What do I do in this case? My T-Mobile data plan/contract ends before the phone I want comes out and I want to keep my phone number. I do not want pay like 100 euros more for the phone when it comes out on 9 Oct because it's without a contract and then renew my SIM-only contract on 6 Oct.
Any help with this? It's a bit complicated but I can answer any questions to clarify

Check https://www.t-mobile.nl/Consumer/media/pdf/voorwaarden/algemene-voorwaarden-juni-2017.pdf especially part 7 (Looptijd chapter).
If you want to buy at Belsimpel choose your new phone with the option "Mijn eigen 06-nummer meenemen of verlengen" in order to keep your 06 number.
