Quantroam is a smart global connectivity service that gives travellers an e-Sim they can use anywhere in the world.
No physical SIM cards and no roaming fees — just simple, reliable data wherever you go.
Quantroam replaces expensive roaming with transparent, travel-friendly data plans. Instead of paying your home carrier’s high roaming rates, you connect through local partner networks at fair, prepaid prices.
You only pay for the data you choose — no hidden fees, no surprise bills when you return home.
- No. With Quantroam, you don’t need to buy physical SIM cards for each country you visit.
- Once you choose the data plan you want, we’ll email the e-Sim QR code directly to your inbox.
- Simply scan it on your device to activate the plan — no SIM swapping required.
If you accidentally delete your Quantroam e-Sim, don’t worry. Simply contact our support team, and we’ll reissue a new e-Sim profile for your device.
