Hi, I found it really interesting, but I think you should reduce the number of plans you are offering and eventually offer something like 3 plan, each with a base and price/data capacity and an additional cost per data usage
Seeing something 'jarring' or unexpected triggered a 'what's going on here' response which made me somewhat cautious of what's being offered. The play being extracting the most from the customer rather than delivering the most value like a pushy salesman. In the end sentiments matter less than conversion, but experimenting to see what improves conversion is often dramatically worthwhile. If you've already done so, I'm surprised why this form doesn't show up anywhere else I can recall.
