Direct Confirmation: Yes, travel eSIMs allow you to connect instantly to high-speed 4G mobile networks across 15+ international destinations without removing your physical Singapore SIM card. By running a dual-SIM setup, your primary phone number remains active for urgent bank 2FA one-time passwords (OTPs) while your travel data routes through an affordable prepaid eSIM.
International travel has permanently evolved beyond plastic roaming SIM cards. Gone are the days of queueing at crowded airport arrival kiosks, filling out paper registration forms, and fumbling with delicate metal ejector pins only to misplace your tiny domestic SIM card in your luggage. With digital eSIM (Embedded Subscriber Identity Module) technology, your mobile connectivity is provisioned via software before your flight departs.
However, purchasing a travel eSIM without verifying device hardware and carrier lock settings introduces severe financial and operational risks. If your handset is carrier-locked or lacks an embedded eUICC chip, the digital profile cannot install, leaving you completely disconnected upon touchdown. This comprehensive Singapore guide provides the mandatory 10-second compatibility test, a master list of supported smartphones, step-by-step iOS and Android activation instructions, and full details on DigiStoreSG's 15-destination travel eSIM catalog.

Does Your Phone Support eSIM? The 10-Second Compatibility Dial Test
Before purchasing any digital travel data plan, verify that your device possesses the internal hardware required to store digital profiles. You do not need to dig through complicated nested system settings; you can confirm hardware readiness in ten seconds using standard universal dialer codes.
The Universal 10-Second Dial Test
- Open your phone's default Phone / Call Dialer application.
- Type the key sequence
*#06#into the keypad. You do not need to press the green call button; the device information screen triggers automatically. - Inspect the displayed parameters. If you see an entry labeled EID (Embedded Identity Document) accompanied by a barcode and a 32-digit alphanumeric code, your smartphone contains an eSIM chip and supports digital travel plans. If your screen only displays
IMEI1,IMEI2, andMEIDwithout any EID entry, your phone lacks eSIM hardware.
The Carrier Lock Trap (Crucial Verification)
Having an EID chip is only half the requirement. Your smartphone must also be carrier-unlocked. Devices bought under overseas installment contracts or subsidized telco lock-ins will reject foreign travel profiles even if the EID hardware is present.
- Apple iPhone Check: Navigate to Settings > General > About. Scroll down to the Carrier Lock (or Network Provider Lock) field. It must state “No SIM restrictions”. If it displays a carrier name, contact your telco to unlock the phone before traveling.
- Samsung & Android Check: Navigate to Settings > Connections > Mobile Networks > Network Operators. Verify that manual carrier selection is allowed, or insert a SIM from an alternate carrier to ensure it connects without prompting for an unlock code.

Step-by-Step Activation Guide: From Order to Touchdown
Activating a DigiStoreSG travel eSIM is completely digital and completed in two distinct phases: pre-flight profile installation at home over Wi-Fi, followed by network activation upon touchdown.
Phase 1: Pre-Departure Installation (At Home Over Wi-Fi)
1. Select your target country and validity plan from the DigiStoreSG store. Complete payment to receive your high-resolution QR code via email within minutes.
2. Display the received QR code on a secondary screen (laptop, tablet, monitor) or print it out. Your smartphone camera must be free to scan it.
3. For iPhone: Go to Settings > Cellular (or Mobile Data) > Add eSIM > Use QR Code. Point your camera at the QR code. Once recognized, label the line “Travel” or your destination name (e.g., “Japan Data”).
4. For Samsung Galaxy: Go to Settings > Connections > SIM manager > Add eSIM > Scan QR code. Align the viewfinder with the QR code and tap Add.
⚠️ CRITICAL PRE-FLIGHT RULE: Leave “Data Roaming” OFF for this new travel line while you remain in Singapore. Your plan validity only begins counting down once the profile connects to the destination local network.
Phase 2: Touchdown Activation (Upon Landing at Destination)
1. Once the aircraft lands and taxiing commences, turn off Airplane Mode.
2. In your device settings, switch Mobile Data to your DigiStoreSG travel eSIM line.
3. Ensure your Default Voice Line remains assigned to your domestic Singapore SIM card. This ensures incoming SMS, WhatsApp verifications, and Singapore bank 2FA OTPs route to your primary number seamlessly without incurring data roaming charges.
4. Toggle Data Roaming to ON exclusively for your DigiStoreSG travel eSIM. Within 30 to 60 seconds, your device will handshake with the local partner telco (e.g., Softbank in Japan, AIS in Thailand, Telkomsel in Indonesia) and deliver full 4G high-speed internet.

Frequently Asked Questions (FAQ)
Q1: Can I keep my Singapore WhatsApp number and receive bank OTPs?
Yes. On dual-SIM phones, leave your primary Singapore line active for voice and SMS while selecting the DigiStoreSG eSIM exclusively for Mobile Data. Your WhatsApp remains tied to your Singapore number without any changes, and incoming Singapore SMS or bank 2FA OTPs arrive normally without incurring data roaming fees.
Q2: When should I install the eSIM QR code before my trip?
We recommend scanning and installing the QR code 1 to 2 days before departure while connected to stable home Wi-Fi. Ensure Data Roaming for the travel eSIM remains turned OFF until you actually land in the destination country. Plan validity starts only upon local network handshake.
Q3: Can I re-scan the QR code if I accidentally delete the eSIM profile?
No. Like virtually all international travel eSIM profiles, each QR code is a single-use digital authorization token. Once added to a phone, do not tap “Delete eSIM” or “Remove Cellular Plan”. If you experience connection issues on landing, toggle Airplane Mode or manually select the partner network rather than deleting the profile.
Q4: Does the travel eSIM include voice calls or regular SMS?
Our travel eSIMs are high-speed prepaid data-only plans. They do not come with an international voice telephone number. For voice calls and messaging, use VoIP applications such as WhatsApp, Telegram, FaceTime, Zoom, or Skype, which run seamlessly over 4G data.
Q5: Can foreign buyers outside Singapore purchase these eSIMs?
Yes. All DigiStoreSG eSIM products are published to our International Market and classified as digital items. Foreign travelers worldwide can purchase with credit card, PayPal, or Shop Pay with zero shipping fees, receiving the activation QR code electronically in their email inbox.
Q6: Can I share my data via mobile hotspot / personal tethering?
Yes. Mobile hotspot sharing is fully supported across all 15 destinations on compatible unlocked devices, allowing you to share high-speed data with your laptop, iPad, or travel companions.
