Greetings and Welcome to JustAnswer.
I am Andrew your Support Technician with over 30 years of experience, it can be very frustrating when electronic devices go wrong but from my experience misconfiguration are usually the problem and they can be quickly resolved with the right advice and assistance. Please allow me a few moments to investigate, I will respond at the earliest either requesting more information or providing further information.
Thank you for your patience while I investigated your question. It sounds like your Samsung device is encountering problems and is unable to receive a 4G Signal, this could down to two reasons, one that the device does not have a strong enough 4G Signal in your area or the settings have been misconfigured on your device which is preventing the handset to connect to your 4G Waveband. I have composed instructions in a step by step format which will assist you to check the settings that have been set on your handset, ensure you review each step before proceeding.
I hope the information provided today helps to restore your Network Connection and if you have any questions or require any further assistance, please let me know and I will do my best to answer those!

Have you attempted to powercycle the device?
