Second property/account

Hi all. Firstly please note that I am 61 years old and not very IT savvy. I have Ring products at home and they work fine through WiFi. However, I also have a second premises that i use for storage. At the moment there is no mains power and no Internet in place..I have a spare cellphone with a high capacity GB data sim account and a high capacity solar assisted power bank to power it and these items I hope can be used in lieu of WiFi..QUESTION Can I use the phone in conjunction with a (battery) Ring camera , and if so , how could I view images remotely on my own regular smartphone ? Do i need a second Ring account and email address etc.. Any advice would be much appreciated.
