Limited or no network and internet

I am writing this post because I have been contacting Boost Mobile for over a month now, about my new phone the Samsung J7 Perx. I don't know what the problem is but my phone constantly throughout the days loses its network service and my internet and data no longer work. I have to switch my phone on airplane mode all day long or restart my phone to be able to use the internet or network again for a few minutes. In my multiple phone calls to Boost asking them to fix my phone problem, Boost verified that there were no outages in my area and that it must be the phone itself. They had me update he profile under settings, then updates. After doing that my.phone stayed connected to the internet for about a half hour then kept dropping my data all over again. I called Boost back a few days later to speak to then again. This time the told me that I would need to do a complete factory reset to my phone in order for my phone to start working correctly. I expressed to the agent on the phone how badly I did not want to have to reset my phone. The agent again told me this would be the only way to make my phone work correctly. After trying to backup everything on my phone in hopes that I wouldn't lose anything I gave in and factory reset my phone. It turns out that factory resetting my phone did absolutely nothing in fixing the problem it was having. So not only does my phone drop the network and data all day and night long, now I also have some pictures, songs and documents lost due to having to do the reset in the first place. I habe been a loyal Boost Mobile customer for a while now and I am very upset with your company. I pay $50 plus tax every month for unlimited data, calls and messages. But I am clearly not getting the option of using unlimited data because the phone keeps throwing me off the network. I am extremely disappointed in the phone also. I received the J7 Perx from the insurance company due to my original J7 breaking. I was not informed that my phone had been discontinued. So I was sent the Perx as a replacement. I do not think it is fair that I have to pay a full monthly bill when I am not receiving my full phone plan services from your company. I am seriously considering leaving Boost Mobiles service at this time due to this issue that has now turned in to issues. This is the 3rd time I have had Boost as my phone service because I have liked your company so much in the past. I keep coming back as a loyal customer and due to this I am willing to find a new phone company
