Question 1

Do I need to delete my eSIM after my trip?

Accepted Answer

No, you don't need to delete it. Most providers let you keep the profile installed in case you return to that destination. eSIM profiles take up minimal space on your device. However, if you want to free up space, you can delete it from your cellular settings. Just make sure the plan is no longer active before deleting to avoid any issues. If you plan to visit the same country again, keeping it installed means you can simply reactivate or top up the existing profile without reinstalling.

Question 2

Can I use my eSIM in multiple devices?

Accepted Answer

Generally, no. Each eSIM profile is tied to a specific device through a unique identifier (EID). You cannot use the same eSIM profile on multiple devices simultaneously. If you want to transfer an eSIM to a new device, some providers allow profile transfers, but you typically need to contact customer support and the old profile will be deactivated. For families or groups, each person needs their own eSIM plan, though one person can share data via mobile hotspot if their plan allows tethering.

Question 3

How long does it take to activate an eSIM?

Accepted Answer

Installation takes 2-5 minutes once you have the QR code. You scan the code, the profile downloads over Wi-Fi (usually 10-30 seconds), and it installs automatically. However, network activation can vary: some eSIMs connect instantly when you turn them on, while others may take 5-15 minutes to fully activate and find a network. In rare cases, it can take up to an hour. If you're still not connected after an hour, contact your provider's support. To avoid stress, install your eSIM at home before your trip, not when you land.

Question 4

Can I use eSIM and physical SIM at the same time?

Accepted Answer

Yes, this is called dual SIM functionality, and it's one of the biggest advantages of eSIM. You can keep your home physical SIM active for calls and SMS while using the eSIM for data when traveling. Most modern phones support this: iPhone XS and newer, Samsung Galaxy S20+, Google Pixel 3+, and other recent flagships. In your phone settings, you choose which SIM to use for cellular data, calls, and messages. For travelers, the typical setup is: home SIM for voice/SMS (with data roaming OFF), eSIM for mobile data.

Question 5

What happens if I run out of data mid-trip?

Accepted Answer

Most eSIM providers let you top up or extend your plan instantly through their mobile app or website. You'll receive a notification when you're running low (typically at 80% usage), giving you time to purchase additional data. Top-ups are usually instant: you buy more data, it's added to your existing plan within seconds, and you continue using the same eSIM profile. Alternatively, you can install a backup eSIM from a different provider and switch over. It's a good practice to monitor your usage daily in the provider's app to avoid surprises.

Question 6

Should I download offline maps when traveling with an eSIM?

Accepted Answer

Yes, absolutely. Even with an eSIM providing data coverage, downloading offline maps before you travel is smart insurance. Offline maps save data (navigation apps consume significant amounts), work in areas with poor or no cell signal (mountains, rural areas, underground transit), and serve as a backup if you run out of data or have eSIM issues. They load instantly without waiting for data connection and help preserve battery life. Most importantly, they ensure you can always navigate confidently. Both Google Maps and Apple Maps offer offline functionality. Check out our complete step-by-step guide for downloading offline maps on both platforms before your trip.

Question 7

How much does an eSIM cost?

Accepted Answer

eSIM costs vary widely by destination, data amount, and validity period. As a general guideline: Weekend plans (1-3GB, 7 days): $5-10

Weekly plans (3-10GB, 7-15 days): $10-25

Monthly plans (10-50GB, 30 days): $25-60

Regional plans (Europe, Asia, etc.): $20-50 for 30 days. Popular destinations like Europe and Southeast Asia tend to be cheaper ($10-15 for a week), while less common destinations or small islands can be pricier ($25-40). Regional multi-country plans offer the best value for travelers visiting multiple countries.

Question 8

Are there unlimited eSIM plans?

Accepted Answer

Yes, some providers offer unlimited data plans, but read the fine print carefully. 'Unlimited' often means unlimited at full speed up to a certain threshold (e.g., 30GB), after which speeds are throttled to 2G/3G. True unlimited without any throttling exists but costs significantly more ($50-100+ per month). For most travelers, a generous fixed data plan (10-20GB) is more cost-effective than unlimited. If you need large amounts of data for remote work, look for high-cap plans (50-100GB) rather than unlimited, as they offer better value and predictable performance.

Question 9

Is eSIM cheaper than international roaming?

