Comments on Silent Phone - Secure Calling for Android

★★★★★ Sophie Smith · Aug 8, 2020

Works very well. However, like all other encryption apps, you need to convince family and friends to use it. I do appreciate the encrypted calling or use the silent phone for a second line feature. The security is worth the price.

★★★★★ Jay Terelli · Nov 12, 2020

Great app need; need email credit card (debit?) for people who can't get it to work or new users its very simple 1. DL app 2 register act.(need an email) 3 LOGOUT OF APP, MAKE SURE U WRITE DOWN ACT LOGIN 4. Login ur email 5 click the verify email (that's why u logout) 6 click on pay $10 mo fee 7 then u have to pay for a ph # the price depends on country, works by a credit system. U charge ur card by the $ u need (credits) u don't pay for the # by cc only credits (this is where most get lost

★★★★★ Gregory Potter · Sep 16, 2020

Works great on my Note9. Encrypted voip over VPN, secure real-time transport protocol, end-to-end authentication, and a unique phone number, and developed by the creator of PGP encryption, Phil Zimmermann. What's not to love.

No SMS texts please fix title says phone calls and messaging, but it's only meant for phone calls misleading baD!!

★★☆☆☆ Woody · Dec 30, 2024

Would be nice to know the price structure before having to hand over personal/business details. Until it's listed, me, my business & my staff will continue to use Signal & pay them a monthly fee, which is totally voluntary, but I like to support worthwhile organizations. I heard about the feature where I can call a person on a landline who doesn't have the app, but it would go through, so the call would still be secure, private & untraceable, but no pricing for that either, which is a real shame

★☆☆☆☆ John Smith · May 16, 2020

Can you please add paid future, so we can text non SC members on other carrier such as Mobile, Sprint etc
