US Galaxy Tab - is it usable outside of US? - Galaxy Tab General

Hi,
I am in US this week, and found out that a non-contract Galaxy Tab cost only $599 (sprint and verizon).
While I understand that most phones in US are sold as locked, I am not sure about Galaxy Tab. I asked the best buy staff, he told me if I don't buy it with a contract, it'll be a WIFI-only tab (so I thought it's a locked) but he went further to say because Galaxy Tab has no sim slot.
Is it true? If not, (as I thought Galaxy Tab will have a sim slot) does a international sim card work on the US-based Galaxy Tab?
I suspect it's essentially a locked tab (that couldn't accept other sim card except the respective telco one even with a sim slot), otherwise, $599 is really cheap. but I need confirmation.

The Sprint and Verizon Tabs have no SIM slot as they are CDMA devices. The T-Mobile and AT&T Tabs do, they are GSM/UMTS (though on different bands)
Both will work in on GSM/HSPA/UMTS networks though neither has voice capability built in.
You can flash international firmware to add this to the AT&T version with little effort, and it will be a full quad band for voice and EDGE data. T-Mobile is more problematic to flash.
All are SIM locked, but unlocking them is really quite trivial.
Best bet is to buy the AT&T version for $650.

ok, so it looks like AT&T is a safer bet indeed. California tax is a killer, end up I would only save $100 plus.

[Q] How to use SIM from phone in tab 7.7

I have the SGNexus from verizon with LTE and the phone has a uSIM card in it. I just picked up the SGTab 7.7 last night but did not activate (bought outright).
So, I may wish to use the uSIM card in the tab but am aware that there are things the carriers look for to prevent this and I'd like to prevent them from screwing me. Again, I don't expect to do this much but would like the OPTION of doing so.
What do I need to do and not do to use the uSIM from my SGNexus in my SGTab 7.7?
Thanks,
Brian
So this is the VZW Tab 7.7? I was assuming they would bake the SIM into the tab to prevent exactly what you want to do, but I haven't actually seen one yet. In the P6800, there is a SIM slot along the same side as the microSD slot--does your tab have a SIM slot? If not, you won't be able to switch for sure. If there is a full-size SIM slot, you just need an adapter, which is easy to get or make (can probably get one for like $1 on ebay).
Also, I wouldn't expect VZW to allow your phone SIM to work on a tablet in any case. Even if you could put the SIM in, VZW will know from the IMEI that you are using a tablet and (I assume) force you to change plans or whatever.

At 5:10 of this silly unboxing video the SIM slot is in view.
http://www.androidauthority.com/verizon-samsung-galaxy-tab-7-7-lte-unboxing-59081/
I didn't think they would have an open SIM slot on the Verizon unit either, but maybe it has the capability of being unlocked?

Interesting. So yeah, OP: go get a SIM adapter, plug in your SIM, and see what Verizon says to you! Good luck.
Before I go that route I'd like to make sure I avoid anything that would give me away. I'm not sure that's possible but since there are a lot of smart folks on this board I'll wait a bit to give it a shot.
I think the thing I'd most likely use it for is in-car navigation on the longer trips. I have the Verizon SGNexus with LTE and I have the hotspot option so I could use it in that mode to drive the navigation on the tab so maybe swapping in the SIM wouldn't be that big a deal.
Still, it would be nice to have the option...

It's not possible to hide the fact that you're using a tab 7.7 from Verizon unless you're willing to try to change your IMEI (and messing with /efs is pretty dangerous). I'm not saying it's totally impossible, but it'd be difficult at the very least. As you say, there are a lot of smart people here, so maybe someone will work out a way--but I wouldn't hold my breath. Still, no way to know if it'll work unless you try it.
Personally, I bought the wifi version because tethering to a phone is easy and a lot cheaper--save $100 at the start, plus no second data plan at absurd US carriers' prices. I think many of the people who bought the international 3G version were thinking the same as you--they can swap their phone SIM in if they want. However, the unlocked version identifies on the network just like any phone, unlike the Verzion version, which is locked down by Verizon and doesn't even ship with phone software.
I toyed with the idea of importing a wifi only version but decided I didn't want to lose the next door support if I have a problem so I went with Verizon and so far as I can tell they will only offer the LTE version. If putting my phone SIM in it is not going to work or work for long then it will be just a wifi only version albeit about $100 more expensive. I think I could reclaim some of the difference on resell though...
I really hope ICS is coming soon as I don't much like HC...

