Protecting Your VIP Phone Number for Life
终身守护您的幸运靓号资产：CRTC 携号转网所有权保护、防 SIM Swap 盗号与回国出海 $0~$3 保号全攻略
A lucky phone number in Canada is an enduring personal asset. Under CRTC Wireless Number Portability (WNP) mandates, subscribers maintain absolute ownership and can transfer numbers between carriers at $0 cost. However, high-value numbers require proactive defense against SIM swap hijacking, alongside cost-efficient parking strategies when traveling abroad.
在加拿大，精心挑选的幸运靓号属于受法律保护的个人终身资产。根据加拿大广播电视电信委员会（CRTC）携号转网法规，消费者拥有绝对的号码支配权，换运营商 100% 免费带走且原运营商无权扣留。同时，高价值靓号必须配置严密的转网保护 PIN 码以防范“补卡盗号（SIM Swap）”，并在长期离境或回国期间通过 90 天免费缓冲或 Wi-Fi Calling 实现 $0 成本保号。
1. CRTC Wireless Number Portability (WNP): You Own Your Number / 携号转网法定权利：号码归你所有
Under CRTC Telecom Decision 2005-72 and the Wireless Code, Canadian consumers enjoy strict regulatory protections governing their telephone numbers:
Carriers are legally prohibited from blocking a port-out request due to contract status or billing disputes.
To port your lucky number, keep your old line ACTIVE. Your new carrier initiates the port and automatically cancels the old plan.
CRTC rules mandate that number portability must be provided free of charge by all telecommunications providers.
2. Defending Against SIM Swap Attacks on High-Value Numbers / 抵御“补卡劫持（SIM Swap）”盗号攻击
High-visibility numbers (like 416-888-8888) are prime targets for social engineering fraudsters who impersonate the subscriber to steal 2FA SMS and drain bank accounts:
Log into your carrier account or call customer care to attach an explicit Port-Out Security PIN. Under CRTC security guidelines, a port request will be immediately rejected unless the exact PIN is supplied.
在运营商后台设置专属 Port-Out PIN 码。未输入该专属密码的任何转网平移申请将被系统自动拦截并报警。
Require your carrier to place a high-security note on your file requiring a secondary verbal passphrase and 2 pieces of physical government photo ID for any SIM replacement.

Frequently Asked Questions & Policy Gotchas
Can my carrier refuse to port my phone number if I have an unpaid bill? ▼
No. Under CRTC Wireless Number Portability (WNP) rules, Canadian carriers cannot withhold or block a number port due to billing disputes or outstanding account balances. The port must be completed immediately, and billing disputes must be handled through standard debt collection processes rather than number retention.
What is a SIM Swap attack and how do I protect my VIP phone number? ▼
A SIM Swap occurs when a malicious hacker social-engineers carrier customer support into reassigning your phone number to a new SIM card under their control, allowing them to intercept your banking 2FA SMS and reset account passwords. To protect yourself: 1) Set a mandatory 6-digit Port Protection Password with your carrier; 2) Add a strict Verbal PIN requirement for all in-store and phone support inquiries; 3) Never use SMS as the sole 2FA method for critical financial accounts.
