What Can You Do With 1GB of Data? Hours, Songs, Episodes

What can you do with 1GB of data on a trip? Roughly a hundred hours of turn-by-turn navigation, a full day of music, a few evenings of social scrolling, or twenty minutes of HD video. The spread between those answers is the whole point: a gigabyte is huge for some tasks and tiny for others, and knowing which is which tells you whether a 1 GB eSIM is a bargain or a trap. Every figure in this guide is calculated from a published rate, using 1,000 MB to the gigabyte, and each row of the table links to its source.

The direct answer: one gigabyte, task by task

The table below divides 1,000 MB by the per-hour or per-item cost of each activity in our usage data. Where the source gives a range, the table shows the range, with the shorter time first because the higher rate burns the gigabyte faster.

Activity	Rate from source	What 1 GB gets you	Source
Google Maps navigation	5–10 MB per hour	100–200 hours	Consumer Cellular
Spotify, Low quality	10.8 MB per hour (24 kbps)	about 93 hours	Spotify

Read down the right-hand column and the pattern is obvious. Anything that is text or a map lasts for days. Anything that is music lasts for a day or so of constant listening. Anything that is video lasts for an evening at best and for minutes at worst.

How each row was calculated

We want you to be able to check the arithmetic, so here is how the rates became hours. Our usage data states its conventions up front: all values are in decimal megabytes, 1 GB equals 1,000 MB, and a bitrate converts to data at kbps × 3600 ÷ 8 ÷ 1,000, which simplifies to kbps × 0.45 MB per hour.

Navigation

Consumer Cellular's planning guide lists GPS or map navigation at 5 to 10 MB per hour (Consumer Cellular). Dividing 1,000 MB by 10 gives 100 hours, and dividing by 5 gives 200 hours. Google itself does not publish a per-hour figure, so this is a carrier estimate rather than an app-maker one. Google does say that offline maps can guide you to your destination as long as the entire route is within the offline map, but that transit, bicycling and walking directions are unavailable offline (Google Maps Help). So a driver with a downloaded map spends nothing on navigation, while a walker in a new city spends a few megabytes an hour. Either way, maps will never be the reason a gigabyte runs out.

Music at each Spotify quality

Spotify publishes bitrates rather than megabytes: Low is approximately 24 kbps, Normal 96 kbps, High 160 kbps and Very high 320 kbps on Premium (Spotify). Multiplying each by 0.45 gives 10.8, 43.2, 72 and 144 MB per hour. One gigabyte is then 92.6 hours at Low, 23.1 hours at Normal, 13.9 hours at High and 6.9 hours at Very high. The Normal setting is the one most people are on without knowing it, and 23 hours of it is three full days of background music on a 1 GB plan. Switching to Very high quality cuts that to under seven hours, which is a single long travel day. Spotify's lossless tier has no stated bitrate on the page, so we do not compute a figure for it.

Netflix at each setting

Netflix gives per-hour ceilings for its account-level data setting: Low is up to 0.3 GB per hour, Medium up to 0.7 GB, and the High setting is up to 1 GB in standard definition, 3 GB in HD and 7 GB in 4K (Netflix). One gigabyte therefore lasts 3.3 hours at Low, 1.4 hours at Medium, exactly 1 hour at SD, 20 minutes at HD and about 8.5 minutes at 4K. The mobile app has its own settings and Netflix states them in hours per gigabyte directly: Save Data gives about 6 hours per GB, Automatic about 4 hours per GB, and Maximum Data can use 1 GB per 20 minutes or more (Netflix). Those convert to 167, 250 and at least 3,000 MB per hour. The practical takeaway is that a phone on Save Data stretches a gigabyte to six hours of viewing, while a laptop in HD empties it in twenty minutes. That eighteen-fold difference is the single biggest lever a traveller has.

Other video

AT&T's calculator methodology gives generic streaming figures that apply to services like YouTube: 11.7 MB per minute for standard definition, 41.7 MB per minute for HD and 97.5 MB per minute for 4K, which is 700, 2,500 and 5,850 MB per hour (AT&T). One gigabyte is 1.4 hours of SD, 24 minutes of HD and about 10 minutes of 4K. YouTube's own help page publishes no megabyte figures, only the note that higher picture quality uses more data, so the carrier estimate is what we have.

Video calls

Zoom's requirements for a 1:1 call are 600 kbps up and down for high-quality video and 1.2 Mbps each way for 720p (Zoom). Both directions count on a mobile plan, so the totals are 1,200 and 2,400 kbps, or 540 and 1,080 MB per hour. One gigabyte is 56 minutes at 720p or 1.85 hours at the lower setting. Google Meet's published needs are 1 Mbps out and 1.3 Mbps in for standard video, and up to 3.6 Mbps each way for 1080p (Google), which is 1,035 and 3,240 MB per hour. One gigabyte is 58 minutes at standard quality and about 19 minutes at 1080p. WhatsApp and FaceTime publish no figures, so our calculator assumes their calls fall in the same 540 to 3,240 MB per hour range. Audio-only is a different world: Zoom lists 60 to 80 kbps for VoIP audio, which is 27 to 72 MB per hour depending on whether that figure is one-way or both, so a gigabyte covers 14 to 37 hours of voice.