Forgive my ignorance guys but what is this verizon with LTE?
I am not in the U.S., for me the P6800 model works with a normal GSM SIM or 3G SIM out of the box.

Verizon is a US carrier that does not use GSM. The Verizon version of the GT7.7 has different hardware then the standard GT7.7 and it is unclear if you can just swap the Verizon LTE sim from one Verizon device to their GT7.7 and have full functionality.

LTE is the reason why a simcard is utilized. I'm pretty certain that rest of the cdma/evd0 doesn't utilize the simcard

purchasing International version/shipping

Just curious of anyone who bought the GN2 internationally, and is having it shipped to the US. I keep seeing "SIM Free" versions popping up on various amazon... i was under the impression most carriers was still using SIM's.
Anyone know their compatible bands and if they work with ATT's LTE? thanks :cyclops:

"Sim Free" does not mean that it's not using a SIM card. It means that it's not carrier locked. The international version will not work with ATT's LTE. You can get HSPA+ with ATT.
The U.S. including ATT will get their version about a month later. That will work with the LTE. Samsung has an event on october 24th in new york. It's likely that the U.S. version will be launched then. http://www.cnet.com/8301-17918_1-57521523-85/samsung-teases-galaxy-note-2-launch-party-on-oct-24/
The Wiki details the bands for both the 7100 and the 7105 variants
Here in the UK - "Sim Free" means that the phone is supplied without a SIM card is not "locked" to any particular carrier and only has Samsung "bloatware/extras" not the carriers as well.
The 7100 takes a standard Micro Sim (sane as the Samsung Galaxy S3) rsther than the Mini-Sim

[Q] Prospective buyer, ?'s on the variant options

Hi everyone -
Have been on here quite frequently for my SGSIIE4GT, but it's been a while since I've posted. I'm in the market for a new phone, and I think I will be going with the Note 3. However, boy am I confused on which model is the right fit for me. I could really use some help and a little insight, as the reps at AT&T, TMO, VZN, and Samsung Live Chat haven't been able to answer my questions.
I'm currently with Sprint, and looking to leave. I would be using the Note 3 near San Francisco 90-95% of the time, but I do travel 6-7x/yr to Asia, Canada, UK, and South America. I'm pretty sure I will buy the phone on no contract and use with TMO, AT&T, Straight Talk, or AIO. I've been reading some issues with "region locks" though that scare me a bit, not sure if this is still an issue with the models sold in the US.
From what I can see, ATT, TMO, VZN, and Sprint all have their own "versions" of the phone. ATT and TMO obviously use the same cell tech (GSM), so I don't understand why they have different versions. The VZN and Sprint versions would run on CDMA, which as I understand, won't do me any good if I travel overseas due to no CDMA elsewhere. Then there's the int'l unlocked versions, and the Developer edition. But then I heard just yesterday that the VZN Note 3 works on GSM (somehow, haven't figured that out though).....is there a SIM card slot in that version? After all that, I guess what I'm looking for is this which I could use some insight on:
Want to use the phone:
-with LTE using ATT/TMO/ST/AIO/VZN here in the U.S.
-want to buy off contract
-do not want bloatware...so do I need to buy unlocked?
-need to have it functional still if I go out of the country and purchase a local SIM card (some people ask me exactly which service I use overseas, and I don't have an answer b/c I haven't done this yet, my Sprint phone didn't even give me the option)
Which model is appropriate for that type of use? I read on Amazon that TMO's version is the best one out there b/c the ATT model doesn't work on TMO, but TMO's works on TMO and ATT.....
Thanks so much for your time. Samsung has really confused me with this phone, and could really just use some suggestions. Thanks again!

