i did try wifi calling for awhile, but that didn't seem to help and was only available whenever i was near a friendly wifi. i tried a booster from the playstore but that was totally ineffective. i guess from lack of response, i should assume the only recourse is to root this device. i just haven't had the time to study the information on how to and which roms, etc were available that appeal to me. i've had Galaxy S3 & 4 for so long the Note was a real switchover.
But thanks for your help.