Browsing and email

AT&T puts web surfing at 250 KB per minute, or 15 MB per hour, and Consumer Cellular puts browsing websites or email at 60 MB per hour (AT&T, Consumer Cellular). A gigabyte is 67 hours at the low rate and 17 hours at the high rate. AT&T lists an email with no attachment at 20 KB and one with standard attachments at 300 KB (AT&T), which is 0.02 and 0.3 MB. A gigabyte is 50,000 plain emails or about 3,333 with attachments. Nobody on holiday sends that many, which is why email never shows up as a problem.

Photos

AT&T's figure for a photo upload to social media is 11.7 MB (AT&T). One gigabyte is about 85 uploads. Real sizes depend on the camera and the app's compression, but the order of magnitude is right: a dozen photos a day is a tenth of a gigabyte a week.

How fast a trip burns a gigabyte

A single activity rarely runs alone. The faster way to think about a gigabyte is as a daily budget, using the same calculator inputs our tool uses. Those inputs bundle the rates above into six habits: navigation at 5 to 10 MB per hour, phone video streaming at 250 to 2,500 MB per hour, social media at 120 to 700 MB per hour, video calls at 540 to 3,240 MB per hour, music at 43.2 to 144 MB per hour, web browsing at 15 to 60 MB per hour, and a daily allowance of 30 to 100 MB for messaging, email and background app refreshes.

A light day

Picture a sightseeing day: one hour of navigation, one hour of browsing for restaurants and tickets, one hour of music on the train, and the background allowance. At the low rates that is 5 + 15 + 43.2 + 30, which is about 93 MB. At the high rates it is 10 + 60 + 144 + 100, which is 314 MB. A gigabyte lasts between three and ten days of that. For a week-long trip where you keep video on hotel Wi-Fi, 1 GB is enough, and 2 GB is comfortable.

A typical day

Now add two hours of social media, the habit most people underestimate. Without video the social hours cost 240 MB, and with Reels or TikTok they cost up to 1,400 MB. The day becomes 333 MB at the low end and 1,714 MB at the high end. A gigabyte now lasts between fourteen hours and three days. This is the trip profile where a 1 GB plan runs out midweek and the traveller cannot work out why, because nothing they did felt like "using data".

A heavy day

Add one hour of phone video streaming and a thirty-minute video call home. At the low end that is 250 + 270, and at the high end 2,500 + 1,620. The day totals roughly 850 MB to 5.8 GB. A gigabyte lasts a day at best and three hours at worst. Anyone on this profile should be shopping for 10 to 20 GB or an unlimited plan, not asking what a single gigabyte can do.

What a gigabyte costs as a travel eSIM

If a light profile fits your trip, the smallest eSIM plans are cheap. Saily lists 1 GB valid for 7 days at $3.99 in Japan, Italy, France and Spain, $4.49 in the United Kingdom and Germany, $4.99 in Mexico and $5.29 in Canada (Saily Japan, Saily UK, Saily Mexico, Saily Canada). In the Dominican Republic, Nomad lists 1 GB for 7 days at $6 and Saily at $8.49 (Nomad, Saily). The step up is usually worth considering: Saily's 5 GB for 30 days is $10.99 in Japan (Saily), so five times the data costs under three times the price. Unlimited plans sit higher, such as Airalo's 7-day unlimited Japan plan at $26.50 (Airalo). For a US traveller comparing those with a carrier day pass, which is $12 a day on land with AT&T's International Day Pass (AT&T) and $12 a day in 210+ countries according to Verizon's TravelPass page (Verizon), the arithmetic usually favours the eSIM for anything beyond a long weekend. The per-country breakdown, including the cheapest price per gigabyte for each destination, is on our data by country pages.

Three ways to make a gigabyte last longer

The table shows where the big numbers are, and each one has a cheap fix. First, set Netflix's mobile app to Save Data, which Netflix says gives about 6 hours per GB instead of 4 on Automatic, and never watch in a laptop browser on mobile data (Netflix). Second, drop Spotify from Very high to Normal and a gigabyte of music grows from 7 hours to 23 hours. Third, download Google Maps offline areas for any driving so that navigation costs nothing, remembering that offline maps expire and must be updated before they do, and that some countries or regions do not allow offline downloads at all (Google Maps Help). Social video has no quality toggle worth mentioning in our sources, so the only fix there is to do less of it on cellular.

Run your own numbers

The daily profiles above are illustrations, and your trip will not match any of them exactly. Our trip data calculator takes the number of days and your hours per habit, applies these same sourced rates, and matches the total against the eSIM plans we track for your destination. It shows both the low and high estimates so you can see how much of the answer depends on whether your social feed is photos or video. If you are planning to share the connection with a laptop, read our hotspot data usage guide first, because a tethered laptop changes every figure in this table for the worse.

The short version

A gigabyte is a hundred hours of maps, a day of music, an evening of social video or twenty minutes of HD. Text, maps and audio barely dent it; anything with moving pictures drains it in an hour or less. On a light sightseeing profile 1 GB lasts most of a week, on a typical social-media profile it lasts a day or two, and on a streaming profile it is gone before dinner. Check the setting on your video apps before you fly, download your maps, and let the calculator tell you whether the $3.99 plan or the 10 GB plan is the right buy. So what can you do with 1GB of data? More than you might think, as long as you know which habits drain it.
