I released my Vodafone number on June 4th and bought a new Telekom card on the 5th, informing the staff that I needed to transfer the number to Telekom. Today I received a text message instructing me to insert the new Telekom SIM card on the 17th to activate the new plan. However, my previous plan doesn't end until November. Can I activate my card at the end of November? If I don't insert the card into my phone, will the activation not be completed? I signed up for a promotional plan, Prepaid M, the one that gives 13GB + 17GB of data.
