International Roaming Teardown

Japan Roaming Playbook: Escaping Carrier Daily Passes

1. The $16/Day Roaming Pass Trap

Canadian Tier 1 carriers charge up to $16.00 per calendar day for international roaming (Roam Like Home / Roam Better / Easy Roam). This fee consumes your domestic Canadian data bucket while generating $224 in extra fees on a 14-day trip.

Silent Background Data Triggers:

Even without answering calls or opening browser apps, background iCloud sync, email push, or a single incoming SMS delivered over cellular will immediately trigger the full $16/day charge.

2. Dual-SIM Setup & Local Breakout Routing

Modern smartphones allow running your primary Canadian SIM alongside a digital Travel eSIM simultaneously. Keep your Canadian number active for free SMS 2FA while channeling all cellular data through the local eSIM.

1. Cellular Data

Set Cellular Data to the Travel eSIM. Turn OFF "Allow Cellular Data Switching" to prevent accidental data fallback to your Canadian carrier.

2. Canadian SIM Roaming

Turn "Data Roaming" OFF on your Canadian SIM. Enable Wi-Fi Calling to receive calls and 2FA SMS over hotel Wi-Fi at $0.00.

3. CRTC $100 International Roaming Cap

Under the CRTC Wireless Code Section E1, carriers are prohibited from billing more than $100 in international data roaming per billing cycle without explicit customer consent. Once reached, data is suspended until you explicitly authorize additional usage.
