Buddy, can you watch YouTube and specifically have you changed any settings recently. I would switch it off and on again and re try- failing that a factory reset will get things set back to default settings. Just make sure you back up any info - good luck
The easiest way according to Samsung is to install Samsung Kies, which allows your PC to see the tablet as a USB drive with folder structure.

Hello,
Had a problem very similar to this. I took it to my local servicing agent and they found the SIM Base to be defective. They replaced the section but charged 75 USD (it was out of warranty) then they reinitialized the SIM and all was well.
