How to Use eSIM When Traveling Abroad

Confession: I used to dread landing in new countries. That moment when you step off the plane, phone screams "NO SERVICE," and you spot the *epic 40-person line* at the SIM kiosk? Yeah... not anymore.

Here’s my foolproof eSIM routine – tested from Bali to Barcelona – so you can skip the chaos:

Activate Any Plan, Anywhere!
Land in Bali at 2 AM? Just scan a QR code or tap an app, and boom—you’re online. No hunting for stores, no waiting for delivery. I’ve switched plans between flights while sipping airport coffee. That’s the magic.. ”

✈️ Step 1: Buy Your eSIM Before Takeoff (Seriously!)

Do this with your pre-flight espresso:

  1. 1.Hop onto airsim.us → My go-to for global plans (cheaper than airport SIMs, zero plastic waste).

  2. 2.Filter by country/region (e.g., "Thailand" or "Europe Regional").

  3. 3.Pick your data pack → I usually grab 5GB for 10 days ($10-15).

  4. 4.Checkout → They email a QR code + install guide.
    Pro Tip: Screenshot that QR code AND save it to Google Drive/Dropbox. (Losing it = stress you don’t need!)

📱 Step 2: Activate in 90 Seconds Flat

(Yes, even mid-flight!)

  1. 1.Land → Turn off Airplane Mode.

  2. 2.Go to Settings → Cellular → "Add eSIM"

  3. 3.Scan your QR code (or tap "Enter Details Manually" if QR fails).

  4. 4.Label it something fun → "Tokyo Tiktok Data" 😉

  5. 5.Toggle it ON → Set as "Cellular Data" source
    Boom. You’re online before baggage claim.

🌍 Pro Moves for Savvy Travelers

  • -Switch Plans Like a Spy:
    Hopping from Italy to Greece? Turn off "Pasta Data," turn on "Souvlaki SIM." No tools, no drama.

  • -Two eSIMs at Once?
    (iPhone 14+/Pixel 7+ only): Keep your home number for texts + use airsim.us for data. Genius for banking OTPs.

  • -Save Data Like a Boss:
    → Download maps/playlists on hotel Wi-Fi.
    → Turn OFF "Data Roaming" for your home SIM.


⚠️ 4 Critical Checks (Don’t Learn This the Hard Way!)

  1. 1."Is My Phone UNLOCKED?"
    → Text your carrier: "Unlock my phone for int’l travel." *Do this 72hrs pre-flight!*

  2. 2."Does My Phone Support eSIM?"
    → Most iPhones (XR & newer) and Pixels work. Check here.

  3. 3."Can I Tether?"
    → Need laptop Wi-Fi? Buy plans with "Hotspot Allowed" (airsim.us shows this clearly!).

  4. 4."How Much Data?"
    → Socials + Maps: ~3GB/week
    → Netflix/YouTube: +1GB/day


💡 My "Oh Crap" Backup Plan

Sometimes networks glitch (looking at you, rural Portugal!). My fix:

  1. 1.Keep a $20 backup eSIM from airsim.us for emergencies

  2. 2.OR buy a cheap local SIM (but only if QR codes fail!)


Why This Changed Everything

Last month in Bangkok:
→ Landed at 1AM → scanned my airsim.us QR at arrivals → ordered Grab → posted IG Stories...
All before passport control. Cost? $7 for 5GB. Stress? Zero.


Your Turn:

  1. 1.Browse airsim.us tonight (their "Regional" packs save $$$).

  2. 2.Buy → Save QR code like digital gold.

  3. 3.Land → Scan → Conquer.

Welcome to stress-free travel. ✨
