Hello, I bought a prepaid SIM, put it into a cellphone, and I'm able to make and receive calls just fine. However, I am unable to add it to my account or top up from it. It always tells me that it cannot find the number.
Because of that, I cannot select a data bundle, and as a consequence, I can't use the internet. What do I need to do to be able to link it to my existing account? I don't want to create a new account for it.
Best regards,
Daniel
