A plan's clock, from buying it to the day it startsThree marks on one line. Buy and Install both show a stopped clock, because buying and installing do not start a plan on their own. First connect is ringed, the clock starts running and the plan's first day begins there, and the plan runs for the days it lists from that point. Depending on the plan it starts when you install the eSIM, when it first connects at your destination, or when you buy it. If you're not sure when yours starts, email us before you install.BuyClock stoppedInstallStill stoppedFirst connectDay 1
Most plans start on first connection. Your plan page says.

How it works

  • The phone checker, with a model typed in and a yes backThis site's own phone checker, drawn. A phone model is typed into the Phone model field, and under the Check my phone button the answer says the phone supports eSIM, ticked and marked Supports eSIM. The checker answers from one list of phones, checked against each manufacturer's own page, and it never guesses: a phone that is not on the list gets told so. Your phone also needs to be unlocked.Phone modeliPhone 15 ProCheck my phoneSupports eSIMYes, the iPhone 15 Prosupports eSIM.

  • The Mobile data screen at home, with the new line listed and roaming offA phone's Mobile data screen with two lines on it. Main, your home carrier, is still ticked for mobile data. The new line, labelled Travel, is the Ryvo eSIM, newly listed under it. Data roaming is off, so nothing has connected and the plan's clock is stopped. Beside the phone, a Wi-Fi symbol: install over Wi-Fi or your home data, any time after you buy, and give the line a label like Travel so you can tell your lines apart.9:41Mobile dataMainHome carrierTravelRyvo eSIMData roamingOFFAt homeNot started

Travel, the Ryvo eSIM, is now ticked for mobile data, and Data roaming is on for it. Beside the phone, signal bars and a running clock: the eSIM has connected to a partner network, and on a plan that starts on first connection that is where its first day begins. Your own plan page says when yours starts.9:41Mobile dataMainHome carrierTravelRyvo eSIMData roamingONConnectedDay 1

Do I need an eSIM in Vietnam?

Yes, and you will want it from the airport.

Grab is how most people get anywhere in Hanoi or Ho Chi Minh City, and it needs data to book.

Viettel, Vinaphone and Mobifone are the Vietnamese networks, with the gaps in the far north mountains and out on the water.

Local plan or World eSIM?

Questions about Vietnam eSIMs

  • Does Grab work in Vietnam?

    Everywhere in the cities.

  • 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.

  • 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.

  • Do I need Zalo in Vietnam?

    It helps.
