The honest daily numbers

Start from what apps actually consume. The activities that dominate a travel day, maps, messaging, browsing and social media, are remarkably light. The activities that burn data, streaming video and tethering a laptop, are the exception for most trips rather than the rule.

ActivityRough data useNotes
Maps and navigationVery lowAround 5 MB per hour of active navigation. Negligible over a trip.
Messaging (WhatsApp text)Very lowTiny, even with photos. Voice and video calls use more.
Social media browsingModerateRoughly 100 to 200 MB per hour, more if it autoplays video.
Music streamingModerateAbout 50 to 100 MB per hour at standard quality.
Video streamingHigh1 to 3 GB per hour depending on resolution. The single biggest consumer.
Video callsHighAround 0.5 to 1.5 GB per hour. Add up fast for remote workers.
Laptop tetheringVariableDepends entirely on the work. Can dwarf phone usage.
The rule of thumb

For normal travel use, plan on roughly 0.7 to 1 GB per day. That comfortably covers maps all day, constant messaging, regular social media and some music, with headroom. A Costa Rica trip often comes in under this, because the forests and remote lodges are offline, so you spend days using little or no data.

Data by trip type

Match yourself to the closest profile rather than guessing. These ranges assume you use lodge and hotel wifi for the heaviest tasks, like backing up photos or streaming at night, which is the normal pattern.

3 to 5 GB One to two weeks of nature and beaches with lodge wifi. Much of it spent offline.
5 to 10 GB Two to three weeks, or a more connected trip with daily posting and video calls.
10 to 20 GB A month of regular travel around the country without heavy daily tethering.
20 to 40 GB+ A working month: daily video calls, laptop tethering and uploads. Confirm tethering is allowed.

Profiles in detail

The nature-and-beach trip. Two weeks taking in Arenal, Monteverde, a Pacific beach and maybe the Osa Peninsula. Counterintuitively, this uses little data, because the cloud forest, the rainforest lodges and the remote beaches are largely offline, with wifi in the evenings. 3 to 5 GB is often plenty, concentrated in the towns and travel days.

The more connected explorer. Two to three weeks with more time in the towns and beach hubs, daily posting, and video calls home. 5 to 10 GB fits well, since you are connected more of the time.

The long backpacker route. A month moving around the country, heavy on maps and messaging for shuttles and bookings, lodge wifi at night, moderate social. 10 to 20 GB depending on how much you stream on mobile versus wifi. Top-up matters here because usage varies week to week.

The remote worker. Living and working from a beach town or San Jose for a month, with daily video calls, laptop tethering when the wifi is poor, and uploads. This is the only profile that genuinely needs 20 to 40 GB or more, and it is worth confirming the plan allows tethering and offers top-up.

The top-up strategy

The smartest approach for most travelers is to buy for the lower end of your estimate and top up once if you need more. Topping up takes seconds and costs less, in money and waste, than buying a large pack on day one and finishing with gigabytes unused. This is especially true in Costa Rica, where so much of the trip is spent off-grid anyway.

What inflates usage without you noticing

  • Autoplaying video in social feeds. Turn off autoplay on mobile data to cut social usage sharply.
  • Automatic cloud photo backup over mobile data. With all the wildlife and landscape photos you will take, set backup to wifi-only so a day's shots do not upload over your plan.
  • App and system updates. Restrict these to wifi so a large update does not consume a chunk of your plan.
  • Streaming on mobile out of habit. Save movies for lodge or hotel wifi in the evening.

Where we land

For most Costa Rica trips, 5 GB is the right zone, often with room to spare given how much time you spend off-grid, with top-up as the pressure valve. Buy toward the lower end of your honest estimate, keep heavy tasks on lodge wifi, and top up once if you run short. Only remote workers and heavy streamers should size up to 20 GB or more from the start. Our Costa Rica plans are sized across this range with top-up available, so you can start sensibly and add data only if your trip actually demands it.
