200 gb data until DSL connection is installed

Dear O2 team,

I am an existing customer of o2(phone contract). and ordered a new DSL connection MyHome m. The technician is going to install it on 30 oct to install DSL connection. How to claim that 200Gb data on the sim that I already have(which came with phone). Or I have to visit the o2 shop again and ask for a new simcard with 200gb data ?

Looking forward for your reply.
