Common Questions
How much does a Asia eSIM cost?
SimSwift Asia unlimited daily plans start at $5.99 a day.
When does the Asia eSIM activate?
It activates when you connect to a supported network in Asia (usually upon arrival). No manual activation needed—just land, turn on your phone, and you're connected. In Asia, this could be in Bangkok, Singapore, or Tokyo—popular destinations where connectivity matters.
How does an eSIM work?
An eSIM is a digital SIM built into your phone that activates mobile data without a physical card. After purchase, you install the Asia eSIM in one tap from your order email. Once you arrive in Asia, your phone connects to local networks automatically—no SIM swaps or roaming fees.
How do I install Asia eSIM on iPhone?
Open your order email on your iPhone and tap the install button: the eSIM installs in one tap, then follow the prompts. Once installed, select the eSIM as your data line. You’ll need to enable Data Roaming on the eSIM line (not your primary SIM) to connect in Asia.
How do I install Asia eSIM on Android?
Open your order email on your Samsung, Pixel or other eSIM phone and tap the install button: the eSIM installs in one tap. Set the eSIM as your data line and enable Data Roaming on the eSIM profile to use mobile data in Asia.
Can I install my Asia eSIM before travel?
Yes! Install anytime before your trip—it won't activate until you arrive in Asia and connect to a local network. You have 180 days from purchase to activate.
Do I need to turn on Data Roaming for Asia eSIM?
Yes, enable Data Roaming on the eSIM line (not your primary SIM). This allows the eSIM to connect to local networks in Asia. You won't be charged roaming fees—it connects as a local plan with no extra charges from your home carrier.
Does Asia eSIM support hotspot/tethering?

Will WhatsApp work with a data-only eSIM?
Yes! WhatsApp and iMessage stay linked to your home number. The Asia eSIM is data-only, so your existing messaging apps work perfectly—you keep all your chats and contacts.
Can I make calls with a data-only eSIM?

Your eSIM connects to premium local networks including Telkomsel, KDDI, Metfone, SKTelecom, LG U+, DiGi, Maxis, Celcom with 3G/4G coverage. Whether you're in Bangkok, Bali, or Mumbai, you get the same service as locals, with automatic switching between carriers for the best signal.
Is Asia eSIM better than buying a local SIM?
Yes—no airport queues, passport checks, or language barriers. Install your Asia eSIM before you travel, saving time on busy at airports or border crossings, and connect instantly whether you're visiting iconic sites like the Great Wall or exploring bustling city markets.
