Help - Samsung Galaxy S10+ Questions & Answers

I have a sprint galaxy s10 + (SM-G975U) RELEASED BY THE COMPANY. The thing is that where I live, the signal from my current telephony does not pick up well (at & t) The sprint customization layer does not leave me with good signal connectivity
I saw on the internet that the SM-G975U version of cell phone IS THE SAME FOR ANY COMPANY
My question is:
If I flash the system and put SO of the T-mobile company, do you think I can solve my problem with the signal and data network?
Tengo un galaxy s10 + de sprint (SM-G975U) LIBERADO POR LA COMPAÑÍA. La cosa es que donde vivo no me levanta bien la señal de mi telefonía actual (at&t) La capa de personalización de sprint no me deja buena conectividad de señal
Vi en la internet que la version SM-G975U de celular ES LA MISMA PARA CUALQUIER COMPAÑIA
Mi pregunta es:
¿Si flasheo el sistema y pongo SO el de la empresa T- mobile creen que pueda solucionar mi problema con la señal y red de datos?

I don't think Sprint or T-Mobile firmware changes the bands your phone can connect to. Do you get better AT&T reception on another phone? Where I live the AT&T signal is bad no matter what phone you use--and I live in a large city. When I had AT&T I couldn't make or receive calls in half the rooms in my apartment--but I never had similar signal issues on Sprint, T-Mobile or Verizon.

Telcel 3g WM 6.1 Hell...

So get this, I buy an LG CT810 in NYC, unlock it and bring it to Mexico to use it with Telcel, YOU GUESSED IT!, it won`t connect to the internet, so I took it to the Telcel tecnical service Einsteins only to notice that I knew more about my problem than they did, however I`m still unable to solve the situation. My windows Mobile Version is 6.1. I bumped into a thread that explained how to configure The Telcel 3G service on a WM Phone, but that must be for older versions, is there a tutorial somewhere?, can anyone help me with the most recent version?, would be much appreciated!.
Cheers!
Pues bien, imaginense esto, compre un telefono LG CT810 en Estados Unidos, lo desbloquee y lo traje a Mexico para usarlo con Telcel, y como se podran imaginar el telefono no tiene servicio de internet, asi que lo lleve con los Genios de soporte tecnico en Telcel solo para darme cuenta que yo se mas de mi problema que ellos, aun asi no he podido resolver mi situacion. La version de Windows Mobile que usa mi nuevo telefono es 6.1. Me encontre con un Thread sobre como configurar telefonos con WM en la red 3G de Telcel, pero parece usar una version anterior de WM. Puede alguien ayudarme a configurar la ultima version?, hay algun tutorial?, cualquier ayuda sera muy agradecida!,
Salud!

Xperia Skype Telcel Mexico

Adivinen que, al parecer RaTELCEL, ya bloquea Skype, hace algunos días que dejó de funcionar específicamente con 3G, puedo conectarme con Wifi o con USB (usando internet de PC).
Por favor, en iPhone alguien sacó una aplicacion para darle la vuelta a la restricción, alguien sabe como arreglar esto en Windows Mobile 6.1 o el Xperia?
No permitamos que RaTelcel bloquee programas como estos, la verdad osea no estamos obligados a usar su estupido servicio de telefonia, que no les basta con pagar un buen con su renta de internet?
Saludos, ojalá puedan ayudar.

It seems that Telcel (Mexican mobile provider) started to block Skype, few days ago the software stop working especifically with 3G, I still can connect trough Wifi or USB (using pc internet).
There's a patch for the iPhone to cheat this restriction, is there one for Windows Mobile 6.1? or Xperia?
We should not allow any company to be able to restrict stuff like this, isn't enough the ammount we pay for unlimited internet? We should not be forced to use their phone services thats up to us. I hope someone can help on this issue, THANKS.
And please, it's very common for some users to answer a little aggresive to other users that sometimes write something dumb, not everyone stays sit on a computer most part of the day, please, just reply kindly something to help, not just something that is another waste of time.

that isn't the issue, and that was pretty offensive.
the issue is this is an English speaking forum, English only.
"4. Use the English language.
We understand that with all the different nationalities not everyone speaks English well, but please try. If you're really unable to post in English use an online translator, You're free to include your original message in your own language below the English translation."
so by not writing it in English first, you waste other peoples time.
as for your question, try setting it up through a proxy? besides that, no idea.
Thanks ibeQuint
Sorry about that comment, but i was answering the user about HIS OFFENSIVE comment. "Learn english first!".
----------------------
Actually the application works perfect, i can still connect trough Wifi or USB, its just not working with 3G, I think Telcel (Mexico provider) its blocking VoIP services trough their network.
As for iPhone, theres a patch for skype to make it think, your are trough other network, i would like to know if theres something similar for Xperia.

