Tốc độ tải lên quan trọng hơn bạn nghĩ

Một số gói chuyển vùng giới hạn tốc độ tải lên thấp hơn tải xuống, nên các clip dài mất nhiều thời gian hơn dự kiến. Nếu bạn gửi file lớn hàng ngày, hãy dành thời gian và tận dụng Wi-Fi nơi lưu trú cho các việc nặng nhất.

Anyone shooting while they travel uses a connection in a completely different way from a holidaymaker. A tourist spends data pulling things down — maps, reviews, whatever they watch. A creator spends it pushing things up: full-resolution stills, finished cuts, and live video that streams for as long as the broadcast runs. The volume differs, and so does the shape.

This page is about sizing a plan against the work you actually have to deliver, and about the places people in this line of work misjudge it — nearly all of which sit on the upload side rather than the download side. We do not quote speeds as a promise, because real-world speed depends on the network in that country, where you are standing and when you are working. What we can give you is a way of thinking that keeps you from missing a delivery.

Why upload is the real bottleneck

Mobile networks are generally built around downloading, because that is what most people do. The consequence is that upload speed tends to trail download speed under the same conditions. For most travellers that is invisible. For someone shipping video every day it is the difference between finishing before bed and watching a progress bar until morning.

What makes it harder is that uploads dislike intermittent signal. A video you are watching stutters and carries on; an upload that drops halfway may have to start over, depending on the app or platform. That is why a spot with a steady signal beats a spot with a strong but patchy one.

Size it from the deliverables, not from the number of days

The estimate that works starts from the list of things you must deliver during the trip, not from the day count multiplied by a tourist average. Write down what has to go out, how many pieces, at what resolution, and how many of them will have to travel over mobile data. The number you get is usually well away from a rough guess.

Actual file size depends on resolution, the bitrate your camera or editor is set to, clip length and the codec. Those four can swing a file size several times over, which is why we do not publish a per-minute figure. A far more accurate method is to look at the real size of the last piece you delivered and multiply by how many you will ship this trip.

Work out the allowance your own workload needs

A live stream is not the same as uploading a file

An upload tolerates a slow connection as long as it eventually finishes. A live stream does not, because it has to push data out steadily for the whole broadcast. A dip in speed shows up immediately as stutter or a drop in quality, and a lost signal ends the stream then and there.

In practice that means always testing when you arrive somewhere new. A five-minute unlisted stream from the exact spot you intend to broadcast from tells you far more than the bars on the screen. Test at roughly the hour you will go live, too, because network conditions in a busy city differ a great deal between the middle of the day and the evening.

If the broadcast really cannot fail, keep a fallback: venue Wi-Fi you have actually tested, or recording locally and uploading afterwards instead of going live. The only fallback worth having is one you have tried.

Shrink the job before you ship it, rather than only buying more data

A lot of creators solve a data problem by buying a bigger plan when a small change in workflow would do more. Sending a low-resolution preview for approval and shipping the full file once you are back at the accommodation cuts volume substantially without touching the quality of the final delivery.

Another approach is to split the work into two piles: what must go out now because it has a deadline, and what can wait until you are back at the room or back home. Keep the first pile as small as the job allows and let the second one live on Wi-Fi where nothing is being counted. That is often enough to make a mid-sized plan sufficient.

Divide the work correctly between hotel Wi-Fi and the eSIM

The eSIM is for what has to happen while you are out: shipping small pieces, answering a client, finding a location, going live on site, and sharing to whatever other device is shooting. The accommodation Wi-Fi is for the heavy work that can wait: full-file uploads, backing up the day's footage, and pulling down large assets.

But do not assume the Wi-Fi will be good. Some places cap the number of devices, some crawl in the evening when every room is online at once, and some have a sign-in page that drops you periodically. If you have a real deadline, test the Wi-Fi the moment you check in rather than on the night the work is due.

Working across several devices at once

Shooting rarely involves one device. There is usually a phone as the hub, a laptop for editing, a tablet for references, and a camera that runs its own Wi-Fi to transfer files. Sharing the phone's connection out to those is normal enough, but there is a catch this line of work runs into more than most.

Battery matters just as much. Hotspotting while pushing a large file up makes a phone hot and drains it far faster than usual. If that is your whole day, carry a power bank that charges quickly, and do not leave the phone in direct sun while it uploads — an overheating handset throttles itself to cope.

What an unlimited plan actually means

Unlimited on a plan page means unlimited under the conditions that plan sets out, and those conditions are written differently from plan to plan. Some carry a fair-use clause; some describe a change in speed past a certain point. There is no universal figure we can quote, because none exists — read the detail on the plan you are about to buy.

For daily large uploads, consistency matters more than the word unlimited. A plan with a stated allowance that performs the same throughout may suit the work better than one labelled unlimited with conditions buried in the terms. Judge from what is written in the terms, not from the headline.

On a deadline day, work in this order

1. 1Check what is left before you startLook at the remaining allowance in the morning, not as you press send. If it is short of what the job needs, you still have a whole day to solve it rather than finding out at ten at night.
2. 2Ship the most important file firstWith several pieces to deliver, order them from the one that cannot slip to the one that can. If something goes wrong, what is left unsent is the least damaging thing.
3. 3Test with a small file before the big oneSend one small file to confirm the whole path works — the platform login and the speed you are getting — rather than discovering a problem halfway through a large one.
4. 4Find a spot with steady signal and stay putWalking around mid-upload makes the phone hand over between cells, a common cause of stalled transfers. Pick a seat and stay in it until it finishes.
5. 5Close anything competing for bandwidthTurn off automatic backups, app updates and cloud sync while a critical delivery is running. They work quietly in the background and use the same upward bandwidth.
6. 6Confirm with the other end that the file arrivedA completed progress bar does not mean the far end can open the file. Wait for confirmation, or check on the platform yourself, before you shut the laptop.

When an upload will not move, work through the usual causes

Shoots that cross several countries

If the job takes you through several countries in one trip, a single profile that works along the whole route removes a lot of places where things can go wrong. Travel days are already your busiest, and not having to install or switch anything on one is worth more than it sounds.

What to verify before buying is the actual covered-country list, including anywhere you only transit but still intend to work from. If a country is missing, plan the extra plan for that leg before you leave rather than solving it on the ground.

Look at regional plans for a multi-country shoot

Keeping the footage safe while you travel

This is not strictly a plan question, but it touches data use more than people expect, because a backup strategy built purely on the cloud will eat an allowance if it is not configured carefully. The first layer of any backup should need no internet at all.

• Copy cards to a portable drive every night, before thinking about the cloud
• Keep shot cards separate from the camera bag in case the bag goes missing
• Set cloud backup to run on Wi-Fi only
• Upload only the files that genuinely need an off-site copy
• Verify uploaded files open before formatting a card
• Keep contracts and job emails offline too, not just the video

Receipts and paperwork for freelance work

If the plan is a cost of the job, you will need paperwork for reimbursement or your accounts.
