Starting a life in Spain

Hi! :)

I just moved to Andalusia with my partner and I have some question on how to start a lie here.

I have heard of Lobster, is it a good mobile phone company? Are they reliable? I have heard they might close because of Brexit but those might just be rumours.

Another is, I have Revolut bank account and I was wondering if they have something similar here in Spain.

Thank you all in advance :)

EDIT: Thank you everyone who made suggestions, it’s very lovely to see such a welcoming community. I hope you all have a great day :D
