How Much Data Do You Need in the USA?
The short answer: for most travellers, 5GB to 10GB is usually enough for a standard holiday. Buying massive, expensive unlimited roaming bundles is often unnecessary—but running out of signal in New York, Orlando, or Las Vegas can quickly cause unneeded stress. Let's look at some real examples.

Do You Really Need Unlimited Data?
For the vast majority of UK tourists heading across the Atlantic, the honest answer is No. Paying a premium for an unlimited data package is usually bad math if you intend to spend most of your evening time on hotel or resort WiFi.
However, an Unlimited Data eSIM Plan becomes incredibly useful if you belong to any of these specific brackets:
- Heavy Hotspot / Tethering Users: If you need to share your mobile connection with your laptop for remote work, or hook up multiple family tablets in the back of a rental car.
- Constant Content Creators: If you stream video on the move or publish continuous, raw high-definition TikTok loops and vertical reels directly away from hotel rooms.
- Peace of Mind: If you simply do not want the cognitive load of checking your remaining data metrics during a once-in-a-lifetime family holiday.
The Apps That Use The Most Data
For most travellers, a 5GB or 10GB pool is more than enough if you follow standard routines. However, different digital activities put vastly different weights on your local connection pool:
mapGoogle Maps
Surprisingly lightweight. Highly efficient for basic turn-by-turn navigation, public transport routing, and finding nearby diners.
chatWhatsApp Texts
Standard text-based messages consume almost zero allowance. Routine text updates back home will barely move the needle.
photo_cameraInstagram Stories
High consumption. Auto-loading pictures, stories, and high-definition photo posts will eat your data much faster than standard websites.
smart_displayTikTok & Reels
Extremely high consumption. Constant streaming of vertical loop video content is the number one reason travellers unexpectedly run out of data.
movieYouTube / Netflix
Heavy drain. Streaming video in standard HD will burn through data pools rapidly. Save movie downloads for your hotel WiFi link.
videocamVideo Calling
Moderate-to-high drain. FaceTiming family or jumping onto WhatsApp video links will quickly increase your total consumption.
What happens if I run out of eSIM data?
This is the most common concern for first-time digital SIM users: "What do I do if I guess wrong and my connection drops in the middle of Orlando or Los Angeles?"
Don't panic. Unlike traditional physical SIMs, you don't need to visit a physical mobile retail shop. If you choose a 5GB plan and realise you need more data, you can simply purchase and add another prepaid eSIM online in less than two minutes via our main storefront link using any available local restaurant or airport public WiFi connection.

Is 5GB enough data for a holiday in the USA?
Yes. For most single-week holidays, 5GB is more than enough to handle day-to-day essentials like Google Maps, calling an Uber, checking flight details, and standard messaging.
Is 10GB enough for two weeks in the USA?
For the vast majority of tourists, yes. As long as you avoid heavy video streaming or endless TikTok scrolling while using your mobile data, 10GB will comfortably cover a standard two-week trip.
What uses the most mobile data when travelling?
Live video streaming (YouTube/Netflix), scrolling through video-heavy apps (TikTok/Instagram Reels), and background cloud photo backups are the fastest ways to drain your allowance.
Can I keep my UK number active while using a travel eSIM?
Yes, absolutely. Most modern smartphones allow you to keep your primary physical UK SIM active alongside your new digital travel eSIM line. You can receive important text messages and bank codes on your UK number while routing all internet data payloads through the affordable travel plan.
Choose The Right USA eSIM For Your Trip
Stop paying high daily network fees. Most travellers only need a simple 5GB or 10GB prepaid package to stay perfectly connected across America. Pick the plan that fits your schedule.
