Hi @mamachill,
Welcome back to our Community Forums! Thank you for your post and I'm sorry to hear that you're experiencing some issues with a SIM card! I can understand that this can cause some unnecessary stress and we'll do all we can to help resolve this issue for you.
Is your current Mobile SIM linked to a cable account? Can you tell us if you've recently taken out a new cable package at all, that could impact your SIM?
When did you receive the first email about this new SIM card?
Let us know so we can look into this further for you.
Thank you.
