Sim Question - MDA II, XDA II, 2060 Accessories

I currently am using a Qtek 2020 as my main phone and I really like it except one thing. It uses 900/1900 USA frequencies and the company I'm using is cingular.
Well they offer a 850 USA frequency that seems to do much better indoors and just all around better signals. The reason I know is I have another phone that lets me use that freq and even indoors my signals are great.
So my question is can I buy a pay as you go sim or even get another type of sim from Cingular that will let me connect to the 850 USA frequency?
Or is that impossible due to the radio in my Qtek 2020? I did check the forums and I didn't find any info on this particular problem. I have heard of the new sim that will hold twice the info so I'm wondering if those will do what I'm wanting to do.
Thanks

Your phone is tri-band 900/1800/1900 so I think the sim for 850 wont work.

Thanks that's what I thought. Wishful thinking.....

90 days... But with the ETF, it's not like you're going to buy from T-Mobile then cancel and use it elsewhere after unlocking it through this guy. It's much easier to buy it off of a current T-Mobile subscriber if you plan on using it with another network.

you can just buy it from somewhere else. e.g. eBay and you might want to use it on other carriers. or you might just want to have an unlocked phone in case you travel and put different sim card on it.

Right, I understand the reason for having an unlocked phone... I don't think I'd pay that much for an unlock, but whatevs.
It seems like the XDA Dev team will probably have a way to unlock it in a couple weeks anyway especially if the OS is open.

You have to remember, it's only on T-Mobile in the US for now... I don't know if I should expect the developers of SIM unlocks (olipro/cmonex have done most of the work in that department) to get their hands on one... Maybe they'll grab one just for development, but for all we know their only plans could be to stay with the Touch Diamond/Pro/HD.
I dunno. We still don't really know how "open" the Android OS is yet. Although the kernel is open and freely available, it handles low-level hardware functions. SIM functions seem to be handled higher up in the Android stack and not all the Android source code has been released yet. Unless I'm missing something, it's a wait-and-see situation as far as SIM unlocking goes.
Even if I were to want an unlocked G1 (which I don't) I'd be wary of shelling out $50 for an unlocker to a phone that hasn't been released yet. And honestly, tmo's unlocking policy is very liberal as it is.
i am not a t-mobile customer, but the rest of my family is. i buy t-mobile phones all the time and i get the unlock code no problems. i'm not sure on if they are gonna give the unlock code right away, but if not i can always get the unlock code through my family. i hope we get a free unlocker before i get around to getting the phone
i work for t-mobile UK and on a contract you only have to have the phone for a month then you can buy an unlock code for £15
so you save yourself alot of money doing it via T-mobile UK plus they now issue most unlock codes on the spot unlike their old 28days in the post way
T-Mobile USA's policy is one, free unlock code every 90 days.
And I don't understand why you'd care about SIM-unlocking it, as the US version is really only good on T-Mobile's 3G network. T-Mobile uses different 3G frequencies than AT&T and the rest of the world. As I understood it, the European version will have a different radio set inside. I'd like to hope I'm wrong, but I understood that to be the case.

actually i think the G1 could be used anywhere

850/900/1700/1800/1900/2100 MHz
hex-band phone
i believe 900/1800 is eu band
and
850/1900 is at&t usa

You're confusing GSM frequencies with 3G frequencies. No phone maker yet has made a phone containing all the GSM frequencies, all the 3G frequencies, *and* the new tmo USA 3G frequencies. You can use the phone anywhere, but the 3G data would be crippled on anything but tmo-USA...and even tmo has said that the phone would pretty much suck without 3G.
ok you may be right about the frequencies
but the spec dose say that
HSDPA/WCDMA:
Europe: 2100 MHz
so it may not work with at&t 3g
but it might work in EU on 3g
Again, that's not what I'm hearing. The G1 in the US is configured for download on tmo's 1700MHz spectrum and upload only on 2100MHz. If I recall correctly, Europe does it all on 2100. That's the part I hope I'm wrong on, but just having "2100" on it doesn't mean it's configured for the particular part of the band that the Europhones use.

90 days of continued satisfactory service will do.
what you all forget is that he is doing it non profit.
all the time he has been doing these unlocks, its probably helped a lot to the upkeep of the site.

Euro/Asia 3G (WCDMA Band I) uses 1900 for UL and 2100 for DL while T-Mobile AWS (WCDMA Band IV) uses 1700 for UL and 2100 for DL. However, WCDMA Band I was called UMTS 2100 therefore the confusion.
BTW the T-Mobile G1 is a dual-band HSDPA phone (T-Mobile AWS and UMTS 2100)

[Q] t-mobile on fuze..

