Hi @santosh, 

welcome to our English Community. 

I regret that you would like to leave us. But of course, I will help you to release your number for transfer to another provider. 

I will send you in a few minutes a private message via @o2_Support. Please have a look there and reply to my message. 

Loving greetings,

Tobias

Hi @santosh, 

until now, I did not get any response from you at @o2_Support. 

Is your request already clarified?

If you need further support, just let me know. 

Loving greetings,

Tobias

Not yet I am still waiting for your response

Hi @santosh, 

I have just replied at @o2_Support. Just have a look. 

Loving greetings,

Hi @santosh, 

thanks for all your messages at @o2_Support. 

We found out together that you do not have any possibility anymore to port your old mobile phone number to another provider. 

I regret that I cannot offer you any solution for your issue. 

Loving greetings,

Tobias
