Samsung Galaxy a20 on at&t - Android Q&A, Help & Troubleshooting

I believe there's 2 versions of this phone. Or at least that's what Amazon has made me believe. One has all the at&t lte bands, (1, 2, 3,4,7,12 etc) and one doesn't.
I'm using att prepaid which hasn't been all that bad if that makes a difference in what att enforces.
Background aside, has anyone used either of the versions on att or can confirm there's actually 2 versions of this phone (aside from the metro by tmob that seems too new to be on the market; configured for metro that is)?
Amazon is a confusing jungle when it comes to phones and actual service compatibility -_-.

yup false alarm...........
I don't think the retraction of the tweet is any indication T-Mob wont be getting the S2. With the Galaxy 4G coming out in a few days, if mainstream customers new there was a phone twice as good on the horizon it would obliterate S4G sales. Plus from my understanding there's nothing in the specs that eliminates T-Mob as a possibility. 90% chance T-Mob gets this phone, which I'm of course stoked about.
This phone is said to be shipping with AT&T's 3G, but that it will work with any carrier. So, for you T-Mobile users, it will probably work, but only for 2G speeds. Sorry.
There is absolutely no way Samsung will make this super phone and limit its data potential to Att's ****ty 3G.

dont forget tmobile has a 5gb limit its NOT unlimited
Per the link you supplied:
HSPA+ 21Mbps/ HSUPA 5.76Mbps
EDGE/ GPRS Class 12
Quad band GSM 850/900/1800/1900
Quad band UMTS 850/900/1900/2100
Seems to me T-mobile's HSPA+ will be compatible, unless I'm completely missing something.
And to the above comment, 5G is plenty, even for most heavy users.
Won't this device support both 3G company's? From the specs of the link

Sure, T-Mobile UK is compatible
T-Mobile US's HSPA+ uses 1700/2100 or AWS.

Gotcha. I don't see why T-mobile wouldn't get this phone, as i said before, suppressing of information seems to be just a marketing strategy to not crush S4G sales coming up.
they wont get this phone immediatley as it will complete with the sgs 4g which they are getting.. eventually they may get it.
If the device is coming out in march outside the states, I'd think the new one will come out in some form in June or July like the last one did. That will give tmo a few months to sell their vibrant 4g and then allow it to be a decent midrange model thereafter. Considering that the 4g is going to be 149 with contract, its already the price of of a non flagship T-Mobile device. That could mean we have a small chance of getting this phone in April or may. They still need to make an aws version in order for us to have the phone on tmo. Given how much market share they made with the last galaxy I really think Samsung will want to not lose their lead in android market share. We will get at least some version of this phone. I hope now that US carriers all have ffc and the other features left out of the previous galaxy s for the states, that they won't need to give us a stripped gs2. Just my 2 cents.

i'm waiting for the AWS version of the SGS2.... it's gonna be a long loooooooong wait, with the SGS4G stuck in between
I'm almost certain it is.
At least I'm hoping

that's one thing you do not need to worry about
look at the line of Galaxy S (Generation 1) phones, they have practically 1 variant for each single cell phone carrier on the planet.
some carriers even have 3 models of the same Galaxy S family
for example Tmobile USA have:
Galaxy S Vibrant
Nexus S
Galaxy S 4G
so we'll see our own flavor of SGS2 in due time
knowing their crazy naming scheme
i'll not be surprised to hear Galaxy S Vibrant II LOL
and probably comes with something chopped off like missing FFC or who knows what.
Hopefully they'll get some version of it... ATT blows..
So... any idea on how we're going to know which is the original phone model?
I guess we would just go off of the one coming out in March, and then try to buy that model off of whichever carrier carries it?
Because I wasn't very fond of the different versions of the Galaxy S - the Vibrant, the I9000 (which might be the same), the Captivate, the... who knows what else? Each carrier here (Rogers, Telus and Bell) had different versions. I don't even know what other ones like Virgin or WIND may have had for it (if they carried it).

[Q] Have a tmob s4 version thinking of moving to Verizon

Long story short my work has offered me cell phone service but they only have Verizon or ATT.
I have a tmob s4 ... rooted and custom rom. Are the phones "essentially" the same so with a kernel and modem would I be good on Verizon?
Any caveats to be concerned with? its been probably 8 years since I had a Verizon plan but it does offer better coverage than ATT in the places I need...
thansks!

Only the Verizon S4 will work with Verizon, you'll need to go to ATT.

I see others that have used the Verizon s4 on Tmob so not sure why the reverse wouldn't be true... ill research more but I am finding that all the s4 hardware is the same... only software differences.. (possible that its not possible to get the Verizon software on the phone the hardware should be the same)...
maybe get some more input

I don't know where you're researching, but the S4 definitely has hardware differences.
Verizon is what's called a "CDMA" carrier. Their S4 includes hardware that can connect to both their CDMA and others' GSM networks.
T-Mobile has a GSM network. Their S4 includes only the GSM hardware, there is no possibility of using it with a CDMA carrier.
Most variations of the S4 also have slightly different sets of "bands" that they can connect to, so the speed you get will vary depending on both the network type and your S4's type. However, the S4 should be able to get at least 2G on any GSM network. Verizon's S4 has the widest possible area of use, because it includes both CDMA and GSM. It can be used on T-Mobile or ATT, but their S4s cannot be used on Verizon entirely because of the hardware differences.

