[Q] Galaxy S5 Active on T-Mobile

T-Mobile uses the 1700MHz and 2100MHz frequencies for 4G LTE data, and the Galaxy S5 Active supports 1700 and 2100, according to GSMArena.
1) Why then is the phone listed everywhere as "For AT&T"?
2) If I buy an S5 Active without a contract, how will data work on T-Mobile? 3G? 4G? 4G LTE?

Any given S5 model has the hardware capability to operate on all of the GSM and LTE bands. But Samsung can sell more phones, and carriers can deter you from jumping ship too readily by marketing lots of different S5 models that have various incompatibilities.
The S5 Active or SM-G870ADGEATT is a ruggedized variant, exclusive to ATT. So why is it said to be for ATT? Marketing.
As to compatibility with TMobile, assuming that you SIM unlock it, it can operate on most of the TMB bands. But again ATT has put a lot of thought into how to discourage you from moving to a different carrier. To wit, they have omitted support for TMB's 3G 1700 and LTE band 8.
You'd have to find out how widely TMB uses those bands to know if that would be a large impact on data use or not.

There was a rumor posted 2 months ago on the Android Community that a T-Mobile version of the Galaxy S5 Active (model SM-G870T vs the AT&T model SM-G870A) would be out in late July. Here's a link.
http://androidcommunity.com/samsung-galaxy-s5-active-availability-leaks-out-20140529/
Obviously it's late July now and we haven't seen it but I'm wondering if AT&T got an exclusive on the Galaxy S5 Active for a few months and T-Mobile will release it after the exclusivity period expires.

Sorry to dredge up an old topic, however you mentioned that the S5 active has the hardware capability to support all TMB bands, 1700 included, but then say "To wit, they have omitted support for TMB'S 3G 1700 and LTE band 8". Does this just mean the stock AT&T ROM is the only limiting factor? So, were I to flash the AT&T stock ROM and install a Tmobile ROM for example I could then utilize ALL of Tmobile ' 3G and LTE bands? (And wifi calling to boot).
Thanks

S5 Active is pretty limited on Tmobile network

I NEED to do something with my S5 Active to get it working better on Tmobile. I love the S5A... its a perfect phone for me. Not too big, but big enough. Rugged, waterproof, good camera, uSD card, etc. Without WiFi Calling and support for all of Tmo's freq & channels, its severely limiting.
I'd pay someone to help me convert my phone to Tmobiles stock S5 5.1.1 ROM and baseband radio firmware.
Help!

Also having the same problem with an unlocked S5 Active originally setup for AT&T. It uses the EDGE network only.
Has anyone successfully modified the phone to utilize the TMB 1700 band or the LTE band 8 as mentioned in this post? (either through ROM upgrade or other)?

I love the S5 Active, but using it with T-Mobile is such a hassle. I have the $30/mo. prepaid plan that includes unlimited text and data, so I'm not changing carriers anytime soon, but I have to buy new phones outright. When I bought this for myself last December, I saw it was compatible with T-Mobile so I pulled the trigger - a mistake in retrospect.
I'm from a large metro-area but T-Mobile's 4G signal is nearly impossible to get with this phone. Aside from never being able to connect to the internet when out of my apartment, sending/receiving MMS texts are a chore. I also discovered today that my android OS with this phone hasn't updated itself since I bought it - it's still running 4.4.2 and when I try to check for updates to Android through my device settings, it tells me AT&T has no new available updates at this time (there have in fact been 3 new updates AT&T released during this time).
So while I really love the phone, I'm going to have to sell it and look for a new device that's actually compatible with T-Mobile's network.

The Fix
I would go in the VPN settings and manually reset the ports and frequencies the phone reads and when it reads the T-Mobile sim card that it reads upon boot up.
Now, I'm running similar set up with Samsung Galaxy S4 & S5 (At&T variants), it seems like it works, have tried it on friend's S5 Active and it works perfectly.
The only problem is that you won't get to enjoy the freedom of wifi calling even though u have T-Mobile sim card and service, But at least u will be guaranteed to use T-Mobile 4G LTE speed and signals. Occassionally, T-Mobile will blackout or a region without T-Mobile and automatically the phone will roam with no charge and use AT&T signals for up to 15 minutes or depending to circumstances of the situation.