Accepted Answer

Yes, almost always. Carrier roaming typically costs $10-15 per day (so $70-140 for a week), while equivalent eSIM plans cost $10-30 for the entire week, which is a 75-90% saving. For example, AT&T charges $12/day for International Day Pass, totaling $84 for a week. A comparable eSIM with 5-10GB costs $15-25. The only scenario where roaming might make sense is a 1-2 day trip where setup time isn't worth the $10-20 saving, or if your employer reimburses travel expenses. For trips longer than 2 days, eSIM is significantly cheaper.

Question 10

Can I get a refund if I don't use my eSIM?

Accepted Answer

Refund policies vary by provider. Most eSIM plans are non-refundable once the QR code is delivered, similar to digital products. However, if you haven't installed or activated the profile, some providers may offer refunds within 24-48 hours. If there's a technical issue preventing activation, reputable providers will issue a new QR code or refund. Always check the provider's refund policy before purchasing. To minimize risk, start with a small plan to test the service, then buy a larger one if satisfied. Some providers offer 'try before you buy' mini plans for $5-7.

Question 11

Do eSIM plans automatically renew?

Accepted Answer

No, most travel eSIM plans are prepaid one-time purchases with fixed validity periods and do not auto-renew. Once your data runs out or the validity period expires, service stops and you need to manually purchase a new plan or top-up. This is different from traditional monthly mobile contracts. The advantage is no surprise charges or forgotten subscriptions. The disadvantage is you need to proactively monitor usage and renew before expiry. Set reminders in your phone for a few days before your plan expires so you can top up if needed.

Question 12

Will my eSIM work in all countries?

Accepted Answer

It depends on which plan you purchased. Each eSIM plan specifies which countries it covers. Single-country plans work only in that specific country. Regional plans cover multiple countries (e.g., 'Europe' plans typically cover 30+ European countries). Global plans cover 100-180 countries worldwide. Before purchasing, always check the provider's coverage map for your specific destinations. Most providers clearly list covered countries in the plan description. If you're visiting multiple countries, regional or global plans offer better value than buying separate plans for each country.

Question 13

Can I use eSIM on a locked phone?

Accepted Answer

It depends on what type of lock. Carrier-locked phones (purchased through a carrier contract) usually have eSIM functionality restricted until you unlock the phone with your carrier. Most carriers require you to complete your payment plan and be a customer for 30-90 days before unlocking. iCloud-locked or blacklisted phones will not work with any SIM or eSIM. To check if your phone is unlocked, go to Settings → About on iPhone, or try to install an eSIM from a different carrier. If the option is greyed out or unavailable, contact your carrier to request an unlock.

Question 14

Why is my eSIM not working even though I installed it?

Accepted Answer

Common reasons:

1) eSIM is installed but not activated: check that it's turned ON in your cellular settings and set as your data line.

2) Data roaming is disabled: some providers require data roaming to be enabled even though you're using a local profile.

3) You're not in the coverage area: verify your destination is included in your plan.

4) Network selection is automatic when it should be manual: try manually selecting a carrier network.

5) The plan hasn't been activated yet: some plans require manual activation in the provider's app.

6) You arrived before your plan's start date: check your plan validity. Try toggling airplane mode, restarting your device, and checking the provider's setup guide.

Question 15

Can I transfer my eSIM to a new phone?

Accepted Answer

It depends on your provider and devices. iPhone-to-iPhone transfers (iOS 16+): You can often transfer eSIMs directly during device setup or through Settings → Cellular → Transfer eSIM. This works seamlessly for carrier eSIMs but may not work for all travel eSIM providers. For Android or cross-platform transfers: Most travel eSIM profiles cannot be directly transferred. You'll need to contact your provider's customer support to request a new QR code for the new device. The old profile will be deactivated and a new one issued. Some providers charge a small fee ($2-5) for reissues. Always check your provider's transfer policy before switching devices mid-trip.

Question 16

Does using eSIM drain my battery faster?

Accepted Answer

Not significantly. eSIM uses the same cellular radio as a physical SIM, so battery consumption is essentially identical. However, using dual SIM mode (physical SIM + eSIM simultaneously) can cause slightly higher battery drain (5-10%) because your phone maintains connections to two networks. You can minimize this by disabling the SIM you're not actively using for data. Battery drain is more affected by signal strength. Weak signals cause your phone to boost power to maintain connection. If you notice unusual battery drain with eSIM, check that you're in an area with good coverage and disable the unused SIM.

Question 17

Will I get a phone number with my eSIM?