Has anyone tried this?? If I were to buy the phone w/o att will they unlock it no problem?
thx
they don't want to unlock it even if you pay full price, but they will give up if you insist long enough to one of their customer service representatives
what I did was to pay full price for the phone and get a new number and sim card with a prepaid plan, after spending my $25 from prepaid minutes I called and explained I no longer wanted their service and had paid full price, eventually they agreed to unlock it by giving me a code.. Insert a simcard from another operator and the screen asking for the code will show up.
3g on t-mobile is not working, but everything else does. At least for me. I'm using the Elite RC1 ROM
I think 3g may work if I replace the radio with one that supports 1700/2100 umts, but I don't know if that even exists
i think when the diamond first came out, it didnt support us 3g and they found a radio that allowed us 3g.
so i dont see why you shouldnt be able to get a radio that works with tmobile 3g

Nobody's been able to add a 3G band to a HTC device just by flashing the radio ROM AFAIK. When the Diamond came out, people were surprised that it didn't support the 850 MHz band like its predecessor, the Cruise, did. There was a later radio that allowed the Diamond to use the 850 MHz band, but only for GSM/EDGE. To do that, the radio in the device had to physically support the 850 MHz band. No subsequent radios, even the one from the US Diamond (which was identical to an already-released radio ROM) were able to make a Euro Diamond use US 3G. The only HTC-made device I know of that uses T-Mobile's AWS 3G band is the T-Mobile G1.

thanks for clarifying on this whole thread.
Fuze Working on ATT
So the radio that's in the FUZE won't work on Tmobile - i don't see the bands that the Gphone has. This really makes me wonder if I really want to switch over to ATT. technically I hate ATT.
It's like signing on to have big brother watch over you.
I have the same problem as you do. And I would switch to AT&T if it wasn't for the early termination fee in my t-mobile contract
i think thats what i am gonna do, unlock the fuze and use on t-mobile's EDGE.
i went to an AT&T store the other day and the guy explained the planes to me!!
to get something comparable to what i have with T-mobile i have to pay $130 a month for AT&T
i have the 3000 minutes regional plan $49 with total unlimited internet + access to t-mobile hotspot for $20
i pay 70 dollars
i'd have to get unlimited from at&t for $100 + $30 for internet
sprint's deal is actually isnt bad at all $99 for unlimited everything ( too bad they use CDMA, i go to the middle east once a year )
PS: work and i home i have access to a very high speed Wi-Fi
the radio will work, but you will only get EDGE speeds at best, not 3G. Tmobile's 3G band is AWS 1700 and the Fuze does not support that.
How bad is that? depends on what you do. I use my old Blackjack on Tmobile, and get about 125 kbps speeds. Enough for basic email, google maps and web browsing (when I am not carrying my Fuze)

[Q] Factory unlocks, ebay and international carriers.

Hello gents, I'll start with a short story to get you into the thread:
Me and my girlfriend live in Venezuela, our service providers are not up to par with american or european carriers in terms of available devices, so we bought an HTC Magic for each of us last year to try out Android, everything was fine, I learned how to root it, install roms and such, and we had a pretty good run with the phone and the OS.
Last week we got robbed and they took away our phones, I decided to get a Nexus S for her and I found one at a good price on eBay(270$+shipping) however this one is branded for Sprint, will I be able to go to my service provider and just tell them to attach my account to the phone I bought on ebay? or are the Sprint and Verizon Nexus S locked to those carriers exclusively?
If the answer to the second question is yes, then a third question is raised, can I in any way unlock this phone to use it on my non-american service provider?
I have seen other threads and the replies are always "the Nexus S is factory unlocked." but I dont know if this refers exclusively to the ones sold in the UK or retail stores in the US.
I apologize for any noobish behaviour, I'm a big fan of devices and gadgets yet I lack a lot of the technical skills you all seem to demonstrate.
Thanks in advance.

There is no such thing as a Verizon Nexus S. Sprint Nexus S have different radio bands than the regular Nexus S (I9020T/I9020A/I9023) and features a 4G radio with it. You have to make sure that the phone is compatible with your carrier's bands. Another thing to note is that the Sprint Nexus S is CDMA (No SIM card) as well.
All Nexus S models come unlocked regardless if you're on the contract or not. Sorry to hear about your incident
The model I bought is GT-I9020T, according to people on the internet(random links on google) this model works on GSM frequencies of 850, 900, 1800, & 1900. It supports UMTS 900, 1700, and 2100 frequencies.
My current provider works on 850 and 1900 for GSM and 850 for CDMA.
Do you think I will have trouble using the phone I bought for my girl?
I feel terribly dumb when I ask this, I cant explain why, hehe.
Oh, I think I figured it out, I bought for her the non branded GSM version, so yes, it will probably work on my provider.
But what happens if I buy a Sprint CDMA one for myself? Those are definitely cheaper, and CDMA seems to be better down here, at least more stable.
Thanks for your replies, and simpathy, it's been a rough week without a smartphone for both of us.

