Hello @michael_lu,
To your point about data, all our new plans now have the Data Overage Protection, which means you no longer have surprises of going over your data. We block it and offer you options to continue using it. That means that you have the peace of mind of never going over again and you can enjoy full LTE speeds with our new plans. No speed reduction in this case. No compromise on the quality!
Additionally, our plans have Data Bytes which provides you with 5 hours of free data per billing cycle. That's another great way to enjoy data full speed ahead when you're out and about or are looking to use data-intensive apps like streaming or downloading videos.
Of course, we wouldn't want to see you go after all these years and would love to review your options with you. To do so, you can reach out to us through our official customer service channels which you can find here.
Hope this helps put things in perspective and we wish to have an on-going business relation for many years to come.