To get the At&T updates, I would advise you to go to Ebay and buy a prepaid At&t sim card for the phone and use it temporarily just to update it all the up to 5.1 Android OS and your phone will be running up to date. (cost anywhere from $3.99 to $15.99)

I got the AT&T updates by going into a Best Buy where they have a Samsung Experience center, took about 10 minutes but they updated my phone. I'll have to look into the VPN settings and see if there's anything I can do, but after purchasing the phone online I did have the folks at a T-Mobile store set the phone up for me so I would've figured they would have set it up proper.

I have a S5 Active and I was considering making the jump to TMo, but I really would like the functionality of the wi-fi calling and text, since I work in a hospital and can get no reception or texts. Pardon me if this is a dumb question as I have no experience in jumping carriers with rooted phones, but would I get the features if I had the TMo sim, applied the TMo APN's, flashed a TMo stock or custom rom that has the features baked in? Would I just flash the 870a kernel to make it work? Anybody that has any ideas, I would love to hear them. Thanks

I'm on T-Mobile, would it be worth getting the S5 Active? I currently have the S4 Active.

US Cellular Note 4 SIM Unlocking

Hey all,
I recently got my Note 4 through US Cellular SIM unlocked and when I insert another SIM from AT&T or Tmobile, the phone accepts the SIM but there isn't any setting to change the phone to global mode in the network settings area, nor is there a way to change APNs. I cannot place calls on either Tmobile or AT&T with it, which I find odd since the phone doesn't reject the SIM. Does this version not have support for GSM bands or is it something to do with US Cellular's software that prevents it from connecting to United States GSM carriers? Is there a hidden setting that I need to get into to enable GSM use? Thanks all!

Old thread but bumpin, any news on this?

I also have bought a US Cellular Note Edge (not arrived yet) to use it in European GSM Networks. Phone was really cheap, so i thought i'll give it a try. Anyone have news on how to unlock GSM capabilities on this ? Maybe with a Rom from a GSM Edge ?

I am having the same problem

I recently spent some time on the phone with the executive assistant to the president uscellular and well I had no success in getting my phone unlocked if I understand correctly the phone is cable of gsm also. If anyone would like I can give you the number 4 this lady name Karen and you can bring her directly. I also spoke with several members of the presidents executive Support technical service and they all indicated that the machine would have to be taking it into the store to be unlocked. the weird thing was that the machine is not blacklisted, stolen nor gained in any ill gotten way but yet all with one accord further said that it would be refuse for unlocking without giving any good reason. I understand the company was sued in court and lost the battle to not unlock their phones and this seems to not affect them only one to one basis. I will find a solution to this and I will share it. I would be grateful for any help in doing meanwhile.

Hey, everybody. I hope I'm able to help... and in turn, I hope someone is able to help me.
Supposedly... newer Qualcomm-powered Android phones are inherently capable of connecting to any CDMA or GSM network. However, the different bands are enabled/disabled per the carrier's specifications. For instance, I'm a Verizon customer, and I connect to bands 4 and 13 for LTE service. However, US Cellular devices do not have band 13 enabled by default.
All hope is not yet lost, though. There is a thread (which has since been closed due to trolling/bickering) that details a method to flash the Qualcomm chip to enable/disable bands as needed. See here: http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059 According to the information there... it seems that I'd be able to flash the CPU chip to enable band 13, and then I'd have support for all 1x / 2G / 3G / LTE bands that I'd need for Verizon. Likewise for T-Mo, Sprint, ATT, etc.
Now for my problem...
I have recently purchased a USC Note 4 (N910R4) from Amazon, though it was listed as a N910F, International Edition. It was listed as having been unlocked for use on any CDMA network. Unfortunately, the phone does not recognize my Verizon SIM, Verizon couldn't give me any information about the device, and a US Cellular support chat representative said I'd have to visit a store to check if the phone is actually unlocked. The closes USC store is several hours away in another state. The phone came with a USC SIM still in it... and it recognizes that SIM without a problem. I can't make phone calls, though... and no mobile data, either.
I had intended to use the International Version (N910F) and enable the correct bands per the thread above... and then activate the phone on my Verizon account... but the USC version should be close enough in band support that I'd be able to at least activate the phone. The USC phone supports band 4 LTE, and I get band 4 service where I'm sitting right now. If not that, the 2G and 3G band support are identical, I believe. So, I'm just doubtful that I'll be able to activate the phone just yet.
Can anyone shed light on how to verify that my new phone is actually carrier/SIM unlocked? I was hoping I'd be able to get someone to query a database of unlocked MEIDs, but for some reason, I am supposed to go to a store. I can't even call.
Any help is appreciated.

