Not necessarily, since it depends on the local network and actual conditions in that area at the time, which differ from the network you are used to at home.

There can be a small discrepancy between the figure the device counts itself and the figure on the orders page, since the two do not count in exactly the same way — treat the orders page figure as the primary reference.

Network speed changes constantly with the number of users and conditions at that moment, so a speed-test app result only captures a brief snapshot, not a constant value.

Generally a big city tends to have denser network coverage than a rural area, though this is not an absolute rule — it depends on the actual local network operator in that specific area.

It depends on that plan's own terms — some plans return to normal speed immediately after topping up, others may work differently. Check the plan's page or the top-up category for clarity.

Yes, it does, since the data volume bought is one shared pool used across the whole plan period, not automatically divided into a daily allowance. Planning roughly ahead of time helps if you want it to last the whole trip.

Yes, it is — the number of other users sharing the same network changes by time of day, so a measured speed can genuinely differ without anything being wrong.

It can help a good deal for anyone taking photos often during a trip, since each high-quality photo adds to upload data quickly. Turning it off temporarily and syncing all at once over Wi-Fi noticeably cuts mobile data use.

Because a large number of people are sharing the same network in the same spot at once, temporarily lowering the average speed per person — normal behaviour in any densely crowded area.
