased this model of phone through Best Buys online retailer. They misadvertised the phone model and sent me this SM-N976V.
The phone seems to work fine aside from the fact that it doesn't show the 5G network here. I confirmed with Telus that their network is operational.
Does anyone know why it isn't working with this phone or if there's some sort of workaround?
I Googled that model. It came up Verizon. It also came up that a ton of people had issues with it and the 5G network. Something about that phone came out in 2019 and it isn't compatible with the new 5G network. You might want to talk to tech support.

That's the problem, it's a Verizon model. The phone was advertised as just a SM-N976 and they just sent me this Verizon model instead.
I am wondering if there's some way to remove the Verizon software to make it just a plain universal model.

I have yet to find anything to open a Verizon phone to make it universal. Verizon is on the CDMA network and say AT&T is on the GSM network. So I don't know if it's in the phone or sim card that makes the phone universal.

Look into changing the CSC to GCF instead of VZW and (for my n976v with one ui 3.1 &hiddenmenu) it took all of verizons bloat off apon sim change.
