Help setting bands on unlocked J700P - Samsung Galaxy J7 Questions & Answers

I have a SM-J700P with a baseband of J700PVPU2BQJ2 that I unlocked and moved over to AT&T. I have it working on GSM but it says 3G at the top. I was told it may be on HSPA+, but looking here, I should be able to get on LTE just fine:
https://www.frequencycheck.com/carr...-sm-j700p-galaxy-j7-td-lte/at-t-united-states
I guess I want AWS?
Is there a way I can select the preferred band, and will that reset my phone? I have tried *#2263#, it doesn't work. Any help would be amazingly appreciated!
Also shouldn't my virgin boot screen switch to AT&T? I wish it would.
EDIT: Inputting "Q" on *#0011# doesn't do anything either

Do I also have the option of forcing bands?

Changing the CDMA Radio

I just got off the phone with Telus and what they told me is that they are releasing ANOTHER TP2 on the GSM network and that I would have to buy another phone TP2 just to get onto the GSM network.
This being said, is there any way to modify the radio signal in my CDMA phone to read both CDMA and GSM, or atleast get more speed out of my phone for connectivity to the net?
*update
I just got off the phone with HTC and the lady I spoke with told me, that to change the radio frequency I just had to change the ROM. That being said IF, I put a Telus HSPA ROM on there the phone should be capable of working on the network. Now that being said. If this is possible would it not be possible to run on both networks, CDMA and HSPA, making the signal control software dependent, meaning I have CDMA controls for standard phone calls and HSPA for running the highspeed network?
Update in previous post.
Eazy, just HardSPL and security unlock your radio bro...Only then you can use the GSM networks in your country (I'm guessing it's US)
But you can only activate one at a time. Either GSM only or CDMA only..CMIIW..
Just my 2 cents
Actually it's Canada
Right but if I unlock the phone, and switch it back and forth on and off the networks, how would that affect my account, could I hide the fact i was doing this?

I have this phone on Telus...I got it unlocked and I put my work sim card in this phone and it's on rogers. I switch networks when necessary....If you get a Telus sim card you would be able to use it GSM.
You should be able to pick which network you use. I saw it in phone settings, I think.

TELUS does not provide GSM at all. They are CDMA and UMTS.
So does this mean its possible. If i have a CDMA Sprint HTC Touch pro 2. That i have the potential of using it on At&t in the US?? All i have to do is unlock it?? Any information would be greatly appreciated.. Thanks!!
And if one does unlock a radio on said Telus phone, can one use both radio frequencies, thus enabling both CDMA and HSPA frequencies?

So Telus new 3G network is not GSM? It does have drop down menu showing "Send SMS over" GMS and CDMA. GSM is selected by default.

[Q] GSM 1700/2100 Question

I'm having trouble finding a definitive answer to this so hopefully someone knows about this stuff. My carrier uses SIM technology and it's 3G uses 1700 and 2100 bands. I'm wanting to find out which of the newer/higher end android phones I could use for their service and actually be able to use both bands. Any help would be greatly appreciated! Thanks!

Those are T-Mobile bands so you are more fortunate than me. You can use the amazing new HTC Sensation with those bands. Unfortunately my carrier, AT&T, doesn't use those bands and I'm not able to yet get a Sensation. You can pretty much choose any T-Mobile phone. They have LG GX2, Samsung Galaxy S 4G and the HTC Sensation and the Sensation is HTC's flagship phone and highly valued.
Like he said, basically any T-Mobile 3G device will work for you.
I notice most of their phones don't have 1700 listed on their bands though. Does that mean I can or can't use them?

Yes, you can use them with full 3G speed...4G if your service provides it.
By the way, you'll need to unlock any T-Mobile branded phone. Simple to do just by calling T-Mobile CS for the sim unlock code.
So the phone I buy just needs to have either one of the two 3g bands I take it? I guess I screwed up because I bought an unlocked Inspire off eBay and when I put my sim card in I got no data at all, not even edge. So if I was to find an Incredible S unlocked I could use that correct?

