Hi,

1. Yes, you can keep your old number for free.

2. I will select auto termination during registration, however, this is your contractor's job to terminate it.
If your contractor do not want to terminate for you, you will need to go to TM point.
*Remind your contract on termination job when they go to install Unifi for you*

3. Yup, for the last four digits. But, it depends on the availability. So, please give me a few choices to choose

Thank you.

You've used it even 1 day of the line, you'll be charged RM 25 for one month only.
Hahaha, super beautiful number will not be available since so many ppl will want this and already taken by others.
**88 can try to search
Since contractor just pulled the infrastructure, it Won't be so fast open for registration. 
No worries, my pleasure to answer your doubt ^^

But, I can check for you to confirm 
Please PM me your address
