A Comprehensive Efani Review (+ Customer Thoughts)

As major telcos continue to mishandle sensitive customer data—most recently demonstrated by the Salt Typhoon campaign disclosed in late 2024, which compromised at least nine U.S. carriers, including AT&T and Verizon (Efani's underlying networks)—consumers are increasingly turning to secure mobile carriers.

Efani has established itself as a popular choice, promising to prevent common attacks and bring peace of mind.

This Efani review will show you if the service delivers on its promise. You’ll learn:

• How Efani works and which security layers it offers
• What kind of coverage you get
• What users say about Efani

Efani at a Glance

Efani is a security-focused cell phone carrier that caters to high-risk individuals, such as:

• Executives
• Cryptocurrency investors
• Public figures

As such, it’s a high-end service that aims to protect consumers from network-level attacks, most notably SIM swaps.

Having fallen victim to mobile attacks themselves, Efani’s founders decided to build a service that either prevents security threats or mitigates their consequences. At the same time, the carrier promises to deliver broad network coverage and useful add-ons (more on that later).

While Efani mainly focuses on individuals, it also accommodates the security needs of businesses and government agencies. It pays special attention to companies subject to stringent SEC regulations, offering a fully compliant service with robust security measures.

How Efani Works

Efani doesn’t own cellular towers, and instead partners with major U.S. carriers for coverage. It leverages AT&T and Verizon’s infrastructure while adding its own security oversight. When you sign up, you can choose between these two networks and get nationwide 4G/LTE and 5G coverage.

This setup makes Efani a Mobile Virtual Network Operator (MVNO) that offers service through major carriers while managing your account separately. In other words, your personal data isn’t shared with AT&T and Verizon, which shields it from the many types of attacks these carriers have encountered over time.

To get started with Efani, consumers go through four steps:

1. Signing up: Besides phone number and billing information, Efani requires the user’s name and address for signup (which isn’t ideal if you prefer anonymity).
2. Choosing or porting a number: Efani recommends port in, and handles the process on the user’s behalf (which typically lasts around 10 minutes).
3. Choosing a SIM: Efani lets users choose between a physical SIM and eSIM, though the latter is recommended to eliminate the risk of someone stealing or swapping a physical SIM.
4. Going through identity verification: After a user signs up, Efani requires a verification call, during which the team checks their ID and relevant details. After verification, the line is activated within a few minutes.

Efani Secure Mobile Review

To give you a full picture of Efani’s functionalities, we’ll cover the following aspects separately:

1. Security
2. Plans and add-ons
3. Pricing
4. Customer support

Security

Among the several types of mobile attacks consumers might fall victim to, Efani focuses particularly on SIM swapping as the most common one. It offers the so-called “11-layer security protocol,” which is a series of automated and manual checks conducted when the user wants to make notable changes to their account (e.g., porting a number).

Some of the key security measures are outlined in the following table:

Efani states these measures are so effective that no malicious party has even gotten through them. The service prides itself on a 100% success rate and zero breaches (including internal and carrier-side ones).

For select organizations with particularly high risks, Efani offers Black Seal Protection—a solution that protects from attacks like:

• DDoS attacks
• SS7/Location Tracking Attack
• Fake tower attacks

Unfortunately, Black Seal Protection is invite-based and isn’t available to the general public.

To further increase customer confidence, Efani offers $5 million cyber insurance. If a user suffers any form of financial loss stemming from a successful attack, the company will cover up to $5 million of the damages.

Plans and Add-Ons

Efani offers one plan that includes:

• Unlimited calling and texting: Efani’s unlimited plan extends to all domestic numbers within North America (so Canada and Mexico are included as well).
• Unlimited data: Users get unlimited 4G/5G data (though after 40 GB of usage within a month, data speed will slow down to lower priority levels).
• International roaming: Efani offers free international data roaming covering various countries for consumers who opt for an eSIM.

The service’s broad offering accommodates the target audience’s needs, seeing as high-risk individuals often need a secure domestic and international connection.

Besides the standard plan, Efani lets consumers choose three add-ons outlined in the following table:

Efani offers custom solutions for businesses and government agencies, the details of which are available upon request. For organizations in highly regulated industries, the service includes SEC-compliant solutions with features like:

• Secure communication archiving
• AI-assisted compliance management
• Employee training and education

Pricing

Efani’s pricing model is straightforward—consumers can choose between two payment options:

1. Monthly: $99
2. Annually: $999

There are no carrier fees or hidden charges, so you’ll only pay extra if you choose one of the available add-ons (the pricing of which isn’t readily available as of this writing).

Efani doesn’t require contracts, which might be particularly beneficial for business users who wish to avoid vendor lock-in. There’s also a 60-day money-back guarantee, so you can get a full refund if you’re unhappy with the service.

All things considered, Efani offers decent value for money, especially if you’re a high-risk individual requiring multiple protection layers.

Customer Support

Efani offers 24/7 white-glove support through three channels:

1. Email
2. Phone
3. Chat

The around-the-clock assistance from a dedicated team feeds into Efani’s premium-level offering. Instead of typical carriers that might leave you on hold for quite a while, you can get personalized and immediate assistance if you encounter any issues.

Efani also assigns consumers to a specific security team responsible for monitoring their account charges. This increases the overall security level and creates a closer relationship with the provider’s team.

Efani Reviews: What Customers Say

Efani has various high-profile consumers who are happy with the service. The service is particularly popular among crypto investors, many of whom highly recommend Efani.

One user highlighted the “VIP customer service” as a main benefit besides Efani’s security measures. They said that the more intimate relationship with the customer support team further decreases the risk of SIM swaps and provides a more pleasant experience overall.

