How to Check If eSIM Is Using Data

Q: Where can I check data usage in my NoveSIM account?

Log in, go to Orders, open the relevant eSIM order, click View, then select Check Data Usage.

If you have both a primary SIM and an eSIM active, it is important to confirm which line is actually using mobile data.

Many travelers install an eSIM successfully but continue using their home SIM for data without realizing it.

Quick answer: Check your phone settings and make sure the eSIM is selected as the Mobile Data line. You can also verify usage in your NoveSIM account → Orders → View → Check Data Usage.

Important: Using the wrong data line may result in home carrier roaming charges. Usage depends on device settings and our General Conditions.

Why This Matters

If your home SIM remains the active data line, you may:

Use expensive roaming by mistake
Think the eSIM is not working
Consume your main carrier data
Miss the benefits of your travel eSIM

Signs Your eSIM Is Using Data

Internet works while eSIM is selected
4G / LTE / 5G appears on the eSIM line
Your main SIM roaming can stay off
Usage counters increase on the eSIM line
Your NoveSIM account shows usage under Orders → View → Check Data Usage

Extra Ways to Confirm

1. Turn Off Main SIM Data

If internet still works, your eSIM is likely handling data.

2. Check Data Usage Stats

Many phones show data used by each SIM line.

3. Disable Wi-Fi Temporarily

This confirms you are testing mobile data, not Wi-Fi.

Tip: Turn Wi-Fi off briefly when testing so you know mobile data is being used.

Check Data Usage in Your NoveSIM Account

You can also check your eSIM usage directly from your NoveSIM account dashboard.

Log in to your NoveSIM account
Open Orders
Find the relevant eSIM purchase
Click View
Select Check Data Usage

This allows you to confirm whether data has been used and helps verify that the purchased eSIM plan is active.

Tip: If your phone shows internet but you are unsure which SIM is being used, checking usage in your NoveSIM account is one of the easiest ways to confirm activity.

What If Internet Does Not Work?

The eSIM may be selected, but another setting may need attention.

Data roaming OFF
APN settings issue
Weak signal
Plan not active yet

Why This Matters for Travelers
