Samsung S20 Ultra failures
Greetings. I bought an S20 ultra phone released at Bestbuy at the beginning of July 2020, in El Paso, TX, the city where I live and installed my Tmobile line.
At first the phone connected to the 5G network, with amazing browsing speeds. For 6 months the Tmobile network presented failures and they recommended that I connect by LTE, since the equipment was "looking for the 5G network" and did not connect to LTE. Since that time I have been working with LTE.
This week, for moving matters, I traveled to Orlando, FL, and because I was in a big city, I switched to 5G, and shortly after connecting the phone informed me that it was not connected to the network. I went to a Tmobile center, located in the Milenium Mall and they changed my SIM card (which they charged me as a Tmobile customer) and the phone began to connect to 5G, but within minutes it disconnected.
When I was in the Florida Mall, my phone was not connected by any network, and I went to a TMobile store, where I was 1 hour, being attended with great professionalism, and they checked all the parameters of my account and the phone, even resetting the network on the phone, and the phone was without internet connection. At the suggestion of the staff I went to BestBUy located on the same avenue but they did not have Technical service and they told me to go to the Bestbuy located at 4601 Colonial Dr. Due to the time I postponed it for the next day.
Upon arriving at the hotel, I made a call to Samsung support, in which they told me to reset all the settings. Indeed, once reset, the phone connected via LTE, but when testing 5G again it did not connect, and when it returned to LTE it did not give connection. I reset all the settings and the phone reconnected via LTE.
Checking in the Samsung Members, they indicate an authorized Samsung center called Ubreakifx, which I went to first thing in the morning, and according to the technician the fault is given by the team due to problems with the antenna, which I wanted to change, but I refused due to that my phone is under warranty.
I went to Bestbuy in Colonial, where they treated me very well, they did a software test and they didn't find any flaws, although I still can't navigate on 5g. They indicate that the fault is from Tmobile.
In short, I lost a day of work, Bestbuy says that the fault is from Tmobile, Tmobile says that it is from Samsung and I cannot enjoy the benefits of my phone.
I require from you some solution. In the city I live in, El Paso TX, there is no Samsung service, and at the end of this month I am moving to Orlando FL
What are your settings at under Settings - Connections - Mobile Networks - Network Mode.
The main problems are some carriers not all. I have Boost Mobile with Sprint as a carrier and other than the weak signal in a concrete walled building, I'm fine. Boost and Sprint respond to any concerns but I don't have concerns because I decided not to switch my Google account messages to Samsung messages. Bottom line.