Well...Edge isn't locked down like HSPA (3G) is. As long as the phone is a GSM version, Edge should work fine, if the service is putting it out. What you likely are needing to do with your Inspire is input the proper APN settings. And also make sure the mobile data is enabled.
Go to "Setting" > "Wireless and Networks" > "Mobile settings" and see if the top box is checked. If not, check it. Then, still in that same menu, go to "Access Point Names" and see what is there. If there isn't an APN there relating to your carrier, make one by tapping the menu button and choosing new APN. Input the correct carrier values from the list in the link below. Once done, tap the menu button and choose "Save". Make sure that new APN you just created is selected...usually a small green dot to the right side of it.

I told you wrong for the Inspire about the menu system. I just booted mine up and had a look. You will find the data checkbox in "Settings" > "Wireless and Networks" labeled "Mobile network".

The company I'm trying to use this with is called iWireless. They aren't on that list but I had found the apn settings by googling it and I did input them just as you suggested and selected them with the little green dot and no such luck. I even rebooted the phone twice. I'm sad cuz I love the Inspire, I rooted it and put a Sense 3D rom on it that I'm in love with. I want to stay with the carrier though cause they have the cheapest thing around, $50 a month unlimited everything including minutes, data, mms & sms. Can't beat it. But there's not many devices as well supported as the Inspire and I really can't stand anything but HTC after having a Motorola Cliq and Samsung Epic both of which I hated.

Yeah I did use those same settings on my Inspire and no such luck. I did just happen to run across this on the iWireless website however.
"Will any 3G GSM phones get 3G speeds on the i wireless 3G network?
No. Our 3G network will only support AWS/UMTS 1700/2100 banded phones. 3G devices that only have the 2100 band will not be compatible on our 3G network."
http://www.iwireless.com/promoform.asp?promo=3G
So am I wrong in taking that to mean that whatever phone I buy actually has to support both 1700 and 2100 bands in order for me to get 3G upload and download speeds? If so my options will be very limited I'm sure. :\
Okay, so from what I've learned between reading and what you've told me and what I know I want I've pretty much come to the conclusion that I'm gonna want an Incredible S or a Sensation as those are pretty much the only HTC phones that appear to cover 2100 (band 1) and 1700/2100 (band 4) which is what I believe that I need. Tell me if you think I'm wrong.

Strange. That seems to be really locked down. I really can't advise you reliably. I do know that T-Mobile uses the 1700/2100 frequencies and that the Sensation, with only the 2100 portion, will work on it. If your network requires both bands, anything I say might lead you in error. Sorry for the lack of help.

It sounds like iWireless may not support AWS bands though, 1700/2100 is what they use, but doesn't necessarily mean it's AWS.
GSM bands will work without issue, assuming the device is unlocked.

Ummmmm...Rogers is GSM and the Verizon Galaxy Nexus is CDMA. You can't change it. You can't use a CDMA phone on a GSM network. You can't do it with any Verizon or Sprint phone (besides their global phones). The phone is useless to you. The GSM model ships factory unlocked.
Thanks for your reply, this phone is really confusing to me because unlike all CDMA phones it still accept micro-SIM card. and in network mode it asked me to select LTE/CDMA ..could you please tell me why it is saying LTE ?

Verizon uses LTE technology as well.

[Q] AT&T One X in India (3G)

Hi all,
i have an unlocked at&t one x. i'm using it in india on vodafone network. i wanted to know if 3g will work on this phone? i see the E symbol on the notification bar. does that mean that it will work only on edge? the frequency bands seem to be compatible. is there anyone who is already using it on the same network and can help me out with this? thanks.