Hope that helps a bit
The 9005 will work in all other countries pretty much.
In the US it might work on tmobile as stated above but I'm not sure about the others.

Thanks guys. I have seen the N9005 tossed around a few times as well. I think the constant question I keep having is I see this phone made with the SD800 or the Exynos chip....but not which models have which chipset. I found the 9005 on Negiri in 32gb and the SD800....but if it works on tmobile why wouldn't it work on ATT? I thought they run the exact same tech.....no?

Awesome news, thanks.
Do you know if the Note 3 Developer Edition for Verizon, which works on their LTE network, comes with a SIM card slot that I can utilize if I go overseas? Boy, that would be ideal. I checked out the manual (http://downloadcenter.samsung.com/co...ual_MI9_F5.pdf) and it shows a SIM slot for the phone, no?
I was told by one of the writers at Droid Life that the Verizon N3 can be used on GSM. I thought that was impossible.
I seriously apologize if these are elementary questions, I truly do appreciate any insight. Just don't want to make a huge financial mistake.

Thanks for the input guys/gals. Really appreciate it. I went to Best Buy after work last night and talked with the Samsung tech rep. Turns out, the VZN Note 3 comes factory unlocked (per FCC law), and it has a sim card slot so I can use it on GSM if I travel overseas. One and done. I already put my name on the backorder list for the developer edition from Samsung so I can be sure to have functionality to remove bloatware. Wouldn't it be cool if the Note 3 could just come with 4.3 and Samsung's additions, but not any of Verizon's garbage??? I know, pipe dream.

Whoa, so it's a good thing I didn't buy the DE Note 3 yet and just on backorder. Just read - Verizon doesn't allow 4G phones to go prepaid? That makes no sense, because then the DE Note 3 would then be nothing but a paperweight since it must be purchased at full price (meaning, you could only then use it prepaid, no?). I do value Verizon's network, but their prices are just absurd compared to competitors.
Is there any difference whatsoever between the TMO and AT&T variants of the Note 3? I can't seem to spot a single difference.

SM-G950UZSATMB - What!? Bootloader unlocked?

I see this BOGO offer direct on Samsung's website for Galaxy S8's. In the past, all Galaxy S phones were SM-G920T (T for T-Mobile) SM-G920V (V for Verizon, etc) and then Best Buy sold that piece of crap SIM unlocked SM-G920U that was bootloader LOCKED and couldn't do anything with it.
I'm trying to find out here if the Bootloader is locked on any variant of the Snapdragon 835 S8's, and which version I should get. T-Mobile has the same BOGO offer on the S8 in the form of a rebate as well, but I can't confirm anywhere the specific model number. I'm so jaded by the fact that T-Mobile left the bootloader locked on their S7 that I can't imagine them leaving it unlocked.
The G6 is also BOGO right now as well, but I don't know if that bootloader is unlocked like all my previous LG phones from T-Mo we're.
I'd really appreciate any kind of confirmed answers you might have!
Cheers!

