What Is Mobile Data Usage?
Mobile data usage is the traffic you use over the cellular network when not on Wi-Fi — every time you scroll Instagram, look up directions on Google Maps, or video call home, it counts against your data. You usually won't have Wi-Fi everywhere while travelling, so estimating beforehand and buying the right amount avoids running out mid-trip or overpaying for data you won't use.
How We Calculate It
Roughly how much data each type of activity uses per hour (industry-standard estimates):
Os valores por hora acima não foram medidos no seu telemóvel — foram convertidos a partir de tamanhos de ficheiro típicos. A mesma aplicação pode consumir quantidades muito diferentes consoante a qualidade e a atualização em segundo plano, por isso considere o resultado uma ordem de grandeza, não uma previsão de fatura. Para perceber por que o mesmo consumo existe em planos de “quota diária” e de “dados totais” — e qual lhe convém — ver Daily quota vs. total data。
These figures are estimated from typical file sizes — actual usage varies noticeably by app settings, video quality and background refresh. Treat them as order-of-magnitude guidance. The single most effective way to save data: download offline maps before you leave, and turn off autoplay in social apps.
