Check the activation and validity terms for the exact plan before buying or installing it. Installation, network activation and the start of paid validity are related but are not always the same event.
What to check
- What starts the validity period: installation, activation or another event specified by the plan.
- Whether there is a deadline to install or activate after purchase.
- The duration and any end date shown for the plan.
- The countries covered, including places you will transit through.
Do not assume every plan can wait a year, starts only at your final destination or measures a day in the same way. Ask support to check your plan if those details are unclear.
After activation
A validity period generally keeps running while the line is turned off or you are using Wi-Fi. Turning off mobile data does not pause a plan.
Top-ups
Check the exact top-up's validity and replacement terms. Do not assume unused data rolls over or that buying more data extends the original expiry. See "Top up a plan that has run out".
