Hi, I'm currently planing to migrate overseas and am currently using the UMobile SP86 plan. As I would need the phone to do SMS notifications like online credit card purchases etc. After doing some thinking I started researching on online there was a few possible prepaid sims that I can port to that would have the 1 year credit validity.

After some research, I noticed that Hotlink no longer offers the 365 validity for new sim cards and was thinking of the Celcom XPAX one but have a few possible questions.

As I am planning to live overseas, I wouldn't be subscribing to the monthly plan but then use the Social (RM10 for 150MB data) until I travel. I was thinking of porting and then loading RM30 to extend the credit validity for 1 year and add a credit of RM100 (so that I can use the phone in case of emergencies.)

1) I presume that XPAX prepaid will allow me to use it while I am overseas (as they do offer IDD and International Roaming?
2) I presume that the RM100 credit that I reload will last for one year? (This is because I need to load of minimum of RM30 in 6 months right?) this is because I would be overseas and would be troublesome to reload it monthly.
A line from their terms: In addition to the above, the customer must reload a minimum of RM30 (e.g. Minimum of RM5 x 6 months) for a total cumulative period over 6 months from first subscription date of the Service.
3) The balance of data that I will be using can be carried forward for at least 1 year? (I may come back periodically and use some data).
4) Is there a better alternative (cheaper and better) then my current plan?

Thanks.