Accepted Answer

Most travel eSIM plans are data-only and do NOT include a phone number for voice calls or SMS. This is how providers keep costs low. You can still make calls using internet-based apps: WhatsApp, Skype, FaceTime Audio, Google Voice, or Telegram over data. Some providers offer add-ons for voice minutes or local numbers at extra cost, but this is less common. If you need a local number for deliveries, reservations, or local services, consider buying a cheap local physical SIM card in addition to your eSIM, or use a virtual number service like Google Voice or Skype.

Question 18

Can I receive SMS/text messages with an eSIM?

Accepted Answer

On data-only eSIMs (most travel eSIMs): No, you cannot receive SMS because you don't have a phone number attached to the eSIM. However, you CAN receive SMS on your home SIM if you're using dual SIM mode (home physical SIM + travel eSIM). Keep your home SIM active, turn off data roaming on it, and SMS/calls will still come through. This is perfect for receiving bank verification codes and two-factor authentication messages. For messaging, use internet apps like WhatsApp, iMessage, or Telegram that work over your eSIM's data connection.

Question 19

Can I share my eSIM data with other devices (hotspot)?

Accepted Answer

It depends on your plan. Many eSIM plans allow tethering/mobile hotspot, but some budget plans explicitly restrict it. Check your plan's terms before purchasing if you need hotspot functionality. To use hotspot: iPhone: Settings → Personal Hotspot → Turn on. Android: Settings → Network & Internet → Hotspot & tethering. When hotspot is enabled, other devices (laptops, tablets, other phones) can connect to your phone's internet. This is great for families. One person buys a large eSIM plan and shares it with everyone via hotspot, saving money on multiple plans. Monitor usage carefully as hotspot can burn through data quickly.

Question 20

Does eSIM support 5G?

Accepted Answer

Yes, if three conditions are met:

1) Your device supports 5G hardware (iPhone 12+, recent Samsung/Pixel flagships).

2) The eSIM provider's partner networks offer 5G in your destination.

3) Your plan includes 5G access (some budget plans may be limited to 4G/LTE). 5G availability varies significantly by country. It's common in major cities in the US, Europe, Korea, and Japan, but limited in developing countries. Even on 5G-capable plans, you'll fall back to 4G/LTE when 5G isn't available. For most travel use cases (maps, messaging, browsing), 4G/LTE is perfectly sufficient. 5G matters more if you're streaming HD video or running video conferences.

Question 21

Can I use my eSIM for WhatsApp calls and video calls?

Accepted Answer

Absolutely, yes. WhatsApp, FaceTime, Skype, Zoom, Google Meet, and all internet-based communication apps work perfectly over eSIM data. In fact, this is the recommended way to make calls with data-only eSIM plans. WhatsApp calls use about 0.5-1 MB per minute for voice and 5-8 MB per minute for video. Make sure the person you're calling also has the app installed. If you need to call regular phone numbers that aren't on WhatsApp, use services like Skype Credit, Google Voice (US), or WhatsApp Business calling features. Quality depends on your data speed. 4G/LTE provides excellent quality.

Question 22

Can I have multiple eSIMs installed?

Accepted Answer

Yes. Most modern phones can store 5-10 eSIM profiles simultaneously. However, you can only use 1-2 at a time depending on your device: iPhones support 1 physical SIM + 1 eSIM active (or 2 eSIMs on iPhone 13+ in the US). Many Android phones support 1 physical + 1 eSIM active. You can switch between stored eSIMs instantly in your settings without reinstalling. This is great for frequent travelers. Keep eSIMs for countries you visit regularly installed, and just toggle them on when you arrive. Delete old/expired profiles periodically to free up space.

Question 23

Is it safe to buy eSIMs online?

Accepted Answer

Yes, when you purchase from reputable providers. Stick with well-known eSIM marketplaces: Airalo, Holafly, Nomad, Ubigi, GigSky, or major carriers. These use secure payment processing (encrypted transactions, PCI-compliant). Avoid: QR codes from unknown sellers on social media, super-cheap deals that seem too good to be true, or providers with no website/customer support. Check reviews on Trustpilot or Reddit before buying. Red flags include: no company information, spelling errors, requests for unnecessary personal data, or payment via non-standard methods. Legitimate providers deliver QR codes instantly via email after purchase.

Question 24

Can my eSIM be hacked or stolen?

