Yes! With JamboSim's deferred activation, you can purchase your eSIM weeks or even months before your trip. Simply choose your preferred activation date during checkout - your data plan won't start until that day. This way you can prepare everything in advance and your eSIM will be ready the moment you land in Vietnam.
After purchasing your JamboSim eSIM, you'll receive a QR code via email. Simply scan it with your phone's camera, follow the on-screen prompts to install the eSIM profile, and enable data roaming. Your eSIM will automatically connect to the best local network when you arrive in Vietnam. The whole process takes under 2 minutes.
JamboSim partners with the leading mobile carriers in Vietnam to provide the best possible 4G/5G coverage across major cities, airports, and popular tourist destinations.
Yes! All JamboSim eSIM plans support hotspot/tethering. You can share your data connection with your laptop, tablet, or travel companions' devices while in Vietnam.
Your phone must be eSIM-compatible and carrier-unlocked. Most recent iPhones (XS and newer), Samsung Galaxy S20+, Google Pixel 3+, and many other modern smartphones support eSIM. If your phone is locked to a specific carrier, contact them to request an unlock before your trip.
Absolutely! Your JamboSim eSIM runs as a secondary line alongside your home SIM. You'll keep receiving calls and texts on your regular number while using JamboSim for affordable mobile data in Vietnam.
If you use all your data, you can instantly purchase a top-up plan through JamboSim - no need to visit a store. Your new data is available within seconds. You'll never be stuck without internet during your Vietnam trip.
A top-up lets you add more data to your existing eSIM without installing a new profile. If your plan supports top-ups, you simply purchase additional data through JamboSim and it's added to your current eSIM instantly - no new QR code needed. Not all plans support top-ups; you can check this in the plan details before you buy. If your plan doesn't support top-ups, you'll need to purchase and install a new eSIM when your data runs out.
