How to Use the Travel WiFi Speed & Plan Cost Calculator
Picking a pocket WiFi or SIM plan by just grabbing the "fastest" option wastes money, while going too cheap often means buffering mid video call. This calculator figures out the actual minimum speed you need based on your connected devices and main usage, then rolls that up into a total rental cost for your trip.
Required speed is calculated by multiplying a per-device baseline by the number of connected devices. If you're mostly checking maps or messaging, 1 Mbps per device is plenty. Video calls need roughly 3 Mbps per device, and if several people are streaming HD video at once, budget 5 Mbps or more per device to avoid stutter.
It's easy to overlook that when a family or group all connects their phones to one shared pocket WiFi, the required speed multiplies fast. Three people on video calls at once isn't 3 Mbps — it's 9 Mbps or more. Enter your trip length and the daily rate automatically rolls up into a total rental cost, making it easier to compare plans.
Frequently Asked Questions
When multiple devices share a single pocket WiFi hotspot, they split the available bandwidth. Required speed is calculated by multiplying the per-device speed need by the number of connected devices — skip this and you'll likely hit buffering.
A typical video call runs smoothly at around 3 Mbps per device, but if multiple people are on calls at once or you're also streaming in high definition, aim for 5 Mbps or more per device.
