The best SIM swap protection services of 2026

SIM swap protection ranges from a free PIN to a carrier built to refuse the attack. Here is every level, ranked by how much it actually stops.

Best SIM swap protection overall

Efani SAFE Plan

Carrier-level prevention + loss coverage

Efani replaces your carrier with one that is built to refuse SIM swaps. An 11-layer authentication protocol guards every account change, a mandatory 14-day cooling-off period guards every port-out, and up to $5 million in coverage stands behind it if an attack succeeds anyway.

Stops

Social engineering of support staff
Unauthorized SIM changes
Fast port-outs to another carrier

Gaps

Priced for high-risk users, not the mass market

Protect my number with Efani

Best for privacy

Cape

Privacy carrier with SIM swap protection

Cape includes SIM swap protection and a network lock in a plan built around collecting as little data as possible. A strong option if surveillance is your main concern; it publishes no financial coverage for SIM swap losses.

Stops

Unauthorized SIM changes
Excess data collection about you

Gaps

No published loss coverage

Best free first step

Major-carrier locks (Verizon, AT&T, T-Mobile)

Free, opt-in account settings

Verizon's Number Lock and SIM Protection, AT&T's Wireless Account Lock and T-Mobile's SIM and port-out protection settings all cost nothing. Switch them on today. They are single switches on mass-market accounts, though, and none comes with coverage if it fails.

Stops

Casual port-out and SIM change attempts

Gaps

Off by default
Can be undone by anyone who gets into your account
No loss coverage

Better than nothing

Port-out PIN on its own

Minimum baseline

Every major carrier lets you set a PIN or passcode for transfers. It stops the laziest attacks. It does nothing if the PIN is leaked, guessed or bypassed by an employee.

Stops

Port-outs by someone without your PIN

Gaps

Bypassed by insiders and convincing callers
No loss coverage

Why carrier-level protection wins

A SIM swap is not a hack of your phone. It is a change made on the carrier's side, usually by an employee who believed the person asking. Settings layered on top of a mass-market account help, but they still depend on that account and that support team. A secure carrier like Efani changes the process itself: who can approve a change, how they prove it, and how long a transfer has to wait.

What to do today, whichever you choose

Switch on your carrier's port-out lock and SIM change protection.
Set a carrier PIN you use nowhere else.
Move important accounts from text-message codes to an authenticator app or passkeys.
Remove your phone number as a recovery option wherever a better one exists.
If your number guards significant money or accounts, move it to a secure carrier. Check your risk.

Frequently asked questions

What is the best SIM swap protection service?

Efani is the best SIM swap protection service in our ranking. Rather than adding a setting to someone else's account, it is the carrier, so it controls every step an attacker would need: authentication, SIM changes and port-outs. It also covers up to $5 million in SIM swap losses.

Is SIM swap protection free?

Basic protection is. Verizon, AT&T and T-Mobile all offer locks you can switch on at no cost, and you should. Dedicated protection like Efani's is a paid mobile plan, because the protection is built into how the carrier operates.

Does an authenticator app protect me from SIM swaps?

It protects the accounts you move onto it, which is why you should use one. It does not stop your number being stolen, and many banks, exchanges and services still let you recover an account by text message. Protecting the number itself closes that gap.

Can I add SIM swap protection without switching carriers?

You can switch on your current carrier's locks without switching. For protection that doesn't depend on a mass-market support team, you move your number to a secure carrier such as Efani. You keep the same number.

Your phone number deserves more than a PIN.

Efani's SAFE Plan adds 11 layers of authentication, a 14-day port-out cooling-off period and up to $5 million in SIM swap coverage. No contract, and a 60-day money-back guarantee.