I hardly find that offensive, you seem to perpectly speak english yet the fact that this is an english speaking community totally escapes you?
Furthermore, insisting that Spanish is supposed to be a second language to everyone is very shortsighted. For a lot of people (including me) English IS the second language.
I had the same problem

"lost" on my demand - Perdi la demanda
English:
Ill resumen this in english, basically i lost the demand, they came very prepotent saying they dont care of me or any other customer, and that there will not any negociation.
They arguments was that this "sites" (He didnt mention ports or apps) could not be free, so they decided to block em. I told him that as my contract was before this blocking, i had the right to decide not on this service changes, so i had the right to cancel my contract without paying cancelation fee. They anyway rejected my offer.
How ever, as they did never mention the changes to anyone, they were subjects of an infraction, cuz in mexican laws theres one that says that its mandatory to tell the people by at least 1 way. (Internet, Tv, prints, etc)
That helped me to make a "negociation". I asked him to let me change to the cheapest plan, he agreed but charging me $2,800 pesos (250usd), i told him to consider i was his customer and had other lines, he accpeted only by 1800 (150usd).
So what is supposed to do, is to demand them over Cofetel, since they are the institution that allow their contract to be authoriced. Maybe them can ask for more, i just placed mine there.
Spanish:
Les anexo mi resolución ante la demanda impuesta contra Telcel (operador movil de Mexico).
Pues tecnicamente por así decirlo, perdi.
El representante de telcel llegó muy prepotente sin intención alguna de negociar, el llego diciendo básicamente que no le interesaba y que no habría negociación y que podía hacerle como quisiera y subir la demanda a otro rollo. Jamas tomo en cuenta o le importo que yo era su cliente, y no solo de esa linea sino de otras 2 que le dan 3,000 mensuales desde hace 8 años.
Parte de sus argumentos eran que "Telcel no puede garantizar que estas paginas sean gratis, por lo tanto por politica se bloquearon" Mencione y explique que eso fue despues de mi contrato y que ademas no me avisaron. Y que ademas no me importa y yo creo que a nadie, que sea gratis o no, es un argumento estupido, pero como tenian que decir algo, pues se fueron por la orillita para segun ellos que no nos demos cuenta, pero hasta la abogada de la profeco se reia y decia que eso no arreglaba nada.
Fue lo único de lo que me pude agarrar, como no avisaron y obviamente no tienen el aviso, se hacen acredores a una multa aunque respecto a mi caso no ocurre ningun cambio, pero la posibilidad de pagar esa multa me ayudo a que medio me escuchara, y llegamos al acuerdo de que como ya no me sirve el plan me dejara cambiar al mas barato ($189 mixto). Aun asi el hijo de perra me queria cobrar 2800 por el cambio. Total termino en 1800, despues de hablar horas y casi rogarle.
Asi que lo demande, y termine pagando 1800 y para colmo sin poder cancelar, asi que tendre que pagar 189 mensuales por 6 meses mas.
Por lo que te sugiero, si vas a demandar tambien con la profeco, quejate de todo, pero sobre todo de que nunca te avisaron y que no te dieron la legal y mencionada oportunidad en su contrato, de poder recindir por ese cambio de condiciones del servicio. Con esto, va a venir a fregarte, pero con la amenaza de la multa podrian llegar a un arreglo.
Otro punto importante por mencionar, es que argumentaba que Profeco no "rige" a telcel, sino la Cofetel, que es quien otorgó el permiso del contrato. Por lo que al mismo tiempo demanda por medio de Cofetel, yo ya levante la mia.
Sugeriria hacerlo en ambas instituciones al mismo tiempo, ya que hay que presionar a Telcel.

Hi Victor. It's very sad to know you're living this. I think this is one of the main reasons Carlos Slim is one of the richest people on earth. If you need help with the sue process you're starting, i'd be glad to join your efforts.
One question, how cheap is to skype the mexican cell users against the telcel regular rates? (and using WiFi?) Is it a good option? I could try North region of Mexico and let you know my thoughts..
Best regards
It's only convenient for landlines. Not cell lines (wireless)

