I want to port my number from telekom to O2

Hello Team,

I have a contract with O2 and i want my O2 number to be ported to my previous number from Deutsch telekom. Currently my contract with Deustch is expired and my number is not usable, so i want this to be done as soon as possible.

Below are the details:

My old number from telekom: +XXXXXX

My current number from O2: +XXXXX

my request: My O2 number should be changed to my old number .

+XXXXX→ +XXXXXX

Since the number is already deactivated , i stopped getting all the calls, please take this request on highest priority and help me port the number.

Thanks,

Arjun