I share all your concerns sir. I too have not learned yet how to determine if USC nope for exactly carrier locked or no but I am of the firmest belief based on what I've learned from USC at various levels up to the Presidents executive team that it is indeed carrier locked. I cannot answer for yours then I believe that all under phones come in one of the two varieties and I am convinced even after the court ruling against them that they I have no intent to unlock a phone by less than forcesure. Furthermore I have no confidence that the store they may send you to has any unlocking abilities. According to the executive team that does this work in reality you must in the machine into them and prove its worthwhile to be unlocked. In my case well they cannot prove there is any malfeasance, they still choose to err on the side of caution and refuse to accept any proof then I have of the machine purchased new complete and clean but from a second party. They furthermore refuse to contact the locals that originally sold the phone and truthfully are the first corporation that ever more me so thin that I chose to unlock the bang bang myself. I remain as giddy as a schoolboy hoping to hear more good news from this post. I'm confident then I currently have the knowledge to fix the phone but do not currently have the time. I will happily update I'll with my success be crying the Blues at my failure soon.

Any updates, guys? Did flashing the ROM to allow access to additional channels work for anyone? Thinking of buying a USC Note 4 and then trying to unlock it for GSM usage.

Any news on unlocking or using on GSM networks? thx

Has anyone got any further with this? I've just bought a US cellular note 4 and my APN settings are greyed out. I'm assuming that US cellular will be difficult to deal with to get the phone unlocked especially if it has been bought from a third party. Has anyone had any luck with getting there's unlocked?

Hi!i set my Note Edge to say on Network mode:GSM/WCDMA/LTE but i can't place calls etc...has anyone an idea to make it work?

use z3x box to unlock it

To whom might be concern;
Make things short, NO, you cant use USC Note 4 on any US carrier if u look at the spec. The phone support only some GSM850 and FDD LTE band 5 (850mzh). And att/tmobile 2g voice is on gsm1700/2100 and LTE band is not match....... So that being said you are buying note 4 as Samsung Player and only good with USC and somewhat Verizon(need to hack for it to work, and stillike not all feature will work). Hope answer most you guy question

I've still got the USC Note 4. My son uses it on wifi and to watch videos that we load to local storage. In other words... no sim card installed.
If I manually update the phone to 6.0.1... what will I gain being that I'm a Verizon customer? Is the only difference that 1 band of LTE will be inaccessible? Would it actually start working for calls and some data with a verizon sim?
The whole "reprogram other-carrier Qualcomm phones to work on Verizon's bands" is frequently debunked as chasing a unicorn in the verizon forums.
Further... is the same applicable to newer phones? Could I get a newer (note 5/7) USC phone with android 6.x+ to work with verizon? (Unlocked bootloader would be my only reason to try)
Thanks!

Verizon and sprint are the only reason USA doesn't have the faster exynos processor.

I'm also interested in this. I'm thinking of buying a G935F so I can root and have complete control over the recovery and ROMs.
I assumed the international (global) variant would support everything. My Galaxy S5 works everywhere including the US and also drops to 3G if necessary on Verizon. The ultimate question is, if I buy a G935F, can I make/receive calls, texts/mms, and get data using a Verizon SIM card? If I'm in a fringe area and it drops 4G, what will happen? Will it just have no service? I have to think it would support 3G/2G. If a person from Europe comes to the US with the G935F and uses a verizon SIM or is in a verizon only area, they would be screwed.
Again, I would think it should just work, no?

It will not work on Verizon because
1. Verizon relies on using the outdated CDMA standard so you can't connect to their "3G" network.
2. Verizon uses non standard version of the VoLTE IMS (so does T-Mobile it seems), so you can't place calls over LTE even if you flash a VoLTE enabled firmware on your GS7
3. Verizon as a carrier is a control freak that doesn't let its costumers use devices that have not been "approved" by their services, therefore, your devices' IMEI have to be white-listed in order to connect to their network.