Hi.
For Mexico Skype had a unlimited plan only for landlines in the three major cities: Mexico City, Guadalajara, and Monterrey, (numbers of landlines of these cities). US, (both, cell lines and landlines) and others.
The plan cost EUR 3.95 per month.
If you need to call to wireless line the cost it's a little bit more cheaper than the wireless phone. I prefer using the wireless phone to call a wireless phone. (Better sound quality)
WiFi it's an excellent option, but i repeat, only for call to landlines in the cities mentioned before.
Thanks i'll give it a try. Sound Quality should be ok.
There is always Telcel's official twitter. We can inform people ourselves
I'll start to inform people tomorrow on regular basis. The more we are, the more difficult it will be for them to block us. They are taking advantage of the fact most people don't even know it is possible to make video calls using their cellphones and the internet plan, since Telcel now offers a proprietary software that charges an extra fee for video calls (At a higher fee than regular mobile calls).
Mexican companies are yet to experience the wrath of displeased costumers bashing their poor service and products all over the net, but it is starting to happen.
Anyone interested in joining the crusade could probably help to change this annoying situation.
Of course, you are always welcome to dump Telcel after your contract expires. As far as I know, both movistar and Iusacel still support skype.
For mobile to mobile video calls, take a look at fring
It is free and still works with Telcel. It will probably continue to do so until a lot of people knows about it, but will buy some time while we plague their official social network official pages
Please don't let me die alone.
DP
Well this sucks. I was trying to get skype to work on my wife's X10 mini.
Also has anyone tried using Fring or Tango over the Telcel 3G network?
I tried downloading Fring in the Android Market while in Mexico and I could not find the app.

Preguntas sobre Flash Rom en T-Mo Glaxy Tab.

Saludos Amigos.
Soy de Puerto Rico. Les escribo en español pues no se inglés, para entender los foros uso el traductor de Google, pero cuando lo uso de español a ingles se pierde mucho el sentido de la oración. Espero puedan ayudarme a entender un poco más esto de los ROM en Androide. Tengo una T-Mobile Galaxy Tab Hace unos días. Llevo mucho tiempo cambiando los Roms a mis teléfonos. Comencé con un Tilt de ATT, luego un Pro, luego Pro 2, etc. Ice algunas cosas con el Vibrant, pero no entendía mucho. Pero si me ayudan tal vez pueda ayudar en algo, pues tengo algo de conocimiento en electrónica y comunicaciones.
En ODIN.
1-Que es el PIT y que es lo que hace?
2-Que es el PDA, Creo que se refiere al ROM como tal pues es el archivo de mayor tamaño, pero quiero estar seguro.
3-MODEM es lo mismo que el radio?
4- Que es el CSC y su uso?
5- Que es el DUMP y cuál es su función?
Tengo la versión Euro y corre de maravilla. Le he probado varios MODEM incluyendo el de él VIBRAN Original, pero este hace las llamadas pero se escucha muy bajo el sonido. Tampoco he logrado conseguir data, aunque si tengo plan de data en mi servicio. Sé que el EURO solo corre E y no 3G, pero ni siquiera E. Alguien podría decirme que plan de data de T-Mobile US debo tener con mi plan de voz?
Creo que son muchas preguntas, pero créanme, este foro es mi vida. En ocasiones reinstalo algunos ROM solo por entretenerme, jejejeje Pueden contestar en inglés, no ahy problema.
Dios les bendiga mucho, de verdad son unos genios.
The forum rules clearly state that all posts MUST be made in English.
Try again, dude, before a mod comes in here and smacks you around
Saludos Amigos.
I'm from Puerto Rico. I write in Spanish because it is not English, to understand the forums use the Google translator, but when I use Spanish to English will lose a lot of the meaning of the sentence. I hope you can help me understand a little more that the ROM in Android. T-Mobile I have a few days ago Galaxy Tab. I have long Roms changing my phone. I started with ATT Tilt, then a pro, then Pro 2, etc. Ice some things with the Vibrant, but did not understand much. But if you help me maybe I can help with anything, because I have some knowledge in electronics and communications.
In ODIN.
1-What is the PIT and what it does?
2-What is the PDA, I think it refers to the ROM as such it is the larger file, but I want to be sure.
3-modem is the same as the radio?
4 - What is the CSC and its use?
5 - What is the DUMP and what is its function?
I have the Euro version and runs great. I have tried several modems including the Original VIBRO, but it makes calls but you hear very low sound. Nor have I managed to get data, even if I have a data plan on my service. EURO I know that I just run and not 3G, but even E. Could anyone tell me which data plan from T-Mobile U.S. I have with my voice plan?
I think there are many questions, but believe me, this forum is my life. Sometimes just to reinstall some entertain ROM, jejejeje can answer in English, ahy no problem.
God bless you, really are geniuses.

Could be wrong on some of these but here we go.
1. The PIT file contains partition information. I think.
2. PDA pretty much is the ROM.
3. Yes the modem is the same as the radio.
4. I have no idea what the CSC does. Sorry.
5. I have no idea what DUMP does either.
Right now T-Mobile is filtering the use of certain SIM cards based on the IMEI of the device. I don't know if this is just in certain areas or if they are filtering all service areas but in order to do it here in hell with a SIM card that is on a smart-phone plan you would need to change the IMEI of the device to make it avoid their filter.

It might help to use English here. The little Spanish I understand makes it sound like you want to use a T-Mobile SGS2 on AT&T? I think the SGS2 from T-Mobile has only 1700/2100 and no 1900 UTMS 3G band so it won't happen. If it has the 1900 then you should just need to get the SIM slot unlocked and be good to go.