Accepted Answer

eSIMs are generally more secure than physical SIM cards because they can't be physically removed from your device. However, risks exist:

1) QR code theft: if someone gets your activation QR code, they could potentially install it on another device before you do. Keep QR codes secure and delete emails after installation.

2) Device theft: if your phone is stolen unlocked, the thief has access to your eSIM data connection. Always use strong device passcodes and biometric locks.

3) Profile cloning: extremely rare, but possible with sophisticated attacks. Use 2FA authenticator apps instead of SMS when possible. Enable Find My iPhone/Android Device Manager to remotely lock/wipe your device if stolen.

Question 25

Do I need to provide my passport to get an eSIM?

Accepted Answer

For most international travel eSIM providers: No. Services like Airalo, Holafly, and Nomad only require an email address and payment method. No passport, no ID, no address verification. This is one of the conveniences of eSIM vs physical SIMs. However, for local carrier eSIMs: Many countries require ID registration for SIM cards (physical or eSIM) due to local regulations. If you're buying directly from a local carrier, they may request passport details. Also, some countries have mandatory SIM registration laws that apply to all SIMs, though enforcement varies. Third-party travel eSIM providers typically don't require ID because they're operating under different business models.

Question 26

Will using a travel eSIM affect my privacy?

Accepted Answer

Travel eSIMs offer similar privacy to physical SIMs. Your data traffic goes through the local carrier network, which could theoretically monitor activity (just like any ISP). To enhance privacy:

1) Use a VPN on public Wi-Fi and when accessing sensitive information.

2) Use end-to-end encrypted messaging (WhatsApp, Signal) instead of SMS.

3) Avoid providing unnecessary personal information to eSIM providers.

4) Use privacy-focused browsers and DNS services. The main privacy advantage of eSIM: you can buy from providers that don't require ID verification, and you're not tied to your home carrier's tracking. The disadvantage: you're trusting a new provider with your data traffic.

Question 27

My QR code won't scan. What should I do?

Accepted Answer

Try these solutions:

1) Ensure good lighting and the QR code is in focus and fully visible on your screen or paper.

2) If viewing on another device, try zooming in or out on the QR code image.

3) Take a screenshot of the QR code and try scanning from your photos.

4) Clean your camera lens.

5) Try the manual entry method instead: in your phone's eSIM settings, choose 'Enter Details Manually' and type in the SM-DP+ Address and Activation Code provided by your eSIM vendor.

6) If none of this works, contact your provider. They can resend a new QR code or help troubleshoot.

Question 28

Why does my eSIM say 'No Service' or 'SIM Not Provisioned'?

Accepted Answer

'No Service' can mean several things:

1) The eSIM is installed but not activated: turn it ON in cellular settings.

2) You're outside the coverage area for your plan.

3) You need to manually select a network: Settings → Cellular/Mobile → Network Selection → Turn off automatic and choose a carrier.

4) Data roaming is off: some eSIMs require it to be enabled.

5) Airplane mode is on: turn it off. 'SIM Not Provisioned' usually means the profile wasn't fully installed or there was a network error. Try removing and reinstalling the eSIM profile. If the error persists after reinstalling, contact your provider for a new QR code.

Question 29

I used all my data too quickly. What happened?

Accepted Answer

Common culprits for rapid data consumption:

1) Background app refresh: apps updating in the background without you knowing. Disable in Settings.

2) Automatic cloud backup: iCloud Photos, Google Photos backing up over cellular. Turn off.

3) App updates: iOS/Android downloading app updates automatically. Disable auto-updates over cellular.

4) Video streaming: Netflix, YouTube, TikTok in HD quality. Just 1 hour can use 3GB.

5) Hotspot usage: sharing your connection with laptops uses data faster.

6) Video calls: Zoom/FaceTime video uses 200-500MB per hour. Check your data usage in Settings to see which apps consumed the most, and adjust settings accordingly.

Question 30

What if I have an issue with my eSIM provider?

Accepted Answer

Reputable eSIM providers offer customer support through multiple channels:

1) Live chat: usually 24/7 in the provider's app or website. This is the fastest way to get help.

2) Email support: submit a ticket with your order details. Response times vary from hours to a day.

3) FAQ/Help center: many issues are covered in self-service knowledge bases.

4) Phone support: some providers offer this, though less common. When contacting support, have ready: your order number, the device model, the exact error message, and screenshots if applicable. If you bought through a third party (like a travel booking site), contact them as well as the eSIM provider. For serious issues unresolved by support, dispute the charge with your credit card company.
