MSISDN Info
Call 611 from your NEW line (New being the keyword)
Tell them you want to "MSISDN REUSE" (pronounced 'mizzdin') your old OOC number to the new number (MSISDN = Mobile Station International Subscriber Directory Number)
They will understand what you want when you tell them about "MSISDN REUSE"
Your old number will be disconnected immediatly (Cancel the line), they will do it.
The new number will get a message stating your number has been changed to the old number.
MSISDN REUSE DOES NOT void your rebate despite what any CSRs tell you over the phone. Many people have submitted their rebates and received their rebate, regardless of whether you perform the MSISDN REUSE before or after you submit the rebate.
