How long does my eSIM data plan last?

Your eSIM plan lasts the validity period printed on the plan you bought. Usually 7, 15, or 30 days. The clock starts the moment your phone first connects to a partner network at your destination, not when you buy or install the eSIM. So you can install a 7-day plan a week before you fly without losing a day.

That one rule. Connection starts the clock. Answers most timing questions. The detail below covers the edge cases.

The clock starts on first connection abroad

Eflexsim plans don't run on a "buy date" or "install date." They run on a "first connection" date. The eSIM sits dormant on your phone until your device touches a partner cell tower in one of the countries your plan covers. The first successful connection starts the timer.

In practice: you can buy a plan today, install the eSIM at home on Wi-Fi tonight, and not lose any plan time until you actually land somewhere and your phone connects.

Two notes that matter:

• The timer is based on calendar days, not hours. A 7-day plan that starts at 3pm local time on Monday ends at 11:59pm local time the following Sunday.
• The timer doesn't pause if you stop using data. Once started, it runs continuously to the end of the validity window.

How validity is measured

Each plan has a fixed validity (7 days, 15 days, 30 days, etc.). Validity counts in calendar days from the moment of first connection.

A few examples:

• 7-day plan, first connect Monday at 10am: ends Sunday at 11:59pm local time.
• 15-day plan, first connect on the 1st: ends on the 15th at 11:59pm local time.
• 30-day plan: same rule. Counts 30 full calendar days from the day of first connection.

Local time means the time zone of the country you're connecting from. If you start in Italy and travel to Greece mid-plan, the end time stays anchored to wherever you were when the plan first connected.

What happens when your data runs out

Two limits matter on every plan: data amount (GB) and validity period (days). Whichever you hit first ends your plan.

• Run out of data, still in validity window: data stops. The eSIM still shows on your phone but won't connect. You can top up to extend without reinstalling.
• Validity expires, data still left: the eSIM stops working. Unused data doesn't roll over. The plan is closed.

There's no overage. Eflexsim doesn't charge extra if you exceed your data. It just stops working. This is intentional. No bill surprises after a trip.

Extending or replacing your plan

You have two options when a plan ends:

1. Top up the existing eSIM. Buy a top-up package and apply it to the same installed eSIM. No reinstall. See how to top up.
2. Buy a new plan. Install it as a second eSIM on your phone. You can keep the old one for record-keeping or delete it.

Top-up is usually faster. Same eSIM, more days, more data, no settings change. New plans are useful when you want to switch from a local plan to a regional one mid-trip, or if your destination changes.

A note on installing early

Because the timer starts on first connection, installing the eSIM early is the safest move. Install at home on Wi-Fi a day or two before you fly. The eSIM sits inactive until you land. No risk of losing time.

The only thing to avoid: turning Data Roaming on for the Eflexsim line while you're still at home. If your phone connects to a partner network somehow. For example, while passing through an airport with international cellular coverage. That would start the timer early. Keep the Eflexsim line toggled off in cellular settings until you've landed.
