Frequently Asked Questions
Quick answers before you pick your destination plan.
An eSIM (embedded SIM) is a digital SIM card built directly into your smartphone - no physical chip to swap.
A travel eSIM lets you buy a local data plan for your destination country online, before you even leave home. You receive a QR code by email, scan it with your phone, and you're connected the moment you land. No airport SIM kiosks, no roaming surprises on your regular phone bill.
The main difference is cost and control:
- Your home carrier's roaming: May include some data in certain regions, but outside those zones, especially in Asia, the Americas, Africa, or the Middle East, charges can be very high, sometimes several dollars per MB.
- Teclapi eSIM: Connects you to a local carrier network at local rates. For destinations outside your home region, the saving can reach 70–80% compared to standard international roaming.
Worth checking: Some home plans do include free roaming in certain countries - verify your plan before buying, especially if you're traveling within a region your carrier already covers.
Yes. Teclapi eSIMs are data-only - they don't replace your main SIM. Your home SIM stays active alongside the eSIM on the same device. You'll continue receiving calls, SMS, and WhatsApp notifications on your regular number, while the eSIM handles your mobile data at local rates abroad.
Most Teclapi plans are data only — they don't include a local phone number for traditional calls or SMS. That said, with a reliable data connection, you can call and message freely through WhatsApp, FaceTime, FaceTime Audio, Telegram, Messenger, or any VoIP app. That's how most travelers communicate today anyway.
For some destinations, Teclapi plans come with a phone number included. This means you can make and receive regular calls and SMS just like a local SIM, on top of your data allowance.
Check the plan details for your destination at checkout to see whether a phone number is included.
In most cases, yes - significantly so. For destinations like Japan, Thailand, the US, or Morocco, a Teclapi eSIM plan covering 7–30 days of data typically costs between $5 and $20. Your carrier might charge that much for a single day of international roaming.
No. Purchasing a Teclapi eSIM requires no identity verification. Just choose your destination, select a plan, pay, and your QR code arrives by email instantly. No passport, no registration, no waiting.
On iPhone: Go to Settings → General → About → scroll to "Carrier Lock". If it shows "No SIM restrictions", you're unlocked. Also look for "Digital SIM IMEI" in the same screen — its presence confirms eSIM support.
On Samsung: Settings → About Phone → Status Information → IMEI Information. If you see "IMEI (eSIM)", your device supports it.
On any Android: Dial *#06# and press call. If an EID number appears alongside your IMEI, your phone is eSIM-capable.
As a general rule, iPhones from the XS (2018) onward, Samsung Galaxy S21+, Google Pixel 3+, and most recent flagships are compatible. Check the full device list on our website.
Teclapi plans are optimized for iOS and Android smartphones. Some cellular-enabled tablets (iPad with cellular, Samsung Galaxy Tab) and certain laptops (Surface Pro, some Dell/HP models) also support eSIM — check your specific device before purchasing.
If your tablet or laptop isn't eSIM-compatible, the easiest workaround is sharing your phone's data connection via personal hotspot.
Three categories to match any trip:
- Local plans — data usable in a single country. Best value if you're staying in one place.
- Regional plans — data shared across a zone (e.g. Europe, Southeast Asia, Americas). Ideal for multi-country itineraries.
- Global plans — data usable in 70–200+ countries. Perfect for frequent travelers or digital nomads.
Durations range from a few days to 30 days, with data allowances from 500 MB to 20 GB and above.
Validity starts when you install the eSIM profile on your device — not when you first use data, and not when you purchased it. Avoid installing too early. The smart approach: buy your eSIM as soon as you've booked your trip for peace of mind, but don't scan the QR code until 24 hours before departure.
Tip: Buy early, install late. You can purchase weeks in advance and sit on the QR code until the day before you fly.
A practical guide by usage type:
- Light (500 MB – 1 GB/day): Maps, messaging, occasional web browsing — no video streaming.
- Moderate (1–2 GB/day): Social media (Instagram, TikTok), video calls, navigation, checking reviews.
- Heavy (3 GB+/day): Streaming YouTube or Netflix, large uploads, remote work, sharing your connection with a laptop.
For a 10-day trip with moderate use, a 10–15 GB plan is usually comfortable. If your accommodation has reliable Wi-Fi in the evenings, 5–7 GB is often enough.
