Question 1

What is an eSIM and how does it work?

Accepted Answer

An eSIM (embedded SIM) is a digital SIM profile built directly into your smartphone or tablet hardware. Instead of inserting a physical plastic SIM card, you simply scan a QR code provided by AeroSIM to download a cellular data profile in seconds.

Question 2

Do I need to remove my physical SIM card to use an eSIM?

Accepted Answer

No, you do not need to remove your physical SIM card. Modern smartphones support Dual SIM functionality, allowing your existing home SIM (for calls and 2FA SMS) to remain active while your AeroSIM eSIM handles high-speed mobile data abroad.

Question 3

What are the benefits of using a travel eSIM over local physical SIMs?

Accepted Answer

With a travel eSIM, you avoid airport SIM queues, high roaming fees, and the hassle of swapping tiny plastic cards. You can buy and install your data plan before departure and get connected the second your flight touches down.

Question 4

Do AeroSIM eSIMs include a local phone number for voice calls and SMS?

Accepted Answer

AeroSIM travel plans are high-speed mobile data plans. They do not come with a traditional cellular phone number for analog voice calls or SMS, but all VoIP messaging apps (WhatsApp, FaceTime, Telegram, Signal, iMessage, Skype) work seamlessly with zero extra configuration.

Question 5

Can I reuse the same eSIM for multiple trips or other countries?

Accepted Answer

Each AeroSIM profile is specifically provisioned for the destination and plan you selected. For multi-country journeys, we recommend our Europe 35+, Asia Multi-Country, or Global 130+ regional eSIM passes, which automatically roam across borders on a single profile.

Question 6

Which iPhone models support eSIM?

Accepted Answer

eSIM is supported on iPhone XS, XS Max, XR, and all iPhone 11, 12, 13, 14, 15, and 16 models (including Mini, Pro, and Pro Max editions), provided the device is carrier-unlocked. Note: iPhones purchased in mainland China, Hong Kong, or Macau with dual physical SIM trays generally do not support eSIM.

Question 7

Which Samsung Galaxy models support eSIM?

Accepted Answer

Question 8

Which Google Pixel phones support eSIM?

Question 9

How do I check if my phone is carrier-locked before buying?

Accepted Answer

On iPhone: Go to Settings > General > About > look for 'Carrier Lock' or 'Network Provider Lock'. It must say 'No SIM restrictions'.
On Android: Go to Settings > Network & Internet or Connections > Mobile Networks. If you can add multiple networks or if purchased directly from the manufacturer without an installment contract, it is usually unlocked.

Question 13

What is an SM-DP+ Address and Activation Code for manual installation?

Accepted Answer

If you cannot scan the QR code with your camera (for example, if viewing the QR code on the same device), you can enter the details manually:
- SM-DP+ Address: Provided on your order lookup page (e.g., `smdp.aerosim.global`)
- Activation Code: The unique matching token provided with your order
When prompted during setup, choose 'Enter Details Manually' and paste these two fields.

Question 14

When should I install my eSIM — before departure or after landing?

Accepted Answer

We recommend installing the eSIM at home or at the departure airport using stable WiFi before boarding your flight. The data validity countdown for most fixed-term plans only begins when the eSIM first connects to a supported local cellular tower in the destination country.

Question 15

Do I need an active internet/WiFi connection to install the eSIM?

Accepted Answer

Yes, downloading the encrypted eSIM profile from the telecom carrier server requires an active WiFi or cellular internet connection. Once downloaded and installed, no WiFi is required to activate mobile data upon arrival.

Question 16

When exactly does my plan's validity period (days) start counting down?

Accepted Answer

Your plan validity begins when the eSIM connects to a supported mobile network in the destination country for the first time. It does not start when you purchase the plan or when you scan the QR code at home.

Question 17

What happens when I run out of high-speed data?

Accepted Answer

When your allocated data allowance is depleted, data connectivity will pause to prevent surprise charges. You can quickly purchase a new top-up plan on AeroSIM.global and download a fresh QR code in under 2 minutes.

Question 18

Can I use Mobile Hotspot / Personal Tethering with my AeroSIM data plan?

Accepted Answer

Yes! Personal Hotspot and Tethering are fully supported on all AeroSIM plans at no extra charge. You can share your high-speed 4G/5G connection with your laptop, tablet, or travel companions.

Question 19

What network speeds can I expect (4G / 5G / LTE)?

Accepted Answer

AeroSIM partners with tier-1 mobile operators (like SoftBank/Docomo in Japan, AT&T/T-Mobile in the US, EE/Vodafone in the UK, Orange/TIM across Europe). You will receive 5G Ultra or high-speed 4G LTE wherever coverage is available from the local carrier.

Question 20

What is the difference between Daily Pass plans and Fixed Total Data plans?

Accepted Answer

- Daily Pass (e.g., 1GB/Day): You receive 1GB of fresh high-speed data every 24 hours. Great for daily steady usage and budgeting.
- Fixed Total Data (e.g., 10GB for 30 Days): You have 10GB total to use flexibly whenever you want during the 30-day window.
