Is 1 GB per day enough for a normal trip?

Yes for most travellers. Maps, messaging, ride-hailing, browsing, and a moderate amount of social media fit comfortably inside 1 GB per day. It is not enough if you stream video or work from a tethered laptop.

Does Google Maps use a lot of data?

No. Turn-by-turn navigation consumes only a few megabytes per hour because the map tiles are cached and only your position updates. Downloading an offline map area reduces it further.

Can I top up if I run out mid-trip?

Yes. You can buy an additional plan for the same destination and switch to it, so running low is an inconvenience rather than a trip-ending problem. Sizing correctly up front is still cheaper.

Do unused gigabytes roll over to my next trip?

No. Travel plans expire at the end of their validity period and unused data is lost. Choose the size that matches the trip rather than buying a large buffer you will not use.

How many gigs of data do I need for a trip?

Short answer

For a typical trip, budget around 500 MB to 1 GB per day. That means roughly 3-5 GB for a week of maps, messaging, and light browsing, 7-10 GB if you post to social media daily, and 15-20 GB or unlimited if you stream video or tether a laptop.

Check it yourself before you buy: iPhone Settings > Cellular > Current Period, or Android Settings > Network & internet > Data usage, shows your real daily average. Travel usage is normally lower than home usage, because hotel and cafe Wi-Fi covers a large part of the day.

What each activity actually uses

Google Maps navigation — roughly 5 MB per hour of driving. Maps is far cheaper than people expect.
WhatsApp and iMessage text — under 10 MB per day for heavy chatting.
Instagram or TikTok scrolling — 100-200 MB per 10 minutes on autoplay video. This is what drains plans.
A one-minute Instagram Story or Reel upload — 10-30 MB.
Web browsing and email — 20-50 MB per hour.
Music streaming — around 70 MB per hour at standard quality.
Netflix or YouTube — 700 MB to 3 GB per hour depending on resolution.
A video call — 200-400 MB per hour.

Trip-length cheat sheet

Weekend, 3 days, light use: 1-3 GB.
One week, maps and messaging, occasional photos: 3-5 GB.
One week, daily social posting: 7-10 GB.
Two weeks, normal use: 10-15 GB.
Any length with laptop tethering or video streaming: 20 GB or an unlimited plan.
Digital nomad working remotely: unlimited, and confirm hotspot is allowed.

Total plans versus daily plans

A Total plan gives you one pooled allowance for the whole trip, so a heavy day balances out a quiet one. A Daily plan resets every 24 hours, which suits long stays with steady usage but wastes anything unused each day. For trips under two weeks, a Total plan is usually the better value.

Four settings that halve your usage

Download offline maps for your destination before you fly.
Turn off autoplay video in Instagram, TikTok, and X while on cellular.
Set iCloud Photos and Google Photos backup to Wi-Fi only.
Download playlists, podcasts, and episodes on hotel Wi-Fi the night before.