I'm not sure and I wouldn't say the CDMA version is more stable. I personally never used the Nexus S 4G but from what I can tell from threads is that there are problems with WiFi or something of that sort.
You might want to ask the carrier yourself via phone to see if it would be compatible or so. Just let them know about the bands the phone supports.
And that's interesting if your carrier supports CDMA and GSM.
CDMA = No SIM card
GSM = SIM card
GSM is more popular around the world. Just including that just incase!
Alright, so I talked to my carrier they said the following:
-If I buy a CDMA phone with no contract on the US I will be able to register it on their network.
-If I buy an unlocked GSM phone I can register it on their network.
I guess I'll have to buy a couple of GSMs just to be sure... even tho they are about 100$ more expensive.
Thanks for all the replies, catch you later!

Investigation: The mysterious 850 MHz band

I want to figure this out once and for all.
What services does this phone support on the 850 MHz band?
The big question is whether UMTS/HSPA works. NYC area has amazing 850 band coverage on AT&T.
If I were to put a prepaid AT&T SIM in my phone, set my phone to only operate on the 850 MHz band, and set the proper APNs (necessary for 3G?); would I be able to get data beyond EDGE?
Only one way to find out...
There's no mystery to it if you read through the [GUIDE] Set up Verizon Galaxy S3 as World GSM Phone (confirmed working) thread and the [BOUNTY] ($205 so far) Enable HSPA+ on 1900 MHz / 1700MHz for VZW Galaxy S3 i535 threads completely....
With the radio software verizon has on the phone, the galaxy s3 is quad band GSM (850/900/1800/1900) and single band WCDMA (2100).
We don't know if it has the hardware for WCDMA 850/900/1900 and until now, nobody has successfully flashed a different radio due to the bootloader lock. Keep an eye on the "enable WCDMA 1700/1900" thread for updates.
And just to answer another question that you might have, when my S3 was rooted and set up to work in Germany, I tried both T-Mobile and AT&T sim cards here in town. The problem with the S3 is that even if you try to select a different WCDMA band in the field test menu, the radio firmware will not allow you to change it from 2100. So in an area with T-Mobile PCS (1900) and AT&T PCS/CELLULAR (1900/850) WCDMA, each test I tried only ran on EDGE.

Wow... That really sucks.
So, there's literally no way to get 3G outside of Verizon aside from MetroPCS EVDO?

The first step is to experiment with different radio files, as one user in the 1700/1900 thread wants to do, but we need to get the secure-boot/bootloader unlocked so those files can be written.
Phones like the Rezound had the hardware for Quad-band WCDMA (3g), but took a radio file flash to make it work. The reason there is a bounty is because we -think- the Verizon S3 has the hardware, it will just take some work to get the software on the phone to talk to that hardware.
I know. I've been following the thread.
Was a little unsure of the details regarding frequencies.
As far as I understand, they're at a dead end. They need JTAG/UART to continue without worrying about bricks.

Yeah, and sadly, I lack the skills and the bounty probably isn't enough to attract a dev with JTAG and a phone to fiddle with to solve our issue
Verizon cdma is ran by nortel dual urban base stations the frequencies are 810-910 and 1840-2000mhz. The LTE is 690-760mhz 1x means that your on 850. 3g means your on 1900 or 850 depending on how far away from the site you are, and 4g means your on LTE. The LTE base station is ericsson but speeds will vary depending on whether or not the site is on fiber or T1 transport. Normally they keep the pre pay customers on the nortel dual urban... Oh by the way we are starting to decommission the lucent cdma on metro pcs sites and convert them to t-mobile GSM but luckily metro uses ericsson for LTE too so there's hope.

Bad ESN Verizon One hd in Canada?

LOL I'm an idiot, was thinking HTC ONE when I said one hd...
Found a really good deal ($170) on a bnib razr hd from verizon with a bad esn on ebay. Didnt really have the time to fully research it before the auction ended so I just took the chance and placed the order.
Did some searching after the fact and have found some really conflicting information. I know the phone would be pretty much useless in the states, but I'm unsure of its usability in Canada? I've herd they would work fine in asia and india so I'm basically curious if anyone knows the extent of how far verizon shares its blocked phone information? Does it extend to Canada?
I've herd on the states you need to have your phone activated onto a network? In Canada we just throw in our sim card and are good to go. Is this a different technology (CDMA vs GSM?). If so assuming the Activation portion of the phone is blocked could the sim card part of it still be open theoretically?
Assuming its possible to work with the bad esn does anyone know if I could use LTE on Bell/virgin?
According to bell it uses LTE AWS 1700mhz and LTE 700mhz and HSPA 850mhz and 1900mhz
According to gsm arena the xt926 uses:
HSDPA 850 / 900 / 1900 / 2100
4G Network LTE 700 MHz Class 13
Should be fully compatible no? I cant find any information on what class bell uses for their LTE, nor do I know if the class affects anything?

You can unlock it for gsm carriers in the us and its already unlocked for international use. I know with att u get h+ witch is good enough for me on straight talk. I average about 6mps.
Got the phone on the weekend. It works fine on bell/ virgin except I can't connect to lte. Does anyone know of it's possible to unlock lte? According to gsm area the phone should be compatible with lte 700mhz which is what bell uses... Will that radio com thing you guys use to unlock it for us carriers help?
