I have 10i, but would love to switch to a provider that uses 10a frequencies. If I cross flash will the radio switch the frequencies?
It might sound like a stupid questions but my other phone is a Motorola Dext (aka Cliq) The 3G radio chipset in the Dext is multi-band, original radio firmware allowed the use of all the bands i.e 850/900/1700/1900/2100. Software updates later killed that option and allowed the phones to use 3 of the possible bands; decided by the telecom pushing the update. (Yes, I did update before finding this out -arse) BTW, if you feel bad about 1.6, Cliq/Dext sold in 2010 is stuck on 1.5, although at least there are (more or less buggy) custom 2.1 roms out now.
Apparently it's a common practice to use multiband radio and use firmware to lock it down, it is cheaper than manufacturing two distinct chips. But, common, does not mean universal.
Soooooo... Anyone knows if the radios are identical and we can cross flash to change our 3G frequencies; or are 10a and 10i using different, hardware locked, chips?
Try to use R2BA026 LAM firmware.
Is for X10a.
After that, you have to recreate the APNs.
It might work... but depends what frequency is supported by your carrier.
If is one from your X10i, it will work for sure. If not ... probably EDGE is your only choice because afaik X10 has only 3 bands for 3G
I want to go from Vodafone 900/2100 to TelecomXT 850/1900. XT has NO GSM network, it's all 3G and has superior data rates and speed. In NZ, because of large distances between towers outside the CBDs of the main centres, the first (lower) frequency is more important. Voda falls back on its gsm network and their 900MHz 3g coverage is not as good as telecom's 850 coverage. What I'm trying to establish is if the 3 frequencies are rom or hardware tied.
TelecomXT has a better network and far better prepay deals on data and sms, I used it with my 3g iphone and would love to go back to the fold.
I really don't want to brick this phone. So I've been trying to read up on how easy it is to flip back and forth with 10a/i roms. Or, flash 10i rom with a baseband? I'll try to flash in the weekend unless I get warned off,
i believe it will not work that way...x10i and x10a use two different 3g radio antenna chipset. so it will stay the same even though u have flashed to x10a firmware...

I agree. its not a software issue... its hardware... and unless you're apple, you can't get away with a software 'fix' to a hardware issue
An item you are forgetting about is each band has a power amplifier tuned specifically for that band. So even if the chipset supports 5 bands, it will only work on the bands for which it has power amplifiers for.

I created this thread because there seems to be some confusion as to the differences between the T-Mobile, Euro, and (soon to arrive) AT&T branded versions of the Galaxy Tab. I'm sure at some point enough information will exist for a proper XDA wiki entry, but for now, we need a thread for each variant with specs, and where possible, hack/flash options, including phone and data connections.
So this will be the US AT&T thread, where we can get the facts straight for those who wish to use AT&T as their carrier with a Galaxy Tab.
THIS THREAD IS FOR US AT&T GSM ONLY, DISCUSSIONS ABOUT CDMA (SPRINT, VERIZON, ETC) SHOULD BE IN ANOTHER THREAD!
Other carrier-specific threads:
US Tmobile Galaxy Tab flashed to make phone calls (currently phone works only, no 3G data)
(I would suggest to moderators that other non-AT&T and CDMA-related posts be removed or moved to a more appropriate thread.)
Alright, for starters, let me post the US AT&T frequency information, so that n00bs can be up to speed.
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
850 MHz UMTS/WCDMA/HSPA 3G
1900 MHz UMTS/WCDMA/HSPA 3G
This should be helpful when we discuss the Galaxy Tab specs. I will be re-editing this post as new information comes in.
[future verified information can be placed here]

