Frequently Asked Questions
Is eSIM data speed slower than a local SIM card?▾
No. Travel eSIM connects to the same carrier networks (e.g., NTT Docomo in Japan, Vodafone in Europe) at the same speeds. There is zero technical difference in data speed between eSIM and physical SIM.
Can I keep my home phone number while using eSIM abroad?▾
Yes! That's one of the biggest advantages. Your eSIM runs as a second line alongside your home SIM. You receive calls and texts on your regular number while using the eSIM for data.
What happens if I run out of eSIM data during my trip?▾
You can instantly purchase a new eSIM plan through MyeSIM at any time. The new plan activates in under 2 minutes — no need to find a store or go without internet.
Do I need to unlock my phone to use a travel eSIM?▾
If your phone is carrier-locked (purchased through a carrier payment plan), you may need to request an unlock first. Most phones purchased at full price or directly from the manufacturer are already unlocked.
Which devices support eSIM?▾
Most modern smartphones support eSIM: iPhone XS and later, Samsung Galaxy S20 and later, Google Pixel 3 and later, and many other flagships. Check our compatible devices guide for the full list.