Still, not everyone shares this opinion. One customer complained specifically about Efani’s customer support, claiming the team disregarded their warning about having their phone hacked. The team told the user to schedule an appointment, which goes against the advertised immediate support.

Another user shared this sentiment, assuming that Efani only had a few employees due to lackluster customer service.

Given that Efani seems to have a small team (fewer than 20 employees are listed on LinkedIn at the time of writing), this might be a valid concern. While Efani’s boutique service setup enables a closer relationship with consumers, it also raises questions about whether the team can maintain that relationship as the user base grows, a conflict well-reflected in the mixed customer reviews.

The Verdict: Is Efani Worth It?

Efani is undoubtedly more secure than traditional carriers, so it might make sense to switch if you fit the profile of its target audience. The extensive checks following the account change request are effective enough to lower the risk of SIM swapping, and you can enjoy the peace of mind knowing that your data isn’t shared with carriers Efani partners with.

The service might also be a solid choice for organizations that want to streamline SEC compliance through strong network security and efficient archiving workflows.

Still, you should be aware of some pitfalls if you decide to look into Efani more closely.

The first and potentially most concerning one is privacy. While Efani closes many security gaps of commercial telcos, it somewhat retains their trust-based approach. You need to entrust Efani with personal information provided at signup, which isn’t a gold-standard practice among privacy-first mobile services.

There’s also a matter of transparency, which could be improved. Efani’s Privacy Policy is quite slim and doesn’t provide details on how personal data is safeguarded. The company only states it will protect the data “within commercially acceptable means,” without any specifics.

If you want the highest level of data protection, it’s best not to hand out your personal information in the first place. To enjoy such security, choose a mobile service that asks for minimal personal data, such as Cape.

Cape Makes Security the Standard: Here’s How

Cape is America’s privacy-first mobile carrier, providing premium, unlimited, and nationwide call, text, and data. Unlike other providers, our service is built from the ground up with privacy and security at its core.

Mainstream carriers track you and store your data, often without your consent. Cape takes a different path—we collect the absolute minimum amount of information to provide you with service.

Any information we do collect is retained for the minimum amount of time possible. Most carriers store call data records (CDRs) for years, sometimes indefinitely. Cape stores yours for just 24 hours, and we have a commitment to never sell your data.

Cape service includes security features that no other carrier offers:

• Minimal Data Collection: During onboarding, we don’t ask for your name, Social Security number, or address. We only collect what’s necessary to provide you with service, and we retain it for the minimum amount of time possible.
• Identifier Rotation: Every SIM card has an International Mobile Subscriber ID (IMSI), a unique identifier which your device uses to register with cellular networks. Most carriers assign a fixed IMSI that stays the same for the life of your account, making it easy for your carrier, advertisers, and bad actors to identify and track your device over time. Cape breaks that pattern by allowing subscribers to automatically rotate their IMSI every 24 hours, so you appear as a different subscriber every day, making it much more difficult for anyone to follow or track your movements.
• Secondary Numbers: Your phone number is a target for data brokers and scammers. Retailers, websites, apps—everyone is routinely asking you to share your number with them, which exposes you to a variety of risks. Many turn to VoIP numbers to use as secondary lines, which can be helpful, but cost extra, don’t work with 2FA, and aren’t encrypted. Cape provides subscribers with two free additional SMS/MMS lines that are middle-to-end encrypted. With secondary numbers, you can reserve your primary number for communicating with your close friends and family, and use the other for anything from shopping and signing up for discounts, to receiving secure OTPs.
• Disappearing Call Logs: Call and text records reveal a lot about you, from who your closest relationships are to when and where communication took place. With traditional carriers, your call and text metadata doesn’t just disappear; it’s retained, analyzed, and folded into a lasting customer profile. At Cape, we’re built to forget and delete these records after just one day.
• SIM Swap Protection: A SIM swap happens when an attacker convinces your carrier to transfer your number to their device, allowing them to receive your calls and texts, trigger password resets, and gain access to your accounts. Cape protects against SIM swaps by removing humans entirely from the loop. During sign-up, you receive a 24-word phrase that generates a private key tied to your number. This phrase is the only way to move your number to a new device or carrier. No one, not even Cape, can transfer your number without your phrase, giving you full control over your number.
• Network Lock: Traditional cellular networks were designed for interoperability, not security. Outdated and legacy network protocols like SS7 have vulnerabilities that allow attackers to hack in and track your location, intercept your calls and texts, and steal sensitive information. Cape’s Network Lock uses a proprietary signaling proxy to verify that your device’s physical location matches the network it’s trying to attach to. If anything looks suspicious, like a mismatched location, we block the connection.
• Encrypted Voicemail: Voicemails can reveal more than you think, from personal messages to authentication codes, yet most voicemail systems are outdated and unencrypted. Cape encrypts your voicemails so that only you can access them.
• Secure Global Roaming: While you’re traveling abroad, your phone connects to local telecom providers to provide you with connectivity. But not all networks are secure, and not all governments treat privacy the same. Cape routes your traffic through our U.S.-based mobile core. Our Secure Global Roaming gives you the convenience of international data roaming without exposing your identity or communications. You get up to 15GB per month of international roaming included in your plan.

These features are made possible because we’re a “Heavy” Mobile Virtual Network Operator (MVNO).

Other MVNOs (such as Mint Mobile, Cricket, etc.) simply ride on top of the mobile core, SIMs, and physical infrastructure of their underlying MNO partner. At Cape, we actually own our own mobile core and provision our own SIMs.

This gives us control over how accounts are authenticated, what data we do and don’t collect, how long we retain it for, as well as the ability to build proprietary features like Identifier Rotation. No other carrier on the market has this capability.
