With growing affluence, more and more Singaporeans are travelling overseas, be it for work or holiday, at least once per year, and with the widespread fandom of K-pop and K-drama, South Korea is one of the top destinations.
However, what local SIM card is the best for you to use to roam in South Korea? After all, there are so many things to be posted on Instagram, so many places to search for with Google Maps or Naver Maps, and so many translations needed with Google Translate.
Take your pick below!

As seen above, the best Postpaid plan to be on for South Korea travellers would be M1’s $25 for 30GB SIM-only plan. With an addition of a $25 Data Passport, users would be able to use their entire data bundle in South Korea as well (after all, your 30GB won’t be used in Singapore while you’re in Korea, so might as well use it there), driving the per GB roaming price to $1.67.
However, the rates offered by GOMO and giga! are also attractive, an average of $5 per GB. However, the validity for giga! may not be attractive as hardly anyone travels to South Korea for just 5 days, so users would have to purchase its gigaRoam APAC twice for 2GB for $10 (10 days).
If you’re on other Postpaid providers other than M1, GOMO or giga!, fret not. You can simply purchase a StarHub Prepaid Happy SIM and purchase the $25 WOW Data Plan. It comes with 20GB (16GB for local data only, 4GB for local and roaming – with South Korea being one of the destinations). While the upfront price is $25, you do get 4GB for roaming, driving the per GB price down to $6.75. What’s more, you also get 16GB back for use in Singapore as well as free 10GB every Sunday. The validity for the 4GB is also sufficient at 30 days, making it a strong roaming proposition.
Overall, the following are the recommended options as discussed above.
| Provider | Type | Product | Data & Price | Validity | Price/GB | Other Benefits |
| M1 | Postpaid | $25 Data Passport | N.A. | Monthly | $1.67 | Unused data can be used in SG. |
| GOMO | Postpaid | Roaming Data Pump | 2GB for $10 | 10 days | $5 | N.A. |
| giga! | Postpaid | gigaRoam APAC | 1GB for $5 | 5 days | $5 | N.A. |
| StarHub | Prepaid | WOW Data Plan | 4GB for $25 | 30 days | $6.75 | Unused data can be used in SG. 16GB more in SG. free 10GB in SG every Sunday. |
