If you went oversea for less than m 3 months at a time then yes, since you need to make a call/text or consume data every 3 months to keep it alive

I'm not sure if anybody tested the sms function while oversea, you might extend the validity this way

If you stay overseas longer than 3 months the safe bet is xox, make sure you have enough validity before going abroad, you can even purchase several or even tens of years validity in advance and the only other known telco that allows this is hotlink, unlike other telcos where you need to wait until validity expires only then you can purchase new validity

Instead of reloading rm100 in lump sum you can reload rm10 every 2.5 months to be safe and you will get 2+ years, no sms necessary

But need to remind you the credit is not transferable so you should take that into planning

You should contact Unifi CS for clarification on whether international text is enabled and is counted for extending validity

The thing I don't like about Unifi is there is no clear date on when your sim will be deactivated, lost several Sims because I forgot to use them

if you stay abroad most of the time, then use your foreign number to receive TAC.

most banks can send to overseas number with the exception of *tiger* bank.

Lol, too bad. I avoid that tiger...and my tac is sent to overseas number which is very easy to keep alive.

Cheap data. When come back then buy sim card from convenience store. Use and throw.

There have been reports that unifi doesn’t roam well. So good luck.
