I'm trying to "fix" my reception problem. Love everything about my Note 3 except its inability to connect to a signal in a fringe area, The Note 3 has been replaced once already by Verizon for the reception problem. My previous phone was a Razr Maxx. Verizon is my carrier. The reception issue only affects me in an area that I hunt.(I generally hunt alone and communication is a safety issue) I did a side by side comparison with my Note 3 and a Verizon 4g I pad. Where I had absolutely no signal on the Note 3 I had some 4g on the Ipad and 3g was good. I had used the Razr Maxx in the exact same spot with no problem either voice or text. (An internet search seems to indicate that the Motorola radios have been some of the best performing) I still have the Razr Maxx. Can I charge up the Razr Maxx, insert the Sim card from the Note 3 and use it when I am hunting? If that is possible can I get a duplicate Sim card to keep in the Razr Maxx as long as I don't have both phones turned on at the same time? Will Verizon duplicate the Sim card for me or do I have to buy the duplicating equipment I see on line. Thanks.
