Support
Help before you fly, after you land, and everywhere in between. Reach a real person any time.
Installation and eSIM help
Get set up before departure so you can connect the moment you land.
How do I install my Korea eSIM
Open the QR code email we sent after purchase. On your device, go to Settings, then Cellular or Mobile Data, then Add eSIM, and scan the code. Keep your existing SIM in place if you want to keep using it alongside your Korea eSIM.
My device says it is not eSIM compatible
Most iPhone XS models and newer, Samsung Galaxy S20 and newer, and Google Pixel 3 and newer support eSIM. Your device also needs to be carrier unlocked. Check your device settings for an eSIM or Add Cellular Plan option to confirm.
Can I install my eSIM more than once
No. An eSIM QR code can only be installed once. If you delete the eSIM profile after installing it, you will need to contact support for a new QR code rather than scanning the original again.
How do I check my remaining data
Open My Trip to see your current data balance, or ask Korea Assistant at any time. Your balance updates in real time as you use data in Korea.
010 number help
Can my 010 number be used for banking or delivery apps
In many cases yes, but acceptance varies by provider. A temporary 010 number is not a replacement for long-term residency registration, and some banks and public institutions may not accept it for verification. Check with the specific service before relying on it.
What documents do I need to apply
You will need your passport information page, an alien registration card if applicable, and proof of arrival in Korea such as an entry stamp or boarding pass.
How long does activation take
Most applications are reviewed and activated within the same day once your documents are submitted. You will receive a notification when your number is ready to use.
Insurance help
Does Mobiluma sell travel insurance directly
No. Mobiluma is not an insurer. We help you compare options and connect you to an authorised insurance partner, who issues and manages your policy.
How do I file a claim
Claims are handled by your insurance partner. Open My Trip and select File a Claim to be directed to the correct process for your policy, or contact your partner directly using the details in your policy documents.
