What our users say
Users highly praise and recognize eSIM.CC
Keep my physical SIM for calls and run data on the eSIM—support even sent step-by-step screenshots so I wouldn’t mess it up. Rock-solid, easy to budget, and a time-saver. Perfect for frequent short business trips.
Did Singapore–Malaysia–Thailand back-to-back with zero SIM-card counters. Land in a new country and it just works. The usage dashboard stops you from burning all your data on videos on day one. Super convenient.
Cheaper than my carrier’s roaming, and you only pay for the days you need—no waste. I asked about switching plans and support replied fast. When traveling, I just want no stress and no dropouts—this nailed it.
I installed the eSIM in advance, and the moment the plane stopped, I had signal. Maps, rides, streaming—all smooth. Plus I could share hotspot with my travel buddy.

Frequently Asked Questions
Find quick answers to the most common questions about eSIM.
What is an eSIM?
An eSIM (embedded SIM) is a virtual SIM built into your device—no physical card or tray required. It lets your device get online, make and receive calls, and send texts.
Do I need to enable Data Roaming on my device?
Yes. For the best coverage, please turn on Data Roaming in your device settings. This action itself does not create extra charges.
Does eSIM.CC throttle speeds?
If you purchase a standard data package, speeds are generally not throttled unless a plan explicitly states otherwise.
When does my eSIM plan start counting time?
Time does not start immediately at activation. It begins when you arrive at your destination and the eSIM first connects to a local network.
I ran out of data. Can I top up?
Yes. Log in to your eSIM.CC account on the website to add data or purchase a new package.
My phone doesn’t support eSIM. Can I still use eSIM.CC?
Usually not, but you can use an adapter (such as a 9esim-style card) to add eSIM support to certain compatible devices.
Can I keep my WhatsApp number?
Yes. Your existing WhatsApp number, chats, and contacts remain unchanged and are not affected.
Can I get a refund for my eSIM?
If your eSIM has not been used, you can request a refund within 90 days of purchase.
