Optimus 7 and Tmobile

So, I just bought this phone - I like the way it looks, and I wanted to try out WP7.
Unfortunately, I'm not sure how to get it working with tmobile (I live in the US)
It's a LG E-900h, with the canadian telus firmware on it. What do I need to do if I want to use it with Tmobile?

Let's start with what is not working for you. Can you at least make phone calls? Give us some details.

phone calls
Nope - Can't make phone calls - right now, the phone tells me my SIM card is invalid (in settings/cellular, it says "no sim")
I assume this can be fixed - but the methods I've tried haven't worked (I've tried debranding via the engineering menu, and swapping to the tmobile network profile)
Is there anything else I should try?

Its odd that it says No SIM, I'd figure it would at least ask you for an unlock code. Are you sure you have the SIM in the correct way? If you put them in backwards, the phone won't read it.
If your phone then asks for an unlock code, you'll need to SIM unlock it.

From this post http://forum.xda-developers.com/showthread.php?p=9827632#post9827632 :
Unfortunately, LG Optimus 7 does not support AWS, hence it will not support 3G neither on T-Mobile USA nor Wind Mobile or Mobilicity (it will fall back to GSM/EDGE modes on T-Mobile and will always be in Wind Away zone roaming through Rogers if you were to use Wind Mobile SIM card).
Not to stop you short, but just a heads up I guess.
If you go into the MFG settings to change the network profile thare are a couple that show "TMU_US" thought I'm not sure if that's even TMobile or what carrier that would be or even which one to try. But good luck.

yep
I saw that thread before hand, and I was anticipating the 3g problem (a tmobile rep had told me this as well)
My issue is making phone calls ATM. everyone else says when you insert a foreign sim, it asks for an unlock code - which mine hasn't done yet. I did buy the phone used on ebay (the seller claimed it was unlocked).
Regardless - right now, it says invalid sim. I inserted it with the notched corner UP
**SURE ENOUGH - sim card was in backwards. it's working great now

Don't feel bad, I forgot about that, but I did the same thing.
So use to haveing it only fit one way that I didn't pay attention to the picture, but I got it working after a litle while too.
Let us know how the connections are working out for you.

I have a Telus LG Optimus 7 phone, bought an unlock code on eBay for $10. When going down to US I use a TMO SIM card, and I can confirm that phone works perfectly for 2/2.5G (GSM/EDGE), and doesn't work with TMO 3G (which is AWS, same as Wind Mobile and Mobilicity, like someone mentioned above). But luckily for me TM has a $2/day plan which offers unlimited calls/text/2G internet, which makes it perfect for 1-2 day intermittent trips across the border, EDGE speeds are just enough to have my e-mails coming and maps working. It would support full 3G on AT&T, but they don't have any good prepaid data plans - the only one they could offer was 100 mb for $20, which expires in 7 days.

optimus 3g
are you sure that there's no way to change settings in the engineering menu to make it work with Tmo's 3g?
Also - what do I need to do to update my optimus to the new build of wp7?

I'm absolutely certain - you can manually switch between supported frequencies: WCDMA 850 MHz, WCDMA 900 MHz, WCDMA 1800 MHz and WCDMA 1900 MHz, but the phone has no support for AWS 1700/2100 (unlike regular WCDMA, when uplink and downlink use channels from the same band, AWS is also using different band for upstream and downstream).

When you say "new build" what exactly do you mean? Which build do you currently have? Does Zune tell you that you have latest firmware?

Question to those who have their S4 _successfully_ unlocked by Sprint

Did you received any sort of OTA when Sprint unlocked your phone?
Currently Sprint claims that they just mark the phone as unlocked in their DB and then you need to restart it.
It clearly doesn't work for many, the phone still shows "Invalid SIM" message and the consensus is that this is not normal and the phone is not unlocked.
So the question for those who have their phones _successfully_ unlocked, was there anything in addition to Sprint saying that they unlocked your phone?

when sprint unlocked my phone? I don't follow?

You call them (or chat) and ask to unlock the phone to be used with 3rd party GSM carriers. That's what I meant.

