3g and baseband in Argentina

Hello everybody. This is my first post and my first aproach into the Android world. I just got 1 day ago my Dinc2 from USA.
I'm from Argentina and I unlocked the phone with a code. I had no problem using the phone for sms and voice calls but when it comes to data connection I can't use it on 3g mode.
I believe that the Verizon ROM has not possibilities to connect to a 3g network in Argentina, so I would like to try another ROM. The problem is that I have to root the phone but I don't know how to deal with the baseband. To be honest I don't completely understand what the baseband is and why do I need to have a special baseband for Argentina, I still must do some research. But I'm very afraid of not being capable of using my 3g data connection EVER. That would make the phone almost useless.... quite sad.
I'd really appreciate if any of you could give me some advice about it.
Thanks a lot.

[Q] i317 4G in Europe?

Hey everyone, I managed to get an SGH-i317. I live in Italy, thus I had to unlock it - through the hidden menu in Android 4.1.1 - to actually make use of it. Now everything radio-related works fine, except for the fact I can't get 4G LTE internet connection. The phone will only reach H+.
I recon this is a problem with i317's modem, as it probably can only interface with AT&T's 4G band, and my guess is using an N7105 modem might address this issue... assuming it is possible to flash an N7105 modem on a i317 with no hassle.
Now, I've tried to look for something about his topic, but the vague answers I found only confused me even more. Might I ask for help, mates?
Cheers.

Confirming my thought, the i317 works on LTE bands 17 and 4, while in my country LTE is only on bands 3, 7 and 20 - which the N7105 supports.
[UPDATE] I just tried flashing an N7105 modem on my i317... no signal whatsoever, reverted back to AT&T...

Any help?

Samsung Galaxy Note 3 NV memory lost

Hi Everyone,
I brought an unlocked galaxy note 3 SM-N9005 from UK to USA, here I got T-mobile service but unfortunately 3G/4G LTE was not working. I thought i might need to put a custom rom in order to solve this issue. I rooted my phone then installed X-Note rom using CWM recovery, but issue still persisted. It made me so upset that even though it's an LTE model but i m unable to use it. Eventually I found a post that says you can enable T-mobile 4G LTE on AT&T Galaxy S4 phones, it took my attention. I followed the same steps in anticipation to get the same results for my note-3 but it was my biggest mistake. Now I am in BIG TROUBLE, it is unable to show any signals, no network and I don't know what to do.
Please help me, I am stuck in the middle of this NV memory and QPST thing. Somebody help me sort this out.
Thanks

The N9005 does not support T-Mobile's frequencies.
No AWS frequency support on that model.

If you flashed the qcn file for an s4 you're hosed. You'll need to find the original one for your model (which has its own forum, btw) and pray it works.

Canadian i747m not working any network in Europe

Hello Everyone
I have Galaxy S3 i747m from Rogers. I went to Europe for holidays. I unlocked my phone in Poland. After that phone was working ok but internet was very slow. It was working on Edge although everywhere was LTE range. I was changing carriers-sim cards but was the same problem. Then I went to UK. There my phone stopped reading any network especially when I was in the building. My current carrier is O2. My phone sometimes says not registered on network or says nothing. I have no connection at all. I dont know what to do now.
I flashed a new rom from this forum Hyperdrive which is nice but it didnt change anything. I was also installing those two files ..modem_XXDME4__ and modem+ddemg2 but my phone stopped working at all. So I had to format and flash a rom again.
Please help me guys because I want to destroy this phone with an AXE. I give up.

Not sure what the situation is in Europe, but I had a similar problem when I bought an unlocked i747M and attempted to use it on my AT&T network in the US.
Phone calls were fine, but way slow data connectivity.
US LTE does not support International/Canadian phones. Something with the modem and bands used here vs Canada.
Might be the same situation where you are. The modem may not be compatible with the European network bands.
I know DocHoliday77 helped me with mine. He made it very clear you CAN NOT change the modem version. I have the US version now and all is fine.

That's the only thing I can think of too tbh. That or something is corrupt or there's some sort of hardware issue. Sorry, I know that doesn't help much.... Hopefully someone else may have thoughts to add...

Unable to connect LG G3 T-Mobile phone to networks in Europe

I recently brought my LG G3 with me to Europe (while on Honeymoon) because I found out from T-Mobile that I could use text and data there at no extra cost. My phone works fine in the United States. But it doesn't find a carrier connection in London; Southampton; Vigo, Spain; Lisbon, Portugal; Cadiz, Spain; Gibraltar; and Barcelona.
I tried my phone in each location and it never connected to anything that wasn't WiFi. That really really sucked. I get that I have it rooted and I am using a different Lollipop ROM than stock. But I didn't think that would prevent it from connecting to towers there.
So what happened? What would be on a fully stock T-Mobile LG G3 that I wouldn't get on my rooted and ROMed version? I'm sure it something simple, but I would really like to know so that I can fix the problem before I go back.

did you turn on roaming?
mine worked great in Paris.
also, if you have really older version of rom

you may need to do this

Worked for me in Paris and Lisbon. I've had some issues when wifi calling is enabled, though. I think there are some very real modem issues but I eventually got it to work.
