Question with the Samsung 3G and 4G LTD Network Extender

[Mr-Shredder]

Hello,

I have Samsung Note 3.  My bedroom does not receive either voice or text signals very well.

The Samsung SCS-2U01 says it supports the Note 3 but the 4G LTE SLS-BU103 says it supports 4G LTE which, on my phone screen says that I have.

Two questions:

1.)  Besides voice and data, can either of these extenders also be used to text messaging? 

2.)  I've read that I may not be able to use the SLS-BU103 on my Note 3.  Is this true or not?

Thank you.

The 4G extender only supports VoLTE calls I believe. I don't know if the note 3 supports VoLTE.
