So i just bought a galaxy s3 off ebay got it in the mail, put my 4g sim in. But i have no 4g...i know my sims good because i tried it in another phone. I tried restoring to factory using odin, i installed a custom rom and checked my roaming settings and they were all good. Ive 100% wiped multiple times. I am at a loss as to what to do. I can do everything except i have no 4g...only 3g. Any suggestions on how to fix this?
You may need to add the ap info. Go to settings/ more settings/ mobile networks / access point names / click on the apn to view the settings or just manually enter what u see in the pics below. Good luck

Okay. So I bought an unlocked g2x brand new from Amazon. Everything almost works as it should: calling,wifi,texting ....the thing is I cannot send or receive picture messaging.
I spent hours on the phone with T-Mobile (ironically bought an unlocked phone that was originally T-Mobile to use on T-Mobile network. Funny right?) and they say because the imei number is unlocked I am unable to do picture messaging without a data plan. I can't afford a data plan right now.
Anyways I'm hoping there is a way to change the imei number back to being T-Mobile specific. In other words: I want to lock my unlocked phone back to T-Mobile.
All I want is picture messaging. I shouldn't have to have a data plan to achieve this. Can anyone please help?

It shouldn't be your imei, it's your apn settings. Go to settings, wireless, network settings and make sure your apn is set for tmobile.
My phone is unlocked and I send pictures without a data plan. Just remember that you need to have mobile data enabled. It uses data technically, but it's incorporated with your texting plan.

You sir are a genius. That actually fixed my problem.
Now, I have data blocked on my phone so I shouldn't be able to use the data thing even if I tried. ...
I did activate that setting and upon successfully sending a text,the 4g logo does come up where my signal strength and battery are shown. Can you confirm this to be normal? I don't want any extra charges on my next bill....
Sent from my LG-P999 using xda app-developers app
Call them and make sure there's a data block on your phone. You won't get charged. And yes the 4G logo will show when sending an mms.

I spoke with the T Mobile representative. I believe her exact words were : Now you're not supposed to have multimedia messaging on an unlocked phone, But it's changing that setting give you the ability to do so then that is great.
Haha. But yeah she basically is telling me what you guys Are telling me I cannot thank you enough.

I can send mms. But I can't receive them.....any ideas?
Sent from my LG-P999 using xda app-developers app
Data turned on when downloading it? Edit your APN, make sure the APN is set to etc.tmobile.com, mmsc set to mms.msg.t-mobile.com/mms/wapenc, mac set to 310, mnc set to 260

Did you mean to put "Epc.tmobile. " on access point names?
Would I be asking to much for a little help navigating to those particular settings?
Thanks redmonke.
Sent from my LG-P999 using xda app-developers app
Ok after rereading, I see you said to edit my apn, which I assume is short for access point names. Should I edit the only one that is there which is "T-Mobile us, Epc.tmobile. com "
Or should I create a new one?
This is of course assuming that apn is access point names.
Sent from my LG-P999 using xda app-developers app
I did what you suggested, although I had to Create a new apn rather than edit the original because the original will not let me edit it....
After creating the new one, I suspect maybe a miss type in the settings. "Etc " is what I believe you said, but upon using that setting I could no longer send pics.
Once I changed it to "epc " I was able to do so.....
Anyways after creating the new apn as per your suggestion, I noticed that it was an exact mirror of my original apn.
But here's the kicker:
I was able to receive pics so long as my buddy selected to forward it rather than sending it directly (if that makes any sense) .
I then tried to have him compose a fresh message and select a pic to send....to no avail. I also had another friend attempt to do the same only to achieve the same results.
I am having zero issues sending pics.
And so long as data is enabled, I am able to do so.
Its the receiving pics that is giving me the issues.
I don't understand why I can receive forwarded pics....
If anyone can help I suppose I can send my cell number,(with great apprehension) ,via pm to someone who is willing to trouble shoot....

Hm so it looks like you are on the latest version. Did you do a factory reset when you got it?
Sent from my LG-P999 using xda app-developers app
No I didn't...would that somehow lock my phone to a specific carrier?

No but something might be messing up the mms.