Did 3G ever worked for you ? How did you unlock you AT&T one x, sung unlock code ?
If you go to your dialer and type in *#*#4636#*#* , you will go into testing mode - where you can check your network settings. Verify that your network is not set to something like "LTE Only" (which is not available in India).
Preferably set it to "WCDMA Preferred" or "WCDMA Only" (You can also play around with HSPA ).
See if that works.

this should be in Q&A section.
Are you having any 3G plan from vodafone? - If you are on 3g plan you should get 3g automatically.
-Try changing network modes if you have a 3g plan but still get edge only
Having the same problem..
I have an AT&T Unlocked HTC ONE XL (Eviita)
Its Bands seem to be compatible with 3G Bands in India.
I have tried everything (*#*#4636#*#*) and tried all banks.. on "WCDMA PREFERRED" it still shows "E" and my sim comes 3G data plan is active.
I have Unlocked Bootloader, S-Off, Rooted, Installed Cynganemod 10.2 (Android 4.3) with G-apps and its all working fine, but still no 3G.
Any help on this from anyone.
Theres only 1 thing i can now think of... when u go into (*#*#4636#*#*) mode and click on Phone Information and scroll down, u can see one tab which cannot be clicked and it dimmed out, it says... "OEM-specific Info/Settings", but you cant click it.
Is this a Data Locked phone?

When buying any phone from a source other than your carrier, you need to do the research on band compatibility BEFORE you buy the phone. As this is set in hardware, and is can't be modified. The fact you say "seems to be compatible" implies that you aren't sure.
Also, you haven't mentioned what carrier you are using. The OP says Vodaphone, and I can't find any info on what MHz band Vodaphone uses for 3G. You need to know what band your carrier is using for 3G. Your carrier needs to be using one of the bands 850, 1900, or 2100 MHz for 3G (HSPA). Otherwise you will not get 3G on this device.

That doesn't mean anything, did you make that up? Either the phone is SIM unlocked or not. There is no "lock" on the device that would make you get EDGE but not 3G. Getting EDGE but no 3G typically means that the device is not compatible with your carrier's 3G network.

[Q] Can't turn on 1700 band

Hi All
I have a problem, and don't really know that to do. I have a Samsung Galaxy S Relay 4g, rooted, running the latest nightly and modem. Recently I went on vacation to Europe and while there used local sim cards from t-mobile Eu. At first nothing worked, Then I read some forums and from there learned of the *#*#4636#*#* code. Used the Select Radio Band option and switched to the Euro band selection. All was well Europe SIM cards worked Data, voice everything.
I get back to Canada, and I figure I need to switch back to the USA band. So I do. but still no service, no voice or data. I can get roaming. but that's not really an option. I see the network operators Bell and Rogers, but no Wind or Mobilicity(who use the 1700 band). I'm on wind. So to me it looks like the 1700 mhz band is turned off on my phone.
So far I have tried...
Used the *#*#4636#*#* multiple times switching bands...
Tried using the settings menu to select wcdma preferred or global
Re-flashing the modem
Flashing to the newest nightly
Tried a verified good SIM card
Nothing works....
I'm thinking I may have to go back to the stock t mobile software and try to turn on the radio there...
So does anyone have an idea what could be missing? Or how to specifically turn on the 1700 mhz band? The select radio band pop up only has two options Euro band and USA band.
Any help would be greatly appreciated!
Okay!
So I think I'm back up and running, all AWS networks in Canada show up. Haven't tried data or voice, but I'll be doing that on the way home from work...I'll post after if things still don't work...
So these are the steps I took....
1. Using CWM I did a full back up to an SD card.
2. Then using CWM I flashed the stock JB firmware from here http://forum.xda-developers.com/showpost.php?p=41209211&postcount=1
3. In the Dialer app. I dialed *#197328640# navigated through the gsm,lte,wcdma options and set the band selection to automatic.
4. Tested phone on stock to see if it picks up the networks...and it did!
5. Using CWM restored my original cyanogenmod install with all settings and software.
6. Tested network connectivity again, and the networks now show up.
On the way home I'll do some tests with data and voice.
Looks like everything works! woot!
It looks like there's a bug in the band selection code. It should be offering you the AWS frequencies, as well an an automatic everything choice.
I'll look into a fix for apexqtmo. In addition, I will nuke the CDMA options, they're not needed and probably causing other problems.