All the carriers have "U" devices in the U.S. this year. The SIM you initialize the phone with is what carrier's features are added. A "U" from Samsung apparently doesn't take on the carrier whose SIM is used features and remains virgin. So "U" could be considered "universal" or "U.S." It's still a S-835 device which means "U" definitely doesn't mean unlocked bootloader.
I'm not an expert at all but I really doubt that ANY Samsung bootloader will ever be unlocked again. Pretty much after 2013 all bootloaders were locked [AFAIK] at least for the Galaxy series. I really like Samsung devices but my Galaxy Tab S (late 2014) isn't even going to get the Nougat upgrade - this actually pisses me off greatly.
When you see 'unlocked' concerning a phone/device it means CARRIER unlocked, not the bootloader. The 'unlocked' means that you can use it with any carrier that the device supports - so just about most of the carriers/providers in the entire world. Still not sure about this concerning CDMA (Verizon/Sprint) as some things may not work (different bands). Tried using GSM phones on CDMA a few years back and wasn't able to use 4G/LTE & also MMS.
Good luck.
EDIT:
Was typing this as BarryH_GEG replied to your question. Yes the letter following the model corresponds to the various carriers (Verizon, Cricket, Sprint, etc) and are also different for international versions.
EDIT2:
On another note I own a Galaxy S7 Edge (international) that has the Exynos processor that is unlocked. At the same time this is the only device I've never rooted because it works so well for me, no carrier bloatware. Also the only device I've ever purchased without a removable battery. Until the latest updates I was able to go 2 days without charging (not anymore unfortunately). The international S8/S8+ also use the Exynos processor so you might consider this option. However the cost will be high as it was for me when I purchased my GS7edge as you'll need to purchase it directly without any US discounts or such. I paid out just over $700 for my GS7edge directly, though at the same time my AT&T bill is much lower because of this.
I've researched the GS8+ international and it's looking to be around $800. Compared to trading in my GS7edge international for an unlocked US version I can get for $375 (with trade-in) if I do this within a month or so... I can probably get $400 for my GS7edge (since it's international) but how long will this take? If I only get $300 for it for a quick sale I'll still spend $500 for the new 8+ so is this worth it?
Only stating these issues so that you understand my thinking concerning an unlocked bootloader. These are [mostly, still SS stuff] bloatware free, have incredible power, etc, etc. I miss rooting my device but is it really worth it for the cost? I really want the international/Exynos S8+ but still not sure.
Let me know your thoughts, later.

Is my sprint S8 seriously locked to sprint FOREVER?!

Hi guys.. So I bought a Samsung Galaxy S8 from Best Buy Mobile last month. I had to use sprint because at&t (my fav. carrier) would not finance me on the phone. I was told if I paid off the phone I could switch carriers. So that's what I did. Sprint even unlocked it. Now people are telling me I can't use this certain phone on at&t, or even verizon because it is a cdma phone. No one told me this when buying the phone.
Is it true that I am stuck with sprint?! I have horrible coverage in my area and I can't even use the internet and such unless I'm on a wireless connection. What can I do? Please help!
Did you try putting in a non sprint sim?
If it is SIM unlocked, just flash the unlocked (G950U1) firmware on it.

If the Sprint unlocked your phone, then it won't hurt inserting another sim in it. Theoretically speaking it should work and if it won't, then flashing is another way of making it work.

Who are these ignorant people telling you this and why are you listening to them?
1) Verizon also uses CDMA, so having CDMA is the reason it WOULD work with Verizon.
2) All the carriers in the U.S. get the same phone. All the bands needed for a specific carrier are activated when the SIM card is installed. The only reason it wouldn't work is if Sprint had not unlocked the phone after you paid it off. It would be locked to Sprint to prevent you from not honoring the purchase agreement. And even then it would be blacklisted on Sprint network, if you didn't honor the purchase agreement.
3) if inserting the SIM card for another carrier doesn't automatically change the firmware, then do what this guy said:

Sprint, at&t and even verizon said my phone wasn't compatible even after I told them sprint unlocked it. I had no idea about all this cdma, gsm crap when buying the phone. I have never had a decent phone like an S8. All my phones have been cheap prepaid phones since now due to the fact no one would ever finance me for one. I was SOO freakin surprised and happy when someone actually agreed to finance me, I figured I could pay off the phone and then switch. After paying off the phone is when these companies said it was incompatible. Weird thing is I went to IMEI.info and it says it IS compatible and IS unlocked for sure. I then went to at&t online and after typing in my imei number it also said it was compatible. I'm so confused. I am going to take it up to at&t tomorrow and see what happens when I buy and insert a sim card. If it turns out to be sim locked is there a way to bypass this? I truly have paid the phone off and after doing so I asked sprint (on the phone) to sim unlock it, they said they did.
Please do not listen to the idiots at the mobile companies. There is ZERO difference in the S8, ZERO!!!!! If It's not sim locked it will work on ALL carriers, both cdma and gsm.
If It's still sim locked, some people have had success paying a third party to provide a code. But I would try sprint first since They said it should be unlocked.
My guess is that it will work fine with another sim card.
I would either flash the att firmware or the unlocked firmware on it.