I don't know if my phone has been successfully unlocked - but I can swap in a US T-mo Sim and it doesn't show an Invalid SIM message on my phone.
I only got an Email from InternationalDeviceUnlock <[email protected]> with the following message
Hello xxxxx xxxxxx
This email is intended to confirm that Sprint has successfully unlocked your Samsung Galaxy s4 Device. Please follow the steps below to unlock the device after you have the third party SIM:
Turn off device > Insert 3rd party SIM > go to Settings > More (tab) > System Update > UICC unlock. You will receive the update and it should change to GSM Mode.

So did the phone actually do the above?

it wont work on tmobile
tmobile is on different bandwidths when they say unlock they mean international not any us carriers and even if it did work you would only get edge no 3g or lte

no, tmobile and att bands are supported by the hardware.. but are blocked by samsung/sprint regardless of unlocked sim status. if we can unblock it 3G would also be supported. WCDMA band support on the Sprint GS4 includes 850mhz and 1900mhz... so that means 3G works just about everywhere for ATT... and Tmobile would have no AWS band support but would have 3G in areas where Tmobile has refarmed 1900mhz.
Again.. the hardware itself supports these bands... its just an extra block thats stopping us. I am working on the unblock for ATT/Tmobile.
And to the OP @obender, @jj14's post show exactly what Sprint sends when the device is unlocked. Other than that... go thru the steps and that's that. As jj14 also states.. he can pop in a tmo sim and gets no error... proving he is truly unlocked.

I had my phone unlocked, and I did the above as per the email I received. However it just said that the profile had been successfully updated, which was the same thing it said before it was supposedly unlocked when I pressed UICC unlock. It also didn't change to GSM mode automatically. So I wasn't really sure it had worked, but I was able to put in the AT&T SIM from my Nexus 7 and I didn't get an invalid SIM error.
When I went to Costa Rica, I was successfully able to use my phone with a prepaid SIM (GSM and HSPA/WCDMA). That said, I had to go into the Testing menu and force it to use only WCDMA, otherwise it would only use GSM/EDGE (even selecting WCDMA preferred didn't work... it would switch back to GSM pretty quickly). I also had to make a build.prop edit to be able to add an APN to use data. So you basically need root if you want to use data.

I don't know - because I was still in the US and using a SIM from US based T-Mo

You seem to be digging in the unlock for the S4, but are you just working on domestic, or also international unlock. Have anyone tried pulling all the nv items before and after the unlock?

I just recently got my S4 from sprint I had them unlock it for international use all the available networks now show up, but in regards to invalid sim msg I will not know till the end of September when i am out of country. and on a side note if you call Sprint before you own the phone for less than 90 days you have to go through a lot of loops but they will unlock it for international use. out side of that I am unsure as too how far the unlock actually goes.
will keep you updated as to my findings I will be trying a different sim card while over there

Thanks for the info, im going out of country soon and was wondering how you do the "build.Prop" Edit to edit the APN.
Thanks

Force LTE on for N9005

Hi there -
I'm informed that the Note 3 checks the sim at boot, and disables LTE for carriers that don't actually offer it. My carrier in New Zealand launched their LTE network a couple of days ago, but the Note still won't enable LTE (apparently because it's just checking the carrier on the Sim against a list of "verified LTE" carriers provided by Samsung).
Is there any way to override this checking and force the Note to enable LTE, despite the fact my carrier isn't on their list?
Extra info: The phone works fine on LTE networks with other sims inserted (ie, Australia on Optus)

Hey man, i registered just to answer this for you,
I've been having the same problem, getting the Note 3 and on Telecom, not being able to get 4g on my phone, was on call with them for 30 minutes with them telling me i have to download the latest update (which i already have).
Anyway, download this app called VIAERO in the app store,
It'll let you force set 4G on your phone, getting 55mbits down 22 mbits up, woooo

[Q] No Data Connectivity SM-G900F in Canada

Hey everyone,
I have a s5 that i bought in Greece while i was there. i have used it in Greece, Istanbul, and Spain with no problems, however when i returned to Canada i cant seem to get it to connect to the data network here. I am on Fido and i have tried all the various APN configurations that i could find on their support site. i have even left the phone with the store for a few hours to try and get it working and they had no luck. i know that its not teh network or the sim card because i have tried the sim card in a few other phones and it works fine.
Now this is the part that is somewhat confusing to me, I can call and sent text messages.... but anything that requires data, no dice.....
Anyone have any ideas?
Samsung support has been no help BTW. as soon as they see that its a European device they essentially say Oh, i dont have to do anything, call Samsung Europe... obviously that would be a really expensive call.

