eSIM is short for embedded SIM - basically, it’s a digital SIM card. Where physical SIM cards previously were necessary for telcos to authenticate a subscriber’s identity, the eSIM now puts that hurdle to rest. What does this mean for you?

You won't need to swap SIM cards to a local network while overseas!

This has great value for almost everyone. But especially for business or frequent travelers, who will enjoy a ton of added convenience by being able to roam freely between countries!

So while your current SIM-only unlimited data plans may be great value for money, the playing field is about to change.

That is why OYA will use eSIM for its new service, which aims to provide hassle-free data to users all over Asia.

So can I get eSIM now?

eSIMs are actually already here! When OYA launched in in 2019, it became the first 100% eSIM, data-only service in Singapore.  So if you want to be one of the first in the city to use an eSIM on your device, you can go ahead and sign up here.

Is eSIM hard to set up?

We’ve made it as easy as possible to get online with your OYA eSIM on the latest iPhones. In fact, it’s even easier than a physical SIM.

Step 1. Download the OYA app from the AppStore here.

Step 2. Verify your ID. OYA does this in the app — just snap your IC and a picture of your face, and you’re ready to go.

Step 3. Activate your eSIM directly in the app.

Step 4. Buy your data! Go on an Instagram stories binge, or start streaming some Netflix in 4K. The best thing is, OYA data never expires. Come back in six months or a year, and it’ll still be there waiting to be used.

Is eSIM better than a dual-sim phone?

If you own a dual SIM phone, you’ll probably know it allows you to have two active SIM cards running in tandem.

eSIM phones (including the latest iPhones) work the same way: they're developed to support a physical SIM and an eSIM. You’ve then the option of selecting one as your primary service. This service will be used to make calls and texts by default.

With your second SIM (eSIM), using a telco like OYA will allow you to load up on cheap data that never expires, so you can always be connected for WhatsApp calls and messages, plus stream Spotify or YouTube videos without worrying about busting your data limit (and being charged excess usage fees).

Even if you’re on an unlimited data plan, many telcos in Singapore often include a cap on data usage, after which you can expect throttled (aka slower!) internet speeds.
