The short answer is yes, you absolutely can keep your phone number with Holafly, but there are some important details to understand about how this works. After using Holafly eSIMs across more than 20 countries during our family travels, we've learned exactly how phone numbers work with eSIM technology and what travelers need to know. ## The short answer: yes, you keep your phone number Holafly provides data-only eSIM plans, which means your existing phone number stays active on your primary SIM or eSIM line. Your Holafly eSIM runs alongside it, handling your data while your home number handles calls and texts. Two lines, one device, no number changes. ### What this means in practice - Receive calls and texts on your regular number as normal - Use unlimited data through your Holafly eSIM - Avoid international roaming charges from your home carrier - Stay reachable to family, work, and anyone who already has your number ## How Dual SIM Technology Works with Holafly Modern smartphones support multiple SIM cards simultaneously, either through physical SIM slots or eSIM technology. Here's how it works with Holafly: ### Your Primary Line (Original Phone Number) - Handles voice calls and text messages - Keeps your familiar phone number - Can be set to roaming or airplane mode to avoid charges - Remains active for incoming calls and texts ### Your Holafly eSIM Line - Provides unlimited data connectivity - Handles all internet traffic - Supports video calls through apps like WhatsApp, FaceTime - No traditional calling or SMS capabilities This setup gives you the best of both worlds: familiar communication plus affordable international data. ## Setting up dual SIM with Holafly 1. ### Purchase your Holafly eSIM Buy your [Holafly eSIM](https://holafly.sjv.io/c/6317027/2233892/24764?subId1=do-you-keep-your-phone-number-with-holafly&subId2=howto-step&subId3=homepage&sharedid=esim-cluster&ref=adamandlinds.com) before you travel. Use code **ADAMANDLINDS** for 5% off. 2. ### Install the eSIM profile Scan the QR code from your confirmation email to install the Holafly eSIM. Do not enable data roaming yet. 3. ### Check your home carrier's roaming settings Contact your carrier about international roaming options for calls and texts. You'll want your primary line active for incoming calls, but data roaming turned off to avoid charges. 4. ### Test both lines before departure Confirm your Holafly eSIM appears in your cellular settings and your primary SIM is still active. Better to find issues at home than at the airport. 5. ### Enable data roaming on Holafly only Once you land, enable data roaming on your Holafly eSIM line. Keep data roaming disabled on your primary line to avoid charges from your home carrier. 6. ### Set Holafly as your data line In your cellular settings, set the Holafly eSIM as your default data line. Your primary SIM handles calls and texts. Holafly handles everything else.

Keeping your primary line active ensures continued access to: - Online banking platforms - Investment accounts - Payment apps like Venmo or PayPal - Cryptocurrency exchanges ### Social Media and Communication - **WhatsApp**: Tied to your original phone number - **Telegram**: Uses your primary number for verification - **Signal**: Requires your regular phone number - **Instagram/Facebook**: Two-factor authentication through your original number ### Travel and Transportation Apps - **Uber/Lyft**: Account verification through your primary number - **Airbnb**: Host communication and verification - **Airline apps**: Flight updates and check-in notifications - **Hotel booking platforms**: Confirmation and support communications ## Troubleshooting Common Phone Number Issues ### Why am I not receiving texts on my original number? Your primary line needs roaming enabled for SMS but not for data. Contact your carrier to confirm international texting is active on your plan — some carriers disable it by default or require you to opt in before travel. ### Why am I still getting roaming charges even with Holafly? Check that cellular data is fully disabled on your primary SIM line and enabled only on the Holafly eSIM. It's a common setup mistake and easy to miss in the cellular settings menu. ### Some apps aren't working with my original number. What do I do? Some apps require data on the same line as your phone number for verification. Try enabling WiFi calling on your primary line, or temporarily enable data roaming on it for the verification step, then disable it again immediately after. ### I can't switch between lines. What's wrong? Check that both eSIM profiles are properly installed and clearly labelled in your settings — something like "Home" and "Holafly" makes it easier to identify which is which. If one isn't showing, you may need to reinstall the profile. ## Best Practices for Phone Number Management ### Before You Travel - **Screenshot important settings** for easy reference - **Download offline maps** to reduce data dependency - **Set up WiFi calling** with your primary carrier - **Test dual SIM functionality** while still at home ### While Traveling - **Monitor both lines** for unexpected charges - **Use airplane mode strategically** when you only need WiFi - **Keep emergency contacts** accessible on both lines - **Update family and friends** about your connectivity setup ### Upon Return - **Review carrier charges** for any unexpected fees - **Deactivate Holafly eSIM** if no longer needed - **Restore original settings** on your primary line - **Keep eSIM profile** for future trips to same region ## Cost Comparison: Keeping Your Number vs. New Number ### Using Holafly with Your Existing Number - **Holafly eSIM**: $1.99-4.99/day depending on destination - **Carrier text/call roaming**: $0.25-2.00 per text, $1-3 per minute - **Total daily cost**: $5-15 for moderate usage - **Benefits**: Keep familiar number, no setup hassle ### Getting a New Local Number - **Local SIM card**: $20-50 initial cost - **Monthly service**: $30-60 depending on country - **Setup complexity**: High, requires carrier store visit - **Number management**: Must notify all contacts of temporary number ## Frequently Asked Questions ### Do you lose your phone number when using Holafly eSIM?
