Plan validity & expiration

Understand when your plan starts, how long it lasts, and what happens when it expires.

Plan validity & expiration

Every Simsima plan has a data allowance and a validity period. Here is how they work.

When does my plan start?

Your plan validity period begins when the eSIM first connects to a local network at your destination. This means:

Installing the eSIM does not start the clock

Install it before you leave, on Wi-Fi: it activates when you arrive and connect to a local network

You can install days or weeks before your trip without losing any validity

Regional and Global plans: if you are already in a country the plan covers, it activates as soon as it connects

How long does it last?

Plans come in various validity periods:

7 days — Short trips and weekends

15 days — Two-week vacations

30 days — Extended stays and business trips

Custom periods — Some plans offer different durations

The validity is clearly shown on the plan page before purchase.

What happens when my plan expires?

When either the data runs out or the validity period ends (whichever comes first):

Your eSIM will no longer provide data

The eSIM profile remains on your device (you do not need to delete it)

You can top up if the option is available, or purchase a new plan

Can I pause my plan?

No, once the validity period starts (first network connection), it cannot be paused. The countdown continues even if you turn off the eSIM line.

Unused data

Data does not roll over to a new period. If your 10 GB plan has 3 GB remaining when the validity expires, that data is lost. Choose your plan size based on your expected usage.

Unlimited plans

Some destinations offer unlimited data plans. With these plans:

You get unlimited data for the entire validity period

After your daily high-speed allowance, speed is reduced until the next day; the exact allowance is shown on each plan

The plan expires only when the validity period ends

Unlimited plans are ideal for heavy users, hotspot sharing, or trips where you do not want to monitor your usage.

Planning tips

Estimate your usage — Use our Data Usage Calculator for a personalized estimate. As a rule of thumb, 1 GB covers roughly 3-4 hours of browsing or 30 minutes of HD video

Buy slightly more than you think — It is better to have leftover data than to run out mid-trip

Consider top-ups — If unsure, start with a smaller plan and top up if needed

Try unlimited — For peace of mind, consider an unlimited plan if available for your destination
