Open your phone's data statistics and read the real figure before filling this in. Guesses are usually far off.
+2 GB
You are averaging 1.00GB a day, so the remaining 4 days need about 4.0GB.
Only plans marked as top-up capable can be extended. If yours cannot, buy another plan and install it as a second profile.
How top-ups workTop up before empty, not after
Topping up needs a connection. If you wait for zero with no Wi-Fi nearby you are stuck. Do it while about a day of usage remains.
Frequently asked questions
Does a top-up extend the validity?+
It depends on the plan: some add data only and keep the expiry, others extend the days. Each plan page states which.
What if my plan cannot be topped up?+
Buy another plan and install it as a second profile, then switch when the first runs out. Most phones hold several profiles.
Why is the daily rate high at the start?+
Day one usually includes app updates, map downloads and a lot of searching. The rate normally settles after that.
