Answers before you fly
The essentials for eSIM setup, compatibility, and refunds.
What is an eSIM?
An eSIM is a digital SIM built into your phone. Instead of swapping plastic cards, you install a data plan by scanning a QR code — no shops, no shipping, no paperclips.
How do I install my flowsus eSIM?
Buy a plan and we show you a QR code instantly. Scan it with your phone camera, tap "Add eSIM", and enable the line when you arrive. The whole thing takes about a minute.
Is my phone compatible?
Most phones since 2019 support eSIM — iPhone XR and newer, Samsung S20 and newer, Pixel 3 and newer. Dial *#06# and look for an EID number to confirm.
Can I keep my WhatsApp and iMessage number?
Yes. WhatsApp, iMessage, Telegram and friends keep working with your existing number — flowsus simply takes over the mobile data part.
What if it doesn’t work for me?
Plans are refundable within 30 days as long as they are unused and unexpired. Message us anytime — average first response is under 5 minutes.
