Signal Issues S6Edge

I have been in contact with a few Samsung stores and have contacted the samsung online chat. The new S6Edge has issues and not just me but so many people at the office and friends and samsung says they are not aware of anything. Last night was just the last. Emergency at home and needed to get hold of a doctor or emergency personal, but the ... phone just had no signal. even after restarting, Really!! I took the Sim out and into my S4 and guess what it worked without any issues. The S6 Edge (1 month old) is now in my bag and has no use to me<br> Can someone from Sasmung please take ownership. <br>
