Depend where u going more?
Asia? Europe? SEA?

you can try esim from trip.com, i have tried few times cheap and reliable too.

My default has always been to purchase a local sim when traveling, but never at the airport because they charge tourist prices. Sometimes I go for esims, although convenient they are not that cheap. Has anybody tried sims from Gogo2roams or Hello1010?

Hotlink, but become expensive in recent year
for esim GlobalYo not too bad, affordable while stay connected, used quite few times during short stay in Taiwan, their regional place is cheaper than country specific plan so choose carefully.

AirAlo have signup offer for 300mb for 3 days

But recently not using anymore, fierce competition on Sg telco keep offering free big international roaming plans is rendering other esim plan effectively useless.
