I plan to get ip4 for my GF... but i need some clarification from pros:

1. Can I keep the existing Digi prepaid number if change to iDigi 88?
2. Can installment made without credit card? (Debit or bank transfer etc)
3. Is the free quota reset every month?
4. How's the Penang's coverage?

Lastly, based on this site if i go for:
16GB Iphone4 + iDigi 88 + Installment 24mths
Is it RM144.40 + Excessive uses per month?
I keep seeing earlier post where everyone is getting 58/63 bill thingy are those direct purchase without installment?

So based on the 1st question...
So I can straight slot in the old sim card after upgrade?

And for the bill...
So if pay by installment I will get two separate bills?

- 1 Credit Card bill for monthly installment
- 1 Digi bill for monthly charge + extra + 6% govt