[reserved for links as needed]
Actually, the SGH-I987 version that AT&T is getting has already launched. In Canada. On two carriers.
The Bell version has two model numbers on the back, the GT-P1000M (firmware is different, and presumably less crippled than what AT&T will release, hello sideloading), and the FCC model number of SGH-I987 on the back cover, so the internals are identical to the AT&T unit.
And you missed a few bands, any Galaxy Tab with a SIM card will work on 2100 UMTS as well as 900 and 2100 GSM/GPRS/EDGE.
AT&T should be releasing their branded version of the Galaxy Tab on the 21st (just a few days from this posting). If I understand right (this is where the value of this thread will come into play), the specs for the T-Mobile version are different in terms of the 3G radio frequencies.
IF this is true, then it would mean that if you plan to use AT&T as your US carrier:
You must run an AT&T branded Galaxy Tab
You must run a Euro-spec Galaxy Tab*
*specific procedure for this to work is unverified at this time
Price
At this time, the price for an AT&T branded Galaxy Tab will be $650 from AT&T. It will have two pay as you go plans--$14.99 for 30 days and up to 250MB of storage or $25 for 30 days of up to 2GB. This is similar to how they currently handle the iPad plans.
HOWEVER, as many people here on XDA-devs know, it has always been possible to take a GSM SIM and move from phone to phone, and provided that the frequencies are compatible, the services should carry over and the device change remains largely in the control of the owner. Of course, they can detect the IMEI at the carrier, but in most cases they are not blocking IMEI's. If your device has the right radios and frequencies, it should work. In the past, this has been the case with most devices.
So the question is: Does the Euro-spec Galaxy Tab have the same frequencies as the AT&T branded Galaxy Tab? It should, considering that the specs for the Euro version seem to reflect the same frequencies that AT&T uses.
In theory, getting the software right on the Euro-spec Galaxy Tab should be a matter of flashing a working cooked ROM to enable phone and 3G connectivity.
As of the time of this post, one or two people have managed to get a Galaxy Tab phone service working with AT&T, although I am unsure about 3G.
Again, the purpose of this thread is to clear up these questions, and keep it focused on getting a fully-functional Galaxy Tab on the AT&T carrier. Meaning both phone and 3G working as normal with any other device.
I can confirm that the European Tab works fine on at&t with full 3G and Voice dialing.
It is model GT-P1000
FCC ID: A3LGTP1000
I have been using it for the past few weeks and it seems to support all the required frequencies. It has operated in every mode including (G)PRS, (E)DGE, (3G) and (H)SPA
Stupid question then. Doesn't Canadian Rogers use the same frequencies as AT&T?
They sell Galaxy Tab too right? Does their Galaxy Tab have voice call capability?
I am interested in buying Galaxy Tab that could do 3G on AT&T and can make voice calls so I could use it as my phone ;-)

Interesting news... I bought an unlocked device in Kuwait City and it matches that FCC id number, but it had some Arabic apps loaded onto it, does this mean the euro and middle east versions are the same?
Also, how much of AT&T's network is is 850?? I didnt think the 3G would work back in the states... btw, my home is in the DC area is that helps.. Thanks!

The FCC docs actually say that the GT-P1000L, N, T models do support 850GSM and 850WCDMA(3G):
Type the device's FCC ID info in, (A3L is the manufacturer code for Samsung). Look at the documents in the 824.20 (GSM "850") and 826.40 (WCDMA "850") lower frequency ranges.
The actual test report docs list GT-P1000L and GT-P1000N and a clarification doc from Samsung says the GT-P1000T model is just a renamed L one.
This is great, it's exactly why I wanted to start this thread. SO, one person at least has a Euro-spec (GT-P1000) machine wortking with voice and 3G data on a US AT&T network.
Someone needs to post specs on the GT-P1000. Because right now, it would seem that the P1000 is the best bet for those who want to use FULL functionality on a US AT&T network.
My personal motivation for this thread is to get solid information on what model Galaxy Tab will have full US AT&T functionality (voice and good 3G data connect), and HOW to achieve that (choosing the right Galaxy Tab and flashing the right ROM). Once this is nailed down, I'll buy one. I just need to know which to buy and what to do to it.

Not FULLY working on at&t's 3g network. The 850 band for 3g is still missing and 850 is their primary 3g band and it's slowly replacing the 1900 3g band. The reason they changed was because the 850 3g band can cut thru walls better and give you a better 3g signal. I remember when my area had only 1900. My 3g sucked. Very spotty unless I was outside. I instantly noticed when the 850 upgrade took place. Solid 3g even in the darkest areas of my basement @ work. There will be an unlocked 850/1900 3g band version on the tab but it looks like it was pushed off until early 2011. Probably because they knew they would never sell any of the current north american models with the 850/1900 3g bands (bell, rogers & at&t) For what it's worth, you can pre-order that version here:

Who said at&t's primary 3G is 850Mhz?
That is just false information.
Their primary is actually 1900Mhz and they are beefing it up with new 850Mhz towers, not instead of current 1900Mhz existing in infrastructure.
Places who only recently got 3G service might be on 850Mhz but all those who got 3G up until 2 years ago are all 1900Mhz with the addition of 850Mhz.