I understand the networks are different.. what I am seeing is that the hardware is the same ... they all have the same chips.. the different carriers are just using software to use what they need
for example here:
http://forum.xda-developers.com/showpost.php?p=25953096&postcount=13
and this thread has examples of people who have used their Verizon on Tmob (voice, wifi, and 4g)
http://forum.xda-developers.com/showthread.php?t=2331131
long story short they say all the phones are the same... they just use different Radio software (plus kernel I assume)
The answer is simple: You will never use a T-Mobile S4 on Verizon.
Verizon S4 on T-Mobile is completely irrelevant, because they're designed to work that way.

There is NO CDMA radio in a T-Mobile GS4.
Even if it were, Verizon will not add foreign IMEID/ESN to their database. Without the IMEID/ESN added to the database you cannot get voice service. You could possibly take a provisioned SIM and get data only, but what good is that.
Sell the S4, buy an HTC M8 do S-Off, move on.
Your S4 will never work on Verizon.

[Q] Switching from VZW to TMo?

Hello,
First and foremost I'd like to say .... Man, it feels good to be back. I left Android for a few years due to battery issues. I just left VZW and switched from a iPhone 5 to a Note 3 on T-Mobile. My wife has a VZW HTC One (M7) and I was told it would work on TMo, so far we are having no luck getting anything besides Edge. Sorry if already posted but I did look around to try to find an answer. I have spent time talking to VZW, TMo and HTC and no luck. Will rooting give me the ability to fix this?

Verizon phones rarely work on other carriers. Besides the fact that they usually lock the SIM (meaning only VZW SIM cards will work unless you leave the US - ie: "global phone"), different cellular frequency bands are used. Specs on the M7 that I found on phonearena state that the VZW M7 uses 700MHz (band 13), which T-Mobile doesn't use (PA's specs aren't always 100%% though). So even if you could unlock the SIM somehow, you wouldn't get data; not at LTE speeds anyway. LTE radios in phones are actually fairly expensive components, so carriers will often order specific versions from the manufacturers that only support their own bands to keep costs down (and/or profits high).
I think your best bet would be to sell or trade the M7 for a T-Mobile or unlocked one.

[Q] Groupon S5 Deal: Work on T-Mobile?

Groupon has a deal for the S5 that says it's for "Verizon and GSM Unlocked":
https://www.groupon.com/deals/gg-samsung-galaxy-s5-smartphones
Is there any way to tell what model # this is? I'm guessing that it is a generic S5 and not the T-Mobile specific SM-G900T. If that's true, then it likely doesn't have the TMo specific LTE frequencies needed for full service (I'm in the Chicago area), correct?
I really hate having to find special versions of GSM devices to make full use of T-Mobile's network...
<TAP><TAP> Is this thing on???
Unlocked for all Verizon and GSM carriers.
On the same page --> https://www.groupon.com/pages/groupon-deal-images-gg-gsm-providers
Only thing is that it probably will not be compatible with WiFi calling features, but I could be wrong.
I know it would work but I was curious about whether it was the same model they sell via T-Mobile that has their unique frequency bands (1900/2100 I believe). Groupon responded to an inquiry and said it was a Verizon model so while I can't confirm it, I'm guessing it doesn't have the extra bands needed to fully make use of T-Mobile's LTE network so it would likely drop down to HPDPA+ in many locations.
According to the reviews, its a Verizon branded phone. A couple of the reviews are from T-mo users and they claimed to have issues with the sim/network not going to LTE, instead it uses their HSPA network.
If it was me, I would not buy this. It is cheap yea, but remember that the S5 is not compatible with the new band 12.
-edit-
The Chicago area isn't getting band 12 anyways, not anytime soon that is.
I'm using a Verizon S5 with a T-mobile rom and it works perfect 4g lte and all If you end up getting it just root it then look at my view forum posts.

(Q) Does the LTE versions of Samsung tablets have built in eSim like functionality?

My brother has an iPad pro and on the tablet in the settings he can browse many available plans from verizon, att, tmobile etc. He is able to purchase it and then immediately use the cellular data plan. I specifically like the $20 for 5GB for 5 months plan that he has access to. Do Samsung tablets have similar functionality (probably with esim)?

No. It uses a nano SIM. Find the best deal, get a nano SIM from the provider, and you're off to the races. There are no LTE versions being sold in the U.S. currently and the overseas versions don't work on CDMA so no Verizon and Sprint although they may work on their LTE networks for data because it supports their bands. The dialer and MMS definitely won't work. When the U.S. versions are released they'll be locked to the carrier you bought it from, loaded with their crap on it, the dialer will be disabled, and you can't reflash it using an international ROM because the model numbers are different.

So no phone/SMS/MMS function even if you have the right sim? I was going to look at the T-Mobile tab today but if those functions are disabled why would I want to pay $100 more for a tab with half the storage? I'll just get the WiFi version and run it if need be from my hot spot on my phone for internet access.
You can get genuine LTE versions from E-Bay no problem, why would you buy a 'carrier specific' one that then locks you to that carrier.
Note that, as mentioned earlier in the thread, that the S6 does NOT have an unlocked CDMA version so even with LTE certain carriers won't work.
In the UK using the LTE 256GB S6 with Giffgaff means unlmtd calls and SMS and 8GB data for $12 month, rolling 30 day contract (so no long term commitment). I'm always shocked that my US friends pay fortunes for phone and cable services compared to the UK.
When I travel in the States I use a UK Three sim in roaming mode that allows me to use my UK calls/SMS/Data allowance without any surcharge, still works out loads cheaper then using a US SIM.