Should I flash the att firmware before inserting the sim or only if the sim does not work? Also is there a way and should I back up my sprint firmware or should I be ok? Thanks.

3) if inserting the SIM card for another carrier doesn't automatically change the firmware, then do what this guy said:

It says this guide is only for snapdragon S8's I have an exynos S8. Is there another guide for that one? Nevermind, IMEI.info said I has an exynos, I guess it was wrong info. CPU-Z says it's a snapdragon 835. I'm assuming the CPU-Z info is the correct info?

You said you purchased that phone from Sprint directly. It's a snapdragon. Exynos is in the international version, which Sprint does not sell.

I purchased it from Best Buy Mobile, had to sign with sprint because no other carrier would finance me.

If you bought it from Sprint (or even just used it on Sprint), then you have a Snapdragon 835 S8. Only the Snapdragon variants have CDMA bands for Sprint and Verizon. Only the Snapdragon S8/S8+ variants are sold by carriers in North America -- so they can be cross compatible with Sprint/Verizon/AT&T/T-mobile/Canadian carriers. That's why whoever told you this nonsense is so ignorant.
If you had IMPORTED an Exynos variant from like England, then you would be limited to AT&T or T-mobile. But you have the "universal" Snapdragon model. Now the Exynos variant has an easily unlocked bootloader, which is a reason people import them, but that's another topic altogether.
As long as your Snapdragon 835 S8 is SIM unlocked (you have paid for it in full, and Sprint says they have unlocked it), you can take it to any other carrier or even an MVNO (like Straight Talk) and use it.

If you used it on Sprint, you have Snapdragon 835. Only the Snapdragon S8/S8+ variants have CDMA bands for Sprint and Verizon, in addition to LTE bands.

Should I flash the att firmware before inserting the sim or only if the sim does not work? Also is there a way and should I back up my sprint firmware or should I be ok? Thanks.

Please do not listen to the idiots at the mobile companies. There is ZERO difference in the S8, ZERO!!!!! If It's not sim locked it will work on ALL carriers, both cdma and gsm.
If It's still sim locked, some people have had success paying a third party to provide a code. But I would try sprint first since They said it should be unlocked.
My guess is that it will work fine with another sim card.
I would either flash the att firmware or the unlocked firmware on it.

Since you phone is paid off, when you go to AT&T, try AT&T Prepaid (formerly called GoPhone). It's really for people who already own their phones.
Same high speed data off the same low-lag data servers used by "contract"/postpaid AT&T customers (with one exception, which I'll warn you about),
same in-store AT&T customer service as contract/postpaid AT&T customers,
same AT&T SIM card as contract/pospaid service. (The store may have SIM cards labelled "AT&T Prepaid", but underneath it's the same AT&T SIM card. If they try to charge you for one, tell them you want the FREE AT&T SIM card. It's the exact same thing.)
Make sure you go to an AT&T corporate store, not a "franchise" store. At the AT&T corporate store they will even give you free AT&T SIM card to use for AT&T Prepaid. (Franchise stores will try to sell you SIM cards.)
The advantage is AT&T Prepaid is much less expensive service than "postpaid" AT&T (contract service). Since you already own your phone in full, all you need to pay for is monthly service. You don't need to pay extra each month so you can get a "free" upgrade to a new phone in 2 or 3 years. (Not free, you are really paying for it with extra fees each month.)
You would want the $45/6GB plan on AT&T Prepaid. Do not fall for the $60 "unlimited" plan. The $45/6GB plan gives you plenty of UNCAPPED high speed data/unlimited calls/unlimited texts. Whereas the $60 plan caps your data speeds at 3mbps to compensate for it being "unlimited". AT&T Prepaid uses same data servers as their AT&T postpaid customers and I get ping speeds often less than 30ms, most often 26-29ms, which is fantastic low lag speed. (Lower pings are better, lower ping speed = less lag). If you go to even a service like Cricket (owned by AT&T, but you won't see any AT&T logos anywhere), they use proxy server farms and you often get triple digit ping speeds (high lag). This is also why Cricket has to use a DIFFERENT SIM card from regular AT&T. Higher ping speeds make it seems like your download speeds are much slower than they are.. due to LAG. Plus Cricket caps ALL download speeds at 8mbps. Until AT&T Prepaid (formerly called GoPhone) introduced their $60 "unlimited" plan, ALL their plans were uncapped high speed data. They didn't cap download speed at all. But now they have started capping speeds with the $60 "unlimited" plan. So STAY AWAY FROM THAT.
With the $45/6GB plan, if you autopay each month, you can save $5 and only pay $40 per month. So, $40 per month for 6GB data, with UNCAPPED low lag data straight from AT&T. Don't let them charge you for a SIM card! AT&T Prepaid uses the exact same SIM card as "regular' AT&T.
If you decide you don't like it, for whatever reason, you can switch to "regular" postpaid AT&T. But since I always pay for our phones in full, I like to save on monthly service. Although there are tons of MNVOs with prepaid service, they all use proxy servers with high lag (high ping speeds). Even AT&T's own Cricket is configured as an MVNO, to compete with MNVOs like Straight Talk. But AT&T Prepaid is not. It's "pure" AT&T, but at budget prices -- which AT&T uses to compete with actual carriers like T-mobile and Sprint.
You can "bring your own phone" , which in this case is your fully paid for Galaxy S8.
How do I know which ones are the corporate stores and which are the franchise stores? I'm looking at the St. Louis map now. Some say at&t authorized retailer and then some just say at&t.
I have a sprint model and I unlocked it.
It works with T-Mobile and gets LTE
It works with att and gets LTE
It works with Verizon my current carrier now and also gets LTE
Highly recommend flashing the unlocked software if you go this route the sprint software with non sprint SIM cards is very annoying.