Yea this article and all the others stating the same are copying the same wrong source.
At&t never said they will be replacing 1900mhz with 850mhz...they said they will be ADDING towers and expending their network on 850mhz.
Here in the sf bay area the netwrok is mainly 1900mhz but they are ADDING new 850mhz towers so now we get mixed frequencies in places where signal was bad. They are certainly not removing 1900mhz towers.

This thread encapsulates my concerns exactly. I want to use my tab as a phone, and am on ATT, so will wait to see how to best implement this agenda before purchasing anything. I have a couple of concerns:
1) I think that the Galaxy Tab forum should be split amongst various carriers, since future roms and such will likely be device specific.
2) Now that more information is coming out with regards to the Nexus s and Galaxy 2, I am wondering whether I should hold out. I do want a large screen, but the development community/google support for the next Nexus phone is hard to pass up... maybe I will buy both!
Regarding splitting up the forums, I don't think that's a good idea. We tried it for the Galaxy S models and it is something of a clusterfuck, and not as much knowledge is being shared IMHO.

So I am not an expert on cell phone technology but I have been doing a lot of reading about the Nexus 4 (my new phone) and T-Mobile (my carrier) and I noticed that the AnandTech review which says that
Band 4 (AWS) could essentially be supported with the power amplifiers and transceiver that already are onboard the Nexus 4
Click to expand...
Click to collapse
This has me wondering... Part of me imagines that given the uproar over reviewers over lack of LTE, if what I wonder is true then it would have been brought up.
Regardless, T-Mobile is building it's 4G LTE network on the AWS spectrum (. Does the review at AndandTech imply that the radio could be updated to support AWS LTE? That is, could it be possible that the phone will receive a radio update to support the T-Mobile LTE network when it rolls out in 2013? It certainly would make T-Mobile being the only carrier to offer a subsidy of it a bit clearer.
So no one has any idea I guess??
I posted this awhile ago if you check the fcc filing for this phone it shows they tested Band 4
check the sar test report #1
Wow its been a long time since I've been here! I see all of you are still busy!
... so basically, I'm going to buy an S4, but I'm not sure WHICH I should buy ... and I'm not sure where I should put this question since all the models are spread all over the place, but since I'm in Canada I thought this place would be a good start :laugh:
So basically, from what I've seen, the AT&T (i337) model is quite limited in out-the-box bands, and also has a locked bootloader. From what I've come up with, digging through information about all the models and Canadian carriers, is that the two best models for use in Canada seem to be the I337M and the T-Mobile M919 ... I really wanted a Samsung branded phone, but it seems if I get the I9505 I'll be missing out on a whole bunch of radio bands ... from what I've seen however, the unlocked I337M has no branding on it though ...
So basically what I've come up with is that both the T-Mobile M919 and the Canadian I337M both have unlocked bootloaders ... and they all run on the same GSM freq.
Someone please correct me if I'm wrong here, but, it looks to me like both the M919 and the I337M also share the same LTE bands, which are LTE 700MHz (Band 17) / 850MHz (Band 5) / 1900MHz (Band 2) / 2100MHz (Band 1) / AWS (Band 4) / 2600MHz (Band 7)
(my sources are http://www.samsung.com/us/mobile/cell-phones/SGH-M919ZKATMB-specs and http://www.pdaplaza.ca/products/Samsung-Galaxy-S4-SGH%2dI337M-16GB--Black-Mist,-Unlocked.html - I can't seem to find a reliable source for the LTE bands the I337M has ... on samsungs website it has a * Dependent on market and nobody seems to list straight up specs for the I337M ... actually it lists a completely different set of LTE bands which I'm pretty sure is wrong ... they list 1800 instead of 1700 and 800 instead of 700 which I know is incorrect for Rogers at least)
It looks to me, like the only real difference between the I337M and the M919 is that the M919 has a AWS (1700) 3G radio band, and the I337M has a 900mhz 3G radio band instead of the AWS band ... however, I ALSO have read that the AWS band on the I337M can be enabled (again, correct me if I'm wrong!)
If everything that I have read through is correct, it would seem to me like the I337M would be the 'ultimate' North American model, supporting more frequency bands than any other version (besides maybe the i9505 which lacks some bands I would probably need) ... unless its actually possible to somehow unlock all these bands on every version, and I just didn't get that deep into reading about hacking these phones yet ...
If I got something wrong here please let me know ... I would like to buy one soon and start flashing it
Thanks!
Lets put it an easy way, if I had the choice again, I would have not got the att galaxy s4 us version, I would have got the Canadian S4 i337m. My opinion only.
Or the Google Edition but its going to run you like 700-800$