Already started the process of moving to AT&T...waiting on my work to confirm it. I hope Verizon reads this. It would have been some much simpler if they just unlocked their bootloader and didn't put a ton of crap (bloat) on their stock ROM...then they would have retained this customer.

I was considering the G935FD (dual sim) since my personal phone is AT&T and my work phone is Verizon. I want to consolidate to a single phone. Honestly I only need Verizon for calls and text, not even data, since my AT&T is unlimited. Looks like the international S7 Edge support Verizon's primary LTE band 13 which would technically work for data, but won't connect to their CDMA calling network according to mathieulh.. Now here's the kicker.. the new ZTE Axon 7 is supposedly compatible with Sprint and Verizon, AND it's a dual SIM phone. I know Verizon has to give the final "okay" to have a device activate on their network, but looking at the specs between the Axon 7 and the G935FD (dual sim S7 Edge) on GSMArena, there are essentially NO DIFFERENCES between 2G/3G/4G(LTE) bands between the two devices. The only difference I really see is Cat 6 LTE (300/50Mbps) on the Axon 7 and Cat 9 LTE (450/50Mbps) on the S7 Edge.
Can anyone clear this up? ZTE is literally saying their Axon 7 will work on Verizon, with essentially the same network specs as the S7 Edge international... there MUST be some major defining issue with using the Exynos vs Qualcomm processor when it comes to CDMA connectivity, but I still can't see a spec difference online.

G930f won't work on Verizon
Hey guys so I see this last post is from almost 3 years ago but I like the s7 and I have verizon. I don't like the Verizon variant of the s7 and wanted to try this one, the g930f because it had the same bands for LTE that verizon uses. I thought I could just use Google voice and make calls with data. I've been messing around with it for a few days now and I'm using a pre-registered sim from a Motorola that I bought from Verizon. I cannot get it to register even with data alone. I've tried removing all AP names and then creating several different AP names using Verizon settings. It's a no-go. I'm getting the g930u.
Thank you for reading. Maybe you know a workaround?

Dual CDMA sims?

I was curious if anyone had tried dual CDMA carriers on their dual sim G4s. My understanding is that for 3G cdma voice the device itself is registered as opposed to a 3G GSM which registers the sim, so only one CDMA service could be active at a time. Changing to another CDMA carrier would mean going through Verizon's or Sprints's activation process each time you wanted to change to a different sim (this was my experience with a 3 sim adapter). I'd love to hear someone more knowledgeable chime in on this subject and provide some feedback on whether or not this is how it would work with a dual sim moto G4.
I'd love to have dual CDMA sims because I have free service with ringplus (Sprint MVNO) but it's spotty in rural areas, whereas Verizon has the most solid signal in the remotest regions.....however I think it's a pipedream. I am aware that you can do a CDMA LTE sim switch and get data without a problem (I'v done this with a triple sim adapter), it's voice and text that I'm interested in being able to switch to, without having to go through the activation process. And because I need this voice and data in remote areas without LTE, VOLTE isn't an option.
I hope that isn't too convoluted or arcane a question, I realize it's not a common scenario. But with the Moto 4G being carrier friendly to all the north american providers (GSM and CDMA) and having a dual sim slot, it's the first plausible solution to what I'd like to achieve.

Unfortunately, the only G4 models that have CDMA are the US models (XT1644 G4+, XT1625 G4, XT1607 G4 Play, XT1609 G4 Play for Verizon Prepaid), and the US models are only available in single-SIM format.
From what I've been gathering, there are no dual-SIM CDMA phones that fully work with US carriers available yet. The OnePlus 3 comes sorta close, it's dual-SIM and has CDMA Band 0, which Verizon uses in most markets, but at the moment it either works in 1x/EVDO mode for calls/text, or LTE mode for data. However, it's lacking CDMA Band 1 (Verizon & Sprint) and CDMA Band 10 (Sprint), so it's not ideal. It's also lacking Verizon's main LTE Band 13, and all of Sprint's LTE bands.
Slightly good news, though. The upcoming ZTE Axon 7 is dual-SIM and FCC testing indicates that it fully supports all US carriers, including all Verizon and Sprint CDMA bands.

