2. Which is the best eSIM for Singapore?
The best Singapore eSIM depends on your usage needs. Short-term visitors can opt for 1–5 GB plans ideal for messaging and navigation.

3. What should I look for when comparing different travel eSIMs for Singapore?
Compare by data volume (1–30 GB +), validity (3–30 days), speed (4G/5G), coverage (Singtel/StarHub/M1), hotspot support, and price per GB. Also check if customer support is included. Mobimatter lists all these details clearly, so you can choose smartly. Frequent travelers should focus on value and flexibility, while casual users can save with smaller plans. Decide what matters most—speed, coverage, or cost—and pick accordingly for smooth, stress-free connectivity.
4. Do I need to provide ID or documents to buy a Singapore travel eSIM?
No ID is required. With Mobimatter, you only need an email to receive your QR code and instructions. Skip the long lines and paperwork usually needed at local stores. The eSIM buying process is 100% digital, fast, and private—ideal for international visitors who want to stay connected instantly without delays or language barriers.
5. Can I buy an eSIM for Singapore before my trip?
Yes, buying in advance is highly recommended. Mobimatter lets you purchase and install the eSIM before you travel. You’ll receive your QR code immediately; install it while connected to Wi-Fi and activate it once you land in Singapore. That means no airport kiosks, no roaming worries, and instant connectivity upon arrival—perfect for booking rides, checking maps, or contacting friends right after landing.
6. How do I install and activate my Singapore eSIM?
First, connect to Wi-Fi. On iPhone: Settings → Cellular → Add eSIM → Scan QR. On Android: Settings → Network & Internet → SIM Manager → Add eSIM → Scan QR. Mobimatter also provides a manual option using the SM-DP+ server and activation code. Label your plan (e.g., “Singapore eSIM”) for easy management. Don’t activate until you arrive in Singapore to preserve validity. Activation takes under a minute—then you’ll have 4G/5G data on local networks.
7. Should I activate my Singapore eSIM before or after I arrive?
Install before you fly, activate after landing. Activation starts the validity countdown, so doing it early can waste days. Once you arrive in Singapore, connect to Wi-Fi at the airport or hotel and turn it on. Mobimatter’s setup guide explains timing clearly so you get full data duration. This simple step ensures maximum value and zero network conflicts.
8. How do I activate my Singapore eSIM using a QR code?
Activation via QR is fast. Connect to Wi-Fi, then open eSIM settings. On iPhone: Settings → Cellular → Add eSIM → Scan QR. On Android: Settings → Network → SIM Manager → Add eSIM → Scan QR. Point your camera at the code Mobimatter sent. Confirm and label the plan. Within a minute, you’ll be connected to Singapore’s local networks with 4G/5G speeds.
9. What if I can’t scan the QR code for my Singapore eSIM?
No problem. Mobimatter provides manual installation details—SM-DP+ server address and activation code. Go to eSIM settings, choose “Add eSIM manually,” and enter the data exactly. This is handy if your device camera fails or QR scanning isn’t supported. Manual setup takes just minutes and connects you instantly. Full instructions are available in your Mobimatter dashboard.
10. How do I switch between my primary SIM and my Singapore eSIM?
Go to SIM Manager or Cellular Settings and you’ll see both SIMs. Set your Singapore eSIM as the default for mobile data, and keep your home SIM active for calls/SMS if you wish. Switching back is as simple as toggling the settings. This flexibility helps you stay reachable on your main number while enjoying cheap local data.
11. How do I avoid roaming charges while using a Singapore eSIM?
Before arrival, go to Mobile Data Settings and select your Singapore eSIM as the default data line. Then turn off “Data Roaming” for your primary SIM. This forces all data through the Singapore eSIM, avoiding expensive roaming fees. Mobimatter’s guide covers this setup step-by-step, ensuring all apps use your local plan safely.