If you're in Canada why not buy the i337m?
My i337M is completely unbranded once I installed a custom ROM and I managed to enable the AWS. Unlocking it has been a different story though :/
Well ... I just want the phone that has the most bands (its not really a cheap phone!), I'd like to get as much as I can for my money. I honestly have no idea if all the North American models have the same radio hardware or not, but at least on Samsungs website, they list the I337 (AT&T) with many less bands than the T-Mobile M919.
Funny enough, on Rogers website it lists the I337M only having 2100/2600 as the LTE bands, but on Bell/Telus it lits the I337M as having 700MHz/ 850MHz/1900MHz/2100MHz/AWS/2600MHz
It seems silly to me to actually manufacture different radio hardware for all the different North American models ... considering they almost all use the same bands except some exclude some, and there is one different one (3G AWS on M919 vs 900Mhz 3G on I337M)
I wouldn't get the AT&T US version ... as far as I know nobody has been able to unlock the bootloader. But apparently the M919 isn't locked.
I considered the Google Edition, but as someone said, it will run 700-800 (and you can't 'officially' get it in Canada)
Anyways, I found an unlocked I337M and I believe it is also unbranded ... so I bought it. If its not, I'll just flash it
I still am curious as to what they actually do with the radios though ... if they actually use different hardware or just lock the bands in the firmware (I'll take a guess the international I9505 actually has different hardware, though)
I think it would cost Samsung more to design different radio hardware for all the different North American providers (considering they almost all run the same/lots of overlapping bands) than just putting firmware locks?

I337m has all the radio bands, handles the lowest CPU voltages while still being stable... has an unlocked bootloader, and simply kicks butt.
Simple modem firmware flash fixes any location specific, and in my case, non-existant radio band issue.

I'm in the UK and about to buy a LG V20 VS995 from Hong Kong off of Ebay. Pretty sure I've checked the available frequencies here especially the 800 & 900MHz bands as these are the ones which travel the furthest and are able to penetrate buildings better than the higher frequencies. I've attached a table of the main UK networks and what bands they use. So can anyone let me know I've got this right before I purchase. Many thanks
Hi
I am in the UK also and currently using O2 with no problems. I have also used an EE SIM again with no problems. The only thing you need to be aware that the VS995 will not pick up the SIM APNs automatically, at least that is what I found, so you will need to find the APN for whichever network you use. There are off-line APN finders you can find via Google. Hope this is of some help.

Hi, the LG V20 VS995 doesn't support ALL the bands used in the UK. It doesn't support one of the LTE bands used by Vodafone - the 2100Mhz band. So if you're on the Vodafone network, you may find that 4G/LTE speeds might be slightly slower.
I got all of this information from frequencycheck.com and it's usually where I get all my information on the bands that smartphones support.
The best option if you want to get a V20 that supports ALL bands in the UK (at this current time), is the LG V20 H990DS (Taiwanese Version).
That is the variant that I own and it supports every single band used in the UK.
The only other variant that supports all bands is the LG V20 H990N (Hong Kong version), but it only has Cat6 capability as opposed to the H990DS's Cat12 capability. Therefore, the maximum speed you'll be able to get is 300Mbp/s on the H990N - whereas on the H990DS you can get up to 600Mbp/s.

I'm not really sure that's true according to gsmarena it does support band 4(1700/2100) admittedly that's not the same as 1(2100). I'm sorry but in my ignorance I don't know . Maybe someone who is more enlightened could tell us what the difference is. See here.
Also the bit about the Cat 6, 9, 12 with LTE does not really bother me. For the VS995 it's LTE-A (3CA) Cat12 600/150 Mbps but for the H990N it's LTE-A (2CA) Cat6 300/50 Mbps. Now I ask you is anyone on this planet going to realistically even touch or even dream of a download speed of 300Mbps on a mobile network. I'm not even remotely getting this on my home fibre and we're watching UHD movies!!

