Are you planning a trip to the US? We know that staying connected is an essential part of your journey. There are several options, including Wi-Fi, eSIMS, portable routers, SIM cards and data roaming.
Today, we are going to clarify everything about data roaming, so you can decide if it’s the best alternative for you.

What is Data Roaming?
Let’s begin with the basics: What is data roaming? It is a service provided by your home carrier that allows you to connect internationally. This means your local carrier gives you access to foreign networks in the country you’re visiting. Depending on your cellphone plan, this can include sending SMS, making calls, and using an internet connection.
Before we continue, it is important to consider the advantages and disadvantages of choosing data roaming as an option.
Advantages:
- You don’t have to worry about purchasing a new SIM card or finding a local Wi-Fi network. It’s all integrated into your existing plan, offering a convenient experience
- You can choose a plan with your local carriers that adapts to your needs. This allows flexibility based on your travel requirements.
Disadvantages:
- Data roaming can be expensive, so it is important to be aware of your data consumption to avoid any unexpected charges.
- Remember that not all countries offer data roaming services, and coverage can be limited.
- Your connection speed might be slow in comparison to what you are used to at home.
Buying an eSIM for USA: The best option to avoid roaming charges
Looking for an eSIM with unlimited data is the best option to stop paying roaming fees. An eSIM is a virtual chip that connects to the best networks in the United States.
Below we show you how to activate an eSIM for the USA.

1. Check eSIM compatibility
Ensure that your phone is eSIM compatible. Most recent iPhones, Android devices, and some other smartphones support eSIM technology. You can check your device’s compatibility on the manufacturer’s website or consult the manual.
2. Obtain your eSIM details
When you purchase a SIMSOLO eSIM for USA, you will typically receive a QR code or a manual activation code via email or through the SIMSOLO app. This code is necessary to activate the eSIM on your phone.
3. Open your phone’s settings
- For iPhone:
- Open Settings.
- Tap Cellular or Mobile Data.
- Tap Add Cellular Plan.
- For Android:
- Open Settings.
- Tap Network & Internet.
- Select Mobile Network.
- Tap Add Carrier or Add eSIM.
4. Scan the eSIM QR Code
- For iPhone:
- After tapping Add Cellular Plan, use your phone’s camera to scan the QR code that you received from SIMSOLO.
- If you received a manual activation code instead, tap Enter Details Manually and input the information provided by SIMSOLO.
- For Android:
- Select Scan QR Code (if prompted).
- Use your phone’s camera to scan the QR code.
5. Confirm Activation
Once your phone scans the QR code or you enter the details manually, follow the on-screen instructions to confirm the eSIM activation. You may be asked to label your plan (e.g., “Main Plan” or “Travel Plan”).
6. Set Up Your eSIM Plan
Once activated, your eSIM will appear in the Mobile Network section. You can set your eSIM as the default line for data, calls, and text messages, or you can manage it based on your preferences (e.g., using eSIM for data and your physical SIM for calls).
7. Restart Your Phone
To finalize the process, restart your phone. This ensures that the eSIM is properly registered with your mobile network.
8. Test Your Connection
After your phone restarts, check if the eSIM is connected to the network. You should see the network name in the status bar, and you can test it by accessing the internet or making a call.
