Data to plan for across 5 days at three levels of use, and which plan shape works out better at this trip length.
Quick answer
The figures below take three levels of daily use, multiply by the number of days, and add 15 percent for app updates and photo backup — the two things travellers forget.
| Level of use | Roughly per day | Total for 5 days |
|---|---|---|
| Бага хэрэглээ: газрын зураг, чат, имэйл | 0.4GB | 3GB |
| Дунд зэрэг: сошиал, зураг, богино видео | 0.9GB | 6GB |
| Heavy: streaming, video calls, hotspot | 1.9GB | 11GB |
At 5 days we would start with a mid-size fixed-GB plan, because that is where price per gigabyte and the risk of wasted data balance out. If your usage is uneven, weigh the top-up terms as well.
Multiplying days by daily use gets you close, but real trips are lumpy. Day one is usually the heaviest — navigating, checking in, messaging home — while a day on a tour or a long transfer can use almost nothing.
Most plans start counting at first connection to a network at the destination, not at payment — but some count from the purchase date. Check the activation-policy line on the plan page before buying weeks ahead.
Add at least one day. Delays, layovers and the trip home routinely spill past midnight, and a plan that expires while you are still at the airport leaves you offline exactly when you need it.
At 5 days the deciding factor is consistency. Even daily use suits a daily plan, which caps the cost predictably. Spiky use — heavy some days, nothing on others — suits a fixed-data pool.
