Do I Need to Keep My Primary SIM Active When Using a Yoho Mobile eSIM?

Planning international travel often brings up questions about staying connected. You’ve discovered the convenience of a Yoho Mobile data eSIM for affordable internet abroad, but what about your primary phone number? Do you need to keep your home physical SIM card active? It’s a common concern for travelers wanting seamless connectivity without surprise bills.

This guide clarifies how your primary SIM and Yoho Mobile eSIM work together in a dual SIM setup, helping you decide the best approach for your trip and understand how to use your primary SIM with an eSIM effectively.

Understanding Dual SIM and eSIM Technology

Most modern smartphones support Dual SIM functionality, meaning they can use two separate mobile lines simultaneously. This is often achieved through one physical SIM slot and one embedded SIM (eSIM), or sometimes two eSIMs. You can learn more about the basics in our guide, What is an eSIM Card?.

This technology is incredibly useful for travelers. You can keep your primary number for potential calls or texts while using a local or regional data eSIM, like those from Yoho Mobile, for affordable mobile data. This setup avoids the hassle of swapping physical SIMs and often provides better rates than traditional international roaming. For a deeper dive, check out our eSIM vs Physical SIM comparison.

Before you travel, ensure your device is unlocked and supports eSIM technology. You can verify compatibility on our eSIM compatible devices list. Major manufacturers like Apple and Google provide detailed support pages on managing dual SIM functionality (See Apple’s guide for reference).

To Keep Active or Not? Your Primary SIM Choice

The core question isn’t whether you can keep your primary SIM active – you usually can – but whether you should. The decision depends entirely on your need to receive calls and SMS messages on your primary phone number while traveling.

Scenario 1: Keeping Your Primary SIM Active

• Pros: You can receive incoming calls and SMS messages on your home number. This is crucial if you expect important calls or verification texts (like from banks).
• Cons: Your primary carrier will likely charge you international roaming fees for any calls you answer or make, and potentially even for received SMS messages (check their policy!). Keeping two lines active can also consume more battery.
• How it works: You’ll configure your phone to use the Yoho Mobile eSIM for Cellular Data, while leaving your primary line active for voice calls and SMS. This is a key aspect of how to use dual SIM while traveling if you need home number access.

Scenario 2: Disabling or Turning Off Your Primary SIM

• Pros: You completely avoid potential roaming charges from your primary carrier. This can lead to significant savings and potentially better battery life.
• Cons: You will not receive calls or standard SMS messages sent to your primary number while the line is inactive. (Note: Services like iMessage or WhatsApp calling work over data, so they’ll function using your Yoho Mobile eSIM data).
• How it works: You’ll either physically remove your primary SIM (if applicable) or, more commonly, disable the line in your phone’s cellular settings before or upon arrival. You will rely solely on your Yoho Mobile eSIM for data connectivity.

Choosing whether to keep your phone number active abroad involves balancing accessibility with cost. If you don’t need immediate access to calls/SMS on your home number, disabling the primary SIM is the most cost-effective approach for using your Yoho Mobile dual SIM setup primarily for data.

How to Manage Dual SIM Settings for International Travel

Properly configuring your dual SIM settings for international travel data is crucial. While specific steps vary slightly between iOS and Android, the principles are the same:

1. Install Your Yoho Mobile eSIM: Follow the instructions, typically involving scanning a QR code, before you depart or upon arrival using Wi-Fi. Need help? See our guides for iOS and Android.
2. Label Your Lines: Name your SIMs clearly (e.g., “Primary”, “Yoho Travel”). This avoids confusion.
3. Set Default Lines: Choose default lines for Voice, SMS, and Cellular Data.
   • Crucially, set ‘Cellular Data’ to your Yoho Mobile eSIM. This ensures you use the affordable travel data plan.
   • Set ‘Default Voice Line’ based on your choice in the previous section. If keeping the primary active, you might keep it as the default or choose ‘Ask Every Time’. If disabling the primary, set it to Yoho Mobile (if it supports calling) or another option if available.
4. Manage Primary Line Roaming: If keeping your primary SIM active (Scenario 1), ensure ‘Data Roaming’ is turned OFF for your primary line in your phone settings to prevent accidental data usage charges from your home carrier. Let Yoho handle the data!

These settings allow you to effectively receive calls on your primary number with a travel eSIM providing the data, or to completely isolate your primary SIM from roaming charges.

Frequently Asked Questions (FAQ)

Q1: Can I receive calls on my regular number if I use a Yoho Mobile data eSIM?

Yes, you can receive calls on your primary number with a travel eSIM like Yoho Mobile if you keep your primary SIM line active in your phone’s dual SIM settings. However, be aware that your home carrier will likely charge you international roaming fees for these calls.

Q2: How do I set up my phone for dual SIM use with Yoho Mobile abroad?

First, install your Yoho Mobile eSIM. Then, go into your phone’s Cellular/Mobile Network settings. Label your lines (e.g., Primary, Yoho Travel). Most importantly, set ‘Cellular Data’ to use the Yoho Mobile eSIM line. Decide if you want to keep your primary line active for calls/SMS (beware of roaming fees) or disable it to avoid charges. Always turn off Data Roaming for your primary line.

Q3: Will keeping my primary SIM active drain my battery faster when using a Yoho Mobile eSIM?

Keeping two cellular lines active simultaneously (your primary SIM and the Yoho Mobile eSIM) can consume slightly more battery power than using just one line, as the phone needs to maintain connections to both networks. The impact varies by device and network conditions, but disabling the line you don’t actively need (like your primary if only using data) can help conserve battery.

Q4: Do I need to remove my physical SIM card to use a Yoho Mobile eSIM?

No, you generally don’t need to remove your physical primary SIM card to use a Yoho Mobile eSIM, provided your phone supports Dual SIM with eSIM (one physical, one eSIM). You can manage both lines directly within your phone’s settings, enabling or disabling them as needed for your dual SIM setup.

Q5: What happens if I turn off my primary SIM line while traveling?

If you disable your primary SIM line in your phone’s settings, it will be inactive. You will not be able to make or receive calls or standard SMS messages on that number. You will also completely avoid any potential roaming charges from your primary carrier for that line. Your Yoho Mobile eSIM will continue to provide data connectivity independently.

Conclusion

Whether you need to keep your primary SIM active while using a Yoho Mobile eSIM boils down to personal choice and needs. If receiving calls and SMS on your home number is essential, keep the primary line active but be mindful of potential roaming charges from your home carrier and ensure data roaming is off for that line. If affordable data is your priority and you can manage communications via apps like WhatsApp or iMessage using your Yoho data, disabling your primary SIM line is the most cost-effective way to enjoy seamless travel connectivity.

Yoho Mobile provides the flexible, affordable data you need for your travels, working perfectly within your device’s dual SIM capabilities. Choose the setup that best suits your needs and enjoy your trip!
