Hi Tony26, it's not common practice for carriers to reach out to the millions of clients they have whenever their term ends. Though sometimes on occasion depending on campaigns and promos you might get a text or a promotional call. The onus is always on the client to check their term and look for renewal options.
Contracts and billing can be confusing when dates between the app and the PC site differ by a day for contracts, and sometimes a month or two for payments received. My phone contract has the end date of Oct 11 or 12 2022, depending where you look, but it was paid off Sept 11 // 12, balance went to 0, but my bill right now doesn't reflect that 0, still charging me for the device for another 24 days from today, so one extra device payment when my device balance is 0. So now I have to waste time on a call. It's really annoying.