Do you think if I installed a newer version of android I would be able to send and receive texts???
Or if I root it?
Sent from my LG-P999 using xda app-developers app
Root no, if a factory restore doesn't then I'd wipe data and install cyanogenmod and see if it works.

so I'm using the Verizon Galaxy S3 in my Country with a CDMA carrier, I'm using CDMA RUIM to connect to the carrier.
The problem is, when im in the EVDO coverage i cannot send SMS (no problem incoming SMS and In/Out Call) to send a sms i must manually change the network to 1xCDMA, is there any fix to this?
Thanks

What ROM are you using? Are you able to send with a 3rd party texting app or same results regardless of what app?

Well the first think i would try is your using the stock is to get off of the stock. Try using synergy rom or something with a bit more network access on the phone side. Untill i can look into it, that's all i can suggest.

Hmmm. Odd that it has no issues with anything but sms. I'll do some research and see what I can find. What country and service if you don't mind me asking?

Im in indonesia, im using a CDMA carrier called "Bakrie Telecom" / "Esia" unlike most of CDMA carrier that "inject" the Number into the handset, this carrier using CDMA RUIM.
When im using Sprints Epic 4G i used the "inject" technique too since that phone do not has a RUIM slot, and its working well.

I would agree with this. Maybe a rom with a little more network access options would help with this.

I'm using an infuse 4g with JB 4.2.1 cm ROM. I unlocked my phone and put in a T-Mobile prepaid sim.
I'm supposed to have 4g consistently but I'm getting 2g(edge), 3g(umts) and on very rare occasions I get 3g(HSDPA)... Its approximately 70%-%20-%10, respectively. And these changes are all happening in the same household. No tower switching.
I only have the option to switch on 2g only in my network mode settings on cm10... APN settings are correct and all T-Mobile can say is that I won't get 4g if the tower doesn't support it..
Are there any possible solutions to obtain 4g at all?
If so, how do I keep it on all the time?
Do I need to install a new modem?
If so, which?
Any comments and/or answers would be greatly appreciated.
Thank you.

Using Uckl2 at the moment. FYI.
Also, I know the modem is for WiFi but does it affect carrier data? If not what can I change to affect my data connection?
Sent from my SGH-I997 using xda app-developers app
I always thought the opposite. I thought modems were only for mobile data. But does switching modems help?
Sent from my SGH-I997 using xda app-developers app
Could increase or decrease your signal and rate at which data is downloaded and uploaded depending on your modem of choice. Battery life is also affected minimally (usually).
Sent from my SGH-I997 using xda app-developers app
Hmm, didn't know that... Well thanks for the lesson but have you tried switching modems?
Sent from my SGH-I997 using xda app-developers app
I switched through a couple and uckl2 seems pretty stable but no change on carrier network service.. I want to put on kl3 but I can't find the download.. Not too many options for my phone though.. That I know of.

It might just be your location.

Since I changed to cm10 and switched to T-Mobile sim I have yet to have 4g. Tried where I'm at now and up to 70 miles from here... Very weird. I can't tell if its T-Mobile or the ROM.

Have you had it before on the same phone? Have you tried using another 4g phone?

Yeah I had 4g on it before, on att and on metro. Both while using stock Froyo rom and GB aeon rom.

Weird, it sounds like its the network then
Sent from my SGH-I997 using xda app-developers app
Yeah that's what I'm thinking but when I called T-Mobile, they said that they cannot diagnose a non-tmobile phone. The only info that they can give me is that they assume its my location and possibly the modem but they cannot guarantee switching modems will work. Doubt they hack phones though, Lol
Sent from my SGH-I997 using xda app-developers app
from my recollection..not from experience:
T-mobile or networks other than AT&T will only give you: edge or 3g.
No 4g or hpsa+
to get better than 3g, you need to be on AT&T
When the phone is on "H" I ran a speed test and its pushing 5 to 7 mb download speed. Is that close to 4g?
Any advice on how to stabilize the network?

in settings, more, mobile networks, apn. really, when the sim card goes into the slot and you boot up, the right apn should be there. rarely, youll have to enter them manually. is you plan set up with data, did you call sprint?
