Which day does this plan expire
Validity starts at first connection, not at purchase.
Last updated September 4, 2026
The commonest misunderstanding is that the clock starts at checkout, which stops people buying early. On most plans it starts when the phone first registers at the destination.
Pick a date
The plan expires at the end of that day in destination time. Any unused data goes with it — nothing rolls over.
Details that cost you the last day
- Expiry follows destination time, not your home clock
- If the return flight is late on the final day, add a day
- Leftover data expires with the plan; nothing carries over
Frequently asked questions
Can I buy weeks ahead?+
Yes for plans that start on first connection, which is the common case — but check the activation policy row in the spec table each time.
I activated it early by mistake+
Once the clock starts it usually cannot be reversed. Contact us with your order number and we will tell you plainly what can be done.
Does installing the profile count as activating?+
Installing is not activating. The clock starts when that line actually connects at the destination, so installing at home is safe.
