Questions about Vietnam eSIMs
Does Grab work in Vietnam?
Everywhere in the cities.
It needs mobile data to book, to follow the driver and to pay, and the driver often messages you on the way.
Set the account up before you fly.
Will I have signal on a Halong Bay cruise?
Deep in the bay and inside the caves there is little or nothing, and most boats sell their own slow Wi-Fi.
Treat the trip as time offline rather than counting on a bar.
Tell people you will be out of contact.
Is there coverage on the Ha Giang loop?
Between the towns the passes have long dead stretches, and no plan promises what the towns themselves will do.
Download the route and your homestay bookings in Ha Giang city before you ride out.
Do I need Zalo in Vietnam?
It helps.
Homestays, drivers and tour operators use Zalo the way Australians use a text message, and some will only answer there.
It runs over mobile data like any other app.
Does data work on the train north from Hue?
On and off, with nothing at all through the hills and tunnels.
It is a beautiful ride, so download something before you board and watch the window instead.
Questions about every Ryvo plan
Will it work on my phone?
Does it come with a phone number?
No.
Ryvo eSIMs are data only.
There's no phone number, and you can't make calls or send texts on the eSIM itself.
Can I keep my usual number?
Yes.
Keep your main SIM on for calls and texts, and set the eSIM as your mobile data line.
Your carrier's roaming rates still apply to calls and texts, so check them before you go.
Can I share my data as a hotspot?
It depends on the plan.
Each plan says whether hotspot is allowed before you pay.
What if I run out of data?
Add data from your order page if your plan can be topped up.
If it can't, buy another plan for the same destination.
What if my eSIM won't connect?
Email us and we'll work through it with you, starting with your phone's mobile data settings.
If we can't get it working, our refund policy explains what happens next.
Before you go
Which of the three Vietnamese networks your plan uses is on the list on this page.
The Ha Giang loop, the hills around Sapa and the caves at Phong Nha are the gaps.
Grab, Be and Xanh SM all operate here, for cars and for motorbikes, and a bike crosses a city much quicker at five in the afternoon.
Zalo is the local chat app, and hotels and drivers often use it rather than WhatsApp.
Worth having before you need to find a homestay down an alley.
Keep your usual SIM switched on for calls and texts, and choose the eSIM for mobile data.

Email us your order reference, and we'll help you get connected.
