Hi @Juanpedrol, welcome to our forum!
Your question has been translated to English as this is an International forum, please post any replies in English.
Do I understand correctly that you want to change your service provider / operator? If that is the case, I would recommend that you get in touch with different operators in your country/region and see which one can offer the best subscription for you! 
Let me know if that helps and I'm sorry if I misunderstood your question.