12. What is a travel eSIM and how does it work in Singapore?
A travel eSIM is a digital SIM inside your phone that connects to local networks like Singtel, M1, and StarHub without needing a physical card. Buy it online, scan a QR code, and you’re ready to go. No store visits, no ID checks—just instant connectivity. It’s ideal for tourists, remote workers, and frequent flyers who want fast data right after landing.
13. Why should I use a Singapore eSIM instead of my home carrier’s roaming plan?
Roaming is costly and inconsistent. A Singapore travel eSIM is up to 80% cheaper, offers local network speed, and gives transparent pricing with no hidden fees. You can activate it instantly on arrival and use apps, navigation, or video calls without worrying about bill shocks. It’s faster, cheaper, and more reliable than international roaming.
14. Is a Singapore eSIM cheaper than roaming with my carrier?
Absolutely. eSIM plans in Singapore are priced like local SIMs and often cost a fraction of international roaming rates. With Mobimatter, you pay upfront and know exactly what you get—no surprises. Even a single day of roaming can cost more than a week of eSIM usage. It’s the smart, budget-friendly choice for data abroad.
15. What’s the difference between a Singapore travel eSIM and a local SIM card?
A travel eSIM is completely digital—buy and activate it online in minutes. A physical SIM requires a store visit, paperwork, and manual insertion. With an eSIM, you can keep your home SIM active for calls and use Singapore data simultaneously. It’s faster, safer, and more convenient—ideal for modern travelers who prefer flexibility and speed.
16. Can I use a Singapore eSIM and my regular SIM card at the same time?
Yes, most modern smartphones support dual SIM functionality—one physical SIM and one eSIM. You can keep your home SIM active for calls or SMS while using your Singapore eSIM for mobile data. This setup is ideal for staying in touch with family, banks, or work contacts without paying roaming charges. Just assign your Singapore eSIM for data in SIM settings, and your phone will manage both seamlessly.
17. Will I get a new phone number with a Singapore travel eSIM?
Most Singapore travel eSIMs from Mobimatter are data-only and do not include a local phone number. These plans are perfect for internet use, messaging apps, and video calls via WhatsApp, FaceTime, or Skype. If you require voice or SMS functionality, check plan details for calling options or VoIP support. Otherwise, your existing SIM can stay active for receiving texts or calls while abroad.
18. Can I still receive calls and texts on my original number while using a Singapore eSIM for data?
Yes, as long as your phone supports dual SIM mode and your home SIM stays inserted, you can still receive calls and SMS on your original number. Keep data roaming turned off on your home SIM to avoid unwanted charges. Assign the Singapore eSIM for mobile data only. This lets you maintain full connectivity for calls, messages, and apps—without roaming costs.
19. Do Singapore travel eSIMs include calls and SMS, or are they data-only?
Most Singapore eSIMs from Mobimatter are data-only and don’t include voice or SMS services. However, internet-based apps like WhatsApp, Telegram, or FaceTime Audio work perfectly over data. Some plans may offer limited voice or SMS bundles, but they’re rare. Always read the plan description to confirm. For most travelers, data-only eSIMs are more than enough for navigation, communication, and streaming while in Singapore.
20. How much data will I need for my trip to Singapore?
It depends on your travel style. Light users who just check maps and messages can manage with 3–5 GB. Moderate users browsing and using social media may need 10–15 GB. Heavy users who stream or work online should consider 20–30 GB. Mobimatter offers flexible data sizes so you can choose what suits your trip. It’s smart to buy slightly more than you expect to avoid top-ups or slow speeds later.
21. Is my phone unlocked and compatible with Singapore eSIMs?
To use a Singapore eSIM, your phone must be both unlocked and eSIM-compatible. Most newer smartphones from 2020 onward qualify. For Apple, iPhone XS/XR and newer models work with eSIM. For Android, Google Pixel 3+, Samsung Galaxy S20+, and newer Huawei, Oppo, and Xiaomi models support it too. To check, go to Settings → Cellular or Network → Add eSIM. If the option appears, your device supports eSIM.
