Thank you for reaching out to us. We'll be happy to assist you.
If you have prepaid, you can activate your SIM card by calling 800-901-9878. If this is postpaid, unfortunately you'll have to use the website. What exactly do you see on your screen when you go into the activation portal? Are you on a computer or a mobile phone?
