You secured your phone. Now secure your phone number!
GrapheneOS protects your device. Efani protects the mobile number connected to your accounts, crypto and identity.
Your Security Stack Is Missing One Layer
You chose GrapheneOS because you take mobile security seriously. But securing the device is only part of the equation. Your phone number can still be targeted through SIM swaps, unauthorized number transfers and carrier-account attacks.
Together, they protect more of your mobile security stack.
A Secure Phone Doesn't Automatically Mean a Secure Number
Imagine spending hours hardening your phone.
- You install GrapheneOS.
- You minimize permissions.
- You use strong passwords.
- You enable hardware security keys.
Then someone targets the one thing connecting your phone to dozens of your accounts:
Your mobile number
A successful SIM swap or unauthorized number transfer can give an attacker control of calls and text messages—and potentially access to accounts that still rely on your number for authentication or recovery.
Efani Adds a Security Layer Your Operating System Can't
GrapheneOS controls what happens on your device. Efani controls what happens when someone tries to change, transfer or replace your mobile line.
Every sensitive account change goes through Efani's security process rather than being treated like a routine carrier request.
Sensitive account changes go through a proprietary multi-layer verification process rather than relying on a simple PIN or password.
Critical number-transfer requests are subject to a mandatory cooling-off period, adding another barrier against unauthorized transfers.
Sensitive changes receive manual review instead of relying entirely on automated carrier processes.
Two Different Threats. Two Different Layers of Protection.
Protects the operating system, applications, permissions, network access and attack surface of your phone.
Protects the mobile service layer from unauthorized SIM changes and number transfers.
Use strong passwords, authenticator apps and hardware security keys wherever possible.
Important: Do not present Efani as a replacement for hardware security keys, authenticator apps, passwords or GrapheneOS.
Built for People Who Don't Treat Mobile Security as an Afterthought
You already chose a security-focused operating system. Add protection for the number your device uses.
Keep your mobile service aligned with a privacy-first approach.
Protect the number that may be connected to exchanges, email accounts and financial services.
Add another layer to a carefully constructed personal security stack.
Your phone number can be a valuable target. Make unauthorized number transfers harder.
Your Carrier Was Built for Connectivity. Efani Was Built for Security.
Privacy Isn't Just About Your Operating System
GrapheneOS gives you powerful controls over what apps can access on your device.
But your mobile service provider is another part of your privacy equation.Efani is designed around a different philosophy:
Your mobile service should exist to connect you—not to monetize your personal information.
Designed without selling your customer information.
Additional separation between your identity and the underlying carrier infrastructure.
Built for people who want greater control over their mobile footprint.
Security That Goes Beyond the SIM
Multiple checks for sensitive account changes
Unauthorized SIM/eSIM changes are protected by Efani's security process.
Additional protection against unauthorized port-out requests.
Sensitive changes receive manual review.
Keep your U.S. number while traveling.
Use Efani with compatible eSIM-capable devices.

Security is about prevention first. But no security system should rely on a single layer. Efani's SAFE Plan includes up to $5 million in coverage for qualifying losses associated with covered SIM-swap incidents.

Quality of life literally mooning since switching my phone sim to @efani because they somehow find turbo fast internet connectivity globally no matter where you travel first time i’ve been able to trade and sports bet live in the bahamas without feeling like I am on a dial up modem
Devastating to hear this. I switched to @efani secure phone service a few weeks back. You'll never have to worry about sim swap again. Highly recommend.
I'd recommend @efani if you're looking for an alternative. I switched over last year after I became similarly terrified at the lack of security provided by all major carriers.
Stay vigilant out there as more & more phishing scams & sim swaps will happen as more #crypto adoption happens I want to plug my friend @haseeb as his company @efani will prevent Sim Swaps. #HODL #UnbankYourself
DO NOT GET SCAMMED Scammers r sending fake links to #Celsians. This is what happens when a #community grows exponentially fast like @CelsiusNetwork Many will target Celsius to see if they can get you to click on fake links Protect yourself - @efani (Prevents Sim Swaps)
Sim Swapping will continue as #crypto rises. @efani is a company that prevents Sim Swaps Very well respected founder @haseeb started this to prevent these Sim Swaps check out video @blockchainherd did with Haseeb to learn more https://youtu.be/89douuqwrNk #HODL @CelsiusNetwork
Personal phone number is one of the most valuable cyber economy/ identity assets today. Point much under appreciated and dangerous to personal cyber risk. First product in identify protection for consumers that makes me feel safer. Excited to become a customer @efani @haseeb
Telecoms found themselves in the cyber security business with the rise of 2FA. @efani is a cyber security company in the telecom business. Love being an early adopter of a cool product that understand security in the “Wild West” of data privacy world
Just switched to @efani secure cell phone service. Don't take the risk of getting Sim swapped. Protect yourself now!
Initial Security Round 1: 1. Guaranteed Protection Against SIM Hacking with @efani 2. Get secure and private access to the internet with @NordVPN 3. Get 2-factor authentication with Google Authenticator 4. Use a trusted email service with @ProtonMail
My phone recently got compromised and the perpetrator ported my phone number out. I reached out to NebreskaGooner and TheWolfAllStreets, who than put me in contact with Haseeb Awan, who helped me get my number and life back. Thank you Haseeb Awan - CEO of @efani ! You saved my A$$
If you win the customer's heart they will keep your company on exponential growth. @haseeb is one of few security authority and CEO who is not behind the curtains. Loyal customers are the most weighted asset in my perspective. Best of luck to @efani
Good work @lorenzofb! Right pointing backhand index “All of the major carriers made a significant change to how SMS messages are routed to prevent hackers being able to easily reroute a target's texts” @VICE(However, hackers can still SIM Swap mobile phones & carriers need to step up security) @haseeb
There's this company, @efani , run by a great guy ( @haseeb ) that specializes in protecting against porting. I made the switch off T-Mobile to @efani a couple months ago and sleep much better. Phone numbers are critical to keep secure, not a vector I want unprotected by my carrier.
After the BlockFi breach, I had a near miss SIM swap. Efani had me covered in less than 24hrs - on a Saturday no less. Military grade protection. Phone carriers cannot protect against employees bending the rules for insistent “customers” (scammers).
Times like this I am grateful that I take security seriously. All of you should too. Pay the extra money for it. I use @haseeb and @efani for starters, multisig in multiple locations, and most importantly perimeter sentries with 30mm ammunition. $BTC
Haseeb talked me down off a ledge during an attempted mobile & financial accounts hack over Christmas. @efani & @haseeb were there for me during most stressful time of my life and I’m eternally grateful. Folded hands Sleep soundly now. Great customer service, can’t recommend enough!
Thank you @scottmelker for the quick response and handoff to @haseeb . He helped me immediately and I'm switching to @efani as a result of this as he acted quickly on my behalf. I think we have things secured but 🤷♂️. Hackers got away with about $2k thusfar. @Ledger @coinbase
Anyone who does not evaluate having @efani secure your phone needs to take a few minutes and watch the video @blockchainherd did with @haseeb on how to secure your phone and protect you assets/crypto #HODL #UnbankYourself #Bitcoin #simswap
T-Mobile discloses data breach after SIM swapping attacks. This is the 5th data breach disclosed by T-Mobile in 4 years, all of them being reported after hackers gained access to customers' data. #SimSwap Mobile phoneWristwatch Switch to @Efani mobile!
