International students often set up their college account (e.g., campus portal) using their home-country phone number for OTP-based two-factor login, then realize that number won't be usable once they've physically moved to Canada.
What group members advised:- Keep recharging your Indian SIM remotely. You don't need to be physically in India to keep the number active — recharging periodically (e.g., a basic monthly plan, ~Rs 100/month was mentioned for one carrier) keeps the SIM live so OTPs still land on that number even while you're in Canada.
- Match the recharge plan to what you actually need. Make sure the plan you keep includes SMS/OTP delivery and not just data, so account verification and login codes continue to work while abroad.
- This matters for more than just college portals — the thread referenced a real case of a student being stopped by immigration/airport authorities partly because they couldn't complete an OTP-gated login. Set this up before travelling, not after you arrive.
The simple fix: don't let your home-country SIM lapse just because you've relocated — a small ongoing recharge keeps OTP-based logins working.
