No eSIM email within 2 minutes? Full refund.
The 2-minute delivery guarantee starts after payment is confirmed. If the eSIM email is not delivered within that window, we refund the order in full.
Unused eSIM
May be refundable if it has not been installed, activated or used and the profile can still be cancelled.

Service problem

Good to know
Vietnam FAQs.
Which networks can the plan use?
Current launch products include access through Viettel, Vinaphone and MobiFone partner networks. Actual network selection and available generation vary by location and device.
When should I install it?
Install before travel while you have reliable Wi-Fi, then follow the plan-specific activation instructions. Do not assume every plan starts at installation.
Does a Vietnam eSIM work on iPhone?
It can work on supported, carrier-unlocked iPhone models with eSIM capability. Device support varies by model and market, so check compatibility before purchase.
Can I keep my physical SIM installed?
Yes. On a compatible dual-SIM/eSIM phone, your usual SIM can remain installed while Roamvaya is used for travel data. Your home carrier’s own roaming settings and charges remain separate.
Can I use hotspot with the Vietnam eSIM?
Hotspot/tethering is generally supported on the current launch plans, subject to your device capability and settings.
Does the Vietnam eSIM include calls or a local phone number?
Roamvaya launch plans are data-first products unless a specific plan explicitly states otherwise. Internet calling and messaging apps can use the mobile data connection where those services are available.
Is 10GB enough for a Vietnam trip?
10GB is a practical fixed-data choice for many trips. Actual usage depends on video, hotspot, cloud backup and app behavior; shorter or longer trips may show different fixed-data options alongside the 2GB/day plan.
