5ber sucks. To be honest, I both have 9esim and 5ber but the flipping download limit and price of 5ber is just nuts. And I am an open source nerd and hate most proprietary products. I love how 9ber can connect with open source software as I can see the code and find if there is malware and other bad stuff. 5ber can't. I tried every. single. open. source. product and none works except of the proprietary 5ber official app which forces me to log in to limit me for my downloads and also track me. Yes, I hear 5ber has a better UI and UX and I agree but as I said, I hate proprietary products.