LTE Band 1: This is one of the paired bands that was defined for the 3G UTRA and 3GPP rel 99.
LTE Band 4: This LTE band was introduced as a new band for the Americas at the World (Administrative) Radio Conference, WRC-2000. This international conference is where international spectrum allocations are agreed. The downlink of band 4 overlaps with the downlink for Band 1. This facilitates roaming.
I guess I'll soon find out, not sure how though

To be on the safe side, I would just go for the H990N or H990DS. You also don't get the horrible, disgusting Verizon watermarks and logos (software and hardware) if you go with either of the H990 variants. But if you're not going to be using Vodafone, it doesn't really matter - because Vodafone is currently the only UK network that uses B1(2100) for 4G/LTE. Have you already ordered the phone?
i have a h990n in the uk all networks with full 4g
Don't buy CDMA phones for use on GSM carriers, or phones not specific to your region! Though nearly all CDMA phones from Sprint and Verizon in the USA support GSM protocols like 2G: GSM, 3G: UMTS/HSDPA/HSPA+, and some LTE bands, they are not always accessible. VS995 doesn't support Vodafone UK's LTE B1. I ran into problems with invalid sims and poor coverage because not all bands were unlocked by Verizon. If you want a V20 save the hassle and buy a GSM unlocked V20: US996, H990, H910 (won't get OTA, so flash H915 KDZ), H915, H918.

Had a look at the above link and have got the following compatibility
GSM: 2G, 2.5G 100% (2/2)
UMTS: 3G, 3.5G, 3.5G (4G speed) 100% (2/2)
LTE: 4G 75% (3/4)
So I'm chuffed especially after reading this concerning the band/frequency I'm missing...
2.6GHz frequency band
The 2.6GHz band is the other frequency which was auctioned by Ofcom and it’s essentially the opposite of the 800MHz band. So it’s not great at travelling over long distances, meaning that masts need to be closer together to deliver reliable coverage and as such it’s not so suited to rural areas.
It’s also not all that adept at penetrating walls so indoor signal on the 2.6GHz band won’t always be perfect.
But on the other hand with 35MHz blocks available it has a high capacity. So it can cope with thousands of simultaneous connections, which in that sense makes it a good fit for cities and other busy areas.

I ordered the phone and hope to get it in the next couple of weeks and I will post back my experiences. I ended up getting it at a good price too

Hi
I am in the UK also and currently using O2 with no problems. I have also used an EE SIM again with no problems. The only thing you need to be aware that the VS995 will not pick up the SIM APNs automatically, at least that is what I found, so you will need to find the APN for whichever network you use. There are off-line APN finders you can find via Google. Hope this is of some help.

Out of curiousity were you able to update from Nougat to Oreo? I had a quick preliminary look and didn't see any straightforward method via official channels.

No, very few American V20 users have been able to update to Oreo as the providers have not released Oreo for the phone. To keep ahead with security updates I use a custom Rom on my V20 (Alpha Rom ) but you need to have the Bootloader unlocked and the phone rooted to use it. Hope this offers some clarity.

Will probably stick with the stock ROM for a while until I'm settled in with the phone. Has choosing the Alpha rom negatively affected the performance of the camera or sound quality at all?
Some of the reasons for getting this phone is the renowned DAC and the camera esp in manual mode (apparently auto could be disappointing).

No negative affects. Alpha Rom is actually based on the last stock Rom from Verizon with some modifications.

Okay thanks for all your help. I'm expecting to get my phone sometime before Christmas
Just looked at the delivery estimate and it was anywhere between Sept 4th and October??th and it was ordered about 10 days ago. I guess it's to be expected coming from Hong Kong.
:good:

Well picked up my new V20 VS995 today and before I launch myself head long into customising it I've posted some questions in the main thread here I would really appreciate any help you might be able to give. I was going to post it here but I thought that would be unfair to load you with a barrage of questions.
The whole process seems so much more complicated than with my Note 4 and I there is a lot less handholding esp with the AΩ ROM'S initial post. For a relative novice it seems an absolute minefield.
