How I'd sort money and data before a regional trip
By Marcus Tan·
Singaporeans take a lot of short regional trips — a weekend in Bangkok, a few days in Bali, a JB run that turns into KL. The connectivity-and-money prep is basically the same every time, so it is worth having a routine rather than scrambling at the airport. Here is the order I would do it in.
A week before: pick the eSIM
Decide where you are going and roughly how much data you will use, then choose an eSIM. For a short trip a small plan is plenty. Buy it and install it now, while you are on home Wi-Fi — it sits dormant until you switch it on overseas.
The same evening: sort the card
If you do not already have a multi-currency card, this is the moment. Decide what matters to you — simplicity, keeping your miles, or staying inside your existing bank — and set one up. If you do have one, just top it up with the currency you will need so you are not converting at a bad weekend rate later.
Two days before: the small checks
Confirm your phone supports the eSIM and that it is installed. Check whether any credit card you hold already includes airport lounge access — many do, and people forget. Download offline maps for your destination as a fallback.
The night before: switch-on plan
Know what you will do on landing: turn telco roaming off, switch the eSIM line on, and keep your physical SIM in for any OTP messages on your Singapore number. That is the whole routine. Done once deliberately, it becomes muscle memory for every trip after.
