International Travel SIM & eSIM
Use your phone abroad without the $1,000 surprise.
The problem
Without a plan, US carriers charge $10+/MB overseas. One Google Maps session = $30. A few photo uploads = $200. Many travelers come home to bills $500-$2,000 higher than expected.
Best option for most travelers — eSIM
An eSIM is a digital phone plan you buy on your phone. No physical card. Set it up at home before you fly. Most modern phones (iPhone 14+, recent Samsung Galaxy, Google Pixel) support eSIM.
Airalo
App-based. Plans for 200+ countries. About $5-10 for 5GB / 7-30 days. Best value for short trips.
Holafly
Similar. Slightly more expensive but offers UNLIMITED data plans (worth it if you stream).
Saily (by NordVPN)
Often slightly cheaper than Airalo for the same destinations.
GigSky
Older option, large network coverage, slightly pricier.
Setup (Airalo as example)
- Install Airalo from App Store / Play Store BEFORE leaving home.
- Browse → pick your destination → pick a data plan.
- Pay with credit card or Apple Pay.
- App walks you through installing the eSIM (2 minutes).
- Enable mobile data on the eSIM ONLY — disable your US carrier\'s data while traveling.
- You keep your US phone number for texts/calls (over Wi-Fi). Data uses Airalo.
Compare to your US carrier\'s plan
- T-Mobile Magenta/Go5G — free 5G data in 215+ countries (slow). Worth not paying anything extra. Top tiers include faster speeds.
- AT&T International Day Pass — $12/day for your usual plan. Quick trips: convenient. Long trips: very expensive.
- Verizon TravelPass — $10/day. Same idea.
- Google Fi — same plan, same price, same data overseas. Best for frequent international travelers.
Math: 7-day trip on AT&T Day Pass = $84. Same trip on Airalo = $5-15. Airalo wins for any trip longer than 1-2 days.
Stay phone-bill-safe
- Before flying — Settings → Cellular → "Cellular Data" OFF for your US line.
- Settings → Cellular → Data Roaming OFF on US line.
- iMessage and FaceTime work over Wi-Fi anywhere — free.
- Use airport / hotel / cafe Wi-Fi when you can.
- Download Google Maps offline of your destination BEFORE you fly.
Old-fashioned alternative
Buy a local prepaid SIM at the airport in your destination. About $10-30, often unlimited. Works on phones older than 2020 that don\'t support eSIM. Major airports always have a stand selling them.