I had a similar problem with my S3 before and the way I fixed it was to find the correct APN settings and create a new APN setting page and fill it out, dont edit one that is already given to you but create another one and fill it with the correct apn settings which you can get from the fido stores. Have you had any problems with calling and receiving calls ? Let me know if this works.

i have done everything that i can think of as far as apn settings goes. i have reset to default apn settings, delete all the apns, and manually entered ones from customer service, deleted those and nothing... it seems like its an apn related problem, because i can see the network. in the about phone and status section i can see that there is an LTE network available, but my phone just doesnt want to connect to it..... ARGHHH

Does your provider use the 2600 frequency (band 7) where you live?, if not you can`t get 4G mate because the rest of the Canadian bands are not supported bij the G900F.

i get that, but im not getting ANY data. i should at the very least get 3G. the 900F has both of Fido's GSM bands 850, 1900

Did you try a friends simcard?, maybe yours is faulty somehow. Or maybe a data factory reset/reflash the stock rom may solve the issue.

Sorry, i kinda posted this like a noob would. i should have known better. i have tried the sim card in my old phone that i had before a samsung galaxy s2 skyrocket and it works fine.
I just posted this on the fido forums.
Hey everyone,
I have a samsung galaxy s5 that i bought in Greece and i am not able to get it to connect to the Data network of fido for some reason. i am completly stumped as to why. i paid quite a bit for it so it would really suck to get it home to canada and not be able to use it,..
So, before i get suggestions on things to do that i have already done, BEFORE i bought the SM-G900F (European factory unlocked and not region locked) i made sure that the bands would match up on the phone. its pretty much impossible to buy a phone that wont work in north america anymore. LTE is the only big question, but fido uses B1 and the phone has it.
I have used the phone with no issues in Greece where i purchased it, and also in Istanbul, italy, and Japan. I first thought that it was an APN setting issue, but i have been down every route as far as APN settings go. i have reset the apn settings to default on the sim card, nothing, i have manually entered the apn settings from the "how to configure an unlocked phone page" on this site and nothing, i have deleted all the apns manually then only entered the one APN for internet and mms, nothing.
after that didnt work i took thinks to the next level and did a factory data reset and still nothing.... then i took it one level further and re-installed the phones firmware right from baseline by pluging it into kies on the computer and download mode and all that good stuff..... nothing.
The strange part is that i know that the phone can see the network, because if you go under about phone and status, it will show the available network type, be it LTE or WCDMA, it simply says network status "disconnected"
I can send and recieve calls and SMS messages, but no data what so ever, mms, or internet.
PLEASE HELP!!!

Will S7 Edge SM-G9350 Dual Sim work fully on AT&T?

I bought an S7 Edge SM-G9350 Dual Sim that is unlocked. I was planning on using it on AT&T but apparently the Dual Sim model isn't compatible with the 4G LTE in the US. The AT&T rep I worked with called his Samsung rep and verified it wouldn't work on 4G. We checked all the APN settings and bands the device is capable of, verifying it should work. Is there any way to make it work correctly as it seems to be a software issue?
I spoke with another AT&T rep who said it doesn't appear to have the region lock as it wouldn't activate on the AT&T network at all then but he didn't know why it wouldn't work. From the article I read the region lock is separate from the network lock. The region lock is removed if a phone call of 5 min is made in the area the phone is from. Then the region lock is deactivated. Here is the article I found. www . androidcentral.com/your-unlocked-euro-galaxy-s7-still-region-locked-thats-not-huge-deal
Would flashing another ROM work, or what level is the incompatibility? In the network settings there are listings for the carriers and their 2G and 3G settings but nothing else.

Apparently this thread double posted so this one can be deleted by a Mod

really... i'm calling BS on the reps... what is your definition of "working fully"? i have a dual sim G935FD and LTE works just fine on AT&T. the international version is missing 2 bands (29 and 30?), that's used in certain areas. other than that, i personally have not had any issues/ have you tried using an AT&T sim to confirm the phone won't work, use LTE? see below as well (WillMyPhoneWork.net):