I'll keep an eye on it.
Would the concept work the way I described in the first post though? I'm really curious if the phone would require sprint or verizon activation when switching cdma sims. I don't have a great deal of experience, simply my results with a multisim adapter. I was unable to test the adapter with a verizon and sprint capable phone (like a nexus 6) but tested it with an Verizon samsung s5 using gsm sims and a verizon LTE sim. The gsm sims (various at&t and t-mobile MVNO) were of course no problem, but switching to (or back to) a verizon LTE sim required teh verizon activation process (but not for data, as the LTE was active without activation).
Is it possible to have a dual sim (or even single sim) phone that supports both carriers (Verizon and Sprint) that could switch back and forth, or is the activation process simply inherreient with the way the devices imei's are registered on CDMA networks, and will always be required. For me going through the activation process for Verizon or Sprint when switching sims would simply preclude any practical usefulness with a dual sim cdma capable phone (although it would still have value as a dual sim with a cdma and a gsm sim).
Sorry for the late reply xtermmin and thanks for the info.

I can't speak for Sprint, as I have Verizon, but I do know that they're more restrictive than Verizon.
On Verizon, the only current restriction is a whitelist when you try to activate a SIM for the first time. You have to use a device that's in Verizon's "activation database", typically Verizon-branded devices, iPhones 6 and up, the Moto X Pure, and (at some point, if not now) the Moto G4 lineup. Once you have an activated SIM, you can stick it into any compatible device (be it from Verizon, another provider's phone, or even an unlocked phone that doesn't officially work on Verizon) and you should be good to go.
For example, I've been using my same Verizon SIM that I got with the HTC Thunderbolt (when it launched in March 2011) in numerous other phones (Verizon phones, US Cellular phones, unlocked phones, even some GSM/LTE-only phones) with no need to contact Verizon or use the website or anything. I've been able to just pop in the SIM, adjust the connection method on the phone if needed, and go.
As for your experience with using a dual-SIM adapter on the Verizon GS5, it might be due to the phone going into "GSM/LTE" mode when you insert a ATT/TMO SIM, but not switching to "CDMA/LTE" mode when you switch to your Verizon SIM (thereby only connecting in LTE mode). Might want to try setting it to Global mode (GSM/CDMA/LTE). The Verizon version probably wasn't tested for dual-SIM use, so it might just be the OS not knowing to switch to the other mode, or it might be an issue with the adapter itself.
Regarding an actual dual-SIM device with both SIMs being CDMA, I'm unsure if it causes any issues, as there's been no phone with that ability released yet (technically, someone can try dual Verizon SIMs in the OP3, but the CDMA implementation on that phone looks to be pretty half-assed, so I wouldn't use it as a baseline). Guess it depends on how the SIM slots are setup (if they share the same IMEI, or if they have different IMEIs for the two slots). If they're the same IMEI, I can see there potentially being issues, but if they're different (which should be the case for any modern name-brand flagship), there shouldn't be.
We'll know more once the Axon 7 releases. Unfortunately, ZTE has said that CDMA support will be coming in a software update later, but at least the phone is physically banded for CDMA, so we won't know for sure until then.

Actually the xt1644 have dual sim slots , one is hidden open the phone and you will find it

definitive FACTS on all s8 variants

I bought a Verizon SM-G950UZKAVZW direct from Samsung. I thought that I was buying a phone that I could take to any carrier. I'm hearing that might not be true. Does anyone have definitive, confirmed specs ie supported radio bands on all of the carrier variants as well as the upcoming intl version? Also I heard other reports that the hardware is identical and it's firmware that is limiting the phones. Not sure if that is true either. Samsung was absolutely not helpful.
Bottom line I need to know:
1 if I keep the SM-G950UZKAVZW, will I be able to use it with other carrier networks?
2 if I can use the SM-G950UZKAVZW with other carriers, what actions (if any) would I need to take to do that? (Other than swapping a sim card)
3 would the phone I currently possess be limited in any way if I were to use it with other carriers? (Limited is defined here as "performing differently in contrast to that carriers native S8 model variant") if so, specifically how would it be limited?
4 if I were to purchase an unlocked international model once it becomes available, would that phone be limited in any way when used on any US carrier? (Limited is again defined here as "performing differently in contrast to that carriers native S8 model variant") if so, specifically how?
If you aren't sure, please don't reply. There's plenty of people documenting their best guess already. I'm looking for the straight story.
Thanks for reading!

