@Simfang187, I've learned a long time ago, how to manage my data, and right now, on my 90 day plan, having 12 GB/90 days, I rarely use 6GB total.
I don't do updates via cellular data, I don't stream High Quality music / video, and if I want these things, I do it on WiFi at home, or where ever I can find free WiFi.
You don't need more data - you need to manage what you have better.
They might get our newer plans I’m on there 4+2 so 6 gb a month which is a lot I barely use all of it. They don’t have that plan anymore but keep looking every month at there plans and might be one that comes out.