22. What is an eSIM card and how does it work in Singapore?
An eSIM is a built-in digital SIM card that lets your phone connect to networks without using a physical chip. In Singapore, it connects you to carriers like Singtel, StarHub, or M1. After buying online, you get a QR code or manual activation info from Mobimatter. Once installed and activated, your device connects to local networks just like a regular SIM—fast, simple, and fully remote.
23. How to activate eSIM on an iPhone in Singapore?
To activate your eSIM on iPhone, connect to Wi-Fi and go to Settings → Cellular → Add eSIM. Choose “Use QR Code” and scan the QR provided by Mobimatter. You can also enter activation details manually. Label your plan as “Singapore eSIM” and set it as your primary data line. Activation usually completes within minutes and connects you to local 4G/5G networks.
24. How to transfer eSIM from one iPhone to another iPhone in Singapore?
To move your Singapore eSIM to a new iPhone, first remove it from your old device via Settings → Cellular → Select Plan → Remove Cellular Plan. Then, log in to your Mobimatter dashboard and request a replacement QR code. On your new iPhone, scan the new code via Settings → Cellular → Add eSIM. Label it properly (e.g., “Singapore Travel”) and activate it for data. The process takes just a few minutes and ensures seamless continuity.
25. Which phones support eSIM in Singapore?
Most modern smartphones now support eSIM. Compatible models include Apple iPhone XS, XR, and newer (including iPhone 11–15), Google Pixel 3a–8 series, and Samsung Galaxy S20, S21, Z Fold, and Flip models. Flagships from Huawei, Oppo, and Xiaomi also support eSIM in Singapore. To check compatibility, go to your phone’s settings → Add eSIM. If available, you’re good to go.
26. How to transfer eSIM from iPhone to Android in Singapore?
You can’t directly transfer an eSIM between iPhone and Android due to platform limits. Instead, delete it from your old phone, then request a new QR code in your Mobimatter account. On Android, go to Settings → Network → SIM Manager → Add eSIM → Scan QR. You can also use manual activation details. Label the plan as “Singapore eSIM” and activate it for data. This quick process ensures you stay connected after switching devices.
27. How to delete eSIM from an iPhone used in Singapore?
To remove your Singapore eSIM, go to Settings → Cellular → Select Plan → Remove Cellular Plan. Confirm deletion to clear it from your phone. This removes the eSIM profile but doesn’t cancel the plan itself. If you plan to reinstall later, request a new QR from Mobimatter. Deleting old or expired eSIMs helps keep your phone tidy and prevents confusion with active ones.
28. How to set up eSIM on an iPhone while in Singapore?
To set up, connect to Wi-Fi and open Settings → Cellular → Add eSIM. Choose “Use QR Code” and scan the one from Mobimatter, or enter activation details manually. Label the plan (e.g., “Singapore eSIM”) and set it for data. Once activated, your iPhone connects to local networks instantly. The setup is quick and requires no store visits or extra hardware.
29. How to add eSIM to an iPhone while traveling to Singapore?
Adding a Singapore eSIM while traveling is quick and convenient. Connect your iPhone to Wi-Fi—either at home, at the airport, or during your flight—and go to Settings → Cellular → Add eSIM. Scan the QR code provided by Mobimatter, or use the manual activation details (SM-DP+ server and activation code) if scanning isn’t possible. Once added, label the plan as “Singapore eSIM,” but wait to activate mobile data until you land. This ensures full validity and instant connectivity upon arrival in Singapore.
30. Is my phone eSIM compatible for use in Singapore?
To confirm compatibility, go to Settings → Cellular (or Network & Internet) → Add eSIM. If that option appears, your device supports eSIM. Ensure it’s unlocked too, as carrier-locked phones can block eSIM activation. Supported models include iPhone XS and newer, Google Pixel 3+, Samsung Galaxy S20+, and other modern Android flagships. Always check before purchasing to ensure smooth activation and use in Singapore.
