International Cloud VoIP Expert: Set up Dutch 06 & Global Lines for Remote Calling & SMS

Project Overview: I am a mystery caller relocating to Paraguay. I need a 100% digital cloud-based VoIP system to make outbound calls and receive incoming SMS. I cannot host physical hardware in the Netherlands. Key Requirements: The Netherlands: I strictly need genuine 06 mobile numbers (no 097/fixed lines). I am a Dutch resident with a valid ID and local subscriptions, but these lines must be bridged digitally to the cloud.International Flexibility: I need to easily buy, use, and deactivate mobile/fixed numbers from The Netherlands and in the future other countries (UK, Germany, USA, etc.) depending on active projects. Nummers will constantly change. Remote Use: Everything must work flawlessly via a softphone app or web dashboard in Paraguay. Your Tasks:Recommend and set up the right Cloud PBX (e.g., 3CX, FreePBX, Zadarma) that combines Dutch 06 lines with international SIP trunks.Configure high-quality voice routing and digital SMS forwarding. Teach a non-developer how to independently add and remove international numbers. Please explain your proposed cloud architecture and which providers you recommend for this setup. Thank you!
