Cell Data

To whom this may concern,

Since yesterday morning, my phone is not letting me use any Wi-Fi or even my cell data for anything. My phone can still make and receive calls but when I try to use my apps for example like snapchat, Facebook, tiktok, etc. it says that I have no internet connection.

I have contacted my server that I have service with and they said it could either be my SIM or it is just my phone.

Please help me.