It worked! Thank GOD! In my room now I get -90/-100 with att and had -100/-125 with sprint. It is using HSPA and I can't find LTE on here to switch over. It stays on 3g, it never goes to 4g or LTE, how can I fix that?
So please tell me what I need to do to delete the sprint crap on here and put att on it. Thanks guys.
Not being rude, but you've been told many times on here What to do , reread the posts.
Follow the directions, we can't spoon feed every little thing.

Ok, so I want to do the prerequisites - check.
Then just do the carrier switching part and I'm done right?
Do I do all this with the sim card installed or not installed?
Sorry, this is my first time doing this.
Ok, I did what the guide said. During the flashing standard firmware part after clicking start is said FAIL! SHA256 is invalid. I ended up going back into ADB, rebooting and trying a different att firmware download and now the phone works. Weird thing is, I don't see alot of the apps that I had on an old phone with go phone and 4g LTE is not working, it's not even an option. What should I do if I want to wipe clean the phone to stock samsung android, not stock sprint as I bought it. Then I could insert the new go phone sim and it will install those apps and turn on 4g LTE? I'm learning guys, slowly but surely. I love this kinda stuff, so please bear with me here.

Authorized retailers are code for "franchise stores". They are not owned by AT&T nor run by AT&T. They do not have actual AT&T employees and they will nickel and dime you for every little item, like SIM cards. Whereas "corporate" AT&T stores will give you free AT&T SIM cards.
When AT&T Prepaid was called GoPhone, event the AT&T stores sold a GoPhone SIM card "kit" that had various sizes SIM cards with plastic shims for $15 -- which was totally unnecessary. I just told them, "NO, I want a FREE AT&T SIM card which fits my phone." And at the corporate stores they have to give it to you. AT&T and AT&T Prepaid (formerly branded as GoPhone) uses the EXACT same SIM cards. It's just they had some "labelled" as GoPhone but underneath it was the exact same thing.
3or 4 years ago, I had a friend buy a brand new Samsung Galaxy phone "on contract" INSIDE an AT&T corporate store, then immediately paid it off with his credit card, and switched to GoPhone -- all in the same visit -- and they did NOT even touch his AT&T SIM card inside his phone. It's just an internal AT&T accounting change. Now GoPhone has been re-branded as AT&T Prepaid to make it less confusing.