All of Verizon phones are Sim card unlocked and since there is really only 1 version of the S8/S8+ in the US (with different model #'s corresponding to the different carriers) using the phone on another carriers network is not going to be an issue. All you need to do is insert the sim card in.
http://www.gottabemobile.com/how-to-unlock-the-galaxy-s8/
As a quick note, if you have a Verizon Galaxy S8 congratulations. Your phone is already unlocked. Verizon Wireless no longer locks phones, regardless of what you might hear from friends or family. Simply drop a T-Mobile or AT&T SIM card in a Verizon model and it works. It may require manually configuring the APN settings though, so keep that in mind.

The ONLY exception that might be would be Sprint since they are CDMA as well, but who really wants to go from Verizon to Sprint?????
All 4 Major US(and subsequent sub carriers) are receiving the same version of the phone(meaning same internals). From my understanding, inserting the carriers Sim card into the verizon phone just means you start going at that point and have access to all the carriers bands
If you got an international version, it most likely would be powered by an Exynos CPU vs the Snapdragon 835 so there would be some performance differences (typically Exynos models perform marginally better based on previous history)
If you're looking for a US unlocked model - wait until next month
http://www.theverge.com/circuitbrea...-unlocked-galaxy-s8-plus-pricing-release-date

I appreciate your clear response! Would it be accurate to say that I will have just as much freedom to hop from one carrier to another using the phone I have, as opposed to purchasing the upcoming US unlocked variant?
Also, I have heard the same thing about the hardware, that all of the carrier variants are the same physical model. But some folks, including the Samsung tech support rep I spoke to (unfortunately that probably doesn't mean a whole lot) seem to think that the carrier firmware is limiting the radio bands. Do you know this to be false?

I have the Verizon version and works fine on Tmo out of the box. Have to use Verizon update software through Windows though. OTA's will never come through.

I am using Verizon GS8 on att, it works but I only get HSPA mostly. No LTE, so band is definitely capped by firmware.
I didn't have any issue receiving ota with att sim in vzw gs8

I saw a review that said the s8 gets locked to the first carrier sim it accepts. Can someone confirm swapping sims of different carriers works?

Have you tried going into the network band menu and locking it to one of the AT&T LTE bands?
This still works on the S8 (found this on the S7 and used it to lock my S7 to band 4 for Tmobile)

You'll need to wait unti the official AT&T rom is available from Smasung and then you should be able to flash it via ODIN onto the phone and get all the AT&T carrier bands

Once it becomes available? You can buy Exynos right now from other countries. Clove in UK will region unlock the phone before shipping to you in the U.S. What needs to become available?
Don't confuse the "unlocked" S8 Samsung will sell here in the U.S. in a month or so with the Exynos international variant. The "unlocked" S8 coming to the U.S. is still the bootloader locked Snapdragon version, just without carrier branding. It will be carrier unlocked but not bootloader unlocked. If you care about rooting, TWRP, ROMs, etc Exynos is what you want.

NO, except if you are on CDMA-handicapped Sprint or Verizon. If you use Sprint or Verizon be aware Exynos doesn't have 3G CDMA bands to fall back on if you can't get LTE. For AT&T or T-Mobile, YES it has all the LTE/HSPA/GSM bands.
The "international" Exynos variant can be bootloader unlocked, rooted, etc. so tons of advantages. While it has Verizon LTE bands, there's no CDMA. This means you really need Verizon VoLTE to work and I don't have the answer to that. And if you can't get LTE signal on mobile network, you won't have any signal due to no CDMA fallback. Again, only an issue because of CDMA if you stay on Verizon instead of using AT&T or T-mobile (or their network affiliates). You seem like you want to switch to another carrier? So, go ahead and do so!

Yeah I screwed up. I did confuse them.
I'm not interested in all that rooting stuff I just want a phone that pretty much works anywhere I want to take it and if it's slower on one network than another I wanna know what I'm getting myself into.

Hey guys
I'm from Brazil and I wanna buy the Verizon's S8 but I'm afraid about the 4G.
I saw that this model has the Brazil LTE frequencies, but I read here that Verizon capped the band from the firmware.
Somebody knows if I could flash via ODIN the unlocked rom that will come with the unlocked version in USA and so get the LTE free to use in any place?
I don't want to assume the risk to have a top mobile phone but don't be able to use 4G.
Thank you very much guys

Hey mredamon. Did you ever get a clear response here or somewhere else about this?
