Just tried adding the digi sim card and key *128# but got error message.

“error performing request. Unknown error”

Yes, you can use the USSD code while in SG, I just used it and there's no charge. I normally start off with *128# and work my way from there; I don't normally use the shortcut/full-code in case they change the menu.

As for the end of the grace period to reactivate the card, I personally won't advice waiting until the last day. Do it at least 2 days earlier, especially if your SIM card is not in your phone all the time to receive SMS about an upcoming downtime in case of maintenance or whatever else.
