The Case for Keeping Your Physical SIM Card
For many travelers, leaving the physical SIM in the phone is the preferred option. It offers a blend of connectivity and convenience, as long as you manage your settings correctly.
Stay Reachable: Receiving Calls and Texts (SMS)
The biggest advantage of keeping your physical SIM is maintaining access to your primary phone number. This is crucial for several reasons:
- Two-Factor Authentication (2FA): Many banks, social media accounts, and email services like Gmail send verification codes via SMS to log in from a new location. Without your primary SIM, you could get locked out of essential accounts.
- Important Calls & Messages: You won’t miss urgent calls or texts from family, your bank, or other important contacts. While you may not want to answer calls to avoid high fees, you can see who is calling and decide if it’s an emergency.
Seamless Transition Home
When you land back home, the last thing you want to do is fumble around for a tiny piece of plastic. By leaving your physical SIM in, you can simply switch your phone’s settings back to your primary line in seconds. There’s no risk of losing your SIM card, which can be a hassle to replace.
How to Manage Dual SIM Settings to Avoid Charges
This is the most critical step if you keep your SIM in. To prevent surprise roaming bills, you must configure your phone’s settings properly. Here’s a general guide for a dual SIM setup:
- Label Your Plans: Name your eSIM something like “Travel Data” or “Yoho Mobile” to easily distinguish it from your primary line.
- Set eSIM for Mobile Data: Go to your phone’s cellular settings and select your eSIM as the primary line for mobile data.
- Turn Off Data Roaming on Your Physical SIM: This is essential. Navigate to the settings for your physical SIM line and ensure the “Data Roaming” toggle is switched OFF. This prevents it from using data networks abroad.
By doing this, you can safely use your Yoho Mobile eSIM for all your data needs in places like Europe or Asia while keeping your home number active for calls and texts.
The Case for Removing Your Physical SIM Card
If the thought of a potential four-figure phone bill gives you anxiety, removing your physical SIM card offers complete peace of mind. It’s the most straightforward, foolproof method to guarantee you won’t face any accidental charges.
The Ultimate Safeguard Against Accidental Roaming Fees
Even with data roaming turned off, software glitches or accidental setting changes can sometimes lead to unintended data usage. As the GSMA (Groupe Spéciale Mobile Association) notes, network configurations can be complex. Removing the physical SIM card eliminates this risk entirely. The card is not in the phone, so it cannot connect to any foreign network for any reason. It’s the digital equivalent of unplugging an appliance from the wall.
Simplifying Your Phone’s Connectivity
For some users, managing dual SIM profiles, primary lines, and default voice lines can be confusing. Taking out your home SIM simplifies everything. Your phone will operate with only one line—your travel eSIM. This means you don’t have to double-check which line you’re using for data or worry about complex settings. All connectivity will default to the only available option, making for a much simpler user experience.
Yoho Mobile’s Recommendation: The Best of Both Worlds
So, what’s the final verdict? For most users, we recommend keeping your physical SIM in your phone but being diligent about your settings.
The ability to receive critical 2FA texts and important calls on your home number is a massive benefit that often outweighs the small risk of accidental charges—a risk you can virtually eliminate by correctly configuring your device.

Frequently Asked Questions (FAQ)
Q1: Can I use my eSIM for data and my physical SIM for calls at the same time?
Yes, absolutely. Modern dual SIM phones are designed for this. You can set your Yoho Mobile eSIM as the primary for mobile data while leaving your physical SIM as the default for voice calls and texts. This setup allows you to browse and use apps with your affordable travel data while still being reachable on your regular phone number.
Q2: What’s the safest way to use dual SIM abroad without getting charged for roaming?
The safest way is to go into your phone’s cellular settings, select your physical (home) SIM, and ensure the “Data Roaming” option is turned OFF. Then, select your travel eSIM and set it as the designated line for all mobile data usage. This prevents your home plan from connecting to data networks abroad.
Q3: Will I still get texts on my primary number if I remove the physical SIM?
No. Once you remove your physical SIM card, it is completely disconnected from any cellular network. You will not be able to receive any calls or SMS messages sent to that number until you reinsert the SIM card into a phone.
Q4: How do I turn off data roaming on my physical SIM?
On an iPhone, go to Settings > Cellular. Tap on your primary (physical SIM) line, and then toggle Data Roaming to the off position. On Android devices, the path is usually Settings > Network & Internet > SIMs. Select your physical SIM and turn off the Roaming toggle. The exact steps may vary slightly by manufacturer.
Conclusion: Travel Smarter, Not Harder
Deciding whether to remove your physical SIM card when using an eSIM abroad comes down to a trade-off between convenience and caution.
- Keep it in if you need to receive SMS for two-factor authentication or stay reachable on your home number. Just be meticulous about turning off data roaming on that line.
- Take it out if you want absolute certainty that you won’t face any surprise roaming charges and prefer a simpler phone setup.
