Using mobile data while traveling should be simple. If you are using an iPhone with an eSIM, it is important to keep track of your data usage. This guide shows how to check your data directly on your iPhone and manage your settings to avoid running out while still linking you to helpful tools like the eSImo app, device compatibility page, and iPhone eSIM plans.

Step 1: Make Sure Your iPhone Works with eSIM

Before you start tracking data, confirm your iPhone is eSIM-compatible.

• Check here → Device Compatibility
• If compatible, activate your plan here → iPhone eSIM Page

Step 2: How to Check Data Usage on iPhone

You can see exactly how much data you have used and which apps are using it by following these steps

1. Open Settings and tap Cellular or Mobile Data
2. Look under Current Period to see total data used
3. Tap Reset Statistics at the start of a new trip or billing cycle
4. Scroll down to view data usage by app
5. Tap Cellular Data Options then Data Mode to enable Low Data Mode for better control

Step 3: Save Mobile Data with iPhone Settings

Your iPhone includes several tools to help reduce data use

• Low Data Mode reduces background data activity
• Turn off Background App Refresh for apps that use data in the background
• Disable Cellular Data for apps you do not need while on the go
• Turn off Wi-Fi Assist to prevent the phone from switching to data when Wi-Fi is weak

Step 4: Prepare for Your Trip

Here are simple tips to manage your data while traveling

• Reset your statistics before your flight or train
• Use Wi-Fi for downloads, video calls, and map updates
• Check your data frequently in the Cellular section of Settings
• Bookmark eSImo’s app for easy top-ups and plan info if needed

You do not need extra apps to check your iPhone data. Everything you need is in your phone settings. If you need an eSIM plan that fits your device, check out device compatibility and activate a plan from the iPhone eSIM page.

You can also use the eSImo iOS app if you want an easy way to manage your eSIM data and top up when needed.

Stay connected and in control wherever you go.
