What exactly do you mean by "I try to activate my lost number"?
What exactly are you trying to do here and what steps are you taking to do it?
And what otp are you referring to?
If you want assistance from the Community Forum then you'll need to explain/describe your issue more clearly and in more detail.
You seem to have been with 48 since last year so why are you using a new SIM?
If you need to contact 48 support about this then see the links in my signature below.
